Title of symposium:
Trophic interactions in human-modified tropical landscapes

Symposium Summary
Some of the most important mechanisms underpinning biodiversity involve trophic interactions, such as predation, parasitism, herbivory, and a range of mutualistic plant-animal interactions, including pollination and seed dispersal. Trophic interactions can regulate species abundance through changes in life history, can drive community assembly by determining coexistence and stability, and can affect ecosystem functioning by regulating ecosystem processes. Trophic interactions are also highly dependent on levels of biodiversity, and for this reason the strength and outcome of these interactions are strongly impacted in human modified landscapes. Recent methodological and technological advances are now allowing for a much greater assessment of food webs and trophic cascades, such that we are finally in the position of better understanding how trophic interactions affect and are affected by biodiversity changes, and ultimately how ecosystem functioning is impacted in modified habitats. In this symposium, we will bring together speakers using a range of methods, focusing on diverse set of taxa from different parts of the tropics to increase the knowledge of: (a) how trophic interactions are impacted by changes in biodiversity in modified landscapes; (b) how trophic interactions modify species abundance and community structure; and (c) how changes to trophic interactions could impact ecosystem functioning.
