The evaluation took place in July 2010, in the mangrove, raffia and forest associations. Four band transects (10 m x 3 m) were traced in each plant association, and two samples were taken out per day and two per night from each transect, using the method of intensive search.

Los anfibios y reptiles en zonas costeras presenta patrones de distribución y el número de individuos cambiantes, influenciados por factores ambientales físicos y químicos. El objetivo de este estudio fue caracterizar a la comunidad de herpetofauna de las asociaciones vegetales que rodean la Laguna de Gandoca, durante la época lluviosa. La evaluación se realizó en julio del 2010, en las asociaciones vegetales de manglar, yolillo y bosque. Se realizaron cuatro transectos en banda (50 m x 3 m) en cada asociación vegetal con dos muestreos diurnos y dos nocturnos, por transecto. Se utilizó el método de búsqueda intensiva de individuos, los cuales fueron capturados para su identificación. Se midieron la temperatura, la cobertura vegetal, la humedad del suelo y la profundidad de la hojarasca. Se determinaron la equidad, la diversidad y la dominancia de especies, y la heterogeneidad entre las asociaciones vegetales, utilizando el programa BioDiversity Pro and Richness 4. Se observó un total de 27 especies (en yolillal 18, en bosque 17 y en manglar 4). En el bosque se identificaron el mayor valor de equidad H = 2,47 y la menor dominancia d = 0.18. El bosque y el yolillal presentaron 0,63 de similitud. La cobertura vegetal que rodea la laguna de Gandoca presentaba una transición manglar-bosque bien establecido, con un área amplia de palmar pantanoso (yolillal), que se mezclaba con la vegetación del bosque y que explica la semejanza entre los valores de diversidad del yolillal y el bosque. Estas asociaciones ofrecían microhábitats y recursos a los reptiles y anfibios, mientras que el manglar ofrecía poco, pero era importante para especies con hábitos especializados como Tretanorhinus nigroluteus. 2018-06-29 2018-08-16T19:45:54Z 2018-08-16T19:45:54Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Artículo revisado por pares https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/3630 10.18845/tm.v31i2.3630 https://hdl.handle.net/2238/9901 spa https://revistas.tec.ac.cr/index.php/tec_marcha/article/view/3630/pdf Copyright (c) 2018 Revista Tecnología en Marcha application/pdf Editorial Tecnológica de Costa Rica Revista Tecnología en Marcha; Vol. 31, Núm. 2: Abril-Junio 2018; 127-135 2215-3241 0379-3982 |
