Introduction: What conservation problem or question does your study address?

An inventory of spider & its microhabitat utilization in ‘Biodiversity conservation management project’ by Kamakhya debuter in Guwahati metro, Assam, India. Study laid emphasis on the diversity of spiders and their potential as bio-indicators in the urban ecosystem. The present study investigated the species composition and diversity of spider species in the study area.

Methods: What were the main research methods you used?

Random samplings were carried out to search the spiders in different areas of the Nilachal hill protected by Kamakhya Debuter as ‘Biodiversity conservation management project’, Guwahati metro. The samplings were carried from January to April, 2014. The sampling method includes visual searching for the spiders as far distinct vision is possible. Photographs are taken of each species from different angles as much as possible. Active search and ground search were done under leaf litter, fallen or dry wood.

Results: What are your most important results?

During the study, 58 numbers of species were found in different microhabitat. Among them 32 species are identified belonging to 14 families and the others yet to be identified. 33 species were found in leaf litter, 12 species in the corners of the houses, 9 species between small plants or tree branches at human height, 3 species under rocks and 1 species in the river bank.

Discussion: What are your important discussion points and what is the relevance of your results to conservation (if any)?

Study concentrated mainly in the pre-monsoon season revealed a high number of spider species in the study area. A medium sized hillock like the Nilachal Hill consisting of such a wide variety of spider species reiterates the conservation importance of the study area. The study also recommends research institutions to take up spider research as it is a very neglected animal group.
