Data from: Condition-dependent foraging strategies in a coastal seabird: evidence that the rich get richer

Brock Geary, Scott T. Walter, Paul L. Leberg & Jordan Karubian
The degree to which foraging individuals are able to appropriately modify their behaviors in response to dynamic environmental conditions and associated resource availability can have important fitness consequences. Despite an increasingly refined understanding of differences in foraging behavior between individuals, we still lack detailed characterizations of within-individual variation over space and time, and what factors may drive this variability. From 2014-2017, we used GPS transmitters and accelerometers to document foraging movements by breeding adult Brown...

Data from: Homophily around specialized foraging underlies dolphin social preferences

Alexandre Marcel S. Machado, Maurício Cantor, Ana Paula B. Costa, Barbara P. H. Righetti, Carolina Bezamat, João V. S. Valle-Pereira, Paulo C. Simões-Lopes, Pedro V. Castilho & Fábio G. Daura-Jorge
Individuals often associate socially with those who behave the same way. This principle, homophily, could structure populations into distinct social groups. We tested this hypothesis in a bottlenose dolphin population that appeared to be clustered around a specialized foraging tactic involving cooperation with net-casting fishermen, but in which other potential drivers of such social structure have never been assessed. We measured and controlled for the contribution of sex, age, genetic relatedness, home range, and foraging...

Data from: The emergence of the lobsters: phylogenetic relationships, morphological evolution and divergence time comparisons of an ancient group (Decapoda: Achelata, Astacidea, Glypheidea, Polychelida)

Heather D. Bracken-Grissom, Shane T. Ahyong, Richard D. Wilkinson, Rodney M. Felmann, Carrie E. Schweitzer, Jesse W. Breinholt, Matthew Bendall, Ferran Palero, Tin-Yam Chan, Darryl L. Felder, Rafael Robles, Ka-Hou Chu, Ling-Ming Tsang, Dohyup Kim, Joel W. Martin, Keith A. Crandall & Rodney M. Feldmann
Lobsters are a ubiquitous and economically important group of decapod crustaceans that includes the infraorders Polychelida, Glypheidea, Astacidea and Achelata. They include familiar forms such as the spiny, slipper, clawed lobsters and crayfish and unfamiliar forms such as the deep-sea and “living fossil” species. The high degree of morphological diversity among these infraorders has led to a dynamic classification and conflicting hypotheses of evolutionary relationships. In this study, we estimated phylogenetic relationships amongst the major...

Data from: Seed size evolution and biogeography of Plukenetia (Euphorbiaceae), a pantropical genus with traditionally cultivated oilseed species

Warren M. Cardinal-McTeague, Kenneth J. Wurdack, Erin M. Sigel & Lynn J. Gillespie
Background: Plukenetia is a small pantropical genus of lianas and vines with variably sized edible oil-rich seeds that presents an ideal system to investigate neotropical and pantropical diversification patterns and seed size evolution. We assessed the biogeography and seed evolution of Plukenetia through phylogenetic analyses of a 5,069 character molecular dataset comprising five nuclear and two plastid markers for 86 terminals in subtribe Plukenetiinae (representing 20 of ~23 Plukenetia species). Two nuclear genes, KEA1 and...

Data from: Price equations for understanding the response of ecosystem function to community change

Mark Genung
Biodiversity-ecosystem function research in natural ecosystems would benefit from new theoretical and analytical tools that match common characteristics of observational community data. To this end, we developed a novel, abundance-based version of the ecological Price equation in both discrete and continuous forms. As part of the presentation of this new method, we conducted two demonstration analyses. The first analysis focuses on pollination of watermelon by wild bees. We net-collected wild pollinator specimens from standard areas...

Effects of glaciation and whole genome duplication on the distribution of the Campanula rotundifolia polyploid complex

Brittany Sutherland & Laura F. Galloway
Premise Of The Study Both intrinsic and extrinsic factors contribute to a species distribution. Among plants, the extrinsic effects of glaciation and intrinsic effects of whole genome duplication are powerful drivers of biogeographical patterns, but the interplay of these factors is poorly understood. Here, we investigate the roles glaciation and whole-genome duplication have played in the evolution of the widespread polyploid complex Campanula rotundifolia. Methods We assessed the cytotype of 37 populations that spanned the...

Variation in reproduction and gene flow between cytotypes in a polyploid complex: one size does not fit all

Brittany Sutherland & Laura Galloway
Whole-genome duplication is considered an important speciation mechanism in plants. However, its effect on reproductive isolation between higher cytotypes is not well understood. We used backcrosses between different ploidy levels and surveys of mixed-ploidy contact zones to determine how reproductive barriers differed with cytotype across a polyploid complex. We backcrossed F1 hybrids derived from 2X-4X and 4X-6X crosses in the Campanula rotundifolia autopolyploid complex, measured backcross fitness, and estimated backcross DNA cytotype. We then sampled...

Rare and declining bee species are key to consistent pollination of wildflowers and crops across large spatial scales

Mark Genung, Mark Genung, James Reilly, Neal Williams, Andrew Buderi, Joel Gardner & Rachael Winfree
Biodiversity promotes ecosystem function in experiments, but it remains uncertain how biodiversity loss affects function in larger-scale natural ecosystems, where rare and declining species which are likely to be lost and function needs to be maintained across space and time. Here we explore the importance of rare and declining bee species to the pollination of three wildflowers and three crops using large-scale (72 sites across 5,000 km2), multi-year datasets. Half (82/164) bee species were rare...

Data from: Genetic species delineation among branching Caribbean Porites corals

Carlos Prada, Melissa B. Debiasse, Joseph E. Neigel, Bree Yednock, Joseph L. Stake, Zach H. Foesman, Iliana B. Baums & Michael E. Hellberg
Coral species are difficult to discern because of their morphological plasticity, long generation times, and slow rates of mitochondrial DNA evolution. Amongst Caribbean representatives of the genus Porites are three named species (P. divaricata, P. furcata, and P. porites) with branching colony morphologies whose validity as genetically isolated species has been debated. We present sequence data from the mitochondrial control region, nuclear ITS, and nine single copy nuclear loci for the Caribbean Porites and a...

Data from: Chaotic genetic patchiness without sweepstakes reproduction in the shore crab Hemigrapsus oregonensis

Brendan H. Cornwell, Jennifer L. Fisher, Steven G. Morgan, Joseph E. Neigel, BH Cornwell, JE Neigel, JL Fisher & SG Morgan
Fine-scale spatial and temporal variation in the genetic composition of benthic recruits, known as chaotic genetic patchiness, is often observed in marine and estuarine species with planktonic larvae. Several explanations have been proposed for chaotic genetic patchiness, including sweepstakes reproductive success, variability in larval source and natural selection. In a survey of the green shore crab Hemigrapsus oregonensis in Bodega Bay, California, allele frequencies at a mitochondrial single nucleotide polymorphism were found to differ significantly...

Data from: Phylogenomic analyses support traditional relationships within Cnidaria

Felipe Zapata, Freya E. Goetz, Stephen A. Smith, Mark Howison, Stefan Siebert, Samuel H. Church, Steven M. Sanders, Cheryl Lewis Ames, Catherine S. McFadden, Scott C. France, Marymegan Daly, Allen G. Collins, Steven H. D. Haddock, Casey W. Dunn & Paulyn Cartwright
Cnidaria, the sister group to Bilateria, is the most diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic relationships among major cnidarian lineages are unclear, and recent studies present contrasting phylogenetic hypotheses. Here, we use transcriptome data from 15 newly-sequenced species in combination with 26 publicly available genomes and transcriptomes to assess phylogenetic relationships among major cnidarian lineages. Phylogenetic analyses...

Data from: Use of RAD sequencing for delimiting species

Eric Pante, Jawad Abdelkrim, Amelia Viricel, Delphine Gey, Scott France, Marie-Catherine Boisselier & Sarah Samadi
RAD-tag sequencing is a promising method for conducting genome-wide evolutionary studies. However, to date, only a handful of studies empirically tested its applicability above the species level. In this communication, we use RAD tags to contribute to the delimitation of species within a diverse genus of deep-sea octocorals, Chrysogorgia, for which few classical genetic markers have proved informative. Previous studies have hypothesized that single mitochondrial haplotypes can be used to delimit Chrysogorgia species. On the...

Data from: Birds in space & time: genetic changes accompanying anthropogenic habitat fragmentation in the endangered black-capped vireo (Vireo atricapilla)

Giridhar Athrey, Kelly R. Barr, Richard F. Lance & Paul L. Leberg
Anthropogenic alterations of the natural environment can be a potent evolutionary force. For species that have specific habitat requirements, habitat loss can result in substantial genetic effects, potentially impeding future adaptability and evolution. The endangered black-capped vireo (Vireo atricapilla) suffered a substantial contraction of breeding habitat and population size during much of the 20th century. In a previous study we reported significant differentiation between remnant populations, but failed to recover a strong genetic signal of...
