Tsang Pak Nok Toby

TPNTI'm a postdoctoral researcher at HKU. My research interests lie in community ecology and global change ecology. Specifically, my work aims to understand mechanisms determining species coexistence. Also, I apply ecological theories to examine how global changes affect biodiversity, such as urbanization, biological invasion and climate change. I use terrestrial insects as my study organisms primarily, given their high diverse and crucial roles in maintaining ecosystem functions. I've also worked on other taxa (e.g. birds) depending on the research question. Currently, I am interested in how land-use changes affect bee diversity globally.
