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

open access: yesGlobal 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.

Addressing a century‐old hypothesis – do pioneer beetles of Ips typographus use volatile cues to find suitable host trees?

open access: yesNew Phytologist, Volume 238, Issue 5, Page 1762-1770, June 2023., 2023
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.

Symbiosis and pathogenicity of Geosmithia and Talaromyces spp. associated with the cypress bark beetles Phloeosinus spp. and their parasitoids

open access: yesEnvironmental Microbiology, Volume 24, Issue 8, Page 3369-3389, August 2022., 2022
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,

Lost in dead wood? Environmental DNA sequencing from dead wood shows little signs of saproxylic beetles

open access: yesEnvironmental DNA, Volume 4, Issue 3, Page 654-660, May 2022., 2022
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.

Cambioxylophagous fauna developing on logging residues of blue spruce (Picea pungens Engelmann)

open access: yesJournal of Forest Science, 2011
Cutting down 20- to 30-years-old trees of blue spruce (Picea pungens Engelm.) (October, May) and cross-cutting them to sections of different volume (0.5-75 dm3) under conditions of half-shade × open area resulted in a potential food offer for ...

Host tree and insect genetic diversity on the borderline of natural distribution: a case study of Picea abies and Pityogenes chalcographus (Coleoptera, Scolytinae) in Greece

open access: yesSilva Fennica, 2011
Picea abies (L.) Karst. and Pityogenes chalcographus constitute a commonly observed host tree–insect association in Eurasia, with the natural distribution of the bark beetle overlapping that of Norway spruce.

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).

Exploitation of kairomones and synomones by Medetera spp. (Diptera: Dolichopodidae), predators of spruce bark beetles

open access: yesEuropean Journal of Entomology, 2005
The semiochemical relationships in a predator-prey-host plant system were studied by a series of multiple-choice field assays. The studied system included predatory flies of the genus Medetera (Diptera: Dolichopodidae), the bark beetles Ips typographus ...

Spatial distribution of four spruce bark beetles in north-western Slovakia

open access: yesJournal of Forest Science, 2007
Infestation density of four the most common spruce bark beetle species was estimated on 15 study sites (10 trees per site) in the Kysuce model region in 2006.
