“…Th e present study found 135 species of beetles unrecorded from Nova Scotia by Bousquet (1991). Both studies thus contribute to ongoing programs to document the distribution, abundance, origins, and trophic categories of the beetle fauna of the province which are essential for many ecological, zoogeographic, and environmental monitoring studies (McCorquodale et al 2005). Some specimens derived from this study have already contributed to recent surveys of the Coleoptera fauna of the region (Bousquet and Laplante 2006;Majka , 2006bMajka , 2007aMajka , 2007cMajka , 2008aCline 2006a, 2006b;Majka and Johnson 2008;Majka and Pollock 2006;Majka et al , 2007aMajka et al , 2007a).…”

Old-growth forests in Nova Scotia typically exhibit an uneven-aged, multi-layered stand structure and contain signifi cant amounts of coarse woody debris. Many forest species, including invertebrates, depend in various ways on deadwood substrates. Th e objective of this study was to investigate relationships between forest stand age, silvicultural treatment, dead wood, and invertebrate biodiversity, using saproxylic beetles as an indicator group. Saproxylic beetle communities were also compared in the context of other studies in Nova Scotia. Beetles were gathered using four collection techniques: pitfall traps, funnel traps, sweep-netting, and manual searching. Results show that both stand age and harvest treatment had an eff ect on species richness and species composition. Younger stands had lower species richness and hosted a signifi cantly diff erent suite of species than medium-aged or older ones. Similarly, harvested stands had lower species richness and were host to a signifi cantly diff erent suite of species than unharvested stands. Th e results from the investigation of stand age are of particular interest. Forest management that disregards the dependence of diff erent suites of beetles on forest stands of various ages and compositions, emphasizing even-aged single-species stands, may be harmful to the species diversity of Nova Scotia's forest ecosystems.

The Nitidulidae and Kateretidae of the Maritime provinces of Canada are surveyed. Forty-eight species are now known to occur in the region. Twenty-six are newly recorded in Nova Scotia and nine are newly recorded on Prince Edward Island. One Palearctic species, Soronia grisea (L.), is reported for only the second time in North America. Six other nonnative species have been intercepted. One new synonym, Glischrochilus sanguinolentussanguinolentus (Olivier, 1790) (= Glischrochilus sanguinolentusrubromaculatus (Reitter, 1873) syn. nov.), is designated. Cape Breton and Prince Edward Island appear to have a depauperate fauna, perhaps reflecting an island-related diminution of species, a comparative lack of collection effort, or a combination of both. An examination of the Nova Scotia fauna indicates several distribution patterns within the province. Introduced species constitute a sizeable component of the region's fauna, with four new introductions being reported here.

“…This discovery does underscore the importance of on-going monitoring programs which can detect changes in both the distributions of adventive species which may be colonizing new areas and environments, and of native species which may be responding to environmental change. McCorquodale et al (2005) point out that another necessary requisite for detection is a reservoir of taxonomic expertise and well-curated reference collections which can facilitate the processes of recognition and status assessment of such species.…”

The Palearctic byrrhids Chaetophora spinosa (Rossi) and Simplocaria semistriata (F.) are reported for the first time from Prince Edward Island (PEI), the former species for the first time from Atlantic Canada from specimens collected in 2003–05. Their presence is discussed both in light of the history of introductions of exotic species in Atlantic Canada in general, and on PEI in particular, and also in the context of the effect of adventive species on native organisms and ecosystems. These discoveries underscore the need for continual monitoring of invertebrate populations to detect ongoing introductions of adventive species. The native byrrhid Cytilus alternatus (Say) is also reported for the first time from PEI.
