Biodiversity is declining globally, with agricultural expansion and intensification identified as major drivers of these losses. With demand for food increasing, as our population continues to grow, it is important to understand how biodiversity can be supported in agricultural systems, as biodiversity and the ecosystem services they provide are vital for continued agricultural production. During this PhD I will aim to improve understanding of the relationships between functional diversity, landscape complexity and land-use in agricultural systems across a range of taxa and spatial scales.
