Research interests

The physiology, behaviour and ecology of arthropods and how integrating among these fields can be used to gain a functional understanding of food webs and community dynamics in nature. I am particularly interested in carnivorous arthropods and much of my research examines spiders.

My work at the University of Sydney focuses on the integrative nutritional ecology of carnivorous arthropods. A major long-term goal of this work is to understand:

1) the specific nutritional requirements of carnivores,

2) how those physiological requirements influence the foraging behaviour of carnivores (e.g., prey choice, nutrient extraction) and

3) the consequences of carnivore foraging behaviour for community and ecosystem dynamics.

An overview of some of these ideas can be found in Wilder (2011). In addition to integrating among fields, I also try to integrate both laboratory and field work to gain a rigorous understanding of how nutrition influences carnivore performance and behaviour (laboratory studies) and the relevance of these laboratory findings for populations in the field (field surveys and experiments).
