    Description: El huracán Irma azotó la cayería noreste de Villa Clara el nueve de septiembre de 2017. La extensión de la región y la inaccesibilidad a muchos sitios de su geografía impidieron una valoración precisa de las afectaciones territoriales en el corto plazo. La percepción remota y el procesamiento de imágenes empleando QGIS, suministran las herramientas necesarias para la estimación de las mismas en nuestra investigación. Se determinó la dis- tribución actual de los hábitats naturales, y se seleccionaron las principales coberturas ve- getales como objeto de estudio. Con el uso del índice de vegetación normalizada (NDVI) se estima la degradación-resiliencia en el periodo 2016-2021. Los procesos de defoliación y rebrote constituyen las señales básicas en estas evaluaciones. Las afectaciones severas del huracán se estiman sobre el 82% del manglar (M), el 50% del bosque siempreverde micró- filo (BSV) y 29% del matorral xeromorfo (MX). El BSV y el MX mostraron una recu- peración muy veloz, en comparación con el M. La dominancia de Rhizophora mangle en este hábitat afectado resulta determinante en la retardada resiliencia. El 58% de manglar recuperado a los 3.6 años del huracán sugiere planificar estrategias de restauración en los sitios críticos identificados.
    Description: Hurricane Irma hit the northeast keys of Villa Clara on September 9, 2017. The vast region and the inaccessibility to many places of its geography, prevented an accurate assessment of the effects on the territory. Remote sensing and image processing using QGIS provide the necessary tools for image estimation in our research. The current distribution of natural habitats was determined, selecting the main plant covers as the object of study.With the use of the normalized difference vegetation index (NDVI) the degradation-resilience is estimated in the pe- riod 2016-2021. The processes of defoliation and regrowth are the basic signals in these evaluations. The severe effects of the hurricane are estimated at 82% of the mangrove (M), 50% of the dry evergreen forest (BSV) and 29% of the xe- romorphic scrub (MX). The BSV and MX showed a very fast recovery, compared to the M. The dominance of Rhi- zophora mangle in this affected habitat is decisive in the deayed resilience. 58% of mangroves recovered 3.6 years after the hurricane suggest planning restoration strategies at the identified critical sites.

    Description: Se señala la presencia en Cuba de la especie marina invasora Unomia stolonifera, introducida en Venezuela, de donde debe haber llegado a Cuba. Esta especie representa un peligro para los arrecifes coralinos de Cuba y del resto del Mar Caribe. Se describen las acciones realizadas para su erradicación.
    Description: The presence in Cuba of the invasive marine species Unomia stolonifera, introduced in Venezuela, from where it maybe has arrived in Cuba and which represents a danger to the coral reefs of Cuba and the rest of the Caribbean Sea, is noted. The actions carried out for its eradication are described.
