Characterization of abiotic conditions affecting vegetation distribution in the river Plate coastal plain, Argentina

Abstract: The river Plate coastal plain is located in northeastern Buenos Aires province, where geological events such as sea transgressions and regressions in the Holocene have produced a stratigraphic column with marine-estuarine, fluviatile and continental sediments, as well as a variety of landforms and soils. The aim of this paper is to describe these different coastal settings and their influence in the distribution of plant communities.

“…In turn, nitrate is a very scarce ion, appearing in all of the analysed samples in concentrations lower than mg/L. Given the presence of organic soils in the shell ridges (Giménez et al, 2008), the scarce nitrate content may be explained as a consequence of the decomposition of the soil organic matter (Canter, 1996).…”

“…Las precipitaciones se distribuyen a lo largo de todo el año, aunque una característica distintiva de la región es la alternancia periódica de inundaciones y sequías estivales (Vervoorst 1967;Burgos 1968). Los suelos tienen un desarrollo incipiente, con un horizonte A oscuro que se asienta sobre un horizonte de transición AC o directamente sobre la conchilla (Giménez et al 2008). El horizonte superficial de los talares presenta 20 a 30 cm de espesor, una textura franca a franco-arenosa, con un 12% de materia orgánica (Sánchez et al 1976).…”

Por otro lado se recurrió a publicaciones más recientes con el fin de enriquecer la caracterización de los suelos de planicie costera (Giménez et al, 2008, Martinez et al, 2006, Imbellone et al, 2012, Imbellone et al, 2014. Tabla 4.1: Listado de perforaciones realizadas mediante barreno manual con sus respectivas ubicaciones y profundidades.…”

“…Por otro lado, la llanura de marea relicta está ocupada por comunidades de pastizales halófilos: comunidad de Paspalum vaginatum, comunidad de Sporobolus indicus y comunidad de Bothriochloa laguroides y la comunidad de Hordeum pusillum (Cagnoni et al, 1996). En los canales de marea aparecen especies tales como Eryngium eburneum (carda) y Solanum glaucophyllum (duraznillo) (Giménez et al, 2008). Celtis ehrenbergiana (tala).…”
