Owen A. Thompson, L. Basten Snoek, Harm Nijveen, Mark G. Sterken, Rita J. M. Volkers, Rachel Brenchley, Arjen Van't Hof, Roel P. J. Bevers, Andrew R. Cossins, Itai Yanai, Alex Hajnal, Tobias Schmid, Jaryn D. Perkins, David Spencer, Leonid Kruglyak, Erik C. Andersen, Donald G. Moerman, LaDeana W. Hillier, Jan E. Kammenga & Robert H. Waterston
The Hawaiian strain (CB4856) of Caenorhabditis elegans is one of the most divergent from the canonical laboratory strain N2 and has been widely used in developmental, population and evolutionary studies. To enhance the utility of the strain, we have generated a draft sequence of the CB4856 genome, exploiting a variety of resources and strategies. The CB4856 genome when compared against the N2 reference has 327,050 single nucleotide variants (SNVs) and 79,529 insertion-deletion events (indels) that...

Data from: Evolution and maintenance of haploid-diploid life cycles in natural populations: the case of the marine brown alga Ectocarpus

Lucía Couceiro, Mickael Le Gac, Heather M. Hunsperger, Stéphane Mauger, Christophe Destombe, J. Mark Cock, Sophia Ahmed, Susana M. Coelho, Myriam Valero & Akira F. Peters
The evolutionary stability of haploid-diploid life cycles is still controversial. Mathematical models indicate that niche differences between ploidy phases may be a necessary condition for the evolution and maintenance of these life cycles. Nevertheless, experimental support for this prediction remains elusive. In the present work, we explored this hypothesis in natural populations of the brown alga Ectocarpus. Consistent with the life cycle described in culture, E. crouaniorum in NW France and E. siliculosus in SW...

Data from: Age specific survival rates of Steller sea lions at rookeries with divergent population trends in the Russian Far East

Alexey V. Altukhov, Russel D. Andrews, Donald G. Calkins, Thomas S. Gelatt, Eliezer D. Gurarie, Thomas R. Loughlin, Evgeny G. Mamaev, Victor S. Nikulin, Peter A. Permyakov, Sergey D. Ryazanov, Vladimir V. Vertyankin & Vladimir N. Burkanov
After a dramatic population decline, Steller sea lions have begun to recover throughout most of their range. However, Steller sea lions in the Western Aleutians and Commander Islands are continuing to decline. Comparing survival rates between regions with different population trends may provide insights into the factors driving the dynamics, but published data on vital rates have been extremely scarce, especially in regions where the populations are still declining. Fortunately, an unprecedented dataset of marked...

Data from: Community-wide changes in inter-taxonomic temporal co-occurrence resulting from phenological shifts

Fangyuan Hua, Junhua Hu, Yang Liu, Xingli Giam, Tien Ming Lee, Hao Luo, Jia Wu, Qiaoyi Liang, Jian Zhao, Xiaoyan Long, Hong Pang, Biao Wang, Wei Liang, Zhengwang Zhang, Xuejie Gao & Jiang Zhu
Global climate change is known to affect the assembly of ecological communities by altering species’ spatial distribution patterns, but little is known about how climate change may affect community assembly by changing species’ temporal co-occurrence patterns, which is highly likely given the widely observed phenological shifts associated with climate change. Here we analyzed a 29-year phenological data set comprising community-level information on the timing and span of temporal occurrence in 11 seasonally occurring animal taxon...

Data from: Short tree, long tree, right tree, wrong tree: new acquisition bias corrections for inferring SNP phylogenies

Adam D. Leaché, Barbara L. Banbury, Joseph Felsenstein, Adrián Nieto-Montes De Oca & Alexandros Stamatakis
Single nucleotide polymorphisms (SNPs) are useful markers for phylogenetic studies owing in part to their ubiquity throughout the genome and ease of collection. Restriction site associated DNA sequencing (RADseq) methods are becoming increasingly popular for SNP data collection, but an assessment of the best practises for using these data in phylogenetics is lacking. We use computer simulations, and new double digest RADseq (ddRADseq) data for the lizard family Phrynosomatidae, to investigate the accuracy of RAD...

Data from: Injuries, death, and disability associated with 11 years of conflict in Baghdad, Iraq: a randomized household cluster survey

Riyadh Lafta, Sahar Al-Shatari, Megan Cherewick, Lindsay Galway, Charles Mock, Amy Hagopian, Abraham Flaxman, Tim Takaro, Anna Greer, Adam Kusner & Gilbert Burnham
Background: The objective of this study was to characterize injuries, deaths, and disabilities arising during 11 years of conflict in Baghdad. Methods: Using satellite imagery and administrative population estimated size for Baghdad, 30 clusters were selected, proportionate to population size estimates. Interviews were conducted during April and May 2014 in 900 households containing 5148 persons. Details about injuries and disabilities occurring from 2003 through May 2014 and resultant disabilities were recorded. Findings: There were 553...

Data from: New evidence for hybrid zones of forest and savanna elephants in Central and West Africa

Samrat Mondol, Ida Moltke, John Hart, Michael Keigwin, Lisa Brown, Matthew Stephens & Samuel K. Wasser
The African elephant consists of forest and savanna subspecies. Both subspecies are highly endangered due to severe poaching and habitat loss, and knowledge of their population structure is vital to their conservation. Previous studies have demonstrated marked genetic and morphological differences between forest and savanna elephants and despite extensive sampling, genetic evidence of hybridization between them has been restricted largely to a few hybrids in the Garamba region of northeastern Democratic Republic of Congo (DRC)....

Data from: Integration of Random Forest with population-based outlier analyses provides insight on the genomic basis and evolution of run timing in Chinook salmon (Oncorhynchus tshawytscha)

Marine S. O. Brieuc, Kotaro Ono, Daniel P. Drinan & Kerry A. Naish
Anadromous Chinook salmon populations vary in the period of river entry at the initiation of adult freshwater migration, facilitating optimal arrival at natal spawning. Run timing is a polygenic trait that shows evidence of rapid parallel evolution in some lineages, signifying a key role for this phenotype in the ecological divergence between populations. Studying the genetic basis of local adaptation in quantitative traits is often impractical in wild populations. Therefore, we used a novel approach,...

Data from: Biotic and climatic velocity identify contrasting areas of vulnerability to climate change

Carlos Carroll, Joshua J. Lawler, David R. Roberts & Andreas Hamann
Metrics that synthesize the complex effects of climate change are essential tools for mapping future threats to biodiversity and predicting which species are likely to adapt in place to new climatic conditions, disperse and establish in areas with newly suitable climate, or face the prospect of extirpation. The most commonly used of such metrics is the velocity of climate change, which estimates the speed at which species must migrate over the earth’s surface to maintain...

Data from: Climate oscillations, glacial refugia, and dispersal ability: factors influencing the genetic structure of the least salmonfly, Pteronarcella badia (Plecoptera), in Western North America

John S. Sproul, Derek D. Houston, C. Riley Nelson, R. Paul Evans, Keith A. Crandall & Dennis K. Shiozawa
Background: Phylogeographic studies of aquatic insects provide valuable insights into mechanisms that shape the genetic structure of communities, yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America. We tested hypotheses related to mode of dispersal and the influence of historic climate oscillations on population genetic structure. In order to generate a larger mitochondrial data...

Data from: Assessing vertebrate biodiversity in a kelp forest ecosystem using environmental DNA

Jesse A. Port, James L. O'Donnell, Ofelia C. Romero-Maraccini, Paul R. Leary, Steven Y. Litvin, Kerry J. Nickols, Kevan M. Yamahara & Ryan P. Kelly
Preserving biodiversity is a global challenge requiring data on species’ distribution and abundance over large geographic and temporal scales. However, traditional methods to survey mobile species’ distribution and abundance in marine environments are often inefficient, environmentally destructive, or resource-intensive. Metabarcoding of environmental DNA (eDNA) offers a new means to assess biodiversity and on much larger scales, but adoption of this approach for surveying whole animal communities in large, dynamic aquatic systems has been slowed by...

Data from: The influence of adult attachment on patient self-management in primary care

Katja Brenk-Franz, Bernhard Strauß, Fabian Tiesler, Christian Fleischhauer, Paul Ciechanowski, Nico Schneider & Jochen Gensichen
Objective: Self-management strategies are essential elements of evidence-based treatment in patients with chronic conditions in primary care. Our objective was to analyse different self-management skills and behaviours and their association to adult attachment in primary care patients with multiple chronic conditions. Methods: In the apricare study (Adult Attachment in Primary Care) we used a prospective longitudinal design to examine the association between adult attachment and self-management in primary care patients with multimorbidity. The attachment dimensions...

Data from: Phylogenomics of horned lizards (genus: Phrynosoma) using targeted sequence capture data

Adam D. Leaché & Charles W. Linkem
New genome sequencing techniques are enabling phylogenetic studies to scale-up from using a handful of loci to hundreds or thousands of loci from throughout the genome. In this study, we use targeted sequence capture (TSC) data from 540 ultraconserved elements and 44 protein-coding genes to estimate the phylogenetic relationships among all 17 species of horned lizards in the genus Phrynosoma. Previous molecular phylogenetic analyses of Phrynosoma based on a few nuclear genes, restriction site associated...

Data from: Keeping cool: enhanced optical reflection and heat dissipation in silver ants

Norman Nan Shi, Cheng-Chia Tsai, Fernando Camino, Gary D. Bernard, Nanfang Yu & Rüdiger Wehner
Saharan silver ants, Cataglyphis bombycina, forage under extreme temperature conditions in the African desert. We show that the ants’ conspicuous silvery appearance is created by a dense array of triangular hairs with two thermoregulatory effects. They enhance not only the reflectivity of the ant’s body surface in the visible and near-infrared range of the spectrum, where solar radiation culminates, but also the emissivity of the ant in the mid-infrared. The latter effect enables the animals...

Data from: Effectiveness of managed gene flow in reducing genetic divergence associated with captive breeding

Charles D. Waters, Jeffrey J. Hard, Marine S. O. Brieuc, David E. Fast, Kenneth I. Warheit, Robin Waples, Curtis M. Knudsen, William J. Bosch, Kerry A. Naish & Robin S. Waples
Captive breeding has the potential to rebuild depressed populations. However, associated genetic changes may decrease restoration success and negatively affect the adaptive potential of the entire population. Thus, approaches that minimize genetic risks should be tested in a comparative framework over multiple generations. Genetic diversity in two captive-reared lines of a species of conservation interest, Chinook salmon (Oncorhynchus tshawytscha), was surveyed across three generations using genome-wide approaches. Genetic divergence from the source population was minimal...

Data from: Temporal genetic variance and propagule-driven genetic structure characterize naturalized rainbow trout (Oncorhynchus mykiss) from a Patagonian lake impacted by trout farming

Javiera Nidia Benavente, Lisa Wishard Seeb, James Edward Seeb, Ivan Arismendi, Cristián Esteban Hernández, Gonzalo Gajardo, Ricardo Galleguillos, Maria Ignacia Cádiz, Selim Seman Musleh & Daniel Gomez-Uchida
Knowledge about the genetic underpinnings of invasions—a theme addressed by invasion genetics as a discipline—is still scarce amid well documented ecological impacts of non-native species on ecosystems of Patagonia in South America. One of the most invasive species in Patagonia’s freshwater systems and elsewhere is rainbow trout (Oncorhynchus mykiss). The species was introduced in Chile during the early twentieth century for stocking and promoting recreational fishing and, during the late twentieth century, for farming purposes...

Data from: Molecular phylogeny of the subfamily Stevardiinae Gill, 1858 (Characiformes: Characidae): classification and the evolution of reproductive traits

Andréa T. Thomaz, Dahiana Arcila, Guillermo Ortí & Luiz R. Malabarba
Background The subfamily Stevardiinae is a diverse and widely distributed clade of freshwater fishes from South and Central America, commonly known as “tetras” (Characidae). The group was named “clade A” when first proposed as a monophyletic unit of Characidae and later designated as a subfamily. Stevardiinae includes 48 genera and around 310 valid species with many species presenting inseminating reproductive strategy. No global hypothesis of relationships is available for this group and currently many genera...

Data from: Sizing ocean giants: patterns of intraspecific size variation in marine megafauna

Craig R. McClain, Meghan A. Balk, Mark C. Benfield, Trevor A. Branch, Catherine Chen, James Cosgrove, Alistair D. M. Dove, Leo C. Gaskins, Rebecca Helm, Frederick G. Hochberg, Frank B. Lee, Andrea Marshall, Steven E. McMurray, Caroline Schanche, Shane N. Stone, Andrew D. Thaler & Rebecca R. Helm
What are the greatest sizes that the largest marine megafauna obtain? This is a simple question with a difficult and complex answer. Many of the largest-sized species occur in the world’s oceans. For many of these, rarity, remoteness, and quite simply the logistics of measuring these giants has made obtaining accurate size measurements difficult. Inaccurate reports of maximum sizes run rampant through the scientific literature and popular media. Moreover, how intraspecific variation in the body...

Data from: Phylogenomics of phrynosomatid lizards: conflicting signals from sequence capture versus restriction site associated DNA sequencing

Adam D. Leaché, Andreas S. Chavez, Leonard N. Jones, Jared A. Grummer, Andrew D. Gottscho & Charles W. Linkem
Sequence capture and restriction site associated DNA sequencing (RADseq) are popular methods for obtaining large numbers of loci for phylogenetic analysis. These methods are typically used to collect data at different evolutionary timescales; sequence capture is primarily used for obtaining conserved loci, whereas RADseq is designed for discovering single nucleotide polymorphisms (SNPs) suitable for population genetic or phylogeographic analyses. Phylogenetic questions that span both “recent” and “deep” timescales could benefit from either type of data,...

Data from: Deconstructing Darwin’s naturalization conundrum in the San Juan Islands using community phylogenetics and functional traits

Hannah E. Marx, David E. Giblin, Peter W. Dunwiddie & David C. Tank
Aim: Darwin posed a conundrum about species invasions, postulating the importance of functional distinctiveness from the receiving native community to avoid competition, and, at the same time, the importance of shared similarity to pass environmental filters and successfully establish. Using phylogenetic distances and functional traits, we assessed this conundrum in the flora of 80 mostly uninhabited islands, where over 30% of the species are invasive. We highlight the importance of publicly available datasets to disentangle...

Data from: The impacts of Wolbachia and the microbiome on mate choice in Drosophila melanogaster

Devin Arbuthnott, Tera C. Levin & Daniel E. L. Promislow
Symbionts and parasites can manipulate their hosts’ reproduction to their own benefit, profoundly influencing patterns of mate choice and evolution of the host population. Wolbachia is one of the most widespread symbionts among arthropods, and one that alters its hosts’ reproduction in diverse and dramatic ways. While we are beginning to appreciate how Wolbachia's extreme manipulations of host reproduction can influence species diversification and reproductive isolation, we understand little about how symbionts and Wolbachia, in...

Data from: Dual dimensionality reduction reveals independent encoding of motor features in a muscle synergy for insect flight control

Simon N. Sponberg, Thomas L. Daniel, Adrienne L. Fairhall & Simon Sponberg
What are the features of movement encoded by changing motor commands? Do motor commands encode movement independently or can they be represented in a reduced set of signals (i.e. synergies)? Motor encoding poses a computational and practical challenge because many muscles typically drive movement, and simultaneous electrophysiology recordings of all motor commands are typically not available. Moreover, during a single locomotor period (a stride or wingstroke) the variation in movement may have high dimensionality, even...

Data from: Genome-wide association studies in dogs and humans identify ADAMTS20 as a risk variant for cleft lip and palate

Zena T. Wolf, Harrison A. Brand, John R. Shaffer, Elizabeth J. Leslie, Boaz Arzi, Cali E. Willet, Timothy C. Cox, Toby McHenry, Nicole Narayan, Eleanor Feingold, Xioajing Wang, Saundra Sliskovic, Nili Karmi, Noa Safra, Carla Sanchez, Frederic W. B. Deleyiannis, Jeffrey C. Murray, Claire M. Wade, Mary L. Marazita & Danika L. Bannasch
Cleft lip with or without cleft palate (CL/P) is the most commonly occurring craniofacial birth defect. We provide insight into the genetic etiology of this birth defect by performing genome-wide association studies in two species: dogs and humans. In the dog, a genome-wide association study of 7 CL/P cases and 112 controls from the Nova Scotia Duck Tolling Retriever (NSDTR) breed identified a significantly associated region on canine chromosome 27 (unadjusted p=1.1 x 10-13; adjusted...

Data from: Performance of Encounternet tags: field tests of miniaturized proximity loggers for use on small animals

Iris I. Levin, David M. Zonana, John M. Burt & Rebecca J. Safran
Proximity logging is a new tool for understanding social behavior as it allows for accurate quantification of social networks. We report results from field calibration and deployment tests of miniaturized proximity tags (Encounternet), digital transceivers that log encounters between tagged individuals. We examined radio signal behavior in relation to tag attachment (tag, tag on bird, tag on saline-filled balloon) to understand how radio signal strength is affected by the tag mounting technique used for calibration...

Data from: Playing 20 Questions with the mind: collaborative problem solving by humans using a brain-to-brain interface

Andrea Stocco, Chantel S. Prat, Darby M. Losey, Jeneva A. Cronin, Joseph Wu, Justin A. Abernethy & Rajesh P. N. Rao
We present, to our knowledge, the first demonstration that a non-invasive brain-to-brain interface (BBI) can be used to allow one human to guess what is on the mind of another human through an interactive question-and-answering paradigm similar to the “20 Questions” game. As in previous non-invasive BBI studies in humans, our interface uses electroencephalography (EEG) to detect specific patterns of brain activity from one participant (the “respondent”), and transcranial magnetic stimulation (TMS) to deliver functionally-relevant...
