Abstract: The nested subset hypothesis states that the species comprising a depauperate insular biota are a proper subset of those in richer biotas, and that an archipelago of such biotas, ranked by species richness, presents a nested series. The pattern characterizes the distributions of mammals in three different archipelagos, and it appears more strongly developed among faunas in the process of, Cited by: Nested Subsets and Biological Conservation Patterson Introduction Studies of island biotas have been important to the de-velopment of ecological and evolutionary theory since the time of Darwin and Wallace, and the relevance of such work to isolated biological preserves is clear (cf.

Smaller insular biotas do not represent a random draw of the species in the source pool but instead represent highly nonrandom, nested subsets of those species.

The species found in various kinds of ecological communities often comprise nested subsets of those inhabiting richer ones. This phenonenon, termed nested subsets or nestedness, has biogeographic, ecological, and coevolutionary consequences.

It also has important implications for biological conservation. The principle of nested subsets and its implications for biological conservation. Conserv. Nested biotas and biological conservation: metrics, mechanisms, and meaning of Cited by: 2.

Like the species-area relationship, nested structures are observed in many types of habitat and in many taxa, and also like the species-area relationship, it has been suggested to have implications for biological conservation, particularly in connection with the ‘single large or several small’ (SLOSS) debate regarding nature reserve by:   The principle of nested subsets and its implications for biological conservation.

Various aspects of the relation between area of protected habitat and numbers of constituent species preserved are discussed, with emphasis of edge effects and other by: The single large or several small (SLOSS) problem has been addressed in a large number of empirical and theoretical studies, but no coherent conclusion has yet been reached.

McDonald and Brown developed a model based on island biogeographic principles to predict the magnitude and composition of small mammal extinctions from isolated boreal habitats atop mountains of the Great Basin following global warming.

Introduction. The concept of nested subsets (Patterson and Atmar, ) proposes that species which form an impoverished insular biota are a non-random subset of the ones found in species-rich a perfectly nested structure, all species from poorer communities are present in richer communities, whereas the reverse is not true (Patterson, ; Patterson and Atmar, ).
