Plant-disperser mutualistic networks

Understanding the role of hornbills in plant-disperser networks

This project aims to understand the relative importance of hornbills and other frugivores as seed dispersers for tree species across a gradient of seed sizes and fruit types using the network approach.

  • Hornbills are often driven locally extinct by high hunting pressures for their meat and other body parts!

  • Our understanding of the impacts of hornbill loss on plants is limited! A freshly shot Rufous-necked Hornbill.
