Lost and Found: Piwi and Argonaute Pathways in Flatworms

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Platyhelminthes comprise one of the major phyla of invertebrate animals, inhabiting a wide range of ecosystems, and one of the most successful in adapting to parasitic life.

Platyhelminths as paleogeographical indicators [PDF]

open access: yesHydrobiologia, 1995
Turbellarians do not feature as examples in the present discussions on the theory and method of analytical biogeography. It is argued, however, that turbellarian distributional records form good examples of large-scale biogeographic patterns resulting from continental breakup.

A global assessment of abyssal–hadal vermiform lebensspuren: Functional consistency with depth

open access: yesLimnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Lebensspuren—sedimentary traces produced by benthic organisms—are widespread on deep‐sea floors but remain infrequently reported from abyssal (~ 3000–6000) and hadal (> 6000 m) environments. Here, we present the most comprehensive assessment of abyssal–hadal vermiform lebensspuren to date, spanning multiple ocean basins and reaching full‐ocean

Platyhelminthes ou apenas semelhantes a Platyhelminthes? Relações filogenéticas dos principais grupos de turbelários

open access: yes, 2013
The phylum Platyhelminthes has been traditionally subdivided into four classes, viz. Turbellaria, Trematoda, Monogenea e Cestoda. However, phylogenetic analyses indicated that the class Turbellaria was not well defined due to the lack of clear ...

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats

open access: yesLimnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

Two new families (Acari: Alicorhagiidae and Platyhelminthes: Prorhynchidae) reported for the Hungarian fauna From leaf litter in the Bükk Mountains [PDF]

open access: yesOpuscula Zoologica Instituti Zoosystematici et Oecologici Universitatis Budapestinensis, 2016
Two new members of the Hungarian fauna are reported, both of them were collected in beech forest leaf litter in the Bükk Mountains, North-East Hungary: Alicorhagia fragilis Berlese, 1910 (Arthropoda: Arachnida: Acari: Sarcoptiformes: Endeostigmata ...

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)

Novas ocorrências de metacercária de Austrodiplostomum compactum (Lutz, 1928) (Platyhelminthes: Digenea) parasito de olhos de peixes da Bacia do Rio Paraná New occurrences of metacercariae of Austrodiplostomum compactum (Lutz, 1928) (Platyhelminthes: Digenea) eye flukes of fish from the Paraná Basin

open access: yesRevista Brasileira de Parasitologia Veterinária, 2008
Austrodiplostomum compactum (Platyhelminthes: Digenea) parasita os olhos de várias de espécies de peixes. A presença deste parasito, em casos extremos, pode causar exoftalmia, deslocamento da retina, opacidade do cristalino e cegueira ou até a morte.

Torrent frogs have fewer macroparasites but higher rates of chytrid infection in landscapes with smaller forest cover

open access: yesEcosphere, 2020
Deforestation can compromise ecological processes and biotic interactions, including the host–parasite relationship. While some parasites infect only one host, others require multiple hosts to complete their complex life cycles.

Staining of Platyhelminthes by herbal dyes: An eco-friendly technique for the taxonomist [PDF]

open access: yesVeterinary World, 2015
Aim: An environment compatible technique to stain Platyhelminthes, Fasciola gigantica, Gastrothylax crumenifer, Taenia solium, and Moniezia expansa using aqueous and alcoholic extract of sugar beet (Beta vulgaris), China rose (Hibiscus rosasinensis), and
