Data from: Allometric and trait-based patterns in parasite stoichiometry

Rachel E. Paseka & Rita L. Grunberg
We measured the elemental content (%C, N, and P) and ratios (C:N, C:P, N:P) of a diverse assemblage of parasitic helminths to ask whether taxonomy or traits were related to stoichiometric variation among species. We sampled 27 macroparasite taxa, spanning 4 phyla, infecting vertebrate and invertebrate hosts from freshwater ecosystems in New Jersey. Macroparasites varied widely in elemental content, exhibiting 4.7-fold variation in %N, 4.6-fold variation in %P, and 11.5-fold variation in N:P. Across all...

Background: Lung nodules are a diagnostic challenge, with an estimated yearly incidence of 1.6 million in the United States. This study evaluated the accuracy of an integrated proteomic classifier in identifying benign nodules in patients with a pretest probability of cancer (pCA) ≤ 50%. Methods: A prospective, multicenter observational trial of 685 patients with 8- to 30-mm lung nodules was conducted. Multiple reaction monitoring mass spectrometry was used to measure the relative abundance of two...

Data from: Projecting shifts in thermal habitat for 686 species on the North American continental shelf

James W. Morley, Rebecca L. Selden, Robert J. Latour, Thomas L. Froelicher, Richard J. Seagraves, Malin L. Pinsky & Thomas L. Frölicher
Recent shifts in the geographic distribution of marine species have been linked to shifts in preferred thermal habitats. These shifts in distribution have already posed challenges for living marine resource management, and there is a strong need for projections of how species might be impacted by future changes in ocean temperatures during the 21st century. We modeled thermal habitat for 686 marine species in the Atlantic and Pacific oceans using long-term ecological survey data from...

Data from: Fires in protected areas reveal unforeseen costs of Colombian peace

Dolors Armenteras, Laura Schneider & Liliana María Dávalos
Armed conflict, and its end, can have powerful effects on natural resources, but the influence of war and peace on highly biodiverse tropical forests remains disputed. We found a sixfold increase in fires in protected areas across biodiversity hotspots following guerrilla demobilization in Colombia, and a 52% increase in the probability of per-pixel deforestation within parks for 2018. Peace requires urgent shifts to include real-time forest monitoring, expand programmes to pay for ecosystem services at...

Data from: Caught in the web: spider web architecture affects prey specialization and spider–prey stoichiometric relationships

Lorraine Ludwig, Matthew A. Barbour, Jennifer Guevara, Leticia Avilés & Angélica L. González
1. Quantitative approaches to predator-prey interactions are central to understanding the structure of food webs and their dynamics. Different predatory strategies may influence the occurrence and strength of trophic interactions likely affecting the rates and magnitudes of energy and nutrient transfer between trophic levels, and the stoichiometry of predator-prey interactions. 2. Here, we used spider-prey interactions as a model system to investigate whether different spider web architectures—orb, tangle, and sheet-tangle—affect the composition and diet breadth...

Data from: Using risk of bias domains to identify opportunities for improvement in food- and nutrition-related research: an evaluation of research type and design, year of publication, and source of funding

Esther Myers, James S. Parrott, Patricia Splett, Mei Chung & Deepa Handu
Purpose: This retrospective cross-sectional study aimed to identify opportunities for improvement in food and nutrition research by examining risk of bias (ROB) domains. Methods: Rating were extracted from critical appraisal records for 5675 studies used in systematic reviews conducted by three organizations. Variables were as follows: ROB domains defined by the Cochrane Collaboration (Selection, Performance, Detection, Attrition, and Reporting), publication year, research type (intervention or observation) and specific design, funder, and overall quality rating (positive,...

Data from: Pet problems: biological and economic factors that influence the release of alien reptiles and amphibians by pet owners

Oliver C. Stringham & Julie L. Lockwood
1. The number of alien reptiles and amphibians introduced and established worldwide has been increasing over the last decades. The legal pet trade is the now the dominant pathway by which individuals of these species arrive in their non-native locale. Despite its importance, pet trade pathway specific factors that influence the release (introduction) of exotic reptiles and amphibians have not yet been examined. 2. To address this gap, we set out to identify broad-scale and...

Data from: Genomic signatures of environmental selection despite near-panmixia in summer flounder

Jennifer A. Hoey & Malin L. Pinsky
Rapid environmental change is altering the selective pressures experienced by marine species. While adaptation to local environmental conditions depends on a balance between dispersal and natural selection across the seascape, the spatial scale of adaptation and the relative importance of mechanisms maintaining adaptation in the ocean are not well understood, Here, using population assignment tests, Approximate Bayesian Computation (ABC), and genome scans with double-digest restriction-site associated DNA sequencing data, we evaluated population structure and locus-environment...

Data from: Response of marine communities to local temperature changes

Patrick H. Flanagan, Olaf P. Jensen, James W. Morley & Malin L. Pinsky
As global climate change and variability drive shifts in species’ distributions, ecological communities are being reorganized. One approach to understand community change in response to climate change has been to characterize communities by a collective thermal preference, or Community Temperature Index (CTI), and then to compare changes in CTI with changes in temperature. However, important questions remain about whether and how responsive communities are to changes in their local thermal environments. We used CTI to...

Data from: Costs and benefits of non-random seed release for long distance dispersal in wind-dispersed plant species

Jelle Treep, Monique De Jager, Leandra S. Kuiper, Tomer Duman, Gabriel G. Katul & Merel B. Soons
The dispersal ability of plants is a major factor driving ecological responses to global change. In wind-dispersed plant species, non-random seed release in relation to wind speeds has been identified as a major determinant of dispersal distances. However, little information is available about the costs and benefits of non-random abscission and the consequences of timing for dispersal distances. We asked: 1) To what extent is non-random abscission able to promote long-distance dispersal and what is...

Data from: Ecological mechanisms and phylogeny shape invertebrate stoichiometry: a test using detritus-based communities across Central and South America

Angélica L. González, Régis Céréghino, Olivier Dézerald, Vinicius F. Farjalla, Céline Leroy, Barbara A. Richardson, Michael J. Richardson, Gustavo Q. Romero & Diane S. Srivastava
1. Stoichiometric differences among organisms can affect trophic interactions and rates of nutrient cycling within ecosystems. However, we still know little about either the underlying causes of these stoichiometric differences, or the consistency of these differences across large geographic extents. 2. Here we analyze elemental (carbon, nitrogen, phosphorus) composition of 872 aquatic macroinvertebrates (71 species) inhabiting tank bromeliads (n = 140) from five distantly located sites across Central and South America to (1) test phylogenetic,...

Data from: Prey diversity, prey composition, and predator population dynamics in experimental microcosms

Owen L. Petchey
1. Food‐web complexity‐stability relations are central to ecology, and many empirical studies show greater food‐web complexity leads to lower population stability. Here, predator population variability decreased with increasing prey diversity in aquatic microcosm experiments, an example of greater food‐web complexity leading to greater population stability. 2. Prey diversity as well as different sets of prey species within each level of prey diversity produced differences in predator population dynamics, demonstrating the importance of both prey composition...

Data from: Differential effect of selection against LINE retrotransposons among vertebrates inferred from whole-genome data and demographic modeling

Alexander T Xue, Robert P. Ruggiero, Michael J. Hickerson & Stéphane Boissinot
Variation in LINE composition is one of the major determinants for the substantial size and structural differences among vertebrate genomes. In particular, the larger genomes of mammals are characterized by hundreds of thousands of copies from a single LINE clade, L1, whereas nonmammalian vertebrates possess a much greater diversity of LINEs, yet with orders of magnitude less in copy number. It has been proposed that such variation in copy number among vertebrates is due to...
