    Description: Los procesos costeros de diferente intensidad producen efectos sobre la línea de costa de cualquier región que de una u otra forma afectan su economía. El balance erosión-sedimentación de las playas se encuentra íntimamente ligado a la hidrodinámica del mar y a su interacción con la atmósfera, complementando de esta forma el sistema costa-mar-aire. En el presente documento se relacionan los principales resultados contenidos en el estudio de las características hidrodinámicas y geológicas del Golfo de Urabá, llevado a cabo entre 1988 y 1989 en cooperación con la Misión Técnica Francesa. Este estudio ha permitido identificar la formación de prismas de acrecimiento sedimentario principalmente en los alrededores de los deltas de los ríos Atrato y Turbo, así como definir las condiciones oceanográficas durante las épocas húmeda y media, además de determinar las características morfológicas del lecho marino.
    Description: The coastal process of different intensity are responsible of effects over the coast line in a region which in a way or another affect their economy. The erosion-deposition balance in the beaches is close related to the hidrodinamics of the sea and the interaction with the atmosphere, completing in this way the sistem coast-sea-air. Is this document a relatioship between the main results obtained in the study of the hidrodinamic and geological characteristics of the Gulf of Urabá is presented, carried out between 1988 and 1989 with the cooperation of the French Technical Mission. This study permited to identify the formation of sedimentary accresion prism mainly in the surroundings of the deltas of the Atrato and Turbo rivers, as to define the oceanographical conditions during the humid and dry seasons, and also determine the morphological characteristics of the marine bottom.

    Description: Morfológicamente la Plataforma Caribe colombiana en este sector se presenta relativamente estrecha y poco profunda, especialmente en el área cercana a la desembocadura del Río Magdalena donde alcanza los 12 mts. de profundidad. Esta cortada por 5 cañones de dirección estructural similar a las fallas Bolívar, Romeral, Santa Marta y Oca, lo cual indicaría una posible asociación de estos cañones a los sistemas de fallas. La sedimentación es esencialmente terrígena y su distribución sobre la plataforma está sujeta a la existencia del cañón del Magdalena, a los aportes del río y a su posterior repartición por las corrientes marinas lo cual explica la ausencia de un prisma sedimentario en esta zona.
    Description: Morphologically the Colombian Caribbean Platform in this sector is relatively narrow and shallow, specifically in the area near the mouth of the Magdalena river where reaches the 12 mts of depht. It is cut by 5 canyons structuraly similar to the Bolívar, Romeral, Santa Marta and Oca faults, indicating a possible association of this canyons to the fault sistem. The sedimentation is essentially terrigenous and its distribution over the platform is subject to the existance of the Magdalena canyon, to the river outfall and the effect of the marine current which explains the absence of a sedimentary prism in this area.

    Description: Este trabajo es una continuación del proyecto “Estudio Geológico e Hidrológico del Golfo de Urabá” realizado en cooperación con la misión técnica francesa a partir de 1988 con una duración de dos años. En las instalaciones del CIOH, a través del programa ANIM del Center National de Recherches Scientifiques (CNRS), se efectuó el procesamiento de una imagen SPOT capturada sobre el área en época media (febrero/89), con el fin de determinar la circulación de las aguas superficiales en el Golfo durante este tiempo usando como trazador las plumas turbias (distribución del material en suspensión) de los ríos que desembocan allí (Atrato, León, Turbo, etc.). En la Universidad de Bordeaux (1991) se realizó el tratamiento de esta imagen con el programa Pericolor para la visualización del contorno costero del Golfo y la incidencia del frente de olas en las proximidades de Bocatarena, con el propósito de analizar en esta última la disipación y concentración de la energía de la ola en este tramo de la costa. Los cambios morfológicos costeros (erosión-sedimentación) ocurridos en esta área en los últimos años se obtuvieron a partir de comparaciones de la línea de costa de las cartas náutica de 1938 y 1983 y del contorno costero de la imagen SPOT de 1989. Asimismo fue posible determinar las variaciones del fondo marino a través de comparaciones batimétricas de las cartas antes mencionadas. La circulación de las aguas superficiales en el Golfo se presenta en dos sentidos: N-S hacia el sector oeste, esto lo determina la dirección este-oeste con tendencia hacia el sur de las plumas turbia frente a la desembocadura del río Atrato, influenciadas por la acción de los vientos Alisios durante esta época (media) del año; y S-N en la zona oriental del Golfo donde las plumas turbias están afectadas hacia el norte y cargadas de abundante material en suspensión. La pérdida de grandes extensiones de costa, la formación de flechas litorales y el desarrollo de deltas han determinado importantes cambios morfológicos en la línea de costa del Golfo en los últimos años. A diferencia de la línea de costa donde predomina la erosión sobre la sedimentación, el fondo marino del Golfo, presenta una gran acumulación del sedimentos hacia la parte este y central del mismo, específicamente a la altura de Bahía Colombia.
    Description: This work is a results of project "Hydrologic and Geologic study of the Urabá Gulf" corried out jointly wfth the Technical French Mission from 1988, which hada two year duration. At the CIOH, trough the Centre Nationale de Recherche Scientffique (CNRS) ANIM program the proccessing of a SPOT lmage took place; this image was received on an area during the mean stage (February/89) in order to determine the surface water circulation in the Gulf during such time using a turbidity feather (distríbutíon of material in suspension) of rivers flowíng there (Atrato, León, Turbo, etc). At the Bordeaux Uníversity (1991) a treatment of this image with the Perico/ar program was done for visualing the Gulf shore contour and the incidence of the wave fronts on the Bocatarena surroundings of Atrato river, in arder to analíze about the latter the. energy depositíon and concentration of waves around this section of the coast. The coasta! morpholígical changes (eros ion -sedimentation) ocurred within this area during the last recent years were obtained starting from comparisons of shore fines from nautical charts of 1938 and 1983 and from SPOT lmage coastal contour of 1989. A/so, ft was possible to determine the sea bottom mareations through bathymetric comparisons of the abovementioned charts. The Gulf surf ace water circulation shows two directions: N.S. towards the west sector which determines the East -west direction with a tendíng towards the south ot turbidity feather in front ot the river A trato flowíng; influenced by the action of trade winds during the age (mean) of the year; and N -Son the Gulf west zone where the turbidfty feather are affected towards the north and are loaded with plenty of material in suspension. The loss of large extensions of shore, the formation of /ftoral drifts and the development of deltas have determined important morpho!ogícal changes on the Gulf shore líne in the recent years. Contrary to the shore fine where erosion is predomínant overs sedimentation the Gulf bottom presents a great sediment acumulation towards its own east and central part specifically at Bahía Colombia.

    Description: The riparian forest is one of the most diverse environments of the La Plata River plains. It is represented by patches of humid forests, which are a valuable source of ecosystem services and have recreational \nand educational potential. However, the riparian forest has undergone constant modification, worsened by private \nreal-estate developments and a lack of government regulation. Among the reserves that protect the riparian \nforest, the Municipal Ecological Reserve of Avellaneda is the closest to the southern limit of the Autonomous City \nof Buenos Aires. Although there are around 300 species of wild fauna and flora informally registered in the area, \nthere are only a few studies published about its biodiversity. In this work, the diversity of thirteen native and exotic \nferns in the core area (Eco \xc3\x81rea) of the reserve is characterized, the origin of the species is also evaluated and \ncomparisons are made with other nearby protected areas. The Eco \xc3\x81rea of the Reserve plays an important role as \npart of the urban reserve corridor of the La Plata River plains and constitutes a refuge for both native and exotic \nruderal species. The present work represents the basis for future studies about the population dynamics and the \ncolonization strategies of the ferns.

    Description: The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the Outline of Fungi and funguslike taxa, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the Outline of Fungi website (https://www.outlineoffungi.org/), and these will be finally published in the biannual edition of the Outline of Fungi and fungus-like taxa. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, ‘to promote a more stable taxonomy in Fusarium given the divergences over its generic delimitation’, or ‘are there too many genera in the Boletales?’ and even more importantly, ‘what should be done with the tremendously diverse ‘dark fungal taxa?’ There are undeniable differences in mycologists’ perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others’ work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa. Interested parties should contact the lead author if they would like to be involved in future outlines.
