🌲🪳 Tree mortality caused by insects is on the rise in Europe. Warm, dry regions are the most severely affected. New study in @globalchangebio.bsky.social www.wsl.ch/en/news/tree... #Forests #ClimateChange #Treemortality #Barkbeetles
Tree mortality from insects is rising across Europe
In Europe, more trees are dying from insect infestations. Broadleaves cope better than conifers, as heat and drought worsen the issue.

#LiteratureNotice Chase et al. The role of propagule pressure in experimental #BarkBeetles invasions doi.org/10.1111/1365...
#Beetle #Beetles #Weevils #BiologicalInvasions
Colonization rates of Ips pini in relation to numbers of propagules released (log scale) in (a) 1 m caged and (b) 10 m field scenarios. Colonization was defined as at least one billet out of four per release replicate having at least one F1 adult present. Each data point represents one release replicate. A binomial generalized linear model was fit to the data to produce each line.

A plot from the field choice experiment. Fresh-cut Norway spruce and Sitka spruce logs are arranged in an alternating ‘open’ square, with a low-dose pheromone lure attached to a central post. This plot is located at the forest edge; the timber stack is visible in the background in corner of the clearfell.

Abbreviated single gene COX1 phylogeny of Euwallacea fornicatus with sequences from the newly collected specimens from Spain. Calculated using FastTree2. See https://doi.org/10.5281/zenodo.13368106 for full phylogeny, including additional species. Specimen labels in orange represent the newly recorded haplotype in Spain. Sequences marked with an asterisk represent haplotypes collected in multiple countries: KU727026 in Vietnam and China, and KU727021 in Israel, South Africa and USA.
