Neohexostoma gymnosardae n. sp. (Monogenea, Hexostomatidae), a gill parasite of Gymnosarda unicolor (Valenciennes) (Teleostei, Scombridae) in the South China Sea

open access: yesParasite, 2020
Parasite biodiversity of fish in coral reefs of the South China Sea is still incompletely explored. We describe here a new species of Neohexostoma (Monogenea: Hexostomatidae) from the gill filaments of the dogtooth tuna Gymnosarda unicolor (Scombridae ...

Fish morphological and parasitological traits as ecological indicators of habitat quality in a Mediterranean coastal lagoon

open access: yesAquatic Conservation: Marine and Freshwater Ecosystems, Volume 33, Issue 11, Page 1229-1244, November 2023., 2023
Abstract Coastal lagoons are key ‘transitional’ aquatic environments for biodiversity conservation. Ecological indicators are useful tools for the management of water resources in the European Union. Among different biological communities, fish are a very sensitive tool to assess environmental integrity.

Hatching Strategies in Monogenean (Platyhelminth) Parasites that Facilitate Host Infection [PDF]

open access: yes, 2011
In parasites, environmental cues may influence hatching of eggs and enhance the success of infections. The two major endoparasitic groups of parasitic platyhelminths, cestodes (tapeworms) and digeneans (flukes), typically have high fecundity, infect more

Parasites and Pollutants: Effects of Multiple Stressors on Aquatic Organisms

open access: yesEnvironmental Toxicology and Chemistry, Volume 42, Issue 9, Page 1946-1959, September 2023., 2023
Abstract Parasites can affect their hosts in various ways, and this implies that parasites may act as additional biotic stressors in a multiple‐stressor scenario, resembling conditions often found in the field if, for example, pollutants and parasites occur simultaneously.

A new species of Dermopristis Kearn, Whittington & Evans-Gowing, 2010 (Monogenea: Microbothriidae), with observations on associations between the gut diverticula and reproductive system and on the presence of denticles in the nasal fossae of the host Glaucostegus typus (Bennett) (Elasmobranchii: Rhinobatidae) [PDF]

open access: yes, 2011
Dermopristis cairae n. sp. (Microbothriidae) is described from the skin and possibly from the nasal fossae of the giant shovelnosed ray Glaucostegus typus (Bennett). The new species is distinguished from D.

Variation in the parasite communities of three co‐occurring herbivorous coral reef fishes

open access: yesJournal of Fish Biology, Volume 102, Issue 4, Page 757-772, April 2023., 2023
Abstract Parasites are important, diverse, and abundant components of natural ecosystems and can influence the behaviour and health of their hosts, inter‐ and intraspecific interactions, and ultimately community structure. Coral reefs are one of the world's most biodiverse ecosystems, yet our understanding of the abundance, diversity, and composition ...
