Cross-seasonal effects in the American Woodcock: conditions prior to fall migration relate to migration strategy and its implications for conservationClayton Graham, Tanner Steeves & Scott McWilliams
How post-breeding habitat quality and body composition of migratory birds carry over to influence fall migration strategies and residency merits consideration when creating cross-seasonal conservation plans, especially in breeding populations that are partial migrants. We assessed the influence of post-breeding habitat quality on departure body composition and fall migration patterns in a southern New England breeding population of American Woodcock (Scolopax minor). Woodcock that overwintered near breeding areas (n=5) had less fat upon capture in...
Hypoxia-induced predation refuge for northern quahogs (Mercenaria mercenaria) in a temperate estuaryBryan Galligan, Yoel Stuart, M. Conor McManus & Heather Stoffel
Oxygen depletion in estuaries and coastal waters is often associated with reduced biodiversity, coastal dead zones, and the loss of important ecosystem services. However, some species can benefit from low oxygen conditions due to the indirect effects these conditions have on trophic relationships. In Narragansett Bay, Rhode Island, U.S.A., northern quahogs (Mercenaria mercenaria) reach their highest densities in the areas of the Bay most prone to oxygen depletion. One line of evidence suggests that suboxic...
Essential amino acid requirements of granivorous and omnivorous songbirds and the provision of natural foodsLillie Langlois & Scott McWilliams
Wild birds must consume certain amounts of protein and an appropriate balance of amino acids while inhabiting environments where foods often differ in the quantity and quality of available protein. The requirements for amino acids are well documented for domestic bird species but are largely unknown for wild birds, which makes it impossible to reliably assess the nutritional adequacy of foods eaten by wild birds. We measured the maintenance requirements for three essential amino acids...

Data from: Conservation and convergence of genetic architecture in the adaptive radiation of anolis lizardsJoel W. McGlothlin, Megan E. Kobiela, Helen V. Wright, Jason J. Kolbe, Jonathan B. Losos & Edmund D. Brodie
The G matrix, which quantifies the genetic architecture of traits, is often viewed as an evolutionary constraint. However, G can evolve in response to selection and may also be viewed as a product of adaptive evolution. Convergent evolution of G in similar environments would suggest that G evolves adaptively, but it is difficult to disentangle such effects from phylogeny. Here, we use the adaptive radiation of Anolis lizards to ask whether convergence of G accompanies...
Interrogating genomic data in the phylogenetic placement of treeshrews reveals potential sources of conflictAlexander Knyshov, Yana Hrytsenko, Robert Literman & Rachel S. Schwartz
The position of some taxa on the Tree of Life remains controversial despite the increase in genomic data used to infer phylogenies. While analyzing large datasets alleviates stochastic errors, it does not prevent systematic errors in inference, caused by both biological (e.g., incomplete lineage sorting, hybridization) and methodological (e.g., incorrect modeling, erroneous orthology assessments) factors. In this study, we systematically investigated factors that could result in these controversies, using the treeshrew (Scandentia, Mammalia) as a...
Time is a fundamental component of ecological processes. How animal behavior changes over time has been explored through well-known ecological theories like niche partitioning and predator-prey dynamics. Yet, changes in animal behavior within the shorter 24-hour light-dark cycle have largely gone unstudied. Understanding if an animal can adjust their temporal activity to mitigate or adapt to environmental change has become a recent topic of discussion and is important for effective wildlife management and conservation. While...
Dataset and codes for: Partitioning the apparent temperature sensitivity between autotrophic and heterotrophic protistsBingzhang Chen, David Montagnes, Qing Wang, Hongbin Liu & Susanne Menden-Deuer
Conventional analyses suggest the metabolism of heterotrophs is thermally more sensitive than that of autotrophs, implying that warming leads to pronounced trophodynamic imbalances. However, these analyses inappropriately combine within- and across-taxa trends. We present a novel mathematic framework to separate these, revealing that the higher temperature sensitivity of heterotrophs is mainly caused by within-taxa responses which account for 92% of the difference between autotrophic and heterotrophic protists. This dataset contains both the datasets and R...
To examine phylogenetic heterogeneity in turtle evolution, we collected thousands of high-confidence single-copy orthologs from 19 genome assemblies representative of extant turtle diversity and estimated a phylogeny with multispecies coalescent and concatenated partitioned methods. We also collected next-generation sequences from 26 turtle species and assembled millions of biallelic markers to reconstruct phylogenies based on annotated regions from the western painted turtle (Chrysemys picta bellii) genome (coding regions, introns, untranslated regions, intergenic, and others). We then...
Current methods to model species habitat use through space and diel time are limited. Development of such models is critical when considering rapidly changing habitats where species are forced to adapt to anthropogenic change, often by shifting their diel activity across space. We use an occupancy modeling framework to specify the multi-state diel occupancy model (MSDOM), which can evaluate species diel activity against continuous response variables which may impact diel activity within and across seasons...
Data From: Antibiotic treatment ameliorates the impact of stony coral tissue loss disease (SCTLD) on coral communitiesGraham Forrester, Laura Arton & Argel Horton
Stony coral tissue loss disease has spread widely in the Caribbean and causes substantial changes to coral community composition because of its broad host range and high fatality rate. To reduce SCTLD impacts, intervention programs throughout the region have divers treating corals with antibiotics. We assessed the effect of antibiotic treatment in the British Virgin Islands by comparing coral communities at 13 treated sites to those at 13 untreated sites. The prevalence of white syndromes...
An improved earthquake catalog during the 2018 Kilauea eruption from combined onshore and offshore seismic arraysXiaoZhuo Wei, Yang Shen, Jacqueline Caplan‐Auerbach & Julia K. Morgan
The Island of Hawai'i was formed by repeated eruptions of basalts at an oceanic hotspot. Kilauea, the youngest among the subaerial volcanoes of the island, erupted intensely in 2018. The eruption provided an opportunity to look into the mechanisms that operate at the volcano and associated earthquake activities, as it was recorded simultaneously, for the first time, by onshore and offshore seismometers. We used most of the publicly available seismic data during the eruption period,...
Host-parasite interactions between a copepod (Pharodes tortugensis) and small reef-associated gobies (Coryphopterus) in the British Virgin IslandsGraham Forrester & Rachel Finley
The effects of parasitic copepods on free-living hosts are infrequently documented, and the copepod Pharodes tortugensis has remained virtually unstudied since described. For the first time, we document its host range in the British Virgin Islands (BVI), the prevalence and intensity of infections on wild hosts, and its impacts on host morphology and performance. Infections were observed on four benthic gobies in the BVI (Coryphopterus glaucofraenum, C. venezuelae, C. dicrus and C. eidolon) but not...
Data associated with: Minor genetic consequences of a major mass mortality: Short-term effects in Pisaster ochraceusLauren Schiebelhut, Melina Giakoumis, Rita Castilho, Paige Duffin, Jonathan Puritz, John Wares, Gary Wessel & Michael Dawson
Mass mortality events (MMEs) are increasing globally in frequency and magnitude, largely due to human-induced change. The effects of these MMEs, both in the long- and short-term, are of imminent concern because of their ecosystem impacts. Genomic data can be used to reveal some of the population-level changes associated with MMEs. Here, we use reduced-representation sequencing to identify potential short-term genetic impacts of an MME associated with a sea star wasting (SSW) outbreak. We tested...
