... macrescens and Miliammina fusca indicate lower salinities (<15 psu). Good indicators for higher salinities are Haplophragmoides wilberti (10–20 psu) and Arenoparrella mexicana (10–20 psu and 28–30 psu). Ammonia spp. prefer salinities >15 psu and Elphidium spp. >20 psu. Ammonia tepida , Helenina...

... and fine- to medium-grained sands. Biotope 1b is found in the mid-estuarine environment and has a maximum water depth of 4 m. It is distinguished by an abundance of Arenoparrella mexicana. Biotope 2 occurs within the subtidal lower estuarine environment with a maximum water depth of 4 m...

... was Arenoparrella mexicana . The most abundant species in the high marshes was Entzia macrescens . The upland–marsh transition zones were dominated by Trochamminita irregularis and Pseudothurammina limnetis . Canonical correspondence analysis was applied to assess the relationship between a priori defined biofacies...

... of variance (ANOVA) was used to investigate the differences in mean proportions for six species ( Miliammina fusca, Trochammina inflata, Arenoparrella mexicana, Tiphotrocha comprimata, Haplophragmoides wilberti and Jadammina macrescens ) selected because of their importance in distinguishing assemblages...

.... The mineralogical composition of the agglutinated grains in Trochammina inflata and Arenoparrella mexicana is very different from that of sediment; the composition of Jadammina macrescens is generally different from that of the sediment with some exceptions, and in Miliammina fusca , Paratrochammina haynesi...

... (SHECSI)] were limited to these. The low abundance of foraminifera along Transect C2 might be due to erosion opposite the jetty. Cluster analysis revealed three zones. Zone I, above 0.22 m above annual mean sea level (AMSL), is co-dominated by Arenoparrella mexicana and Trochammina inflata . Species...

... generally more likely to be preserved in the lower marsh than the higher marsh at low- and intermediate-salinity sites. The opposite pattern was evident at the high-salinity site but this may be due to the low numbers of deep infaunal specimens recovered. Arenoparrella mexicana, Haplophragmoides wilberti...

..., as were Polysaccammina hyperhalina and Miliammina fusca in the Guaratuba intertidal zone. In Saquarema, the intertidal zone is marked by T. macrescens, and Centropyxis aculeata predominates in Jacarepiá. The subtidal zone in Paraná contains Arenoparrella mexicana, Tiphotrocha comprimata, Trochammina...

... the high marsh lack these three low-marsh taxa. No foraminifera are distributed only within the high marsh. Those species that are common in the high marsh (Trochammina inflata, T. macrescens, Arenoparrella mexicana) occur throughout the marsh (high, transitional, and low) and, therefore, cannot serve...

...Fred B Phleger ABSTRACT The Foraminifera are grouped into three principal biofacies and one subfacies in the Mississippi Delta area. The following species are confined to the marsh facies. Ammoastuta inepta (Cushman and McCulloch) Arenoparrella mexicana (Kornfeld) Leptodermella variabilis Parker...
