Rove beetles (Coleoptera: Staphylinidae) in yellow birch-dominated stands of southeastern Quebec, Canada: Diversity, abundance, and description of a new species

Abstract

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 were found in uncut stands. In the post-treatment year, 116 species were found in treated (by patch harvesting and ground scarification) and control plots combined. Sixty-one species were common to the two sites, 27 species captured in the 1999 season were not recaptured in the 2000 season, and 55 additional species were captured in 2000. There are 23 new distribution records for Quebec, and one species, Atheta (Dimetrota) pseudomodesta Klimaszewski, sp. nov., is described. New bionomics data on relative abundance, seasonality, and the utility of different trapping methods are presented. Assemblage composition is compared with that of a red spruce (Picea rubens Sarg. (Pinaceae)) forest in New Brunswick.

New records of Canadian Aleocharinae (Coleoptera, Staphylinidae)

“…In the Maritime Provinces it has frequently been recorded in old-growth and mature red spruce (P. rubens) forests in decomposing mushrooms, on bracket fungi, and in compost. In Québec it was recorded in yellow birch (B. alleghaniensis) forests by Klimaszewski et al (2007b). Atheta frosti is newly recorded in British Columbia, Nova Scotia, Ontario, and Québec.…”

New Staphylinidae (Coleoptera) records with new collection data from New Brunswick, Canada. I. Aleocharinae

“…AK, YT, BC, AB, MB, ON, QC, NB, NS (Gusarov 2002b;Klimaszewski and Winchester 2002;Klimaszewski et al 2007b;Gouix and Klimaszewski 2007;Majka and Klimaszewski 2008b;Klimaszewski et al 2008b). Th is transcontinental species was fi rst recorded from New Brunswick in Klimaszewski et al (2005) from the Acadia Research Forest (Sunbury Co.), although it was not noted as being new to the province.…”
