Data from: Patterns of authorship in ecology and evolution: first, last and corresponding authorship vary with gender and geography

Charles W. Fox, Josiah P. Ritchey, C.E. Timothy Paine & C. E. Timothy Paine
The position of an author on the byline of a paper affects the inferences readers make about their contributions to the research. We examine gender differences in authorship in the ecology literature using two datasets: submissions to six journals between 2010 and 2015 (regardless of whether they were accepted), and manuscripts published by 151 journals between 2009 and 2015. Women were less likely to be last (i.e., ‘senior’) authors (averaging ~23% across journals, years and...

Data from: The effectiveness of journals as arbiters of scientific quality

C.E. Timothy Paine, Charles W. Fox & C. E. Timothy Paine
Academic publishers purport to be arbiters of knowledge, aiming to publish studied that advance the frontiers of their research domain. Yet the effectiveness of journal editors at identifying novel and important research is generally unknown, in part because of the confidential nature of the editorial and peer-review process. Using questionnaires, we evaluated the degree to which journals are effective arbiters of scientific impact in the domain of Ecology, quantified by three key criteria. First, journals...

Data from: Lake regionalization and diatom metacommunity structuring in tropical South America

Xavier Benito, Sherilyn C. Fritz, Miriam Steinitz-Kannan, Maria I. Vélez & Michael M. McGlue
Lakes and their topological distribution across Earth’s surface impose ecological and evolutionary constraints on aquatic metacommunities. In this study, we group similar lake ecosystems as metacommunity units influencing diatom community structure. We assembled a database of 195 lakes from the tropical Andes and adjacent lowlands (8ºN–30ºS and 58–79ºW) with associated environmental predictors to examine diatom metacommunity patterns at two different levels: taxon and functional (deconstructed species matrix by ecological guilds). We also derived spatial variables...

Data from: Geographic clines in wing morphology relate to colonization history in New World but not Old World populations of yellow dung flies

Martin A. Schaefer, David Berger, Patrick T. Rohner, Anders Kjaersgaard, Stephanie S. Bauerfeind, Frédéric Guillaume, Charles W. Fox, Wolf Blanckenhorn & Wolf U. Blanckenhorn
Geographic clines offer insights about putative targets and agents of natural selection as well as tempo and mode of adaptation. However, demographic processes can lead to clines that are indistinguishable from adaptive divergence. Using the widespread yellow dung fly Scathophaga stercoraria (Diptera: Scathophagidae), we examine quantitative genetic differentiation (QST) of wing shape across North America, Europe and Japan, and compare this differentiation with that of ten microsatellites (FST). Morphometric analyses of 28 populations reared at...

Cleland, Scott Collins, Philip A. Fay, Jennifer Firn, Nicole Hagenah, Yann Hautier, Oscar Iribarne, Johannes M.H. Knops, Rebecca L. McCulley, Andrew MacDougall, Joslin L. Moore, John W. Morgan, Brent Mortensen, Kimberly J. La Pierre … & Johannes M. H. Knops
Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental change typically quantify biotic responses at single spatial (time series within a single plot) or temporal (spatial beta-diversity at single time points) scales, ignoring their potential interdependence. Here, we use data from a global network of grassland experiments to determine how turnover responses to two major...

Data from: A genomic assessment of population structure and gene flow in an aquatic salamander identifies the roles of spatial scale, barriers, and river architecture

Mason O. Murphy, Kara S. Jones, Steven J. Price & David W. Weisrock
Population structure and gene flow of species in lotic environments can be constrained by river network architecture, species life history and heterogeneous local barriers. Identifying the factors that influence population structure and gene flow, especially in species limited to movement within a river network, is vital for understanding the evolutionary and demographic history of a species. We explored population structure and gene flow for a fully aquatic salamander, the common mudpuppy (Necturus maculosus), in Kentucky...

Data from: Phylogenetic patterns of trait and trait plasticity evolution: Insights from amphibian embryos

Rick Relyea, Patrick R. Stephens, Lisa N. Barrow, Andrew Blaustein, Paul Bradley, Julia Buck, Ann Chang, Brian I Crother, James Collins, Julia Earl, Stephanie Gervasi, Jason T. Hoverman, Olliver Hyman, Emily Claire Moriarty Lemmon, Thomas Luhring, Moses Michelsohn, Christopher M. Murray, Steven Price, Raymond Semlitsch, Andy Sih, Aaron Stoler, Nick VandenBroek, Alexa Warwick, Greta Wengert, John Hammond … & Stephanie S. Gervasi
Environmental variation favors the evolution of phenotypic plasticity. For many species, we understand the costs and benefits of different phenotypes, but we lack a broad understanding of how plastic traits evolve across large clades. Using identical experiments conducted across North America, we examined prey responses to predator cues. We quantified five life history traits and the magnitude of their plasticity for 23 amphibian species/populations (spanning three families and five genera) when exposed to no cues,...

Data from: Mountaintop removal mining alters stream salamander population dynamics

Steven J. Price, Sara Beth Freytag, Simon J. Bonner, Andrea N. Drayer, Brenee' L. Muncy, Jacob M. Hutton & Christopher D. Barton
Aim: Population dynamics are often tightly linked to the condition of the landscape. Focusing on a landscape impacted by mountaintop removal coal mining (MTR), we ask the following questions: (1) How does MTR influence vital rates including occupancy, colonization and persistence probabilities, and conditional abundance of stream salamander species and life stages? (2) Do species and life stages respond similar to MTR mining or is there significant variation among species and life stages? Location: Freshwater...

Data from: Herbivory and eutrophication mediate grassland plant nutrient responses across a global climatic gradient

T. Michael Anderson, Daniel M. Griffith, James B. Grace, Eric M. Lind, Peter B. Adler, Lori A. Biederman, Dana M. Blumenthal, Pedro Daleo, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Andrew S. MacDougall, Rebecca L. McCulley, Suzanne M. Prober, Anita C. Risch, Mahesh Sankaran, Martin Schütz, Eric W. Seabloom, Carly J. Stevens, Lauren L. Sullivan, Peter D. Wragg & Elizabeth T. Borer
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: Substantial red wolf genetic ancestry persists in wild canids of southwestern Louisiana

Sean M. Murphy, Jennifer R. Adams, John J. Cox & Lisette P. Waits
Concerns over red wolf (Canis rufus) extinction caused by hybridization with coyotes (C. latrans) led to the capture and removal of remnant wild wolves from southwestern Louisiana and southeastern Texas, USA, during the 1970s. Here we show that despite decades of unmitigated hybridization, and declaration of endangered red wolves as functionally extinct in the wild, red wolf mitochondrial or nuclear DNA ancestry persists in ~55% of contemporary wild canids sampled in southwestern Louisiana. Surprisingly, one...

Data from: Replicated latitudinal clines in reproductive traits of European and North American yellow dung flies

Stephanie S. Bauerfeind, Martin A. Schäfer, David Berger, Wolf U. Blanckenhorn & Charles W. Fox
Geographic variation in phenotypic traits is commonly correlated with spatial variation in the environment, e.g., seasonality and mean temperature, providing evidence that natural selection generates such patterns. In particular, both body size and egg size of ectothermic animals are commonly larger in northern climates, and temperature induces plastic responses in both traits. Size-independent egg quality can also vary with latitude, though this is rarely investigated. For the widespread yellow dung fly (Scathophaga stercoraria; Diptera: Scathophagidae),...

Data from: Genomic data reject the hypothesis of sympatric ecological speciation in a clade of Desmognathus salamanders

Kara S. Jones & David W. Weisrock
Closely related taxa with dissimilar morphologies are often considered to have diverged via natural selection favoring different phenotypes. However, some studies have found these scenarios to be paired with limited or no genetic differentiation. Desmognathus quadramaculatus and D. marmoratus are sympatric salamander species thought to represent a case of ecological speciation based on distinct morphologies, but the results of previous studies have not resolved corresponding patterns of lineage divergence. Here, we use genome-wide data to...

Sex, hormone status, and growth rate influence dietary isotope fractionation in laboratory rats

Sora Kim & Jessica Santollo
Stable isotope analysis of rat tissues to determine effects of gonadectomization. Four groups - female, ovarectomized, male, and castrated male - were fed a constant diet for 30 days. Fat, muscle, liver, and kidney were sampled at the experiment's end while serum and blood were sampled at days 0, 1, and 30. We found that sex and removal of gonadal hormones are factors either individually or interactive for carbon and nitrogen stable isotope composition in...
