We compared pitfall catches from four types of mature lodgepole pine—white spruce forest with those five age classes young regenerating subsequent to clear‐cutting. Ground beetles were most abundant in the youngest sites (1–2 years since cutting) and stands on moist soil. Species richness was higher than forest. Cluster analysis grouped ground‐beetle fauna according type, suggesting that there is a general pattern recovery after logging. Responses common species cutting fell into three...
Abstract The potential for mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), to expand its historical range in North America from west of the continental divide into eastern boreal forest was assessed on basis analyses effects climate and weather brood development survival, key aspects interaction beetle with hosts associated organisms. Variation suitability high host susceptibility create a finite risk establishment local persistence low-level...
Much of Canada’s terrestrial biodiversity is supported by boreal forests. Natural resource development in forests poses risks to this biodiversity. This paper reviews the scientific literature assess effects natural on Canadian We address four questions: (1) To what extent have changed due development? (2) How has responded these changes? (3) Will second-growth converge with that primary forests? (4) Are we losing species from focus trees, understory plants, insects, fungi, selected mammals,...
To test whether spider succession following harvest differed from wildfire, spiders were collected by pitfall trapping and sweep netting over two years in aspen‐dominated boreal forests. Over 8400 individuals 127 species of identified 12 stands representing three age‐classes (stand origin 1995, 1982, 1968) disturbance types (wildfire harvesting). The diversity assemblages tended to be higher fire‐origin than harvest‐origin stands; the youngest also supported more even distributions species....
This study examines the short-term impact of forest soil compaction and organic matter removal on mesofauna, in general, oribatid mite species, particular. Both reduced density mesofauna. Stem-only harvesting total mesofauna densities by 20% relative to uncut values. A combination whole-tree harvest floor with heavy significantly 93% control. Removal represents a substantial loss habitat for most The apparently buffered mineral limiting both fluctuations temperature moisture. abundance...
Saproxylic beetles associated with Populus coarse woody material were sampled from two age classes of fire-origin aspen stands in north-central Alberta, Canada. A combination rearings wood bolts and window traps attached to snags yielded 9571 representing 257 taxa over the 3-year period (19931995). We investigated faunal variation across regions, stand ages (mature, 6090 years; old, >100 years), decay classes, types, years terms species richness, abundance, trophic differences. Although...
Conservation of biological diversity under the natural disturbance model boreal forest management relies on assumption that mosaics stand composition and structure can be adequately recreated through activities. Maintaining compositional structural features provide adequate habitat for species within managed stands is basis coarse-filter conservation strategies. Here we test effect epigaeic arthropod fauna from four mixedwood cover types in western Canada. We observed differences community...
Rising societal demands for forest resources along with existing natural disturbance regimes suggest that sustainable management will increasingly depend on better understanding the cumulative effects of and anthropogenic disturbances. In North America, example, there is increasing economic pressure to salvage log burned forests, although ecological consequences combining fire harvesting same sites are unclear. We examined short-term (2 year) responses boreal ground beetles (Coleoptera:...
The Canadian Phalacridae are briefly surveyed. Two species, Phalacrus politus Melsheimer and Olibrus vittatus LeConte, newly recorded in Canada. As a result, eight phalacrids now known to occur Thirteen new provincial records reported including one from Saskatchewan, two Manitoba, New Brunswick, three Nova Scotia, Prince Edward Island, Newfoundland Labrador. four species ten of provinces Atlantic Canada the first this family region. Information on bionomics these is summarized. include...
The early colonization of newly created coarse woody material (CWM) by beetles was studied in aspen mixedwood forests at two locations north-central Alberta. Healthy trembling (Populus tremuloides Michx.) trees, old (>100 years) and mature (4080 stands, were cut to provide three types CWM: stumps, bolts on the ground (logs), suspended above simulate snags. Over 2 years, 1049 Coleoptera, representing 49 taxa, collected. Faunal structure differed little between locations. Species diversity...
Abstract 1 Saproxylic insects, a functional group dominated by beetles, are dependent on dead or moribund trees as habitat elements. 2 Although there few studies of saproxylic insects from the North American boreal zone, European demonstrate that forest harvest can lead to biologically significant decrease in beetle diversity. 3 We studied beetles mixedwood using flight intercept traps established naturally and girdled trembling aspen spruce along successional gradient undisturbed stands...
Abstract Saproxylic insect assemblages inhabiting dead wood in Canadian forests are highly diverse and variable but quite poorly understood. Adequate assessment of these poses significant challenges with respect to sampling, taxonomy, analysis. Their is nonetheless critical attaining the broad goals sustainable forest management because such species disproportionately threatened elsewhere by reductions generally associated commercial exploitation northern forests. The composition saproxylic...
The Leiodidae (the round fungus beetles, the small carrion and mammal nest beetles) of Atlantic Canada (New Brunswick, Newfoundland Labrador, Nova Scotia, Prince Edward Island) are surveyed. Twenty five species, including Colon (Colon) politum Peck Stephan, (Myloechus) forceps Hatch, incisum schwarzi Hydnobius arizonensis Horn, Anogdus dissimilis Blatchley, potens (Brown), Cyrtusa subtestacea (Gyllenhal), Leiodes puncticollis (Thompson), rufipes (Gebler), Agathidium atronitens Fall,...
Abstract Our objective was to assess the potential of carabid beetles (Coleoptera: Carabidae) as effective bioindicators effects forest management at a Canadian national scale. We present comparison beetle assemblages reported from large-scale studies across Canada. Based on initial response following disturbance treatment, we found that consistently responded disturbance, but responses individual species and changes in composition were nested within context regional geography finer scale...
Summary Mountain pine beetles (MPB) are the most serious pest of lodgepole in Canada and likely to invade boreal jack forests. MPB vector three blue‐stain fungi, Grosmannia clavigera , Ophiostoma montium Leptographium longiclavatum which contribute beetle success. Fungal survival at extreme temperatures will their success pine. Growth, sporulation fungi −20 37°C were tested vitro . Overwintering G. O. was assessed vivo All species grew 5–30°C, with optimal growth 20–25°C. L. survived −20°C,...
Eighteen species of Cryptophaginae are now known to occur in Atlantic Canada. Eight these including Cryptophagus difficilis Casey, jakowlewi Reitter, laticollis Lucas, mainensis tuberculosus Maklin, Pteryngium crenatum (Gyllenhal), Telmatophilus americanus LeConte and Caenoscelis basalis newly recorded Canada; one which, C. mainensis, is Canada, another, laticollis, eastern North America. Nineteen new provincial records reported with the result that five from New Brunswick, 14 Nova Scotia,...
