Diversidad arbórea a diferentes niveles de altitud en la región de El Salto, Durango

Abstract

La presencia de especies vegetales está en función de la altitud, por lo que, el propósito de este estudio fue estimar y comparar la diversidad arbórea sobre un gradiente altitudinal entre los 1 500 a los 3 000 m de la región de El Salto, Durango, que fue dividido en cinco intervalos de 300 m cada uno. Se seleccionaron doce comunidades forestales, y se ubicaron 268 sitios circulares de 0.1 ha de manera aleatoria, distribuidos de forma proporcional por cada intervalo, dentro del cual se estimó la riqueza de especies (S), los índices de diversidad proporcional de Shannon-Wiener (H’) y Simpson (l), los de equidad de Pielou (J’) y de dominancia de Simpson (El). La comparación de la diversidad arbórea entre altitudes se hizo sobre el índice de Shannon-Wiener mediante la prueba de t de Hutcheson. La riqueza de especies varió de 14 a 25 taxa, el índice de Shannon de 1.94 a 2.67 y el de Simpson de 0.09 a 0.18. Los de equidad y dominancia de Pielou y Simpson sugieren que la abundancia de las especies tiende a ser heterogénea. La prueba de t de Hutcheson demostró que existen diferencias significativas en la diversidad de especies entre los intervalos altitudinales.
