Molecular methods are becoming increasingly important in systematic acarology. In this
review I describe the properties of the ideal molecular marker and compare these with …

The application of molecular markers to the study of ticks and mites has recently yielded new
insights into their population structures and taxonomic relationships. Ticks have been …

Many arthropods with restricted diets rely on symbiotic associations for full nutrition and
fecundity. Tsetse flies (Diptera: Glossinidae) harbor three symbiotic organisms in addition to …

Background Amblyomma cajennense F. is one of the best known and studied ticks in the
New World because of its very wide distribution, its economical importance as pest of …

Polymerase chain reaction amplification of the intergenic spacer region between the 5S and
18S genes from Meloidogyne chitwoodi, M. fallax, and M. hapla enabled these three …

Cladistic analysis of a numerical data matrix describing 27 characters for species of Taenia
resulted in 4 most parsimonious phylogenetic trees (174 steps; consistency index= 0.28; …

Systematics involves resolving both the taxonomy and phylogenetic placement of
organisms. We review the advantages and disadvantages of the two kinds of information …

Abstract Background The rock cavy Kerodon rupestris (Wied-Neuwied, 1820) is a rodent
species endemic to northeastern Brazil. Earlier studies have associated the argasid tick …

The role of natural hybridization and introgression as part of the evolutionary process is of
increasing interest to zoologists, particularly as more examples of gene exchange among …

There has been much progress in our understanding of the phylogeny and evolution of ticks,
particularly hard ticks, in the past 5 years. Indeed, a consensus about the phylogeny of the …
