Seed and seedling ecology

Alpine daisy

Description

We have a long-standing interest in the seed and seedling ecology of Australian plants with an aim towards conseration and management under climate change. Work has focussed on Australian high country species, species of the Mediteranean-type ecosystem of WA, as well as grassland species: systems projected to be highly impacted by our changing climate. We investigate how climate change will affect the reproductive ecology and demography of Australian flora. We work closely with local seed banks and researchers therein.

Opportunities exist for projects for honours/MSC or PhD students in seed and seedling ecology. For more on this topic see these papers from lab members:
