Aim: To quantify distribution patterns of vascular epiphytes and determine how climate gradients drive species turnover patterns of tropical montane cloud forest systems. Location: Volcán Maderas, Isla de Ometepe, Nicaragua. Methods Surveys were conducted in five distinct forest types as follows: Dry Forest, Humid Forest, Wet Forest, Cloud Forest, and Elfin Forest. Results: A hump-shaped distribution pattern was detected for all vascular epiphytes at approx.1000 m in elevation (Cloud Forest). Overall species turnover was high for vascular epiphytes along the elevation gradient and was mainly driven by water availability. In addition, changes in size of vascular epiphytes were detected. Main conclusions: Given the lowest dissimilarity recorded between the Wet and Cloud Forests, the shared species between these two forest types provide evidence for the source-sink hypothesis.
