Automated identification of spotted‐fever tick vectors using convolutional neural networks [PDF]
Medical and Veterinary Entomology, Volume 39, Issue 4, Page 829-841, December 2025.We evaluate the performance of convolutional neural networks (CNN) AlexNet, ResNet‐50 and MobileNetV2 for the automated identification of tick species capable of transmitting spotted fever. CNNs achieved accuracy rates of ~90% in identifying ticks and showed sensitivities of 59%–100% according to species, sex, position or image resolution.

Host–parasite relationship in urban environments: A network analysis of haemoparasite infections in Nasua nasua Linnaeus (South American coati) [PDF]
Medical and Veterinary Entomology, Volume 39, Issue 3, Page 456-463, September 2025.Urban environments alter host–parasite dynamics, as seen in Nasua nasua, where haemotropic Mycoplasma plays a key role in parasite spread through frequent social interactions. Network analysis revealed low modularity in interactions between N. nasua and tick‐borne haemoparasites, with functional roles unaffected by biotic factors, tick infestation or ...

Temporal and spatial patterns in the shifting of otter diet to invasive prey after river damming
River Research and Applications, Volume 38, Issue 8, Page 1450-1459, October 2022., 2022 Abstract River damming promotes profound changes in aquatic biodiversity, including the facilitation of biological invasions, with subsequent impacts on native communities. The Eurasian otter (Lutra lutra) is a generalist aquatic predator that often incorporates new prey types when they become available.

Journal of Applied Ecology, Volume 59, Issue 6, Page 1496-1512, June 2022., 2022 We identify the areas of Europe and North Africa that are most sensitive for the specific populations of birds for which sufficient GPS tracking data at high spatial resolution were available. We also map vulnerability hotspots where mitigation at existing EI should be prioritised to reduce collision risks.

Ecological Solutions and Evidence, Volume 3, Issue 1, January–March 2022., 2022 While for many large carnivores population density is often estimated through spatially explicit capture‐recapture (SECR) applied to camera trap data, the lack of pelage patterns in lions has limited the application of this technique to the species. Here, we show that by using xenon‐flash camera traps, combined with consistent framing and angles of ...
