TL;DR: The social organization of a group of wolves in a large outdoor enclosure was followed through several breeding seasons and changes in social order and an increase in actual mating combinations suggest that some form of group selection could be operative in the wild.

TL;DR: Zoos have begun to make significant contributions as genetic refuges and reservoirs, especially for large vertebrate species threatened with extinction, and in developing this capacity zoos have fostered investigations into several facets of small population biology.

TL;DR: Fifty characters of extant advanced snakes were selected for phyletic analysis, with the primary aim of determining evolutionary paths of the venomous taxa, and the characters chosen showed roughly equivalent variation.

TL;DR: The effectiveness of the SSC is greatly enhanced by the close connections within its network between zoo professionals, academic scientists, field conservationists, and managers of natural resources.
