Phylogenies and Community Ecology
▪ Abstract As better phylogenetic hypotheses become available for many groups of organisms, studies in community ecology can be informed by knowledge of the evolutionary relationships amongExpand

Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
A latitudinal gradient in biodiversity has existed since before the time of the dinosaurs, yet how and why this gradient arose remains unresolved. Here we review two major hypotheses for the originExpand

The Evolution of Dispersal in Spatially and Temporally Varying Environments
Using a simple two-patch model, we examine how patterns of spatial and temporal variation in carrying capacities affect natural selection on dispersal. The size of the population in each patch isExpand

EARLY BURSTS OF BODY SIZE AND SHAPE EVOLUTION ARE RARE IN COMPARATIVE DATA
George Gaylord Simpson famously postulated that much of life's diversity originated as adaptive radiations—more or less simultaneous divergences of numerous lines from a single ancestral adaptiveExpand

Clades diversify in an ecological context, but most macroevolutionary models do not directly encapsulate ecological mechanisms that influence speciation and extinction. A data set of 245 chordate,Expand

DETERMINATION OF SPECIES COMPOSITION IN THE ENALLAGMA DAMSELFLY ASSEMBLAGES OF PERMANENT LAKES
In this study I investigated the important ecological interactions that contribute to maintaining a striking species distributional pattern for the Enallagma damselflies (Odonata: Coenagrionidae)Expand

Behavioral Differences between Enallagma Species (Odonata) Influencing Differential Vulnerability to Predators
In previous research I have shown that fish predation contributes to the exclusion of a group of Enallagma species (Odonata: Zygoptera) from lakes containing fish, whereas dragonfly predationExpand

Enhanced Fitness Conferred by Naturally Occurring Variation in the Circadian Clock
Natural variation in clock parameters is necessary for the circadian clock to contribute to organismal fitness over a broad geographic range. Considerable variation is evident in the period, phase,Expand

Estimating metazoan divergence times with a molecular clock.
Accurately dating when the first bilaterally symmetrical animals arose is crucial to our understanding of early animal evolution. The earliest unequivocally bilaterian fossils are approximately 555Expand
