“…Electron microscopy was used for the identification of some species, e.g., Skeletonema (Bergesch et al, 2009) and Pseudonitzschia (Hagström et al, 2011). Thalassiosira, however, was identified and counted at the genus level due to identification difficulties using the optical microscope (Garcia and Odebrecht, 2009). Other difficulties identifying species were grouped at higher taxonomic levels (i.e., centric and pennate diatoms, armored or unarmored gymnodinioid dinoflagellates).…”

Abstract. Estuaries are among the most productive aquatic ecosystems and provide important ecological and economic services in coastal areas. However, estuarine systems have been threatened worldwide by natural and anthropogenic impacts acting on local, regional, and global scales. Long-term ecological studies contribute to the understanding and management of estuarine functioning and provide the baseline information for detection changes and modeling of predictive scenarios. Here, we describe long-term data on the biodiversity and physico-chemical parameters obtained from 1993 to 2016 for the Patos Lagoon estuary and adjacent marine coast (PLEA), in southern Brazil. We report 8 datasets containing 6972 sampling events with the occurrence and abundance records of 275 species (kingdoms: Bacteria, Protozoa, Chromista, Plantae, and Animalia) of functional groups plankton, benthos, and nekton. Datasets also include 22 190 abiotic records. The database is published in the Global Biodiversity Information Facility (GBIF) repository (see Sect. 3 “Data availability” and Table 3). The present compendium represents one of the most comprehensive and longest datasets from primary producers to top predators in an estuarine coastal system in South America, and their availability will be an important contribution to the understanding and predictability of estuarine dynamics around the world.

“…Novo registro para o Nordeste do Brasil. Espécie raramente encontrada no Sul do Brasil (Garcia & Odebrecht, 2009) e Argentina Sunesen & Lavigne, 2002), mas abundante e frequente nas amostras do presente estudo. Características e dimensões de acordo com o protólogo (Fryxell & Hasle, 1977) e com outros trabalhos para o Oceano Atlântico Sul Sunesen & Lavigne, 2002;Garcia & Odebrecht, 2009).…”

Os estuários são ecossistemas altamente produtivos e dinâmicos, sendo o fitoplâncton o principal produtor primário, e as diatomáceas cêntricas são o grupo mais abundante observado no fitoplâncton marinho e estuarino. Nesse contexto, o objetivo deste estudo foi realizar o levantamento taxonômico das diatomáceas cêntricas planctônicas(Coscinodiscophyceae e Mediophyceae) de dois estuários tropicais localizados no Nordeste do Brasil. O estudo foi realizado antes do maior impacto de derramamento de óleo ocorrido no Brasil em 2019. Trinta e seis táxons foram identificados. Mediophyceae foi a classe mais representativa, com 24 espécies. Coscinodiscus foi o gênero com maior número de espécies identificadas, seguido de Chaetoceros e Thalassiosira. A espécie Chaetoceros filiferus Karsten foi reportada pela primeira vez para o Brasil, enquanto Paralia fenestrata (Sawai & Nagumo) e Shionodiscus endoseriatus (Hasle & Fryxell) Alverson consistem em novos registros para o Nordeste do Brasil e Thalassiosira lineata Jousé para o estado de Pernambuco. Descrições, ilustrações e comentários sobre as variações morfológicas e métricas dos táxons foram apresentados. Os resultados evidenciam a importância de estudos florísticos para oconhecimento da flora de diatomáceas de ambientes marinhos tropicais, além de servir como um estudo de base para trabalhos futuros nos estuários estudados.
