The aim of the natural investigations carried out in two archaeological sites in the SE Poland was to determine their TL age (15 samples) and characterize the vegetation cover with the use of pollen analysis (10 samples) of loess and loess-like deposits sampled in the sites and their close environs. Micromorphological features of loess were examined in one of the sites. The research was carried...

Within the monocotyledons the acquisition of the tree habit is enhanced by either primary growth of the axis or a distinctive mode of secondary growth. However, a few arborescent monocotyledons deviate from this pattern in developing trunks up to four meters high that resemble those of tree ferns, i.e., their "woody-fibrous" stems consist mainly of persistent leaf bases and adventitious roots. ...

Citron watermelon (Citrullus lanatus var. citroides (L.H. Bailey) Mansf. ex Greb.) is an underexploited and under-researched crop species with the potential to contribute diversification in Sub-Saharan Africa. The cultivated drier parts of Southern Africa, mainly by smallholder farmers who maintain a wide range landrace varieties. Understanding molecular morpho-physiological basis for drought a...

Water availability is a critical determinant for the growth and ecological distribution of terrestrial plants. Although some xerophytes are unique regarding their highly developed root architecture and the successful adaptation to arid environments, virtually nothing is known about the molecular mechanisms underlying this adaptation. Here, we report physiological and molecular responses of wild...

The article presents a brief analysis of 20-year changes in climatic parameters the Aktumsuk region Eastern Cliff Ustyurt and their impact on species composition Medicageta sativa formation. From obtained daily indicators 2 sources (NASA POWER meteorological station), long-term trends average, average maximum minimum air temperatures, as well annual precipitation have been established. Data fro...

The paper presents the results of geographical analysis dendroflora Cheboksary. landscaping system Cheboksary is represented mainly by woody vegetation, which grows in public areas, limited-use plantings, as well along streets and main highways Woody vegetation 73 species, which, according to generally accepted systematics plants, belong 43 genera 20 families. based on archaeological data from ...

The alpine grasslands on the Tibetan Plateau are sensitive and vulnerable to climate change. However, it is still unknown how precipitation use efficiency (PUE), the ratio of aboveground net primary productivity (ANPP) to precipitation, is related to community assembly of plant species, functional groups or traits for the Tibetan alpine grasslands along actual environmental gradients. We conduc...

It is difficult to overestimate the importance of cereals in functioning natural ecosystems and their use for human life. They often play role dominants edifiers composition plant cover, primarily herbaceous types vegetation. But they also take part forest phytocenoses different zones. Within Ukraine, Poaceae family includes 71 genera (of which only 4 are culture) 208 species 15 [20]. The cerea...
