Phylogeny of the orb-web building spiders (Araneae, Orbiculariae: Deinopoidea, Araneoidea)
While the spinning complement of single pairs of glands does not change much over the evolution of the group, multiple sets of glands are dramatically reduced in number, implying that derived araneoids are incapable of spinning many silk fibers at the same time.
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 of…
Investigations into the phylogeny of the Lycosoid spiders and their kin (Arachnida: Araneae, Lycosoidea)
- C. Griswold
The phylogenetic relationships of spider families classically placed in the superfamily Lycosoidea, which possess a grate-shaped tapetum in some or all of the indirect eyes, are examined through exemplar taxa scored for 68 classical or newly elaborated characters.
Atlas of phylogenetic data for entelegyne spiders (Araneae: Araneomorphae: Entelegynae) with comments on their phylogeny
A phylogenetic analysis of higher groups of entelegyne spiders, with representatives of all enteleGYne families containing cribellate members and of Palpimanoidea, and a paraphyletic Araneoclada, excluding members of Haplogynae.
Spinneret Morphology and the Phylogeny of Haplogyne Spiders (Araneae, Araneomorphae)
Spider phylogenomics: untangling the Spider Tree of Life
Contrary to long held beliefs that the orb web is the crowning achievement of spider evolution, ancestral state reconstructions of web type support a phylogenetically ancient origin of the orbweb, and diversification analyses show that the mostly ground-dwelling, web-less RTA clade diversified faster than orb weavers.

This study compared a rapid and intense inventory of spiders from one hectare of a mature beech forest in Hestehaven, Denmark, comprising 8,710 adult spiders of 66 species to a previous, much more thorough, bi-weekly survey of two years duration from the same site that comprised 42,273 spiders (adult and juvenile) of 141 species.
Towards a Phylogeny of Entelegyne Spiders (Araneae, Araneomorphae, Entelegynae)
A phylogeny for all entelegyne families with cribellate members based on a matrix of 137 characters scored for 43 exemplar taxa and analyzed under parsimony confirms the monophyly of Neocribellatae, Araneoclada, Entelegynae, and Orbiculariae.

The symphytognathoid spiders of the Gaoligongshan, Yunnan, China (Araneae: Araneoidea): Systematics and diversity of micro-orbweavers
A ten-year inventory of the Gaoligongshan in western Yunnan Province, China, yielded more than 1000 adult spider specimens belonging to the symphytognathoid families Theridiosomatidae, Mysmenidae,…
