Textbook Question
Chapter 43.2, Problem 3CC
WHAT IF? In 2005, at least ten grizzly bears in the greater Yellowstone ecosystem were killed through contact with people. Most of these deaths resulted from three things: collisions with automobiles, hunters (of other animals) shooting when charged by a female grizzly bear with cubs nearby, and conservation managers killing bears that attacked livestock repeatedly. If you were a conservation manager, what steps might you take to minimize such encounters in Yellowstone?

Domino Effects As we’ve learned, species are not islands unto themselves; they are integrated with many other organisms in trophic relationships, mutualisms, competition, etc. How is the absence of this species (or its lowered population size) likely to impact the other members of its habitat? (If findings specific to this point are available, please include them – otherwise, I’m asking you to speculate based on what you’ve learned about the biology of this organism.)
Conservation Efforts Discuss past, current, and proposed efforts to conserve this species. Are these strategies effective? Are they realistic? What is the outlook for this organism?
Match the approach to protection with the example from the academic literature.
Species approach
Hotspot approach
Ecosystem approach
1.
Wolf reintroductions into the Yellowstone environment restored riparian species and increased biodiversity because wolves controlled the numbers of elk and coyotes which allowed plants, beaver, and foxes to rebound (Ripple and Beschta 2003).
2.
The creation of a reserve protects the red-brown treecreeper (Climacteris picumnus). This approach looks to accommodate processes that threaten species viability, such as fragmentation and feral predators (Nicholson et al. 2013).
3.
Species richness of tiger beetles, Cicindelidae, is positively correlated with bird and butterfly diversity across North America, Australia, and the Indian subcontinent (Reid, 1998).
Which one of these statements about COSEWIC is false?
COSEWIC's assessments take into account political, social and economic factors.
The Species at Risk Act (2002) established COSEWIC as an advisory body.
The committee made its first designation in April 1978 and has met annually since then.
Members of COSEWIC are wildlife biology experts from academia, government, non-governmental organizations and the private sector responsible for designating wildlife species in danger of disappearing from Canada.

- Conservation Biology Quiz 2 4. Predator- predator inter a prey h Conservation Biology Quiz 2 2. Community - Competition. Competition between species on the same trophic tier leads to four potential outcomes, 3 are deterministic (zero sum games where one species goes extinct and the other maximizes their growth to balance at the carrying capacity) and one where both competitors survive, but neither does well. a. This dynamic suggests that extirpation (local extinction) of populations is a far more likely outcome than co-existence. How, in your opinion, does this affect management policies aimed at increasing biodiversity and proliferation of inter and intra population and interspecies variation. Reason your point of view.

The decline or extinction of a single species can also change the composition of other species within a habitat, including a shift in species dominance or decrease in the survival ability of the remaining species. Other problems can occur when overexploitation leads to a drop in nearby populations. For instance, when overfishing of one species leads to a decline in by-catch or drives the market to overexploit another, previously unexploited, species. The most overexploited groups of species are marine fish and invertebrates (which are fished for food), a variety of trees, animals hunted for meat, and plants and animals harvested for medicinal use and trading.
