Harvestmen: the biology of Opiliones

This monograph discusses the phylogeny and biogeography of harvestmen, a small group of animals that lived in what is now Europe more than 3,000 years ago and the role they played in the evolution of humankind.

Systematic review of the neotropical family stygnidae: (opiliones, laniatores, gonyleptoidea)

A new classification is herein proposed based on a cladistic analysis using 35 terminals and 50 characters of external morphology and male genitalia that forms the basis of the supraspecific classification of Stygnidae.

Phylogeny of harvestmen family Gonyleptidae inferred from a multilocus approach (Arachnida: Opiliones)

The traditional use of a small set of morphological characters in the systematics of Gonyleptidae is unable to explain the complex evolution of the family.

Complex meiotic configuration of the holocentric chromosomes: the intriguing case of the scorpion Tityus bahiensis

Female prophase I cells revealed multivalent chromosome associations and/or unsynapsed or distinctly associated chromosome regions (gaps, less-condensed chromatin, or loop-like structure) that were continuous with synapsed chromosome segments, and data permitted us to suggest that the chromosomal rearrangements of T. bahiensis occurred in a heterozygous state.
