Unlocking the genome of perch – From genes to ecology and back again

open access: yesEcology of Freshwater Fish, Volume 32, Issue 4, Page 677-702, October 2023., 2023
Abstract Eurasian perch Perca fluviatilis has been a popular model species for decades in the fields of aquatic ecology, community dynamics, behaviour, physiology and ecotoxicology. Yet, despite extensive research, the progress of integrating genomic perspective into existing ecological knowledge in perch has been relatively modest.

A global review of problematic and pathogenic parasites of farmed tilapia

open access: yesReviews in Aquaculture, Volume 15, Issue S1, Page 92-153, February 2023., 2023
Abstract Over the past 80 years, tilapia have been translocated globally for aquaculture; active production is recorded in >124 countries. Of 7 million tonnes of tilapia produced in aquaculture, 79% is from 79 countries outside the natural range of tilapia.

Population‐level variation in parasite resistance due to differences in immune initiation and rate of response

open access: yesEvolution Letters, Volume 6, Issue 2, Page 162-177, April 2022., 2022
Abstract Closely related populations often differ in resistance to a given parasite, as measured by infection success or failure. Yet, the immunological mechanisms of these evolved differences are rarely specified. Does resistance evolve via changes to the host's ability to recognize that an infection exists, actuate an effective immune response, or ...

Sensitization with Eustrongylides sp. (Nematoda: Dioctophymatidae) antigens induce production of specific IgG and IgE in murine model

open access: yesRevista Brasileira de Parasitologia Veterinária, 2021
Fish consumption plays an important role in human diet. Hoplias malabaricus, commonly known as traíra, is a freshwater fish widely appreciated in several Brazilian states and frequently infected by Eustrongylides sp. fourth-instar larvae (L4). The aim of

Molecular characterisation and histopathological study of Eustrongylides excisus nematode in the northern pike (Esox lucius).

open access: yesBulgarian Journal of Veterinary Medicine, 2023
Eustrongylides excisus is a parasitic nematode species whose life cycle requires two intermediate hosts, an aquatic oligochaete and a benthophagous fish.

ALTERED PREDATION SUSCEPTIBILITY OF MOSQUITOFISH INFECTED WITH EUSTRONGYLIDES IGNOTUS [PDF]

open access: yesJournal of Wildlife Diseases, 2001
Eustrongylides ignotus is a parasitic nematode whose definitive hosts are often piscivorous wading birds (Ciconiiformes). Several species of small fishes are intermediate hosts, while larger predatory fish may be paratenic (transport) hosts. We examined predation susceptibility of infected mosquitofish (Gambusia holbrooki) to three species of predatory

Nematodes in Hoplerytrinus unitaeniatus, Hoplias malabaricus and Pygocentrus nattereri (pisces characiformes) in Marajó Island, Brazil Nematóides em Hoplerytrinus unitaeniatus, Hoplias malabaricus e Pygocentrus nattereri (pisces characiformes) na Ilha de Marajó, Brasil

open access: yesRevista Brasileira de Parasitologia Veterinária, 2012
The aim of this study was to evaluate the tegument, musculature and mesentery of 102 specimens of Hoplerytrinus unitaeniatus, 104 of Hoplias malabaricus and 101 of Pygocentrus nattereri, from Arari Lake, Marajó Island, State of Pará, Brazil.

Scale‐dependent effects of host patch traits on species composition in a stickleback parasite metacommunity

open access: yesEcology, Volume 101, Issue 12, December 2020., 2020
Abstract A core goal of ecology is to understand the abiotic and biotic variables that regulate species distributions and community composition. A major obstacle is that the rules governing species distributions can change with spatial scale. Here, we illustrate this point using data from a spatially nested metacommunity of parasites infecting a ...

Competition from sea to mountain: Interactions and aggregation in low‐diversity monogenean and endohelminth communities in twospot livebearer Pseudoxiphophorus bimaculatus (Teleostei: Poeciliidae) populations in a neotropical river

open access: yesEcology and Evolution, Volume 10, Issue 17, Page 9115-9131, September 2020., 2020
The results of this work suggest that interspecific competition can occur in species‐poor, nonsaturated communities among specialist dominant species. Our analyses suggest also that aggregation is an important factor to determine local richness of parasites in fish populations and that intraspecific aggregation allows the coexistence of species in the ...
