Infection of Oxydoras kneri Bleecker, 1862 (Pisces, Doradidae) by the acanthocephalan Paracavisoma impudica (Diesing, 1851) Kritcher, 1957

open access: yesMemorias do Instituto Oswaldo Cruz, 1995
Infection of Oxydoras kneri by the acanthocephalan Paracavisoma impudica is described. The parasites do not penetrate deeply into the host gut wall and do not reach the muscularis layers.

CONDITION FACTOR AND ECOLOGY OF ENDOHELMINTHS IN Metynnis lippincottianus FROM THE CURIAÚ RIVER, IN EASTERN AMAZON (BRAZIL)

open access: yesBoletim do Instituto de Pesca, 2020
Fish are among the vertebrate groups most susceptible to parasitic infections due to environmental characteristics that can favor the development of parasites; also, position of the host in food web has been associated with the parasitism.

Marine Parasite Biogeography Mirrors Host Patterns Across Latitude, Area, and Diversity

open access: yesNew Zealand Journal of Zoology, Volume 53, Issue 2, June 2026.
Parasites are integral components of biodiversity, yet they remain poorly represented in large‐scale biogeographic theory. In this study, we test whether marine parasites follow three macroecological patterns established for free‐living taxa, namely that parasite species richness: (1) scales positively with area (both host body size and geographic area)

Native and Non‐Native Populations Respond Unevenly to River Barrier Removals

open access: yesGlobal Change Biology, Volume 32, Issue 6, June 2026.
While barrier removals restore river connectivity and promote recovery of native populations, they may also facilitate non‐native species, creating a ‘connectivity conundrum’. Using a systematic review and meta‐analysis, we show that both native and non‐native populations can benefit from barrier removal, with outcomes being context‐dependent ...

DNA Metabarcoding Reveals Unexpected Predator–Prey–Microbial Dynamics in the Southern Right Whale (Eubalaena australis)

open access: yesMolecular Ecology, Volume 35, Issue 12, June 2026.
ABSTRACT Southern right whale (Eubalaena australis; SRW) populations are recovering from the impacts of commercial whaling, however, recovery has been spatially variable, with strong associations between reproduction and prey availability. The diet of SRWs has not been widely examined, and with SRW foraging shifting away from high‐latitude foraging ...

Intestinal Parasite Community Dynamics in the Critically Endangered Chinese Alligator (Alligator sinensis): Multifactorial Insights From 18S rRNA Amplicon Sequencing

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Our results firstly demonstrate the structure of parasite communities in A. sinensis and clarify how they are shaped by interacting ecological and management factors, providing critical baseline data for future research. ABSTRACT The intestinal parasite communities of vertebrates are shaped by complex interactions among biological, environmental, and ...

Algunos helmintos parásitos de la gaviota peruana (Larus belcheri)

open access: yesRevista Peruana de Biología, 2019
La información sobre helmintos parásitos de aves marinas es muy limitada en el Perú. En el presente trabajo, se identificaron helmintos colectados de la gaviota peruana (Larus belcheri) provenientes de algunas playas de Lima (Pucusana, Chorrillos ...

Marine Fish Parasites: A Bibliometric Review

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
This bibliometric study analyzes 11,368 publications on marine fish parasites from Web of Science and Scopus. The results reveal leading countries, institutions, and journals, and identify three main research clusters: parasitology, genetics, and marine ecology. Recent thematic evolution highlights a growing focus on aquaculture applications, including
