Different processes drive spatial variation in community composition. Standard measures of composition are useful in species‐based conservation and ecology, but they may be less informative in the context of evolutionary history and functional diversity. Functional and phylogenetic approaches are increasingly used to test mechanisms driving biodive...

The Nearctic fauna of the genus Calamoncosis Enderlein is reviewed. Five species are present in eastern North America: C. carncrossi Nartshuk was recently described from New York; the Palearctic species C. aprica (Meigen) and C. glyceriae Nartshuk are newly recorded, and two new species, C. brooksi and C. munda, are described from eastern North Ame...

Ecological restoration of mined peatlands in North America involves active reintroduction of bog plant species. Animals are not actively reintroduced, thus the re-establishment of peatland fauna must occur either by inoculation along with introduced plant material or by dispersal. We examined the extent to which insects are rein-troduced to restore...

Peat mining causes major degradation to bogs and natural regeneration of these sites is slow and often incomplete. Thus, restoration is an important tool for re-establishing natural ecosystem properties (although perhaps not the original species pool) in mined bogs. Because faunal recovery cannot be taken for granted following plant restoration, we...

Higher Diptera (Schizophora) are taxonomically and ecologically diverse, and include bog specialist and bog-associated species known to respond to peatland disturbance. We examined the effects of three factors (habitat size, vegetation cover and surrounding land use measured in concentric circles of 500, 1000, 1500, and 2000m radii from the samplin...

There is strong evidence that a biodiversity crisis is underway, fuelled by pollution, climate change, and invasive species. These impacts are especially important in northern Canadian regions. However, insect and other arthropod monitoring in Northern Canada urgently needed for land preservation is lacking. This paper presents the Nunavik Sentinel...

During sunny days in Chisasibi last year, grade 5 and 6 students at Waapinichikush Elementary school were running around armed with nets and magnifying glass, lifting rocks and catching all sorts of little creatures when a young girl brought back a nice looking ladybug. What a catch! A special concern species was discovered accidentally! A surprisi...

L’enjeu de la protection de la biodiversité est plus important que jamais et crucial pour l’avenir de nos sociétés. Pourtant, le nombre d’espèces à découvrir et à décrire est aussi grand que le nombre d’espèces déjà connues. La première étape pour prévenir la perte d’espèces est de connaître quelles espèces vivent dans les différents écosystèmes, l...

Lorsque l’on pense à la faune entomologique du Nord du Québec, les mouches noires et les moustiques sont certes les premiers insectes qui nous viennent à l’esprit. Cependant, une diversité d’insectes unique et méconnue est présente et essentielle au fonctionnement des écosystèmes de ce territoire. Certains servent de nourriture aux oiseaux, alors q...

Conservation of biodiversity is growing in interest, and wetlands are disappearing at an alarming rate, so understanding how communities are assembled and how interactions among species and ecosystems influence evolution is critical to the management of threatened habitats. We compared diversity and assemblages of peatland Diptera within and betwee...

Le projet de science participative Les sentinelles du Nunavik est un programme de recherche et d’éducation en entomologie de l'Insectarium de Montréal offert dans toutes les communautés de ce territoire. Il vise à outiller des jeunes de 12 à 17 ans afin d’inventorier, préserver et identifier les insectes et autres arthropodes qui sont présents dans...

The story begins in 2014, when Elise Rioux-Paquette (Kativik Regional Administration-KRG) and Maxim Larrivée (Montreal Insectarium, Space for Life) introduced youngsters from various Nunavik communities to entomology by leading expeditions in national parks in order to inventory the diversity of insects in these protected areas. By sharing their ex...

Vertebrate carcass decomposition studies are typically conducted in spring, summer or autumn, when necrophagous insects are most active. But what happens if an animal dies just before the onset of colder weather and the arrival of snow? To provide preliminary answers, a domestic piglet carcass weighing 30 kg was installed in a deciduous woodland in...

Saproxylic insects, those associated directly or indirectly with decaying wood for all or part of their life cycle, compose a large proportion of forest organisms. Flies(Diptera)are often the most abundant and species-rich group of insects in forest microhabitats, yet most work to date on saproxylic insect diversity and ecology has focused on beetl...

La rivière Beaudette est un lieu de fraie pour diverses espèces de poissons et un sanctuaire de pêche important pour la région de Vaudreuil-Soulanges. Toutefois, elle subit diverses dégradations à la suite du lessivage de sédiments provenant des activités agricoles environnantes et de la dénaturalisation des berges en milieu résidentiel. Le but de...

Background/Question/Methods The impact of climate change on the Arctic is likely to be significant with recent documented changes in sea ice, and phenological shifts in plants and vertebrates. Insects are the dominant animals in northern ecosystems, and climate change could affect insect community structure through trophic cascades caused by chan...

Background/Question/Methods Documenting climate change impacts in northern ecosystems is a current priority in ecology and conservation. Recent research has documented phenological shifts in plants and vertebrates; however, we still lack baseline data to measure the extent of change in many other taxa. Flies (Diptera) are the dominant arthropods...

Canadian peatlands are subject to disturbance and destruction, and drainage for agriculture is responsible for 85% of this degradation. Few studies have explicitly addressed the effects of habitat degradation on arthropod diversity in Nearctic peatlands. Because higher Diptera (Brachycera) in peatlands are diverse, are an important component of foo...

We examined the effect of tree species and decay stage on the abundance, species richness and community composition of saproxylic Diptera associated with decaying logs in southern Quebec. Emergence traps were placed over Sugar Maple and American Beech logs in two decay stages (two and six years after tree death) and insects were collected from May...
