Black Rhinoceros Order: Perissodactyla Family: Rhinocerotidae Genus: Diceros Species: bicornis Quick Facts About Black Rhinoceros The black rhinoceros (Diceros bicornis), is a species of rhinoceros.

There are four subspecies of the black rhinoceros, of which three are listed as critically endangered and one as probably extinct.

1 Black Rhinoceros Order: Perissodactyla Family: Rhinocerotidae Genus: Diceros Species: bicornis Quick Facts About Black Rhinoceros The black rhinoceros (Diceros bicornis), is a species of rhinoceros. The black rhinoceros, though referred to as black, is actually more of a grey/brown/white color in appearance. There are four subspecies of the black rhinoceros, of which three are listed as critically endangered and one as probably extinct. The black rhinoceros has a thick layered skin that protects it from thorns and sharp grass. Black rhinoceroses have relatively poor eyesight, and rely more on their sense of smell and hearing. Their ears possess a relatively wide rotational range to detect sounds and their keen sense of smell alerts them to the presence of predators. The black rhinoceros has been pushed to the brink of extinction by illegal poaching for their horns and by loss of habitat. The horns, used in traditional Chinese medicine, are considered by herbalists, to be able to revive comatose patients, cure fevers, and aid male sexual stamina and fertility. This has not been verified by medical science. In the Middle East, the horn of the Black Rhinoceros is used to make ornately carved handles for ceremonial daggers called jambiyas. Demand for these daggers, has been the cause of decline of the Black Rhinoceros population by 96%, between 1970 and Black Rhinoceros Case Study You are a wildlife biologist researching black rhinos. During your time in Africa, you have observed two particular traits that allow some black rhinos to be better adapted to their environment. The first trait is an extra-long prehensile lip that enables the rhino to have more efficient browsing capability than the usual size prehensile lip. Second, some of the rhinos in the study have extra-long ears that allow them to hear a potential predator earlier than rhinos with normal size ears. If you could breed black rhinos that have both these traits (extra-long prehensile lip and bigger ears), it would increase their chance for survival in the wild. You have chosen the following two rhinos to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Homozygous dominant for the prehensile lip trait (PP). Thus, this parent does not express the extra-long lip trait. Heterozygous for the longer ear trait (Ee). Thus, this parent does not express the extra-large ear trait. Heterozygous for the prehensile lip trait (Pp). Thus, this parent does not express the extra-long lip trait. Homozygous recessive for the large eared trait (ee). Therefore, the parent does express the extra-long ear trait.

Burmese Python Class: Reptilia Order: Squamata Family: Pythonidae Genus: Python Species: bivittatus Quick Facts About Burmese Pythons Burmese pythons, with their beautifully patterned skin, rapid

Unfortunately these potentially huge constrictors are often poorly cared for and are frequently released into the wild.

2 Burmese Python Class: Reptilia Order: Squamata Family: Pythonidae Genus: Python Species: bivittatus Quick Facts About Burmese Pythons Burmese pythons, with their beautifully patterned skin, rapid growth rate, and generally docile disposition, may be best known as the large snake of choice among reptile owners. Unfortunately these potentially huge constrictors are often poorly cared for and are frequently released into the wild. Native to the jungles and grassy marshes of Southeast Asia, Burmese pythons are among the largest snakes on Earth. They are capable of reaching 23 feet or more in length and weighing up to 200 pounds. Burmese pythons are carnivores, surviving primarily on small mammals and birds. They have poor eyesight, and stalk prey using chemical receptors in their tongues and heat-sensors along the jaws. They kill by constriction, grasping a victim with their sharp teeth, coiling their bodies around the animal, and squeezing until it suffocates. Burmese pythons are solitary animals and are generally only seen together during spring mating. Females lay clutches of up to 100 eggs, which they incubate for two to three months. To keep their eggs warm, they continually contract, or shiver, their muscles. Habitat depletion, continued demand for Burmese pythons in the pet trade, and hunting for their skins and flesh have landed these graceful giants on the threatened species list. Burmese Python Case Study You are a wildlife biologist researching Burmese pythons. During your time in Asia, you observed a particular trait that allows some Burmese pythons to be better adapted to their environment. Some snakes have extralarge scales on their abdomen. This increases the surface area of their abdomen that is in contact with the ground, therefore, making locomotion easier. In addition, you noticed that albino Burmese pythons do not survive as long in the wild as those who have normal pigmentation because lack of camouflage ability (beige blotches on a dark brown background). If you could breed Burmese pythons that have normal pigmentation (avoiding albinism) and extra-large abdominal scales, it would increase their chance for survival in the wild. You have chosen the following two Burmese pythons to enter into a breeding program for the two desired phenotypic traits. It has been determined that the trait for the extra-large abdominal scales is homozygous recessive. Albinism is also a homozygous recessive trait. The normal pigmentation trait is dominant and is expressed in homozygous dominant and heterozygous individuals. Heterozygous for the extra-large ventral (abdomen) scales (Ss). Therefore this parent does not express the extra large scale trait. Heterozygous for the pigmentation trait (Pp). Thus, this parent expresses the normal pigmentation. Heterozygous for the extra-large ventral (abdomen) scales (Ss). Therefore this parent does not express the extra large scale trait. Heterozygous for the pigmentation trait (Pp). Thus, this parent expresses the normal pigmentation.

Bald Eagle Class: Aves Quick Facts About Bald Eagles Order: Falconiformes The bald eagle is not really bald; it actually has white feathers on its head, neck, and tail.

Bald eagles can actually swim! They use an overhand movement of the wings Species: that is very leucocephalus much like the butterfly stroke.

3 Bald Eagle Class: Aves Quick Facts About Bald Eagles Order: Falconiformes The bald eagle is not really bald; it actually has white feathers on its head, neck, and tail. Family: Bald is Accipitridae a deviation of balde, an Old English word meaning white. The eagle was named for its white feathers Genus: instead Haliaeetus of a lack of feathers. Bald eagles can actually swim! They use an overhand movement of the wings Species: that is very leucocephalus much like the butterfly stroke. This skillful hunter is aided by a few key adaptations including oily plumage, big feet, a large curved beak, and a reversible toe which allows them to carry sizeable fish while in flight. Also, rough sandpaper-like spicules on the bottoms of its feet allow the bald eagle a good grip on slippery prey. In the mid-20th century bald eagles declined in numbers, due mainly to the indiscriminate use of pesticides. Since 1972, with the banning of DDT and many other harmful chemicals, bald eagle numbers have greatly increased. Now the number of bald eagles has increased so much that in June 1994, the U.S. Fish and Wildlife Service proposed that they be downgraded from endangered status to the less urgent status of threatened in all but three of the lower 48 states. The success of the bald eagle is a tribute to the Endangered Species Act and is an incentive for increased awareness and conservation everywhere. Bald Eagle Case Study You are a wildlife biologist researching ospreys. During your time in North America, you have observed two particular traits that allow some bald eagles to be better adapted to their environment. The first trait is a bony overhang above their eyes. This overhang protects the eyes from the sun and shades the bird's eyes from any glare and enables it to see into the water more easily while searching for fish. Second, some of the bald eagles in the study have extra-long spicules, or bump on their feet, than others. The bald eagles that have these extra-long spicules are able to capture fish more efficiently than those who do not have the extra-long spicules. If you could breed bald eagles that have both these traits (extra-large bony overhang and longer spicules), it would increase their chance for survival in the wild. You have chosen the following two bald eagles to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Heterozygous dominant for the extra-large bony overhang trait (Pp). Therefore this parent does not express the extra-large bony overhang trait. Homozygous recessive for the extra-long spicule trait (ss). Therefore this parent does express the extra-long spicule trait. Homozygous recessive for the extra-large bony overhang trait (pp). Therefore this parent does express the extra-large bony overhang trait. Heterozygous dominant for the extra-long spicule trait (Ss). Thus the parent does not express the extralong spicule trait.

Prehensile-tailed Porcupine Order: Rodentia Family: Erethizontidae Genus: Coendou Species: prehensilis Quick Facts About Prehensile-Tailed Porcupines Prehensile-tailed porcupines range in color from

Their long tails are also quilled, but have bare tips for better grip. Both hind- and forefeet have four digits with long curved claws for climbing.

4 Prehensile-tailed Porcupine Order: Rodentia Family: Erethizontidae Genus: Coendou Species: prehensilis Quick Facts About Prehensile-Tailed Porcupines Prehensile-tailed porcupines range in color from brownish-yellow to nearly black. Their bodies are about 18 inches long and are covered with thick, sharp quills, which are longer and lighter in color than their fur. Their long tails are also quilled, but have bare tips for better grip. Both hind- and forefeet have four digits with long curved claws for climbing. They have a bald, bulbous nose which aids their excellent sense of smell; however, they have poor vision. Prehensile-tailed porcupines are arboreal, spending most of their time climbing among the treetops in their forest homes. They are nocturnal, spending their days sleeping in hollows or tangled vines high above the forest floor, awakening at night to forage. They rarely drink water, but obtain all they need from their diet. When confronted, they may stomp their feet and shake their quills, making a rattling noise. Like all porcupines, their barbed quills are not thrown or shot at predators, but release quite easily when the porcupine is tense. Prehensile-tailed porcupines are in danger from habitat destruction. The forests where they live are being cleared to provide land for agriculture and urban growth. What you buy can help protect forest habitat. Buy wood products that are sustainably harvested, coffee which is shade-grown, and produce grown locally to you. Prehensile-tailed Porcupine Case Study You are a wildlife biologist researching prehensile-tailed porcupines. During your time in South America, you have observed two particular traits that allow some porcupines to be better adapted to their environment. The first trait is an extra-long prehensile tail that enables the porcupine to have more efficient grasping capabilities than the usual length prehensile tail. Second, some of the porcupines in the study have extralong whiskers on their face and feet that allow them to sense their environment better than those that have normal size whiskers. If you could breed prehensile-tailed porcupines that have both these traits (extra-long prehensile tail and whiskers), it would increase their chance for survival in the wild. You have chosen the following two porcupines to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Heterozygous for the extra-long prehensile tail trait (Tt). Therefore this parent does not express the extra-long tail trait. Heterozygous for the extra-long whisker trait (Ww). Therefore this parent does not express the extralong whisker trait. Heterozygous for the extra-long prehensile tail trait (Tt). Therefore this parent does not express the extra-long tail trait. Heterozygous for the extra-long whisker trait (Ww). Therefore this parent does not express the extralong whisker trait.

Lesser Long-eared Bat Quick Facts About Long-eared Bats This species is a highly adaptable bat and as a result is one of the most widespread bats that are endemic to Australia.

These bats are usually nocturnal, living in dark caves, hollows, old trees, ceilings and hollow walls.

5 Lesser Long-eared Bat Quick Facts About Long-eared Bats This species is a highly adaptable bat and as a result is one of the most widespread bats that are endemic to Australia. It lives in deserts, tropical to alpine woodlands, mangroves, agricultural land, urban areas, wet to dry forests and rain forests. These bats are usually nocturnal, living in dark caves, hollows, old trees, ceilings and hollow walls. Light grey colored fur is located on the back of the bat with noticeably lighter to white fur on its underbelly, these hairs range from dark at the base to light at the ends. The distinguishing feature of this species is the high nose ridge split and their large ears. When flying this species will point the tips of its ears forward listening for sound emitted from small openings located at the top of their snouts. Grasshoppers, crickets and moths are their most common food but have a large variety of foods including: lacewings, beetles, flies, cricket nymphs, cockroaches and spiders. Lesser Long-eared Bats are vulnerable to loss of tree hollows and loss of feeding grounds by forestry activities, clearing for agriculture and housing, and land degradation. Order: Chiroptera Family: Pteropodidae Genus: Pteropus Species: macrotis Long-eared Bats Case Study You are a wildlife biologist researching long-eared bats. During your time in Australia, you have observed two particular traits that allow some long-eared bats to be better adapted to their environment. The first trait is extra-large ears that enables the bat to echolocate and find food more effectively than the usual size ears. Second, some of the bats in the study have stronger tendons in their feet than others. The bats that have stronger tendons are able to hang upside from branches longer than those who do not have as strong of tendons. If you could breed long-eared bats that have both these traits (stronger tendons and larger ears), it would increase their chance for survival in the wild. You have chosen the following two bats to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Heterozygous dominant for the extra-large ear trait (Nn). Therefore this parent does not express the extra-large ear trait. Homozygous recessive for the extra strong tendon trait (tt). Therefore this parent does express the extra strong tendon trait. Homozygous recessive for the extra-large ear (nn). Therefore this parent does express the extra-large ear trait. Homozygous recessive for the extra strong tendon trait (tt). Therefore the parent does express the extra strong tendon trait.

European Bison Order: Artiodactyla Family: Bovidae Genus: Bison Species: bonasus Quick Facts About European Bison European bison are the largest native herbivores in Europe.

6 European Bison Order: Artiodactyla Family: Bovidae Genus: Bison Species: bonasus Quick Facts About European Bison European bison are the largest native herbivores in Europe. Their appearance is very similar to North American bison although they are smaller in stature and have a longer mane on the forehead and beneath the neck. The coat is also less shaggy than American bison and varies in color from golden brown to dark brown. Their head is set at a slightly higher angle than the American Bison, and this means they tend to browse more from slightly higher foliage, and graze less from ground-level grasses. European Bison used to inhabit temperate, coniferous forests in much of Europe. However for centuries their numbers have dwindled as they were hunted and driven out of their natural habitat due to forestry and farming. Slowly the European Bison was eradicated from countries across Europe and in 1927 the last wild European Bison was killed by poachers in southern Russia. In that year fewer than 50 European Bison existed, all of them in zoos. Wild populations existing today were reintroduced using these 50 animals in a breeding program. European Bison can now be found in nature reserves in Poland, Lithuania, Belarus, Ukraine, Romania, Russia, Slovakia, Latvia, Kyrgyzstan, Moldova and Spain. European Bison Case Study You are a wildlife biologist researching European bison. During your time in Europe, you have observed two particular traits that allow some European bison to be better adapted to their environment. The first trait is that some European bison have thicker horns than others. The thick horns enable the European bison to defend itself better than European bison that do not have the thicker horns. Second, some of the European bison in the study have longer prehensile tongues than others. The European bison that have this extra-long prehensile tongue are able to browse for food more efficiently than those who do not have this trait. If you could breed European bison that have both these traits (thicker horns and longer prehensile tongues), it would increase their chance for survival in the wild. You have chosen the following two European bison to enter into a breeding program for the two desired phenotypic traits. It has been determined (based on your previous research) that both the desired traits are homozygous recessive. Heterozygous dominant for the horn trait (Hh). Therefore this parent does not express the extra thick horn trait. Heterozygous dominant for the prehensile tongue trait (Ll). Therefore this parent does not express Heterozygous dominant for the horn trait (Hh). Therefore this parent does not express the extra thick horn trait. Heterozygous dominant for the prehensile tongue trait (Ll). Therefore the parent does not express
