Automated identification of spotted‐fever tick vectors using convolutional neural networks

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)

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 ...

Spatial capture‐recapture can improve environmental impact assessments for large carnivores

Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.
Most Environmental Impact Assessments for large carnivores rely on summary statistics or relative abundance indices, all of which ignore imperfect detection and may lead to biased and unreliable conclusions about population status and infrastructure impacts. By applying spatial capture‐recapture (SCR) models to georeferenced genetic data from wolves in
