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 …

Understanding the mechanisms of population size regulation is of vital importance to both
the pure and applied ecologist. Throughout the history of ecology one school of thought has …

The local density of a plant population can influence both the number of pollinators attracted
and the behavior (and thus pollination efficiency) of those that are. I present the results of a …

1 The termdensity-dependence'is often applied rather loosely to a variety of aspects of local
abundance.Density'is most commonly measured as the size of a local population and/or the …

The four chapters in which Professor Willson presents her study of the evolution and
interaction of plant reproductive mechanisms in relation to ecological factors are entitled (1) …

“It is not only the species that change evolutionarily through interactions... the interactions
themselves also change.” Thus states John N. Thompson in the foreword to Interaction and …

Ideally, experimental studies in ecology examine the response of genetically similar
organisms to different environments or of genetically different organisms to similar …

Although predispersal seed predation by insects is common, no test exists of its effect on
plant recruitment. This study examines seed predation in the population dynamics of a …

In this study we examined cross—pollination and levels of insect and vertebrate predation
on the seeds of beech as a function of stand size and tree size. Cross—pollination in this …

This study examines the factors that limit female reproductive function (fruit and seed
production) in the annual plant, Cassia fasciculata Michx.(Leguminosae), an hermaphroditic …
