Description: This article discusses biodiversity conservation and implementation of sustainable development in southernmost South America and the new biosphere reserve in Cape Horn, located in Antarctica Chilena Province.

Description: This article discusses field environmental philosophy and biocultural conservation. Abstract: Habitats (where we live), habits (how we live), and inhabitants (who we are) constitute an ecosystem unit. The biosphere is composed of a reticulate mosaic of these habitat-habit-inhabitant units, where humans (with their indigenous languages, ecological knowledge, and practices) have coevolved. Today, these diverse ecosystem units are being violently destroyed by the imposition of a single global colonial cultural model. In Cape Horn at the southern end of the Americas, educators, authorities, and decision makers do not know about the native habitats, language, and flora, and do not distinguish between Cape Horn's flora and the flora that grows in other parts of the country or the world. In contrast, indigenous people and old residents have a detailed knowledge, but they do not participate in education, and decision making. It is not Homo Sapiens in general, but bioculturally biased educators, authorities, and decision makers who need to be transformed into (educated and responsible) members and citizen of biocultural communities. The Omora Ethnobotanical Park educational program was launched to contribute to a biocultural citizenship involving three critical steps: (1) the disclosing of biocultural diversity with a "fine filter" approach that permits understanding ...

Description: This article discusses Cape Horn, a National park free from alien species in southernmost South America. The Cape Horn Archipelago, tam- also called Wollaston archipelago, retains its pristine condition, almost completely free of exotic plant species.

Description: This article discusses the diet of the American mink Mustela vison. Abstract: Invasive exotic species of mammalian predators represent a major cause of vertebrate animal extinctions on islands, particularly those that lack native mammalian carnivores. In 2001, the American mink (Mustela vison) was recorded for the first time on Navarino Island, in the Cape Horn Biosphere Reserve (55° S) in Chile, representing the southernmost population of mink worldwide. In order to assess its potential impact on native fauna, the authors studied its diet on Navarino Island, as part of an integrative management program on invasive species. Over a three-year period (2005-2007) the authors collected 512 scats in semi-aquatic habitats: marine coasts, riparian and lake shores. Overall, the main prey was mammals (37% biomass), and birds (36%), followed by fish (24%). Over the spring and summer, mink consumed significantly more birds, whereas mammals constituted the main prey over the autumn and winter when migratory birds had left the area. Among birds, the mink preyed mainly on adult Passeriformes, followed by Anseriformes and Pelecaniformes, caught as chicks. Among mammals, the exotic muskrat (Ondatra zibethicus) was the most important prey, and together with the native rodent Abrothrix xanthorhinus it accounted for 78% of ...

Description: This article is in a special issue of Environmental Ethics based on the workshop "Integrating Ecological Sciences and Environmental Ethics: New Approaches to Understanding and Conserving Frontier Ecosystems," held in the temperate sub-Antarctic region of southern Chile, in March 2007. The workshop was jointly organized by the Department of Philosophy and Religion Studies of the University of North Texas (UNT) and the Institute of Ecology and Biodiversity (IEB-Chile), in collaboration with the Center for Environmental Philosophy, and followed a three-week field graduate course, "Conservation and Society: Biocultural Diversity and Environmental Ethics," involving graduate students from the U.S. and Latin America. These events built on a decade of collaboration between UNT environmental philosophers and Chilean ecologists, and were followed by two symposia held subsequently at two annual meetings of the Ecological Society of America (2007 and 2008).
