1. The corvids constitute the core group of the Corvoidea, together with their closest relatives (the birds of paradise, Australian mud-nesters, and shrikes). Describe the cell cycle Identify major groups of non-photosynthetic protists, know their habitats and which ones pose threats to human health [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. Restricted to senior undergraduate majors in biology, microbiology, botany or zoology. Once hatched, the young remain in the nests for up to 610 weeks depending on the species. Other sources also accept the Pacific bottlenose dolphin (T. t. gillii or T. gillii),[18] that inhabits the Pacific, and has a black line from the eye to the forehead.

Define homoplasy (analogy) Otariids and walruses are capable of turning their hind-flippers forward and under the body so they can "walk" on all fours. Explain how immune responses can be linked to either the elimination or exacerbation of the disease process Describe the structure and function of the unique water-vascular system of echinoderms Business, industry, and governmentcontinues to hire many of our graduates where skills and knowledge in the life sciences are in great and growing demand. 6. 2. 6. 2. Compare and contrast mechanisms of horizontal gene transfer Describe mechanisms of morphogenesis, including general architecture of animal tissue, epithelial-mesenchymal transition, and cell migration [139] Male California sea lions have been observed to help shield swimming pups from predators. These primitive walruses had much shorter canines and lived on a fish diet rather than a specialized mollusk diet like the modern walrus. Firstly, Corvids are found in some of the harshest environments on Earth, where surviving requires higher intelligence and better adaptations. 3. [22] They also hunt alone, often targeting bottom-dwelling species. Prerequisite: BIOL 351 or equivalent or approval of instructor.

May be repeated once for credit. The position of the azure-winged magpie, which has always been of undistinguished lineage, is less clear than previously thought. 1. Explain what constitutes plagiarism [9] Of the three extant families, the Otariidae and Odobenidae are grouped in the superfamily Otarioidea,[10] while the Phocidae belong to the superfamily Phocoidea. Discuss the main elements of and distinctions between innate and adaptive immunity WebStructural adaptations can affect the way the creature moves, eats, reproduces or protects itself. Discuss how lymphocyte receptor diversification results in the ability of the specific immune response to protect against any type of invader These fins are rigid and supported by cartilaginous rods. (1-0). Seals usually require cool, nutrient-rich waters with temperatures lower than 20C (68F). The world’s sandy 1. These students have one year upon transferring to complete BIOL213, BIOL214, CHEM227/237 and 228/238. Elephant seals do not swim until weeks after they are weaned. [65][66] Diversity in tool design among corvids suggests cultural variation. In this publication, he traced the history of names, gave keys to families and genera, described North American species and provided synopses of species in other parts of the world. Discuss the mechanisms of cell mediated immunity the T lymphocyte response 5. 11. Describe chordate embryology (basic) up through the neurula stage [10] However, if the genetic disorder is recessive, it may not be possible to completely eliminate the allele due to its presence in unaffected heterozygotes. WebCamels have a series of physiological adaptations that allow them to withstand long periods of time without any external source of water. However, the New Zealand sea lion has been recorded diving to a maximum of 460m (1,510ft) and a duration of 12 minutes. Also, it was found that gross motor memory in Alzheimer's patients was the same as that of healthy adults when learning occurs under constant practice. 6. 4. Compare and contrast how microbial enzymes, toxins, adhesion factors, and antiphagocytic factors affect virulence 2. [126] Alternative mating strategies also exist in young male grey seals, which do have some success. 4. Define symbioses and give examples from coral reefs, deep-sea ecosystems, and coastal habitats 2. Since the land they breed on is fixed, females return to the same sites for many years. Over half of our majors (in all of our degrees) go on for an advanced degree such as the Master of Science or the Doctor of Philosophy (Ph.D). [52] Seals release large amounts of mucus to protect their eyes. [22] To accelerate nursing, the mother can eject milk from her mammary glands. Explain major concepts of molecular genetics (i.e., transcription, translation, transcriptional regulation, post-translational modifications, epigenetics) Perform genome analyses using Cyverse In the mid-nineteenth century, the species was thought to have gone extinct until a small colony was found near the Yucatn Peninsula in 1886. 9. [81] The walrus is unique in that it consumes its prey by suction feeding, using its tongue to suck the meat of a bivalve out of the shell. WebBehavior of the Whale Shark These sharks are very slow moving, and spend much of their time cruising and feeding. Solve algebraic problems 8. WebBehavioral adaptations are actions that an organism takes to survive in a specific habitat or environment. 7. Explain the fundamental principles of cardiovascular and circulatory physiology [4] Findings related to the retention of learned motor skills have been continuously replicated in studies, suggesting that through subsequent practice, motor learning is stored in the brain as memory. However, Clive still retains access to his procedural memories, to be specific, the motor memories involved in playing the piano. 1. Demonstrate a basic understanding of molecular biology Course includes laboratory that reinforces and provides supplemental information related to the lecture topics. 2. Males of sexually dimorphic species also tend to have secondary sex characteristics, such as the prominent proboscis of elephant seals, the inflatable red nasal membrane of hooded seals and the thick necks and manes of otariids. Explain the relationship between genes/alleles and variation among organisms [116] Male harp seals, crabeater seals and hooded seals follow and defend lactating females in their vicinityusually one or two at a time,[125] and wait for them to reach estrus. 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. Describe plant and animal organs and organ systems in terms of physiology and evolutionary adaptations. Define homology The individual hairs on the coat, known collectively as lanugo, can trap heat from sunlight and keep the pup warm. Interpret data/graphs related to biological experiments and use appropriate statistical approaches to infer significance 2. This dimorphism manifests itself in larger chests and necks, longer canines and denser furall traits that help males in fights for females. Corvids also take part in other activities, such as sliding down smooth surfaces. 8. 4. Nevertheless, when disturbed by intruders harbor seals and Baikal seals may slap their fore-flippers against their bodies as warnings. 6. [102][133][134][135][136] The bottlenose dolphin is capable of defending itself by charging the predator; dolphin 'mobbing' behavior of sharks can occasionally prove fatal for the shark. [25] It has been found that there are often functional differences in the brains of professional musicians, when compared to other individuals. (3-3). Ravens are believed to be able to be sensitive to other's emotions. Explain what behavioral ecology has taught us about why animals behave differently 13.

[35][36][37] This extreme age is rare and less than 2% of all Bottlenose dolphins will live longer than 60 years. These tissue masses, which contain extensive contorted spirals of arteries and thin-walled veins, act as blood reservoirs that increase oxygen stores for use during diving. As the object of interest is approached, the echo becomes booming, and the dolphins adjust by decreasing the intensity of the emitted sounds. The female is typically passive as the male bites and grasps her with his teeth to hold on during copulation. The show's theme song contains the lyric "no one you see / is smarter than he". 2. It has been suggested that the synaptogenesis and motor map reorganization merely represent the consolidation, and not the acquisition itself, of a specific motor task. [51] The extraocular muscles of the walrus are well developed. 5. Labs include study of preserved material and demonstration of living animals in aquaria and terraria. Distinguish between flowering and non-flowering plants, and between vascular and non-vascular plants We have gathered complete information about the Polar Bear Height to give you a clear idea about its height both when it is on its four legs or [22] Providing mutual aid has also been recorded within many of the corvid species. Furthermore, ex situ conservation techniques are often costly, with cryogenic storage being economically infeasible in most cases since species stored in this manner cannot provide a profit but instead slowly drain the financial resources of the government or organization determined to operate them. Immigrants are then exchanged between the fragments to reduce inbreeding, and then the fragments are managed separately again. Explain what is meant by an animal model, Learning outcomes, be able to: 2. Compare and contrast prokaryotic and eukaryotic cells in terms of size, organization, function of subcellular structures, and relationships to multicellular functions The other major group of highly intelligent birds of the order Psittaciformes (which includes 'true' parrots, cockatoos, and New Zealand parrots) is not closely related to corvids. 3.

Outline the function of all the cells produced by hematopoiesis in the immune process [63][64] Other corvids that have been observed using tools include: the American crow, blue jay, and green jay. While most vocals are audible to the human ear, a captive leopard seal was recorded making ultrasonic calls underwater. 3. Sharks use the senses of smell (chemoreception), vision, hearing, the lateral line system, and electroreception (ampullae of Lorenzini) for capturing prey. Distinguish between living and non-living entities [49] Pinnipeds appear to have limited color vision, as they lack S-cones. Explain how the processes of transcription and translation can be regulated in prokaryotic and eukaryotic cells [120] The underwater vocals of Weddell seals can last 70 seconds, which is long for a marine mammal call. Compare and contrast methods and purposes of the ELISA and immunoblotting tests 3. 2. Various Germanic peoples highly revered the raven, and the raven was often depicted as a motif on shields or other war gear in Anglo-Saxon art, such as the Sutton Hoo burial, and Vendel period art. They are also the core group of the Corvida, which includes the related groups, such as Old World orioles and vireos.[11]. Prerequisites Molecular studies show the genus definitively contains two species: the common bottlenose dolphin (Tursiops truncatus) and the Indo-Pacific bottlenose dolphin (Tursiops aduncus). Link the effects of DNA damage to the excision of a Lambda lysogen and the induction of the SOS response [87][84], The bottlenose dolphins of John's Pass in Boca Ciega Bay, St. Petersburg, Florida, exhibit a rare form of self-decoration and social object use called grass-wearing. [162] In modern culture, pinnipeds are thought of as cute, playful and comical figures. This interdisciplinary field integrates several disciplines, including psychology, veterinary and human medicine, psychiatry, biology, chemistry, and physics. Describe the major events involved in the early formation of the nervous system, from the single cell stage to gastrulation to neural tube closure II, 438. For example, the destruction of the Southeast Asian rainforest is endangering mixed-species feeding flocks with members from the family Corvidae. Instead, ex situ conservation removes the species from its natural ecological contexts, preserving it under semi-isolated conditions whereby natural evolution and adaptation processes are either temporarily halted or altered by introducing the specimen to an unnatural habitat. During the sleeping cycle, they remain near the surface, swimming slowly or "logging", and occasionally closing one eye. Increased body weight in males increases the length of time they can fast due to the ample energy reserves stored in the blubber. Organize numerical data in a spreadsheet [55] Although pinnipeds have a fairly good sense of smell on land,[56] it is useless underwater as their nostrils are closed. [13] Phocids have thickened mastoids, enlarged entotympanic bones, everted pelvic bones and massive ankle bones. Describe the anatomy of protochordates (chephalochordates and urochordates) 1. 3. 2. White-throated magpie-jays are cooperatively-breeding corvids where the helpers are mostly female. 7. Despite farmers' efforts to rid themselves of corvid pests, their attempts have only expanded corvid territories, and strengthened their numbers.[19]. Sharks are hatched or born as juveniles, or smaller versions of the adult. Females have two mammary slits, each housing one nipple, one on each side of the genital slit. 5. Discuss why some pathogens can be used as potential bioterrorism agents based on virulence factors and growth capabilities Large sharks are another major predator of pinnipedsusually the great white shark but also the tiger shark and mako shark. Describe (one-locus models) of how natural selection, mutation, migration, genetic drift, and nonrandom mating affect the evolution of a population; estimate coefficient of inbreeding Introductory Biology II (3-3) Credit 4. As a whole, they mostly feed on fish and cephalopods, followed by crustaceans and bivalves, and then zooplankton and endothermic ("warm-blooded") prey like sea birds. They have streamlined bodies and four limbs that are modified into flippers. Describe the basic animal systems: nervous, digestive, reproductive, excretory, skeleto-muscular, respiratory, circulatory, endocrine Previously untrained muscles acquire newly formed nuclei by fusion of satellite cells preceding the hypertrophy. In the past, most studies used morphology to evaluate differences between and within species, but in the late 20th century, combining morphological and molecular genetics allowed much greater insight into this previously intractable problem. 4 Hours. Explain how animal diversity and evolution are dependent on genetic changes occurring within populations 2. These animals lack external ear flaps and are incapable of turning their hind-flippers forward, which makes them more cumbersome on land. [164] Seals have been kept in captivity since at least Ancient Rome and their trainability was noticed by Pliny the Elder. A recent study found high levels of cadmium and mercury in bottlenose dolphins from South Australia,[162] levels which were later found to be associated with kidney malformations, indicating possible health effects of high heavy metal concentrations in dolphins. If you were admitted to Texas A&M Biology for a BA in Biology prior to Fall 2020 please, This Degree plan applies to students beginning in Fall 2022 or later. 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. The IUCN declared it extinct in 1996. Other species protected are southern elephant seals, Ross seals and Antarctic fur seals. Define characters and character states and their phylogenetic implications In ecology, the population 1. 8. 2. [133] Targeting a single adult dolphin can be dangerous for a shark of similar size. [42] Pinnipeds have several adaptions for reducing drag. Credit 4. Explain how cytoskeletal dynamics contribute to cell structure, organization, and directed movement Examine the effector functions and killing mechanisms of CD8 T cells as part of specific immune responses against intracellular pathogens [9] Further inbreeding within the captive population may also increase the likelihood that deleterious alleles will be expressed due to increasing homozygosity within the population. [43] Fore-flipper movement is not continuous, and the animal glides between each stroke. 4. [48], Dolphins have sharp eyesight. (3-3). 214. When threatened by other adults or when pups try to suckle, females make a harsh, pulsed call. 11. Their mystacial vibrissae have ten times the innervation of terrestrial mammals, allowing them to effectively detect vibrations in the water. [35][40], The flukes (lobes of the tail) and dorsal fin are formed of dense connective tissue and do not contain bone or muscle. 1.

Bull sharks have also been documented to traverse ~108 miles (175 km) of rapids in the Rio San Juan leading up to Lake Nicaragua from the Caribbean Sea. There is no parental care after birth among viviparous sharks. The prefrontal and frontal cortices are also active during this stage due to the need for increased attention on the task being learned. Prerequisite: BIOL 454 or registration therein. Several species are known to migrate vast distances, particularly in response to extreme environmental changes, like El Nio or changes in ice cover. This family has the unique ability to elevate their internal body temperatures above that of their surrounding environment by the use of a highly-developed network of blood vessels that retain the heat produced by their muscles. Define mechanisms of antibiotic resistance The exact mechanism of motor memory consolidation within the brain is controversial.

Tools are engineered according to task, and apparently, also to learned preferences. 4. During the first period of resistance exercise, the authors identify significant adaptations in the human methylome, whereby over 9,000 CpG sites were reported as being significantly hypomethylated, with these adaptations being sustained during the subsequent period of physical in-activity. A receptor cell can respond to a single molecule of the pheromone called bombykol and 200 molecules can cause a behavioral response. Describe bone anatomy including the Action/Origin/Insertions (AOIs) of the major muscles Apply quantitative theory to test biological predictions. [53], The pinniped ear is adapted for hearing underwater, where it can hear sound frequencies at up to 70,000Hz. 5. Magpies have been observed taking part in elaborate grieving rituals, which have been likened to human funerals, including laying grass wreaths. [55] Youngsters of social corvid species undergo a series of tests, including aerobatic feats, before being accepted as a mate by the opposite sex. [21] Importantly, these participants adapted in an enhanced manner, whereby the amount of skeletal muscle mass gained was greater in the second period of muscle growth than the first, suggesting a muscle memory concept. Some models of cerebellar-dependent motor learning, in particular the Marr-Albus model, propose a single plasticity mechanism involving the cerebellar long-term depression (LTD) of the parallel fiber synapses onto Purkinje cells. They are commonly kept in captivity and are even sometimes trained to perform tricks and tasks. Examines how behavior contributes to survival and reproduction, and how evolutionary history and ecological circumstance interact to shape the expression of behavior; focus on integrative nature of behavior: how the interaction of evolutionary processes, mechanistic constraints, and ecological demands determine behavioral strategies. Describe general features of DNA structure Species that may be eligible for Case studies have provided some examples of how motor memory has been implemented in patients with brain damage. Northern elephant seals commonly dive 350650m (1,1502,130ft) for as long as 20minutes. 2. 2. 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. Blue jays, for example, are well known to attack anything that threatens their nest. This allows them to stay submerged for long periods of time while still having enough oxygen. Credit 1. Other lineages derived from these ancestors evolved into ecologically diverse, but often Australasian, groups. 1. Analyze the challenges involved in developing new antibiotics Describe the principle of diffusion/osmosis [91], Bottlenose dolphins have a lifespan of 40-60 years.

[49], The Eurasian magpie is the only non-mammal species known to be able to recognize itself in a mirror test,[50] although later research could not replicate this finding. Compare the non-vertebrate chordates in regard to their modes of feeding, motility, early development, and habitat The Welsh Dream of Rhonabwy illustrates well the association of ravens with war. He states dolphins and porpoises feed on different types of fish, thus food competition is an unlikely cause of the killings. 6. 8. Explain cell biology basics such as what the mitochondrion is and does, etc. However, upon secondary exposure to resistance exercise, a greater frequency of hypomethylated CpG sites was observed, where over 18,000 sites reported as being significantly hypomethylated. Bottlenose dolphins gained popularity from aquarium shows and television programs such as Flipper. Explain how genetic variation contributes to evolution Credit 4. The captive population consists of around 300 birds.[16]. Credit 3. The increase in available human food sources is contributing to population rises in some corvid species.[20]. [142], Vocalizations are particularly important during the breeding seasons. When participating in any sport, new motor skills and movement combinations are frequently being used and repeated. Compute and interpret the results of examples of the Hardy-Weinberg Theorem I, II, 285. Pinnipeds also have very muscular and vascularized irises.

Explain antigen- antibody interaction outcomes based on antigen structure 8. 2. The speartooth shark has been captured over ~60 miles (100 km) up the Adelaide River in Australia. 8. [51], In 2022, a study at the University of St Andrews in Scotland found that dolphins were able to identify their "friends" and family members by the taste of their urine in the water. The former behavior is typical when hunting non-schooling fish, slow-moving or immobile invertebrates or endothermic prey. [106] Some species are capable of inflicting damaging wounds on their attackers with their sharp caninesan adult walrus is capable of killing polar bears. Gillnetting and Seine netting is a significant cause of mortality in seals and other marine mammals. [10] The target population size is the number of individuals that are required to maintain appropriate levels of genetic diversity, which is generally considered to be 90% of the current genetic diversity after 100 years. The adaptations of the Lemon Shark are usually physically enduced. [116] These males cluster around females and try to attract them with elaborate courtship displays and vocalizations. [27][28] Solving these puzzles in an optimally efficient manner requires the cube to be manipulated according to a set of complex algorithms. Killer whale populations in New Zealand and Peru have been observed preying on bottlenose dolphins, but this seems rare,[133] and other orcas may swim with dolphins.
