SUMMARY Host specificity is a fundamental component of a parasite's life history. However, accurate assessments of host specificity, and the factors influencing it, can be obscured by parasite cryptic species complexes. We surveyed two congeneric species of intertidal snail intermediate hosts, Zeacumantus subcarinatus and Zeacumantus lutulentus, throughout New Zealand to identify the number of genetically distinct echinostome trematodes infecting them and determine the levels of snail host… Expand
Molecular characterisation of four echinostomes (Digenea: Echinostomatidae) from birds in New Zealand, with descriptions of Echinostoma novaezealandense n. sp. and Echinoparyphium poulini n. sp.
Comparative morphological and phylogenetic analyses supported the distinct species status of Echinostoma novaezealandense n. Expand
Occurrence of Echinostomatoids (Platyhelminthes: Digenea) in Great Cormorant (Phalacrocorax carbo) and Grey Heron (Ardea cinerea): First Insights into the DNA Barcodes from Lake Victoria, Tanzania
Both morphology and molecular markers revealed the presence of three echinostomatoid species: Stephanoprora amurensis and Petasiger phalacrocoracis in P. carbo, and the Patagifer vioscai in A. cinerea, reported for the first time in African bird species. Expand
Estimates of coextinction risk: how anuran parasites respond to the extinction of their hosts.
This work estimates the extinction risk of helminth parasites of South America anurans by assuming parasite specificity and host vulnerability to extinction as determinants and considering host vulnerability in the model decreased the extinction probability of most parasites species. Expand
Acanthoparyphium shinanense n. sp. (Digenea: Echinostomatidae) from Experimental Chicks Infected with Metacercariae Encysted in Brackish Water Clams in the Republic of Korea
Acanthoparyphium shinanense was described from chicks experimentally infected with the metacercariae encysted in 2 brackish water clam species, Ruditapes philippinarum and Coecella chinensis, in the Republic of Korea, with low homology with A. spinulosum. Expand


Revealing the secret lives of cryptic species: Examining the phylogenetic relationships of echinostome parasites in North America.
The intra and interspecific variation detected in this study provides a genetic basis for seven species groups of echinostomes which will help accurately identify agents of disease as well as reveal cryptic aspects of trematode biology. Expand
Cryptic species complexes in manipulative echinostomatid trematodes: when two become six
SUMMARY Recent studies have shown that some digenean trematodes previously identified as single species due to the lack of distinguishing morphological characteristics actually consist of a number ofExpand
Host specificity and molecular phylogeny of larval Digenea isolated from New Zealand and Australian topshells (Gastropoda: Trochidae).
This study is the first to reveal cryptic species of digeneans in a single population of a molluscan first intermediate host and sheds light on the conditions that may favour switching among intermediate hosts inDigeneans, and on the presence/absence of host specificity in these parasites. Expand
Revealing Cryptic Parasite Diversity in a Definitive Host: Echinostomes in Muskrats
Molecular sequences provided a more accurate estimate of echinostome diversity in the muskrats and further support the idea that E. trivolvis is a species complex. Expand
Speciation of echinostomes: evidence for the existence of two sympatric sibling species in the complex Echinoparyphium recurvatum (von Linstow 1873) (Digenea: Echinostomatidae).
Two first intermediate host-specific sibling species of the 45 collar-spined echinostome Echinoparyphium recurvatum are presented, found to be morphologically indistinguishable in all major respects, yet they exhibited distinct biological characteristics. Expand
Parasites of polychaetes and their impact on host survival in Otago Harbour, New Zealand
It is found that there exists a great diversity of both trematodes and host–trematode associations within the polychaete fauna, whose ecological impact remains to be quantified. Expand
Cryptic diversity and patterns of host specificity in trematode flatworms
The widespread utilization of molecular markers has revealed that a broad spectrum of taxa contain sets of morphologically cryptic, but genetically distinct lineages ( Bickford et al. 2007 ). TheExpand
Evidence for gene flow in parasitic nematodes between two host species of shrews
Genetic discordance between parasite and host phylogenies suggests extensive gene flow among parasites across the host species boundary, and reciprocal monophyly for the shrew species is revealed, concordant with morphological diagnosis. Expand
DNA barcodes show cryptic diversity and a potential physiological basis for host specificity among Diplostomoidea (Platyhelminthes: Digenea) parasitizing freshwater fishes in the St. Lawrence River, Canada
Three lines of evidence indicate that physiological incompatibility between host and parasite is a more important determinant of host specificity than ecological separation of hosts and parasites in this important group of freshwater fish pathogens. Expand
Evolutionary relationships between trematodes and snails emphasizing schistosomes and paragonimids
This work investigates the types of evolutionary relationships between host and parasite, operating at different phylogenetic depths, that might explain current host specificity and distributions of both associates, and considers that phylogenetic tracking rather than an arms-race relationship might be a common alternative.
