A halélősködő nyálkaspórások fejlődésének, kórtanának és fajlagosságának vizsgálata kísérletes és molekuláris biológiai módszerekkel = Studies on the development, pathogenicity and host specificity of fish myxosporeans by experimental and molecular biological methods [PDF]

, 2007
Balatonból, Kis-Balatonból, Dunából és Tiszából, valamint néhány tógazdaságból gyűjtött halon vizsgáltuk a nyálkaspórás fertőzöttség alakulását, és ugyanezen biotópokon tanulmányoztuk a nyálkaspórások oligochaeta férgekben élő actinospóra stádiumainak ...

Communities of metazoan parasites in seven sympatric skate species (Elasmobranchii, Rajidae) from the English Channel and Celtic Sea differing in conservation status

Journal of Fish Biology, Volume 105, Issue 3, Page 975-987, September 2024.
Abstract Elasmobranch populations are in steep decline mainly due to overfishing bycatch, but parasites may accelerate the collapse of vulnerable and/or highly parasitized species. We therefore studied metazoan parasites of Rajidae from the northeast Atlantic: vulnerable Leucoraja fullonica, near‐threatened Raja brachyura, Raja clavata, Raja ...

Investigation on parasitic infestation of Labeo rohita (Hamilton, 1822) in the south‐western region of Bangladesh

Veterinary Medicine and Science, Volume 10, Issue 4, July 2024.
Over the study, 180 L. rohita specimens were examined,, revealing the presence of six distinct parasite species, consisting of endoparasites. Through microscopic examination, a total of 323 parasites were investigated, categories including Cestode, Nematode, Acanthocephala, Trematode and Digenia, predominantly residing in the intestines and liver of L.

Scientific history, biogeography, and biological traits predict presence of cryptic or overlooked species

Biological Reviews, Volume 99, Issue 2, Page 546-561, April 2024.
ABSTRACT Genetic data show that many nominal species are composed of more than one biological species, and thus contain cryptic species in the broad sense (including overlooked species). When ignored, cryptic species generate confusion which, beyond biodiversity or vulnerability underestimation, blurs our understanding of ecological and evolutionary ...
