Data from: Morphological and functional maturity of the oral jaws covary with offspring size in Trinidadian guppies

Terry R. Dial, Luz Patricia Hernandez & Elizabeth L. Brainerd
Large size of individual offspring is routinely selected for in highly competitive environments, such as in low-predation populations of the Trinidadian guppy (Poecilia reticulata). Large guppy offspring outcompete their smaller conspecifics, but the functional mechanisms underlying this advantage are unknown. We measured jaw kinematics during benthic feeding and cranial musculoskeletal morphologies in neonates and juveniles from five populations of Trinidadian guppy and found that both kinematics and morphologies vary substantially with neonatal size. Rotation at...

Data from: The oceanic biological pump: rapid carbon transfer to depth at continental margins during winter

Laurenz Thomsen, Jacopo Aguzzi, Corrado Costa, Fabio De Leo, Andrea Ogston & Autun Purser
The oceanic biological pump is responsible for the important transfer of CO2-C as POC “Particulate Organic Carbon” to the deep sea. It plays a decisive role in the Earth’s carbon cycle and significant effort is spent to quantify its strength. In this study we used synchronized daily time-series data of surface chlorophyll-a concentrations from the NASA’s MODIS satellite in combination with hourly to daily observations from sea surface buoys and from an Internet Operated Vehicle...

Data from: Precipitation alters interactions in a grassland ecological community

Nicolas Deguines, Justin S. Brashares & Laura R. Prugh
Climate change is transforming precipitation regimes world-wide. Changes in precipitation regimes are known to have powerful effects on plant productivity, but the consequences of these shifts for the dynamics of ecological communities are poorly understood. This knowledge gap hinders our ability to anticipate and mitigate the impacts of climate change on biodiversity. Precipitation may affect fauna through direct effects on physiology, behaviour or demography, through plant-mediated indirect effects, or by modifying interactions among species. In...

Data from: History dependence in insect flight decisions during odor tracking

Rich Pang, Floris Van Breugel, Michael Dickinson, Jeffrey A. Riffell & Adrienne Fairhall
Natural decision-making often involves extended decision sequences in response to variable stimuli with complex structure. As an example, many animals follow odor plumes to locate food sources or mates, but turbulence breaks up the advected odor signal into intermittent filaments and puffs. This scenario provides an opportunity to ask how animals use sparse, instantaneous, and stochastic signal encounters to generate goal-oriented behavioral sequences. Here we examined the trajectories of flying fruit flies (Drosophila melanogaster) and...

We provide here the data used in analysis of 3 test cases, presented in the manuscript "Ecological insights from three decades of animal movement tracking across a changing Arctic". We utilized the new Arctic Animal Movement Archive (AAMA), a growing collection of 201 standardized terrestrial and marine animal tracking studies from 1991–present. The AAMA supports public data discovery, preserves fundamental baseline data for the future, and facilitates efficient, collaborative data analysis. With three AAMA-based case...

Turbulence-spurred settlement: Deciphering a newly recognized class of larval response

Matthew Ferner
Overview: With this award the investigators will explore a habitat-scale oceanographic process that has the potential to integrate studies of larval delivery with an understanding of how larvae respond to substrate-associated cues. This work will build on published and preliminary data indicating that turbulent shear characteristic of high-energy near shore environments primes larvae to initiate settlement and to transform into the juvenile stage. These prior findings suggest that: 1) Because turbulence intensity varies predictably as...

Level and spatial pattern of overstory retention impose tradeoffs for regenerating and retained trees

Charles Halpern & Lauren Urgenson
Variable retention (VR) has been adopted globally as an alternative to more intensive forms of regeneration harvest. By retaining live trees within harvest units, VR seeks balance among the commodity, ecological, and aesthetic values of managed forests. Achieving these multiple, often competing objectives requires an understanding of how level and spatial pattern of retention shape the abundance, growth, and mortality of regenerating and retained trees. Using long-term (18-19 yr) data from a regional-scale VR experiment,...

Data from: Phosphorus limitation does not drive loss of bony lateral plates in freshwater stickleback (Gasterosteus aculeatus)

Sophie L. Archambeault, Daniel J. Durston, Alex Wan, Rana El-Sabaawi, Blake Matthews & Catherine L. Peichel
Connecting the selective forces that drive the evolution of phenotypes to their underlying genotypes is key to understanding adaptation, but such connections are rarely tested experimentally. Threespine stickleback (Gasterosteus aculeatus) are a powerful model for such tests because genotypes that underlie putatively adaptive traits have been identified. For example, a regulatory mutation in the Ectodysplasin (Eda) gene causes a reduction in the number of bony armor plates, which occurs rapidly and repeatedly when marine sticklebacks...

Data from: Gut microbiome critically impacts PCB-induced changes in metabolic fingerprints and the hepatic transcriptome in mice

Joe Lim, Julia Cui, Xueshu Li, Hans-Joachim Lehmler, Dongfang Wang & Haiwei Gu
Polychlorinated biphenyls (PCBs) are ubiquitously detected in the environment and have been linked to metabolic diseases. The liver serves as a central hub for the metabolism of xenobiotics and endogenous metabolites. Gut dysbiosis is recognized as a critical regulator of disease susceptibility, however, little is known regarding how PCBs and gut microbiome interact to modulate the interface between xenobiotic and intermediary metabolism. We hypothesized that the gut microbiome regulates PCBs-mediated changes in the metabolic fingerprints...

Confronting sources of systematic error to resolve historically contentious relationships: a case study using gadiform fishes (Teleostei, Paracanthopterygii, Gadiformes)

Adela Roa-Varon, Rebecca Dikow, Giorgio Carnevale, Luke Tornabene, Carole Baldwin, Chenhong Li & Eric Hilton
Reliable estimation of phylogeny is central to avoid inaccuracy in downstream macroevolutionary inferences. However, limitations exist in the implementation of concatenated and summary coalescent approaches, and Bayesian and full coalescent inference methods may not yet be feasible for computation of phylogeny using complicated models and large datasets. Here, we explored methodological (e.g., optimality criteria, character sampling, model selection) and biological (e.g., heterotachy, branch length heterogeneity) sources of systematic error that can result in biased or...

Rapamycin rejuvenates oral health in aging mice

Kristopher Kerns
Periodontal disease is an age-associated disorder clinically defined by periodontal bone loss, inflammation of the specialized tissues that surround and support the tooth, and microbiome dysbiosis. Currently, there is no therapy for reversing periodontal disease, and treatment is generally restricted to preventive measures or tooth extraction. The FDA-approved drug rapamycin slows aging and extends lifespan in multiple organisms, including mice. Here we demonstrate that short-term treatment with rapamycin rejuvenates the aged oral cavity of elderly...

Fluid-preserved fishes are one solution for assessing historical change in fish trophic level

Rachel Welicky, Terry Rolfe, Karrin Leazer, Katherine Pearson Masklenikov, Luke Tornabene, Gordon Holtgrieve & Chelsea Wood
There are few resources available for assessing historical change in fish trophic dynamics, but specimens held in natural history collections could serve as this resource. In contemporary trophic ecology studies, trophic and source information can be obtained from compound-specific stable nitrogen isotope analysis (CSIA-AA-N). Can this method yield reliable trophic information from chemically-altered fish specimens held in natural history collections? We tested whether CSIA-AA-N can be used on fluid-preserved specimens by experimentally subjecting specimens to...
