    Alfredo Lla帽a Gar铆n, Profesor de Estado en Ciencias Biol贸gicas y Qu铆mica de la Universidad de Chile (1937), es el precursor del estudio de las algas marinas en Chile. Esta rese帽a recuerda sus inicios, su pionera investigaci贸n en bot谩nica y trabajos en microalgas en aguas l铆mnicas, su contribuci贸n para el desarrollo de la Estaci贸n de Biolog铆a Marina de Montemar, Universidad de Chile y tambi茅n por 20 a帽os en la Universidad de Panam谩. El Prof. Lla帽a estudia, asimismo, las macroalgas marinas robusteciendo la importancia de su valor comercial. En la actualidad, Chile es reconocido como uno de lo m谩s importante proveedores de algas marinas para la extracci贸n de agar, carragenanos y alginatos, esenciales para la industria alimentaria, cosm茅tica, y biom茅dica

    A partir de 1985 comienzan los esfuerzos del Estado de Chile, con el apoyo de especialistas, para generar listas de especies de plantas (1985) y animales (1987) con altos a moderados riesgos de extinci贸n en el corto plazo producto de actividades antr贸picas (i.e., especies amenazadas). Las siete categor铆as de amenazas utilizadas para la fauna coinciden con las empleadas por la Uni贸n Internacional para la Conservaci贸n de la Naturaleza (UICN) en 1982; para la flora hubo coincidencia en solo cinco de las categor铆as utilizadas. En el a帽o 1994, la Ley 19300 de Bases del Medio Ambiente estableci贸 seis categor铆as de estados de conservaci贸n. El Reglamento para la Clasificaci贸n de Especies Silvestres, promulgado el 2005, defini贸 estas seis categor铆as haciendo una combinaci贸n entre lo propuesto por la UICN en 2001 y 1982. La generaci贸n de este sistema h铆brido que no era comparable con el utilizado ampliamente en el mundo, restringi贸 severamente la posibilidad de clasificar a las especies con amenaza inferior al nivel de Vulnerable. Complicaciones adicionales se generaron con la inclusi贸n de categor铆as de conservaci贸n en la Ley 19473 de Caza (1996), la Ley 20283 sobre Recuperaci贸n del Bosque Nativo y Fomento Forestal (2008), y sus respectivos reglamentos. La Ley 20417 (publicada el 26 de enero 2010) modific贸 la ley 19300 e incorpor贸 las categor铆as recomendadas por la UICN. Ahora el Estado requiere adecuar varios cuerpos legales para avanzar en el conocimiento del estado de conservaci贸n de la flora y la fauna nacional, y consecuentemente, asegurar la implementaci贸n de medidas efectivas de protecci贸n de la biodiversidad.<br>Since 1985, the Chilean government with the participation and support of different specialists in plant and animal conservation, started the publication of checklists (i.e. red books) of plant (1985) and animal species (1987) with high to mod茅rate risk of extinction due to human activities (i.e. threatened species). The seven categories of threats used in these publications matched those used by the International Uni贸n for the Conservation of Nature (IUCN) in 1982; nonetheless, for the flora there was matching only in five of the categories used. In 1994, the Law 19300 on the General Bases of the Environment established six categories of conservation status. The regulations for the classification of the wild species in Conservation categories, enacted in 2005, defined these six categories, which resulted from a combination of those proposed by the IUCN in 2001 and 1982. The generation of this hybrid system, which is not fully comparable with that of the IUCN (2001) and widely used in the rest of the world, has severely restricted the possibility of classifying species with a threat level lower than "Vulnerable". Further complications were generated due to the definition of conservation categories that appeared in the Laws 19473 (1996) regulating the hunting activity and 20283 (2008) supporting the native forest recovery and forestry development. The Law 20417 (enacted in January 26, 2010) modified the Law 19300 and incorporated the categories recommended by IUCN. Currently, the State requires adapting several legal bodies to advance in the knowledge of the conservation status of the nation's flora and fauna, and consequently, ensure the implementation of effective efforts to protect our biodiversity
