Question
1. Clearly, this population is in trouble, and the US Fish and Wildlife Service (FWS) needs guidance from a population ecologist. They contact you to seek advice on the life-history parameters to target and possible management strategies
a. Perform all necessary analyses for you make management recommendations (they wouldn’t know what to do – that’s why they are consulting you!
b. Make specific management suggestions regarding which life-history variables management should target. You must explain/justify your recommendations to FWS in plain language (they don’t care about mathematical details but they know the squirrels).
c. Make recommendations on specific management actions that would make 4.b happen – and may possible reverse the population declines. Again, you must provide clear guidelines and rationale/justification for you recommendations and guidelines.
Explanation / Answer
Ans 1. ( 1) As, population is in trouble the following recommendation should be follow to manage the fish and wild life survival.
Ans 1(2)
To understand the evolutionary processes and conservation management- rate of random genetic drift and effectiveness of natural selection has to be studied, which is influenced by the effective population size (Ne). Life history factors influenced by the ratio of Ne to census size (N), with the goal to identify the species for which demographic information is not available. But most of the species do not have constant vital rates, and life traits are correlated and they do not vary independently.
Empirical approach to calculate the relationship between species life history traits and the key effective ratio can be calculated by: Nb/Ne, Ne/N and Nb/N

To manage the large wildlife conservation program information of each species should be strategically allocated. Conservation status mainly comprises of two components- status of threat of species and the demographic status of species.U.S. Fish and Wildlife Service (FWS) administers strategize information and consistent metric to evaluate the conservation status of species and this has been divided in mainly three ways – Simplicity, Sufficiency and Consistency. The metrics masks the underlying demographic declines and increase of threat can be calculated by the scoring keys which can be applied to substantial set of species to understand the patterns of ESA. The scoring repeat analysis indicates the threat and demographic score. This program helps the administrators to monitor program efficiently and guide their decisions.
