Estimating terrestrial biodiversity through extrapolation.
Both the magnitude and the urgency of the task of assessing global biodiversity require that we make the most of what we know through the use of estimation and extrapolation. Likewise, futureExpand

Systematics and Evolution of Spiders (Araneae)
In the last 15 years understanding of the higher systematics of Araneae has changed greatly. Large classical superfamilies and families have turned out to be polyor paraphyletic; positedExpand

Phylogeny of the orb-web building spiders (Araneae, Orbiculariae: Deinopoidea, Araneoidea)
Abstract This phylogenetic analysis of 31 exemplar taxa treats the 12 families of Araneoidea (Anapidae, Araneidae, Cyatholipidae, Linyphiidae, Mysmenidae, Nesticidae, Pimoidae, Symphytognathidae,Expand

Undersampling bias: the null hypothesis for singleton species in tropical arthropod surveys.
1. Frequency of singletons - species represented by single individuals - is anomalously high in most large tropical arthropod surveys (average, 32%). 2. We sampled 5965 adult spiders of 352 speciesExpand

Designing and Testing Sampling Protocols to Estimate Biodiversity in Tropical Ecosystems
Sampling methods to estimate total species richness of a defined area (conservation unit, national park, field station, "community") will play an important role in research on the global loss ofExpand

A phylogenetic analysis of the orb-weaving spider family Araneidae (Arachnida, Araneae)
We present the first cladistic analysis focused at the tribal and subfamily level of the orb-weaving spider family Araneidae. The data matrix of 82 characters scored for 57 araneid genera of 6Expand

The functional significance of silk decorations of orb‐web spiders: a critical review of the empirical evidence
A number of taxonomically diverse species of araneoid spiders adorn their orb‐webs with conspicuous silk structures, called decorations or stabilimenta. The function of these decorations remainsExpand

THE ANT FAUNA OF A TROPICAL RAIN FOREST: ESTIMATING SPECIES RICHNESS THREE DIFFERENT WAYS
Species richness is an important characteristic of ecological communities, but it is difficult to quantify. We report here a thorough inventory of a tropical rain forest ant fauna and use it toExpand

The Monophyletic Origin of the Orb Web
TWO VENERABLE groups of spiders spin orb webs: the cnbellate Ulobondae, weavers of calamistrated sticky silk, and the ecribellate Araneidae, weavers of true viscid silk (Figs. 12.2, 12.1).Expand
