Ten polymorphic microsatellite loci for the trematode Curtuteria australis (Echinostomatidae).
نویسندگان
چکیده
Ten polymorphic loci were isolated and characterised from the intertidal New Zealand trematode Curtuteria australis. This common parasite manipulates the burrowing behaviour of its abundant bivalve host Austrovenus stutchburyi, with cascading impacts on the biodiversity of intertidal communities. Observed heterozygosities of the 10 loci ranged from 0.500 to 0.905, and three to 14 alleles were detected in 24 trematode metacercariae. These loci are currently being used to investigate the molecular ecology of this species within its intermediate hosts.

Equal partnership: two trematode species, not one, manipulate the burrowing behaviour of the New Zealand cockle, <i>Austrovenus stutchburyi</i>
Metacercariae of the trematode Curtuteria australis (Echinostomatidae) accumulate in the foot of the New Zealand cockle Austrovenus stutchburyi, severely impairing the cockle’s ability to burrow under the sediments. This results in increased predation by birds on cockles, and thus enhanced transmission rates of the parasite to its bird definitive hosts. This host manipulation by the trematode i...

متن کاملThe parasite-induced surfacing behaviour in the cockle Austrovenus stutchburyi: a test of an alternative hypothesis and identification of potential mechanisms.
The New Zealand cockle Austrovenus stutchburyi, whose foot is commonly infected by the digenean trematode Curtuteria australis (Echinostomatidae), is often found heavily infected and unable to burrow on the sediment surface of tidal flats. This has been interpreted as a Curtuteria-manipulation with the purpose of increasing the transmission of the parasite to shorebirds acting as final hosts. U...

Samples of the New Zealand cockleAustrovenus stutchburyi (Veneridae) collected at two di¡erent intertidal levels were found to be heavily infected by the echinostome trematode Curtuteria australis which use the mud £at whelk Cominella glandiformis and shorebirds as ¢rst and de¢nitive host, respectively. Parasite loads were on average more than 2-fold higher at the high site than at the low site...
متن کاملContribution of parasites to intra- and inter-site variation in shell morphology of a marine gastropod
In gastropods, variation in shell morphology can be caused by the action of several biotic and abiotic factors. While much of this variation is seen in comparisons between different sites or populations, there is also substantial variation in shell morphology among individuals living side by side. We investigate the effect of trematode parasitism on both intraas well as inter-site variation in ...
