Population estimation and biases in paintball, mark-resight surveys of elk

Article Abstract:

The potential biases of paintball, mark-resight surveys of elk are explored along with alternative methods that could be used to generate population estimates from mark-resight such as like Bailey's binomial MLE-, cluster sampling and bootstrap methods. Results show that population estimates would generally be negatively biased, with the magnitude of the bias depended upon the degree of herd aggregation and fidelity.

Using time series to estimate rates of population change from abundance data

Article Abstract:

A technique is proposed to evaluate the finite rate of population increase and its related variance when observations are related over time through a simple time series method. The process using a spectacled eider (Somateria fischeri) data set of predicted yearly abundances and the analytic variance estimator gives a plan to decide future analysis to minimize uncertainty and bias in assessments.

Modeling black-tailed deer population dynamics using structured and unstructured approaches

Article Abstract:

Reconstructed population estimates and age class representations are used to analyze relationships between population change of Columbian black-tailed deer and female density, forage availability, weather influences. The structured and unstructured models could help in the prediction of the deer population change.
