Welfare threatened species

Clinical pathologists--a threatened species?

All pathologists, and especially those of you who are of my generation, have been giving increasing thought to the career prospects for young doctors and share, with me, concern with the declining recruitment to our speciality. Like you, I can look back over some twenty or thirty years to the days of numerous applicants for Consultant Pathologist posts, impressive short-lists with candidates of...

Categorization systems of threatened species.

de Grammont and Cuarón (2006) provide interesting information about the way several countries of the Western Hemisphere address the issue of developing systems for threatened species categorization. Nevertheless, we disagree with these authors on some fundamental points and think their conclusions that “the country categorizations [they] evaluated have serious defects” and that “the IUCN (2001)...

Facilitating Recovery of Threatened and Endangered Species

Optimal Translocation Strategies for Threatened Species

Translocation—the deliberate, human-mediated movement of organisms—is a useful conservation tool most often employed in attempts to increase persistence of threatened or depleted species. Translocation projects involve difficult management decisions regarding the allocation of animals between sites. This research provides a rational scientific basis for these decisions. We use a stochastic popu...

Loss of pathogens in threatened plant species

Global declines in biodiversity create an urgent need to address the impact of infectious disease in the small and fragmented populations that characterize threatened species. However, the paucity of empirical data provides little ability to predict whether disease generally accelerates threatened species towards extinction or becomes less important as populations decline. Th is study tests whe...
