dc.description.abstractLos bosques secos tropicales son ecosistemas complejos y frágiles con alta intervención antrópica y ciclos reproductivos restringidos. Albergan riqueza, diversidad estructural, fisiológica y fenológica únicas. Esta investigación se desarrolló en el valle del Alto Magdalena, en cuatro fragmentos de bosque con diferentes estados sucesionales. En cada fragmento se establecieron cuatro parcelas permanentes de 0.25 ha y se evaluó el hábitat lumínico asociado a la riqueza, abundancia relativa y rareza de especies, al igual que la dinámica del bosque que contempló mortalidad, reclutamiento y crecimiento diamétrico para un periodo de 5.25 años. En bosque ribereño maduro se encontró una riqueza de especies mayor a la reportada en otros estudios para áreas similares en el Valle del Cauca y la Costa Atlántica. Se evidencian valores de riqueza, heterogeneidad y rareza de especies mayores que los encontrados para zonas más secas del Tolima. La estructura, diversidad y dinámica del bosque se correlacionaron con el hábitat lumínico, mostrando diferencias en la arquitectura del dosel y su papel en la captura y absorción de radiación. Bosques con dosel denso presentan poca disponibilidad de radiación fotosintética activa en el sotobosque, relacionado con baja riqueza de especies, mientras que sotobosques iluminados son más ricos y heterogéneos.spa
dc.description.abstractTropical dry forests are complex and fragile ecosystems with high anthropic intervention and restricted reproductive cycles. These have unique richness, structural diversity, physiological and phenological . This research was executed  in the Upper Magdalena Valley, in four forest fragments with different successional stages. In each fragment four permanent plots of 0.25 ha were established and lighting habitat associated with richness, relative abundance and rarity of species. The forest dynamics included the mortality, recruitment and diameter growth for a period of 5.25 years. The species rischness found in the mature riparian forestis higher than that reported in other studies of similar areas in Valle del Cauca and the Atlantic coast.  The values of richness, diversity and rarity species are more evidenced  than the magnitudes found in  drier areas of Tolima. The structure, diversity and dynamics of forests were correlated with the lighting habitat, showing differences in canopy architecture and its role in the capture and absorption of radiation. Forests with dense canopy have limited availability of photosynthetically active radiation in understory related low species richness, while illuminated undergrowth are richer and heterogeneous.eng
