Data from: Private land conservation has landscape-scale benefits for wildlife in agroecosystems

John M. Yeiser, John J. Morgan, Danna L. Baxley, Richard B. Chandler & James A. Martin
Private lands contain much of the world's biodiversity. Conservation of private land, especially agricultural land, is urgent yet challenging because of the diverse priorities of landowners. Local effects of farmland conservation programmes have been evaluated thoroughly, but population-level response to these programmes may depend on effects that extend beyond targeted land parcels. We investigated the landscape-scale effects of a grassland conservation initiative, the Conservation Reserve Enhancement Program (CREP), on a socially and economically important gamebird,...

Data from: Impacts of biomass production at civil airports on grassland bird conservation and aviation strike risk

Tara J. Conkling, Jerrold L. Belant, Travis L. DeVault & James A. Martin
Growing concerns about climate change, foreign oil dependency, and environmental quality have fostered interest in perennial native grasses (e.g. switchgrass [Panicum virgatum]) for bioenergy production while also maintaining biodiversity and ecosystem function. However, biomass cultivation in marginal landscapes such as airport grasslands may have detrimental effects on aviation safety as well as conservation efforts for grassland birds. In 2011–2013 we investigated effects of vegetation composition and harvest frequency on seasonal species richness and habitat use...

Data from: Linking the vectorial capacity of multiple vectors to observed patterns of West Nile virus transmission

Joseph R. McMillan, Rebekah A. Blakney, Daniel G. Mead, William T. Koval, Sarah M. Coker, Lance A. Waller, Uriel Kitron & Gonzalo M. Vazquez-Prokopec
1. Theoretical models suggest that increased vector species participation in pathogen transmission significantly increases the prevalence of vector and host infections. However, there has been a lack of empirical evidence to support this. 2. We linked transmission potential of multiple vectors species to observed patterns of enzootic pathogen transmission by conducting longitudinal field surveillance of West Nile virus (WNv) infections in Culex spp. mosquitoes and avian host communities in the southeastern U.S. We then used...

Data from: Predictable gene expression related to behavioral variation in parenting

Kyle M. Benowitz, Elizabeth C. McKinney, Christopher B. Cunningham & Allen J. Moore
Differential gene expression has been associated with transitions between behavioral states for a wide variety of organisms and behaviors. Heterochrony, genetic toolkits, and predictable pathways underlying behavioral transitions have been hypothesized to explain the relationship between transcription and behavioral changes. Less studied is how variation in transcription is related to variation within a behavior, and if the genes that are associated with this variation are predictable. Here we adopt an evolutionary systems biology perspective to...

Data from: Male body size predicts reproductive success but not within-clutch paternity patterns in gopher tortoises (Gopherus polyphemus)

K. Nicole White, Betsie B. Rothermel, Kelly R. Zamudio & Tracey D. Tuberville
In many vertebrates, body size is an important driver of variation in male reproductive success. Larger, more fit individuals are more likely to dominate mating opportunities, skewing siring success and resulting in lower effective population sizes and genetic diversity. The mating system of the gopher tortoise (Gopherus polyphemus) has been characterized as both female-defense and scramble-competition polygyny. Mating systems are typically not fixed and can be influenced by factors such as population density, demographic structure,...

Data from: Animal-mediated organic matter transformation: aquatic insects as a source of microbially bioavailable organic nutrients and energy

Thomas B. Parr, Krista A. Capps, Shreeram P. Inamdar & Kari A. Metcalf
1. Animal communities are essential drivers of energy and elemental flow in ecosystems. However, few studies have investigated the functional role of animals as sources of dissolved organic matter (DOM) and the subsequent utilization of that DOM by the microbial community. 2. In a small forested headwater stream, we tested the effects of taxonomy, feeding traits, and body size on the quality and quantity of dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) excreted...

Data from: Genetic dissection of hybrid male sterility across stages of spermatogenesis

Denise J. Schwahn, Richard J. Wang, Michael A. White & Bret A. Payseur
Hybrid sterility is a common form of reproductive isolation between nascent species. Although hybrid sterility is routinely documented and genetically dissected in speciation studies, its developmental basis is rarely examined, especially in generations beyond the F1. To identify phenotypic and genetic determinants of hybrid male sterility from a developmental perspective, we characterized testis histology in 312 F2 hybrids generated by intercrossing inbred strains of Mus musculus domesticus and M. m. musculus, two subspecies of house...

Data from: Formation of a recent hybrid zone offers insight to the geographic puzzle and maintenance of species boundaries in musk turtles

Peter A. Scott, Travis C. Glenn & Leslie J. Rissler
Speciation is the result of an accumulation of reproductive barriers between populations, pinpointing these factors is often difficult. However, hybrid zones can form when these barriers are not complete, especially when lineages come into contact in intermediate or modified habitats. We examine a hybrid zone between two closely related riverine turtle species, Sternotherus depressus and S. peltifer, and use ddRAD sequencing to to understand how this hybrid zone formed and elucidate genomic patterns of reproductive...

O-specific polysaccharide confers lysozyme resistance to extraintestinal pathogenic Escherichia coli

Yinli Bao, Haobo Zhang, Xinxin Huang, Jiale Ma, Catherine M. Logue, Lisa K. Nolan & Ganwu Li
Extraintestinal pathogenic Escherichia coli (ExPEC) is the leading cause of bloodstream and other extraintestinal infections in human and animals. The greatest challenge encountered by ExPEC during an infection is posed by the host defense mechanisms, including lysozyme. ExPEC have developed diverse strategies to overcome this challenge. The aim of this study was to characterize the molecular mechanism of ExPEC resistance to lysozyme. For this, 15,000 transposon mutants of a lysozyme-resistant ExPEC strain NMEC38 were screened;...
