Didymosphenia geminata GIS Patagonia Argentina distribution Didymosphenia geminata SIG Patagonia Argentina distribución Background and aims: Didymosphenia geminata is a freshwater diatom that forms dense soggy carpet-like layers lining the bottom of aquatic environments. In Argentina the Secretaría de Ambiente y Desarrollo Sustentable de la Nación declared it exotic invader species. In the lasts 9 years it has colonized rivers from Patagonia and its distribution in the region has considerably widen. The aim of this paper is to analyze the dynamic of this species invasion in Argentinean Patagonia through the use of Geographic Information Systems (GIS).M&M: the analyzed data were obtained by our team in Neuquén and Chubut provinces and also from technical reports published by universities or governmental institutions in websites. A database at regional scale from Neuquén to Tierra del Fuego was built considering presence-absence data, geographic position and dates and in some cases environmental data (pH, conductivity, etc.) Results: the results were incorporated to a GIS using Q-Gis 2.14 an open source and free software that allowed us to generate distribution maps at national and provincial level.Conclusions: the available data show that D. geminata has widen its distribution since 2010 to present from Chubut province to the north reaching Neuquén province and to the south up to Tierra del Fuego province. Introducción y objetivos: Didymosphenia geminata, diatomea declarada “Especie Exótica Invasora” en Argentina por la Secr. Ambiente y Desarrollo Sustentable de la Nación. Esta especie coloniza rocas y puede formar grandes matas mucilaginosas que cubren el lecho de los ríos, ocasionando un considerable impacto estético y provocando serias alteraciones en los ecosistemas. En los últimos 9 años la especie ha colonizado ríos andino-patagónicos y ha aumentado considerablemente su distribución en la región. El objetivo de este trabajo es analizar la dinámica de esta especie en la Patagonia argentina mediante el uso de SIG.M&M: los datos provienen de resultados obtenidos por el grupo de trabajo en las provincias del Neuquén y del Chubut e información abierta y libre disponible en la web. Se generó una base de datos a escala regional abarcando desde Neuquén a Tierra del Fuego.Resultados: fueron incorporados a un SIG, lo que permitió generar mapas de distribución a nivel provincial y nacional. Conclusiones: los datos disponibles hasta marzo de 2018 muestran que D. geminata, ha expandido su distribución entre 2010 y 2018 desde la provincia del Chubut hacia el norte alcanzando la provincia de Neuquén y hacia el sur llegando a Tierra del Fuego.     Sociedad Argentina de Botánica 2019-06-20 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo original application/pdf text/html https://revistas.unc.edu.ar/index.php/BSAB/article/view/24362 10.31055/1851.2372.v54.n2.24362 Boletín de la Sociedad Argentina de Botánica (Journal of the Argentine Botanical Society; Vol. 54 No. 2 (2019): June; 169-183 Boletín de la Sociedad Argentina de Botánica; Vol. 54 Núm. 2 (2019): Junio; 169-183 Boletín de la Sociedad Argentina de Botánica; v. 54 n. 2 (2019): Junio; 169-183 1851-2372 0373-580X 10.31055/1851.2372.v54.n2 spa https://revistas.unc.edu.ar/index.php/BSAB/article/view/24362/23692 https://revistas.unc.edu.ar/index.php/BSAB/article/view/24362/27445 Derechos de autor 2019 Boletín de la Sociedad Argentina de Botánica
