Summary 216 species of diatoms have been found epiphytic on common intertidal marine algae from Great Cumbrae Island, Firth of Clyde, Scotland. Green and red algae had larger epiphytic floras than brown algae. Cocconeis spp. (especially C. scutellum var. scutellum) were common and abundant, and the endophytic Navicula endophytica was found in large numbers in fucoid algae. Similar epiphytic floras were observed on Cladophora rupestris, Polysiphonia lanosa, Gigartina stellata, and Palmaria palmata, but that on Enteromorpha intestinalis was quite distinct. 相似文献

Summary Pollen analytical investigations are described from a site on the Pass of Drumochter in the central Grampian Highlands. Three pollen assemblage zones were identified in the profile which spans the mid- and late-Postglacial periods. The earliest vegetational record is of birch and hazel woodland, which was in turn succeeded by the establishment of pine forest, possibly around 7000 B.P. Declining arboreal pollen percentages and increased values for open-habitat taxa in the upper reaches of the profile reflect the impact of Neolithic man in the area, with the destruction of the forests, and the spread of dwarf shrub heath and heather moor across formerly wooded hillsides. 相似文献
