  abstract = {{S}mall vertical variations in occurrences of mangrove foraminifera and arcellaceans (thecamoebians) provide a zonation scheme that is applicable to the study of short-term sea-level change. {S}ampling along transects was carried out at three sites in southern {B}razil and four sites along the {R}io de {J}aneiro lagoon system. {T}he {S}ai{G}ua 6 fluvial-estuarine point bar that divides the states of {S}anta {C}atarina and {P}arana, and the {C}apinzal and {V}eiga islands at the ancient flood tidal delta of the {G}uaratuba {B}ay, were sampled during two summers for a total of 42 samples. {I}n the state of {R}io de {J}aneiro, the seaward borders of the {U}russanga, {B}oqueirao and {F}ora lagoons, which comprise the incipient brackish mangroves of the {S}aquarema {L}agoon system, were sampled in both summer and winter for a total of 17 samples. {T}hree samples were collected during the summer at the freshwater marsh of {J}acarepia {L}ake. {T}hese coastal sedimentary environments differ in latitude, climate, physio-chemical conditions, vegetation, and sediment type. {A}ltitude, rate of sediment transport and salinity influence the distribution of three faunal zones: higher, middle, and lower. {S}tatistics on the dead foraminiferal distribution and ecological indications given by live occurrences showed that {H}aplophragmoides sp. is the dominant species at the uppermost stations (higher high water-{HHW}, with a 6cm vertical range) in both {G}uaratuba and {R}io de {J}aneiro transects, whereas {T}rochammina inflata dominates the southernmost {S}ai-{G}uacu site. {T}he {H}aplophragmoides-{T}rochammina association was also the most consistent in both dead and live {HHW} assemblages. {T}rochammina inflata and two forms of {T} macrescens were found to be salinity-sensitive {HHW} assemblages, as were {P}olysaccammina hyperhalina and {M}iliammina fusca in the {G}uaratuba intertidal zone. {I}n {S}aquarema, the intertidal zone is marked by {T} macrescens, and {C}entropyxis aculeata predominates in {J}acarepii. {T}he subtidal zone in {P}arana contains {A}renoparrella mexicana, {T}iphotrocha comprimata, {T}rochammina macrescens f. macrescens, and {D}ifflugia oblonga, whereas in {R}io de {J}aneiro, {T} macrescens f. polystoma predominates.},
