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 ...

Parasite induced changes in neuronal activity : is the parasitic eye-fluke (Diplostomum spp.) manipulating its Arctic charr (Salvelinus alpinus) host?

, 2022
Many parasites possess complex lifecycles and depend on several host species to complete their lifecycle. Some parasites even manipulate their hosts phenotype in a way that facilitates trophic transmission to their final host (i.e., parasite-induced trophic transmission; PITT) in order to complete their life cycle.

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.

Relationship between Water Quality Parameters and Parasite Infestation in Farmed Oreochromis niloticus in Selected Rift Valley Counties, Kenya

Aquaculture Research, Volume 2024, Issue 1, 2024.
Globally, parasitic infections hinder aquaculture productivity and sustainability. Improper water quality parameters reduce fish immunity, make them susceptible to parasites, and enhance parasitic proliferation in culture systems. Subsequently, this study aimed to determine the prevalence and intensity of ecto‐ and endo‐parasite infesting Oreochromis ...

Salinity dependence of parasite infestation in the European eel Anguilla anguilla in northern Germany [PDF]

, 2009
The aim of the study was to examine metazoan parasite communities of European eels (Anguilla anguilla) in fresh-water, brackish water and marine localities in northern Germany. In all, 29 parasite species/taxa were found in 170 eels: eight digeneans, one

Description of a new actinosporean type from South African freshwater [PDF]

, 2004
The 1st report on actinospores described these organisms as parasites related to myxosporeans. For a long time this group of parasites was believed to represent an independent taxonomic entity.
