“…The majority of marine gastrotrich sampling sites are in the Northern Hemisphere [51], while in tropical countries the investigated areas are very scattered [14,16,17,30,52]. The Brazilian coast is poorly sampled, although it shows a high diversity of marine gastrotrichs, according to current literature [5,51]. In terms of knowledge of Turbanellidae diversity from Brazil, there are at least four candidate species to be formally described (one Turbanella species and three Paraturbanella species) from the north coast of São Paulo State [34,35].…”

“…The latter group is composed in its majority of hermaphroditic and marine species, which live interstitially in sandy bottoms [2,4]. The order Macrodasyida includes 10 families, 36 genera and approximately 380 described species [2,5,6]. They have a strap-shaped body, a pharynx with pharyngeal pores, and, usually, numerous adhesive tubes in the anterior, lateral and posterior regions.…”

The family Turbanellidae includes Paraturbanella and five other genera. Despite the fact that the monophyly of these genera were not satisfactorily tested, species belonging to the genus Paraturbanella are distinguished from turbanellids by sharing a peculiar group of tubes on the ventrolateral side of the anterior pharyngeal region known as “dohrni” tubes. In this study, Paraturbanella tricaudata species nova (sp. nov.) from the intertidal zone of a sandy beach in Trindade (Rio de Janeiro State) and the sublittoral sand of Prumirim Island (São Paulo State), Brazil, is described. The new species can be distinguished from all other Paraturbanella species by the presence of three caudal cones (one medial and two laterals to it) and peculiar arrangement of the male system. This is the first description of a Paraturbanella species from Brazil and the third registered from the Southern Hemisphere (as opposed to 19 species in the Northern Hemisphere); thus, knowledge of marine gastrotrichs biodiversity in this region is far from satisfactory.

“…A ordem Chaetonotida (ou Chaetonotoidea) compreende a maioria das espécies de Gastrotricha (HUMMON, 1982;GIERE, 2009;CAMPOS;GARRAFFONI, 2019;GRILLI, 2022). Ela se diferencia pela ausência de poros faríngeos e presença de lúmen da faringe em formato de "Y", um ou mais pares de protonefrídios e Brazilian Journal of Development, Curitiba, v.9, n.

O avanço das técnicas de microscopia, bioimagem, análise molecular e bioinformática possibilitou a investigação detalhada de organismos invisíveis a olho nu, o que resultou na descoberta de diversos táxons previamente desconhecidos. Com base nessas descobertas, hipóteses filogenéticas foram atualizadas e novos conceitos foram incorporados ao conhecimento sobre a diversidade da vida na Terra. A utilização de mapas conceituais como organizadores gráficos auxilia no entendimento das complexidades inerentes à descrição dos caracteres biológicos. Nesse sentido, o objetivo do presente estudo foi elaborar um mapa conceitual para sistematizar, de forma diagramática, caracteres gerais e específicos sobre o táxon Chaetonotida, pertencente ao filo Gastrotricha. Por meio da análise de publicações especializadas, foram identificados diversos termos relacionados a essa linhagem evolutiva, os quais foram conectados em proposições lógicas usando o software CmapTools. O mapa conceitual resultante serve como um panorama informativo, permitindo um acesso mais dinâmico à caracterização desses animais enigmáticos e proporcionando um subsídio para promover o conhecimento de forma mais visível. Desta forma, como elemento imagético para apresentar informações, o mapa conceitual pode representar um veículo eficaz de divulgação de conhecimento sobre a diversidade biológica.

“…This prodromal research on gastrotrichs primarily involves acquiring and georeferencing published information on freshwater taxa. Creating interactive maps will allow for an easy and modern worldwide sharing of information to benefit taxonomists, conservation biologists, policymakers, and the wider public [40].…”

Status of the Italian Freshwater Gastrotricha Biodiversity, with the Creation of an Interactive GIS-Based Web Map

Diversity

View full text Add to dashboard Cite

Gastrotricha are microscopic benthic animals found in almost all water bodies. To date, over 890 species distributed in 71 genera, 18 families, and two orders are known. There are 376 freshwater species, and several are also found in Italy; however, a compendium of the studies carried out so far, and a georeferenced distribution of the species, still need to be provided. This project summarizes information about the diversity and geographic distribution of Italian gastrotrichs. Diversity data, acquired over 239 years, were reviewed and corrected based on taxonomic and nomenclatural updates and, in addition to distribution information, were organized into a data matrix valuable for statistical analysis. The data were fed into geographic information system software to understand the overall figures more easily. The results indicated that Italy is one of the best-known countries regarding freshwater gastrotrichs. With 92 species in 17 genera and three families from 61 investigated localities, Italy counts 17 type localities and 19 endemic species. Despite this high biodiversity, many Italian regions still need to be investigated, and should, therefore, be the focus of future research. The implementation of a web-mapping plugin enabled the creation of interactive maps for an easy and modern method for sharing the work done, and the information acquired.
