The Southern Hemisphere has traditionally been considered as having a fundamentally
vicariant history. The common trans-Pacific disjunctions are usually explained by the …

The Australian fauna is assessed for short-range endemism at the species level, ie the
prevalence of species with naturally small ranges of less than 10,000 km2. The …

Male structures specialized to contact females during sexual interactions often diverge
relatively rapidly over evolutionary time. Previous explanations for this pattern invoked …

The Peripatopsidae (Onychophora) are analysed by cladistic techniques. In all, 64 taxa,
including 41 new Australian species, are included, and 369 character states are studied for …

Currently, the number of valid species of Onychophora is uncertain. To facilitate taxonomic
work on this understudied animal group, we present an updated checklist for the two extant …

The Thoracica includes the ordinary barnacles found along the sea shore and is the most

Abstract The endemic South African velvet worm genus Peripatopsis currently contains eight

Low character variation among onychophoran species has been an obstacle for taxonomic
and phylogenetic studies in the past, however we have identified a number of new and …

A combination of single‐strand conformation polymorphism analysis (SSCP) and
sequencing were used to survey cytochrome oxidase I (COI) mitochondrial DNA (mtDNA) …
