Data from: Fish functional traits correlated with environmental variables in a temperate biodiversity hotspot

Benjamin P. Keck, Zachary H. Marion, Derek J. Martin, Jason C. Kaufman, Carol P. Harden, John S. Schwartz & Richard J. Strange
The global biodiversity crisis has invigorated the search for generalized patterns in most disciplines within the natural sciences. Studies based on organismal functional traits attempt to broaden implications of results by identifying the response of functional traits, instead of taxonomic units, to environmental variables. Determining the functional trait responses enables more direct comparisons with, or predictions for, communities of different taxonomic composition. The North American freshwater fish fauna is both diverse and increasingly imperiled through...

Data from: The impact of shifts in marine biodiversity hotspots on patterns of range evolution: evidence from the Holocentridae (squirrelfishes and soldierfishes)

Alex Dornburg, Jon Moore, Jeremy Michael Beaulieu, Ron I. Eytan & Thomas J. Near
One of the most striking biodiversity patterns is the uneven distribution of marine species richness, with species diversity in the Indo-Australian Archipelago (IAA) exceeding all other areas. However, the IAA formed fairly recently, and marine biodiversity hotspots have shifted across nearly half the globe since the Paleogene. Understanding how lineages have responded to shifting biodiversity hotspots represents a necessary historic perspective on the formation and maintenance of global marine biodiversity. Such evolutionary inferences are often...

Data from: Admixture and the organization of genetic diversity in a butterfly species complex revealed through common and rare genetic variants

Zachariah Gompert, Lauren K. Lucas, C. Alex Buerkle, Matthew L. Forister, James A. Fordyce & Chris C. Nice
Detailed information about the geographic distribution of genetic and genomic variation is necessary to better understand the organization and structure of biological diversity. In particular, spatial isolation within species and hybridization between them can blur species boundaries and create evolutionary relationships that are inconsistent with a strictly bifurcating tree model. Here we analyze genome-wide DNA sequence and genetic ancestry variation in Lycaeides butterflies to quantify the effects of admixture and spatial isolation on how biological...

Data from: Do microorganism stoichiometric alterations affect carbon sequestration in paddy soil subjected to phosphorus input?

Zhi Jian Zhang, Qiang He, ZhiJian Zhang, HongYi Li, Jiao Hu, Xia Li, GuangMing Tian, Hang Wang, ShunYao Wang & Bei Wang
Ecological stoichiometry provides a powerful tool for integrating microbial biomass stoichiometry with ecosystem processes, opening far-reaching possibilities for linking microbial dynamics to soil carbon (C) metabolism in response to agricultural nutrient management. Despite its importance to crop yield, the role of phosphorus (P) with respect to ecological stoichiometry and soil C sequestration in paddy fields remains poorly understood, which limits our ability to predict nutrient-related soil C cycling. Here, we collected soil samples from a...

Data from: Weather-driven dynamics in a dual-migrant system: moths and bats

Jennifer J. Krauel, John K. Westbrook & Gary F. McCracken
Animal migrations generate large spatial and temporal fluctuations in biomass that provide a resource base for many predator-prey interactions. These interactions are often driven by continent-scale weather patterns and are difficult to study. Few studies have included migratory animals on more than a single trophic level or for periods spanning multiple entire seasons. We tracked migrations of three species of agricultural pest noctuid moths over the 2010-2012 autumn seasons as the moths traveled past a...

Data from: Patterns of host plant utilization and diversification in the brush-footed butterflies

Christopher A. Hamm & James A. Fordyce
Herbivorous insects represent one of the most successful animal radiations known. They occupy a wide range of niches, feed on a great variety of plants, and are species rich; yet the factors that influence their diversification are poorly understood. Host breadth is often cited as a major factor influencing diversification, and, according to the Oscillation Hypothesis, shifts from generalist to specialist feeding states increase the diversification rate for a clade. We explored the relationship between...

Data from: Repeated evolution of tricellular (and bicellular) pollen

Joseph H. Williams, Mackenzie L. Taylor & Brian C. O'Meara
Premise of study: Male gametophytes of seed plants are sexually immature at the time they are dispersed as pollen, but approximately 30% of flowering plants have tricellular pollen containing fully formed sperm at anthesis. The classic study of Brewbaker (1967: American Journal of Botany 54: 1069–1083) provided a powerful confirmation of the long-standing hypothesis that tricellular pollen had many parallel and irreversible origins within angiosperms. We readdressed the main questions of that study with modern...

Data from: Evolutionary origins of a bioactive peptide buried within preproalbumin

Alysha G. Elliott, Christina Delay, Huanle Liu, Zaiyang Phua, K. Johan Rosengren, Aurélie H. Benfield, Jose L. Panero, Michelle L. Colgrave, Achala S. Jayasena, Kerry M. Dunse, Marilyn A. Anderson, Edward E. Schilling, Daniel Ortiz-Barrientos, David J. Craik & Joshua S. Mylne
The de novo evolution of proteins is now considered a frequented route for biological innovation, but the genetic and biochemical processes that lead to each newly created protein are often poorly documented. The common sunflower (Helianthus annuus) contains the unusual gene PawS1 (Preproalbumin with SFTI-1) that encodes a precursor for seed storage albumin; however, in a region usually discarded during albumin maturation, its sequence is matured into SFTI-1, a protease-inhibiting cyclic peptide with a motif...

Data from: Nymphalid eyespot serial homologs originate as a few individualized modules

Jeffrey C. Oliver, Jeremy M. Beaulieu, Lawrence F. Gall, William H. Piel & Antónia Monteiro
Serial homologues are repeated traits that share similar development but occur in different parts of the body. Variation in number of repeats accounts for substantial diversity in animal form and considerable work has focused on identifying the factors accounting for this variation. Little is known, however, about how serial homologues originally become repeated, or about the relative timing of repeat individuation relative to repeat origin. Here, we show that the serially repeated eyespots on nymphalid...

Data from: Comparative evaluation of potential indicators and temporal sampling protocols for monitoring genetic erosion

Sean Hoban, Jan A. Arntzen, Michael W. Bruford, José A. Godoy, A. Rus Hoelzel, Gernot Segelbacher, Carles Vilà & Giorgio Bertorelle
Genetic biodiversity contributes to individual fitness, species' evolutionary potential, and ecosystem stability. Temporal monitoring of the genetic status and trends of wild populations' genetic diversity can provide vital data to inform policy decisions and management actions. However, there is a lack of knowledge regarding which genetic metrics, temporal sampling protocols, and genetic markers are sufficiently sensitive and robust, on conservation-relevant timescales. Here, we tested six genetic metrics and various sampling protocols (number and arrangement of...
