Data from: Climate and local abundance in freshwater fishes

Jason H. Knouft & Melissa M. Anthony
Identifying factors regulating variation in numbers of individuals among populations across a species' distribution is a fundamental goal in ecology. A common prediction, often referred to as the abundant-centre hypothesis, suggests that abundance is highest near the centre of a species' range. However, because of the primary focus on the geographical position of a population, this framework provides little insight into the environmental factors regulating local abundance. While range-wide variation in population abundance associated with...

Data from: Single nucleotide polymorphism discovery via genotyping by sequencing to assess population genetic structure and recurrent polyploidization in Andropogon gerardii

Christine McAllister, Allison J. Miller & Christine A. McAllister
Premise of the study. Autopolyploidy, genome duplication within a single lineage, can result in multiple cytotypes within a species. Geographic distributions of cytotypes may reflect the evolutionary history of autopolyploid formation and subsequent population dynamics including stochastic (drift) and deterministic (differential selection among cytotypes) processes. Here, we used a population genomic approach to investigate whether autopolyploidy occurred once or multiple times in Andropogon gerardii, a widespread, North American grass with two predominant cytotypes. Methods. Genotyping-by-sequencing...

Data from: DNA barcodes of the native ray-finned fishes in Taiwan

Species identification based on the DNA sequence of a fragment of the cytochrome c oxidase subunit I (COI) gene in the mitochondrial genome, DNA barcoding, is widely applied to assist in sustainable exploitation of fish resources and the protection of fish biodiversity. The aim of this study was to establish a reliable barcoding reference database of the native ray-finned fishes in Taiwan. A total of 2,993 individuals, belonging to 1,245 species within 637 genera, 184...

Data from: Local population density and group composition influence signal-preference relationships in Enchenopa treehoppers (Hemiptera: Membracidae)

Kasey D. Fowler-Finn, Daniel C. Cruz & Rafael L. Rodriguez
Many animals exhibit social plasticity—changes in phenotype or behavior in response to experience with conspecifics—that change how evolutionary processes like sexual selection play out. Here, we asked whether social plasticity arising from variation in local population density in male advertisement signals and female mate preferences influences the form of sexual selection. We manipulated local density and determined whether this changed how the distribution of male signals overlapped with female preferences—i.e., the signal-mate preference relationship. We...

Data from: Bee communities along a prairie restoration chronosequence: similar abundance and diversity, distinct composition

Rebecca K. Tonietto, John S. Ascher & Daniel J. Larkin
Recognition of the importance of bee conservation has grown in response to declines of managed honey bees and some wild bee species. Habitat loss has been implicated as a leading cause of declines, suggesting that ecological restoration is likely to play an increasing role in bee conservation efforts. In the Midwestern USA, restoration of tallgrass prairie has traditionally targeted plant community objectives without explicit consideration for bees. However, restoration of prairie vegetation is likely to...
