Data from: Cast adrift on an island: introduced populations experience an altered balance between selection and drift

Eric M. O'Neill, Karen H. Beard, Michael E. Pfrender, M. E. Pfrender, E. M. O'Neill & K. H. Beard
A long-standing question in evolutionary biology is what becomes of adaptive traits when a species expands its range into novel environments. Here we report the results of a study on an adaptive colour pattern polymorphism (stripes) of the coqui frog following its introduction to Hawaii from Puerto Rico. We compared population differentiation (φ'ST and FST) for the stripes locus —which underlies this colour pattern polymorphism— with neutral microsatellite loci to test for a signature of...

Data from: Potential for local adaptation in response to an anthropogenic agent of selection: effects of road deicing salts on amphibian embryonic survival and development

Gareth R. Hopkins, Susannah S. French, Brodie Jr., Edmund D. & Edmund D. Brodie
The application of millions of tons of road deicing salts every winter in North America presents significant survival challenges to amphibians inhabiting road-side habitats. While much is known of the effects of NaCl on anuran tadpoles, less is known of effects on amphibian eggs, or any caudate life-stage. In addition, little is known of the effects of MgCl2, which is now the 2nd most commonly used road deicer. Most studies have considered amphibians to be...

Data from: Niche opportunities and invasion dynamics in a desert annual community

Ginger R. H. Allington, Thomas J. Valone, David N. Koons, S. K. Morgan Ernest, Michele R. Schutzenhofer & S. K. Morgan Ernest
Although many factors influence the ability of exotics to invade successfully, most studies focus on only a few variables to explain invasion; attempts at theoretical synthesis are largely untested. The niche opportunities framework proposes that the demographic success of an invader is largely affected by the availability of resources and the abundance of its enemies. Here, we use a 31-year study from a desert ecosystem to examine the niche opportunities framework via the invasion of...
