Vegetational structure of exposed dolomitic cliffs in the driftless region of northwest Illinois was quantified from 186 quadrats on five cliffs. All cliffs were sparsely vegetated, with a total of 41 species (14 lichen and 27 vascular) recorded in the upper 6 m. On all cliffs, cover averaged 16.03%, with lichen contributing 10.23% cover and vascular vegetation 5.80% cover. Seventy percent of all vegetation grew within 3 m of the cliff top. Linear regression indicated that both cover and density of vascular, but not lichen, flora increased with increased fracturing and decreased with distance

Exposed cliffs in the northern Swiss Jura Mountains harbour a highly diverse flora with numerous endangered and relic plant species. On these cliffs, sport climbing is enjoying increasing popularity. We examined the ecological effects of sport climbing on vascular plants at the cliff base and on the cliff face by assessing plant cover and species density at various distances from frequently used climbing routes. Plant cover was significantly reduced at the base of climbing routes. Furthermore, species density (number of species per square metre) at the cliff base, as well as plant cover and sp

The limestone cliffs of the Jura mountains in northwestern Switzerland harbour a diverse flora with several relic populations of arctic-alpine and Mediterranean plant species. Overgrowing forests increasingly threaten rare, relic plant species with high light demands on cliffs, because traditional forms of forest use, including the collection of firewood and grazing by goats, were abandoned. We examined the temporal and spatial patterns of overgrowing forest at six cliffs in the northwestern Swiss Jura mountains by analysing tree cover on time-series air photographs made between 1951 and 2000.

It has been found that in the territories of the Karakalpak Ustyurt (Uzbekistan), there are at least 497 species belonging to 244 genera and 54 families. The basis of the forage flora of the research area is represented by representatives of the families Amaranthaceae (80 species), Asteraceae (77), Poaceae (58), Brassicaceae (55), Fabaceae (34), Boraginaceae (33), Apiaceae (16), Caryophyllaceae (14), and Polygonaceae (11), characteristic of the flora of the Turan province. The role of herbaceous plants is high in the composition of pasture vegetation -they make up about 60% of the forage plant

Cliffs are among the environments with the most adverse conditions for living organisms because of the limited availability of soil, moisture, and nutrients, and owing to the harsh conditions of exposure. They constitute shelters for rare, endemic, and range-restricted plant taxa. A main database has been prepared which includes vascular plant taxa that are obligate or facultative chasmophytes and also contains information about their life form, chorology, protection status, occurrence in more than 135 places such as cliffs, gorges, or open rocky habitats, and their geographical distribution i

Coastal cliffs are important in plant ecology as a unique frontier between terrestrial and marine ecosystems. This study piloted close-range photogrammetry with an unmanned aerial vehicle (UAV) to clarify floristic patterns using 26 inaccessible coastal cliffs in a warm-temperate, preserved island (area: 6.5 km2). UAV-based flora data were analyzed in terms of cliff aspect (Type-N: northwestern aspect of the island, Type-S: other island aspects) and elevation. The studied coastal cliffs contained 94 flora taxa, of which 13 and 12 taxa were found from either Type-N or Type-S cliffs only. Type-S

This thesis investigates opportunities, challenges and limitations for plant ecological research in the context of Mediterranean cliffs. In particular, chasmophytic species, whose natural habitats are very steep, limestone mountain slopes in the proximity of the sea, in the Central and Western part of the Mediterranean area are considered as study objects. Studies were carried out in the coastal mountain belts of both North-western Sicily and Dianic coasts in the Valencian Community (Spain).

The vertical cliff-face habitat is renowned for many specifically adapted plant species that exhibit a high degree of local endemism. Over a period of nine years the succulents and bulbous succulents on cliff faces in South Africa and Namibia were systematically surveyed and documented. Distinction was made between succulents growing on cliffs as part of a wider habitat and those found only on cliffs (obligate cremnophytes). Most major cliff-face habitats in the study area were visited and all plants were documented. A check list and descriptions (including adaptive traits) of the 220 obligate

This chapter deals with the general features of plant diversity and distribution on the Sea of Cortés islands and to a lesser extent with adaptive features of plants such as morphology and phenology. This review is based mainly on the plant lists in appendixes 4.1-4.5 describing the island floras, endemics, and relicts. In our interpretations of these lists we draw from various floristic, systematic, and distributional works that pertain to the Gulf of California region and beyond. After an introductory section, we work from broader biogeographical questions to matters that have more local, sp

Shallow marine mixed siliciclastic–carbonate shoals, a carbonate platform, and the subsequent development of a reefal buildup occur in sequence from the late Chattian to the Aquitanian in the Niah area of Sarawak. They document the transition from larger foraminifera-dominated, calcitic environments to scleractinian coral–dominated, aragonitic environments in SE Asia, which correspond to a significant increase in biodiversity. A late Chattian to early Aquitanian phase of carbonate sedimentation was initiated by larger foraminifera on shallow marine argillaceous shoals raising from the seabed a

Preservation of biological diversity is necessary for sustainable development and rational use of coastal resources. In this paper structure of the cliff plant communities of the massif Tuapkhat (the Black Sea coast, Russia) are characterized. Flora of this coastal zone combines features of Mediterranean and middle European Russia types. Herbaceous and shrub life-forms and xeromorphous and petrophilous plant associations dominate at the studied area. The main factor determining the species composition of the examined communities is substrate character.

The genus Helichrysum (Asteraceae) comprises about 600 species of perennial or annual plants distributed in Europe, Asia, and Africa, which are an abundant source of secondary metabolites, such as flavonoids, chalcones, phenolic acids, coumarins, pyrones, and terpenes [1]. In the Republic of Moldova only one species H. arenarium (L.)
