OBJECTIVE The aim of this study was identification of the parasites of the common carp from Tahtalı Dam Lake. METHODS The fish were transported live to the laboratory. They were investigated for ectoparasites and endoparasites. The parasite specimens were fixed and identified. RESULTS During the study, 47 common carp were caught monthly and 3 species of metazoan parasites were found: Dactyl...

The relationship between biological network architectures and evolution is unclear. Within the phylum nematoda olfaction represents a critical survival tool. For nematodes, olfaction contributes to multiple processes including the finding of food, hosts, and reproductive partners, making developmental decisions, and evading predators. Here we examine a dynamic nematode odor genetic network to i...

We analysed the helminth fauna associated with the lizard Mabuya dorsivittata (Scincidae) from a high-altitude area in Itatiaia National Park, Rio de Janeiro State, Brazil. Of the 16 lizards examined, 12 (75%) were infected by at least one helminth. Only two helminth species were found: Physaloptera retusa and Skrjabinodon spinosulus (Nematoda), the former with a prevalence of 68.8% and a mean ...

Abstract The variability of the organisms living in a given area constitute what is referred to as biodiversity, one nature’s fundamental properties, responsible for balance and stability ecosystems. loss biodiversity has been great concern scientists, especially because role played by human activities this regard, able lead irreversible circumstances.

In this study, nematodes were first reported in the amphipods, Ischyrocerus commensalis, collected from introduced and commercially important red king crabs, Paralithodes camtschaticus, coastal Barents Sea July 2022. Commensal amphipods registered on all crabs captured (n = 70, prevalence 100%). Further laboratory analysis revealed that 11 out of 467 amphipod individuals (prevalence 2.4%) harbo...
