Nolan James Rappa
Postdoctor at the department of Wildlife, Fish and Environmental Studies researching forest insect pollinator communities.


I am interested in (but not limited to) forest insect communities, and their roles in important ecosystem functions such as pollination and parasitism. I seek to assess the biodiversity focused management practices that can be incorporated into sustainable forest use, particularly by emulating natural processes and forest structures. My main research has focused on the influence of forest structure on habitat specialists, namely forest bees and wasps, but also beetle feeding guilds, and more recently, parasitic taxa. I am an Entomologist specializing in the order Hymenoptera (bees, ants and wasps), though I have been involved in projects looking at various taxa to gain a more comprehensive overview.
