Abstract

Biodiversity in much of the Neotropics is impacted by windward/leeward effects. North East trade winds dump moisture as they hit the mountains, creating a wetter Atlantic slope, and a drier more seasonal Pacific slope. These factors often favor higher biodiversity for a given taxon on the Atlantic slope. Fungi were collected between the two slopes of the Monteverde Cloud Forest. A total of 130 fungi specimens were collected from 1550 meters on both slopes of the Continental Divide to 1750 m. As predicted, fungal species richness (Pacific = 24 species, Atlantic = 39 species), abundance (Pacific = 40, Atlantic = 90), and diversity (H’ Pacific = 1.55, H’ Atlantic = 3.44) were significantly higher on the Atlantic slope than on the Pacific. It was also found that the two slopes, though in close proximity, have almost entirely different fungal communities. The results indicate that the climatic factors of high precipitation and lower seasonality caused by windward/leeward effects greatly effect fungal species diversity and composition.

Resumen

La biodiversidad en la mayoría de los neotrópicos es afectada por los efectos de la dirección de los vientos. Los vientos del este depositan la humedad en las montañas del atlántico, creando un atlántico más húmedo y un pacífico estacional más seco. Estos factores a menudo favorecen una mayor biodiversidad a un determinado taxón en la vertiente atlántica. Colecté hongos en las dos vertientes del bosque nuboso de Monteverde, Costa Rica. Un total de 130 hongos fueron encontrados en los trayectos entre los 1550 y 1750 metros. Como era de esperarse la riqueza de especies de hongos fue mayor en el atlántico (Pacífico=24 especies, Atlántico=39) al igual que la abundancia (Pacífico = 40, Atlántico =90) y la diversidad (H’ Pacífico=1.55, H’ Atlántico=3.44). También se encontró que a pesar de la proximidad de los sitios, tienen dos comunidades muy distintas de hongos. Los resultados indican que los factores climáticos como la precipitación y la estacionalidad afectan la composición de las comunidades de hongos.
