Aplicación del LCA a la cadena productiva de muebles de Melina: Una opción para la competitividad sostenible de la Industria Forestal Costarricense

Introducción En los últimos años se ha llegado a un consenso mundial acerca de la necesidad de un desarrollo sostenible. Este hecho ha permitido contar con un cambio de perspectiva respecto del desarrollo, que se entiende como un proceso en el cual es necesario reconciliar aspectos económicos y sociales con las dimensiones biofísicas e los recursos naturales, y la capacidad del ecosistema para brindar servicios ambientales, para que la sociedad pueda continuar su proceso evolutivo…

Distribución espacial de Tinámidos (tinamiformes) en la Estación Biológica La Selva, Costa Rica (ING)

In the period from September to November 2003 I registered tinamids, using routes with variable radius through paths and transects of 200 m in four different habitats of La Selva Biological Station (10°25ʼ52.51"N, 84°00ʼ12.96"W). The objective of this study was to identify the sites that are frequent the most by the three different species of Tinamiformes of the area. I registered highest number of tinamous using transects of 200 m. Tinamus major was mainly found in primary forest, where it was very hard to observe, and in an abandoned agroforestry system, where it was very tolerant to the presence of humans. It was observed solitary or in group of up to five adult individuals. Crypturellus soui would concentrate more in areas that had an initial secondary growth, and was the specie most difficult to observe, it was registered as pairs and groups. Crypturellus boucardi is a uncommon specie, it was found solitary in different types of habitats.
