Data from: Large herbivores trigger spatiotemporal changes in forest plant diversity

Julien Beguin, Steeve D. Côté & Mark Vellend
Large herbivores can exert top-down control on terrestrial plant communities, but the magnitude, direction, and scale-dependency of their impacts remain equivocal, especially in temperate and boreal forests, where multiple disturbances often interact. Using a unique, long-term and replicated landscape experiment, we assessed the influence of a high density of white-tailed deer (Odocoileus virginianus) on the spatiotemporal dynamics of diversity, composition, and successional trajectories of understorey plant assemblages in recently logged boreal forests. This experiment provided...

Investigating the role of RNA structures in transcriptional pausing using in vitro assays and in silico analyses

Simon Jeanneau, Pierre-Étienne Jacques & Daniel A. Lafontaine
Transcriptional pausing occurs across the bacterial genome but the importance of this mechanism is still poorly understood. Only few pauses were observed during the previous decades, leaving an important gap in understanding transcription mechanisms. Using the well-known Escherichia coli hisL and trpL pause sites as models, we describe here the relation of pause sites with upstream RNA structures suspected to stabilize pausing. We find that the transcription factor NusA influences the pause half-life at leuL,...

General practitioners' attitude towards cooperation with other health professionals in managing patients with multimorbidity and polypharmacy: A cross-sectional study

Hélène Carrier, Anna Zaytseva, Aurélie Bocquier, Patrick Villani, Martin Fortin & Pierre Verger
Cooperation between general practitioners (GPs) and other healthcare professionals appears to help reduce the risk of polypharmacy-related adverse events in patients with multimorbidity. To investigate GPs profiles according to their opinions and attitudes about interprofessional cooperation and to study the association between these profiles and GPs’ characteristics. Between May and July 2016, we conducted a cross-sectional survey of a panel of French GPs about their management of patients with multimorbidity and polypharmacy, focussing on their...

Insect seed and cone predation reduces reproductive potential of treeline conifers across northern Canada

Lucas Brehaut, Katie Goodwin, Kirsten Reid, Anna Crofts, Ryan Danby, Steven Mamet & Carissa Brown
Aim: Altitudinal and latitudinal treeline ecotones have not consistently responded to climate warming the in direction and/or magnitude as predicted by climate alone, suggesting that non-climatic mechanisms (e.g., biotic interactions) are also mediating treeline range dynamics. Through a collaborative research approach, we assessed environmental conditions associated with insect cone granivory and how this biotic interaction may govern the reproductive potential, and therefore range dynamics, of spruce-dominated treelines across northern Canada. Location: Ten boreal forest treelines,...

Data for the article: Trophic niche partitioning between two prey and their incidental predators revealed various threats for an endangered species

Ève Rioux, Fanie Pelletier & Martin-Hugues St-Laurent
Documenting trophic niche partitioning and resource use within a community is critical to evaluate underlying mechanisms of coexistence, competition or predation. Detailed knowledge about foraging is essential as it may influence the vital rates, which, in turn, can affect trophic relationships between species and population dynamics. The aims of this study were to evaluate resource and trophic niche partitioning in summer/autumn between the endangered Atlantic-Gaspésie caribou (Rangifer tarandus caribou) population, moose (Alces americanus) and their...

Data set for combined influence of food availability and agricultural intensification on a declining aerial insectivore

Daniel Garrett
Aerial insectivores show worldwide population declines coinciding with shifts in agricultural practices. Increasing reliance on certain agricultural practices is thought to have led to an overall reduction in insect abundance that negatively affects aerial insectivore fitness. The relationship between prey availability and the fitness of insectivores may thus vary with the extent of agricultural intensity. It is therefore imperative to quantify the strength and direction of these associations. Here we used data from an 11-year...

Data from: Changes in the foliar fungal community between oak leaf flushes along a latitudinal gradient in Europe

Álvaro Gaytán, Ahmed Abdelfattah, Maria Faticov, Xoaquin Moreira, Bastien Castagneyrol, Inge Van Halder, Pieter De Frenne, Camille Meeussen, Bart G. H. Timmermans, Jan P. J. G. Ten Hoopen, Pil U. Rasmussen, Nick Bos, Raimo Jaatinen, Pertti Pulkkinen, Sara Söderlund, Karl Gotthard, Katharina Pawlowski & Ayco J. M. Tack
Aim: To advance our understanding of how foliar fungal communities are structured and assembled, we assessed to what extent leaf flush and latitude can explain the within- and among-tree variation in the foliar fungal community in a foundation tree species, the pedunculate oak Quercus robur. Location: A latitudinal gradient spanning c. 20 degrees in latitude in Europe. Major taxa studied: The foliar fungal community on Quercus robur. Methods: We examined the main and interactive effects...

Post-weaning survival in kangaroos is high and constant until senescence: Implications for population dynamics

Rachel Bergeron, Gabriel Pigeon, David M. Forsyth, Wendy J. King & Marco Festa-Bianchet
Large herbivores typically have consistently high prime-aged adult survival and lower, more variable, juvenile and senescent survival. Many kangaroo populations undergo greater fluctuations in density than other large herbivores, but age- and sex-specific survival of kangaroos and their response to environmental variation remain poorly estimated. We used long-term capture-mark-recapture data on 920 individuals to investigate the survival component of eastern grey kangaroo (Macropus giganteus) population dynamics. Forage availability and population density were monitored quarterly and...

Different proxies, different stories? Imperfect correlations and different determinants of fitness in bighorn sheep

Joanie Van De Walle, Benjamin Larue, Gabriel Pigeon & Fanie Pelletier
Measuring individual fitness empirically is required to assess selective pressures and predict evolutionary changes in nature. There is, however, little consensus on how fitness should be empirically estimated. As fitness proxies vary in their underlying assumptions, their relative sensitivity to individual, environmental, and demographic factors may also vary. Here, using a long-term study, we aimed at identifying the determinants of individual fitness in bighorn sheep (Ovis canadensis) using seven fitness proxies. Specifically, we compared four-lifetime...

Time-course full profiling of circulating miRNAs in neurologically deceased organ donors: a proof of concept study to understand the onset of the cytokine storm

Andrée-Anne Clément, Daphnée Lamarche, Marie-Hélène Masse, Cécilia Légaré, Lee-Hwa Tai, Laurence Fleury Deland, Marie-Claude Battista, Luigi Bouchard & Frédérick D’Aragon
Neurologically deceased organ donors (NDDs) generally display an immune response involving an intense production of pro-inflammatory cytokines referred to as the cytokine storm. The sudden surge of inflammatory mediators in circulation promotes tissue and organ damages and ultimately leads to poor transplant outcome. As microRNAs (miRNAs) are frequently proposed as key regulators of inflammation and are relatively stable in circulation, changes in their profiles could play a role in the onset of the cytokine storm...

Data for: Negative effects of agricultural intensification on the food provisioning rate of a declining aerial insectivore

Daniel Garrett
The historical rise of intensive agricultural practices is hypothesized to be related to declines of grassland and aerial insectivorous birds. Drivers of declines may also influence the overall abundance and spatial distribution of insects within agricultural landscapes. Subsequently, the food provisioning rate of birds breeding within more agro-intensive landscapes may be impacted. Lower provisioning rates in agro-intensive landscapes may lead to reduced growth rate, body condition or fledging success of nestlings but also to diminished...

Dataset used for: Breeding migrations by bighorn sheep males: searching for mates increases vulnerability to hunting

Roxane Lassis, Marco Festa-Bianchet & Fanie Pelletier
In some species where male mating success largely depends on intrasexual competition, males can adopt migratory orresident strategies to seek breeding opportunities. The resulting mixture of resident and migrant tactics within a population can have important ecological, genetic and evolutionary consequences at the metapopulation level. Bighorn sheep Ovis canadensis males establish a linear dominance hierarchy that influences their mating tactics. Some males perform breeding migrations during the pre-rut and rut to seek mating opportunities, but...

A mechanistic model of functional response provides new insights into indirect interactions among arctic tundra prey

Andréanne Beardsell, Andréanne Beardsell, Dominique Gravel, Jeanne Clermont, Dominique Berteaux, Gilles Gauthier & Joël Bêty
Prey handling processes are considered a dominant mechanism leading to short-term positive indirect effects between prey that share a predator. However, a growing body of research indicates that predators are not necessarily limited by such processes in the wild. Density-dependent changes in predator foraging behavior can also generate positive indirect effects but they are rarely included as explicit functions of prey densities in functional response models. With the aim of untangling proximate mechanisms of species...

Data from: Above- and belowground drivers of intraspecific trait variability across subcontinental gradients for five ubiquitous forest plants in North America

Isabelle Aubin, Françoise Cardou, Alison Munson, Madhur Anand, André Arsenault, F. Wayne Bell, Yves Bergeron, Isabelle Boulangeat, Sylvain Delagrange, Nicole J. Fenton, Dominique Gravel, François Hébert, Jill Johnstone, S. Ellen Macdonald, Azim Mallik, Anne C.S. McIntosh, Jennie R. McLaren, Christian Messier, Dave Morris, Bill Shipley, Luc Sirois, Nelson Thiffault, Laura Boisvert-Marsh & Bright B. Kumordzi
Intraspecific trait variability (ITV) provides the material for species adaptation to environmental changes. To advance our understanding of how ITV can contribute to species adaptation to a wide range of environmental conditions, we studied five widespread understory forest species exposed to both continental-scale climate gradients, and local soil and disturbance gradients. We investigated the environmental drivers of between-site leaf and root trait variation, and tested whether higher between-site ITV was associated with increased trait sensitivity...

Data sets for Interacting effects of cold snaps, rain, and agriculture on the fledging success of a declining aerial insectivore

Daniel Garrett
Climate change predicts the increased frequency, duration, and intensity of inclement weather periods, such as unseasonably low temperatures (i.e., cold snaps) and prolonged precipitation. Many migratory species have advanced the phenology of important life history stages, and as a result will likely be exposed to these periods of inclement spring weather more often, thus risking reduced fitness and population growth. For declining avian species, including aerial insectivores, anthropogenic landscape changes such as agricultural intensification are...

Exploration and diet specialization in eastern chipmunks - Québec - Canada

Elouana Gharnit, Melanie Dammhahn, Dany Garant & Denis Réale
Individual diet specialization (IDS) is widespread and can affect the ecological and evolutionary dynamics of populations in significant ways. Extrinsic factors (e.g., food abundance) and individual variation in energetic needs, morphology, or physiology, have been suggested as drivers of IDS. Behavioral traits like exploration and boldness can also impact foraging decisions, although their effects on IDS have not yet been investigated. Specifically, variation among individuals in exploratory behavior and their position along the exploration/exploitation trade-off...
