Or, plusieurs esp\u00e8ces de bourdons connaissent un d\u00e9clin marqu\u00e9 de leur occupation en Am\u00e9rique du Nord. Parmi les menaces qui p\u00e8sent sur les bourdons, les changements climatiques sont l&rsquo;une des causes importantes de leur d\u00e9clin. Adapt\u00e9s aux climats froids, ces insectes sont hautement vuln\u00e9rables aux changements climatiques. L\u2019objectif de cette recherche est de comprendre comment les changements climatiques affectent l\u2019occupation des communaut\u00e9s de bourdons du Qu\u00e9bec m\u00e9ridional.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nous avons r\u00e9pertori\u00e9 pr\u00e8s de 57&nbsp;000 mentions de 24 esp\u00e8ces de bourdons allant de 1900 \u00e0 2026 provenant de diverses sources telles que les collections gouvernementales et universitaires, des \u00e9tudes scientifiques, ainsi que des projets de science citoyenne (Bumble Bee Watch et iNaturalist). Pour tenir compte de la provenance des sources, nous avons utilis\u00e9 des mod\u00e8les d\u2019occupation multi-esp\u00e8ces, qui estiment l\u2019occupation tout en corrigeant la probabilit\u00e9 de d\u00e9tection selon la source des donn\u00e9es et le type de bourdons (social ou coucous). Nous avons exclu des mod\u00e8les les esp\u00e8ces principalement distribu\u00e9es dans le nord du Qu\u00e9bec ou repr\u00e9sent\u00e9es par trop peu de mentions pour estimer leur occupation. Un premier mod\u00e8le a \u00e9valu\u00e9 l\u2019\u00e9volution temporelle de l\u2019occupation des bourdons de 1900 \u00e0 2026. Un second mod\u00e8le a \u00e9valu\u00e9 l\u2019effet de la temp\u00e9rature maximale, des pr\u00e9cipitations et du couvert forestier de 1960 \u00e0 2026 sur l\u2019occupation.&nbsp;&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Nos r\u00e9sultats pour le premier mod\u00e8le indiquent un d\u00e9clin de l\u2019occupation de plusieurs esp\u00e8ces, notamment <em>Bombus<\/em><em>&nbsp;<\/em><em>fervidus<\/em>,&nbsp;<em>B. insularis<\/em> et <em>B.<\/em><em>&nbsp;<\/em><em>pensylvanicus.<\/em> Le d\u00e9clin important de&nbsp;<em>B.<\/em><em>&nbsp;<\/em><em>fervidus<\/em>&nbsp;et&nbsp;<em>B. insularis<\/em> est particuli\u00e8rement inqui\u00e9tant, puisque ces esp\u00e8ces ne poss\u00e8dent actuellement aucun statut de conservation au Canada ni au Qu\u00e9bec. Pour les esp\u00e8ces pour lequel le mod\u00e8le ne converge pas, l\u2019analyse descriptive des mentions sugg\u00e8re un d\u00e9clin marqu\u00e9 de&nbsp;<em>B.<\/em><em>&nbsp;<\/em><em>bohemicus<\/em> et un d\u00e9clin de&nbsp;<em>B.<\/em> terricola. D\u2019autres esp\u00e8ces comme&nbsp;<em>B. impatiens<\/em>, <em>B.<\/em><em>&nbsp;<\/em><em>bimaculatus<\/em>,&nbsp;<em>B. griseocollis<\/em>,&nbsp;<em>B.<\/em><em>&nbsp;<\/em><em>borealis<\/em> et&nbsp;<em>B. ternarius<\/em> ont plut\u00f4t vu leur occupation augmenter dans le temps.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Le second mod\u00e8le montre que l\u2019occupation d\u2019esp\u00e8ces comme&nbsp;<em>B. terricola<\/em> et&nbsp;<em>B. insularis<\/em> est n\u00e9gativement associ\u00e9e aux temp\u00e9ratures maximales, mais pas associ\u00e9 aux pr\u00e9cipitations ou au couvert forestier, ce qui sugg\u00e8re une sensibilit\u00e9 aux changements climatiques. \u00c0 l\u2019inverse, l\u2019occupation de&nbsp;<em>B. griseocollis<\/em>&nbsp;et de&nbsp;<em>B. bimaculatus<\/em>&nbsp;est associ\u00e9e positivement aux temp\u00e9ratures \u00e9lev\u00e9es, \u00e9galement sans effet des pr\u00e9cipitations ou du couvert forestier. Cette tendance montre que&nbsp;<em>B. griseocollis<\/em>&nbsp;et de&nbsp;<em>B. bimaculatus<\/em>&nbsp;pourraient b\u00e9n\u00e9ficier des changements climatiques. Le d\u00e9clin temporel de&nbsp;<em>B. terricola<\/em> et <em>B. insularis<\/em> combin\u00e9 \u00e0 leur association n\u00e9gative avec les temp\u00e9ratures chaudes montrent qu\u2019elles sont vuln\u00e9rables aux changements climatiques, alors que des esp\u00e8ces comme&nbsp;<em>B. griseocollis<\/em> et&nbsp;<em>B. bimaculatus<\/em> semblent favoris\u00e9es.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">En bref, cette \u00e9tude montre que les communaut\u00e9s de bourdons du Qu\u00e9bec m\u00e9ridional se transforment. Les esp\u00e8ces comme&nbsp;<em>B. impatiens<\/em>,&nbsp;<em>B. bimaculatus, B. ternarius<\/em> et&nbsp;<em>B. griseocollis<\/em> occupent de plus en plus le territoire au profit d\u2019esp\u00e8ces en d\u00e9clin comme&nbsp;<em>B. fervidus<\/em>,&nbsp;<em>B. terricola<\/em> et&nbsp;<em>B. insularis<\/em>. Derri\u00e8re ces changements, l\u2019augmentation des temp\u00e9ratures est l\u2019un des facteurs qui affectent le plus les communaut\u00e9s de bourdons, ce qui sugg\u00e8re que les changements climatiques pourraient \u00eatre un moteur important des changements de la communaut\u00e9 de bourdons. <em><\/em>Nos r\u00e9sultats appuient l\u2019\u00e9valuation du statut de conservation de&nbsp;<em>B. fervidus<\/em>&nbsp;et&nbsp;<em>B. insularis<\/em> et la protection de l\u2019habitat d\u2019esp\u00e8ces en d\u00e9clin comme&nbsp;<em>B. bohemicus, B. pensylvanicus, B. terricola.<\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>Estimation de l\u2019occupation des bourdons du Qu\u00e9bec m\u00e9ridional&nbsp;: tendances temporelles et facteurs environnementaux Auteurs Maxence Poirier-Joanette , Fr\u00e9d\u00e9ric McCune, Joseph Moisan-De Serres, Colin Favret, Sophie Cardinal, Leif Richardson, Marc J.
