Research Interests

Please find my research group website on insect ecology & evolution here:

The scientific interests of my research group are on a broad scale, but our research generally involves the study of animal responses to environmental stressors to address ecologically applied issues, as well as taking an evolutionary biology approach to understanding trends in ecology. 

In particular we are interested in how anthropogenic influences, primarily land-use change and associated activities, affect animal populations and biodiversity. This has involved focusing on how specific factors, such as aspects of habitat loss or chemical applications associated with agricultural practices, can influence individual physiology, behaviour(s) and fitness measures and how this can scale up to shape populations and communities.

Terrestrial invertebrates have been the group used to address our questions, and whilst not wedded to a particular study organism/system, social insects have been the focus of much of our research. Their large and intricate societies exhibit efficient and often complex cooperative behaviours making them not only interesting for the study of animal behaviour, but also a dominant insect group in the environment that provide vital ecosystem functions and crucial ecosystem services important for human welfare.

Here is a short video introducing one of the topics that we are interested in studying - threats to insect pollinators:

The third season of our Arctic bumblebee project will be starting in May. The project welcomes Michael Tansley, Sebastian Pipins and Alan Ward 

Rich Gill has been involved in a recent National Geographic funded project getting schools involved in insect pollinator surveys.
