Baby Giraffe Rope-Pulled out of Mother Suffering from Dystocia Without Proper Restraint Device
J Vet Clin 26(1) : 113-116 (2009) Baby Giraffe Rope-Pulled Out of Mother Suffering from Dystocia without Proper Restraint Device Hwan-Yul Yong1, Suk-Hyun Park, Myoung-Keun Choi, So-Young Jung, Dae-Chang Ku, Jong-Tae Yoo, Mi-Jin Yoo, Mi-Hyun Yoo, Kyung-Yeon Eo, Yong-Gu Yeo, Shin-Keun Kang and Heon-Youl Kim Seoul Zoo, Gwacheon 427-080, Korea (Accepted : January 28, 2009 ) Abstract : A 4-year-old female reticulated giraffe (Giraffa camelopardalis reticulata), at Seoul Zoo, Gwacheon, Korea had a male calf with no help of proper restraint devices. The mother giraffe was in a danger of dystocia more than 7 hours in labor after showing the calf’s toe of the foreleg which protruded from her vulva. After tugging with a snare of rope on the metacarpal bone of the calf and pulling it, the other toe emerged. Finally, with two snares around each of metacarpal bones, the calf was completely pulled out by zoo staff. After parturition, the dam was in normal condition for taking care of the calf and her progesterone hormone had also dropped down to a normal pre-pregnancy.

Grizzly Bear Fact Sheet
Identify Grizzly from Black Bears Grizzly bears typically weigh 100-200 kg (females) to 200-300 kg (males) which is slightly more than black bears. Grizzly bears have a shoulder hump, range in colour from blonde to black and may have silver or light- tipped guard hairs on their head, hump and back. A grizzly bear’s ears are rounded and appear smaller than the black bear, while the black bear has more pointed, noticeable ears and no shoulder hump. Grizzly bear claws are longer than those of black bears and may have a light-coloured stripe.

Wetlands Invertebrates Banded Woollybear(Isabella Tiger Moth Larva)
Wetlands Invertebrates Banded Woollybear (Isabella Tiger Moth larva) basics The banded woollybear gets its name for two reasons: its furry appearance and the fact that, like a bear, it hibernates during the winter. Woollybears are the caterpillar stage of medium sized moths known as tiger moths. This family of moths rivals butterflies in beauty and grace. There are approximately 260 species of tiger moths in North America. Though the best-known woollybear is the banded woollybear, there are at least 8 woollybear species in the U.S. with similar dense, bristly hair covering their bodies. Woollybears are most commonly seen in the autumn, when they are just about finished with feeding for the year. It is at this time that they seek out a place to spend the winter in hibernation. They have been eating various green plants since June or early July to gather enough energy for their eventual transformation into butterflies. A full-grown banded woollybear caterpillar is nearly two inches long and covered with tubercles from which arise stiff hairs of about equal length. Its body has 13 segments. Middle segments are covered with red-orange hairs and the anterior and posterior ends with black hairs. The orange-colored oblongs visible between the tufts of setae (bristly hairs) are spiracles—entrances to the respiratory system. Hair color and band width are highly variable; often as the caterpillar matures, black hairs (especially at the posterior end) are replaced with orange hairs. In general, older caterpillars have more black than young ones. However, caterpillars that fed and grew in an area where the fall weather was wetter tend to have more black hair than caterpillars from dry areas. -

How People Should Respond When Encountering a Large Carnivore: Opinions of Wildlife Professionals Dy L a N E
Human–Wildlife Conflicts 2(2):194–199, Fall 2008 How people should respond when encountering a large carnivore: opinions of wildlife professionals DYLA N E. BRO wn , 507 Silo Loop, Kinsey, Montana 59338, USA [email protected] MI C HAEL R. CO N OVER , Jack H. Berryman Institute, Department of Wildland Resources, Utah State University, Logan, Utah 84322-5230, USA Abstract: We conducted telephone surveys of wildlife professionals who work with large carnivores to ask their opinions about how people should respond to avoid being injured when confronted by a black bear (Ursus americana), grizzly bear (Ursus arctos), mountain lion (Puma concolor), or gray wolf (Canis lupus). The respondents agreed that the most appropriate response was to try to increase the distance between a person and the carnivore. In the event of an attack by a black bear, mountain lion, or wolf, most respondents said to fight back. Opinion was divided over the best response for an individual who was being attacked by a grizzly bear, but a slight majority of professionals said to fight back if the attack was predatory and be passive if the attack was defensive; however, respondents also noted that many victims would be unable to identify the bear’s motive. If a black bear came into camp, most respondents said that a person should aggressively encourage the bear to leave and to fight back against a bear that enters a tent at night, regardless of species. Respondents unanimously agreed that bear pepper-spray is effective in defending against an attack. While any encounter with a large carnivore can be fatal to the person involved, we believe that selecting the right course of action increases the odds that the victim can escape without injury. -
Periodic Status Review for the Steller Sea Lion
STATE OF WASHINGTON January 2015 Periodic Status Review for the Steller Sea Lion Gary J. Wiles The Washington Department of Fish and Wildlife maintains a list of endangered, threatened, and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011, Appendix E). In 1990, the Washington Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297, Appendix A). The procedures include how species listings will be initiated, criteria for listing and delisting, a requirement for public review, the development of recovery or management plans, and the periodic review of listed species. The Washington Department of Fish and Wildlife is directed to conduct reviews of each endangered, threatened, or sensitive wildlife species at least every five years after the date of its listing. The reviews are designed to include an update of the species status report to determine whether the status of the species warrants its current listing status or deserves reclassification. The agency notifies the general public and specific parties who have expressed their interest to the Department of the periodic status review at least one year prior to the five-year period so that they may submit new scientific data to be included in the review. The agency notifies the public of its recommendation at least 30 days prior to presenting the findings to the Fish and Wildlife Commission. In addition, if the agency determines that new information suggests that the classification of a species should be changed from its present state, the agency prepares documents to determine the environmental consequences of adopting the recommendations pursuant to requirements of the State Environmental Policy Act. -

The Effects of the Lake Trout Introduction in Yellowstone Lake on Populations Outside the Aquatic a Meta-Analytic Study
Migrate, Mutate, or Die: The effects of the lake trout introduction in Yellowstone Lake on populations outside the aquatic A Meta-Analytic Study By Sarah Z. Gandhi-Besbes University of Colorado at Boulder A thesis submitted to the University of Colorado at Boulder in partial fulfilment of the requirements to receive Honours designation in Environmental Studies May 2016 Thesis Advisors: Alexander Cruz, Ecology and Evolutionary Biology, Committee Chair Dale Miller, Environmental Studies Andrew Martin, Ecology and Evolutionary Biology © 2016 by Sarah Z. Gandhi-Besbes All rights reserved i Abstract Yellowstone National Park is a relatively pristine ecosystem preserved through time. The Yellowstone cutthroat trout Oncorhynchus clarkii bouvieri population, inhabiting shallower waters in Yellowstone Lake and spawning in its tributaries, has been declining primarily due to the introduction of a predatory fish. The lake trout Salvelinus namaycush, which rapidly grow to large sizes, feed on the Yellowstone cutthroat trout, breed and spawn in Yellowstone Lake, and dwell in deeper waters out of predatory reach. The Yellowstone cutthroat trout is relied upon both directly and indirectly by more than 40 species within Yellowstone National Park. The grizzly bear Ursus arctos horribilis, bald eagle Haliaeetus leucocephalus, and osprey Pandion halaetus all feed directly on the spawning fish. This study looks at how the declining Yellowstone cutthroat trout populations affect these predatory populations, and what their populations may look like should current trends continue into the year 2030. Conducting a meta-analysis and collecting primary data allowed for statistical projections predicting and comparing estimated future populations. The ecological change in Yellowstone Lake provides insight into how the concerns of one ecosystem affects multiple.
