“…Trochammina squamata is a euryhaline species (Gu et al, 2017) that has been recorded in coastal areas under the influence of several rivers (Li et al, 2014) and also in abyssal environments with an epifaunal and shallow-infaunal microhabitats (Enge et al, 2012). In the study area, this species was found living in the inner to mid shelf, on the gravely deposits, which would indicate a certain tolerance to relatively high hydrodynamic conditions.…”

This work is based on a compilation of benthic foraminiferal data collected in the Aveiro Lagoon and in the adjacent continental shelf and upper slope (center of Portugal). It intends to provide an overall analysis from transitional to the outer continental shelf of the occurrence and distribution of species in living and to present updated taxonomic data and illustrations of most of the species found in the in the Aveiro Lagoon and in the adjacent continental shelf including in total assemblages. Cluster analysis (CA) and Principal Components Analysis (PCA) interpreted as depth functions allow us to identify the main species in different ecoenvironments and sectors of the study area. The most unusual living assemblage was documented in the lagoon inlet under very strong tidal currents activity, composed mostly by the following species (both in living and total assemblages): Rotaliammina concava, Lepidodeuterammina ochracea, Quinqueloculina seminula, Gavelinopsis praegeri, Paratrochammina haynesi, Remaneica helgolandica and Remaneicella gonzalezi. The distribution patterns of some Trochamminidae and Remaneicidae species whose ecology and distribution pattern are poorly known, have proved to be a marker of more or less hydrodynamic and stable/unstable environments in coastal and transitional marine environments. OCORRÊNCIA DE FORAMINÍFEROS E DISTRIBUIÇÃO DAS PRINCIPAIS ESPÉCIES NA LAGOA DE AVEIRO E NA PLATAFORMA CONTINENTAL ADJACENTE (PORTUGAL)ResumoEste trabalho baseia-se numa compilação de dados foraminíferos bentónicos recolhidos na Laguna de Aveiro e na plataforma continental adjacente (centro de Portugal). Pretende efetuar uma análise geral da distribuição de espécies nas associações vivas e totais (vivas e mortas) na área de estudo, em função da profundidade. Pretende ainda apresentar dados taxonómicos e ilustrações da maioria das espécies encontradas na Laguna de Aveiro e na plataforma continental adjacente. A análise de agrupamento (CA) e a análise de componentes principais (PCA), em função da profundidade, permitem identificar as principais espécies em diferentes ecossistemas e setores da área de estudo. A associação viva mais invulgar foi encontrada na embocadura da Laguna de Aveiro, um ambiente sujeito a forte corrente de maré. Essa associação era composta principalmente pelas seguintes espécies (na associação viva e total): Rotaliammina concava, Lepidodeuterammina ochracea, Quinqueloculina seminula, Gavelinopsis praegeri, Paratrochammina haynesi, Remaneica helgolandica and Remaneicella gonzalezi. Os padrões de distribuição de algumas espécies de Trochamminidae e Remaneicidae, cuja ecologia e padrão de distribuição são pouco conhecidos, mostraram ser um marcador de ambientes mais ou menos hidrodinâmicos e de estabilidade/instabilidade do substrato em ambientes marinhos costeiros e de transição.

“…5), which was the first report of enriched intracellular nitrate (232 ± 26 pmol ind −1 ). P. tuberculatum , a typical cold‐water species, is widely reported to occur in the Yellow Sea in a narrow temperature range (7–13°C) and at water depth range of approximately 40–70 m; P. tuberculatum is significantly dominant in the YSCWM, which provides a relatively stable and comfortable environment (Li et al 2014; Dong et al 2019). The calcareous species H. nipponica produced the maximum average living depth in this study and stored the most intracellular nitrate (296 ± 49 pmol ind −1 ) (Fig.…”

Sedimentary denitrification accounts for more than half of the global marine fixed nitrogen loss, but this removal is often restricted by nitrate diffusive supply in sediments. The results of this study showed that foraminiferal nitrate transport may supply nitrate below the nitrate penetration depth and promote nitrogen removal in sediments in contact with oxic overlying water. Six dominant foraminiferal species in the Yellow Sea sediments accumulated high concentrations of intracellular nitrate (25–68 mM), which is 1000 times higher than the maximum pore water nitrate concentration. Notably, this is the first time that Protelphidium tuberculatum, the most dominant species at almost all stations, is reported to have elevated intracellular nitrate. P. tuberculatum contributes 45% to 92% of the foraminiferal intracellular nitrate pools and plays an important role in foraminiferal nitrate transport. The potential foraminiferal denitrification rates below the nitrate penetration depth induced by foraminiferal nitrate transport ranged from 4 to 117 μmol N m−2 d−1 and contributed 3% to 81% of sedimentary denitrification. The intensity of foraminiferal nitrate transport showed a negative correlation with the nitrate penetration depth and positively correlated with the chlorophyll a (Chl a) and chloroplastic pigment equivalent concentrations, which indicate that shallower redox depth (nitrate penetration depth) and increased food supply (Chl a, chloroplastic pigment equivalent) may promote foraminiferal nitrate transport. The trophic oxygen model was modified by adding the pore water nitrate to explain foraminiferal nitrate transport in various marine environments, and this modified trophic oxygen model predicts the observed high foraminiferal nitrate transport intensity.

“…One of the first comprehensive delineation of benthic and planktonic foraminiferal assemblages from a large area off the coast of China was provided by Zheng (1990). Recent studies have delved into the environmental significance of morphological variations in specific taxa (Lei et al, 2017a) while other research aimed to understand the environmental implications of foraminifera and their application in paleoenvironment reconstruction (Li et al, 2014;Lei et al, 2017b). Some researchers have tried to use benthic foraminifera as bio-monitors for trace metal pollution in marginal marine environments by investigating their relationships with heavy metals (Li et al, 2015) or evaluated their responses to an oil spill through specific indexes (Lei et al, 2015).…”
