Which of the following is not a part of the red list criteria for "critically endangered" species? The population is expected to decline by 25% or more within 3 years or 1 generation. The species has a restricted range <100km2 at a single location and there is observed or predictive habitat loss, fragmentation, ecological imbalance or heavy commercial pollution. Extinction probably is greater than 50% within 10 years or 3 generations. The total population size is less than 200 mature individuals.
Match the following species status to these species in Canada. Endangered Extirpated Special Concern Threatened Extinct Not at risk 1. American Badger (Taxidea taxus jacksoni) 2. Bear's-foot Sanicle (Sanicula arctopoides) 3. Rocky Mountain Sculpin (Cottus sp.) Westslope populations 4. Eelgrass Limpet (Lottia alveus alveus) 5. Four-toed Salamander (Hemidactylium scutatum) 6. Frosted Elfin (Callophrys irus)
Please help me answer this in 10 sentences only. In the Convention of Biological Diversity (CBD), the precautionary principle read “when there is a threat of significant reduction or loss of biological diversity, lack of full scientific uncertainty should not be used as a reason for postponing measure to minimize or avoid threat”. What is the application of this principle to straddling fish stocks and migratory fishes? Thank you very much for your help
ENDANGERED ANIMAL is CA least tern bird 1-3 bases on the bird Reasons for Endangerment Explain the various factors that have led to this species’ current plight. Expand on these points individually, based on your species’ unique story. 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?

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.
Read the article given below and answer the questions that follow: Recent increases in populations of seabirds that were depleted severely during the middle of the twentieth century demonstrate the efficacy of conservation strategies that work within the context of local culture. Along the North Shore of the Gulf of St. Lawrence in Quebec, Canada, direct exploitation and disturbance of breeding seabirds caused severe declines for several species between 1955 and 1978, including 84 percent and 76 percent declines for Razorbill and Atlantic Puffin, respectively. Significant reductions also occurred for populations of Common Eider (Somateria molissima), Common Murre (Uria aalge), and Black Guillemot (Cyphus grylle). Research by the Quebec-Labrador Foundation, a nonprofit conservation organization, into root causes of the population declines along a 400-km stretch of coast revealed conflicts between conventional enforcement of migratory bird regulations and cultural norms. A household…

Which of the subsequent options is not included in the red list criteria for species classified as "critically endangered"? 1. The population is projected to decrease by 25% or more within a span of 3 years or 1 generation. 2. The species possesses a limited range of less than 100km2 in a solitary location, and there is evidence of or anticipated habitat loss, fragmentation, ecological imbalance, or significant commercial pollution. 3. The likelihood of extinction exceeds 50% within a timeframe of 10 years or 3 generations. 4. The overall population size consists of fewer than 200 mature individuals.
