Data from: The oceanic concordance of phylogeography and biogeography: a case study in Notochthamalus

Christine Ewers-Saucedo, James M. Pringle, Hector H. Sepúlveda, James E. Byers, Sergio A. Navarrete & John P. Wares
Dispersal and adaptation are the two primary mechanisms that set the range distributions for a population or species. As such, understanding how these mechanisms interact in marine organisms in particular – with capacity for long-range dispersal and a poor understanding of what selective environments species are responding to – can provide useful insights for the exploration of biogeographic patterns. Previously, the barnacle Notochthamalus scabrosus has revealed two evolutionarily distinct lineages with a joint distribution that...

Data from: Efficacy of a probiotic bacterium to treat bats affected by the disease white-nose syndrome

Tina L. Cheng, Heather Mayberry, Liam P. McGuire, Joseph R. Hoyt, Kate E. Langwig, Hung Nguyen, Katy L. Parise, Jeffrey T. Foster, Craig K. R. Willis, Auston Marm Kilpatrick & Winifred F. Frick
The management of infectious diseases is an important conservation concern for a growing number of wildlife species. However, effective disease control in wildlife is challenging because feasible management options are often lacking. White-nose syndrome (WNS) is an infectious disease of hibernating bats that currently threatens several North American species with extinction. Currently, no effective treatments exist for WNS. We conducted a laboratory experiment to test the efficacy of treatment with Pseudomonas fluorescens, a bacterium that...

Data from: Adaptation to heat stress reduces phenotypic and transcriptional plasticity in a marine copepod

Morgan W. Kelly, M. Sabrina Pankey, Melissa B. DeBiasse & David C. Plachetzki
Organisms may respond to changing environments through phenotypic plasticity or adaptive evolution. These two processes are not mutually exclusive and may either dampen or strengthen each other's effects, depending on the genetic correlation between trait values and the slopes of their norms of reaction. To examine the effect of adaptation to heat stress on the plasticity of heat tolerance, we hybridized populations of the crustacean Tigriopus californicus that show divergent phenotypes for heat tolerance. We...

Data from: De novo genome assembly of Geosmithia morbida, the causal agent of thousand cankers disease

Taruna A. Schuelke, Anthony Westbrook, Kirk Broders, Keith Woeste & Matthew D. MacManes
Geosmithia morbida is a filamentous ascomycete that causes thousand cankers disease in the eastern black walnut tree. This pathogen is commonly found in the western U.S.; however, recently the disease was also detected in several eastern states where the black walnut lumber industry is concentrated. G. morbida is one of two known phytopathogens within the genus Geosmithia, and it is vectored into the host tree via the walnut twig beetle. We present the first de...

Data from: Brain transcriptional profiles of male alternative reproductive tactics and females in bluegill sunfish

Charlyn G. Partridge, Matthew D. MacManes, Rosemary Knapp & Bryan D. Neff
Bluegill sunfish (Lepomis macrochirus) are one of the classic systems for studying male alternative reproductive tactics (ARTs) in teleost fishes. In this species, there are two distinct life histories: parental and cuckolder, encompassing three reproductive tactics, parental, satellite, and sneaker. The parental life history is fixed, whereas individuals who enter the cuckolder life history transition from sneaker to satellite tactic as they grow. For this study, we used RNAseq to characterize the brain transcriptome of...

Data from: Temporal genetic stability in natural populations of the waterflea Daphnia magna in response to strong selection pressure

Luisa Orsini, Hollie Marshall, Maria Cuenca Cambronero, Anurag Chaturvedi, Kelley W. Thomas, Michael E. Pfrender, Katina I. Spanier & Luc De Meester
Studies monitoring changes in genetic diversity and composition through time allow a unique understanding of evolutionary dynamics and persistence of natural populations. However, such studies are often limited to species with short generation times that can be propagated in the laboratory or few exceptional cases in the wild. Species that produce dormant stages provide powerful models for the reconstruction of evolutionary dynamics in the natural environment. A remaining open question is to what extent dormant...

Data from: Benefit of transferred mutations is better predicted by the fitness of recipients than by their ecological or genetic relatedness

Yinhua Wang, Carolina Diaz Arena, Daniel M. Stoebel, Kenneth M. Flynn, Ethan Knapp, Marcus M. Dillon, Andrea Wunsche, Philip J. Hatcher, Francisco B.-G. Moore, Vaughn S. Cooper & Tim F. Cooper
The effect of a mutation depends on its interaction with the genetic background in which it is assessed. Studies in experimental systems have demonstrated that such interactions are common among beneficial mutations and often follow a pattern consistent with declining evolvability of more fit genotypes. However, these studies generally examine the consequences of interactions between a small number of focal mutations. It is not clear, therefore, that findings can be extrapolated to natural populations, where...

Data from: Diverse phenotypic and genetic responses to short-term selection in evolving Escherichia coli populations

Marcus M. Dillon, Nicholas P. Rouillard, Brian Van Dam, Romain Gallet & Vaughn S. Cooper
Beneficial mutations fuel adaptation by altering phenotypes that enhance the fit of organisms to their environment. However, the phenotypic effects of mutations often depend on ecological context, making the distribution of effects across multiple environments essential to understanding the true nature of beneficial mutations. Studies that address both the genetic basis and ecological consequences of adaptive mutations remain rare. Here, we characterize the direct and pleiotropic fitness effects of a collection of 21 first-step beneficial...

Data from: Synchrony in small mammal community dynamics across a forested landscape

Ryan B. Stephens, Daniel J. Hocking, Mariko Yamasaki & Rebecca J. Rowe
Long-term studies at local scales indicate that fluctuations in abundance among trophically similar species are often temporally synchronized. Complementary studies on synchrony across larger spatial extents are less common, as are studies that investigate the subsequent impacts on community dynamics across the landscape. We investigate the impact of species population fluctuations on concordance in community dynamics for the small mammal fauna of the White Mountain National Forest, USA. Hierarchical open population models, which account for...

Data from: Characterization of a male reproductive transcriptome for Peromyscus eremicus (Cactus mouse)

Lauren L. Kordonowy, Matthew D. MacManes & Michael B. Eisen
Rodents of the genus Peromyscus have become increasingly utilized models for investigations into adaptive biology. This genus is particularly powerful for research linking genetics with adaptive physiology or behaviors, and recent research has capitalized on the unique opportunities afforded by the ecological diversity of these rodents. Well characterized genomic and transcriptomic data is intrinsic to explorations of the genetic architecture responsible for ecological adaptations. Therefore, this study characterizes the transcriptome of three male reproductive tissues...
