Neogosseidae (Gastrotricha, Chaetonotida) from the iSimangaliso Wetland Park, KwaZulu-Natal, South Africa [PDF]

ZooKeys, 2013
Among the mostly benthic gastrotrichs, the Neogosseidae (Gastrotricha, Chaetonotida) are particularly interesting from an evolutionary point of view in virtue of their planktonic lifestyle; yet, they are poorly known and uncertainties concerning ...

Long distance dispersal and pseudo-cryptic species in Gastrotricha: first description of a new species (Chaetonotida, Chaetonotidae, Polymerurus) from an oceanic island with volcanic rocks

European Journal of Taxonomy, 2021
The majority of meiofaunal organisms have limited abilities to disperse over long distances, yet they may still have disjointed distributions. Many studies have found evidence of long distance meiofauna dispersal due to passive transport by wind and/or ...

A new species of freshwater Chaetonotidae (Gastrotricha, Chaetonotida) from Obodska Cave (Montenegro) based on morphological and molecular characters

European Journal of Taxonomy, 2017
Gastrotricha is a cosmopolitan phylum of aquatic and semi-aquatic invertebrates that comprises about 820 described species. Current knowledge regarding freshwater gastrotrichs inhabiting caves is extremely poor and there are no extant data regarding ...

First Investigation of the Marine Gastrotrich Fauna from the Waters of North Tunisia, with the Description of a New Species of Halichaetonotus (Gastrotricha, Chaetonotida) [PDF]

Diversity
Gastrotrichs (hairy bellies) are microscopic, acoelomate worms that live in freshwater and marine environments and represent one of the significant components of the meiobenthic communities. There are over 520 marine species, and several of them are also

Gastrotricha – not only in sediments: new epiphytic species of Chaetonotida from the Jubilee Greenhouse of the Botanical Garden in Kraków

European Journal of Taxonomy, 2019
Although Gastrotricha have previously been recorded in bottom sediments of greenhouses as well as in micro-reservoirs of Bromeliaceae, palm houses provide a more specific microhabitat for these animals that often originate from different regions of the ...

Applicability of environmental DNA metabarcoding for the hyporheic zone of a stream bed

Environmental DNA, Volume 5, Issue 6, Page 1667-1678, November 2023., 2023
To understand whole riverine biodiversity, including hyporheric zones, it is necessary to develop a method to easily and accurately detect hyporheos communities in hyporheic zones, which currently remains poorly understood. Using eDNA metabarcoding for cytochrome‐c oxidase subunit I (COI) regions, we successfully detected various hyporheos and benthos ...
