High intercontinental migration rates and population admixture in the sapstain fungus Ophiostoma ips

open access: yes, 2007
Ophiostoma ips is a common fungal associate of various conifer-infesting bark beetles in their native ranges and has been introduced into non-native pine plantations in the Southern Hemisphere.

Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Isolation, Expression Profiling, and Regulation via Host Allelochemicals of 16 Glutathione S-Transferases in the Chinese White Pine Beetle, Dendroctonus armandi

open access: yesFrontiers in Physiology, 2020
The Chinese white pine beetle (Dendroctonus armandi) is undoubtedly one of the most important pests causing ecological damage in the Qinling Mountains. When bark beetles invade conifers, they must overcome host tree defenses, including primary resistance

Dead wood retention and the risk of bark beetle attack [PDF]

open access: yes, 2002
Wind-felled Norway spruce trees left for conservation purposes and spruce stems stored as forest fuel may be colonised by the bark beetles Ips typographus and Pityogenes chalcographus (Coleoptera: Scolytidae).

Decreasing water availability reduces productivity in Swiss forests along an altitudinal gradient

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Forests are one of the most important terrestrial carbon sinks, but are increasingly under pressure due to drought, heat and the occurrence of extreme events. There are opposing longer term trends for European forest growth reported, and severe drought and disturbance ...

Ecological and social factors lead to variation in parental care between sexes in a burying beetle

open access: yesInsect Science, EarlyView.
We experimentally investigated the effects of ecological (resource availability and interspecific competition) and social factors (intraspecific competition) on parental care and reproductive success in the burying beetle Nicrophorus vespilloides. Our results showed that males and females adjust their parental care based on resource availability and ...

Olfaction in the Spruce Bark Beetle, Ips typographus [PDF]

open access: yes, 2011
The bark beetle Ips typographus regularly kills spruce trees in the Palearctic. Spruces are colonized by means of attraction to an aggregation pheromone. Attraction is modulated by anti-attractive volatiles (NHV) from non-host plants.

The impact of forest management on saproxylic beetles and other arthropods in a semi-deciduous forest in Southern Benin [PDF]

open access: yes, 2004
Tropical forest ecosystems worldwide are suffering from anthropogenic pressures leading to deforestation and forest degradation, and resulting in a loss of biodiversity.

Volumetric Comparison of Overall Brain and Neuropil Size Between Social and Non‐social Spiders: Exploring the Social Brain Hypothesis

open access: yesIntegrative Zoology, EarlyView.
Brain size may be influenced by the cognitive demands of sociality (social brain hypothesis). We used microCT to compare CNS and brain volumes in social versus solitary huntsman and crab spiders. Social huntsman spiders had larger arcuate and mushroom bodies, while social crab spiders had larger visual neuropils.

An Overview of Genes From Cyberlindnera americana, a Symbiont Yeast Isolated From the Gut of the Bark Beetle Dendroctonus rhizophagus (Curculionidae: Scolytinae), Involved in the Detoxification Process Using Genome and Transcriptome Data

open access: yesFrontiers in Microbiology, 2019
Bark beetles from Dendroctonus genus promote ecological succession and nutrient cycling in coniferous forests. However, they can trigger outbreaks leading to important economic losses in the forest industry.
