The distribution of Ulota crispa at a local scale in relation to both dispersal- and habitat-related factors



The distribution of Ulota crispa at a local scale in relation to both dispersal- and habitat-related factors



Lindbergia 24(2): 65-74



The distribution of a species occurring in patchy habitats is mainly dominated by its dispersal abilities, the time interval of patch availability, and the inter-patch distance. An increase in distance or a decrease in patch size will have a negative influence on the size of bryophyte populations. However, in this paper we show that when distances between discrete patches are small, the distribution of the species of interest is mainly determined by the suitability of the different substrate types present and their distribution. The habitat parameters (substrate type, tree diameter and tree density) potentially explain 48% of the distribution pattern for Ulota crispa in the study area, whereas dispersal-related parameters (spatial co-ordinates and again tree density) hold a potential explanation of 36%. Of this 29% is overlapping in potential explanation. The distribution of Ulota crispa sensu lato within this study area is correlated most with the distribution of Salix caprea, Po pulus tremula and Fraxinus excelsior, and to some extent with Sorbus aucuparia and Acer pseudoplatanus. Betula pubescens, a prominent species within the study area, is regarded as a poor substrate, although a number of U. crispa cushions grow on it. The source of these cushions is probably neighbouring trees with better substrate characteristics. The models concerning population viability in relation to patchiness must incorporate the dispersal ability of the species, the distribution of different substrates, the time interval of availability of the particular habitat, the suitability of the different substrate types, and a parameter describing the relation of these variables to changing scales both in time and space.
