EKOLOGICAL-FAUNAL ANALYSES OF THE TREMATODES OF WATER-MARSH BIRDS OF THE TRANSBOUNDARY JANDAN LAKE

open access: yesЮг России: экология, развитие, 2014
In 2000-08 in the Jandar Lake, which is situated on the territories of Azerbaijan and Georgia, the author studied waterfowls of 23 species and found 35 species of trematodes. Trematode fauna was richer in birds with a wider range of food and bigger sizes,

Can the studies at a spatial scale of 100s meters detect the spatiotemporal fluctuations of a parasite assemblage? [PDF]

open access: yes, 2013
The importance of small-scale heterogeneity in local factors which overrides that of larger-scales factors, suggest that local factors play a major role in determining the richness and prevalence of larval digeneans in intertidal gastropods.

The effects of seasonality and parasitism on diet and habitat selection in the common periwinkle

open access: yesOikos, Volume 2026, Issue 4, April 2026.
The common periwinkle Littorina littorea is an ecologically important grazer, known for its strong influence on algal communities and its role in structuring ecosystems. It serves as the first intermediate host for several trematode species in the Baltic Sea, especially for the fluke Cryptocotyle lingua.

Scientists' Warning on the Rapid Evolution of Parasites in the Anthropocene

open access: yesEvolutionary Applications, Volume 19, Issue 4, April 2026.
ABSTRACT Human activities are changing the natural world at an accelerating pace, and as a consequence exerting novel and often strong selection pressures on living organisms. For species with traits conferring huge inherent evolutionary potential, like parasites, the outcome may be rapid adaptive responses spanning multiple phenotypic traits. The rise

Schistosoma Species and Hybrid Genotyping With a Field Deployable Multi‐Marker Amplicon Panel

open access: yesCurrent Protocols, Volume 6, Issue 3, March 2026.
Abstract Schistosomes are parasitic trematode worms of the genus Schistosoma, responsible for causing urogenital and intestinal schistosomiasis. Six primary species infect humans: S. mansoni, S. japonicum, S. mekongi, S. intercalatum, S. guineensis, and S. haematobium. In addition, several species including S. bovis, S. curassoni, and S.
