Elephant in space and time
Article Abstract:
An approach to analyze the patterns of autocorrelation in animal movements that provides a detailed picture of seasonal variability in the scale and patterns of movement is presented. A combination of moving window Mantel correlograms, surface correlation and crosscorrelation analysis is used to investigate the scales and patterns of autocorrelation in the movements of three herds of elephants in northern Botswana.

Strategies for ecological extrapolation
Article Abstract:
A framework is developed to evaluate and compare three classes of approaches to the problem of spatial extrapolation. A discussion of the characteristics of ecological systems that require spatial approaches is provided along with a statistical evaluation of errors.

Modeling vertical beta-diversity in tropical butterfly communities
Article Abstract:
A study was conducted to assess three tropical butterfly data-sets for spatial structure in the vertical dimension. The results indicated that the vertical dimension is a major structural component in tropical forest butterfly communities.
