Environmental Compartments of Arade River Estuary, South of Portugal, Based on Distribution and Ecology of Foraminifera

Multiproxies (Benthic Foraminifera, Ostracods and Biopolymers) Approach Applied to Identify the Environmental Partitioning of the Guadiana River Estuary (Iberian Peninsula)

“…However, the specific richness was comparable to the values documented by Camacho et al (2014Camacho et al ( , 2015. This value is higher than that found in other estuaries of the south of Iberian Peninsula such as that of Arade River (Laut et al, 2014) and Tinto-Odiel system (Ruiz et al, 2005). In the Guadiana River estuary, mostly cosmopolitan and calcareous species (42 species) were found such as A. tepida, A.…”

“…The species A. mexicana, E. polystoma, E. macrescens, S. lobata and T. salsa should be also linked with this contribution (Souza et al, 2010). The great predominance of M. fusca species in this group is related to an increase of fluvial influence (Debenay et al, 2003;Camacho et al, 2014Camacho et al, , 2015Laut et al, 2014). The miliolids such as Q. seminula have been found in several transitional ecossystems associated with sandy sediment and basic to neutral pH (Eichler et al, 2003;Martins et al, 2013Martins et al, , 2014Laut et al, 2014).…”

“…They are cosmopolitan and occur in other Iberian Peninsula estuaries and lagoons, such as the Arade river (Laut et al, 2014) and Ria de Aveiro (Martins et al, 2010(Martins et al, , 2013(Martins et al, , 2014. These species have high tolerance to salinity variations and tend to live in brackish environments such as estuaries, mangroves and salt marshes (Souza et al, 2010).…”

“…However, the studies on ostracods fauna in coastal regions started only in 1960. According to Laut et al (2014), the current knowledge of the distribution of foraminiferal and ostracod assemblages and their environmental constraints in estuarine regions can represent the starting point for monitoring and environmental management and serve as the background for studies of sea level changes and Quaternary evolution of coastal regions. Muñoz et al (1995) used for the first time foraminiferal and ostracod assemblages to identify estuarine compartments by using only qualitative parameters in the Iberian Peninsula.…”

Laut et al (2012b) based on published works gave an overview of the main species that occur in the Guanabara Bay.…”
