Research interests

• Use of aquatic assemblages to detect ecological change
• Spatial and temporal congruence of aquatic communities and the importance of ecological scale
• Effects of landscape position on aquatic community structure and function
• Structural, functional and energetic aspects of lake and stream communities
• Effects of climate on aquatic ecosystems; in particular, references and restoration endeavours
