Phylogeography of a tough rock survivor in European dry grasslands
Phylogeographic analyses of plants in Europe have revealed common glacial refugia and migration routes for several trees and herbs with arctic-alpine distributions. The postglacial histories of dry grassland species in central Europe have rarely been analyzed, even though the extremely species-rich habitat is threatened. Sedum album (Crassulaceae) is a common inhabitant of rocky sites in centra...
متن کاملPedashenko et al.: Dry grasslands of NW Bulgarian mountains
The syntaxa are arranged according to descending syntaxonomic rank and, within the same rank, alphabetically. In round brackets the correct names for type syntaxa are provided whose names are illegitimate or which are considered as syntaxonomic synonyms. An asterisk (*) after the year of an author citation indicates that the protologue (original description) has been checked by us and the sourc...
متن کاملSeasonal Variability in Spectral Reflectance for Discriminating Grasslands along a Dry-mesic Gradient in Switzerland
Dry grasslands in Switzerland are species-rich habitats resulting from a traditional agricultural land use. Almost 40% of plant and in some cases over 50% of the animal species present on dry grasslands are included in the red lists, and are classified as endangered or threatened. Furthermore, it is estimated that about 90% of dry grassland in Switzerland have been transformed to other land cov...
متن کاملPatterns of Genetic Variation across Altitude in Three Plant Species of Semi-Dry Grasslands
BACKGROUND Environmental gradients caused by altitudinal gradients may affect genetic variation within and among plant populations and inbreeding within populations. Populations in the upper range periphery of a species may be important source populations for range shifts to higher altitude in response to climate change. In this study we investigate patterns of population genetic variation at u...
متن کاملBalancing forest-regeneration probabilities and maintenance costs in dry grasslands of high conservation priority.
Abandonment of agricultural land has resulted in forest regeneration in species-rich dry grasslands across European mountain regions and threatens conservation efforts in this vegetation type. To support national conservation strategies, we used a site-selection algorithm (MARXAN) to find optimum sets of floristic regions (reporting units) that contain grasslands of high conservation priority. ...
