Antagonistic Rewiring and Turnover Patterns in a Neotropical Fish–Parasite Metanetwork

Freshwater Biology, Volume 70, Issue 7, July 2025.
ABSTRACT Integrating beta‐diversity and network analyses is an emerging approach for understanding the spatial structure of species communities. For instance, although the presence of hosts affects parasite species distribution, environmental factors can either restrict or promote the occurrence of certain parasite species by changing the abundance of ...

Elevated fish growth yet postponed maturation during intense marine heatwaves

Ecological Applications, Volume 35, Issue 4, June 2025.
Abstract In the last decade, the northeast Pacific Ocean has experienced new climatic extremes with the occurrence of several marine heatwaves (MHWs), prolonged periods of warmer‐than‐normal ocean temperatures, likely as a result of anthropogenic climate change.

Syllogistic System for the Propagation of Parasites. The Case of Schistosomatidae (Trematoda: Digenea)

Studies in Logic, Grammar and Rhetoric, 2015
In the paper, a new syllogistic system is built up. This system simulates a massive-parallel behavior in the propagation of collectives of parasites.

Diversity of digeneans parasitizing Mullus barbatus and Mullus surmuletus (Teleostean, Mullidae) off the coast of Algerian

Helminthologia, 2023
Mullus barbatus and Mullus surmuletus (Perciformes, Mullidae) are a common marine teleost of great commercial importance in many coastal areas. We studied the communities of Digenea species in two congeneric Mullidae hosts collected on the Algerian coast

Metabarcoding Unveils the Diversity and Dynamics of In Situ Diet and Symbionts Associated With Copepods in Chinese Coastal Waters

Diversity and Distributions, Volume 31, Issue 6, June 2025.
ABSTRACT Aim Copepods are the key secondary producers in marine ecosystems, yet their in situ diet and symbionts remain underexplored due to technical challenges, limiting our understanding of their population dynamics and ecological functions. Using DNA metabarcoding, we jointly characterised the natural diet and symbionts of copepods across Chinese ...

A fine‐scale phylogenetic assessment of digenean trematodes in central Alberta reveals we have yet to uncover their total diversity

Ecology and Evolution, 2019
Despite over 100 years of digenean trematode parasite species descriptions, from a wide diversity of vertebrate and invertebrate host species, our ability to recognize the diversity of trematode species within a single lake remains an incredible ...

Slow Invaders Going Fast: New Data of Exotic Slugs (Gastropoda: Eupulmonata) From Spain

Ecology and Evolution, Volume 15, Issue 5, May 2025.
Morphological and genetical confirmation of the occurrence of two non‐native terrestrial slugs in the Iberian Peninsula (northern Spain): Ambigolimax parvipenis and Boettgerilla pallens. ABSTRACT Invasive species are a major concern in the current scenario of biodiversity loss. Most studies focus on vertebrates and insects, while other groups have been

Evaluating the In Vitro Anthelmintic Activity of Zinc Oxide Nanoparticles (ZnO‐NPs) Against the Adult Stages of Fasciola hepatica

Veterinary Medicine and Science, Volume 11, Issue 1, January 2025.
Resistance to currently deployed flukicide is a growing health problem. This study evaluated the in vitro anthelmintic activity of zinc oxide nanoparticles (ZnO‐NPs) at 0.05, 0.10 and 0.12 mg/mL against Fasciola hepatica. The fastest mortality and paralysis rates of flukes were obtained at 0.12 mg/mL of ZnO‐NPs. Furthermore, SEM results showed complete

Report ofNeospirorchis schistosomatoides Price 1934 (Digenea: Spirorchiidae) infecting a Green Turtle, Chelonia mydas Linnaeus, 1758 (Testudines, Cheloniidae), from Brazil

Helminthologia, 2016
We report the occurrence of Neospirorchis schistosomatoidesPrice 1934 in a juvenile green turtle (Chelonia mydas L.1758) from the Brazilian coast. This species has been reported only in green turtles from the USA, Bermuda and Australia.

Four Species of Digeneans (Trematoda, Opecoelidae) of the Gilthead Seabream Sparus aurata (Teleostei, Sparidae) off the Algerian Coast in the Mediterranean Sea

Zoodiversity
A study was conducted between May 2020 and April 2022, in an attempt to investigate the diversity of digeneans infecting the digestive tract of the gilthead sea bream Sparus aurata (Linnaeus, 1758) (Sparidae) off the Algerian coast.
