Anthropogenic Edges, Treefall Gaps, and Fruit-Frugivore Interactions in a Neotropical Montane Forest

Abstract: JSTOR is a not-for-profit service that helps scholars, researchers, and students discover, use, and build upon a wide range of content in a trusted digital archive. We use information technology and tools to increase productivity and facilitate new forms of scholarship. For more information about JSTOR, please contact support@jstor.org.. Ecological Society of America is collaborating with JSTOR to digitize, preserve and extend access to Ecology.Abstract. In a montane tropical forest in southwestern Colombia, w… Show more

“…These changes are permanent, interrupt the process of species turnover in ecological succession, and increase the intensity of effects according to the pathway width. We expect that changes in the vegetation should also influence the resource availability and habitat use by the fauna (Restrepo et al 1999;Dewalt et al 2003;Watson et al 2004). Our study stresses the importance of assessing the trade-offs between the consequences for conservation and the necessities of management of Atlantic Forest protect areas crossed by different kinds of pathways.…”

“…Estas diferencias pueden estar asociadas con: 1) la mayor humedad y menor radiación solar en los estratos bajos (Freiberg, 1994), factores que al evitar la desecación favorecen el crecimiento y desarrollo de grupos como Drymonia, Gasteranthus y Columnea (Weber, 2004); 2) la mayor disponibilidad de sustratos en estratos bajos (Nieder, et al, 2000), que permite su rápida colonización; 3) los mecanismos de dispersión asociados con la polinización por colibríes (Amaya-Márquez, 1996, y el consumo de frutos por aves (Restrepo, et al, 1999), y 4) la dificultad de detección de las especies del dosel (Smith, 2008). Además, esta segregación vertical permite la coexistencia de diferentes especies de Columnea al presentar estrategias de polinización contrastantes (Stiles,1981;Ackerman, 1986), como son un mayor número de flores en las especies del dosel, una alta sincronía de la floración, un sistema autocompatible y su asociación con colibríes no ermitaños; en comparación con las especies del sotobosque, que presentan una baja intensidad de la floración, tienden a ser polinizadas por colibríes ermitaños y presentan un sistema principalmente autoincompatible (Marín-Gómez, observación personal).…”

“…Swaine (Lindh, 2008) sehingga mempercepat dihasilkannya buah. Selain itu, Restrepo et al (1999) menemukan bahwa jumlah buah yang dihasilkan oleh areal rumpang (gap) lebih tinggi dibandingkan areal hutan yang memiliki kanopi yang rapat. Areal rumpang juga memiliki jumlah jenis tumbuhan penghasil buah yang lebih banyak dibandingkan areal hutan berusia tua.…”
