Data from: The effects of nutrient enrichment and invasive mollusks on freshwater environments

Matthew Schuler, William Hintz, Devin Jones, Brian Mattes, Aaron Stoler & Rick Relyea
The effects of invasive species might be altered by anthropogenic activities such as nutrient pollution or the presence of additional invasive species with similar or unique traits. Using experimental mesocosms, we tested the separate and combined effects of three invasive mollusks (zebra mussels, Asian clams, and banded mystery snails) on freshwater environments in nutrient-poor and nutrient-enriched conditions. We predicted that in nutrient-poor conditions, single mollusk species would reduce the abundance of algae and zooplankton, but...

Data from: Comparative analyses of effective population size within and among species: ranid frogs as a case study

Ivan C Phillipsen, W. Chris Funk, Eric A. Hoffman, Kirsten J. Monsen & Michael S. Blouin
It has recently become practicable to estimate the effective sizes (Ne) of multiple populations within species. Such efforts are valuable for estimating Ne in evolutionary modeling and conservation planning. We used microsatellite loci to estimate Ne of 90 populations of four ranid frogs (20 to 26 populations per species, mean n per population = 29). Our objectives were to determine typical values of Ne for populations of each species, compare Ne estimates among the species,...

Data from: Carrion fly-derived DNA metabarcoding is an effective tool for mammal surveys: evidence from a known tropical mammal community

Torrey W. Rodgers, Charles C. Y. Xu, Jacalyn Giacalone, Karen M. Kapheim, Kristin Saltonstall, Marta Vargas, Douglas W. Yu, Panu Somervuo, W. Owen McMillan & Patrick A. Jansen
Metabarcoding of vertebrate DNA derived from carrion flies has been proposed as a promising tool for biodiversity monitoring. To evaluate its efficacy, we conducted metabarcoding surveys of carrion flies on Barro Colorado Island (BCI), Panama, which has a well-known mammal community, and compared our results against diurnal transect counts and camera-trapping. We collected 1084 flies in 29 sampling days, conducted metabarcoding with mammal-specific (16S) and vertebrate-specific (12S) primers, and sequenced amplicons on Illumina MiSeq. For...

Data from: Convergent evolution of alternative developmental trajectories associated with diapause in African and South American killifish

Andrew I. Furness, David N. Reznick, Mark S. Springer & Robert W. Meredith
Annual killifish adapted to life in seasonally ephemeral water-bodies exhibit desiccation resistant eggs that can undergo diapause, a period of developmental arrest, enabling them to traverse the otherwise inhospitable dry season. Environmental cues that potentially indicate the season can govern whether eggs enter a stage of diapause mid-way through development or skip this diapause and instead undergo direct development. We report, based on construction of a supermatrix phylogenetic tree of the order Cyprinodontiformes and a...

Data from: Diet assessment of the Atlantic Sea Nettle Chrysaora quinquecirrha in Barnegat Bay, New Jersey, using next-generation sequencing

Robert W. Meredith, John J. Gaynor, Paul A.X. Bologna & Paul A. X. Bologna
Next generation sequencing (NGS) methodologies have proven useful in deciphering the food items of generalist predators, but have yet to be applied to gelatinous animal gut and tentacle content. NGS can potentially supplement traditional methods of visual identification. Chrysaora quinquecirrha (Atlantic sea nettle) has progressively become more abundant in Mid-Atlantic United States’ estuaries including Barnegat Bay (New Jersey), potentially having detrimental effects on both marine organisms and human enterprises. Full characterization of this predator's diet...

Data from: Molecular phylogeny and SNP variation of polar bears (Ursus maritimus), brown bears (U. arctos) and black bears (U. americanus) derived from genome sequences

Matthew A. Cronin, Gonzalo Rincon, Robert W. Meredith, Michael D. MacNeil, Alma Islas-Trejo, Angela Canovas & Juan F. Medrano
We assessed the relationships of polar bears (Ursus maritimus), brown bears (U. arctos), and black bears (U. americanus) with high throughput genomic sequencing data with an average coverage of 25X for each species. A total of 1.4 billion 100-bp paired-end reads was assembled using the polar bear and annotated giant panda (Ailuropoda melanoleuca) genome sequences as references. We identified 13.8 million single nucleotide polymorphisms (SNP) in the three species aligned to the polar bear genome....

Data from: Genomic signatures of spatially divergent selection at clownfish range margins

Rene Clark, Matthew Aardema, Peter Andolfatto, Paul Barber, Akihisa Hattori, Jennifer Hoey, & Malin Pinsky
Understanding how evolutionary forces interact to drive patterns of selection and distribute genetic variation across a species’ range is of great interest in ecology and evolution, especially in an era of global change. While theory predicts how and when populations at range margins are likely to undergo local adaptation, empirical evidence testing these models remains sparse. Here, we address this knowledge gap by investigating the relationship between selection, gene flow, and genetic drift in the...
