Polyploid spermatozoa in Pityogenes chalcographus and Ips typographus (Coleoptera: Scolytidae) [PDF]
European Journal of Entomology, 2004 Abnormal spermatogenesis in Pityogenes chalcographus (L.) and Ips typographus (L.) results in oversized spermatozoa in all the populations investigated. They can be identified by light microscopy and classified as 2n up to 16n polyploid.

Ecology, Volume 104, Issue 12, December 2023., 2023 Abstract Biodiversity drives ecosystem processes, but its influence on deadwood decomposition is poorly understood. To test the effects of insect diversity on wood decomposition, we conducted a mesocosm experiment manipulating the species richness and functional diversity of beetles.

Spatial distribution of saproxylic beetles on trunks of standing Scots pine trees
Agricultural and Forest Entomology, Volume 25, Issue 4, Page 601-611, November 2023., 2023 Abstract The spatial distribution of saproxylic beetles landing and climbing stems of 12 grown and healthy Scots pine trees (Pinus sylvestris L.) was examined in detail during a 3‐year trial. The beetles were sampled using sticky traps attached to the tree trunk at three tree parts (i.e., the trunk base, middle part of the trunk, and trunk in crown ...

Climate‐driven tree growth and mortality in the Black Forest, Germany—Long‐term observations
Global Change Biology, Volume 29, Issue 20, Page 5908-5923, October 2023., 2023 This study describes climate‐driven tree mortality and tree growth in the Black Forest mountain range in Germany. It is based on a 68‐year consistent data series describing the annual mortality of all trees growing in a forest area of almost 250 thousand ha. The climatic water balance is identified as the main driver of mortality and tree growth.

Evolutionary ecology of the bark beetlesIps typographusandPityogenes chalcographus
Bulletin of Entomological Research, 2022 AbstractIps typographus(L.) andPityogenes chalcographus(L.) (Coleoptera: Curculionidae) are two common bark beetle species on Norway spruce in Eurasia. Multiple biotic and abiotic factors affect the life cycles of these two beetles, shaping their ecology and evolution. In this article, we provide a comprehensive and comparative summary of selected life-
