Red deer adult sex ratio: comparing three approaches using camera trap data

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
A naïve estimate of the adult sex ratio in red deer (Cervus elaphus) using raw camera trap data showed no bias when compared to more advanced statistical methods that account for detection probabilities or predict the sex of unknown sightings. Abstract European forests face severe challenges due to climate change, highlighting the importance of tree ...

Repellent Effects of Host Essential Oils and Limited Effects of Host Length on Tree‐Killing Bark Beetle Attacks

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 37-44, January 2026.
This study demonstrated that the host essential oil significantly reduced Polygraphus proximus Blandford (Coleoptera: Scolytinae) attack density, but the density did not differ significantly among logs of various lengths of Abies sachalinensis. Our study suggests that host essential oils can perform as repellents against conifer‐infesting bark beetles.
