The data underlying scientific papers should be accessible to researchers both now and in the future, but how best can we ensure that these data are available? Here we examine the effectiveness of four approaches to data archiving: no stated archiving policy, recommending (but not requiring) archiving, and two versions of mandating data deposition at acceptance. We control for differences between data types by trying to obtain data from papers that use a single, widespread...
Strong barriers to genetic exchange can exist at divergently selected loci, whereas alleles at neutral loci flow more readily between populations, thus impeding divergence and speciation in the face of gene flow. However, ‘divergence hitchhiking’ theory posits that divergent selection can generate large regions of differentiation around selected loci. ‘Genome hitchhiking’ theory suggests that selection can also cause reductions in average genome-wide rates of gene flow, resulting in widespread genomic divergence (rather than divergence only...
Data from: Butterfly community ecology: the influences of habitat type, weather patterns, and dominant species in a temperate ecosystemNatalie Robinson, Stephen Armstead & M. Deane Bowers
We compared variation in butterfly communities across 3 years at six different habitats in a temperate ecosystem near Boulder, Colorado, USA. These habitats were classified by the local Open Space consortium as: Grasslands, Tallgrass, Foothills Grasslands, Foothills Riparian, Plains Riparian, and Montane Woodland. Rainfall and temperature varied considerably during these years. We surveyed butterflies using the Pollard-Yates method of invertebrate sampling, and compared abundance, species richness, and diversity across habitats and years. Communities were most...
Data from: Historical stocking data and 19th century DNA reveal human-induced changes to native diversity and distribution of cutthroat troutJessica L. Metcalf, Sierra L. Love Stowell, Christopher M. Kennedy, Kevin B. Rogers, Daniel McDonald, Kyle Keepers, Janet Epp, Alan Cooper, Jeremy J. Austin & Andrew P. Martin
Many species are threatened with extinction and efforts are underway worldwide to restore imperiled species to their native ranges. Restoration requires knowledge of species’ historic diversity and distribution, which may not be available. For some species, many populations were extirpated and humans moved individuals beyond their native range before native diversity and distribution were documented. Moreover, traditional taxonomic assessments often failed to accurately capture phylogenetic diversity. We illustrate a general approach for estimating regional native...
The belly button is one of the habitats closest to us, and yet it remains relatively unexplored. We analyzed bacteria and arachaea from the belly buttons of humans from two different populations sampled within a nation-wide citizen science project. We examined bacterial and archaeal phylotypes present and their diversity using multiplex pyrosequencing of 16S rDNA libraries. We then tested the oligarchy hypothesis borrowed from tropical macroecology, namely that the frequency of phylotypes in one sample...
The first analyses of gene sequence data indicated that the eukaryotic tree of life consisted of a long stem of microbial groups ‘topped’ by a crown containing plants, animals, and fungi and their microbial relatives. While more recent multigene concatenated analyses have refined the relationships among the many branches of eukaryotes, the root of the eukaryotic tree of life has remained elusive. Inferring the root of extant eukaryotes is challenging because of the age of...
Data from: Noise pollution alters ecological services: enhanced pollination and disrupted seed dispersalClinton D. Francis, Nathan J. Kleist, Catherine P. Ortega & Alexander Cruz
Noise pollution is a novel, widespread environmental force that has recently been shown to alter the behavior and distribution of birds and other vertebrates, yet whether noise has cumulative, community-level consequences by changing critical ecological services is unknown. Herein, we examined the effects of noise pollution on pollination and seed dispersal and seedling establishment within a study system that isolated the effects of noise from confounding stimuli common to human-altered landscapes. Using observations, vegetation surveys...
