The paper presents the results of a study on tree regeneration of forest stands in the Černý důl Nature Reserve, which is situated in the Orlické hory Mountains Protected Landscape area in the Czech Republic. Research was conducted in a spruce-beech stand with an admixture of silver fir, sycamore maple and rowan on two comparative permanent research plots (PRPs) (PRP 1—fenced enclosure and PRP ...

Stampfli A. 1992. Effects of mowing and removing litter on reproductive shoot modules of some plant species in abandoned meadows on Monte San Giorgio. Bot. Helv. 102: 85-92. Reproductive shoot modules have been counted in a permanent plot experiment on Monte San Giorgio (Southern Switzerland) since 1988. The 8 species presented here, including the dominant grass (Molinia arundinacea) and seven ...

We propose a Wigner quasiprobability distribution function for Hamiltonian systems in spaces of constant curvature —in this paper on hyperboloids—, which returns the correct marginals and has the covariance of the Shapiro functions under SO(D, 1) transformations. To the free systems obeying the Laplace-Beltrami equation on the hyperboloid, we add a conic-oscillator potential in the hyperbolic c...

Questions: What are the effects of soil, topography, treefall gaps, tree species composition, and tree density on liana species composition and total liana abundance? Location: A 6-ha permanent plot in a subtropical montane forest in northwest Argentina. Methods:Multiple regressions were used to quantify associations of liana species composition and total liana abundance with edaphic, disturban...

Tropical rainforests are crucial in maintaining about 70% of the world’s plant and animal biodiversity also highest terrestrial carbon reservoir. This study aimed to determine tree species composition, structure stocks Deng National Park which is a semi-deciduous tropical forest (plots 1 2 transition zone savannah (plot 3). Plots demarcation enumeration followed standard protocols for permanent...
