What species is targeted for conservation? What are their primary social behaviors (Group size, lifestyle, foraging habits and diet, hierarchies, territorial habits)? Where are they located and what are potential human influences on their habitats? What are the specific conservation strategies proposed in the report? How do they make use of new technologies (like GPS tracking, drone survey etc if applicable)? Do you think the strategies are appropriate given the particular social behaviors of that species? Do the strategies appropriately address the needs of this species as well as local community well-being and the political context?
What do restocking programs for wild animals involve?
Pick one of the following answers:
Releasing individuals into an existing population to increase the size of the population and the diversity of its gene pool
Releasing wild-collected individuals into a new site
Releasing captive-bred individuals into a new site
Releasing captive-bred or wild-collected individuals into an ecologically suitable site within their historical ranges where the species no longer occurs

- You are a population ecologist studying animals in a national park, and park managers are asking for advice on how to focus their limited conservation funds. How would you rate the following three species, from most vulnerable (and thus most in need of conservation attention) to least vulnerable? Give reasons for your choices. • A bird that is a generalist in its use of habitats and resources • A salamander endemic to the park that lives in highelevation forest • A fish that specializes on a few types of invertebrate prey and has a large population sizearrow_forwardWhat are important characteristics of adequate monitoring plans for translocation programs? Select all the correct options. Select 3 correct answer(s) Leaving released individuals aside and focusing on monitoring the population as a whole. Avoid advertising the success of program to local communities so that released individuals are not bothered by curious people. A long-term plan that involves monitoring the population over many years. Monitoring the costs of the program so that cost-effective analysis can be made. Monitoring other ecosystem elements beyond the released species, such as prey and vegetation.arrow_forwardWhich of the following is true with regards to establishment programs? Which of the following is true? Success was greater in the periphery and outside of the historical range than in the core Success was greater in depauperate habitats than in species rich habitats Success was greater for captive-reared than with wild-caught Success was greater for herbivores than carnivoresarrow_forward
- 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.arrow_forwardGive the Major Assumption/s of the following theories: Conservation Model Artinian Intersystem Model Modeling and Role Modeling Theory Theory of Goal Attainment Theory of Human Caringarrow_forwardDiscuss what effective population size (Ne) is , and why is it of importance for conservation strategies .

- Conservation biologists working with the Florida panther have set out camera traps to estimate the overall population. Through a combination of live trapping and hair snares, the biologists have worked out the exact genetics for two alleles in all remaining individuals. The homozygous recessive state causes a debilitating disease and the panthers die before reproducing. Biologists have found a high incidence of heterozygous individuals. Help the biologists determine the best conservation action in order to protect and boost the genetic health of the remaining population. The current population of Florida panthers in this example is twenty which is based upon available habitat. Eighteen of the panthers are heterozygous [Aa]. Scientists have determined that eighteen is the minimum viable population for the Florida panthers. If eighteen of the panthers are heterozygous and if homozygous recessive individuals die before reproducing, what is the genotype for the remaining two…arrow_forwardWhat are the implications of the "bottleneck effect" for wildlife managers who try to help endangered species, such as the whooping crane, recover from near extinction?arrow_forwardConservation biologists working with the Florida panther have set out camera traps to estimate the overall population.

Consider the resources related to tracking methods and discuss the benefits of this kind of research in understanding and protecting wildlife populations.
