Diversidad y riqueza de aves en diferentes hábitats en un paisaje fragmentado en Cañas, Costa Rica :

Richness, abundance and bird diversity were characterized in habitats with different tree cover (dry forest fragments, riparian forests, scrubs, live fences, low and high coverage pasturelands) in a fragmented landscape in Cañas, Costa Rica. Pastures with high tree cover and riparian forests presented higher richness of bird species than the dry forest fragments and pastures with low tree cover. Forest habitats presented a different bird composition than that registered in the open habitats, with more species of particular forest birds. Open habitats and pastures presented a simpler bird composition (common and abundant species) characteristic of agricultural systems.
