Ecological divergence of closely related Diplostomum (Trematoda) parasites

Parasitology, 2006
Parasite life-cycles present intriguing model systems to study divergence in resource use and ecology between parasite taxa. In ecologically similar taxa, consistent selective forces may lead to convergence of life-history traits, but resource overlap and similarity of life-cycles may also promote divergence between the taxa in (1) use of host species ...

Effects of water quality on fish parasite biodiversity and physiological responses in the host fish Clarias gariepinus from a eutrophic lake subjected to acid mine drainage in South Africa

Integrated Environmental Assessment and Management, Volume 20, Issue 5, Page 1539-1553, September 2024.
Abstract Elevated concentrations of contaminants have negative impacts on aquatic organisms and their parasites. Changes in parasite infections have been proposed as a technique for monitoring the health of aquatic ecosystems. Furthermore, alterations in physiological responses (biomarkers) of organisms have also been used to delineate ecosystem ...

High levels of metacercarial infestation (family: Diplostomidae) do not affect host energetics and swimming performance in the Epaulette goby (Coryogalops sordidus, Gobiidae)

Journal of Fish Biology, Volume 104, Issue 4, Page 1165-1179, April 2024.
Abstract Parasites have deleterious effects on their hosts, often resulting in altered host behavior or increased energy expenditure. When organisms are exposed to suboptimal environments, parasite loading may increase. Microbialite pools along the warm temperate South African coastline have been hypothesized as refugia for Epaulette gobies ...

Studies on the morphology and life-cycle ofDiplostomum (Diplostomum) gasterostei(Strigeida: Trematoda)

Parasitology, 1966
One of a large number ofLymnaea peregra(Mull.) from a pond near Glasgow was found to be infested withCercaria diplostomi gasterostei.C. d. gastrosteihas been found to penetrateGasterosteus aculeatusand develop into a diplostomulum in the retina of the eyes.Large numbers ofG.

Environmental correlates of adaptive diversification in postglacial freshwater fishes

Journal of Fish Biology, Volume 104, Issue 3, Page 517-535, March 2024.
Abstract Determining how environmental conditions contribute to divergence among populations and drive speciation is fundamental to resolving mechanisms and understanding outcomes in evolutionary biology. Postglacial freshwater fish species in the Northern Hemisphere are ideal biological systems to explore the effects of environment on diversification ...

Diplostomum cf. vanelli Yamaguti, 1935 (Trematoda: Diplostomidae Poirier, 1886): Morpho-Molecular Data and Life Cycle

Diversity
Furcocercariae, of the trematodes from the family Diplostomidae, were found in freshwater snails—Radix auricularia, which were collected in a reservoir located on Popov Island (Peter the Great Bay, Sea of Japan).

Fitness effects of assisted gene flow in an endangered salmonid population

Conservation Science and Practice, Volume 6, Issue 1, January 2024.
This study investigates the impact of assisted gene flow on the fitness of an endangered landlocked salmon population. Our results reveal that while assisted gene flow can have a positive influence on individual growth, it can also lead to decreased survival rates under predation risk.

Freshwater fish as hosts for parasites in Australia: How much do we really know?

Ecology of Freshwater Fish, Volume 33, Issue 1, January 2024.
Abstract Australia has a highly endemic freshwater fish fauna, but basic biological knowledge for most is lacking. This includes an understanding, and description, of their parasite fauna. Additionally, the impacts of introduced fish species, and their parasites which have transferred across to native species, are also mostly unknown.
