Data from: Seeing is believing? comparing plant-herbivore networks constructed by field co-occurrence and DNA barcoding methods for gaining insights into network structures

Chunchao Zhu, Dominique Gravel & Fangliang He
Plant-herbivore interaction networks provide information about community organization. Two methods are currently used to document pairwise interactions among plants and insect herbivores. One is the traditional method that collects plant-herbivore interaction data by field observation of insect occurrence on host plants. The other is the increasing application of newly developed molecular techniques based on DNA barcodes to the analysis of gut contents. The second method is more appealing because it documents realized interactions. To construct...

Data from: Data management, archiving and sharing for biologists and the role of research institutions in the technology-oriented age

Sebastien Renaut, Amber E. Budden, Dominique Gravel, Timothée Poisot & Pedro Peres-Neto
Data are one of the primary outputs of science. Although certain sub-disciplines of biology have pioneered efforts to ensure their long-term preservation and facilitate collaborations, data continue to disappear, owing mostly to technological, regulatory and ideological hurdles. In this review, we describe the important steps towards proper data management and archiving, and provide a critical discussion on the importance of long term data conservation. We then illustrate the rise in data archiving through the Joint...

Data from: Assessing changes in arthropod predator-prey interactions through DNA-based gut content analysis - variable environment, stable diet

Bernhard Eitzinger, Nerea Abrego, Dominique Gravel, Tea Huotari, Eero J. Vesterinen & Tomas Roslin
Analyzing the structure and dynamics of biotic interaction networks and the processes shaping them is currently one of the key fields in ecology. In this paper, we develop a novel approach to gut content analysis, thereby deriving a new perspective on community interactions and their responses to environment. For this, we use an elevational gradient in the High Arctic, asking how the environment and species traits interact in shaping predator-prey interactions involving the wolf spider...

Data from: Local adaptation of trees at the range margins impact range shifts in the face of climate change

Kevin A. Solarik, Christian Messier, Rock Ouimet, Yves Bergeron & Dominique Gravel
The ability of tree species to track their climatic niche at rates comparable to global warming is concerning, particularly if they are constrained by local adaptation. If a species is locally adapted at its range margin it could be beneficial for range expansion as it ensures that the genotypes colonizing new areas are the fittest because environmental conditions are more similar to the current ones. In trees, local adaptation can slow range expansion when climate...

Data from: Genomic analysis of morphometric traits in bighorn sheep using the Ovine Infinium® HD SNP BeadChip

Joshua M. Miller, Marco Festa-Bianchet & David W. Coltman
Elucidating the genetic basis of fitness-related traits is a major goal of molecular ecology. Traits subject to sexual selection are particularly interesting, as non-random mate choice should deplete genetic variation and thereby their evolutionary benefits. We examined the genetic basis of three sexually selected morphometric traits in bighorn sheep (Ovis canadensis): horn length, horn base circumference, and body mass. These traits are of specific concern in bighorn sheep as artificial selection through trophy hunting opposes...

Data from: Interactions among trees: a key element in the stabilising effect of species diversity on forest growth

Raphaël Aussenac, Yves Bergeron, Dominique Gravel & Igor Drobyshev
1.There is mounting evidence that species diversity increases the temporal stability of forest growth. This stabilising effect of diversity has mainly been attributed to species differences in their response to fluctuating environmental conditions. Interactions among individuals could also contribute to the stabilising effect of diversity by increasing the mean and reducing the variance of tree growth, however, this has never been directly demonstrated. 2.We used tree‐ring width chronologies from temperate and boreal mixed stands of...

Cost-effectiveness analysis of telerehabilitation for people who have sustained a stroke with return home without intensive rehabilitation: A systematic review

Data from: Genetic decline, restoration and rescue of an isolated ungulate population

Marc-Antoine Poirier, David W. Coltman, Fanie Pelletier, Jon Jorgenson & Marco Festa-Bianchet
Isolation of small populations is expected to reduce fitness through inbreeding and loss of genetic variation, impeding population growth and compromising population persistence. Species with long generation time are the least likely to be rescued by evolution alone. Management interventions that maintain or restore genetic variation to assure population viability are consequently of significant importance. We investigated, over 27 years, the genetic and demographic consequences of a demographic bottleneck followed by artificial supplementation in an...

Data from: Electrically induced verbal perseveration: a striatal deafferentation model

Emmanuel Mandonnet, Guillaume Herbet, Sylvie Moritz-Gasser, Isabelle Poisson, Francois Rheault & Hugues Duffau
Objective: The present study aimed to elucidate the neural correlates of the deafferentation cognitive model of verbal perseveration (VP) by analyzing the connectomics of the sites where electrical stimulation elicited VP during awake left glioma surgery. Methods: We retrospectively reviewed the anatomical sites that generated VP when electrically stimulated, in a series of 21 patients operated on while awake for a left glioma. Each stimulation point was manually located on the postoperative MRI and then...

Data from: Characterizing the contribution of plasticity and genetic differentiation to community-level trait responses to environmental change

Geneviève Lajoie & Mark Vellend
The match between functional trait variation in communities and environmental gradients is maintained by three processes: phenotypic plasticity and genetic differentiation (intraspecific processes), and species turnover (interspecific). Recently, evidence has emerged suggesting that intraspecific variation might have a potentially large role in driving functional community composition and response to environmental change. However, empirical evidence quantifying the respective importance of phenotypic plasticity and genetic differentiation relative to species turnover is still lacking. We performed a reciprocal...

Data from: A range-wide domino effect and resetting of the annual cycle in a migratory songbird

Elizabeth A. Gow, Lauren Burke, David W. Winkler, Samantha M. Knight, Robert G. Clark, Marc Bélisle, Lisha L. Berzins, Tricia Blake, Eli S. Bridge, Russell D. Dawson, Peter O. Dunn, Dany Garant, Geoff Holroyd, Andrew G. Horn, David J.T. Hussell, Olga Lansdorp, Andrew J. Laughlin, Marty L. Leonard, Fanie Pelletier, Dave Shutler, Lynn Siefferman, Caz M. Taylor, Helen Trefry, Carol M. Vleck, David Vleck … & D. Ryan Norris
Latitudinal differences in timing of breeding are well documented but how such differences carry over to influence timing of events in the annual cycle of migratory birds is not well understood. We examined geographic variation in timing of events throughout the year using light-level geolocator tracking data from 133 migratory tree swallows (Tachycineta bicolor) originating from 12 North American breeding populations. A swallow’s breeding latitude influenced timing of breeding, which then carried over to affect...
