Data from: Population genetic structure and secondary symbionts in host-associated populations of the pea aphid complex

Julia Ferrari, Joan A West, Sara Via & H. Charles J. Godfray
Polyphagous insect herbivores experience different selection pressures on their various host plant species. How this affects population divergence and speciation may be influenced by the bacterial endosymbionts that many harbor. Here, we study the population structure and symbiont community of the pea aphid (Acyrthosiphon pisum), which feeds on a range of legume species and is known to form genetically differentiated host-adapted populations. Aphids were collected from eight legume genera in England and Germany. Extensive host...

Data from: Parental genetic effects in a cavefish adaptive behavior explain disparity between nuclear and mitochondrial DNA

Masato Yoshizawa, Go Ashida & William R. Jeffery
Epigenetic parental genetic effects are important in many biological processes but their roles in the evolution of adaptive traits and their consequences in naturally evolving populations remain to be addressed. By comparing two divergent blind cave-dwelling cavefish populations with a sighted surface-dwelling population (surface fish) of the teleost Astyanax mexicanus, we report here that convergences in vibration attraction behavior (VAB), the lateral line sensory receptors underlying this behavior, and the feeding benefits of this behavior...

Data from: Trophic niche flexibility in Glossophaga soricina: how a nectar seeker sneaks an insect snack

Elizabeth L. Clare, Holger R. Goerlitz, Violaine A. Drapeau, Marc W. Holderied, Amanda M. Adams, Juliet Nagel, Elizabeth R. Dumont, Paul D. N. Hebert & M. Brock Fenton
Omnivory enables animals to fill more than one trophic niche, providing access to a wider variety of food resources with potentially higher nutrient value, particularly when resources become scarce. Animals can achieve omnivory using different strategies, for example opportunistic foraging, or switching between multiple trophic niches. The Neotropical bat Glossophaga soricina (Pallas, 1766) is a common and widespread species known for nectar-feeding, but it also eats fruit and insects. Approaching stationary objects (flowers and fruits)...

Data from: Food sharing in vampire bats: reciprocal help predicts donations more than relatedness or harassment

Gerald G. Carter & Gerald S. Wilkinson
Common vampire bats often regurgitate food to roost-mates that fail to feed. The original explanation for this costly helping behaviour invoked both direct and indirect fitness benefits. Several authors have since suggested that food sharing is maintained solely by indirect fitness because non-kin food sharing could have resulted from kin recognition errors, indiscriminate altruism within groups, or harassment. To test these alternatives, we examined predictors of food-sharing decisions under controlled conditions of mixed relatedness and...

Data from: \"Genome-wide microsatellite marker development from next-generation sequencing of two non-model bat species impacted by wind turbine mortality: Lasiurus borealis and L. cinereus (Vespertilionidae)\" in Genomic Resources Notes accepted 1 October 2013 to 30 November 2013

Stephen R. Keller, Regina Trott, Cortney Pylant, David N. Nelson & Scott R. Santos
Tree-roosting bats in the genus Lasiurus are widespread, migratory species that have not been well characterized for population genetic diversity and structure due to a lack of genetic resources. Generating genetic resources in Lasiurus is made pressing by the need for conservation genetic assessments of demographic trends in this genus, which comprise a large percentage of bat mortalities at wind turbine sites across North America. We report on marker development from whole-genome Illumina sequencing of...

Data from: Target enrichment of ultraconserved elements from arthropods provides a genomic perspective on relationships among Hymenoptera

Brant C. Faircloth, Michael G. Branstetter, Noor D. White & Séan G. Brady
Gaining a genomic perspective on phylogeny requires the collection of data from many putatively independent loci across the genome. Among insects, an increasingly common approach to collecting this class of data involves transcriptome sequencing, because few insects have high-quality genome sequences available; assembling new genomes remains a limiting factor; the transcribed portion of the genome is a reasonable, reduced subset of the genome to target; and the data collected from transcribed portions of the genome...

Data from: Can RNA-Seq resolve the rapid radiation of advanced moths (Lepidoptera: Apoditrysia)? An exploratory study

Adam L. Bazinet, Michael P. Cummings, Kim T. Mitter & Charles W. Mitter
Recent molecular phylogenetic studies of the insect order Lepidoptera have robustly resolved family-level divergences within most superfamilies, and most divergences among the relatively species-poor early-arising superfamilies. In sharp contrast, relationships among the superfamilies of more advanced moths and butterflies that comprise the mega-diverse clade Apoditrysia (ca. 145,000 spp.) remain mostly poorly supported. This uncertainty, in turn, limits our ability to discern the origins, ages and evolutionary consequences of traits hypothesized to promote the spectacular diversification...

Data from: Differentiating the evolution of female song and male-female duets in the New World blackbirds: can tropical natural history traits explain duet evolution?

Karan J. Odom, Kevin E. Omland & J. Jordan Price
Female bird song and combined vocal duets of mated pairs are both frequently associated with tropical, monogamous, sedentary natural histories. Little is known, however, about what selects for duetting behavior versus female song. Female song likely preceded duet evolution and could drive apparent relationships between duets and these natural histories. We compared the evolution of female song and male-female duets in the New World blackbirds (Icteridae) by investigating patterns of gains and losses of both...

Data from: The incidence and pattern of co-pollinator diversification in dioecious and monoecious figs

Li Yuan Yang, Carlos A. Machado, Xiao-Dong Dang, Yan-Qiong Peng, Da-Rong Yang, Wan-Jin Liao, Da-Yong Zhang & Li-Yuan Yang
Differences in breeding system are associated with correlated ecological and morphological changes in plants. In Ficus, dioecy and monoecy are strongly associated with different suites of traits (tree height, population density, fruiting frequency, pollinator dispersal ecology). Although ~30% of fig species are pollinated by multiple species of fig-pollinating wasps it has been suggested that co-pollinators are rare in dioecious figs. Here we test whether there is a connection between fig breeding system and co-pollinator incidence...

Data from: Neighborhood defense gene similarity effects on tree performance: a community transcriptomic approach

Jenny Zambrano, Yoshiko Iida, Robert Howe, Luxiang Lin, Maria Natalia Umana, Amy Wolf, Samantha J. Worthy & Nathan G. Swenson
The structure and dynamics of ecological communities are ultimately the outcome of the differential demographic rates of individuals. Individual growth and mortality rates largely result from the interaction between an organism's phenotype and the abiotic and biotic environment. Functional traits have been used extensively over the past decade to elucidate links among phenotypes, demography and community dynamics. A fundamental weakness of most functional trait approaches is the use of ‘soft’ traits associated with resource acquisition...

Data from: Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area

Jessica E. Wingfield, Michael O'Brien, Vyacheslav Lyubchich, Jason J. Roberts, Patrick N. Halpin, Aaron N. Rice, Helen Bailey & Michael O’Brien
Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area (WEA) off Maryland, USA, might impact harbour porpoises (Phocoena phocoena), it is essential to determine their poorly understood year-round distribution. Although habitat-based models can help predict the occurrence of species in areas with limited or no sampling, they require validation to determine the accuracy of...

Data from: Combined effects of seed and soil quality drive seedling performance of a late-successional canopy tree in a tropical forest

Jenny Zambrano, Henry F. Howe & Miquel Gonzalez-Meler
Habitat loss and fragmentation affect the structure and functioning of forested ecosystems worldwide, yet we lack an understanding of how species respond to environmental changes. Here, we examined reproductive success and seedling performance of Poulsenia armata (Moraceae) in continuous and fragmented forests of Los Tuxtlas, southern Mexico. We further investigated how maternal habitat and soil conditions manifested in the seedling stage. We determined seed quality and seedling performance by combining isotopic analyses in seed quality...

Data from: Limited pollen dispersal, small genetic neighborhoods, and biparental inbreeding in Vallisneria americana Michx. (Hydrocharitaceae)

Michael Warren Lloyd, Hayley R. Tumas & Maile C. Neel
Premise of the study: Pollen dispersal is a key process that influences ecological and evolutionary dynamics of plant populations by facilitating sexual reproduction and gene flow. Habitat loss and fragmentation have the potential to reduce pollen dispersal within and among habitat patches. We assessed aquatic pollen dispersal and mating system characteristics in Vallisneria americana -- a water-pollinated plant with a distribution that has been reduced from historic levels. Methods: We examined pollen neighborhood size, biparental...

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: An auditory illusion reveals the role of streaming in the temporal misallocation of perceptual objects

Anahita H. Mehta, Nori Jacoby, Ifat Yasin, Andrew J. Oxenham & Shihab A. Shamma
This study investigates the neural correlates and processes underlying the ambiguous percept produced by a stimulus similar to Deutsch's ‘octave illusion’, in which each ear is presented with a sequence of alternating pure tones of low and high frequencies. The same sequence is presented to each ear, but in opposite phase, such that the left and right ears receive a high–low–high … and a low–high–low … pattern, respectively. Listeners generally report hearing the illusion of...

Data from: Prey preference follows phylogeny: evolutionary dietary patterns within the marine gastropod group Cladobranchia (Gastropoda: Heterobranchia: Nudibranchia)

Jessica A. Goodheart, Adam L. Bazinet, Ángel Valdés, Allen G. Collins & Michael P. Cummings
Background: The impact of predator-prey interactions on the evolution of many marine invertebrates is poorly understood. Since barriers to genetic exchange are less obvious in the marine realm than in terrestrial or freshwater systems, non-allopatric divergence may play a fundamental role in the generation of biodiversity. In this context, shifts between major prey types could constitute important factors explaining the biodiversity of marine taxa, particularly in groups with highly specialized diets. However, the scarcity of...

Data from: Quantifying hummingbird preference for floral trait combinations: the role of selection on trait interactions in the evolution of pollination syndromes

Charles B. Fenster, Richard J. Reynolds, Christopher W. Williams, Robert Makowsky & Michele R. Dudash
Darwin recognized the flower's importance for the study of adaptation and emphasized that the flower's functionality reflects the coordinated action of multiple traits. Here we use a multi-trait manipulative approach to quantify the potential role of selection acting on floral trait combinations underlying the divergence and maintenance of three related North American species of Silene (Caryophyllaceae). We artificially generated 48 plant phenotypes corresponding to all combinations of key attractive traits differing among the three Silene...

Data from: How topography induces reproductive asynchrony and alters gypsy moth invasion dynamics

Jonathan A. Walter, Marcia S. Meixler, Thomas Mueller, William F. Fagan, Patrick C. Tobin & Kyle J. Haynes
1. Reproductive asynchrony, a temporal mismatch in reproductive maturation between an individual and potential mates, may contribute to mate-finding failure and Allee effects that influence the establishment and spread of invasive species. Variation in elevation is likely to promote variability in maturation times for species with temperature-dependent development, but it is not known how strongly this influences reproductive asynchrony or the population growth of invasive species. 2. We examined whether spatial variation in reproductive asynchrony,...

Data from: Ecological genomics meets community-level modeling of biodiversity: mapping the genomic landscape of current and future environmental adaptation

Matthew C. Fitzpatrick & Stephen R. Keller
Local adaptation is a central feature of most species occupying spatially heterogeneous environments, and may factor critically in responses to environmental change. However, most efforts to model the response of species to climate change ignore intraspecific variation due to local adaptation. Here, we present a new perspective on spatial modelling of organism–environment relationships that combines genomic data and community-level modelling to develop scenarios regarding the geographic distribution of genomic variation in response to environmental change....

Late Cretaceous domatia reveals the antiquity of plant–mite mutualisms in flowering plants

S. Augusta Maccracken, Ian Miller & Conrad Labandeira
Mite houses, or acarodomatia, are found on the leaves of over 2,000 living species of flowering plants today. These structures facilitate tri-trophic interactions between the host plant, its fungi or herbivore adversaries, and fungivorous or predaceous mites by providing shelter for the consumers. Previously, the oldest acarodomatia were described on a Cenozoic Era fossil leaf dating to 49 million years in age. Here, we report the first occurrence of Mesozoic Era acarodomatia in the fossil...

Data from: Polyandry and polygyny in a social rodent: an integrative perspective based on social organization, copulations, and genetics

John L. Hoogland, Regina Trott & Stephen R. Keller
Animal mating systems have fascinated biologists for thousands of years. Ways to describe amating systeminclude determining social organization, observing copulations, or using genetics to assign parentage. Social organization can be difficult to quantify, however, documentation of copulations is often challenging, many copulations do not produce offspring, and genetic variation is sometimes minimal. Here we use data from a 7-year study of wild white-tailed prairie dogs (WTPDs, Cynomys leucurus) living in Colorado USA to estimate the...

Data from: Challenges in the conservation of wide-ranging nomadic species

Dejid Nandintsetseg, Chloe Bracis, Kirk A. Olson, Katrin Böhning-Gaese, Justin M. Calabrese, Buyanaa Chimeddorj, William F. Fagan, Christen H. Fleming, Michael Heiner, Petra Kaczensky, Peter Leimgruber, Dalannast Munkhnast, Theresa Stratmann & Thomas Mueller
1. Conservation of nomadic ungulates presents significant conservation challenges because of unpredictability in their movements and space use. Long-term studies on nomadic ungulates offering insights into the variability in space use within and between years are largely missing but are necessary to develop effective conservation strategies. 2. We examined the temporal variability in space-use of 22 Mongolian gazelle, tracked for one to three years with GPS and used the resulting movement patterns to evaluate conservation...

Data from: A comprehensive analysis of autocorrelation and bias in home range estimation

Michael J. Noonan, Marlee A. Tucker, Christen H. Fleming, Tom S. Akre, Susan C. Alberts, Abdullahi H. Ali, Jeanne Altmann, Pamela C. Antunes, Jerrold L. Belant, Dean Beyer, Niels Blaum, Katrin Böhning-Gaese, , Rogerio De Paula Cunha, Jasja Dekker, Jonathan Drescher-Lehman, Nina Farwig, Claudia Fichtel, Christina Fischer, Adam T. Ford, Jacob R. Goheen, René Janssen, Florian Jeltsch, Matthew Kauffman, Peter M. Kappeler … & Justin M. Calabrese
Home range estimation is routine practice in ecological research. While advances in animal tracking technology have increased our capacity to collect data to support home range analysis, these same advances have also resulted in increasingly autocorrelated data. Consequently, the question of which home range estimator to use on modern, highly autocorrelated tracking data remains open. This question is particularly relevant given that most estimators assume independently sampled data. Here, we provide a comprehensive evaluation of...
