Un factor clave para generar políticas de conservación y de manejo de un área protegida es el conocimiento detallado de su biodiversidad. En este trabajo documentamos la flora vascular del Área Marina Costera Protegida Francisco Coloane representada por 55 familias, 92 géneros y 120 especies. De ellas 69 son endémicas para Chile y Argentina. Las familias más diversas son: Asteraceae (11 géneros/15 especies), Poaceae (10 /13) y Cyperaceae (6 /12). Los géneros mejor representados son Carex con 5 especies y Senecio con 4, mientras que 72 géneros están representados por una sola especie. La forma de vida dominante son las hierbas (74 especies, 62%), seguidas de los subarbustos (19 especies, 16%). Dos especies son nuevos registros para la Región de Magallanes... |

BACKGROUND: Twenty beavers Castor canadensis (Castoridae) were initially introduced in the Argentinean portion of Tierra del Fuego Island, from where they have occupied most of the Fuegian Archipelago and even reached the continent. This invasion is causing great damage to the subantarctic forest ecosystems, and it is not known how fast the species is spreading. While there is an estimation of this advance using interviews, it is not known how reliable these are and they cannot be made in remote areas. On the mainland, where beavers were present, their date of arrival was estimated using interviews and dendrochronology, and the dates obtained by both methods were compared for each site. RESULTS: Differences were found among the groups of respondents,... |
