The phenomenology of niche evolution via quantitative traits in a ‘black-hole’ sink
Previous studies of adaptive evolution in sink habitats (in which isolated populations of a species cannot persist deterministically) have highlighted the importance of demographic constraints inExpand

Evolution in Stage-Structured Populations
For many organisms, stage is a better predictor of demographic rates than age. Yet no general theoretical framework exists for understanding or predicting evolution in stage-structured populations.Expand

The effects of density dependence and immigration on local adaptation and niche evolution in a black-hole sink environment.
We examine the effects of density dependence and immigration on local adaptation in a "black-hole sink" habitat, i.e., a habitat in which isolated populations of a species would tend to extinctionExpand

Temporal Autocorrelation Can Enhance the Persistence and Abundance of Metapopulations Comprised of Coupled Sinks
In spatially heterogeneous landscapes, some habitats may be persistent sources, providing immigrants to sustain populations in unfavorable sink habitats (where extinction is inevitable withoutExpand

Theoretical Perspectives on the Statics and Dynamics of Species’ Borders in Patchy Environments
Understanding range limits is a fundamental problem in ecology and evolutionary biology. In 1963, Mayr argued that “contaminating” gene flow from central populations constrained adaptation inExpand

Physical, chemical, and biotic effects on arctic zooplankton communities and diversity
We examined how physical and chemical factors and fish populations affected the presence and density of zooplankton species in 104 Alaskan arctic lakes. Five fish species and nine zooplankters wereExpand

Predator shadows: complex life histories as generators of spatially patterned indirect interactions across ecosystems
Ecological coupling by material exchanges or dispersal between spatially distinct communities has important impacts on ecological processes, such as diversity–stability relationships, ecosystemExpand

Genetics, adaptation, and invasion in harsh environments
We analyze mathematical models to examine how the genetic basis of fitness affects the persistence of a population suddenly encountering a harsh environment where it would go extinct withoutExpand

Temporal Variation Can Facilitate Niche Evolution in Harsh Sink Environments
We examine the impact of temporal variation on adaptive evolution in “sink” environments, where a species encounters conditions outside its niche. Sink populations persist because of recurrentExpand
