Inbreeding depression—the reduced survival and fertility of offspring of related individuals—
occurs in wild animal and plant populations as well as in humans, indicating that genetic …

Flowering plants exhibit two principal life-history strategies: annuality (living and
reproducing in one year) and perenniality (living more than one year). The advantages of …

In recent years, scientists have realized that evolution can occur on timescales much shorter
than the" long lapse of ages" emphasized by Darwin—in fact, evolutionary change is …

Habitat loss and fragmentation are among the biggest threats to biodiversity. Anthropogenic
habitat fragmentation leads to small and isolated remnant plant and animal populations. The …

Most of the world's land surface is currently under human use and natural habitats remain as
fragmented samples of the original landscapes. Measuring the quality of plant progeny sired …

The role of genetic factors in extinction has been a controversial issue, especially since
Lande's paper [Genetics and demography in biological conservation, Science 241 (1988) …

H abitat fragmentation-the reduction of continuous habitat into several smaller spatially
isolated remnants-is a significant threat to the maintenance of biodiversity in many terrestrial …

Inbreeding depression (reduced fitness of individuals with related parents) has long been a
major focus of ecology, evolution, and conservation biology. Despite decades of research …

Many ecosystem services are delivered by organisms that depend on habitats that are
segregated spatially or temporally from the location where services are provided …

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 …
