Data from: Late Pleistocene range expansion of North American topminnows accompanied by admixture and introgression.

David D. Duvernell, Eric Westhafer & Jacob F. Schaefer
Aim: We used genome-scale sampling to assess the phylogeography of a group of topminnows in the Fundulus notatus species complex. Two of the species have undergone extensive range expansions resulting in broadly overlapping distributions, and sympatry within drainages has provided opportunities for hybridization and introgression. We assess the timing and pattern of range expansion in the context of late-Pleistocene-Holocene drainage events, and evaluate the evidence for introgressive hybridization between species. Location: Central and southern United...

Toonen, Contributing Members Of Diversity Of The Indo-Pacific Network & Michelle R. Gaither
Aim: To test hypothesized biogeographic partitions of the tropical Indo-Pacific Ocean with phylogeographic data from 56 taxa, and to evaluate the strength and nature of barriers emerging from this test. Location: The Indo-Pacific Ocean. Time Period: Pliocene through the Holocene. Major Taxa Studied: 56 marine species. Methods: We tested eight biogeographic hypotheses for partitioning of the Indo-Pacific using a novel modification to analysis of molecular variance. Putative barriers to gene flow emerging from this analysis...

Data from: Chromosome polymorphisms track trans‐Atlantic divergence and secondary contact in Atlantic salmon

Pleistocene glaciations drove repeated range contractions and expansions shaping contemporary intraspecific diversity. Atlantic salmon (Salmo salar) in the western and eastern Atlantic diverged >600,000 YBP, with the two lineages isolated in different southern refugia during glacial maxima, driving trans-Atlantic genomic and karyotypic divergence. Here, we investigate genomic consequences of glacial isolation and trans-Atlantic secondary contact using 108,870 single nucleotide polymorphisms (SNPs) genotyped in 80 North American and European populations. Throughout North America, we identified extensive...

Data from: The role of temperature in affecting carry-over effects and larval competition in the globally invasive mosquito, Aedes albopictus

Nnaemeka F. Ezeakacha & Donald. A. Yee
Background: Ectotherms, like mosquitoes, have evolved specific responses to variation in environmental conditions like temperature, and these responses could confer a fitness benefit or cost when carried-over to different life stages. However, effects of temperature on animals with complex life-cycles often only focus on part of their life-cycle, or only consider how single aspects of life-history may carry over to new stages. Herein we investigated how temperature affects intraspecific larval competition and carry-over effects from...

Data from: Resource constraints highlight complex microbial interactions during lake biofilm development

Abstract 1. This study evaluated how the availability of nutrients and organic carbon interact to influence the associations between autotrophic and heterotrophic microorganisms during lake biofilm development. Considering that decomposers are often better competitors for nutrients than producers in aquatic environments, we hypothesized that heterotrophs would outcompete autotrophs for available nutrients unless heterotrophs were limited by organic carbon provided by autotrophs. 2. To test our hypothesis, we evaluated autotrophic (algae) and heterotrophic (fungi, bacteria) biomass...
