Abstract
Myxomycetes are a group of eukaryotic protists being studied extensively by mycologists, and it is generally believed that they are ubiquitous, like other terrestrial, free-living microorganisms. However, recent ecological studies have proved that various environmental gradients affect their distribution. Based on field works and examination of herbarium specimens, information of the geographical distribution of 52 taxa of Physarales in northern Taiwan are summerized. According to these locality records and fuzzily classified maps of various environmental parameters, a raster-based profile model is designed to predict their distribution in northern Taiwan. The results indicate the completeness of species diversity inventory is ca. 94-98%. The distribution patterns of the 52 taxa can be classified via hierarchical cluster analysis into (1) widely-distributed (8 taxa); (2) hilly-mountainous (10 taxa); (3) lowland (27 taxa); and (4) ill-defined (7 taxa). The predicted range map of each taxon can be regarded as a hypothesis of its ecological niche, and the model provide a chance to evaluate the bioclimatic importance of each collection locality. Using these information as reference, further biodiversity inventories and ecological studies would be more efficient.
