Distribution and ecology of the taxa of Rubus L. subgenus Rubus

The brambles of the genus Rubus L. subgenus Rubus are characterized by their so called apomictic reproduction, where the embryo in the seed comes directly from the mother plant without recombination. By chance fertilization with pollen or mutations lead to a great variety of phenotypes that can spread as clones through apomictic reproduction. Many of.. Lire la suite

Effet de la fragmentation des habitats sur des espèces végétales du genre Saxifraga et du genre Lychnis

Nous étudions deux couples d’espèces végétales des genres Saxifraga et Lychnis, dont l’une habite les prairies mésophiles et l’autre les pentes rocheuses siliceuses, deux habitats protégés au niveau européen. Les pentes rocheuses sont fragmentées de par leur nature alors que les prairies mésophiles, jadis répandues, ont diminués à cause de l’intensification de l’agriculture.

Population biology of endangered plant species in newly available habitats

Habitat fragmentation and habitat deterioration are considered to be the major reasons for the decline in the number of populations of many plant species, which are now often threatened with local extinction. Today, nutrient-poor calcareous grasslands are among the most threatened habitat types and often exist only as remnant islands in a matrix of unsuitable environment.

Mountain areas and their importance for the conservation of plant diversity in Central European grasslands

Many formerly common plant species of nutrient-poor grasslands have strongly declined in Europe in the last decades due to changes in land use practices and the use of mineral fertilizers, resulting in the destruction and fragmentation of these grasslands. In mountain areas the intensification of land use practices has only recently begun and many grasslands are still nutrient-poor and traditionally managed.
