Data from: Variation in individual temperature preferences, not behavioural fever, affects susceptibility to chytridiomycosis in amphibians

Erin L. Sauer, Rebecca C. Fuller, Corinne L. Richards-Zawacki, Julia Sonn, Jinelle H. Sperry & Jason R. Rohr
The ability of wildlife populations to mount rapid responses to novel pathogens will be critical for mitigating the impacts of disease outbreaks in a changing climate. Field studies have documented that amphibians preferring warmer temperatures are less likely to be infected with the fungal pathogen Batrachochytrium dendrobatidis (Bd). However, it is unclear whether this phenomenon is driven by behavioural fever or natural variation in thermal preference. Here, we placed frogs in thermal gradients, tested for...

Data from: A re‐interpretation of the ambulacral system of Eumorphocystis (Blastozoa, Echinodermata) and its bearing on the evolution of early crinoids

Sarah L. Sheffield & Colin D. Sumrall
Recent debates over the evolutionary relationships of early echinoderms have relied heavily on morphological evidence from the feeding ambulacral system. Eumorphocystis, a Late Ordovician diploporitan, has been a focus in these debates because it bears ambulacral features that show strong morphological similarity to early crinoid arms. Undescribed and well‐preserved specimens of Eumorphocystis from the Bromide Formation (Oklahoma, USA) provide new data illustrating that composite arms supported by a radial plate that bear a triserial arrangement...

Data from: Correlates of rate heterogeneity in avian ecomorphological traits

Angela M. Chira, Christopher R. Cooney, Jen A. Bright, Elliot J.R. Capp, Emma C. Hughes, Chris J.A. Moody, Lara O. Nouri, Zoe K. Varley, Gavin H. Thomas, E. J. R. Capp & C. J. A. Moody
Heterogeneity in rates of trait evolution is widespread, but it remains unclear which processes drive fast and slow character divergence across global radiations. Here, we test multiple hypotheses for explaining rate variation in an ecomorphological trait (beak shape) across a globally distributed group (birds). We find low support that variation in evolutionary rates of species is correlated with life history, environmental mutagenic factors, range size, number of competitors, or living on islands. Indeed, after controlling...

Data from: Transcriptome response of the foundation plant Spartina alterniflora to the Deepwater Horizon oil spill

Mariano F Alvarez, Julie Ferreira De Carvalho, Armel Salmon, Malika L. Ainouche, Armand Cavé-Radet, Abdelhak El Amrani, Tammy E. Foster, Sydney Moyer, Christina L. Richards & Mariano Alvarez
Despite the severe impacts of the Deepwater Horizon oil spill, the foundation plant species Spartina alterniflora proved resilient to heavy oiling, providing an opportunity to identify mechanisms of response to the anthropogenic stress of crude oil exposure. We assessed plants from oil affected and unaffected populations using a custom DNA microarray to identify genome-wide transcription patterns and gene expression networks that respond to crude oil exposure. Additionally, we used T-DNA insertion lines of the model...

Data from: The Phylogeny of the Diploporita: a polyphyletic assemblage of blastozoan echinoderms

Sarah L. Sheffield & Colin D. Sumrall
The phylogenetic relationships of Paleozoic blastozoan echinoderms are poorly understood and many of the traditionally ascribed groups are likely polyphyletic. Diploporitans, those blastozoans with double pore (diplopore) respiratory structures, have never been placed within a rigorous phylogenetic framework and their highly variable morphologies suggest that they do not represent a natural clade. A maximum parsimony phylogenetic analysis, spanning a wide range of diploporitan and related taxa, indicates that diplopore-bearing blastozoans are a polyphyletic grouping and,...

Data from: Past is prologue: host community assembly and the risk of infectious disease over time

Fletcher W. Halliday, Robert W. Heckman, Peter A. Wilfahrt & Charles E. Mitchell
Infectious disease risk is often influenced by host diversity, but the causes are unresolved. Changes in diversity are associated with changes in community structure, particularly during community assembly; therefore, by incorporating change over time, host community assembly may provide a framework to resolve causation. In turn, community assembly can be driven by many processes, including resource enrichment. To test the hypothesis that community assembly causally links host diversity to future disease, we experimentally manipulated host...

Data from: An updated global dataset for diet preferences in terrestrial mammals: testing the validity of extrapolation

Alison M. Gainsbury, Oliver J. S. Tallowin & Shai Meiri
1. Diet is a key trait of an organism’s life history that influences a broad spectrum of ecological and evolutionary processes. Kissling et al. (2014) compiled a species-specific dataset of diet preferences of mammals for 38% of a total of 5364 terrestrial mammalian species assessed for the International Union for Conservation of Nature’s Red List, to facilitate future studies. The authors imputed dietary data for the remaining 62% by using extrapolation from phylogenetic relatives. 2....

Data from: Claw morphometrics in monitor lizards: variable substrate and habitat use correlate to shape diversity within a predator guild

Domenic C. D'Amore, Simon Clulow, J. Sean Doody, David Rhind & Colin R. McHenry
Numerous studies investigate morphology in the context of habitat, and lizards have received particular attention. Substrate usage is often reflected in the morphology of characters associated with locomotion, and, as a result, claws have become well‐studied ecomorphological traits linking the two. The Kimberley predator guild of Western Australia consists of 10 sympatric varanid species. The purpose of this study was to quantify claw size and shape in the guild using geometric morphometrics, and determine whether...

Data from: Parallel evolution of gene classes, but not genes: evidence from Hawai’ian honeycreeper populations exposed to avian malaria

Loren Cassin-Sackett, Taylor E. Callicrate & Robert C. Fleischer
Adaptation in nature is ubiquitous, yet characterizing its genomic basis is difficult because population demographics cause correlations with non-adaptive loci. Introduction events provide opportunities to observe adaptation over known spatial and temporal scales, facilitating the identification of genes involved in adaptation. The pathogen causing avian malaria, Plasmodium relictum, was introduced to Hawai’i in the 1930s and elicited extinctions and precipitous population declines in native honeycreepers. After a sharp initial population decline, the Hawai’i ‘amakihi (Chlorodrepanis...

Data from: Intraspecific predator inhibition, not a prey size refuge, enables oyster population persistence during predator outbreaks

Harriet S. Booth, Timothy J. Pusack, J.Wilson White, Chris D. Stallings, David L. Kimbro, HS Booth, DL Kimbro, TJ Pusack, CD Stallings & JW White
Predators commonly structure natural communities, but predation effects can vary greatly. For example, increasing predator densities may not reduce prey populations as expected if intraspecific predator interactions suppress foraging efficiency or if prey size refuges exist. In northeastern Florida (USA), outbreaks of the predatory crown conch Melongena corona have contributed to declines in oyster populations and the commercial oyster fishery. However, despite expectations of oyster population collapse, reefs have persisted, albeit with reduced adult oyster...

Data from: The evolutionary relationship between beak shape, mechanical advantage, and feeding ecology in modern birds

Guillermo Navalón, Jen A. Bright, Jesús Marugán-Lobón & Emily J. Rayfield
Extensive research on avian adaptive radiations has led to a presumption that beak morphology predicts feeding ecology in birds. However, this ecomorphological relationship has only been quantified in a handful of avian lineages, where associations are of variable strength, and never at a broad macroevolutionary scale. Here, we used shape analysis and phylogenetic comparative methods to quantify the relationships between beak shape, mechanical advantage, and two measures of feeding ecology (feeding behaviour and semi-quantitative dietary...
