Helv. 118: 59 – 70. Pollen morphology of 20 Turkish Crataegus L. taxa (Rosaceae)
was studied using light and scanning electron microscopy to assess whether
pollen traits are of taxonomic value in this species group. The most frequent
aperture type was tricolporate, but non-tricolporate pollen grains
(trisyncolporate, tet... hiện toàn bộ
Mycorrhizal infection indicates the suitability of different management treatments for nature conservation in calcareous grasslandSpringer Science and Business Media LLC - Tập 119 - Trang 87-94 - 2009

The vegetation composition of calcareous grasslands in Central Europe is mainly
determined by the applied management treatments and the nutrient status of the
ecosystems, but these factors cannot clearly be separated. Recently several
authors reported a shift in growth-limiting plant nutrients from nitrogen to
phosphate. Therefore, we tested the interaction between management and plant

Genetic diversity, phenotypic variation and local adaptation in the alpine landscape: case studies with alpine plant speciesSpringer Science and Business Media LLC - Tập 119 - Trang 125-133 - 2009
Jürg Stöcklin, Patrick Kuss, Andrea R. Pluess
Plant survival in alpine landscapes is constantly challenged by the harsh and
often unpredictable environmental conditions. Steep environmental gradients and
patchy distribution of habitats lead to small size and spatial isolation of
populations and restrict gene flow. Agricultural land use has further increased
the diversity of habitats below and above the treeline. We studied the
consequences of... hiện toàn bộ
Five-year changes in Swiss mire vegetationSpringer Science and Business Media LLC - Tập 120 - Trang 15-27 - 2010
Ulrich Graf, Otto Wildi, Meinrad Küchler, Klaus Ecker
To assess whether short-term changes in mire vegetation can be detected using
the phytosociological approach, paired vegetation relevés from two surveys of
112 mire sites of Switzerland were assigned to phytosociological alliances
through a numerical approach. About 30% of the plots were assigned to different
alliances in the two surveys. These transitions were analysed based on species
