To provide essential knowledge for the development of woodland caribou recovery plans, the Canadian Forest Service initiated an integrative research project in collaboration with the Pessamit Innu community (QC North Shore). The first objective is to mobilize science and indigenous knowledge and perspectives to inform the North Shore caribou recove...

The balsam twig aphid, Mindarus abietinus Koch (Hemiptera: Aphididae), is one of the most important pests of balsam fir ( Abies balsamea (Linnaeus) Miller; Pinaceae) grown as Christmas trees in eastern North America. Aphid feeding on the current-year shoots results in needle distortion and shoots stunting, which reduces the aesthetic value of balsa...

A synopsis of adventive species of Staphylinidae (Coleoptera) in Canada is provided. Of the over 1654 rove beetle species recorded from Canada, 156 species in 76 genera and 13 subfamilies are reported as adventive, constituting about 9.4% of the fauna. The majority of adventive species belong to two subfamilies, Staphylininae (51 species) and Aleoc...

We studied the impacts of increasing size and number of gapcuts and the effects of site preparation by scarification on the species richness and community composition of ground beetles (Coleoptera: Carabidae), using pitfall traps in early-successional yellow birch dominated forests in eastern Canada. Catches of all carabids, forest specialists, and...

The first comprehensive account of adventive species of Coleoptera recorded from Atlantic Canada and Quebec is provided.

Of these, 419 species are recorded from Quebec, 283 from New Brunswick, 357 from Nova Scotia, 198 from Prince Edward Island, and 195 specie...

Forty-eight species of Aleocharinae are newly reported from New Brunswick, bringing the total number of species known from the province to 149. Two of these species, Ocyusa asperula Casey and Myllaena kaskaskia Klimaszewski, are newly recorded for Canada. Additional locality data are presented for nine species recently recorded from the province. C...

A review of the rove beetle species of the genus Gnypeta Thomson from Canada, Alaska and Greenland is presented. Eighteen species are reported from Canada of which 7 are described as new to science, 3 species described from the Palaearctic region are reported in North America for the first time: G. brincki Palm, G. carbonaria (Mannerheim), G. sellm...

Six new aleocharine species are described and illustrated from the Yukon and Alaska: Atheta (Dimetrota) cadeti Klimaszewski and Godin, sp. nov.; Atheta (Hypatheta) pseudomet lakatlana Klimaszewski and Godin, sp. nov.; Cypha inexpectata Klimaszewski and Godin, sp. nov.; Oxypoda yukonensis Klimaszewski and Godin, sp. nov., Oxypoda pseudoconvergens Kl...

Rove beetle assemblages from forest dominated by yellow birch (Betula alleghaniensis Britt. (Betulaceae)) at two sites in southeastern Quebec were characterized in terms of composition, diversity, and relative abundance. In total, 143 species were collected over two seasons (June–August of 1999 and 2000). In the pretreatment year (1999), 88 species...

Eight additional adventive aleocharine beetles, native to the Palaearctic region, are reported from Canada, five of them for the first time. They belong to three tribes: Crataraea suturalis (Mannerheim) (Nova Scotia, Saskatchewan, British Columbia) and “Meotica pallens (Redtenbacher)” (Ontario, British Columbia) belong to Oxypodini; Atheta (Chaetid...

A review of the rove beetle species of the genus Oxypoda Mannerheim from Canada and Alaska is presented. Thirty-seven species are treated, of which 4 have uncertain status, 6 are described as new to science, 8 (excluding new species) represent new distribution records for Canada, 17 (excluding new species) represent new province or territory record...

A review of the Canadian species of the Zyras Stephens group of genera is presented including new diagnoses, distribution maps, colour habitus images and genital illustrations. Colour habitus images, genital line illustrations and a key are provided for all valid species from America north of Mexico. Nearctic Zyras, formerly regarded in a broad sen...

Rove beetle species and their pitfall trap abundance were studied in red spruce (Picea rubens Sarg.; Pinaceae) stands in the Acadia Research Forest, New Brunswick, Canada, in 1999. The study yielded over 5000 specimens representing 134 species in 11 subfamilies of Staphylinidae. Of these, 58 species represent new distribution records for New Brunsw...
