| 英文摘要 | Climate change is disproportionately impacting the North, and northern arthropods are particularly vulnerable to disturbances. The Dempster Highway is a gravel road that crosses the northern Yukon Territory in Canada, and wolf spiders (Araneae: Lycosidae) are the top arthropod predators on the tundra in this region. We investigated the effects of the Dempster Highway on subarctic tundra wolf spider abundance, phenology, and community composition by actively sampling 8 paired plots near (20 m) and far (200 m) from the road. Species richness did not differ with distance from the road, but total wolf spider abundance was much lower near the road, and this was driven by decreased abundance of the dominant tundra wolf spider species, Pardosa lapponica (). The overall proportion of females carrying egg sacs was higher near the road, suggesting advanced phenology in response to increased temperatures near the road. Together, these results indicate that the Dempster Highway impacts tundra wolf spider communities, which may have important consequences for food web dynamics and ecosystem function.Les changements climatiques ont un impact plus important sur le Nord, et les arthropodes nordiques sont particuli & egrave;rement vuln & eacute;rables aux perturbations. La route Dempster est une route de gravier qui traverse le nord du territoire du Yukon au Canada, et les araign & eacute;es-loups (Araneae: Lycosidae) sont d'importants pr & eacute;dateurs d'arthropodes de la toundra de cette r & eacute;gion. Nous avons & eacute;tudi & eacute; les effets de la route Dempster sur l'abondance, la ph & eacute;nologie et la composition de la communaut & eacute; des araign & eacute;es-loups de la toundra subarctique en & eacute;chantillonnant activement huit parcelles appari & eacute;es proches (20 m) et & eacute;loign & eacute;es (200 m) de la route. La richesse des esp & egrave;ces ne diff & eacute;rait pas avec la distance par rapport & agrave; la route, mais l'abondance totale d'araign & eacute;es-loups & eacute;tait inf & eacute;rieure pr & egrave;s de la route, et cela peut & ecirc;tre attribu & eacute; & agrave; une diminution de l'abondance de l'esp & egrave;ce dominante d'araign & eacute;es-loups de la toundra, Pardosa lapponica (). La proportion globale des femelles portant des cocons & eacute;tait plus & eacute;lev & eacute;e pr & egrave;s de la route, sugg & eacute;rant une ph & eacute;nologie avanc & eacute;e en r & eacute;ponse & agrave; l'augmentation des temp & eacute;ratures pr & egrave;s de la route. Ces r & eacute;sultats indiquent que, globalement, la route Dempster a un impact sur les communaut & eacute;s d'araign & eacute;es-loups de la toundra, ce qui peut avoir des cons & eacute;quences importantes sur la dynamique du r & eacute;seau trophique et le fonctionnement de l'& eacute;cosyst & egrave;me. |
