The bryophytic flora has been widely studied in Atlantic coastal dune environments while bryological literature addressing the Mediterranean bryophytes is still scarce and fragmented, although they are an important component of this area, especially considering their ability to colonize and stabilize sandy soils. The aims of this study were: (i) to analyze the taxonomy, chorology and ecology of coastal dunes bryoflora; (ii) to analyze distribution patterns of bryophytic species along a coastal dune vegetation zonation.

A total of 20 bryophytic species were detected most of which were acrocarpous mosses and, to a lesser extent, pleurocarpous and liverworts. Most bryophytes are pioneer colonizers, reflecting their adaptation to environments with high levels of stress/disturbance conditions such as those of coastal dunes. Finally, in this study we described for the first time how bryophytic species are distributed along a Mediterranean coastal dune vegetation zonation, focusing also on their chorological and ecological characteristics and on how they seem to follow the sea-land gradient, probably in response to different environmental conditions developing along this gradient.

Abstract

The bryophytic flora has been widely studied in Atlantic coastal dune environments while bryological literature addressing the Mediterranean bryophytes is still scarce and fragmented, although they are an important component of this area, especially considering their ability to colonize and stabilize sandy soils. The aims of this study were: (i) to analyze the taxonomy, chorology and ecology of coastal dunes bryoflora; (ii) to analyze distribution patterns of bryophytic species along a coastal dune vegetation zonation. We used as coastal dune model system a particularly well-preserved study area of the Sardinian coast (Italy), which includes several habitats listed in European Habitats Directive 92/43/EEC. We conducted a general survey of the area and a random sampling. A total of 20 bryophytic species were detected most of which were acrocarpous mosses and, to a lesser extent, pleurocarpous and liverworts. Most bryophytes are pioneer colonizers, reflecting their adaptation to environments with high levels of stress/disturbance conditions such as those of coastal dunes. Finally, in this study we described for the first time how bryophytic species are distributed along a Mediterranean coastal dune vegetation zonation, focusing also on their chorological and ecological characteristics and on how they seem to follow the sea-land gradient, probably in response to different environmental conditions developing along this gradient.
