  Meiofauna and nematode baseline study in the NORI-D license area of the Clarion Clipperton Fracture Zone, Pacific ? assessing biodiversity, heterogeneity, and rarity, Descrição: The abyssal seafloor in the Clarion Clipperton Fracture Zone, equatorial Pacific Ocean, is an area of increasing commercial and environmental interest owing to the abundant presence of high grade polymetallic nodules and the potential impacts from their targeted collection. Despite years of research, comprehensive baseline information on biodiversity, spatial and temporal patterns,and the ecology of benthic communities is incomplete, especially for microscopic fauna. An adequate environmental baseline study, including on metazoan meiofauna communities, is a requisite for exploration license holders to progress and deliver a comprehensive environmental assessment. In support of making such much-needed information available, we report on a deep community analysis of metazoan meiofauna and nematodes, based on over 900 samples from 86 stations in the NORI-D area (totaling ~150,000 counts and identifications), collected during two research campaigns (Oct-Nov 2020; May 2021). We investigated 1) the meiofauna higher taxa and nematode communities, 2) the environmental drivers of these communities, 3) the relationshipbetween habitat heterogeneity, sediment types, different areas of interest and the meiofauna communities, and 4) their use as indicators of the benthic environment. In assessing what these results mean, we focused on taxonomic and functional biodiversity, and patterns of heterogeneity and rarity in the analyzed communities.. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Aisha Ribeiro Mendes de Oliveira - Coordenador / Giovanni Amadeu Paiva dos Santos - Integrante / Jeroen Ingels - Integrante / Giovanna Lins Pessoa - Integrante / Nathan Lorenzo de Senna Gotti - Integrante / Yanka Vitória de Santana Lira - Integrante / Thalita Maria Santos Barbosa - Integrante / Renan Belém da Silva - Integrante / Débora Alissandra de Araújo França - Integrante / Flávia Juliana Lobato de França - Integrante / Letícia Pereira Pontes - Integrante / Vitória Vanessa Oliveira de Mendonça - Integrante / Raianne Amorim Cavalcante - Integrante / Lucas Melquíades de Omena - Integrante / Natally Souza da Silva Costa - Integrante / Emanuele Rodrigues Firmino - Integrante.
