          Abstract

          El presente estudio tuvo como finalidad conocer el aprovechamiento de los recursos maderables tropicales nativos por parte de la comunidad Emilio Rabasa, ubicada en la Reserva de la Biosfera Selva El Ocote, en el estado de Chiapas, México. Se realizaron encuestas semiestructuradas a 30 ejidatarios y se colectaron ejemplares para la identificación de las especies. Se determinó un total de 35 especies maderables nativas, incluidas en 31 géneros y 24 familias. Las principales especies maderables multipropósito mencionadas fueron el bojón (Corda alliodora (R. & P.) Oken), el palo amarillo (Terminalia obovata (R. & P.) Steud) la caoba (Swietenia macrophylla G. King), el jolocín (Heliocarpus donnell-smithii Rose), el cedro (Cedrela odorata M. Roem. King) y el copalchi (Croton guatemalensis Lotsy). Entre los principales usos que la comunidad le da a las especies maderables está, 38% la extracción de leña y postes para cercado, 17% para la elaboración de herramientas de trabajo y 16% para la elaboración de muebles, construcción y reparación de casas.

          This study aimed to identify the use of native tropical timber resources in the Emilio Rabasa community located in the Ocote Forest Biosphere Reserve, in Chiapas state, Mexico. 30 semi-structured surveys were conducted with ejidatarios "land-owners", and several specimens were collected for their identification. A total of 35 native timber species were determined, included in 31 genera and 24 families.The main multipurpose timber species mentioned were bojón (Cordia alliodora (R. & P.) Oken), palo amarillo (Terminalia obovata (R. & P.) Steud), mahogany (Swietenia macrophylla G. King), the jolocín (Heliocarpus donnell-smithii Rose), cedar (Cedrela odorata M. Roem. King) and copalchi (Croton guatemalensis Lotsy). Among the main uses that the community gives these timber species are 38% for extraction of firewood and fence posts, 17% for making tools and 16% for making furniture, construction and houses repair.

            Wilderness and biodiversity conservation.

            Human pressure threatens many species and ecosystems, so conservation efforts necessarily prioritize saving them. However, conservation should clearly be proactive wherever possible. In this article, we assess the biodiversity conservation value, and specifically the irreplaceability in terms of species endemism, of those of the planet's ecosystems that remain intact. We find that 24 wilderness areas, all > or = 1 million hectares, are > or = 70% intact and have human densities of less than or equal to five people per km2. This wilderness covers 44% of all land but is inhabited by only 3% of people. Given this sparse population, wilderness conservation is cost-effective, especially if ecosystem service value is incorporated. Soberingly, however, most wilderness is not speciose: only 18% of plants and 10% of terrestrial vertebrates are endemic to individual wildernesses, the majority restricted to Amazonia, Congo, New Guinea, the Miombo-Mopane woodlands, and the North American deserts. Global conservation strategy must target these five wildernesses while continuing to prioritize threatened biodiversity hotspots.

              A globally consistent richness-climate relationship for angiosperms.

              Species richness, the simplest index of biodiversity, varies greatly over broad spatial scales. Richness-climate relationships often account for >80% of the spatial variance in richness. However, it has been suggested that richness-climate relationships differ significantly among geographic regions and that there is no globally consistent relationship. This study investigated the global patterns of species and family richness of angiosperms in relation to climate. We found that models relating angiosperm richness to mean annual temperature, annual water deficit, and their interaction or models relating richness to annual potential evapotranspiration and water deficit are both globally consistent and very strong and are independent of the diverse evolutionary histories and functional assemblages of plants in different parts of the world. Thus, effects of other factors such as evolutionary history, postglacial dispersal, soil nutrients, topography, or other climatic variables either must be quite minor over broad scales (because there is little residual variation left to explain) or they must be strongly collinear with global patterns of climate. The correlations shown here must be predicted by any successful hypothesis of mechanisms controlling richness patterns.
