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.

The only mode of transportation available is by boat or seaplane. Moose first arrived at Isle Royale around 1900. The moose population tends to increase in years with mild winters, early spring green-up, abundant winter forage, low wolf numbers and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from Canada in 1940. Disease has also influenced the wolf population. Between 1980 and 1982, the wolf population declined from 50 to 14, due to canine parvovirus.

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?arrow_forward

Which of the following is a likely effect of the paper mill's sustainable waste management protocols? Choose 1 answer: The chemical waste will have to be dumped in a different river, likely affecting fish and invertebrate populations in that ecosystem. The river will be more hospitable to fish, helping increase biodiversity within the river's fish populations. The paper mill will go out of business due to the extra costs of waste management.
