El objetivo del presente estudio fue de realizar un análisis comparativo de la diversidad florística, dominancia y patrones de distribución arbórea (DAP > 10 cm) de 21 parcelas permanentes de 1 ha en bosques de tierras bajas en la región Madre de Dios. Los datos fueron compilados de base de datos como RAINFOR, ForestPlots.net, entre otros. La composición florística fue analizada utilizando las variables de riqueza de especies, géneros y familias. Para el análisis estructural se calcularon los parámetros fitosociológicos de dominancia (área basal m2/ha), abundancia e índice de importancia para cada especie. Para agrupar las parcelas de los sitios de estudio en función a su composición florística se realizaron análisis de conglomerados jerárquicos y un Escalamiento Multidimensional no Métrico para representar en dimensión reducida los patrones de composición florís...

The rapid urban and agricultural expansion cause severe impacts on soil water infiltration capacity, but these effects have not yet been sufficiently investigated, especially in the Peruvian Amazon. The study aimed to analyze the variations in speed and soil infiltration in two vegetation cover types (primary intervened forest and pasture) in the Peruvian Amazon. The infiltration rate of the soil was measured using the single ring infiltrometer; three samples were collected in the pasture and six in the primary forest. With the values obtained, the infiltration curves were constructed. To evaluate differences in infiltration capacity between cover vegetation types, we used the t‑Student test. Our results show that the infiltration capacity in the primary forest was greater than in the pasture (p ≤ 0,01, t‑Student test). Regarding the physicochemical characteristics of the soil, we ...
