Our work is primarily question-based, rather than organism-based, and current study systems include

  • Insects (primarily butterflies and bees)
  • Social spiders (Stegodyphus sarasinorum)
  • Plants
  • Reptiles

We also work on questions at the level of landscape/community:

  • Myristica swamps
  • Rocky plateaus of Northern Western Ghats
  • Deciduous forests in Bhimashanker

 

Ongoing research projects

The Vanasiri and BEE group websites have more detailed information on respective research projects. Below is a sample of ongoing projects

RESEARCH FACILITIES

ICREEE has excellent facilities for many kinds of ecological and evolutionary research projects. We have several growth chambers for controlled-environment experiments, outdoor nethouse facilities for rearing insects & experiments, rooms for indoor experiments, molecular labs for genotyping work, a microscopy unit, high-speed videography equipment, etc. We also have nethouses and large outdoor enclosures for experiments. The campus is located at Vithura, ca. 45 km from Thiruvananthapuram, the capital of the state of Kerala. This mountainous, rainforested region in the southern India is part of the Western Ghats and Sri Lanka biodiversity hotspot, with high diversity and endemism. The campus of about 200 acres includes substantial streches of semi-evergreen, mixed-deciduous and riparian jungle. The reserved forest adjoining our campus is contiguous with one of the best tracts of primary rainforest in India – the Agasthyamala Biosphere Reserve, which includes the Peppara, Neyyara & Shendurney Wildlife Sanctuaries, as well as the Kalakkad-Mundanthurai Tiger Reserve. The campus therefore serves as a splendid laboratory for field-based experiments. Moreover, the rich biodiversity within and around the campus provides many model systems for experimental work.

Here are some images from the IISER Thiruvananthapuram campus
