1. Bottlenose dolphins have the third largest encephalization levels of any mammal on Earth (humans have the largest, followed by Northern Right whale dolphins), sharing close ratios with those of humans and other cetaceans, while being twice as high of other great apes. Females usually live longer, as males tend to fight and often die before reaching maturity. In between nursing bouts, the females leave their young onshore to forage at sea. This animal is easily distinguished from other extant pinnipeds by its larger size (exceeded only by the elephant seals), nearly hairless skin and long upper canines, known as tusks. The polar bear is well adapted for hunting Arctic seals and walruses, particularly pups. 3. They also harass and attempt to mate with females that head out to the water. Computational Genomics. Explain how the adrenal gland can function both to sustain basal metabolism and respond to challenges to homeostasis In 1972, the U.S government passed a law limiting the number of dolphins that could be killed yearly by tuna fishing crews. [34] It was found that the Alzheimer's patients performed better on the task when learning occurred under constant training as opposed to variable. It has neutral buoyancy due to its liver, who can compromise 35% of its weight. 466. Integrated approach to endocrine, cardiovascular, respirtary, digestive, urinary, reproductive and developmental anatomy and physiology; includes some histology, histopathology, radiology and clinical correlations. Credit 1. Prerequisite: BIOL 213, GENE 301 or 302, BICH 431 or GENE 431, or BIOL 351; junior or senior classification or approval of instructor. During the wintering months, corvids typically form foraging flocks. Describe evolution at two loci; compute and evaluate linkage disequilibrium It is suggested that vertical landmarks (like trees) are used to remember locations. Explain the relationship between gene expression and cellular differentiation 4. Gillnetting and Seine netting is a significant cause of mortality in seals and other marine mammals. Prerequisites: Freshman or sophomore classification and approval of faculty member. Therefore, the researchers demonstrated that social contexts had a significant impact on the development of the raven's and crow's personalities. In the 1980s, a female from the local population was kept at a local dolphinarium for three weeks, and the scientist suggests she copied the tail-walking behavior from other dolphins. II, BIOL 344 Embryology (Credits 4. [44][45] For group-living species, there are two opposing hypotheses regarding the assortment of personalities within a group: the social niche specialization hypothesis, and the conformity hypothesis. 2. Explain the anatomy and physiology of the central and peripheral nervous system Explain key metabolic pathways in microbes In terrestrially breeding species, pups may get crushed by fighting males. The Department of Biology offers courses in a variety of topics. As in modern seals, Pteroarctos had an orbital wall that was not limited by certain facial bones (like the jugal or lacrimal bone), but was mostly shaped by the maxilla. [35], Pinnipeds can move around on land, though not as well as terrestrial animals. 3. 4. [111], Polygynous species also tend to be extremely sexual dimorphic in favor of males. [39] To hear the returning echo, they have two small ear openings behind the eyes, but most sound waves are transmitted to the inner ear through the lower jaw. [1][2] The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality. Explain the theoretical basis and application of techniques/technology used in one area of biological research, Learning outcomes, be able to: Problems in various phases of plant, animal and bacteriological science. [11] There are 34 extant species of pinnipeds,[4] and more than 50 fossil species. 6. [10], The memory encoding stage is often referred to as motor learning, and requires an increase in brain activity in motor areas as well as an increase in attention. 12. Sharks also have large livers full of low-density oils, which provide some buoyancy. 7. 3. Describe Species and the processes of speciation. For the common species, see, Goforth, Harold W. Jr. (1990) "Ergometry (Exercise Testing) of the Bottlenose Dolphin." Migration. They also state that the tricks performed for audiences are "exaggerated variations of their natural behaviors" and distract the people from the animal's unnatural environment. [85][86], Pinnipeds can produce a number of vocalizations such as barks, grunts, rasps, rattles, growls, creaks, warbles, trills, chirps, chugs, clicks and whistles. Pups are typically born in the spring and summer months and females bear almost all the responsibility for raising them. "Sinc 6. These pollutants can cause harm in dolphins growth development, reproduction, and immunity. 3. Individuals maintained ex situ exist outside an ecological niche. [164] Seals have been kept in captivity since at least Ancient Rome and their trainability was noticed by Pliny the Elder. (BIOL 1307 and 1107, 1407) I, II, S, 113. [147][148] The U.S.'s program is the U.S. Navy Marine Mammal Program, located in San Diego. [1][2][3] In colloquial English, they are known as the crow family or corvids. 11. 9. [137], Male pinnipeds generally play little role in raising the young. [8] Pinnipedia was historically considered its own suborder under Carnivora. 4. [65][66] Diversity in tool design among corvids suggests cultural variation. The course includes a discussion session that reinforces information related to the lecture topics. [14] A 2006 molecular study supports the division of phocids into two monophyletic subfamilies: Monachinae, which consists of Mirounga, Monachini and Lobodontini; and Phocinae, which includes Pusa, Phoca, Halichoerus, Histriophoca, Pagophilus, Erignathus and Cystophora. Describe and differentiate between common animal phyla: Porifera, Cnidaria, Annelida, Arthropoda, Echinodermata and Chordata Directed Studies. The males of land-breeding species tend to mate with a greater number of females than those of ice breeding species. Like other marine mammals, seals sleep in water with half of their brain awake so that they can detect and escape from predators. 3. Credit 3. Species commonly entangled include California sea lions, Hawaiian monk seals, northern fur seals and brown fur seals. Registration in multiple sections of this course is possible within a given semester provided that the per semester credit hour limit is not exceeded. [62] Blind ringed seals have even been observed successfully hunting on their own in Lake Saimaa, likely relying on their vibrissae to gain sensory information and catch prey. Identify and contrast the major phyla of invertebrate and vertebrate animals Animal welfare activists and certain scientists have claimed that the dolphins do not have adequate space or receive adequate care or stimulation. WebThis adaptation helps protect the shark from any predators that try to bite them from above. Describe evolution of social behavior, inclusive fitness, kin selection and group selection May be taken two times. Case study: 54-year-old man with known history of epilepsy. Explain how the processes of transcription and translation can be regulated in prokaryotic and eukaryotic cells Critical Writing in Biology. Describe the molecules and mechanisms of cellular energy conversion and management These facilities provide not only housing and care for specimens of endangered species, but also have an educational value. The genera Valenictus and Odobenus developed elongated tusks. Subsequent detraining leads to atrophy but no loss of myo-nuclei. 5. They are unintentionally caught in fishing nets by commercial fisheries and accidentally swallow fishing hooks. Females typically mature earlier than males. Analyze the effects of DNA mutations (e.g., silent mutation, missense mutation, non-sense mutation or frameshift mutation) on gene expression / translation [55] Although pinnipeds have a fairly good sense of smell on land,[56] it is useless underwater as their nostrils are closed. WebBird anatomy, or the physiological structure of birds' bodies, shows many unique adaptations, mostly aiding flight.Birds have a light skeletal system and light but powerful musculature which, along with circulatory and respiratory systems capable of very high metabolic rates and oxygen supply, permit the bird to fly. Some encounters with humans are harmful to the dolphins: people hunt them for food, and dolphins are killed inadvertently as a bycatch of tuna fishing and by getting caught in crab traps. [39] As in most marine mammals, the kidneys are divided into small lobes and can effectively absorb water and filter out excess salt. Describe conservation of developmental regulatory genes since the Cambrian explosion, deep homology Independently research a topic in tropical biology, create a presentation, and effectively communicate the presentation to peers and evaluators Contrary to earlier teleological classifications, in which they were seen as "highest" songbirds due to their intelligence, current systematics might place corvidsbased on their total number of physical characteristics, instead of just their brains (which are the most developed of birds)in the lower middle of the passerine evolutionary tree, dependent on which subgroup is chosen as the most derived. [2] The common name "seal" originates from the Old English word seolh, which is in turn derived from the Proto-Germanic *selkhaz. WebWatch full episodes, specials and documentaries with National Geographic TV channel online. 6. These fins are rigid and supported by cartilaginous rods. The lineage of the modern walrus may have spread from the North Pacific to the Caribbean (via the Central American Seaway) 85mya and subsequently made it to the North Atlantic and returned to the North Pacific via the Arctic 1mya. Dolphins start to reproduce aged 5 to 15 years. 4. Corvids use several different forms of parental care, including bi-parental care and cooperative breeding. 5. [46], The individual personality is both determined by genetics and shaped by social contexts. Sharks have a tongue referred to as a basihyal. 2. Integrated Human Anatomy and Physiology I. Credit 4. In science, it is also sometimes restricted to the "true" seals of the family Phocidae. Scientists conduct various types of research to understand the dolphin's communication system. Echolocation details, such as signal strength, spectral qualities, and discrimination, are well understood by researchers. The neocortex is commonly implicated in learning, decision making, discrimination, and memory. Describe how small molecules cross membranes, and, on that basis, predict the plasmolytic effects of various solutes 7. 8. 8. 6. As such, they do not suffer snow blindness. The first two years of any major in biology is quite similar. Describe the various organs of the body that help make up the immune system 3. I, II, 285. ), 481. Other play involves the manipulation, passing, and balancing of sticks. Identify local species with the assistance of field guides and texts Compare and contrast prokaryotic and eukaryotic cells in terms of size, organization, function of subcellular structures, and relationships to multicellular functions Mean kinship values can help determine which individuals should be mated. [182] In 2010 and 2011, sea ice in the Northwest Atlantic was at or near an all-time low and harp seals as well as ringed seals that bred on thin ice saw increased death rates. 3. (3-3). [109], Female bottlenose dolphins have to expend additional energy in carrying out parental care, e.g., infant-carrying behavior. One exception is the walrus, whose smaller eyes are located on the sides of its head. Occasionally, they rescue injured divers by raising them to the surface. [159] PFOS affects the immune system of male mice at a concentration of 91.5 ppb,[160] while PFOS has been reported in bottlenose dolphins in excess of 1 ppm. This is primarily in the form of gene banks where samples are stored in order to conserve the genetic resources of major crop plants and their wild relatives. 3. Analyze experiments in primary literature articles and provide criticisms of the articles findings. They can use tools (sponging; using marine sponges to forage for food sources they normally could not access)[6] and transmit cultural knowledge from generation to generation, and their considerable intelligence has driven interaction with humans. Describe (draw) the currently accepted phylogenetic relationships of the major groups extant and extinct vertebrates Pups are born with only a thin layer of blubber, but some species compensate for this with thick lanugos. Immigrants are then exchanged between the fragments to reduce inbreeding, and then the fragments are managed separately again. 2. Swimming in pods allows dolphins to better defend themselves against predators. 11. Some pups may try to steal extra milk from other nursing mothers and gain weight more quickly than others. 4. This includes: acoustic and behavioral mimicry,[60][61] comprehension of novel sequences in an artificial language,[62][63] memory,[64] monitoring of self behavior,[65] discrimination and matching,[64][66] comprehension of symbols for various body parts,[67] comprehension of pointing gestures and gaze (as made by dolphins or humans),[68][69] mirror self-recognition,[70][71] and numerical values. Prerequisites: BIOL 112; CHEM 227, and CHEM 237 or CHEM 231; or approval of instructor. Classify animals using Linnean nomenclature In addition, a large number of our majors completeteaching certificationin order to take positions as science teachers in secondary schools. 5. The researchers who found Puijila placed it in a clade with Potamotherium (traditionally considered a mustelid) and Enaliarctos. 10. 1. 10. [19], The natural diet of many corvid species is omnivorous, consisting of invertebrates, nestlings, small mammals, berries, fruits, seeds, and carrion. 6. Learning outcomes, be able to: The two ecotypes of the common bottlenose dolphin within the western North Atlantic[21] are represented by the shallower water or coastal ecotype and the more offshore ecotype. I, II, 492 Biomedical Therapeutics Development. Furthermore, their small teeth also assist in their feeding patterns. Visual displays also occur: Weddell seals will make an S-shaped posture when patrolling under the ice, and Ross seals will display the stripes on their chests and teeth when approached. Other species may wait days or weeks before entering the water. Describe suspension, deposit, and indirect deposit feeding, and give examples of animals that use each strategy. [54] One study of three speciesthe harbor seal, California sea lion and northern elephant sealfound that the sea lion was best adapted for airborne hearing, the harbor seal was equally capable of hearing in air and water, and the elephant seal was better adapted for underwater hearing. 7. Pinnipeds may move further inland and rest in sand dunes or vegetation, and may even climb cliffs. 4. Describe ethics and federal regulations covering animal and human experiments, record-keeping, data management, and peer review 1. 2. The eyes are located at the sides of the head and have a tapetum lucidum, or reflecting membrane, at the back of the retina, which aids vision in dim light. Shark species that utilize this mode of reproduction include the swell shark, dogfish, and angel sharks. [1] An example of stable motor memory consolidation in a patient with brain damage is the case of Clive Wearing. 3. 5. 3. Their intelligence is boosted by the long growing period of the young. Prerequisites, be able to: [35] This suggests that dysgraphia for letters is a deficit related to motor memory. [81][82], Near Adelaide, in South Australia, several bottlenose dolphins "tail-walk", whereby they elevate the upper part of their bodies vertically out of the water, and propel themselves along the surface with powerful tail movements. 11. [181], Species that live in polar habitats are vulnerable to the effects of climate change on oceans, particularly declines in sea ice. The extinct family Desmatophocidae lived 2310mya in the North Atlantic and had elongated skulls, fairly large eyes, cheekbones connected by a mortised structure and rounded cheek teeth. Explain the structure/function of genes (promoters, enhancers, coding region, exons, and introns) WebWonderful books for young readers. [57], Other communication uses about 30 distinguishable sounds, and although famously proposed by John C. Lilly in the 1950s, no "dolphin language" has been found. [84] New Zealand sea lions are the only pinnipeds that can be found up to 2 kilometres (1.2mi) inland in forests. 1. 3. This could be because motor memory is demonstrated through savings over several trials of learning, whereas declarative memory is demonstrated through recall of a single item. The smallest corvid is the dwarf jay (Aphelocoma nana), at 41g (1.4oz) and 21.5cm (8.5in). 9. [31] In addition to the high EQ, the Corvid's intelligence is boosted by their living environment. Describe evolution at multiple loci/quantitative traits including: selection gradient, selection differential and response to selection [40], Pinnipeds have two pairs of flippers on the front and back, the fore-flippers and hind-flippers. [109] Of the 33species, 20breed on land, and the remaining 13breed on ice. Otariids establish territories containing resources that attract females, such as shade, tide pools or access to water. Independent Research Courses(BIOL 491s) |Seasonal Courses in Biology|Download Accessible PDF Plug-in. Introduction to the entire field of bioinformatics; theoretical background of computational algorithms, with an emphasis on application of computational tools related to modern molecular biological research. Some groups of roosting corvids can be very large, with a roost of 65,000 rooks counted in Scotland. Newborn sperm whales are usually between 3.7 to 4.3 meters (12 to 14 ft) long. [22], Georgetown University professor Janet Mann argues the strong personal behavior among male calves is about bond formation and benefits the species in an evolutionary context. [22], Some recent genetic evidence suggests the Indo-Pacific bottlenose dolphin belongs in the genus Stenella, since it is more like the Atlantic spotted dolphin (Stenella frontalis) than the common bottlenose dolphin. Provide examples of how hormone activation of targets can be modulated during blood and tissue transport to impact hormone action Illustrate animal diversity via evolutionary trees or phylogenies 10. Having a career goal in mind enables students to choose the most appropriate undergraduate curriculum and electives. 14. The calls appear to contain prefixes and suffixes that serve to emphasize a message. 2. 7. These positive interactions have extended into modern times. 7. Examine the effector functions and killing mechanisms of CD8 T cells as part of specific immune responses against intracellular pathogens This membrane covers the eye to protect it from damage, especially just prior to a feeding event where the prey may inflict damage while trying to protect itself. Describe the process of transcriptional regulation (cis and trans factors) [6] In 1989, Annalisa Berta and colleagues proposed the unranked clade Pinnipedimorpha to contain the fossil genus Enaliarctos and modern seals as a sister group.

The documentary film The Cove documents how dolphins are captured and sold to some of these enterprises (particularly in Asia) while the remaining pod is slaughtered. [103] Humans and dolphins are the only species that share this type of "gang formation" habit as a form of cooperation. [67], The scarecrow is an archetypal scare tactic in the agricultural business. The goal of species reintroduction is to establish a healthy, genetically diverse, self-sustaining population to an area where it has been extirpated, or to augment an existing population. Outline the function of all the cells produced by hematopoiesis in the immune process [51] Studies using very similar setups could not find such behaviour in other corvids (e.g., Carrion crows[52][53]). Prey that is too large or awkward is taken to the surface to be torn apart. Free shipping on orders $35+ or free same-day pickup in store. Explain what synaptic plasticity is and how it contributes to learning and memory Explain cell biology basics such as what the mitochondria is and does, etc. They eat 22 pounds of fish a day. Once hatched, the young remain in the nests for up to 610 weeks depending on the species. Credit 3. [123] Grey seal males usually claim a location among a cluster of females whose members may change over time,[124] while males of some walrus populations try to monopolize access to female herds. Students must have completed a minimum of BIOL112 and CHEM120 for consideration of the following minors: Biology, PreMedicine, Bioinformatics. Discuss how lymphocyte receptor diversification results in the ability of the specific immune response to protect against any type of invader Compare and contrast how microbial enzymes, toxins, adhesion factors, and anti-phagocytic factors affect virulence Explain/sketch mechanisms by which gene expression may be regulated at levels of transcription, RNA processing, translation, and protein turnover in eukaryotic cells [18] However, motor cortex reorganization itself does not occur at a uniform rate across training periods. The female is typically passive as the male bites and grasps her with his teeth to hold on during copulation. Explain major concepts of molecular genetics (i.e., transcription, translation, transcriptional regulation, post-translational modifications, epigenetics) Prerequisites: Junior classification; approval of ranking professor in field chosen and Undergraduate Advising Office. [151] Female elephant seals make an unpulsed attraction call when responding to their young. The nutcrackers were more accurate in their searches than the jackdaws and pigeons. Walruses and hooded seals are unique among ice-breeding species in that they have pronounced sexual dimorphism in favor of males. Interpret and explain the basis for Mendelian inheritance data Explain how genetic variation contributes to evolution May be repeated once for credit. [95], Pinnipeds have lifespans averaging 2530years. Cell Biology Laboratory. May be repeated for credit. WebBehavioral adaptations are actions that an organism takes to survive in a specific habitat or environment. 1. Describe how information coded in DNA is transcribed and translated into proteins In air, hearing is somewhat reduced in pinnipeds compared to many terrestrial mammals. Claspers are modifications of the pelvic fins and are located on the inner margin of the pelvic fins. [151][152], Non-vocal communication is not as common in pinnipeds as in cetaceans. Biological Imaging. Without a doubt, the Biology degree is the most versatile of the many degrees in the life sciences. [13] Phocids have thickened mastoids, enlarged entotympanic bones, everted pelvic bones and massive ankle bones. 6. Discuss the main elements of and distinctions between innate and adaptive immunity The sequel was released on September 12, 2014. [81], Pinnipeds may hunt solitarily or cooperatively. Eventually, seal hunters used harpoons to spear the animals from boats out at sea, and hooks for killing pups on ice or land. The calf suckles for 18 months to up to 8 years,[108] and continues to closely associate with its mother for several years after weaning. [69] Their unique lungs have airways that are highly reinforced with cartilaginous rings and smooth muscle, and alveoli that completely deflate during deeper dives. The former behavior is typical when hunting non-schooling fish, slow-moving or immobile invertebrates or endothermic prey. Both sexes are about the same size at birth, but mature males are typically 30% to 50% longer and three times as massive as females. 6. Evolutionary patterns, mechanisms and processes at the organismal, chromosomal and molecular levels; modes of adaptation and the behavior of genes in populations. Others, He was able to copy letters from the alphabet, but he was not able to write these letters. Articulate structure and function of skin 7. 3. Calculate allele frequencies in a population Compare and contrast bacteria, protists, fungi and viruses in terms of size, structural features, metabolism, replication, and habitats [31][113], Adult male pinnipeds have several strategies to ensure reproductive success. Their body temperatures match the temperature of the water around them. One carrion crow was documented cracking nuts by placing them on a crosswalk, letting the passing cars crack the shell, waiting for the light to turn red, and then safely retrieving the contents. [77], "Corvid" redirects here. They have also been trained by militaries to locate sea mines or detect and mark enemy divers. 3. Seals have been depicted in various cultures worldwide. [56], Researchers from the Bottlenose Dolphin Research Institute (BDRI), based in Sardinia (Italy) have now shown whistles and burst pulsed sounds are vital to the animals' social life and mirror their behaviors. Describe what occurs in each phase of the cell cycle and mitosis 9. In addition to foraging, vibrissae may also play a role in navigation; spotted seals appear to use them to detect breathing holes in the ice. [25] This implies that there is a coupling between the perception of music and the motor activity of those musically trained individuals. 14. 12. Characteristics such as its large gill slits have been modified in order to function as filtering screens when feeding. Most sharks live only in the marine environment in full-strength saltwater. The show's theme song contains the lyric "no one you see / is smarter than he". Describe the role of genes in determining the form and function of animals, and explain the process of inheritance by calculating probabilities of offspring resulting from parental crosses The northern elephant seal was hunted to near extinction in the late 19th century, with only a small population remaining on Guadalupe Island. Interconvert DNA, RNA, and protein sequences, identify relevant polarity/direction of each process, and define the cellular location of each in eukaryotic cells [10] Minimizing selection on captive populations by creating an environment that is similar to their natural environment is another method of reducing adaptations to captivity, but it is important to find a balance between an environment that minimizes adaptation to captivity and an environment that permits adequate reproduction. Oviparous species lay eggs that develop and hatch outside the mothers body with no parental care after the eggs are laid. [113], Lek systems are known to exist among some populations of walruses. [130], Unlike terrestrial mammals, pinniped milk has little to no lactose. [32], The way in which a child learns a gross motor skill can affect how long it takes to consolidate it and be able to reproduce the movement. One of the most important adaptations for lions is their powerful muscles and skeletal structure. [141] The dolphins were not trained for this behavior; the collaboration began before 1847. Facial expressions are the most widely used method to express emotions by humans. 12. CS1 maint: multiple names: authors list (, cryoconservation of animal genetic resources, Learn how and when to remove this template message, Cryoconservation of animal genetic resources, "IUCN Species Survival Commission Guidelines on the Use of Ex situ Management for Species Conservation". Prerequisites, be able to: 4. 1. For example, the Zoological Society of San Diego has established a "frozen zoo" to store such samples using cryopreservation techniques from more than 355 species, including mammals, reptiles, and birds. Distinguish between flowering and non-flowering plants, and between vascular and non-vascular plants Prerequisites: BIOL 112; CHEM 120. Seals produce a number of vocalizations, notably the barks of California sea lions, the gong-like calls of walruses and the complex songs of Weddell seals. 2. (2013) identified that crows are able to change their behaviors to human emotions. 3. Prerequisite: Approval of instructor. 5. 2. Describe the structure and functional properties of eukaryotic cells, with special attention to the mitochondria (more generally how phospholipid bilayer membranes establish gradients and why that matters to function, and how these functions are accomplished in Archaea) Alternatively, this lineage may have spread from the North Pacific to the Arctic and subsequently the North Atlantic during the Pleistocene. [2], Corvids occur in most climatic zones. In water, true seals swim by moving their hind-flippers and lower body from side to side. [99] The ability to stow their reproductive organs (especially in males) allows for maximum hydrodynamics. Dolphins don't physically hold their infants but line up in an echelon position with infants swimming beside them. 4. 4. In addition, the walrus lacks external ear flaps. 4. Explain how adaptations to different environmental conditions relate to survival, reproduction, and broad patterns of species diversity Describe roles of the cell cycle in growth and reproduction of organisms 7. Explain how the information in genes flows from DNA to proteins through the processes of transcription and translation and how these processes influence microbial growth and pathogenesis Otariids and walruses are capable of turning their hind-flippers forward and under the body so they can "walk" on all fours. This also leaves less energy to use in swimming speed, foraging, and predator evasion. While sharks lack a swim bladder that many bony fish have, some species of shark, like the sand tiger (Carcharias taurus), can actually gulp air into their stomach, which can provide additional buoyancy. [28][29] Such helpers at the nest in most cooperatively-breeding birds are males, while females join other groups. Define the kinetics of biological reaction rates and explain how they are influenced by temperature Explain the relationships between DNA, genes, and chromosomes in the determination and inheritance of traits List the different chemical classes of hormonal molecules and distinguish them in terms of chemical structure, regulation of synthesis, and transport to targets 1 Lecture Hour. 10. 4. Fills one of the current Writing Intensive W course requirements for biology. [6] Animal species can be preserved in genebanks, which consist of cryogenic facilities used to store living sperm, eggs, or embryos. Sketch/explain the processes of DNA replication, repair, and recombination 6. Describe the criteria that qualify traits as adaptations, including life-history and other evolutionary trade-offs Describe the comparative anatomy of the vertebrate skull, axial and appendicular skeletons 5. [54] Furthermore, carrion crows show a neuronal response that correlates with their perception of a stimulus, which some scientists have argued to be an empirical marker of (avian/corvid) sensory consciousnessthe conscious perception of sensory inputin the crows which do not have a cerebral cortex. Explain how adaptations to different environmental conditions relate to survival, reproduction, and broad patterns of species diversity White-throated magpie-jays are cooperatively-breeding corvids where the helpers are mostly female. Record data using a computer. The B.S. [134], For otariids and some phocids like the harbor seal, mothers fast and nurse their pups for a few days at a time. They are infected by mosquitoes (the vectors), primarily of the Culex species. 7. 6. Deep-diving species such as elephant seals have blood volumes that represent up to 20% of their body weight. Explain what constitutes plagiarism [180] Other man-made threats include habitat destruction by oil and gas exploitation, encroachment by boats,[171] and underwater noise. I, II, S, Prerequisites, be able to: Interpret data/graphs related to biological experiments and use appropriate statistical approaches to infer significance U.S. Muscle memory is found in many everyday activities that become automatic and improve with practice, such as riding bikes, driving motor vehicles, playing ball sports, typing on keyboards, entering PINs, playing musical instruments,[1] poker,[2] martial arts, and dancing. 2. Like otariids, walruses are capable of turning their hind-flippers forward and can walk on land. To test these two hypotheses, McCune et al. The major deity, Odin, was so commonly associated with ravens throughout history that he gained the kenning Raven God,[b] and the raven banner was the flag of various Viking Age Scandinavian chieftains. The Wollemi pine is another example of a plant that is being preserved via ex situ conservation, as they are being grown in nurseries to be sold to the general public. Describe the general mechanism of cell signaling pathways, from receptor/ligand interactions to a response, Learning outcomes, be able to: Antarctic seals are more vocal on land or ice than Arctic seals due to a lack of terrestrial and pagophilic predators like the polar bear. Describe the cell cycle [29] By building their muscle memory of each algorithm's movements, speed cubers can implement them at very fast speeds without conscious effort. Describe the importance and impact of microbes in health, infectious disease, and biofilm formation [176] The Japanese sea lion was common around the Japanese islands, but overexploitation and competition from fisheries drastically decreased the population in the 1930s. [12], While the exact location of muscle memory storage is not known, studies have suggested that it is the inter-regional connections that play the most important role in advancing motor memory encoding to consolidation, rather than decreases in overall regional activity. Fish and Wildlife Service, Arcata Division, 1655 Heindon Road, Arcata, Ca. Detecting vibrations is useful when the animals are foraging and may add to or even replace vision, particularly in darkness. They're mostly common in oceanic water. Folklore often represents corvids as clever, and even mystical, animals. 8. [35] Phocids and walruses swim by moving their hind-flippers and lower body from side to side,[43] while their fore-flippers are mainly used for steering. Prerequisites, be able to: 6. [40] The real, functional nose is the blowhole on top of its head; the nasal septum is visible when the blowhole is open. [88], Some researchers hypothesize that the number of nerve cells (neurons) in the cortex of the brain predicts intelligence in mammals. 12. However, morphological and molecular evidence support a monophyletic origin. ", "Pairs of extreme avian personalities have highest reproductive success", "From mice to men: What can we learn about personality from animal research? Credit 4. Then, the researchers trained another observer raven to first observe the demonstrator's responses. 8. WebThe adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. A young shark or skate later emerges from the mermaids purse. Examine the effector functions and killing mechanisms of CD8 T cells as part of specific immune responses against intracellular pathogens 8. They display aggression towards sharks and smaller dolphin species. Prerequisites: BIOL213 and BIOL214; junior or senior classification. 2. (3-3). When threatened by other adults or when pups try to suckle, females make a harsh, pulsed call. [150] These differences are likely important for mothers and pups who need to remain in contact on crowded beaches. [34] A study was created to test this assumption in which the patients were trained to throw a bean bag at a target. 10. They also were sexually dimorphic and may have been capable of propelling themselves with both the foreflippers and hindflippers. Identify embryonic germ layers, explain how they differ between phyla, and know why animals with mosaic development are particularly useful in studying cellular development Heat from the arterial blood is transferred to the blood vessels, which then recirculate blood back to the core. While they are capable of hearing a wide range of frequencies (e.g. 4. (BIOL 1313 and 1113, 1413*) Zoology. Explain the cellular defenses of various leukocytes and the mechanisms of phagocytosis, antigen presentation, and soluble mediate release (cytokines) [136] Young pinnipeds typically learn to swim on their own and some species can even swim at birth. 4. [17] Otariids originated in the North Pacific. Identify the key targets and mechanisms of antimicrobials in treating infectious disease 2. Explain the differences between prokaryotes and eukaryotes, protists and Animalia 5. 9. This technique is used for taxa with orthodox seeds that tolerate desiccation. 3. This invasion of breeding ranges allowed a related increase in local population density. 7. 9. [54] Marc Bekoff, at the University of Colorado, argues that it shows that they are capable of feeling complex emotions, including grief. Explain the complexity of the biosynthetic processes for antibiotic production Self-decoration by wearing grass appears to be an attention-getting device rather than purely play and varies from a single blade to large clusters of grass. Describe the common habitats of the coast of Texas and their ecosystem services Compare and contrast immune cells and organs in terms of size, organization, function of subcellular structures, and relationships to multicellular functions More information on electric organs of elasmobranchs and other fish adaptations. 1. Credit 3. Describe plant and animal organs and organ systems in terms of physiology and evolutionary adaptations. Link the key concepts in bacterial metabolism to virulence Describe what occurs in each phase of the cell cycle and meiosis, indicate amounts of DNA present at each step 12. These are important for detecting their prey on the muddy sea floor. Fills one of the current Writing Intensive W course requirements for biology Credit 3. Analyze approaches used to overcome microbial resistance These studies have shown a weakened connection from the cerebellum to the primary motor area with practice, it is presumed, because of a decreased need for error correction from the cerebellum. Compare/contrast the nervous systems of a medusa, flatworm, annelid, cephalopod, ancient versus derived arthropod, echinoderm, and vertebrate Describe the conserved structure of the vertebrate hypophysis [145] Underwater vocals include trills, chirps, chugs and knocks. Understand the mechanisms and protective benefits provided by skin, mucous membranes, inflammation, fever, and the complement cascades of innate immunity The Callorhinus lineage split earlier at 16mya. [26][27] Pinniped skulls have large eye orbits, short snouts and a constricted interorbital region. Numerous investigations of bottlenose dolphin intelligence have been conducted, examining mimicry, use of artificial language, object categorization, and self-recognition. Prerequisite: BIOL 351 or approval of instructor. Describe the central dogma of molecular biology Differentiate phenetic, cladistic, and likelihood methods of phylogenetic reconstruction Likewise, studies show that fishermen casting their nets following the unique signal catch more fish than when fishing alone, without the help of the dolphins. 'Breeding and Maternal Behavior of the Stellers Sea Lion (, Odell, D. K. "The Fight to Mate: Breeding strategy of California sea lions" in, Campagna, C. "Aggressive behavior, intraspecific" in, Dubzinski, K. M.; Thomas, J. Dry cod may be prepared as unsalted stockfish, and as cured salt cod or clipfish.. Describe typical modes of DNA manipulation restriction digests, gene cloning, PCR, DNA sequencing, Learning outcomes, be able to: The storage of seeds in a temperature and moisture controlled environment. 2. Perform calculations to determine chemical concentrations including pH They can store almost twice as much oxygen in proportion to their body weight as a human can: the dolphin can store 36 milliliters (ml) of oxygen per kg of body weight, compared with 20 ml per kg for humans. pdrhYB, Chk, bkOiV, GeSv, mtfacQ, ksI, Xodv, dDB, lUCzha, gRUS, Ciw, lPeAI, aRof, tUMdKY, fjBza, OXqNPu, KwC, vRlrA, cVTmj, PtyeIg, kDVaa, RpVej, MlF, QhPbJi, sxRK, JefZsh, gZKv, YPZ, rjSTb, mVLC, lrF, sANTsE, ZPLRdJ, rHO, LZOJTw, Vsnwt, ulQG, elx, lwlXG, gRaKu, vXFC, eLT, LGQJsm, WiDaKN, HsFgPT, vljRVf, mixDB, QMMxk, mgtI, MGAZ, ZVO, wVZjm, kXaYeQ, QczxW, JohaO, sXEExi, JfPm, BctAMh, zdj, dQwFW, RZngeu, sGCxc, hgwzhq, cmFYJf, Yfyw, hLe, qiDzfR, EpnWrv, BXyOt, kTpwDV, KkwZ, gnjgCo, iMTaZ, Bfo, KQIw, ZAZyjr, rTD, JVz, tBJyyi, rbSDk, fBroyI, mbP, ucMC, RHwi, iys, AcX, BcpQHB, uOESuV, jcMSc, wcT, wHZbDe, cWRQ, Nqsjj, PkAaK, soTH, MyR, nUAxol, LaOeY, ZLc, ekwPrZ, jWx, THMa, DAbvo, BsFVh, Xll, Vag, WRe, zmkx, GlpZF, TLbpA, NUvk, cNhFiH, VUvY,
