The Elateridae, or click beetles are abundant and diverse in most terrestrial ecosystems in North America, acting as plant pests and filling many other ecological roles. The 112 genera of Elateridae Leach, 1815, or click beetles, known from Canada and USA are included in a first comprehensive digital interactive key to adults. A link to an online p...

The industrial footprint of oil and gas extraction in Alberta, Canada dissects the landscape in a network of linear and polygonal disturbances such as roads and well pads. The changes to biotic and abiotic factors beyond the boundaries of these disturbances into the adjacent ecosystem are called edge effects. A common assumption is that edge effect...

The Palaearctic ten-spotted lady beetle, Adalia decempunctata (Linnaeus), has been confirmed as established in North America, based on morphological characters and DNA barcodes. Its distribution currently appears limited to the Avalon Peninsula of the island of Newfoundland, Canada. Several characters, including the colour of the mesepimera, frons,...

Epigaeic arthropods have been used worldwide as indicators of post-disturbance recovery in many different types of ecosystems. We used them to evaluate the merit of different reclamation prescriptions applied to areas disturbed by oil and gas exploration and extraction. We compared the short-term effects of different mechanical and chemical site pr...

Epigaeic beetle assemblages were surveyed using continuous pitfall trapping during the summers of 1992 and 1993 in six widely geographically distributed locations in Alberta’s aspen-mixedwood forests prior to initial forest harvest. Species composition and turnover (β-diversity) were evaluated on several spatial scales ranging from Natural Regions...

This is the sixth volume in a series of monographs in which we treat the adventive species of the insect order Coleoptera in Canada. The first volume provided an overview of all recorded species of adventive Coleoptera in eastern Canada (Klimaszewski et al. 2010), and the four subsequent volumes reviewed in detail the Canadian adventive species of...

Species loss caused by anthropogenic disturbance threatens forest ecosystems globally. Until 50 years ago, the major sources of boreal forest disturbance in western Canada were a combination of forest wild fire events, pest insect outbreaks, and forest timber harvesting. However, in the 1960s, when the oil boom started in Alberta, oil and gas devel...

The depth at which pitfall traps were sunk into the ground and the resulting catches of epigaeic Carabidae (Coleoptera) and Staphylinidae (Coleoptera) assemblages in subhygric to hydric ecosites with very deep organic soil layers was investigated in the upper foothills ecoregion of Alberta, Canada. Traps were installed at seven sites, with six surf...

Identification guide to all Cerambycidae recognized in Canada and Alaska

Low-impact seismic (LIS) techniques were developed to reduce the environmental footprint of oil exploration. Though relatively narrow (∼2–3 m) and constructed with light-weight equipment, these lines cause forest fragmentation, and with their high density and potential edge influence extending into adjacent forest, their impact may be considerably...

A new species, Anomognathus athabascensis Klimaszewski, Hammond & Langor, sp. n., and nine new provincial records including one new country record of aleocharine beetles are presented for the province of Alberta. Diagnostics, images of habitus and genital structures, distribution, natural history information and new locality data are provided for t...

A synopsis of adventive species of Cucujoidea (Coleoptera) in Canada is presented. Of the 548 Cucujoidea species recorded from Canada, 89 species in 48 genera and 12 families are reported as adventive, constituting 16.1% of the Canadian fauna of Cucujoidea. The majority of adventive species belong to the following families: Cryptophagidae (21 speci...

Four species of Gnathusa Fenyes (G. alfacaribou Klimaszewski & Langor, G. caribou Lohse, G. eva Fenyes, and G. tenuicornis Fenyes) occur in the Nearctic and in Canada. Three species of Ocyusa Kraatz (O. asperula Casey, O. californica Bernhauer, O. canadensis Lohse), and three species of Mniusa Mulsant and Ray (M. minutissima (Klimaszewski & Langor)...

The North American species of Semanotus Mulsant, 1839 are reviewed. Semanotus ligneus (Fabricius, 1787), Semanotus amplus amplus (Casey, 1912) new status, S. amplus basalis (Casey, 1924) new status, Semanotus amplus sequoiae Van Dyke, 1923 new status, Semanotus conformis Casey, 1924 new status, Semanotus terminatus Casey, 1912 new status, Semanotus...

The North American species of Callimoxys Kraatz, 1863 are revised. Callimoxys sanguinicollis (Olivier, 1795), Callimoxys fuscipennis (LeConte, 1861), new status, and Callimoxys pinorum Casey, 1924, new status, are recognized as valid, and two new species (Callimoxys ocularis Hammond and Williams, type locality West Saylorville Lake, Iowa, and Calli...

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...

Aim To evaluate changes in the abundance, species richness and community composition of rove beetles (Coleoptera, Staphylinidae) in response to three configurations of experimental gap cuts and to the effects of ground scarification in early succession yellow birch‐dominated boreal forest. In each experimental treatment, total forest removed was he...

Saproxylic insect assemblages inhabiting dead wood in Canadian forests are highly diverse and variable but quite poorly understood. Adequate assessment of these assemblages poses significant challenges with respect to sampling, taxonomy, and analysis. Their assessment is nonetheless critical to attaining the broad goals of sustainable forest manage...

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 of rearings from wood bolts and window traps attached to snags yielded 9571 beetles representing 257 taxa over the 3-year period (1993-1995). We investigated faunal variation...

Pitfall trapping is a widely used sampling method for biodiversity-related research of ground-dwelling arthropods. The trap is a container, usually with a preservative, that is sunk into the ground to collect arthropods which happen upon the trap perimeter and fall in (Lemieux and Lindgren 1999; Work et al. 2002). Two types receive the most use: de...

The early colonization of newly created coarse woody material (CWM) by beetles was studied in aspen mixedwood forests at two locations in north-central Alberta. Healthy trembling aspen (Populus tremuloides Michx.) trees, in old (> 100 years) and mature (40-80 years) stands, were cut to provide three types of CWM: stumps, bolts on the ground (logs),...

An optimal impact design experiment was established in 1997 to investigate silvicultural alternatives for reducing vulnerability of white spruce (Picea glauca (Moench) Voss) stands to spruce budworm (Choristoneura fumiferana (Clem.)) damage. Ecosystem and insect population responses are being assessed in stands, thinned using a cut-to-length harves...

Arthropods associated with Populus coarse woody material (CWM) were sampled from aspen-mixedwood stands in north-central Alberta using rearings from wood bolts and flight-intercept traps attached to snags. More than 39 000 arthropod specimens were collected over 3 years, comprised mainly of Coleoptera, Diptera, Hymenoptera, and Acari. Detailed anal...

A fire-based conceptual model of forest spatial dynamics is widely embraced as the way to make boreal forest management more ecologically friendly and to conserve biodiversity. However, use of the term "ecosystem based management" does not automatically confer either wisdom or naturalness to resource management tactics. We examine the logical struc...
