Niche Diversification of Sphagnum in Bolivia

Abstract

Niche breadth values of Sphagnum species in the páramo and cloud forests of Bolivia are similar to those reported for Sphagnum-dominated peatlands in North America, but niche overlap values are higher for Sphagnum species in Bolivia. The pH, conductivity, and concentrations of Ca, Mg, Na, K, and P suggest that Sphagnum habitats in Bolivia are ombrotrophic in nature. Sphagnum is limited to small, scattered carpets in the páramo and cloud forests of the Bolivian Andes between 1800 and 4200 m. Common species found in these habitats include S. alegrense Warnst., S. boliviae Warnst., S. cuspidatum Ehrh., S. magellanicum Brid., S. oxyphyllum Warnst., S. recurvum P. Beauv., S. sanctojosephense Crum & Crosby, and S. sparsum Hampe.
