Dr Rucha Karkarey
1) Animal behaviour, biodiversity and functioning
Through her Fellowship, Rucha will explore the processes that underlie species co-existence in highly diverse ecosystems and understand how they are impacted by global environmental change. Specifically, Rucha will focus on different mechanisms of competition between coral reef fish predators and will combine existing and new empirical data (observational and experimental) with advanced statistical modelling to determine how behavioural change could scale up to affect ecosystem level metrics. The project will highlight the role of inter-species interactions in enhancing biodiversity that may be critical to manage in order to buffer ecosystems against climate-change. Rucha’s work is based in the Lakshadweep Archipelago in India. She is also interested in developing research on biodiversity and functioning across the Chagos-Lakshadweep Oceanic ridge.
2) Community-led conservation practice
Rucha’s work on reef fish behaviours with the Nature Conservation Foundation (NCF, Mysuru) has informed a local community-led conservation initiative around fish spawning aggregations in the Lakshadweep. She aspires to continue working with local communities to co-develop research for the effective management of burgeoning reef fisheries in the Lakshadweep Archipelago.
