Freshwater trematodes differ from marine trematodes in patterns connected with division of labor [PDF]

open access: yes
Background Prior research suggests that trematode rediae, a developmental stage of trematode parasites that reproduce clonally within a snail host, show evidence of division of labor (DOL).

Does bigger mean sicker? A systematic review and meta‐analysis of the intraspecific relationship between host body size and parasite infection across vertebrate taxa

open access: yesOikos, EarlyView.
Elucidating the determinants of parasite infection levels of individuals within a population is a basic but important step for understanding the roles of parasites in natural systems. Among intraspecific studies on vertebrate hosts and metazoan parasites, host body size (length/mass) is probably the most frequently reported factor determining parasite ...

Variety dixenic life cycles of trematode from Вithyniidae snails (Mollusca: Gastropoda: Prosobranchia) Palaearctic

open access: yesРоссийский паразитологический журнал, 2016
Trematodes from 11 families have dixenic life cycles. Primary dixenic life cycles are typical for trematodes families Notocotylidae and Psilostomidae. Secondary dixenic life cycles have 3 versions.

Digenean trematodes (Trematoda: Digenea) parasitizing the digestive system of the great cormorant (Phalacrocorax carbo) in Hungary

open access: yesHelminthologia
Great cormorants (Phalacrocorax carbo) are widespread piscivorous birds, which cause huge economic losses in the fish fauna worldwide. As a consequence of their predatory behaviour, they serve as definitive hosts for many digenean trematodes, and their ...

Recent Advances and Potential Future Applications of MALDI-TOF Mass Spectrometry for Identification of Helminths

open access: yesDiagnostics, 2022
Helminth infections caused by nematodes, trematodes, and cestodes are major neglected tropical diseases and of great medical and veterinary relevance. At present, diagnosis of helminthic diseases is mainly based on microscopic observation of different ...

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Social Recognition in Ants and Trematodes [PDF]

open access: yes, 2022
Life can be hierarchically organized into units of reproduction that function as “individuals”. In evolutionary theory, individuals are typically cells or multicellular bodies, but the boundaries or definitions of individuals are ambiguous.

Black Carp Mylopharyngodon piceus reproductive development and maturation in the Mississippi River basin

open access: yesJournal of Fish Biology, EarlyView.
Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...

The effects of playbacks of anthropogenic noise on the anti‐predator behaviour of Pacific sand lance, Ammodytes personatus

open access: yesJournal of Fish Biology, EarlyView.
Abstract Noise from human activities has increased and been shown to negatively impact marine animals. Marine mammals and fish are vulnerable to anthropogenic noise because they rely on sound to communicate, find food, avoid predators and sense their environment. Forage fish are small schooling pelagic fish, important to many predators and instrumental
