Data from: Parallel molecular routes to cold adaptation in eight genera of New Zealand stick insects

Alice B. Dennis, Luke T. Dunning, Brent J. Sinclair & Thomas R. Buckley
The acquisition of physiological strategies to tolerate novel thermal conditions allows organisms to exploit new environments. As a result, thermal tolerance is a key determinant of the global distribution of biodiversity, yet the constraints on its evolution are not well understood. Here we investigate parallel evolution of cold tolerance in New Zealand stick insects, an endemic radiation containing three montane-occurring species. Using a phylogeny constructed from 274 orthologous genes, we show that stick insects have...

Data from: A call for more transparent reporting of error rates: the quality of AFLP data in ecological and evolutionary research

Lindsay A. Crawford, Daria Koscinski & Nusha Keyghobadi
Despite much discussion of the importance of quantifying and reporting genotyping error in molecular studies, it is still not standard practice in the literature. This is particularly a concern for amplified fragment length polymorphism (AFLP) studies, where differences in laboratory, peak-calling and locus-selection protocols can generate data sets varying widely in genotyping error rate, the number of loci used and potentially estimates of genetic diversity or differentiation. In our experience, papers rarely provide adequate information...

Data from: Model and test in a fungus of the probability that beneficial mutations survive drift

Danna R. Gifford, J. Arjan G. M. De Visser & Lindi M. Wahl
Determining the probability of fixation of beneficial mutations is critically important for building predictive models of adaptive evolution. Despite considerable theoretical work, models of fixation probability have stood untested for nearly a century. However, recent advances in experimental and theoretical techniques permit the development of models with testable predictions. We developed a new model for the probability of surviving genetic drift, a major component of fixation probability, for novel beneficial mutations in the fungus Aspergillus...

Data from: Eating local: influences of habitat on the diet of little brown bats (Myotis lucifugus)

Elizabeth L Clare, Brittany R Barber, Bernard W Sweeney, Paul DN Hebert & M Brock Fenton
We employ molecular methods to profile the diet of the little brown bat, Myotis lucifugus, and describe spatial and temporal changes in diet over their maternity season. We identified 61 prey species of insects and 5 species of arachnid. The largest proportion of prey (∼32%) were identified as species of the mass-emerging Ephemeroptera (mayfly) genus Caenis. Bats roosting in agricultural settings had lower dietary richness than those occupying a roost located on a forest fragment...

Data from: Basal cold but not heat tolerance constrains plasticity among Drosophila species (Diptera: Drosophilidae)

Casper Nyamukondiwa, John S Terblanche, Katie E Marshall & Brent J Sinclair
Thermal tolerance and its plasticity are important for understanding ectotherm responses to climate change. However, it is unclear whether plasticity is traded off at the expense of basal thermal tolerance and if plasticity is subject to phylogenetic constraints. Here, we investigated associations between basal thermal tolerance and acute plasticity thereof in laboratory-reared adult males of eighteen Drosophila species at low and high temperatures. We determined the high and low temperatures where 90 % of flies...
