Effects of violation of assumptions for survival analysis methods in radiotelemetry studies
Article Abstract:
There are two important methods generally used in telemetry studies to assess survival. They are the Kaplan-Meier approach and the Trent and Rongstad approach. The impact of violation of assumptions has yet to be examined fully, and a brief evaluation has been carried out. The assumption that dead and live animals have equal censoring rates has been evaluated using a simulation, with the finding of large biases as a result of violations. Violation of the constant survival rate assumption in the Trent-Rongstadt approach have also been examined.

Global conservation priorities
Article Abstract:
Establishing priorities in conservation biology will help to concentrate efforts to better apply resources to endangered habitats. The hotspots model and the major tropical wilderness approach have been useful in focusing efforts of nongovernmental organizations and donors. Priority-setting exercises must not only tell conservationists what to save first, but how to save it.

Clearcuts, salamanders, and field studies
Article Abstract:
Petranka criticized Ash's 1997 study of salamander populations in southern Appalachia for pseudoreplication, but it is unavoidable due to practical and financial constraints. The analyses that used pseudoreplication were intended to demonstrate similarity between sites, and are not critical to the paper. More studies are needed to resolve the debate.
