Molecular ecology of parasites: elucidating ecological and microevolutionary processes
We review studies that have used molecular markers to address ecological and microevolutionary processes in parasites. Our goal is to highlight areas of research that may be of particular interest in…
A comparison between mitochondrial DNA and the ribosomal internal transcribed regions in prospecting for cryptic species of platyhelminth parasites
Analysis of mitochondrial DNA loci and ribosomal DNA internal transcribed spacers for their use in prospecting for cryptic species of platyhelminth parasites shows a higher level of divergence among species relative to intra-specific variation.
LIFE CYCLES SHAPE PARASITE EVOLUTION: COMPARATIVE POPULATION GENETICS OF SALMON TREMATODES
Variation in life cycles can shape parasite evolution by predisposing them to vastly different genetic structures, and it is proposed that knowledge of parasite life cycles will help predict important evolutionary processes such as speciation, coevolution, and the spread of drug resistance.
Disentangling hybridization and host colonization in parasitic roundworms of humans and pigs

The results indicate that there is contemporary cross-transmission between populations of human and pig Ascaris and strong differentiation between populations was primarily driven by geography, with secondary differentiation resulting from host affiliation within locations.

The genetic linkage map presented here is a first for S. mansoni and the first for a species in the phylum Platyhelminthes, and furnishes a framework for comparative flatworm genomics and field-based molecular epidemiological studies.

A brief review of how co-structure studies in parasite systems can be used to address ecological, evolutionary, and epidemiological questions is provided.
An Infectious Topic in Reticulate Evolution: Introgression and Hybridization in Animal Parasites
This work focuses on what is known about how introgression and hybridization have influenced the evolution of protozoan and helminth parasites of animals and investigates the phenotype or fitness, and the epidemiological significance of hybrid parasites.
Effective sizes of macroparasite populations: a conceptual model.
This work uses a model of subdivided breeders to show how some basic demographic factors that control N(e) in all species could be estimated for macroparasites, and concludes that several features of parasite life cycles probably function in concert to reduce N( e) below that expected in a single free-living population of equivalent census size.
Microsatellite Markers for the Human Nematode Parasite Ascaris lumbricoides: Development and Assessment of Utility

35 microsatellite markers from the human parasitic nematode Ascaris lumbricoides are described and it is demonstrated that 26 autosomal loci can be scored reliably.
Development and specificity of Oochoristica javaensis (Eucestoda: Cyclophyllidea: Anoplocephalidae: Linstowiinae)
Experimental infections of native fence lizards and Indo-Pacific geckos demonstrated that the exotic tapeworm Oochoristica javaensis lacked host specificity, and lack of support for either assumption indicates a need for more rigorous analyses and experimentation to determine species of OochOristica.
