Relative Contributions of Sampling Error in Initial Population Size and Vital Rates to Outcomes of Population Viability Analysis

Article Abstract:

Research demonstrates the effects of sampling error in initial survival and reproduction rates on simulated population viability analysis outcomes, using grizzly bears as an illustration. Sampling error can render resulting population persistence estimates inaccurate and unusable for wildlife management planning.

Survival and body condition of raccoons at the edge of the range

Article Abstract:

A study was conducted to ascertain the survival and body condition of raccoons during winter relevant to availability of food sources. Results revealed that there was no significant change in the body conditions of raccoons after winter indicating reliable availability of food sources.
