EVALUACIÓN DE PTERIDOFITAS EN BOSQUES DE LA ZONA RESERVADA ALLPAHUAYO - MISHANA Y SANTA ROSA, LORETO

Abstract

El presente estudio fue realizado en la Zona Reserva Allpahuayo - Mishana y en el poblado de Santa Rosa (km 26 y 60 respectivamente, de la carretera Iquitos-Nauta), con la finalidad de evaluar la población de pteridofitas en distintos tipos de bosque en el marco del curso “Uso de inventarios biológicos para revelar patrones de distribución geográfica de especies en la selva baja amazónica” organizado por el proyecto Diversidad Biológica de la Amazonía Peruana, Perú - Finlandia (BIODAMAZ), con el apoyo del Instituto de Investigaciones de laAmazonía Peruana (IIAP) y la Universidad Nacional de la Amazonía Peruana (UNAP). Fueron realizados inventarios en siete transectos de 200 x 5 m, divididos en ocho subunidades de 25 x 5 m. Las zonas de muestreo fueron seleccionadas subjetivamente para representar geológicamente distintas áreas. Se colectó pteridofitas hasta una altura de 2 m. Fueron establecidas relaciones entre la composición de especies en los transectos y la cantidad de materia orgánica por transecto. Las ordenaciones fueron visualizadas con la prueba de Mantel. Existe una correlación entre los cambios de grosor de materia orgánica y los cambios florísticos entre los transectos, pero con alto riesgo de error (r = 0.28, p = 0.11). En el caso del varillal húmedo, la correlación fue negativa (0.25), indicando que en este transecto no existe una relación entre materia orgánica y composición de especies de helechos.
