Species diversity of mangrove and continental driftSpringer Science and Business Media LLC - Tập 11 - Trang 213-216 - 1976
Emil Hadač
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 analysisSpringer Science and Business Media LLC - Tập 31 - Trang 315-321 - 1996
Siegfried Bräutigam, Edeltraut Bräutigam
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.

Vegetation Diversity of Screes and Taluses of The Pamir and South-Western Tian Shan in Middle AsiaSpringer Science and Business Media LLC - - 2021
Arkadiusz Nowak, Sebastian Świerszcz, Sylwia Nowak, Marcin Nobis
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... hiện toàn bộ

Vegetation of Tsokar lake and Puga valley, Trans-HimalayaSpringer Science and Business Media LLC - - 1983
M. K. Kaul
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, ... hiện toàn bộ
Release and uptake of minerals during decomposition of plant litter in fishpond littoralSpringer Science and Business Media LLC - Tập 25 - Trang 303-308 - 1990
Blanka Úlehlová
Changes in chemical composition of autochthonous plant litter undergoing
decomposition in litter mesh-bags exposed in a transect across four vegetational
zones of a fishpond littoral were estimated during the spring, summer and winter
season. The highest decomposition rate was found in all four zones in spring,
the lowest one in winter. The decomposition was faster in the two aquatic than
in the t... hiện toàn bộ
