ISSN: 1573-5052Keywords: Dry grassland communities ; Festuco-Brometea ; Spatial pattern ; Stomatal behaviour ; Water relationsSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The spatial pattern of species and microhabitats in a dry grassland mosaic in a Central Alpine valley was studied by a variance/mean analysis. In addition, the water-usage strategies of the dominant species were investigated. A significant correlation between species pattern and microhabitat pattern was found for the grass species. Grasses, with their homorhizal root system, are unable to exploit sources of water in deep rock crevices, and are therefore dependent on the water-storage capacity of the particular soil layer. Dwarf shrubs and succulents (with one exception) are independent of this latter water source. The common chamaephytes exhibit contradictory types of stomatal behaviour.Artemisia alba is characterized by a water-conservation strategy, whereasHelianthemum nummularium spp.obscurum andTeucrium chamaedrys are not. The careful usage of the water reserves byArtemisia alba would seem to represent an adaptation to dry grassland conditions. The other dwarf shrubs, in contrast, with their ‘water-wasting’ strategy, have a root system like that ofArtemisia and are unable to compensate for the higher rate of water loss. Thus, the observed ecophysiological differences cannot be interpreted as being ‘different solutions to the same problem’, as a result of divergent evolution. Two alternative interpretations are: a) the stomatal behaviour of the chamaephytes is a characteristic of their respective genera and which is not particularly adaptive here; b) the dry grasslands studied are the remnants of a former vegetation type, which had a low level of competition.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5052Keywords: Austria ; Disturbance ; High altitudinal grassland ; Trampling impactSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The long term effect of tourist trampling on a high altitudinal grassland (Caricion curvulae) in the Tyrolean Alps was investigated. Even under slight trampling the frequency of sensitive species decreases. The most sensitive species were found to be fruticose lichens, followed by mosses, some forbs and broadleaved grasses. Tolerant to trampling are the dominant species Carex curvula, and Ligusticum mutellina, which do not disappear completely even at a tourist frequency of 150 tourists per metre per day. Trampling increases soil bulk density moderately but has no marked effect on the soil water content. Comparison with high alpine sedge heath vegetation in North America shows a surprising uniformity of this vegetation type in response to trampling and also indicates that the common generalisation that alpine ecosystems are fragile and sensitive to disturbance does not hold true in this context. Furthermore these results represent evidence against the theory that ecosystems with low diversity are much more sensitive to arteficial impact than ecosystems with high diversity. However, if even the most resistant plants which are the dominant sedges are destroyed completely the rate of recovery is very low and may last for a long time. In the case of Carex curvula this is supported by the fact that it has very low seed production and grows mainly vegetatively. The rate of spread of the rhizome system of this species is 8 mm in 10 years. Similar figures may apply for the sedge species dominating in the alpine vegetation of North America. Thus fragility of this vegetation in regard to trampling does not mean low tolerance but low regeneration.Type of Medium: Electronic ResourceURL:
