Use of spiders (Araneae) as indicator for monitoring of habitat conditions in Tarai Conservation Area, India

The efficacy of spider as indicator of habitat conditions in Tarai Conservation Area was examined. To compare habitat specific spider communities, five vegetation types were sampled from March 2005 to August 2006 by using pitfall traps and other semi-quantitative collection methods along transects. Along with spider sampling 11 habitat variables …
