Allegheny woodrat (neotoma magister) populations in the northern and western limits of the range have been greatly reduced in recent years, increasing the need to locate and monitor both threatened and seemingly stable populations. We tested the feasibility of predicting areas of suitable habitat for the woodrat in the Daniel Boone National Forest (DBNF) by using a Geographic Information System model. Several themes depicting woodrat habitat variables were overlaid to produce a comprehensive map displaying likelihood of woodrat occurrence. Logistic regression analysis was used to determine...

A stochastic computer model was written to simulate the dynamics of red fox (Vulpes vulpes) populations in Kentucky. The model consists of the main module equations and 2 submodules: ASMOSU and BIRTH. Main module equations calculate the number and density of individuals in each age class and the total population. ASMOSU calculates all total and age specific mortality rates. BIRTH calculates the number of individuals recruited into the 0.5-year age class. The model is useful for evaluating scenarios for red fox management in Kentucky because, except for minor exceptions, it validly...
