A comparison of adhesive performance among six cursorial spider species

  A comparison of adhesive performance among six cursorial spider species Abstract The ability to adhere to surfaces is particularly relevant for cursorial predatory arthropods like hunting spiders, which often traverse relatively complex environments characterized by large variation in substrate properties. Here, we evaluated the adhesive performance of six hunting spider species that are common in eastern temperate North America and lack specialized tarsi for climbing smooth or inclined surfaces [Lycosidae: Pardosa lapidicina Emerton, 1885 and Rabidosa rabida (Walckenaer, 1837); Oxyopidae: Oxyopes salticus Hentz, 1845; Pisauridae: Pisaurina mira (Walckenaer, 1837); Dolomedidae: Dolomedes triton (Walckenaer, 1837), and Dolomedes scriptus Hentz, 1845]. We tested adhesion performance as shear load resistance (g) on a glass plate, and as the angle of failure (°) when the plate was gradually inclined relative to horizontal. Average angle of failure and shear resistance differed among ...

A trial study on the spider diversity (Araneae species) in Agartala City of West Tripura district in Tripura, India

Abstract

This study reported the diversity of spiders in Agartala city of West Tripura district in Tripura, India. A total of 9 families, 14 genera and 16 species were recorded. The most abundant family was found Araneidae (25%), followed by Salticidae (18.5%), Sparassidae and Nephilidae (12.5%), and Sicariidae, Pholcidae, Therididae, Tetragnathidae, and Thomisidae presented similar percentage of abundance (6.25%) in this study. This study exclusively reports for the first time the presence of the Sicariidae family in Tripura, along with morphological characters and behaviours, like web-building structure and activity time, were also analyzed for the spiders collected in this study.
