Abstract

Olive groves are one of the most important savannah-like agroecosystems in the world. Understanding how anthropogenic actions at different scales can affect biodiversity and ecosystem services in this agroforest is a challenge for human society. In this doctoral thesis, we study, for the first time at the regional scale, how agricultural management and landscape complexity affect both independently and jointly, the diversity and ecosystem services provided by: solitary bees, ants, and insectivorous birds in Andalusian olive groves. Results show that local management effects are more important than landscape ones in this system. Specifically, maintaining herbaceous cover and promoting organic management benefits the three studied groups. However, some of these effects were moderated by landscape complexity, being environmentally friendly measures more effective in landscapes of intermediate complexity. Therefore, implementing measures to increase landscape complexity in simple landscapes (e.g., more semi-natural patches) should increase the effectiveness of local agri-environmental measures.
