Towards scaling laws for DDT in obstructed channels

Elaine S. Oran & Vadim N. Gamezo
In a coal mine, natural gas can leak through walls and accumulate in enclosed regions that are no longer being mined or ventilated. If there is an accidental spark in the region containing this gas, it can ignite a flame that may transition to detonation (DDT). An important problem is to assess if, when, and where DDT can occur, and thus provide information needed to design strong enough barriers to protect active mining areas. We...

Data from: Genetic data reveal mixed-stock aggregations of gray whales in the North Pacific Ocean

Anna Brüniche-Olsen, R. Jorge Urban, Vladimir V. Vertyankin, Celine A.J. Godard-Codding, John W. Bickham & J. Andrew DeWoody
Gray whales (Eschrichtius robustus) in the Western Pacific are critically endangered whereas in the Eastern Pacific they are relatively common. Holocene environmental changes and commercial whaling reduced their numbers, but gray whales in the Eastern Pacific now outnumber their Western counterparts by more than 100-fold. Herein, we investigate the genetic diversity and population structure within the species using a panel of genic SNPs. Results indicate the gray whale gene pool is differentiated into two substocks...

Data from: Independent origins of resistance or susceptibility of parasitic wasps to a defensive symbiont

Mariana Mateos, Lauryn Winter, Caitlyn Winter, Victor M. Higareda-Alvear, Esperanza Martinez-Romero & Jialei Xie
Insect microbe associations are diverse, widespread, and influential. Among the fitness effects of microbes on their hosts, defense against natural enemies is increasingly recognized as ubiquitous, particularly among those associations involving heritable, yet facultative, bacteria. Protective mutualisms generate complex ecological and co-evolutionary dynamics that are only beginning to be elucidated. These depend in part on the degree to which symbiont-mediated protection exhibits specificity to one or more members of the natural enemy community. Recent findings...

Data from: Reliability and construct validity of the Psychopathic Personality Inventory-Revised in a Swedish non-criminal sample: a multimethod approach including psychophysiological correlates of empathy for pain

Karolina Sörman, Gustav Nilsonne, Katarina Howner, Sandra Tamm, Shilan Caman, Hui-Xin Wang, Martin Ingvar, John F. Edens, Petter Gustavsson, Scott O. Lilienfeld, Predrag Petrovic, Håkan Fischer & Marianne Kristiansson
Cross-cultural investigation of psychopathy measures is important for clarifying the nomological network surrounding the psychopathy construct. The Psychopathic Personality Inventory-Revised (PPI-R) is one of the most extensively researched self-report measures of psychopathic traits in adults. To date however, it has been examined primarily in North American criminal or student samples. To address this gap in the literature, we examined PPI-R’s reliability, construct validity and factor structure in non-criminal individuals (N = 227) in Sweden, using...

Data from: Populations at risk: conservation genetics of kangaroo mice (Microdipodops) of the Great Basin Desert

John J. Andersen, David S. Portnoy, John C. Hafner & Jessica E. Light
The Great Basin Desert of western North America has experienced frequent habitat alterations due to a complex biogeographic history and recent anthropogenic impacts, with the more recent alterations likely resulting in the decline of native fauna and flora. Dark (Microdipodops megacephalus) and pallid (M. pallidus) kangaroo mice are ecological specialists found within the Great Basin Desert and are potentially ideal organisms for assessing ecosystem health and inferring the biogeographic history of this vulnerable region. Herein,...

Data from: Multi-locus sequence data reveal a new species of coral reef goby (Teleostei: Gobiidae: Eviota), and evidence of Pliocene vicariance across the Coral Triangle

Luke Tornabene, Samantha Valdez, Mark V. Erdmann & Frank L. Pezold
Here, multi-locus sequence data are coupled with observations of live colouration to recognize a new species, Eviota punyit from the Coral Triangle, Indian Ocean and Red Sea. Relaxed molecular clock divergence time estimation indicates a Pliocene origin for the new species, and the current distribution of the new species and its sister species Eviota sebreei supports a scenario of vicariance across the Indo-Pacific Barrier, followed by subsequent range expansion and overlap in the Coral Triangle....

Data from: A tale of two studies: detection and attribution of the impacts of invasive plants in observational surveys

Kevin E. Mueller, Alexandra G. Lodge, Alexander M. Roth, Timothy J. S. Whitfeld, Sarah E. Hobbie & Peter B. Reich
1.Short-term experiments cannot characterize how long-lived, invasive shrubs influence ecological properties that can be slow to change, including native diversity and soil fertility. Observational studies are thus necessary, but often suffer from methodological issues. 2.To highlight ways of improving the design and interpretation of observational studies that assess the impacts of invasive plants, we compare two studies of nutrient cycling and earthworms along two separate gradients of invasive shrub abundance. By considering the divergent sampling...

Data from: Common bottlenose dolphin (Tursiops truncatus) behavior in an active narrow seaport

Sarah Piwetz
The Galveston Ship Channel (GSC) is a narrow, congested waterway that supports large-scale shipping, commercial fishing, dolphin tourism, and recreation. Human activity and common bottlenose dolphins (Tursiops truncatus) converge in the GSC with potentially negative consequences on the dolphins. Elevated land-based tracking and behavioral observation of dolphins and vessels were conducted along the GSC in June-August 2013 using a digital theodolite. Positional information was used to calculate dolphin movement patterns and proximity to vessels. Log-likelihood...

Data from: High-resolution mapping reveals hundreds of genetic incompatibilities in hybridizing fish species

Molly Schumer, Rongfeng Cui, Daniel Powell, Rebecca Dresner, Gil G. Rosenthal, Peter Andolfatto & Daniel L Powell
Hybridization is increasingly being recognized as a common process in both animal and plant species. Negative epistatic interactions between genes with different parental ancestry decrease the fitness of hybrids and can limit gene flow between species. However, little is known about the number and genome-wide distribution of genetic incompatibilities separating species. To detect interacting genes, we perform a detailed genome scan for linkage disequilibrium between unlinked genomic regions in naturally occurring hybrid populations of swordtail...

Data from: Multicopy single-stranded DNA directs intestinal colonization of enteric pathogens

Johanna R. Elfenbein, Leigh A. Knodler, Ernesto S. Nakayasu, Charles Ansong, Heather M. Brewer, Lydia Bogomolnaya, L. Garry Adams, Michael McClelland, Joshua N. Adkins & Helene L. Andrews-Polymenis
Multicopy single-stranded DNAs (msDNAs) are hybrid RNA-DNA molecules encoded on retroelements called retrons and produced by the action of retron reverse transcriptases. Retrons are widespread in bacteria but the natural function of msDNA has remained elusive despite 30 years of study. The major roadblock to elucidation of the function of these unique molecules has been the lack of any identifiable phenotypes for mutants unable to make msDNA. We report that msDNA of the zoonotic pathogen...

Data from: Effective population size of malaria mosquitoes: large impact of vector control

Giridhar Athrey, Theresa K. Hodges, Michael R. Reddy, Hans J. Overgaard, Abrahan Matias, Frances C. Ridl, Immo Kleinschmidt, Adalgisa Caccone & Michel A. Slotman
Malaria vectors in sub-Saharan Africa have proven themselves very difficult adversaries in the global struggle against malaria. Decades of anti-vector interventions have yielded mixed results – with successful reductions in transmission in some areas, and limited impacts in others. These varying successes can be ascribed to a lack of universally effective vector control tools, as well as the development of insecticide resistance in mosquito populations. Understanding the impact of vector control on mosquito populations is...

Bagavathiannan, James Henrichson, Ezekiel Bowden, John Valasek, Jeff Olsenholler, Michael P. Bishop, Ryan Sheridan, Eric B. Putman, Sorin Popescu, Travis Burks, Dale Cope, Amir Ibrahim, Billy F. McCutchen, David D. Baltensperger … & James Henrickson
Advances in automation and data science have led agriculturists to seek real-time, high-quality, high-volume crop data to accelerate crop improvement through breeding and to optimize agronomic practices. Breeders have recently gained massive data-collection capability in genome sequencing of plants. Faster phenotypic trait data collection and analysis relative to genetic data leads to faster and better selections in crop improvement. Furthermore, faster and higher-resolution crop data collection leads to greater capability for scientists and growers to...

Data from: A method for detecting recent changes in contemporary effective population size from linkage disequilibrium at linked and unlinked loci

Christopher M. Hollenbeck, David S. Portnoy & John R. Gold
Estimation of contemporary effective population size (Ne) from linkage disequilibrium (LD) between unlinked pairs of genetic markers has become an important tool in the field of population and conservation genetics. If data pertaining to physical linkage or genomic position are available for genetic markers, estimates of recombination rate between loci can be combined with LD data to estimate contemporary Ne at various times in the past. We extend the well-known, LD-based method of estimating contemporary...

Data from: Population genomics reveals multiple drivers of population differentiation in a sex-role-reversed pipefish

Sarah P. Flanagan, Emily Rose & Adam G. Jones
A major goal of molecular ecology is to identify the causes of genetic and phenotypic differentiation among populations. Population genomics is suitably poised to tackle these key questions by diagnosing the evolutionary mechanisms driving divergence in nature. Here, we set out to investigate the evolutionary processes underlying population differentiation in the Gulf pipefish, Syngnathus scovelli. We sampled approximately 50 fish from each of 12 populations distributed from the Gulf coast of Texas to the Atlantic...

Data from: Does the niche-breadth or trade-off hypothesis explain the abundance-occupancy relationship in avian haemosporidia?

Sergei V. Drovetski, Sargis A. Aghayan, Vanessa A. Mata, Ricardo J. Lopes, Nicolle A. Mode, Johanna A. Harvey & Gary Voelker
Two hypotheses have been proposed to explain the abundance-occupancy relationship (AOR) in parasites. The niche-breadth hypothesis suggests that host generalists are more abundant and efficient at colonizing different host communities than specialists. The trade-off hypothesis argues that host specialists achieve high density across their hosts’ ranges, whereas generalists incur the high cost of adaptation to diverse immuno-defense systems. We tested these hypotheses using 386 haemosporidian cytochrome-b lineages (1894 sequences) recovered from 2318 birds of 103...

Data from: Microsatellite analysis of genetic diversity and population structure of Arabian horse populations

Anas Khanshour, Eleanore Conant, Rytis Juras & Ernest Gus Cothran
The Arabian horse ignites imagination throughout the world. Populations of this breed exist in many countries, and recent genetic work has examined the diversity and ancestry of a few of these populations in isolation. Here we explore seven different populations of Arabians represented by 682 horses. Three of these are Middle Eastern populations from near the historical origin of the breed, including Syrian, Persian, and Saudi Arabian. The remaining Western populations are found in Europe...

Data from: A global perspective on the trophic geography of sharks

Christopher Stephen Bird, Ana Veríssimo, Sarah Magozzi, Kátya G. Abrantes, Alex Aguilar, Hassan Al-Reasi, Adam Barnett, Dana M. Bethea, Gérard Biais, Asuncion Borrell, Marc Bouchoucha, Mariah Boyle, Edward J. Brooks, Juerg Brunnschweiler, Paco Bustamante, Aaron Carlisle, Diana Catarino, Stéphane Caut, Yves Cherel, Tiphaine Chouvelon, Diana Churchill, Javier Ciancio, Julien Claes, Ana Colaço, Dean L. Courtney … & Clive N. Trueman
Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend across broader geographic ranges if shark taxa display common behavioural traits. By tracking the original site of photosynthetic fixation of carbon atoms that were ultimately assimilated into muscle tissues of 5,394 sharks from 114 species, we identify globally consistent biogeographic traits...

Data from: 3D sorghum reconstructions from depth images identify QTL regulating shoot architecture

Ryan F. McCormick, Sandra K. Truong & John E. Mullet
Dissecting the genetic basis of complex traits is aided by frequent and nondestructive measurements. Advances in range imaging technologies enable the rapid acquisition of three-dimensional (3D) data from an imaged scene. A depth camera was used to acquire images of sorghum (Sorghum bicolor), an important grain, forage, and bioenergy crop, at multiple developmental time points from a greenhouse-grown recombinant inbred line population. A semiautomated software pipeline was developed and used to generate segmented, 3D plant...
