Ecological IndicatorsThe increasingly severe and frequent forest damage caused by the European spruce bark beetle ( Ips typographus ) has been systematically surveyed across Europe since the early 2000s, yet underlying drivers remain not fully understood.

Integrative 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.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females
Integrative Zoology, EarlyView.We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

The conservation of saproxylic beetles in boreal forest [PDF]
, 2006 Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decreased in abundance and many species are threatened ...

IPS INFESTATION – A GLOBAL PROBLEM FOR CONIFEROUS IN THE FACE OF CLIMATE CHANGE
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2021 Bark beetle infestation (Coleoptera: Curculionidae, Scolytinae) is a relevant issue for forestry sector at global scale. In Europe, the average wood lost because infestations was approximately 2.9 million m3/year in the last half of the twentieth century.

Microbiota‐Mediated Sequential Gallery Colonization by Adults and Larvae of an Invasive Bark Beetle
Integrative Zoology, EarlyView.Dispersing adult beetles harbor more pinitol‐degrading microbes to colonize novel host pines with high levels of pinitol stress. These microbes from the beetle's exoskeleton and gut will be transmitted into the gallery via adults’ feeding and frass, whose proliferation in the gallery contributes to the formation of a low‐pinitol microhabitat.

Agricultural and Forest Entomology, EarlyView.The persistence and health of ash populations were characterized in post‐outbreak forests near the epicentre of the emerald ash borer (EAB) invasion in North America. Regenerating ash remained abundant, but densities of understory ash were higher in wetlands (hydric), while ash remained at the seedling stage in riparian (mesic) and upland (xeric ...

Cross-attraction between an exotic and a native pine bark beetle: a novel invasion mechanism? [PDF]
PLoS ONE, 2007 Aside from the ecological impacts, invasive species fascinate ecologists because of the unique opportunities that invasives offer in the study of community ecology.

The dual crisis: Climate change simultaneously drives pollinator decline and pest outbreaks
Agricultural and Forest Entomology, EarlyView.Climate change acts as an asymmetric ecological filter, favouring r‐selected pest traits (rapid reproduction, generalism) while disadvantaging K‐selected pollinators. For every 1°C of warming, bee species richness declines ~25% since the 1990s, while pest‐induced crop losses increase by 10%–25%. A network‐centric approach integrating climate‐responsive

Host desiccation and interspecific competition limit reproductive performance of a bark beetle
Agricultural and Forest Entomology, EarlyView.At high and moderate phloem moisture levels, Polygraphus proximus reproductive success was suppressed by sympatric species density. At low phloem moisture, P. proximus reproductive success was suppressed by the low phloem moisture regardless of the Cryphalus laricis hole density. Conspecific density (i.e., attack density of P.
