Abstract
This is the first survey of bryophyte diversity in the mangroves of Panama. The study was done in the mangroves of Bocas del Toro Province, Panama, in September 2016 and, July, May and August 2017. Bryophytes were collected from prop or stilt roots of mangroves, the mid-lower part of the trunks and the lower branches. In areas inundated at high tide, additional samples were collected on the cortex of palms, its rootlets, other angiosperm trees and from decomposing logs. Twenty-six species of liverworts and seven of mosses were identified. The most diverse and predominant liverwort family was the Lejeuneaceae with twenty-two species and two varieties and, among the mosses, the Calymperaceae with three species. Species affinities with other tropical mangroves were analyzed and liverworts were found to be the dominant element. Among the liverworts collected, two are new reports for Panama: Ceratolejeunea confusa and Frullanoides mexicana. Additional surveys of the cryptogamic vegetation of Panamanian mangroves are urgently needed due to the accelerated deforestation caused by anthropic activities and the potential loss of important biodiversity.
