The scientific interests of my research group are on a broad scale, but our research generally involves the study of animal responses to induced stress 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, behaviours and fitness measures and how this can scale up to directly and selectively 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 that are 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 new collaborative team led by Professor Barnes (NHM London) and myself looking at bee responses to a century of LUC has kicked-off, with Dr Andres Arce looking at trait evolution (with help from Masters student Marcus Rhodes) and a new NHM postdoc will be starting on the molecular analyses in January 2018.
I will be supervising Master students who will be visiting northern Sweden in Spring 2018 to initiate a international collaboration on phenological responses to climate change, supported by the Climate Impact Research Centre (CIRC) and led by Keith Larson.
Dr Kirsty Yule, Elspeth MacKellar, Jennifer Dawson and John Patterson have finished their fieldwork in the Maldives to looking at mosquito population and invertebrate community responses to pesticide applications in small island ecosystems. The results are currently being analysed as part of the SCIE:NCE project funded by Soneva resort and the Grantham Institute.
Masters student Jacob Birkenhead will be continuing the Maldives work.
The group welcomes Daniel Kenna who is starting his PhD on how bumblebee colony dynamics underpins responses to environmental change.
