Dr Jenni Stockan is a Research Scientist within the Ecological Sciences Group. Jenni has over eighteen years research experience particularly within the field of insect ecology.

Invertebrates are integral to almost all ecosystems contributing to key processes such as nutrient cycling, natural pest control, pollination of crops and wildflowers and as a food source for other organisms. Jenni is interested in how key stressors such as climate change, land management, plant diseases and invasive species affect invertebrate abundance and assemblages and the impact this has on ecosystem services. Jenni currently coordinates the Biodiversity and Ecosystems for the Scottish Government Strategic Research Programme.

The James Hutton Research Institute is the result of the merger in April 2011 of MLURI and SCRI. This merger formed a new powerhouse for research into food, land use, and climate change.
