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...

Effects of temperature on mating behaviour and mating success: a meta-analysis

Natalie Pilakouta & Anais Baillet
In light of global climate change, there is a pressing need to understand how populations will respond to rising temperatures. Understanding the effects of temperature changes on mating behaviour is particularly important, given its implications for population viability. To this end, we performed a meta-analysis of 53 studies to examine how temperature changes influence mating latency, choosiness, and mating success. We hypothesized that if higher temperatures make mate searching and mate assessment more costly due...

Genome-wide methylation in the panmictic European eel (Anguilla anguilla)

Shenglin Liu, Aja Noersgaard Buur Tengstedt, Magnus W. Jacobsen, Jose Martin Pujolar, Bjarni Jónsson, Javier Lobón-Cervià, Louis Bernatchez & Michael M. Hansen
The role of methylation in adaptive, developmental and speciation processes has attracted considerable interest, but interpretation of results is complicated by diffuse boundaries between genetic and non-genetic variation. We studied whole genome genetic and methylation variation in the European eel, distributed from subarctic to subtropical environments, but with panmixia precluding genetically based local adaptation beyond single-generation responses. Overall methylation was 70.9%, with hypomethylation predominantly found in promoters and first exons. Redundancy analyses involving juvenile glass...

Impacts of indoor mass storage of two densities of honey bee queens (Apis mellifera) during winter on queen survival, reproductive quality and colony performance

Mireille Levesque, Andrée Rousseau & Pierre Giovenazzo
Spring imports of queen honey bees (Apis mellifera L.) are essential to replace winter colony losses in Canada, but contribute to the spread of treatment-resistant strains of pathogens and undesirable genetic traits. A possible alternative to these imports is the mass storage of queens during winter. By overwintering a strong colony (queen bank) containing large numbers of mated queens isolated in cages, beekeepers could acquire local queens early in the spring. In this study, we...

Design and validation of a 63K genome-wide SNP-genotyping platform for caribou/reindeer (Rangifer tarandus)

Alexandra Carrier, Julien Prunier, William Poisson, Mallorie Trottier-Lavoie, Isabelle Gilbert, Maria Cavedon, Kisun Pokharel, Juha Kantanen, Marco Musiani, Steeve D. Côté, Vicky Albert, Joëlle Taillon, Vincent Bourret, Arnaud Droit & Claude Robert
Abstract Background Development of large single nucleotide polymorphism (SNP) arrays can make genomic data promptly available for conservation problematic. Medium and high-density panels can be designed with sufficient coverage to offer a genome-wide perspective and the generated genotypes can be used to assess different genetic metrics related to population structure, relatedness, or inbreeding. SNP genotyping could also permit sexing samples with unknown associated metadata as it is often the case when using non-invasive sampling methods...

Evidence for synergistic cumulative impacts of marking and hunting in a wildlife species.

Frédéric LeTourneux, Gilles Gauthier, Roger Pradel, Josée Lefebvre & Pierre Legagneux
Non-additive effects from multiple interacting stressors can have unpredictable outcomes on wildlife. Stressors that initially have negligible impacts may become significant if they act in synergy with novel stressors. Wildlife markers can be a source of physiological stress for animals and are ubiquitous in ecological studies. Their potential impacts on vital rates may vary over time, particularly when changing environments impose new stressors. In this study, we evaluated the temporal changes in the combined impact...

Genome-scale phylogeography resolves the native population structure of the Asian longhorned beetle, Anoplophora glabripennis (Motschulsky)

Mingming Cui, Yunke Wu, Marion Javal, Isabelle Giguère, Géraldine Roux, Jose Andres, Melody Keena, Juan Shi, Baode Wang, Evan Braswell, Scott Pfister, Richard Hamelin, Amanda Roe & Ilga Porth
Human assisted movement has allowed the Asian longhorned beetle (ALB, Anoplophora glabripennis (Motschulsky)) to spread beyond its native range and become a globally regulated invasive pest. Within its native range of China and the Korean peninsula, human-mediated dispersal has also caused cryptic translocation of insects, resulting in population structure complexity. Previous studies used genetic methods to detangle this complexity but were unable to clearly delimit native populations which is needed to develop downstream biosurveillance tools....

Individual-based eco-evolutionary models for understanding adaptation in changing seas

Amanda Xuereb, Quentin Rougemont, Peter Tiffin, Huijie Xue & Megan Phifer-Rixey
As climate change threatens species’ persistence, predicting the potential for species to adapt to rapidly changing environments is imperative for the development of effective conservation strategies. Eco-evolutionary individual-based models (IBMs) can be useful tools for achieving this objective. We performed a literature review to identify studies that apply these tools in marine systems. Our survey suggested that this is an emerging area of research fueled in part by developments in modeling frameworks that allow simulation...

Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top-down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non-resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements limit our current understanding of how much of the circum-Arctic variation in defence compounds is explained by taxa or defence functional groups (resinous/non-resinous). We measured circum-Arctic...

Coping with seasonality: dynamics of adult body mass and survival in an alpine hibernator

Béatrice Carrier, Sandra Hamel, Mathieu Garel & Steeve Côté
Alpine mammals are highly vulnerable to current and projected climate change because they are confined to a certain elevation range. Physiological and behavioural adaptations in burrowing species, such as finding shelter in burrows when the summer conditions are unfavorable and hibernating in winter during the stressful period of resource shortage, could partly buffer the negative impacts of these forecasted changes. We studied the links between environmental factors and annual variations in adult mass and survival...

Occupancy modeling of habitat use by white-tailed deer after more than a decade of exclusion in the boreal forest

Aimie Baribeau, Jean-Pierre Tremblay & Steeve Côté
The exclusion of herbivores in forest areas is a strategy used to reduce the impact of selective browsing and increase the regeneration of desired plant species. On Anticosti Island (Québec, Canada), selective browsing by white-tailed deer prevents the regeneration of balsam fir – white birch forests leading to their conversion into white spruce forests. Large deer exclosures were established for ca . 10 to 12 years in clear-cuts with patches of residual forest from 2001...

Multibeam bathymetry from an Autonomous Underwater Vehicule (AUV) - Pointe-des-Monts (2019-2020)

Patrick Lajeunesse & Alexandre Normandeau
Using an autonomous underwater vehicle (HUGIN) equipped with an EM2040 multibeam echosounder, submarine canyons and channels offshore Pointe-des-Monts were surveyed in 2019 and 2020. This survey aimed at identifying the fine-scale morphological variability of turbidity current bedforms on the modern seafloor. This project was funded by Réseau Québec-Maritime.

Plant litter chemistry controls coarse-textured soil carbon dynamics

Raoul Huys, Vincent Poirier, Malo Bourget, Catherine Roumet, Stephan Hattenschwiler, Nathalie Fromin, Alison Munson & Grégoire Freschet
1. As soils store more carbon (C) than the Earth’s atmosphere and terrestrial biomass together, the balance between soil C uptake in the form of soil organic matter and release as CO2 upon its decomposition is a critical determinant in the global C cycle regulating our planet’s climate. Although plant litter is the predominant source of C fueling both soil C build-up and losses, the issue of how litter chemistry influences this balance remains unresolved....

Impact of COVID-19 on the Prescribing Pattern of Oral Anticoagulants for Atrial Fibrillation After Cardiac Surgery

Dannick Brochu, Amélie St-Arnaud, Louis-Étienne Marchand, Pierre Voisine & Julie Méthot
Background:Because of logistic challenges associated with the COVID-19 pandemic, direct oral anticoagulants (DOAC) were favored over warfarin in patients presenting postoperative atrial fibrillation (AF) after cardiac surgery in our institution. Considering the limited evidence supporting the use of DOAC in this context, we sought to evaluate the safety and efficacy of this practice change.Methods:A retrospective study was performed with patients from the Quebec City metropolitan area who were hospitalized at the Institut universitaire de cardiologie...

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 from: Shifts in growth light optima among diatom species support their succession during the spring bloom in the Arctic

Dany Croteau, Thomas Lacour, Nicolas Schiffrine, Philippe-Israël Morin, Marie-Hélène Forget, Flavienne Bruyant, Joannie Ferland, Augustin Lafond, Douglas Campbell, Jean-Éric Tremblay, Marcel Babin & Johann Lavaud
Diatoms of the Arctic Ocean annually experience extreme changes of light environment linked to photoperiodic cycles and seasonal variations of the snow and sea-ice cover extent and thickness which attenuate light penetration in the water column. Arctic diatom communities exploit this complex seasonal dynamic through a well-documented species succession during spring, beginning in sea-ice and culminating in massive phytoplankton blooms underneath sea-ice and in the marginal ice zone. The pattern of diatom taxa sequentially dominating...

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...

Tree identity and diversity directly affect soil moisture and temperature but not soil carbon ten years after planting

Marc-Olivier Martin-Guay, Michaël Belluau, Benoît Côté, Ira Tanya Handa, Mark Jewell, Rim Khlifa, Alison Munson, Maxime Rivest, Joann Whalen & David Rivest
1. Soil C is the largest C pool in forest ecosystems that contributes to C sequestration and mitigates climate change. Tree diversity enhances forest productivity, so diversifying the tree species composition, notably in managed forests, could increase the quantity of organic matter being transferred to soils, and alter other soil properties relevant to the C cycle. 2. A ten-year-old tree diversity experiment was used to study the effects of tree identity and diversity (functional and...

Seascapes and foraging success: movement and resource discovery by a benthic marine herbivore

Kathleen MacGregor & Ladd Johnson
1. Spatially concentrated resources result in patch-based foraging, wherein the detection and choice of patches as well as the process of locating and exploiting resource patches involve moving through an explicit landscape composed of both resources and barriers to movement. An understanding of behavioural responses to resources and barriers is key to interpreting observed ecological patterns. 2. We examined the process of resource discovery in the context of a heterogeneous seascape using sea urchins and...
