TL;DR: Exploration of asymmetric rates of loss and gain in both a likelihood framework and using a Sankoff matrix under parsimony reveals that cribellum homology is supported when losses are two times more likely than gains.

TL;DR: In this paper, the authors present a comprehensive, cross-taxa overview of the soil biota of South Africa and discuss the literature and sampling methods used to assess soil biodiversity, available taxonomic expertise and main collections within South Africa, the availability of identification guides and online resources, and the status and distribution of described species.

TL;DR: Investigating the residual activity (repellency and toxicity) of selected pesticides on six principal species of spider occurring in an apple orchard concluded that spiders can recognise and avoid only fresh residues, although older residues might still be toxic to them.

TL;DR: Analysis of ecological data of the arboricolous nephilid spider Clitaetra irenae Kuntner 2006, endemic to Maputaland forests, South Africa, indicates the species' dependence on this highly threatened habitat, and argues for utilization of the ecology of arbor Nicolous nePhilid orb-weaving spiders (ClitaetRA and Herennia) in systematic conservation assessments in the Old World tropics.

TL;DR: In this article, the potential use of spiders as indicators of habitat changes was assessed in central Maputaland, South Africa, where three habitats, namely undisturbed sand forest, elephant disturbed sand forest and mixed woodland, were sampled.
