Effects of Clear-Cut Harvesting on Boreal Ground-Beetle Assemblages (Coleoptera: Carabidae) in Western Canada
Pitfall catches from four types of mature lodgepole pine—white spruce forest with those from five age classes of young forest regenerating subsequent to clear-cutting are compared, suggesting that there is a general pattern of recovery after logging.
Northern forestry and carabids: the case for concern about old-growth species
This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about the timber-farming activities of the Northern Forest Service in Alberta.
Sampling carabid assemblages with pitfall traps: The madness and the method
Ecological studies of carabid populations and assemblages using pitfall traps may be improved if they are both designed and interpreted in light of the biology of the group and with regard to the deficiencies of pitfall trapping.
Arthropod responses to harvesting and wildfire: Implications for emulation of natural disturbance in forest management
Carabid beetle assemblages (Coleoptera, Carabidae) across urban-rural gradients: an international comparison
We studied communities of carabid beetles in residual forest patchesalong urban-suburban-rural gradients in three cities (Helsinki, Finland; Sofia,Bulgaria and Edmonton, Canada) to examine their…
The search for common anthropogenic impacts on biodiversity: a global network
We introduce an initiative to assess and compare landscape changes related to human activities on a global scale, using a single group of invertebrates. The GLOBENET programme uses common field…
Pitfall Trap Size and Capture of Three Taxa of Litter-Dwelling Arthropods: Implications for Biodiversity Studies
For the purposes of ecological monitoring, using more small pitfall traps would be the most efficient sampling technique to characterize the dominant epigaeic arthropod fauna; small traps collect few nontarget vertebrates, and sorting the samples involves generally less processing time.
Habitat associations and seasonal activity of ground-beetles (Coleoptera, Carabidae) in central Alberta
Carabid beetles were collected with grids of pitfall traps during two seasons in five habitats in the ecotone between aspen parkland and boreal mixedwood forest in central Alberta, and the consistency of aggregation among particular traps suggests that it is mainly a response to subtle microhabitat differences.
Succession of boreal forest spider assemblages following wildfire and harvesting
To test whether spider succession following harvest differed from succession following wildfire, spiders were collected by pitfall trapping and sweep netting over two years in aspen-dominated boreal…
Budbreak Phenology and Natural Enemies Mediate Survival of First-Instar Forest Tent Caterpillar (Lepidoptera: Lasiocampidae)
It is hypothesized that a narrow phenological window in host quality after budbreak and its interaction with natural enemies has exerted strong selective pressure on larvae to emerge from eggs as early as possible in the spring and that this window is a potent force in determining the dynamics of low density populations of tent caterpillars.
