Effects of spatiotemporal scale on autocorrelation and home range estimators

Article Abstract:

There is increased interest in seeking an appropriate spatiotemporal scale when designing empirical ecological studies. Radiotelemetry has been the traditional technique for animal space use studies, but new computer intensive estimators have been developed. A study of root vole populations using Kernal, Cluster and MCP home range estimators found that the Kernal was robust to changes in spatial data resolution. It was also found that the degree of autocorrelation was sex specific. Schoener's ratio is considered a useful space use descriptor for wildlife biologists concerned with animal space use patterns.

The effect of scent marking, forest clearing, and supplemental feeding on moose-train collisions

Article Abstract:

The application of scent-marking, forest clearing, and supplemental feeding that correlated with the number of moose train collisions along the most vulnerable railroad stretch in Norway was analyzed. The findings suggested that mitigative efforts might substantially reduce accidental mortality in moose populations if applied in long distances.

Using scent-matching dogs to identify individual Amur tigers from scats

Article Abstract:

A study report suggest that scent-matching dogs trained to identify unique characteristics present in scat (fecal material, if used with mark-capture surveys to estimate species abundance have the potential to become an important tool to study wild Amur tigers as well as other wildlife species.
