Cryptic speciation in two widespread subterranean amphipod genera reflects historical drainage patterns in an ancient landscape
The landscape of the Pilbara region of Western Australia has been relatively unchanged for 100 million years. The ancient river systems of this region might be expected to be sources of isolation andExpand

BIOGEOGRAPHY OF A WIDESPREAD FRESHWATER CRUSTACEAN: PSEUDOCONGRUENCE AND CRYPTIC ENDEMISM IN THE NORTH AMERICAN DAPHNIA LAEVIS COMPLEX
TLDR
We carried out a phylogeographic and population genetics study of one widespread crustacean group, the North American Daphnia laevis complex. Expand

Genome size variation in aphids
Abstract Genome sizes of invertebrates vary at least 1000-fold, with small genomes most common in species with rapid development. Although few groups have been studied, there is growing evidence thatExpand

Macrogeographic patterns of breeding system diversity in the Daphnia pulex group. I. Breeding systems of Canadian populations
Efforts to deduce the evolutionary significance of sexual reproduction from the taxonomic and ecological distributions of asexuals rely on the presumption that reversions of asexual taxa to sexualExpand

Macrogeographic patterns of breeding system diversity in the Daphnia pulex group from the United States and Mexico
Studies on the biogeographical patterning of reproductive systems promise to extend understanding of the factors which modulate breeding system transitions. Two closely allied cladoceran crustaceans,Expand

A TAXONOMIC REEVALUATION OF NORTH AMERICAN DAPHNIA (CRUSTACEA: CLADOCERA).III. THE D. CATAWBA COMPLEX
Despite the importance of Daphnia in freshwater zooplankton assemblages, species boundaries in the genus are unclear. This study verifies the taxonomic validity of D. catawba by establishing itsExpand

Chemical diversity in south-eastern Australian saline lakes II: biotic implications
This study explores how differences in ionic composition of south-eastern Australian saline lake waters, caused by path differentiation according to the Eugster–Jones–Hardie models of soluteExpand

Genetic variation in the onychophoran Plicatoperipatus jamaicensis
The Onychophora are a relic taxon which diverged early in the arthropod radiation and have shown little morphological differentiation for several hundred million years. Jamaica has the richestExpand

Genetic differentiation in Daphnia obtusa: a continental perspective
1. The restricted scale of most prior studies of genetic diversity in daphniid populations provides limited information on the geographical patterning of gene frequencies. The present study addressesExpand

Speciation in Darwin's darklings: taxonomy and evolution of Stomion beetles in the Galápagos Islands, Ecuador (Insecta: Coleoptera: Tenebrionidae)
Stomion is one of three speciose and taxonomically difficult genera of flightless Darwin's darkling beetles of the Galapagos Islands. The previously named species and subspecies of Stomion areExpand
