摘要: Spiders were collected by sifting leaf litter of three common tree species, Cussonia paniculata sinuata, Olea europaea africana and Searsia lancea, in an undisturbed grassland habitat central South Africa. The study aimed to collect baseline data on spider assemblage structure, seasonality the effects structure assemblages. In total, 1385 spiders collected, representing 26 families 56 species. Four Obatala sp. (Amaurobiidae, 22.7%), Camillina maun Platnick & Murphy (Gnaphosidae, 17.0%), Proevippa (Lycosidae, 11.4%) Zelotes frenchi Tucker 9.2%) dominated fauna. Spider abundance was highest (n = 607), followed (n = 453) (n = 325). had greatest number species (41 spp.), (35 spp.) (30 spp.). Both richness per sample varied significantly between Of ten most abundant all but two showed a significant preference for particular types. Mean lowest litter, which deepest type, with interstitial space, whereas mean shallowest moderately compact structure. Resume Des araignees furent collectees en tamisant de la litiere feuilles trois especes d’arbres communes, et dans un prairies intact du centre l’Afrique Sud. L’etude visait recolter des donnees reference sur assemblages d’araignees, leur saisonnalite, les effets d’araignees. Au 1 385 ont ete collectees, representant familles especes. Quatre 22,7%), 17,0%), 11,4%) 9,2%) dominaient faune. L’abondance etait au maximum d’Olea suivi comptait le plus grand nombre d’especes par richesse echantillon variaient significativement entre d’arbres. Parmi dix abondantes, toutes sauf deux montraient une significative pour types particuliers. moyenne etaient faibles Cussonia, qui type profond mais avec d’espaces interstitiels, alors que l’abondance hautes d’Olea, est aussi mince dont moderement compacte.
