Range of Spiders (Arachnida Araneae) with a brand new report for India in and round Bidhannagar Faculty campus, Salt Lake: a part of a reclaimed city habitat
ABSTRACT
Spider range was recorded from the Bidhannagar Faculty campus and surrounding areas, a comparatively new habitat positioned in a densely populated Salt Lake metropolis close to Kolkata that was developed on reclaimed land from East Kolkata Wetlands (India). A complete of 35 species of spiders belonging to 26 genera and 13 households had been noticed. Probably the most vital discovering was the documentation of Pronophaea natalica (Simon, 1897), a species beforehand recognized solely from South Africa, which is now reported for the primary time from India. The household Salticidae emerged as probably the most various, comprising 10 species throughout 7 genera. This was adopted by Araneidae, represented by 6 species from 4 genera. The spider assemblage represents a spread of ecological guilds and behavioural methods, indicating a wholesome arthropod range on this city inexperienced area. The guild construction evaluation of the recorded spider assemblage revealed seven purposeful feeding guilds. Amongst these, stalkers had been probably the most dominant with 10 species, adopted by orb net weavers with 9 species, and ambushers and floor hunters with 5 species every. Much less represented guilds included foliage runners with 1 species, scattered line weavers with 2 species, and area net builders with 2 species. Timber and bush foliages had been probably the most most popular habitat for orb net weavers and stalkers. This discovering underscores the necessity for biodiversity monitoring and conservation in quickly urbanizing landscapes.
