About me

biodiversity
climate change refugia
conservation
environmental heterogeneity (habitat diversity)
dieback

Gunnar has a broad background in vegetation ecology, island biogeography and conservation biology. Most of his recent work focusses on drivers of diversity patterns. At the local scale (within meters) he investigates how environmental heterogeneity impacts microclimate and species distributions. On a regional scale, he studies the role of refugia in facilitating the persistence of biodiversity. Finally, he investigates the roles of climatic, biogeographic and topographic drivers in effecting patterns of biodiversity on large and global scales.

Gunnar's research group (https://biodiversityoceania.com/) focusses on four themes:

Refugia as safe havens for biodiversity under climate change
The dieback of stringybark forests in South... Read more

Teaching & student supervision

Highlights

I greatly enjoy teaching and have experience lecturing in the fields of plant biology, conservation, vegetation ecology, resource management and biogeography. I supervise several postgraduate and honours students:

Michael Otasowie Eguagie (PhD student, UniSA): Cyclone impacts on the functioning of rain forests.

Alivereti Naikatini (PhD student, Yniversity of the South Pacific): Behavioural ecology of Fijian birds.

Siteri Tikoca (PhD student, University of Adelaide): Microbats in Fiji.

Stephen Fricker (Masters student, UniSA): Seasonal variation of mosquito assemblages in the Murraylands.

Shaun O’Sullivan (Masters student, UniSA): Arthropod diversity in native and artificial vegetation remnants.

Nathan Blight (Honours student, UniSA): Bird behaviour along woodland edges.

Brandon Turner (Honours student, UniSA): Chytridiomycosis in South Australian frogs.

Donna Fitzgerald (Honours student, UniSA): Quantifying dieback of red stringybark in Spring Gully Conservation Park using remote sensing.

Natasha McMahon (Honours student, UniSA): Quantifying dieback of Alyxia buxifolia using remote sensing.
