Data from: Host-adapted aphid populations differ in their migratory patterns and capacity to colonize crops

Sanford D. Eigenbrode, Thomas S. Davis, Jennifer R. Adams, Lisette P. Waits, David Hawthorne & Damon S. Husebye
Although phytophagous insects can vary genetically in host use and exhibit long-range movements, the combined implications of these phenomena for pest management have received limited attention. To address this, we surveyed the genetic diversity of pea aphid Acyrthosiphon pisum using twelve microsatellite loci and assessed host association patterns and annual movement from a putative source region (Columbia River Basin) to the Palouse region of northern Idaho and western Washington, where the aphid is a pest...

Data from: Describing a developing hybrid zone between red wolves and coyotes in eastern North Carolina, USA

Justin H. Bohling, Justin Dellinger, Justin N. McVey, David T. Cobb, Christopher E. Moorman, Lisette P. Waits & Justin M. McVey
When hybridizing species come into contact, understanding the processes that regulate their interactions can help predict the future outcome of the system. This is especially relevant in conservation situations where human activities can influence hybridization dynamics. We investigated a developing hybrid zone between red wolves and coyotes in North Carolina, USA to elucidate patterns of hybridization in a system heavily managed for preservation of the red wolf genome. Using noninvasive genetic sampling of scat, we...

Data from: Climatic thresholds shape northern high-latitude fire regimes and imply vulnerability to future climate change

Adam M. Young, Philip E. Higuera, Paul A. Duffy & Feng Sheng Hu
Boreal forests and arctic tundra cover 33% of global land area and store an estimated 50% of total soil carbon. Because wildfire is a key driver of terrestrial carbon cycling, increasing fire activity in these ecosystems would likely have global implications. To anticipate potential spatiotemporal variability in fire-regime shifts, we modeled the spatially explicit 30-yr probability of fire occurrence as a function of climate and landscape features (i.e. vegetation and topography) across Alaska. Boosted regression...

Data from: Mixed population genomics support for the central marginal hypothesis across the invasive range of the cane toad (Rhinella marina) in Australia

Daryl R. Trumbo, Brendan Epstein, Paul A. Hohenlohe, Ross A. Alford, Lin Schwarzkopf & Andrew Storfer
Understanding factors that cause species' geographic range limits is a major focus in ecology and evolution. The central marginal hypothesis (CMH) predicts that species cannot adapt to conditions beyond current geographic range edges because genetic diversity decreases from core to edge due to smaller, more isolated edge populations. We employed a population genomics framework using 24 235–33 112 SNP loci to test major predictions of the CMH in the ongoing invasion of the cane toad...

Data from: Adaptive divergence despite strong genetic drift: genomic analysis of the evolutionary mechanisms causing genetic differentiation in the island fox (Urocyon littoralis)

W. Chris Funk, Robert E. Lovich, Paul A. Hohenlohe, Courtney A. Hofman, Scott A. Morrison, T. Scott Sillett, Cameron K. Ghalambor, Jesús E. Maldonado, Torben C. Rick, Mitch D. Day, Nicholas R. Polato, Sarah W. Fizpatrick, Timothy J. Coonan, Kevin R. Crooks, Adam Dillon, David K. Garcelon, Julie L. King, Christina L. Boser, Nicholas Gould, William F. Andelt & Sarah W. Fitzpatrick
The evolutionary mechanisms generating the tremendous biodiversity of islands have long fascinated evolutionary biologists. Genetic drift and divergent selection are predicted to be strong on islands and both could drive population divergence and speciation. Alternatively, strong genetic drift may preclude adaptation. We conducted a genomic analysis to test the roles of genetic drift and divergent selection in causing genetic differentiation among populations of the island fox (Urocyon littoralis). This species consists of six subspecies, each...

Data from: Rapid evolutionary response to a transmissible cancer in Tasmanian devils

Brendan Epstein, Menna Jones, Rodrigo Hamede, Sarah Hendricks, Hamish McCallum, Elizabeth P. Murchison, Barbara Schönfeld, Cody Wiench, Paul Hohenlohe & Andrew Storfer
Although cancer rarely acts as an infectious disease, a recently emerged transmissible cancer in Tasmanian devils (Sarcophilus harrisii) is virtually 100% fatal. Devil facial tumour disease (DFTD) has swept across nearly the entire species’ range, resulting in localized declines exceeding 90% and an overall species decline of more than 80% in less than 20 years. Despite epidemiological models that predict extinction, populations in long-diseased sites persist. Here we report rare genomic evidence of a rapid,...

Data from: Small RNAs from a big genome: the piRNA pathway and transposable elements in the salamander species Desmognathus fuscus

Mercedita J. Madison-Villar, Cheng Sun, Nelson C. Lau, Matthew L. Settles & Rachel Lockridge Mueller
Most of the largest vertebrate genomes are found in salamanders, a clade of amphibians that includes 686 species. Salamander genomes range in size from 14 to 120 Gb, reflecting the accumulation of large numbers of transposable element (TE) sequences from all three TE classes. Although DNA loss rates are slow in salamanders relative to other vertebrates, high levels of TE insertion are also likely required to explain such high TE loads. Across the Tree of...

Data from: Identifying cryptic diversity with predictive phylogeography

Anahí Espíndola, Megan Ruffley, Megan L. Smith, Bryan C. Carstens, David C. Tank & Jack Sullivan
Identifying units of biological diversity is a major goal of organismal biology. An increasing literature has focused on the importance of cryptic diversity, defined as the presence of deeply diverged lineages within a single species. While most discoveries of cryptic lineages proceed on a taxon-by-taxon basis, rapid assessments of biodiversity are needed to inform conservation policy and decision-making. Here, we introduce a predictive framework for phylogeography that allows rapidly identifying cryptic diversity. Our approach proceeds...

Data from: Adding biotic complexity alters the metabolic benefits of mutualism

William R. Harcombe, Alex Betts, Jason W. Shapiro & Christopher J. Marx
Mutualism is ubiquitous in nature and plays an integral role in most communities. To predict the eco-evolutionary dynamics of mutualism it is critical to extend classic pair-wise analysis to include additional species. We investigated the effect of adding a third species to a pair-wise mutualism in a spatially structured environment. We tested the hypotheses that selection for costly excretions in a focal population (i) decreases when an exploiter is added (ii) increases when a third...

Data from: Elevated CO2 and temperature increase soil C losses from a soybean-maize ecosystem

Christopher K. Black, Sarah C. Davis, Tara W. Hudiburg, Carl J. Bernacchi & Evan H. DeLucia
Warming temperatures and increasing CO2 are likely to have large effects on the amount of carbon stored in soil, but predictions of these effects are poorly constrained. We elevated temperature (canopy: +2.8 °C; soil growing season: +1.8 °C; soil fallow: +2.3 °C) for 3 years within the 9th–11th years of an elevated CO2 (+200 ppm) experiment on a maize–soybean agroecosystem, measured respiration by roots and soil microbes, and then used a process-based ecosystem model (DayCent)...

Data from: Network analyses reveal intra- and interspecific differences in behaviour when passing a complex migration obstacle

Mark A. Kirk & Christopher C. Caudill
1. Network theory offers new perspective on movement data by evaluating the relationships between animal movements (links) and detection locations (nodes) in spatially complex systems, including human-altered landscapes. 2. We applied network analyses to intra- and interspecific movement patterns in the migration behaviour and dam passage success of two anadromous fish species, Pacific lamprey Entosphenus tridentatus Gairdner and Chinook salmon Oncorhynchus tshawytscha Walbaum, when moving through a large multi-fishway hydroelectric project (Bonneville Dam, USA). 3....

Data from: The ecology of an adaptive radiation of three-spined stickleback from North Uist, Scotland

Isabel S. Magalhaes, Daniele D'Agostino, Paul A. Hohenlohe & Andrew D. C. MacColl
There has been a large focus on the genetics of traits involved in adaptation, but knowledge of the environmental variables leading to adaptive changes is surprisingly poor. Combined use of environmental data with morphological and genomic data should allow us to understand the extent to which patterns of phenotypic and genetic diversity within a species can be explained by the structure of the environment. Here, we analyse the variation of populations of three-spined stickleback from...

Data from: Life in the fat lane: seasonal regulation of insulin sensitivity, food intake, and adipose biology in brown bears

Kimberly S. Rigano, Jamie L. Gehring, Brandon D. Evans Hutzenbiler, Annie V. Chen, O. Lynne Nelson, Chantal A. Vella, Charles T. Robbins & Heiko T. Jansen
Grizzly bears (Ursus arctos horribilis) have evolved remarkable metabolic adaptations including enormous fat accumulation during the active season followed by fasting during hibernation. However, these fluctuations in body mass do not cause the same harmful effects associated with obesity in humans. To better understand these seasonal transitions, we performed insulin and glucose tolerance tests in captive grizzly bears, characterized the annual profiles of circulating adipokines, and tested the anorectic effects of centrally administered leptin at...

Data from: Vive la résistance: genome-wide selection against introduced alleles in invasive hybrid zones

Ryan P. Kovach, Brian K. Hand, Paul A. Hohenlohe, Ted F. Cosart, Matthew C. Boyer, Helen H. Neville, Clint C. Muhlfeld, Stephen J. Amish, Kellie Carim, Shawn R. Narum, Winsor H. Lowe, Fred W. Allendorf & Gordon Luikart
Evolutionary and ecological consequences of hybridization between native and invasive species are notoriously complicated because patterns of selection acting on non-native alleles can vary throughout the genome and across environments. Rapid advances in genomics now make it feasible to assess locus-specific and genome-wide patterns of natural selection acting on invasive introgression within and among natural populations occupying diverse environments. We quantified genome-wide patterns of admixture across multiple independent hybrid zones of native westslope cutthroat trout...

Data from: Quantifying the coevolutionary potential of multistep immune defenses

Scott Landis Nuismer & Mark F. Dybdahl
Coevolutionary models often assume host infection by parasites depends on a single bout of molecular recognition. As detailed immunological studies accumulate, however, it becomes increasingly apparent that the outcome of host-parasite interactions more generally depends on complex multiple step infection processes. For example, in plant and animal innate immunity, recognition steps are followed by downstream effector steps that kill recognized parasites, with the outcome depending on an escalatory molecular arms race. Here, we explore the...

Data from: Bat communities respond positively to large-scale thinning of forest regrowth

Rachel V. Blakey, Brad S. Law, Richard T. Kingsford, Jakub Stoklosa, Patrick Tap & Kelly Williamson
Over half of the world's forests are secondary regrowth and support considerable biodiversity. Thinning of these forests is a widespread management practice that can affect forest species, including echolocating bats and their prey. We compared total activity of 11 bat taxa, foraging activity of six bat guilds and biomass of 11 insect orders across four forest thinning categories in managed remnant eucalypt forests in south-eastern Australia: unthinned regrowth, forest thinned recently (0–4 years) and in...

Data from: Variability of Symbiodinium communities in waters, sediments, and corals of thermally distinct reef pools in American Samoa

Ross Cunning, Denise M. Yost, Marisa L. Guarinello, Hollie M. Putnam & Ruth D. Gates
Reef-building corals host assemblages of symbiotic algae (Symbiodinium spp.) whose diversity and abundance may fluctuate under different conditions, potentially facilitating acclimatization to environmental change. The composition of free-living Symbiodinium in reef waters and sediments may also be environmentally labile and may influence symbiotic assemblages by mediating supply and dispersal. The magnitude and spatial scales of environmental influence over Symbiodinium composition in different reef habitat compartments are, however, not well understood. We used pyrosequencing to compare...
