Data from: Detrital shadows: estuarine food web connectivity depends on fluvial influence and consumer feeding mode

Emily Howe, Charles A. Simenstad & Andrea Ogston
We measured the influence of landscape setting on estuarine food web connectivity in five macrotidal Pacific Northwest estuaries across a gradient of freshwater influence. We used stable isotopes (δ13C, δ15N, δ34S) in combination with a Bayesian mixing model to trace primary producer contributions to suspension- and deposit-feeding bivalve consumers (Mytilus trossulus and Macoma nasuta) transplanted into three estuarine vegetation zones: emergent marsh, mudflat, Japanese eelgrass (Zostera japonica), and native eelgrass (Zostera marina). Fluvial discharge and...

Data from: Evolution of plasticity and adaptive responses to climate change along climate gradients

Joel G. Kingsolver & Lauren B. Buckley
The relative contributions of phenotypic plasticity and adaptive evolution to the responses of species to recent and future climate change are poorly understood. We combine recent (1960–2010) climate and phenotypic data with microclimate, heat balance, demographic and evolutionary models to address this issue for a montane butterfly, Colias eriphyle, along an elevational gradient. Our focal phenotype, wing solar absorptivity, responds plastically to developmental (pupal) temperatures and plays a central role in thermoregulatory adaptation in adults....

Data from: Congruent population structure across paralogous and non-paralogous loci in Salish Sea chum salmon (Oncorhynchus keta)

Ryan K. Waples, Jim E. Seeb & Lisa W. Seeb
Whole genome duplications are major evolutionary events with a lasting impact on genome structure. Duplication events complicate genetic analyses as paralogous sequences are difficult to distinguish; consequently paralogs are often excluded from studies. The effects of an ancient whole genome duplication (approximately 88MYA) are still evident in salmonids through the persistence of numerous paralogous gene sequences and partial tetrasomic inheritance. We use restriction site-associated DNA sequencing (RADseq) on ten collections of chum salmon from the...

Data from: Geometric morphometric analyses of worn cheek teeth help identify extant and extinct gophers (Rodentia: Geomyidae)

Jonathan J. M. Calede & Jennifer W. Glusman
Studies of the biostratigraphy and palaeoecology of fossil vertebrate assemblages require large samples of accurately identified specimens. Such analyses can be hampered by the inability to assign isolated and worn remains to specific taxa. Entoptychine gophers are a diverse group of burrowing rodents found in Oligo-Miocene deposits of the western United States. In both entoptychines and their extant relatives the geomyines, diagnostic characters of the occlusal surface of the teeth are modified with wear, making...

Data from: A resource on latitudinal and altitudinal clines of ecologically relevant phenotypes of the Indian Drosophila

Subhash Rajpurohit, Xiaqing Zhao & Paul S. Schmidt
The unique geography of the Indian subcontinent has provided diverse natural environments for a variety of organisms. In this region, many ecological indices such as temperature and humidity vary predictably as a function of both latitude and altitude; these environmental parameters significantly affect fundamental dynamics of natural populations. Indian drosophilids are diverse in their geographic distribution and climate tolerance, possibly as a result of climatic adaptation. These associations with environmental parameters are further reflected in...

Data from: Form–function relationships in a marine foundation species depend on scale: a shoot to global perspective from a distributed ecological experiment

Jennifer L. Ruesink, John J. Stachowicz, Pamela L. Reynolds, Christoffer Boström, Mathieu Cusson, James Douglass, Johan Eklöf, Aschwin H. Engelen, Masakazu Hori, Kevin Hovel, Katrin Iken, Per-Olav Moksnes, Masahiro Nakaoka, Mary I. O'Connor, Jeanine L. Olsen, Erik E. Sotka, Matthew A. Whalen & Emmett J. Duffy
Form-function relationships in plants underlie their ecosystem roles in supporting higher trophic levels through primary production, detrital pathways, and habitat provision. For widespread, phenotypically-variable plants, productivity may differ not only across abiotic conditions, but also from distinct morphological or demographic traits. A single foundation species, eelgrass (Zostera marina), typically dominates north temperate seagrass meadows, which we studied across 14 sites spanning 32-61° N latitude and two ocean basins. Body size varied by nearly two orders...

Data from: House sparrows offset the physiological trade-off between immune response and feather growth by adjusting foraging behavior

Miriam Ben-Hamo, Cynthia Downs, Darren Burns, Berry Pinshow, Cynthia J. Downs & Darren J. Burns
Growing feathers and mounting immune responses are both energetically costly for birds. According to the life history trade-off hypothesis, it has been posited that the costs of feather growth lead to temporal isolation between molt and other expensive activities, reproduction for example. In contrast to life cycle events, the need to mount an immune response can occur at any time, including during feather growth. Thus, we hypothesized that mounting an immune response during feather growth...

Data from: Evaluating mechanisms of diversification in a Guineo-Congolian tropical forest frog using demographic model selection

Daniel M. Portik, Adam D. Leaché, Danielle Rivera, Michael F. Barej, Marius Burger, Mareike Hirschfeld, Mark-Oliver Rödel, David C. Blackburn & Matthew K. Fujita
The accumulation of biodiversity in tropical forests can occur through multiple allopatric and parapatric models of diversification, including forest refugia, riverine barriers and ecological gradients. Considerable debate surrounds the major diversification process, particularly in the West African Lower Guinea forests, which contain a complex geographic arrangement of topographic features and historical refugia. We used genomic data to investigate alternative mechanisms of diversification in the Gaboon forest frog, Scotobleps gabonicus, by first identifying population structure and...

Data from: Assessing differences between ancestral recombination graphs

Mary K. Kuhner & Jon Yamato
Ancestral recombination graphs (ARGs) represent the history of portions of a genome with recombination. Attempts to infer ARGs have been hampered by the lack of an ARG comparison metric which could be used to measure how well inference succeeded. We propose a simple ARG comparison framework based on averaging standard tree comparison measures across sites. Using simulated data we show that this framework, instantiated with an appropriate tree comparison measure, can distinguish better from worse...
