Research Overview and Current Projects

 

Much of my current research focuses on the transdisciplinary nature of contemporary conservation practice.  This draws on my background in conservation biology, protected area management, landscape and urban ecology, sustainable tourism and citizen science to address novel mechanisms for conservation action.

At the core of these activities research projects explore the interactions between species (typically vertebrates) and their socio-ecological environment.  I have an interest in threatened species where I conduct research that explores how these species persist and function across complex land-use mosaics.

 

I am a field ecologist at heart and have worked in diverse environments ranging from rainforests to semi-arid ecosystems in Australia and abroad (South Africa, Nepal, Tanzania, Botswana).  In a life before academia I spent nine years as an animal ecologist with the South African National Parks agency where I coordinated a national large mammal monitoring program and delivered on park planning and expansion initiatives. 

I am currently working on a number of urban ecology projects that address how birds respond to the thermal environment in urban green space as well as how bird community structure varies with urban development.  I have an ongoing long-term monitoring collaboration with a local community group to assess patterns in resource availability for the highly specialized Glossy Black-Cockatoo. 

 

I am also working on collaborative projects with colleagues in South Africa that explore the resilience in forest bird communities within fragmented landscapes. For specific details visit: https://experts.griffith.edu.au/8468-guy-castley

Research Supervision

I typically have a team of Honours and PhD students that I supervise at any one time. Prospective students are welcome to get in touch to discuss study options related to my key interests outlined above. Since joining Griffith in late in 2005 I have supervised 14 PhD / MPhil students and 19 Honours students (with the majority obtaining First Class Honours). I am currently supervising a further 8 PhD students.
