Invasions by non-indigenous species are a problem of increasing magnitude and threaten the stability world's ecosystems economies. Despite enormity this problem, relatively little is known about importance various invasion pathways. Using historical records interceptions alien insects in air passenger baggage USDA inspectors, we characterize as an pathway. The most commonly infested commodity intercepted inspectors was fruit (mainly tropical fruits), were Homoptera Diptera. Numbers from...
Machine learning, an important branch of artificial intelligence, is increasingly being applied in sciences such as forest ecology. Here, we review and discuss three commonly used methods machine learning (ML) including decision-tree neural network, support vector their applications four different aspects ecology over the last decade. These include: (i) species distribution models, (ii) carbon cycles, (iii) hazard assessment prediction, (iv) other management. Although ML approaches are...
Cost-effective and ecologically sensitive monitoring techniques are required to assess effects of anthropogenic disturbances on biodiversity. Pitfall trapping is widely used in biodiversity programs measure the diversity organisms active within leaf-litter. We compared catch rates species richness ground beetles (Coleoptera: Carabidae), rove Staphylinidae), spiders (Araneae) across five different diameters pitfall traps (4.5, 6.5, 11, 15, 20 cm) three sizes rain covers (64, 79.2, 225 cm2)...
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...
Recovery of biodiversity and other ecosystem functions to pre‐disturbance levels is a central goal natural disturbance‐based approaches management. In boreal mixedwood forests, green‐tree retention has been proposed as an alternative approach traditional clearcutting that may minimize initial displacement species assemblages speed recovery the biota. Here we evaluated effectiveness six dispersed for conservation ground beetle in four cover types span gradient stand development following...
Abstract The National Ecological Observatory Network ( NEON ) will monitor ground beetle populations across a network of broadly distributed sites because beetles are prevalent in food webs, sensitive to abiotic factors, and have an established role as indicator species habitat climatic shifts. We describe the design population sampling context 's long‐term, continental‐scale monitoring program, emphasizing design, priorities, collection methods. Freely available data associated field...
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...
Deadwood-associated insects and saprotrophic fungi are principal agents of wood decomposition in boreal forest. Silvicultural treatments that alter microclimate availability deadwood likely affect composition growth rates both insect fungal communities, leading to changes rates. Here, we relate saproxylic beetle dominant polypore assemblages with woody environmental variables experimental partial cuts, clearcuts, uncut controls using a series causal models determine the relationship between...
Abstract Rove beetles are useful subjects for Nearctic forest biodiversity work because they abundant, diverse, and easily collected, have strong habitat affinities. Excellent identification keys exist most groups, although there is a dearth of ecological life-history information. There considerable variation in species composition abundance within the active summer season from year to year. Community varies among larger geographical regions lesser extent types more localized areas. Within...
Multi-cohort management that creates or maintains an uneven structure within forest stands has been widely advocated as a means to attenuate the impact of harvesting. An experimental network was put in place black spruce forests northwestern Québec test this assertion. Here we synthesize biodiversity results two main lessons: (1) at least 40% 60% retention pre-harvest basal area required maintain conditions for most species groups; (2) partial harvests showed potential be efficient deadwood...
Increased interest in biomass harvesting for bioenergetic applications has raised questions regarding the potential ecological consequences on forest biodiversity. Here we evaluate initial changes abundance, species richness and community composition of rove (Staphylinidae) ground beetles (Carabidae), immediately following 1) stem-only (SOH), which logging debris (i.e., tree tops branches) are retained site, 2) whole-tree (WTH), stems, branches removed mature balsam fir stands Quebec,...
Fruit preference by birds is a complex process based upon the morphology and spatial arrangement of fruits on physiological needs capabilities birds. In North America, most can be divided into two groups nutritional content: those rich in sugars relative to lipids, lipids sugars. To investigate how fruit may change seasonally determine if it correlated with state, we designed simple laboratory experiment using American Robins (Turdus migratorius) artificial fruits. During summer autumn,...
ABSTRACT Aim To evaluate changes in the abundance, species richness and community composition of rove beetles (Coleoptera, Staphylinidae) response to three configurations experimental gap cuts effects ground scarification early succession yellow birch‐dominated boreal forest. In each treatment, total forest removed was held constant (35% removal by partial cutting with a concomitant decrease size) but number gaps increased (two, four eight gaps, respectively), resulting an increase amount...
Partial harvesting has been proposed as a key aspect to implementing ecosystem management in the Canadian boreal forest. We report on replicated experiment located mixedwoods of Northwestern Quebec. In winter 2000–2001, two partial treatments, one using dispersed pattern, and second, which created (400 m2) gap were applied 90-year-old aspen-dominated mixed stand. The design also included clear cut control. Over course following eight years, live tree, coarse woody debris, regeneration ground...
Abstract We tested the immediate and delayed effects of a low-intensity prescribed fire on beetles, ants termites inhabiting log sections cut from moderately decomposed pine trees in southeastern United States. also explored co-occurrence patterns among these insects. Half logs were placed at site scheduled for while rest assigned to neighboring not be burned. then collected insects emerging sets immediately after as well 2, 6, 26 52 weeks. The had little effect number beetles although...
In western Canada, some forestry companies are attempting to incorporate conservation of biodiversity as a new management priority. Here we provide review strategies currently implemented through survey in this region. Representatives from fourteen were asked complete 30 questions designed assess six broad issues, all which important for integrating protection with timber production. Differences provincial legislation major factor contributing the prioritization objectives. All stressed that...

We studied the impacts of increasing size and number gapcuts effects site preparation by scarification on species richness community composition ground beetles (Coleoptera: Carabidae), using pitfall traps in early-successional yellow birch dominated forests eastern Canada. Catches all carabids, forest specialists, generalists were generally higher uncut controls than treatments. The catch open-habitat specialists was lower Although not significant, there a common trend for to decrease...
Experimental research on beetle responses to removal of logging residues following clearcut harvesting in the boreal balsam fir forest Quebec revealed several abundant rove (Staphylinidae) species potentially important for long-term monitoring. To understand trophic affiliations these ecosystems, it was necessary analyze their gut contents. We used microscopic and molecular (DNA) methods identify contents beetles: Atheta capsularis Klimaszewski, klagesi Bernhauer, Oxypoda grandipennis...
We tested the response of species composition three dominant litter-dwelling arthropod taxa (carabid beetles, spiders, and rove beetles) to wildfire harvest. This study was conducted in north-central Ontario (47°42′N, 83°36′W) jack pine (Pinus banksiana Lamb.) dominated stands 2013 using pitfall trapping. Using 222 (12 015 individuals), we compared effects disturbance recently burned (3 years since fire) clearcut sites harvest; tree length, full tree, stump removal, blading), as well older,...
We assessed lepidopteran communities in replicated stands representing two hardwood forest ecosystems northern Michigan during a 3-yr period that coincided with the first gypsy moth outbreaks experienced by this area. Adult Lepidoptera were collected at 4-wk intervals each summer 1993–1995 eight stands. Four classified as ecological landtype phase (ELTP) 20, and they dominated oaks (Quercus spp.), favored host of moth, Lymantria dispar (L.). The other four ELTP 45, species few preferred...
