The Ecosystem Ecology team investigates the landscape processes that influence the function and persistence of native ecosystems. Fire, drought, climate change, altered hydrological dynamics, weed invasion, fragmentation, urbanisation and altered fauna communities interact with plant traits in complex and powerful ways that can lead to change in the structure, composition, function and condition of ecosystems. Often these changes threaten the values that we attach to ecosystems. Our science aims to understand processes so that we can develop appropriate management responses that optimise conservation outcomes.
Ecosystem processes are the interactions between diverse ecological communities and the external and internal factors that drive dynamic processes within those communities. These interactions can be stabilising or disruptive, they can operate in synergistic or competitive, and diffuse or catastrophic ways. Their action can result in cyclical, chaotic, continuous or step-wise ecosystem change.
Global change processes – climate change, fragmentation, urbanisation, altered hydrological and fire regimes, failure of ecosystem function following from keystone species loss, soil degradation and the introduction of pest animal and plant species – further interact with these ecosystem processes, often to the detriment of the resilience and condition of ecosystems. Understanding how these processes function and interact leads to fascinating science but is also critical for the management of ecosystems for conservation, ecosystem services and risk abatement.
The Ecosystem Ecology currently focuses on three main areas: fire ecology, tree decline and ecosystem change, and plant-animal (pollination, dispersal, herbivory) interactions. The team works in urban bushlands, less disturbed 'intact' vegetation, and restoration sites. It employs tools from community ecology, population ecology, fire science, population genetics, seed science and ecophysiology – and collaborates closely with other sections of Kings Park Science, as well as researchers at UWA, Murdoch University and the Department of Parks and Wildlife.
