“…Garraffoni (2017) noted three major gaps in the current knowledge about Brazilian freshwater Gastrotricha: (a) most of the Brazilian inland waters had never been sampled before. Records, in fact, show a strong bias because most of the samplings were conducted in the State of São Paulo, and only a few in other states); (b) identification keys for a great number of genera do not exist and there is difficulty in obtaining classic and old literature from the end of the century XIX and early century XX; and (c) reference collections about the taxon in Brazilian Museums are absent (see Garraffoni et al, 2019b).…”

Information regarding the records of Brazilian marine gastrotrichs is presented. We systematized and organized the existing information associated with approximately 23 species (belonging to the genera Aspidiophorus, Chaetonotus, Crasiella, Dactylopodola, Dendrodasys, Draculiciteria, Halichaetonotus, Heteroxenotrichula, Kryptodasys, Macrodasys, Pseudostomella, Ptychostomella, Urodasys and Xenotrichula) from the Brazilian coast (eight endemic) and their 1,581 records from 36 marine ecoregions of the world. A link is provided to an on-line interactive map where all occurrences for each species are shown, accompanied by geographic coordinates, oceans, countries, cities, granulometric characteristics and ecoregions. Furthermore, a critical analysis of the geographical distribution of Brazilian marine gastrotrichs, an estimate of the number of undescribed species, a summary of the existence and status of taxonomical collections are also presented.

“…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. De acordo com Garraffoni e Araújo (2010), o número de espécies de Gastrotricha no Brasil encontra-se subestimado. A diversidade desse táxon foi objeto de investigação detalhada em alguns pontos do território brasileiro, destacando-se os trabalhos de Kisielewski (1991), Todaro e Rocha (2004, Garraffoni e Araújo, (2010), Garraffoni e Melchior (2015), Garraffoni (2017), Garraffoni, Di Domenico e Hochberg (2017), Campos e Garraffoni (2019) e Garraffoni et al (2020). Garraffoni e Araújo (2010) apresentam uma chave para os Gastrotricha de águas marinhas e continentais no Brasil, além de descrever metodologias de coleta e preservação de espécimes de gastrótricos e padronizar a terminologia técnica utilizada em língua portuguesa para descrever esse táxon.…”

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.

“…Due to the meiofaunal body size and challenging identification process, the knowledge about gastrotrichs and tardigrades' diversity in the world is underestimated (Vicente 2010, Appeltans et al 2012Balsamo et al 2014, 2020, Fonseca et al 2018, Garraffoni et al 2019b). Notwithstanding, a few studies have aimed to reveal the richness and distributional patterns of these two freshwater and limnoterrestrial meiofauna taxa in Brazil (de Barros R 1939a, b, 1942a, b, 1943, Kisielewski 1991, Assunção 1999, Pilato et al 2002b, Garraffoni et al 2010, 2017a, b, 2019a, Garraffoni & Melchior 2015, Araújo et al 2013, Rocha et al 2016, Garraffoni 2017, de Barros RC 2020. This study aims to contribute to this knowledge by presenting the first records of gastrotrichs and tardigrades at the Biological Reserve of Fundação Serra do Japi, an extensive area of Atlantic Forest located in São Paulo State.…”

Serra do Japi, located in the southeast of São Paulo State, is considered a priority area for conservation, as it houses original Atlantic Forest cover remains. Despite the significant number of studies about vertebrates and invertebrates that were carried out in this region, the meiofauna biodiversity is completely unknown. Thus, the present study aimed to investigate for the first time freshwater Gastrotricha and limnoterrestrial Tardigrada in Serra do Japi Biological Reserve. Samples of sediments, periphyton and floating vegetation in reservoirs and natural lagoons, and mosses growing on native and non-native tree trunks were collected in May 2019. At least five gastrotrichs morphotypes were identified and three of them were formally described: Chaetonotus acanthocephalus, C. dadayi (first record in Brazil), and Heterolepidoderma mariae (first record outside the type locality). In regards to tardigrades, twelve morphotypes were identified and four of them were formally described: Pseudechiniscus juanitae, Minibiotus cf. acontistus, Echiniscus dreyfusi and Itaquascon umbellinae (last two species reported for the first time outside the type locality). This study reinforces that meiofaunal diversity and distribution have been underestimated, even in one of the five largest hotspots in the world.
