Colloque du CSBQ -2020 QCBS Symposium

La théorie de l'entropie maximale de l'écologie (mieux connue sous son acronyme anglais METE) prédit plusieurs distributions macroécologiques d'intérêt en biologie de la conservation. À partir d'une poignée de variables d'état caractérisant une communauté biologique (e.g... Read More →

There has been a resurgent interest in Indigenous traditional food systems and wildlife use, however recent documentation of traditional harvest is lacking for northern Quebec. Detailed harvest surveys by the James Bay and Northern Québec Native Harvesting Research Committee for... Read More →

La connaissance des niches écologiques des pathogènes opportunistes (OP) est essentielle à la lutte contre les infections nosocomiales. Dans ce cadre, nous avons évalué la distribution et la diversité génétique de trois OP dans les éviers. Des échantillons de drains et robinets... Read More →

Les abeilles sauvages et les syrphes sont des pollinisateurs d’une grande importance. Au Québec, ils ont largement été étudiés en milieu agricole, mais très peu en milieu forestier. Les interrogations sont nombreuses concernant l’effet du climat futur sur ces organismes... Read More →

The landscape between the Laurentian Mountains in Québec and the Adirondack Mountains in New York State is one of three north-south wildlife movement linkages that connect natural areas in Southeastern Canada with Northeastern United States. This region boasts a wide variety of habitats... Read More →

To date, Québec’s forests have experienced major transformations as a result of human activities and ongoing anthropogenic pressures promise to further alter forest biodiversity patterns. Contemporary forests grow on lands with variable histories of land-use (e.g., timing and intensity... Read More →

Property rights are fundamental institutions that set the rules for who is allowed to use, manage, and control natural resources. The literature on property rights over natural resources is well developed. However, property rights also govern who can obtain ecosystem services that... Read More →

Tropospheric trace gases concentrations are greatly regulated by soil bacteria consumption, which in turns have a tremendous impact on Earth’s climate. Hence, gaining knowledge about the ecophysiology of these bacteria, regarding various soil conditions as well as varying gas exposures... Read More →

Le paradigme caractérisant l‘interaction plante-microbiome cite l’exsudation de molécules solubles ou volatiles: acides organiques, acides gras, métabolites secondaires, protéines antimicrobiennes, acides aminés, ADN extracellulaire et sucres. Toutefois, nos résultats préliminaires... Read More →

For organisms living in seasonal environments, timing is key. It has been widely documented that Arctic and temperate seabird species follow seasonal pulses, matching their breeding events with productivity peaks. However, this idea has been much less explored in tropical species... Read More →

Herbivore defoliation has a major effect on temperate forest degradation, and it is important to have a good understanding of the damages it causes. Herbivore distribution and damages seen on leaves can be affected by various abiotic and environmental factors including vertical stratification... Read More →

Infectious diseases cause devastating illnesses in humans, crops, and livestock, among others. And despite our knowledge and the multiple strategies to reduce transmission, we still have outbreaks from known pathogens and the emergence of new diseases, without mention how these transmission...

Reduction of sea ice coverage in the sea ice in recent years across the Canadian Arctic has led to higher shipping activity for most types of vessels navigating Canadian Arctic waters. Expected increases in shipping across the Arctic may pose a danger of collision and shipwreck along... Read More →

Les toits verts sont de plus en plus utilisés comme des outils de mitigations contre les îlots de chaleur et pour la gestion des eaux pluviales. On reconnait maintenant le rôle essentiel du microbiome du sol pour de nombreuses fonctions écosystémiques. Cependant, on en connaît... Read More →

Comprendre comment l’environnement d’un organisme façonne son comportement sexuel et de survie est important si on souhaite expliquer la diversité qu’on observe en nature. Pour ce faire, il est utile d’étudier ces comportements chez des espèces où les générations successives... Read More →

Zostera marina is a prominent macrophyte in the temperate North Atlantic. Eelgrasses fulfill many ecological roles in coastal waters. They consolidate seabed, attenuate wave energy, and provide a hatchery, nursery, and shelter habitat for many species. In doing so, eelgrass meadows... Read More →

At the end of the summer, tundra birds leave the tundra and often travel thousands of kilometers to reach diverse habitats such as the grasslands of South America, the shorelines of the Atlantic coast and the upwelling zones in West Africa. Habitats used as stopover sites and overwintering... Read More →

Les individus d’un grand nombre d’espèces montrent des différences de comportement constantes dans le temps et les situations. Pourquoi observe-t-on ces différences, alors que le processus de la sélection naturelle fait généralement tendre les traits phénotypiques vers... Read More →

Les dérèglements climatiques actuels constituent une menace pour la biodiversité planétaire et les services écosystémiques qui lui sont liés. Lorsque les conditions climatiques varient de manière abrupte, comme observé en ce moment, les organismes vivants peuvent soit s’adapter... Read More →

Human population and its growing demands have triggered the worldwide erosion of biodiversity and instilled trade-offs amongst the ecosystem services we depend upon. Nevertheless, biodiversity and ecosystem services loss can still be attenuated if proactive and anticipatory strategies... Read More →

L’accroissement d’évènements climatiques extrêmes liés aux changements globaux inflige de lourdes perturbations de plus en plus perceptibles sur les écosystèmes forestiers. En effet, les forêts mondiales accuseraient déjà une forte mortalité liée à des évènements... Read More →

There are many anthropogenic threats to the health and biodiversity of pollinators. However, wild bees can often thrive in urban areas. This is attributed to several factors, including the planting of many ornamental flowers and edible plants, as well as weedy floral species growing... Read More →

Plants are constantly defending themselves against herbivory and coping with their surroundings. When we think of a defense, thorns and spines come to mind. However, a diverse system of chemical compounds is also produced by the plants to survive in their environment. These compounds... Read More →

Le blocage d’espèces indésirables (exotiques ou natives) est un enjeu particulièrement important dans le contexte des sols mis à nu lors d’activités humaines spécifiques. L'hypothèse de la résistance biotique à l’invasion (RBI) soutient que les communautés les plus... Read More →

In ecosystems, matter such as detritus can have different roles like being recycled and consumed by organisms (resource effect) or acting as substrate or a structural component of the environment (non-resource effect). As most ecological models focus on one or the other of these roles... Read More →

co-presentation with Jake LawlorClimate change biogeography is a subject of increasing attention in recent years as species redistribute across environmental gradients in space. Empirical observations of species range shifts that have already occurred offer critical insights into... Read More →

The main defoliators of white spruce (Picea glauca) in mixed wood forest (Cook et al., 1978, MacLean and Ebert, 1999) and plantations (Hall et al., 1994) are outbreaking insects which cause great losses in the production of lumber. To identify the most damaging herbivorous species... Read More →
