Abstract |
A survey of spider community composition and diversity associated with foliage of two ornamental plants (Lantana shrubs and Croton trees) was carried out in the Orman garden. Foliage beating, hand collecting and sweep nets were used. Numbers of collected spiders were pooled and analysed for species diversity using Shannon-Wiener Index, evenness, Simpson Index and Sørensen Quotient of Similarity.
A total of 567 spiders grouped in 13 families belonging to 34 genera and more than 34 species. Vegetation type influenced spider abundance. Lantana shrubs received 263 individuals belonged to 25 genera, 27 species of 13 families, while Croton trees received 304 individuals belonged to 21 genera, 22 species of 10 families.
Five families contained 85.17% of the total collected spiders; they are Miturgidae, Philodromidae, Salticidae, Theridiidae and Araneidae. Miturgidae was the most abundant family (20.1%) followed by Philodromidae (19.75%), Salticidae (18.3%), Theridiidae (14.6%) and Araneidae (12.3%). The other remaining families represented 14.6% of the total catch.
Guild structure analysis revealed seven feeding guilds namely, stalker, ground runner, foliage runner, ambusher, orb web spiders, space weaver and wandering sheet spiders. Guild structure varied considerably in relation to the structural quality of vegetation; the foliage runner, stalker and ambusher spider guilds were the dominant feeding guilds on Lantana representing 14.5, 12.3 & 11.5%, respectively of the total collected spiders, while the orb web spiders, the space weavers and the ambushers were the dominant feeding guilds on Croton representing 13.8, 12.8 and 12.7, respectively.
