Assessing the distribution of elusive non‐game carnivores: are hunters valuable informants?

open access: yesThe Journal of Wildlife Management, Volume 87, Issue 4, May 2023., 2023
Our results show a high overall congruence but significantly different information provided by hunters and professionals on the distribution of the Egyptian mongoose, suggesting that both sources provide unique data for the management of non‐game species. Our findings stress the importance of engaging hunters in wildlife conservation, as they can share

Determinants of Crimean–Congo haemorrhagic fever virus exposure dynamics in Mediterranean environments

open access: yesTransboundary and Emerging Diseases, Volume 69, Issue 6, Page 3571-3581, November 2022., 2022
Abstract Crimean–Congo haemorrhagic fever (CCHF) is an emerging tick‐borne human disease in Spain. Understanding the spatiotemporal dynamics and exposure risk determinants of CCHF virus (CCHFV) in animal models is essential to predict the time and areas of highest transmission risk. With this goal, we designed a longitudinal survey of two wild ungulate
