Data from: Sensory drive does not explain reproductive character displacement of male acoustic signals in the Upland Chorus Frog (Pseudacris feriarum)

Emily Claire Moriarty Lemmon, Jessica Ribado, John H. Malone & Emily Moriarty Lemmon
Biotic and abiotic factors have been proposed to explain patterns of reproductive character displacement, but which factor is most important to character displacement of acoustic signals is not clear. Male vocalizations of the frog Pseudacris feriarum are known to undergo reproductive character displacement in areas of sympatry with P. brimleyi and P. nigrita. Despite evidence for reinforcement as an important mechanism, local adaptation via sensory drive might explain this pattern because Pseudacris breed in different...

Data from: Spatially heterogeneous impact of climate change on small mammals of montane California

Kevin C. Rowe, Karen M. C. Rowe, Morgan W. Tingley, Michelle S. Koo, James L. Patton, Christopher J. Conroy, John D. Perrine, Steven R. Beissinger & Craig Moritz
Resurveys of historical collecting localities have revealed range shifts, primarily leading edge expansions, which have been attributed to global warming. However, there have been few spatially replicated community-scale resurveys testing whether species' responses are spatially consistent. Here we repeated early twentieth century surveys of small mammals along elevational gradients in northern, central and southern regions of montane California. Of the 34 species we analysed, 25 shifted their ranges upslope or downslope in at least one...

Data from: Genome- and transcriptome-assisted development of nuclear insertion/deletion markers for Calanus species (Copepoda: Calanoida) identification

Irina Smolina, Spyros Kollias, Marloes Poortvliet, Torkel Nielsen, Penelope Lindeque, Claudia Castellani, Eva Møller, Leocadio Blanco-Bercial & Galice Hoarau
Copepods of the genus Calanus are key zooplankton species in temperate to arctic marine ecosystems. Despite their ecological importance, species identification remains challenging. Furthermore, the recent report of hybrids among Calanus species highlights the need for diagnostic nuclear markers in order to efficiently identify parental species and hybrids. Using Next Generation Sequencing analysis of both the genome and transcriptome from two sibling species, C. finmarchichus and C. glacialis, we developed a panel of 12 nuclear...

Data from: Population of origin and environment interact to determine oomycete infections in spotted salamander populations

Mark C. Urban, Louise A. Lewis, Karolina Fučíková & Alexis Cordone
Spatial variation in disease risk in wild populations can depend both on environmental and genetic factors. Understanding the various contributions of each factor requires experimental manipulation of both the environment and genetic composition of populations under natural field conditions. We first examined natural patterns of oomycete composition and infection in the eggs of 13 populations of the spotted salamander Ambystoma maculatum. We then performed a fully factorial field transplant of the eggs of six populations...

Data from: Mitochondrial phylogenomics of early land plants: mitigating the effects of saturation, compositional heterogeneity, and codon-usage bias

Yang Liu, Cymon J. Cox, Wei Wang & Bernard Goffinet
Phylogenetic analyses using concatenation of genomic-scale data have been seen as the panacea to resolving the incongruences among inferences from few or single genes. However, phylogenomics may also suffer from systematic errors, due to the, perhaps cumulative, effects of saturation, among-taxa compositional (GC content) heterogeneity, or codon-usage bias plaguing the individual nucleotide loci that are concatenated. Here we provide an example of how these factors affect the inferences of the phylogeny of early land plants...

Data from: Diversification and asymmetrical gene flow across time and space: lineage sorting and hybridization in polytypic barking frogs

Jeffrey W. Streicher, Thomas J. Devitt, Caren S. Goldberg, John H. Malone, Heath Blackmon & Matthew K. Fujita
Young species complexes that are widespread across ecologically disparate regions offer important insights into the process of speciation because of their relevance to how local adaptation and gene flow influence diversification. We used mitochondrial DNA and up to 28,152 genome-wide SNPs from polytypic barking frogs (Craugastor augusti complex) to infer phylogenetic relationships and test for the signature of introgressive hybridization among diverging lineages. Our phylogenetic reconstructions suggest (1) a rapid Pliocene-Pleistocene radiation that produced at...

Data from: The global distribution of diet breadth in insect herbivores

Morais, Masashi Murakami … & Lee A. Dyer
Understanding variation in resource specialization is important for progress on issues that include coevolution, community assembly, ecosystem processes, and the latitudinal gradient of species richness. Herbivorous insects are useful models for studying resource specialization, and the interaction between plants and herbivorous insects is one of the most common and consequential ecological associations on the planet. However, uncertainty persists regarding fundamental features of herbivore diet breadth, including its relationship to latitude and plant species richness. Here...

Data from: Degree of host susceptibility in the initial disease outbreak influences subsequent epidemic spread

Paul M. Severns, Laura K. Estep, Kathryn E. Sackett & Christopher C. Mundt
1. Disease epidemics typically begin as an outbreak of a relatively small, spatially explicit population of infected individuals (focus), in which disease prevalence increases and rapidly spreads into the uninfected, at-risk population. Studies of epidemic spread typically address factors influencing disease spread through the at-risk population, but the initial outbreak may strongly influence spread of the subsequent epidemic. 2. We initiated wheat stripe rust Puccinia striiformis f. sp. tritici epidemics to assess the influence of...

Data from: Radial changes in wood specific gravity of tropical trees: inter- and intra-specific variation during secondary succession

Benjamin T. Plourde, Vanessa Boukili, Robin Chazdon, Vanessa K. Boukili & Robin L. Chazdon
Variation in wood specific gravity (WSG) within and across species of tropical trees is poorly studied in relation to vegetation change during tropical forest succession. We investigated WSG of 91 species in eight long-term plots along a successional chronosequence in northeastern Costa Rica. Radial changes in WSG were described by the rate of change (slope) along the stem radius. Significant radial changes were found in 42 of 74 species, with 37 species exhibiting increases from...

Data from: Transcriptome resources for the white-footed mouse (Peromyscus leucopus): new genomic tools for investigating ecologically divergent urban and rural populations

Stephen E. Harris, Rachel J. O'Neill & Jason Munshi-South
Genomic resources are important and attainable for examining evolutionary change in divergent natural populations of non-model species. We utilized two Next Generation Sequencing (NGS) platforms, 454 and SOLiD 5500XL, to assemble low coverage transcriptomes of the white-footed mouse (Peromyscus leucopus), a widespread and abundant native rodent in eastern North America. We sequenced liver mRNA transcripts from multiple individuals collected from urban populations in New York City and rural populations in undisturbed protected areas nearby and...

Data from: The effects of inference method, population sampling and gene sampling on species tree inferences: an empirical study in slender salamanders (Plethodontidae: Batrachoseps)

Elizabeth L. Jockusch, Iñigo Martínez-Solano & Elizabeth K. Timpe
Species tree methods are now widely used to infer the relationships among species from multi-locus datasets. Many methods have been developed, which differ in whether gene and species trees are estimated simultaneously or sequentially, and in how gene trees are used to infer the species tree. While these methods perform well on simulated data, less is known about what impacts their performance on empirical data. We used a dataset including five nuclear genes and one...

Data from: Season-specific and guild-specific effects of anthropogenic landscape modification on metacommunity structure of tropical bats

Laura M. Cisneros, Matthew E. Fagan & Michael R. Willig
1. Fragmentation per se due to human land conversion is a landscape-scale phenomenon. Accordingly, assessment of distributional patterns across a suite of potentially connected communities (i.e. metacommunity structure) is an appropriate approach for understanding the effects of landscape modification, and complements the plethora of fragmentation studies that have focused on local community structure. To date, metacommunity structure within human-modified landscapes has been assessed with regard to nestedness along species richness gradients. This is problematic because...

Data from: No evidence for induction or selection of mutant sodium channel expression in the copepod Acartia husdsonica challenged with the toxic dinoflagellate Alexandrium fundyense

Michael Finiguerra, David E. Avery & Hans G. Dam
Some species in the dinoflagellate genus Alexandrium spp. produce a suite of neurotoxins that block sodium channels, known as paralytic shellfish toxins (PST), which have deleterious effects on grazers. Populations of the ubiquitous copepod grazer Acartia hudsonica that have co-occurred with toxic Alexandrium spp. are better adapted than naïve populations. The mechanism of adaptation is currently unknown. We hypothesized that a mutation in the sodium channel could account for the grazer adaptation. We tested two...
