Helminth infracommunities of a population of the Gran Canaria giant lizard Gallotia stehlini
Journal of Helminthology, 2004AbstractA survey of gastro-intestinal helminth communities of Gallotia stehlini (Sauria: Lacertidae) from Gran Canaria island (Canary Archipelago, Spain), was conducted to determine the prevalence, abundance and species diversity of intestinal parasites in these lizards.

AbstractThe structure and composition of parasite communities of Mullus argentinae were analysed under two alternative hypotheses in a sample of 75 specimens caught off Mar del Plata, Argentina (38°27′S, 57°90′W). The first, based on the dominance of trophically transmitted larval parasites of low host-specificity among fish species in the region ...

A total of 76 adult individuals of Rana vaillanti were collected in Laguna Escondida, Los Tuxtlas, Veracruz, Mexico, and their helminth infracommunity structure was determined. Among the 21 helminth taxa collected (10 digeneans, 8 nematodes, and 3 acanthocephalans), the digenean Langeronia macrocirra reached the highest prevalence (64.4%), mean ...

Abstract Parasites were harvested from lungs and gastrointestinal tracts of Alligator mississippiensis from Texas. We compared our results with previous parasitism findings from alligators harvested in 2011 in Louisiana and Florida. Florida alligators exhibited the greatest pentastomid prevalence and mean intensity and illustrated higher stomach ...

The study aims to characterise and compare the helminth assemblages and helminth infracommunities in the marsh frog, Pelophylax ridibundus and the edible frog, P. esculentus collected in the northern part of Ukraine.Occurrence and abundance of the helminths were analysed by calculating the prevalence, intensity, and mean abundance of infection ...

Within populations the contact rate of hosts and infectious parasites is mediated by the interactions of resource availability, host density, and host behavior. Fluctuations in host density can result in the loss or extinction of a parasite population as contact rates between parasites and susceptible individuals drop below thresholds of parasite ...

The literature on biotic and abiotic factors affecting transmission, survival and reproduction of helminths in domestic animals and humans, and on helminth surveys of wild mammals, are legion. However, of the examples cited in the review on communities of parasites by Holmes and Price (1986), few are drawn from studies on the helminths of mammals. This

Four species assemblages of desmognathine salamanders are sympatric in and along many mountain streams of the southern Appalachians. The species, Leurognathus marmorata, Desmognathus quadramaculatus, D. monticola and D. ochrophaeus, span an aquatic to terrestrial habitat continuum ranging from totally aquatic (L. marmorata) to primarily terrestrial (D.
