Spatial distribution of saproxylic beetles on trunks of standing Scots pine trees
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 ...

Evolutionary ecology of the bark beetlesIps typographusandPityogenes chalcographus
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-

Climate‐driven tree growth and mortality in the Black Forest, Germany—Long‐term observations
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.

Summary Global warming and more frequent climate extremes have caused bark beetle outbreaks of unprecedented scale of these insects in many conifer forests world‐wide. Conifers that have been weakened by drought and heat or damaged by storms are highly susceptible to bark beetle infestation.

Summary Fungi associated with cypress bark beetles are practically unknown in the Eastern Mediterranean. Our study focused on the fungi associated with the body parts and galleries of two indigenous cypress bark beetles, Phloeosinus armatus and P. bicolor, sampled from Cupressus sempervirens trees in different regions in Israel. Arbitrarily primed PCR,

The needs for alternative methods for monitoring arthropods are increasing. We here tested eDNA metabarcoding for saproxylic beetles in dead wood. While a few samples showed traces of beetle DNA, the method needs to be improved. Our study makes a first step in developing a thorough protocol for approved application.

Mutually inclusive mechanisms of drought‐induced tree mortality
A better understanding of the mechanisms driving drought‐induced tree mortality is necessary to improve predictions of forest responses to climate extremes. We use data from a tree diversity experiment to model the individual mortality risk of 9435 young trees from 12 temperate tree species, one third of which died following a severe drought in 2018 ...

Increasing tree diversity may reduce the risk of bark beetle infestation for genera prone to high infestation rates (Picea and Larix), but risk for less preferred genera (Pinus, and to some extent the exotic tree species) may increase with tree diversity due to spillover from preferred hosts.

Erroneous conclusions about current geographical distribution and future expansion of forest insects in Northern Sweden: comments on Hof and Svahlin (2015) [PDF]
We question the validity of the results and the conclusions from a study entitled The potential effect of climate change on the geographical distribution of insect pest species in the Swedish boreal forest that was recently published in Scandinavian ...

On the genus Bursaphelenchus Fuchs, 1937 (Nematoda: Parasitaphelenchinae) associated with wood and insects from declining forest trees in the Czech Republic [PDF]
An overview of the genus Bursaphelenchus in the Czech Republic is presented, based on a recent survey for monitoring the presence of the pinewood nematode, Bursaphelenchus xylophilus, as well as on previous reports of this genus in the country.
