A heterozygous moth genome provides insights into herbivory and detoxification
The first whole-genome sequence of a basal lepidopteran species, Plutella xylostella, is reported, which contains 18,071 protein-coding and 1,412 unique genes with an expansion of gene families associated with perception and the detoxification of plant defense compounds.
Insect community composition and trophic guild structure in decaying logs from eastern Canadian pine-dominated forests
An integrated model for snag and downed woody debris decay class transitions
Evidence of interaction between Sirex noctilio and other species inhabiting the bole of Pinus
Findings suggest that co‐habiting beetles could negatively affect S. noctilio population dynamics over time, and the potential mechanisms for this interaction are discussed.
Exotic earthworm distribution in a mixed-use northern temperate forest region: influence of disturbance type, development age, and soils
The impacts of invasive earthworms in northern North American forests include mixing of soil and litter horizons, changes to nutrient availability, and shifts in understory plant communities.…
Patterns in the within‐tree distribution of the emerald ash borer Agrilus planipennis (Fairmaire) in young, green‐ash plantations of south‐western Ontario, Canada
The emerald ash borer is a serious exotic pest of ash trees (Fraxinus spp.) in North America, and is responsible for the deaths of millions of trees in Ontario and Michigan.

It is found that plant diversity significantly declined with increasing richness of introduced earthworm ecological groups, and there is evidence that introduced earthworms are associated with declines in plant diversity in North American forests.
Effect of host availability on reproduction and survival of the parasitoid wasp Trichogramma minutum
The ability of parasitoids to adjust their fecundity schedule as an adaptation to changing host resources and discuss the findings with regard to theories of life history evolution are considered.
Assessment of Trichogramma species for biological control of forest lepidopteran defoliators
The results suggest that T. minutum has the greatest potential for biological control against various forest lepidopteran pests and that the black army cutworm may be the best target candidate for further study.
Tree cover and species composition effects on academic performance of primary school students
The proportion of tree cover, as distinct from other types of “green space” such as grass, was found to be a significant positive predictor of student performance, accounting for 13% of the variance explained in a statistical model predicting mean student performance assessments.
