Thesis Title
Resilience vs. decline: precipitation and atmospheric change drive contrasting responses in invertebrate communities
Research Project
Invertebrates form the foundation of terrestrial ecosystems, far outnumbering their vertebrate counterparts in terms of abundance, biomass and diversity. Often overlooked, these organisms contribute to structuring biological communities, through their roles in ecosystem functions like pollination and nutrient cycling. Changes in the composition of the Earth's atmosphere and climate, associated with emissions of carbon dioxide (CO2) and other greenhouse gases, have the potential to affect invertebrates and the ecosystems they underpin. Indeed, predicting the responses of species, and the communities they comprise, to global change is one of the great challenges facing modern ecology.
My project investigates the effects of predicted climatic and atmospheric change on invertebrate communities. Specifically, my projects use two of the Hawkesbury Institute for the Environment's flagship experimental platforms to look at the effects of elevated CO2 (EucFACE) and changes in precipitation patterns (DRI-GRASS) on invertebrate communities. The results of this work will contribute to understanding how intricate natural systems may respond to our changing climate.
