Abstract Farming systems of high natural and cultural value represent approximately 30% of farmlands in the European Union and are associated with a high species and habitat diversity and/or the presence of species of European conservation concern. This study aims to synthesize the existing knowledge on the assessment of biodiversity and ecosystem ...

The interaction between grass species and climatic season shapes the population dynamics of the cattle tick, Rhipicephalus microplus. This information highlights the potential of forage species to influence off‐host tick dynamics. Additionally, minimum temperature and minimum relative humidity were the most influential microclimatic predictors of ...

Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...
