TLDR
The large, dominant heteropodid, Leucorchestris, may determine many characteristics of the Namib arthropod community, including large size, polyphagy, low metabolism, longevity, brood care and seasonal foraging and breeding patterns.About:

An estimated 400-800 million tons of prey are annually killed by the global spider community.
TL;DR: The presented estimates of the global annual prey kill and the relative contribution of spider predation in different biomes improve the general understanding of spider ecology and provide a first assessment of theglobal impact of this very important predator group.

Trophic specialisation in a predatory group: the case of prey-specialised spiders (Araneae).
Stanislav Pekár,Soeren Toft +1 more
TL;DR: This work critically evaluates contemporary evolutionary hypotheses that might be used to explain the evolution of specialised foraging in predators, and proposes a unifying concept within which four types of trophic categories are defined using ecological (diet breadth) and evolutionary contexts.
Journal ArticleDOI
Evolution of stenophagy in spiders (Araneae): evidence based on the comparative analysis of spider diets.
TL;DR: The evolution of stenophagy in spiders appears to be complex and governed by phylogeny as well as by ecological determinants.
Journal ArticleDOI
Vibration Sensitivity and a Computational Theory for Prey-Localizing Behavior in Sand Scorpions
TL;DR: A computational theory to account for wave source localization has been developed using a population of second-order neurons, each receiving excitatory input from one vibration receptor and inhibition from the triad of receptors opposite to it in the eight-element array, confirming a simple theory for computational mapping of surface vibration space.

Spiders in Ecological Webs
TL;DR: The spider in the ecological play is a central character in the story of how spiders avoid competition and the impact of spiders on insect populations and competitionist views of spider communities are examined.
Climate of the central Namib Desert
TL;DR: In this paper, data from eight meteorological stations in the centraI Namib Desert have been summarised for the period 1976 to 1981, and a brief description of the climate of the region and examples of some typical weather conditions are presented.
