Animal movements contribute to the spread of infectious diseases and are driven in part by environmental conditions. We investigated the links among the environment, animal movement, and infectious disease dynamics in waterfowl, which are among the primary wildlife hosts of avian influenza viruses. By combining telemetry data on 4606 individuals from 26 waterfowl species with data on land cover, weather, and vegetation, we found that waterfowl moved less in areas of higher land cover heterogeneity and higher human population density. Moreover, predicted waterfowl movement distances were weakly but positively correlated with distances between detections of H5N1 highly pathogenic avian influenza in wild waterfowl, suggesting that environmental conditions might contribute to the spread of this disease via their effects on bird movements. By considering wildlife movements alongside other drivers of infectious disease dynamics, such as livestock production and human mobility, we move closer to predicting outbreaks and informing interventions.

A DGAV publica o Relatório de Controlo de Resíduos de Pesticidas em produtos de Origem Vegetal correspondente a 2024, produzido no contexto das atividades oficiais de controlo visando garantir um elevado nível de proteção da saúde pública e a conformidade com os requisitos de segurança alimentar estabelecidos.

Publicação técnica dedicada ao controlo da acácia-austrália (Acacia melanoxylon) em áreas de pinhal-bravo, um recurso dirigido a técnicos, proprietários e gestores florestais. O documento reúne orientações práticas atualizadas para apoiar intervenções mais eficazes e sustentáveis no terreno.
