Abstract The characteristics of shaded chasmophytic habitats on calcareous rocks in forest conditions are described, where the canopy primarily acts as a shading factor that determines microclimate, humidity and light levels. These communities can be found deciduous forests Carpinion betuli , Fagion sylvaticae Tilio-Acerion alliances, they confined to steep rock faces cliffs. Syntaxonomically, ...

The Metropolis-Hastings (MH) algorithm is a way to sample a provided target distribution π(x). It works by repeatedly sampling a separate proposal distribution T (x, x) to generate a random walk {x(t)}. We consider a modification of the MH algorithm in which T is dynamically updated during the walk. The update at time t uses the {x(t < t)} to estimate the product distribution that has the least...

A library of 600 taxonomically diverse Panamanian plant extracts was screened for DPPH scavenging and UV-B protective activities, and the methanolic extracts of Mosquitoxylum jamaicense, Combretum cacoucia, and Casearia commersionia were submitted to HPLC-based activity profiling. The compounds located in the active time windows were isolated and identified as gallic acid derivatives and flavon...

In this paper, we report a new occurrence of Myricaria germanica (L.) Desf in secondary habitat from the north-eastern part Hungary, edge Bükk Mountains, slag dump Miskolc. The plant is established on steep wall formed during extraction slag. Due to erosion wall, occasionally few plants fall off. age dead specimens between 5 and 13 years, based their growth rings. population about 50 individual...

Ovary-sessile, young fulvous-villous. Calyx shortly constricted above the ovary then funnelshaped, hairy within and without; calyx-tube upwards 5-fluted, the segments triangular, acute, erect.

This study was conducted to investigate the resistance of 4 wild eggplant species (Solanum aethiopium group Aculeatum, S. incanum, macrocarpon, linnaeanum), 3 cultivated varieties (‘Anamur F1’, ‘Pala’, ‘Yamula’), 1 rootstock (KĂśksal F1) and 34 interspecific hybrids Verticillium dahliae Kleb. Fusarium oxysporum f.sp. melongenae. Disease genotypes determined by pathogenicity test. The disease se...
