University of Connecticut Mark Urban
Eco-Evolution in Space

We study the ecological and evolutionary mechanisms that shape natural communities across multiple spatial scales

Evolution at Small Spatial Scales

Trends in Ecology & Evolution

We establish a quantitative definition of microgeographic adaptation that standardizes dispersal abilities, enabling this measure to be compared across species.

Plastic and Evolutionary Responses to Climate Change in Amphibians and Reptiles

Evolutionary Applications

Plastic and genetic variation in amphibians and reptiles could buffer some of the formidable threats from climate change, but large uncertainties remain owing to limited data.

Asymmetric Selection and the Evolution of Extraordinary Defences

Nature Communications

Extraordinary defences can evolve in response to asymmetrical selection when marginal risks of insufficient defence exceed marginal costs of excessive defence.

Evolution Mediates the Effects of Apex Predation on Aquatic Food Webs

Proceedings of the Royal Society

Local adaptation of prey to apex predators can alter local food webs by mediating top-down (predator-dependent) ecological effects.

October 2013

The Yale School of Forestry and Environmental Studies featured post-doc Jonathan Richardson's research in their most recent Research Report.

Our new Evolutionary Applications paper is part of a comprehensive synthesis reviewing what is currently known – and not known – about phenotypic responses to climate change in a variety of taxa. Specifically, we focus on the responses of amphibians and reptiles.
