Demographics of an ornate box turtle population experiencing minimal human-induced disturbances
Article Abstract:
Examination of ornate box turtles in western Nebraska with reference to their survival rates and population growth rates from 1981-2000 based on mark-recapture data is discussed. Stochastic simulations show that mean and temporal process variance would result in a 58% probability of a population decrease during a 20-year period.

An evaluation of weather and disease as causes of decline in two populations of boreal toads
Article Abstract:
An 11-year capture-recapture data set was used to evaluate weather and disease as causes of decline of boreal toads. Results suggest a strong, negative 'marking effect' on survival rates of boreal toads.
