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:Physiological effects of increased foraging effort in a small passerine

Kang Nian Yap, Oh Run Kim, Karilyn C Harris & Tony D Williams
Foraging to obtain food, either for self-maintenance or at presumably elevated rates to provision offspring, is thought to be an energetically demanding activity but one that is essential for fitness (higher reproductive success and survival). Nevertheless, the physiological mechanisms that allow some individuals to support higher foraging performance, and the mechanisms underlying costs of high workload, remain poorly understood. We experimentally manipulated foraging behaviour in zebra finches (Taeniopygia guttata) using the technique described by Koetsier...

Data from: Amphibian species' traits, evolutionary history, and environment predict Batrachochytrium dendrobatidis infection patterns, but not extinction risk

Dan A. Greenberg, Wendy J. Palen & Arne Ø. Mooers
The fungal pathogen Batrachochytrium dendrobatidis (Bd) has emerged as a major agent of amphibian extinction, requiring conservation intervention for many susceptible species. Identifying susceptible species is challenging, but many aspects of species’ biology are predicted to influence the evolution of host resistance, tolerance, or avoidance strategies towards disease. In turn, we may expect species exhibiting these distinct strategies to differ in their ability to survive epizootic disease outbreaks. Here we test for phylogenetic and trait-based...

Hakai Institute Juvenile Salmon Program

Brett Johnson, Julian Gan, Sean Godwin, Krystal Bachen, Tim van der Stap & Brian Hunt
Fall 2017 Version 1.0 Background: The Hakai Institute Juvenile Salmon Program was launched in the spring of 2015 in a collaborative partnership with UBC, SFU, Salmon Coast, Pacific Salmon Foundation, and DFO. The program operates in the Discovery Islands and Johnstone Strait (Figure 1) and thus provides information on the health of juvenile Fraser River salmon after passage through: 1) Strait of Georgia – stratified high plankton biomass zone; and 2) Discovery Islands & Johnstone...

Data from: Classifying three imaginary states of the same upper extremity using time-domain features

Mojgan Tavakolan, Zack Frehlick, Xinyi Yong & Carlo Menon
Brain-computer interface (BCI) allows collaboration between humans and machines. It translates the electrical activity of the brain to understandable commands to operate a machine or a device. In this study, we propose a method to improve the accuracy of a 3-class BCI using electroencephalographic (EEG) signals. This BCI discriminates rest against imaginary grasps and elbow movements of the same limb. This classification task is challenging because imaginary movements within the same limb have close spatial...

Data from: A genetic locus for paranoia

Bernard Crespi, Silven Read, Iiro Salminen & Peter Hurd
The psychological effects of brain-expressed imprinted genes in humans are virtually unknown. Prader-Willi syndrome (PWS) is a neurogenetic condition mediated by genomic imprinting, which involves high rates of psychosis characterized by hallucinations and paranoia, as well as autism. Altered expression of two brain-expressed imprinted genes, MAGEL2 and NDN, mediates a suite of PWS-related phenotypes, including behavior, from studies of mice. We phenotyped a large population of typical individuals for schizophrenia-spectrum and autism-spectrum traits, and genotyped...

Data from: Transitions between phases of genomic differentiation during stick-insect speciation

Rüdiger Riesch, Moritz Muschick, Dorothea Lindtke, Romain Villoutreix, Aaron A. Comeault, Timothy E. Farkas, Kay Lucek, Elizabeth Hellen, Víctor Soria-Carrasco, Stuart R. Dennis, Clarissa F. De Carvalho, Rebecca J. Safran, Cristina P. Sandoval, Jeff Feder, Regine Gries, Bernard J. Crespi, Gerhard Gries, Zach Gompert & Patrik Nosil
Speciation can involve a transition from a few genetic loci that are resistant to gene flow to genome-wide differentiation. However, only limited data exist concerning this transition and the factors promoting it. Here, we study phases of speciation using data from >100 populations of 11 species of Timema stick insects. Consistent with early phases of genic speciation, adaptive colour-pattern loci reside in localized genetic regions of accentuated differentiation between populations experiencing gene flow. Transitions to...

Data from: Global biogeography of mating system variation in seed plants

David A. Moeller, Ryan D. Briscoe Runquist, Annika M. Moe, Monica A. Geber, Carol Goodwillie, Pierre-Olivier Cheptou, Christopher G. Eckert, Elizabeth Elle, Mark O. Johnston, Susan Kalisz, Richard H. Ree, Risa D. Sargent, Mario Vallejo-Marin & Alice A. Winn
Latitudinal gradients in biotic interactions have been suggested as causes of global patterns of biodiversity and phenotypic variation. Plant biologists have long speculated that outcrossing mating systems are more common at low than high latitudes owing to a greater predictability of plant–pollinator interactions in the tropics; however, these ideas have not previously been tested. Here, we present the first global biogeographic analysis of plant mating systems based on 624 published studies from 492 taxa. We...

Data from: Ecological legacies of anthropogenic burning in a British Columbia coastal temperate rain forest

Kira M. Hoffman, Ken P. Lertzman & Brian M. Starzomski
Aim Few long-term fire histories have been reconstructed in coastal temperate rain forests, and little is known regarding the spatial and temporal characteristics of lightning and human ignitions. We use a multidisciplinary approach to assess the impact, scale and ecological legacies of historic fires. Location We focus on perhumid temperate rain forests located on the central coast of British Columbia, Canada. Methods We reconstructed 700 years of temporal and spatial aspects of fire activity with...

Data from: The SETDB2 locus: evidence for a genetic link between handedness and atopic disease

Bernard Crespi, Silven Read & Peter Hurd
The gene SETDB2, which mediates aspects of laterality in animal model systems, has recently been linked with human handedness as measured continuously on a scale from strong left to strong right. By contrast, it was marginally associated with a left-right dichotomous measure, and it showed no evidence of association with absolute handedness strength independent of direction. We genotyped the SETDB2 handedness-associated single nucleotide polymorphism, rs4942830, in a large healthy population likewise phenotyped for continuous, absolute,...
