“…Lazaro Laut; Iara Clemente; Maria Virginia Alves Martins; Fabrizio Frontalini; Débora Raposo; Pierre Belart; Renan Habib; Rafael Fortes & Maria Lucia Lorini are more stable than in meso-macrotidal and because of this, the number of foraminifera species can be more than forty (Laut et al, 2007).…”

“…On the contrary, the microtidal estuaries associated with mangroves in South America have a low number of species due to the rainfall intensity in the tropical and intertropical zone (Laut et al, 2007). Santa-Cruz & Dias-Brito (2006) identified 24 species in Bertioga Channels in São Paulo coast (23°58'S -46°17'W) and Laut et al (2007) identified 28 foraminiferal species in Itacorubi estuary (27º34'S -48º32"W), in Brazil.…”

“…Among the dominant species of foraminifera in the Godineau River Estuary, A. tepida is considered one of the most resistant ones to environmental stress (Boltovskoy, 1965) and pollutants (Laut et al, 2007). It frequently occurs in shallow water environments such as lagoons, deltas and estuaries (Coccioni, 2000).…”

“…Laut et al (2007) suggested that A. mexicana displays a symbiotic relationship with sulphate reducing bacteria in Itacorubí River Estuary, at south of Brazil. However, Laut et al (2016) observed that the abundance of this species declines with the increase of bacterial carbon and total organic matter content in other Brazilian estuaries.…”

At the mouth of Paraíba do Sul River estuary (21°28'S -41°02'W), in Rio de Janeiro State (southeast Brazil), a large hydrographic basin, Laut et al (2011a) found only 15 foraminiferal species.…”

In the Godineau River Estuary, located in Trinidad Island (off the northeast coast of Venezuela), were found 114 taxa of foraminifera and 17 of thecamoebians in the dead fauna. Most of the identified foraminiferal species were rare because they were transported from the Gulf of Paria to this estuary. The autochthonous foraminiferal assemblage was represented by several tropical estuarine species such as Ammonia tepida, Ammotium salsum, Arenoparrella mexicana, Cribroelphidium excavatum, Ammonia parkinsoniana, Haplophragmoides wilberti, Miliammina fusca and Ammotium cassis. The thecamoebians assemblages, found in the inner part of this estuary, were dominated by Cyclopyxis spp., Centropyxis spp., Difflugia corona and Difflugia urceolata. The relative abundance of the main species of foraminifera and thecamoebians were analyzed through Q-mode and R-mode cluster analyses. Statistical results revealed the presence of three different environments in the Godineau River Estuary related to different hydrodynamic conditions and more or less oceanic or fluvial influence. The first sector represents the most confined region of the estuary and was mainly composed by agglutinated foraminifera together with thecamoebians. The second sector was located in the middle part of the estuary and was associated with the presence of brackish waters. The third sector denotes the outermost part of the estuary characterized by the greatest hydrodynamic activity and highest oceanic influence within the estuary. This sector was marked by the occurrence of a large number typical-marine foraminifera species.

Muitas das espécies de foraminíferos identificadas são raras e pequenas indicando transporte do Golfo de Paria para dentro do estuário. Os foraminíferos autóctones foram representados por espécies típicas de estuários tropicais como Ammonia tepida, Ammotium salsum, Arenoparrella mexicana, Cribroelphidium excavatum, Ammonia parkinsoniana, Haplophragmoides wilberti, Miliammina fusca e Ammotium cassis. As tecamebas eram abundantes na região mais interna do estuário. As espécies dominantes foram Cyclopyxis spp., Centropyxis spp., Difflugia corona e Difflugia urceolata. A abundância relativa das principais espécies foi analisada através da análise de agrupamento em modo Q e R. As análises estatísticas revelaram a existência de três ambientes distintos no estuário que são relacionados a diferentes condições hidrodinâmicas de maior ou menor influência marinha ou fluvial. O primeiro setor representou a região mais confinada do estuário composta por foraminíferos aglutinantes junto com tecamebas O segundo setor foi localizado na região intermediária do estuário e era tipicamente um ambiente salobro (mixohalino). O terceiro sector, situado na parte mais e...
