    FLORISTIC-STRUCTURAL DESCRIPTION OF THE PHYSIONOMIES DOMINATED BY TREES IN THE lNTEGRAL RESERVE OF PUNTA LARA (PCIA. DE BUENOS AIRES, REPÚBLICA.ARGENTINA). by Dascanio, Liliana M., Ricci, Susana E.

    Published 2023
    “…Thoseunits are; marginal or alluvial forest, old and young "ligustro" forest with totalbasal areas of 30.78 m2/ha, 28.71 m2/ha and 20.13 m2/ha respectively.The marginal forest is a subelimax community, with subtropical species,invade<! in some areas by the exotic Ligustrum lucidum that gives place toyoung and old "ligustro" forest.This marginal forest dwells the narrow and discontinuous band of naturallevee and is ecologically dependent on the river "albardon" interr lationship dueto pulsatil floods with its export-import of water, inorganic and organic dissolvedand suspended matter that constitutes part of the energy signature of the riveTineecosystem.The road parallel to tbe beach between forest and river, and artificial drainageobviously modified the frequency, intensity and duration of flood events,affecting hydrologic, chemical and physical variables of the natural forest environment.Tbe introduction of Ligustrum ltwidum some decades ago (Cabrera,1944) added a biological element of disturbance that is now naturalized andsuccesfully competes with native tree species mainly in those places were theterrain is less subject to flooding because of man-made structures.The importance of the trees (0.1 m DBH) in the alluvial fore t is sometimesgiven by size and density (Pouteria salidfolia: relative basal area 30 %, density2111ha), rnainIy by size (Ocotea acutífolia: relative basal area 12 %, density29/ha), or only by density (ex. …”

    ROSAS TRANSPLANTADAS Y EL MITO DE ELDORADO. TRAVESÍAS EN EL TIEMPO, EN EL ESPACIO, EN LA IMÁGEN Y EN EL SILENCIO / Translocated roses or the myth of Eldorado: Journeys through time... by Jelin, Elizabeth

    Published 2009
    “…Todo esto es lo dicho; también hay muchos silencios que deben ser develados.El caso de Eldorado será usado para plantear algunas reflexiones y preguntas sobre temas más generales de la investigación social: la conceptualización de la relación entre lo local y lo global, entre centro y periferia; la separaciónentre lo privado y lo público; la divisoria que establecemos entre racionalidad y objetividad por un lado, y las pasiones y emociones por el otro; el vínculo entre la investigación académica y los compromisos intelectuales; quizás algo sobre circunstancias y coincidencias en los procesos de plantear preguntas de investigación.Palabras claves: Eldorado, Misiones, local-global, nazismo, familia, inmigración, investigación social reflexiva.AbstractThe looking glass is directed towards Eldorado, a virgin subtropical land in Northeastern Argentina, around 1920. …”
