The paradox of forest fragmentation genetics.
Theory predicts widespread loss of genetic diversity from drift and inbreeding in trees subjected to habitat fragmentation, yet empirical support of this theory is scarce. We argue that populationExpand

Managing Species Diversity in Tallgrass Prairie: Assumptions and Implications
Conservation and restoration ecology efforts may conserve or restore a particular image of a community, a variety of plausible images, or maximum biological diversity. The choice is a policy decisionExpand

Early Consequences of Seed Dispersal for a Neotropical Tree (Virola surinamensis)
We examined the effects of distance from a fruiting conspecific, light environment, and initial seed size on survivorship using Virola surinamensis seeds and seedlings placed in concentric ringsExpand

Response of Early‐ and Late‐Flowering Plants to Fire Season in Experimental Prairies
Fire maintains tallgrass prairies, but fire season is virtually unexplored as a formative influence of prairie floristics. Replicated mid—July burns, simulating the peak of lightning—caused fire inExpand

When Seed Dispersal Matters
Abstract A profusion of fruit forms implies that seed dispersal plays a central role in plant ecology, yet the chance that an individual seed will ultimately produce a reproductive adult is low toExpand

Characterization of highly variable (GA/CT)n microsatellites in the bur oak, Quercus macrocarpa
The objective of this study was to ascertain the usefulness of polymerase chain reaction (PCR)-based microsatellite analysis for studying pollination and parentage in a wind-pollinated temperateExpand

Episodic death across species of desert shrubs.
Extreme events shape population and community trajectories. We report episodic mortality across common species of thousands of long-lived perennials individually tagged and monitored for 20 years inExpand

Arrival and Survival in Tropical Treefall Gaps
Most tropical tree species require light from a treefall gap at some time during their lives to reach maturity. Responses to light conditions have been dichotomized as shade-intolerant pioneers orExpand

EGG SIZE, HATCHING ASYNCHRONY, SEX, AND BROOD REDUCTION IN THE COMMON GRACKLE'
In clutches of five, the Common Grackle (Quiscalus quiscula) provisions eggs un- equally and starts incubation before the clutch is complete, thereby insuring initial advantages to some young whichExpand

SummaryFruit-eating animals deposit viable seeds in patterns that determine the conditions under which seeds and seedlings live or die. Many tree species are scatter-dispersed by birds, bats, orExpand
