Positive Selection of TLR2 and MyD88 Genes Provides Insights Into the Molecular Basis of Immunological Adaptation in Amphibians

open access: yesEcology and Evolution, Volume 14, Issue 12, December 2024.
We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...

Recognition of European mammals and birds in camera trap images using deep neural networks

open access: yesIET Computer Vision, Volume 18, Issue 8, Page 1162-1192, December 2024.
The authors present deep neural network models that can be used to recognise both mammal and bird species in camera trap images. This provides a novel tool to recognise bird species (including non‐vocal ones) in addition to mammal species with a single neural network, which supports researchers in analysing large amounts of camera trap data.

A forensic approach to understanding habitat use from stable isotope analysis of (avian) claw material [PDF]

open access: yes, 2003
1. The potential of using stable isotope signatures of avian claws in order to infer diet and habitat use was investigated. 2. Highly significant relationships observed between stable carbon and nitrogen isotope ratios (13C, 15N) in the claws and ...
