This paper deals with possible effects of rising CO2 and temperature on alpine vegetation. Present carbon dioxide concentrations still limit photosynthesis in most plant species, and a higher degree of limitation can be anticipated for plants living
under reduced atmospheric pressure at high altitudes. High altitudes plants are therefore particularly suited for early warning components of a comprehensive global monitoring effort on vegetation change. This recommendation is also warranted by the fact
20 drillings and 53 soundings were made on the two watershed mires in norht-eat Poland. Subfossil plant communities were reconstructed on the basis of 120 analysis of the peat botanical composition, lines of plant succession and reaches plant
This issue contains two papers. 1. Differentiation of thermal conditions in coffee fields under the influence of a shading and wind protecting plants. The study is based on phytoclimatic investigations at coffee plantations in Ea-Kmat (Tay Nguyen
Estimation quantitative de l'impact des facteurs météorologiques sur l'intensité de la transpiration des plantes dans les géosystèmes steppiques
A l'aide de l'analyse de régression, établissement d'une relation entre la transpiration de 4 plantes (pâturin, armpise, luzerne, élyme) et différents facteurs météorologiques (température du sol, vitesse du vent, humidité atmosphérique, bilan
This paper describes the regulatory framework, presents a model of the water-using firm, and tests hypotheses regarding the use of municipal treatment works by industrial plants. The findings allow to infer that use of public treatment works
expanded with the apparent subsidy. Taxpayer-funded sewage treatment plants become a subsidy for industrial production.
Changes on vegetation caused by man can be found out by comparing plants reconstructed since 3 000 B.C. with present vegetation on the basis of development of human society. Today, industry in Slovakia is concentrated in 12 areas. There were
separated 4 types of landscape having various intensity of man's interference with plant formation. - (MS)
The AA. focus here on the description and interpretation of the plant micro- and macrofossil assemblages from the lake silt, including documentation of redeposited plant remains and the implications of these assemblages for Wisconsinan events
L'Artemisia kelleri N. Krasch., dans le nord-ouest du Karakum, est considérée comme une plante de ressource, dont la matière première peut être utilisée dans les branches d'industrie alimentaire, de la parfumerie et médicinale au Turkménistan. Les
résultats de l'étude de sa répartition, les particularités de son développement et la productivité de l'armoise sont donnés. Les particularités biologiques de l'armoise lui permettent de jouer le rôle de plante pionnière lors de la colonisation des sables de
Indication par les plantes des interrelations des géosystèmes de milieu humide et dus à la salinisation en Ouzbékistan
des « plavni » (territoires inondables) en bordure des lacs. Les foyers et la direction de ces processus peuvent être déterminés d'après la distribution des plantes indicatrices à la limite des surfaces salées et non salées.
