description	La conversión de los ecosistemas de bosque tropical a ecosistemas agro pastoriles y otros usos de la tierra continúa imparable en América Latina. El presente documento comprende un estudio comparativo en el cual se evaluó el grado de fragmentación del bosque durante un periodo de 23 años (entre 1973 y 1996) en dos áreas localizadas dentro de la misma región ecológica, pero en dos países (Colombia y Ecuador) que exhiben diferentes patrones de colonización antrópica. Se usaron índices de estructura del paisaje para evaluar el grado de fragmentación del bosque a ambos lados de la frontera internacional. Los resultados muestran que la extensión de la fragmentación del bosque ha sido considerablemente mayor en el lado colombiano, lo que sugiere que los ecosistemas naturales podrían estar sujetos a mayores presiones de degradación, con efectos perjudiciales potencialmente importantes sobre la abundancia y distribución de la biota.

The present document constitutes a comparative study in which the degree of forest fragmentation through a 23-year period (between 1973 and 1996) was evaluated in two areas located within the same ecological region, but in two different countries (Colombia and Ecuador) which exhibit different patterns of human colonization. Landscape structure rates were used to evaluate the degree of forest fragmentation at both sides of the international border. Results show that the extent of forest fragmentation has been considerably higher on the Colombian side, suggesting that the natural ecosystems might be subject to higher degradation pressures, with potentially important detrimental effects on the abundance and distribution of the biota.Boletín Científico2013-01-01T00:00:00Z2025-10-08T21:03:36Z2013-01-01T00:00:00Z2025-10-08T21:03:36Z2013-01-01Artículo de revistahttp://purl.org/coar/resource_type/c_6501Textinfo:eu-repo/semantics/articleJournal articleinfo:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1application/pdf0123-3068https://repositorio.ucaldas.edu.co/handle/ucaldas/230532462-8190https://revistasojs.ucaldas.edu.co/index.php/boletincientifico/article/view/4518https://revistasojs.ucaldas.edu.co/index.php/boletincientifico/article/view/4518eng6315317Boletín Científico Centro de Museos Museo de Historia NaturalANDRÉN, H., 1992.
