Studies of morphological and molecular phylogenetic divergence in spiders (Araneae: Homalonychus) from the American southwest, including divergence along the Baja California Peninsula.
Comparative phylogenetic and phylogeographic analyses have revealed a pervasive midpeninsular divergence in the mitochondrial genealogies of numerous vertebrate taxa distributed on the Baja… Expand

Two waves of diversification in mammals and reptiles of Baja California revealed by hierarchical Bayesian analysis
Many species inhabiting the Peninsular Desert of Baja California demonstrate a phylogeographic break at the mid-peninsula, and previous researchers have attributed this shared pattern to a single… Expand

Patterns of habitat affinity and Austral/Holarctic parallelism in dictynoid spiders (Araneae:Entelegynae)
The ability to survive in a terrestrial environment was a major evolutionary hurdle for animals that, once passed, allowed the diversification of most arthropod and vertebrate lineages. Return to a… Expand

The spider family Selenopidae (Arachnida, Araneae) in Australasia and the Oriental Region
Abstract We relimit and revise the family Selenopidae to include four new genera and 27 new species from Australia and the Oriental Region. The family is redefined, as are the genera Anyphops Benoit,… Expand

A comparison of populations of island and adjacent mainland species of Caribbean Selenops (Araneae: Selenopidae) spiders.
The role of the landscape in structuring populations has been the focus of numerous studies, in particular, the extent to which islands provide opportunities for isolation, and the consistency of… Expand

The Arachnids of Hellshire Hills, Jamaica
The Hellshire Hills arguably contain the best example of old-growth dry forest remaining in the Caribbean. This area is home to many endemic and threatened species and unfortunately is also… Expand

Molecular systematics of Selenops spiders (Araneae: Selenopidae) from North and Central America: implications for Caribbean biogeography
The Caribbean region includes a geologically complex mix of islands, which have served as a backdrop for some significant studies of biogeography, mostly with vertebrates. Here, we use the… Expand

THE FEATURES OF CAPTURE THREADS AND ORB-WEBS PRODUCED BY UNFED CYCLOSA TURBINATA (ARANEAE: ARANEIDAE)
Abstract Orb-webs constructed by members of the spider family Araneidae are composed of sticky and non-sticky threads deposited in a stereotypic fashion. This study examines how changes in a spider's… Expand

A revision of the spider genus Selenops Latreille, 1819 (Arachnida, Araneae, Selenopidae) in North America, Central America and the Caribbean
Abstract The spider genus Selenops Latreille, 1819 occurs in both the Old World and New World tropics and subtropics and contains nearly half of the species in the family Selenopidae Simon, 1897. In… Expand

Assessment of rampant genitalic variation in the spider genus Homalonychus (Araneae, Homalonychidae)
. Animal genitalia are often complex and thought to vary little within species but differ between closely related species making them useful as primary characters in species diagnosis. Spiders are no… Expand
