Species diversity of mangrove and continental drift
Springer Science and Business Media LLC - Tập 11 - Trang 213-216 - 1976
The mangrove formation on the coasts of S. Atlantic is very poor in species (only 6) compared with mangrove in S. and SE. Asia or E. Africa (more than 30). This fact cannot be explained by ecology. It is suggested that the main cause is the historically late origin of the Atlantic due to the continental drift.
Determination of the ploidy level in the genusHieracium subgenusPilosella (Hill) S.F. Gray by flow cytometric DNA analysis
Springer Science and Business Media LLC - Tập 31 - Trang 315-321 - 1996
Ploidy levels of 8 taxa of the genusHieracium subgenusPilosella collected from the same locality were determined by means of flow cytometric estimation of relative nuclear DNA content. The DNA anaysis of isolated nuclei stained with propidium iodide was performed with a flow cytometer equipped with an argon-ion laser. The diploid speciesH. lactucella (2n=18) was used as internal standard. As a rul......
Vegetation Diversity of Screes and Taluses of The Pamir and South-Western Tian Shan in Middle Asia
Springer Science and Business Media LLC - - 2021
This paper presents the results of phytosociological research on scree vegetation of the Pamir and south-western Tian Shan. We collected 222 phytosociological relevés during field studies conducted in 2015–2019, applying the Braun-Blanquet approach. We identified 21 plant communities on mobile and stabilized screes of colluvial cones, aprons and fans, inhabiting mainly the montane and alpine belts......

Insgesamt wurden 4 Assoziationen, 12 Subassoziationen und 28 Varianten festge......
Vegetation of Tsokar lake and Puga valley, Trans-Himalaya
Springer Science and Business Media LLC - - 1983
The alpine zones of Ladakh are floristically and geobotanically very interesting. In the past these were poorly known botanically because of the ruggedness and inaccessibility of the area. The varied climatic conditions and habitat types have a main role to play in establishing the vegetation of these zones. A total of 122 taxa were identified from collections made during the summer months (July, ......
Apomixis, hybridization, and taxonomic complexity in eastern north AmericanAmelanchier (Rosaceae)
Springer Science and Business Media LLC - Tập 31 - Trang 345-354 - 1996
Apomixis and hybridization together contribute to taxonomic complexity inAmelanchier. Hybridization combines genetically divergent genomes and spawns new forms that apomixis perpetuates. Apomixis is aposporous, facultative, and pseudogamous in the genus, and apomicts are generally polyploid, pollen fertile, and pollinated by generalists. That gene flow actually occurs is empirically evident. As ap......
