Although the potential genetic risks associated with rare or endangered plants and small
populations have been discussed previously, the practical role of population genetics in …

Whether inbreeding affects the demography and persistence of natural populations has
been questioned. However, new pedigree data from field populations and molecular and …

Genetic diversity is one of the three forms of biodiversity recognized by the World
Conservation Union (IUCN) as deserving conservation. The need to conserve genetic …

Reintroduction of native species has become increasingly important in conservation
worldwide for recovery of rare species and restoration purposes. However, few studies have …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

Most ecologists are not card-carrying members of either individualistic or interdependent
guilds, but our perception of plant community organization, and the way we conduct …

In a fragmented, dry subtropical forest in northwestern Argentina, we compared pollination
levels, fruit set, and seed set among small (< 1 ha) forest fragments, large (> 2 ha) fragments …

The ecological significance of spacing among plants in contributing to the maintenance of
species richness, particularly in tropical forests, has received considerable attention that has …

Urbanization within the Tucson Basin of Arizona during the past 50+ years has fragmented
the original desert scrub into patches of different sizes and ages. These remnant patches …

Allee effects may be experienced by plants when populations are too small or isolated to
receive sufficient pollinator services to replace themselves. This article reports experimental …
