Research

Our researchers and students work on an inter-disciplinary line but concentrate on four major themes of Biodiversity Conservation, Climate Change, Human Ecology and Environmental Governance by undertaking field, laboratory and modeling studies. Our location in peninsular India means that much of CRGCS’ research is focused on the impacts of global change on the climate, biota and ecosystems of the Western Ghats Biodiversity Hotspot.


Research Clusters

Biodiversity Conservation

Terrestrial Ecology
Group Leaders: Anitha K and Joyce Joseph
The Terrestrial Ecology group is interested in population assessments and behavioural ecology of large mammals, floristic characterization, and carbon assimilation capacity of plant communities, diversity and taxonomy of lizards and snakes in Myristica swamps and Shola forests. Previous work has focused on characterization and population dynamics of vegetation communities in human altered landscapes.

Human Animal Conflicts
Group Leader: Rohit Singh
The group is mainly interested in understanding the patterns of human-animal conflicts and developing effective co-management strategies. Current research focus is on Elephants, Sloth Bears (Kerala region of Western Ghats) and Brown Bear (Western Himalayas).

Aquatic Ecology and Conservation
Group Leaders: Benno Pereira, Anvar Ali and K. Krishnakumar

Researchers of the Aquatic Ecology and Conservation group works on freshwater (streams of the Western Ghats), brackishwater (Vembanad Lake) and marine (Arabian Sea) ecosystems addressing the issues in distribution, ecology and conservation of fin-fishes. Additional areas of research are conservation aquaculture, reef fisheries, coral reef ecology and marine invertebrates. Most recently, the group has started to work on invasive alien species (IAS) and their impacts on native fish species in Kerala.

Systematic Conservation Planning
Group Leader: Shijo Joseph
Systematic Conservation Planning group is the most recent of the nine research groups to be established in CRGCS. This group is interested in identifying priority areas for conservation in freshwaters using the principles of systematic conservation planning.

GIS and Remote Sensing
Group Leader: Shijo Joseph
The group has state of art knowledge in applying geospatial tools in natural resources management. The major thrust areas involve Ecosystem Dynamics, Hyperspectral Remote Sensing, field spectroscopy, atmospheric correction, radiosity modelling, Species distribution modelling and Predictive land cover modeling, and spatial multi-criteria decision analysis.

Evolutionary Genetics and Biogeography
Group Leaders: Siby Philip and Anvar Ali
The Evolutionary genetics and Biogeography group at CRGCS is primarily interested in understanding organismal evolution of aquatic and terrestrial taxa in the Western Ghats Hotspot. Current research focus is on freshwater fishes. Researchers in the group are currently collating baseline information on phylogeography of freshwater fishes. Apart from throwing light on the biogeographic history of the Western Ghats, research at this group will help solve some long standing taxonomic problems. The research is hence interdisciplinary and members work with the ecology, GIS and conservation planning groups at the center. The ultimate aim of the group’s research is to provide baseline information that will help comprehend the biology of various groups of organisms in the Western Ghats and facilitate improved conservation.


Climate Change

Climate Change Simulation
Group Leader: Shijo Joseph
The group is interested in understanding the physical basis of climate change, impacts of climate change on ecosystems and human welfare, and adaptive management strategies to be evolved in response to climate change impacts. The thrust area involves carbon, water and energy fluxes and its modelling, Dynamic Global Vegetation Modelling, Earth Observation Science Algorithms, Calibration and Validation of EO Data, and Sensitivity, uncertainty and error propagation in climate models.

Human Ecology

Natural Resource Management and Livelihoods
Group Leader: Rajeev Raghavan
The group is interested in understanding the interactions between natural resource use, conservation and livelihoods. Major focus is on the exploitation of threatened food and ornamental fishes and their impacts on conservation and fisher livelihoods. More


Environmental Governance

Environmental Governance, Law and Policy
Group Leader: Lavanchawee Sujarittanonta
The group is interested in development of policies relevant to environmental conservation and natural resource management. Current focus is on issues related to biopiracy and trade in threatened species from the Western Ghats.
