For the ecological restoration of desert lands, the dominant species of fodder plants of the natural flora of the violent and patient ecology were used: Krascheninnikovia ceratoides (L.) Gueldenst., Bassia prostrata (L.) A.J. Scott, Camphorosma lessingii Litv., Artemisia lerhiana L., A. pauciflora Web., Poa bulbosa L. in various quantitative ratios in mixtures. Polydominant pasture ecosystems occupy different tiers of height in the aboveground sphere: semi-shrubs – up to 120-140 cm, dwarf semi-shrubs – up to 45-75 cm, ephemeroid grasses – up to 15-25 cm. This ensures efficient placement of the leaf apparatus for efficient photosynthesis. In the underground sphere, various life forms of fodder plants form root systems and develop various ecological niches for more efficient use of water and mineral resources of a large volume of soil. Polydominant pasture ecosystems, which include various plant life forms, provide higher feed production, which exceeds the production of natural pastures by 3-5 times.

Interactions of water and nutrient flows on C relations are explained and typical features of root:shoot ratios in perennial plants including grasses and woody spp. are discussed. In a hydrostable annual crop plant (cowpea) partitioning was controlled by transpiration rate/leaf area and by the capacity of the root for water uptake. For perennial woody spp. the significance of plant architecture and morphology is demonstrated for a situation of competitive growth. (Abstract retrieved from CAB Abstracts by CABI’s permission)

Abstract Background Catalonia (in the north east of the Iberian Peninsula) is among the most prospected territories in Europe, from the ethnobotanical point of view. The aim of the present paper is to undertake a global analysis in the area considered, including plants, plant life forms, and ethnobotanical data within a physiographic and geographic framework. Methods Data from 21 ethnobotanical prospection areas in Catalonia were collected, analyzed, and compared, with the focus on plant life forms and geographic divisions. Results A total of 824 taxa constitute the Catalan ethnoflora, and 316 of them are shared by the six physiographic zones recognized in Catalonia. When three major geographic areas are considered (Pyrenean, inland, and littoral), 394 taxa have been reported in only one out of the three areas. Concerning life forms, phanerophytes and chamaephytes together, i.e., those taxa present all through the year, are the most cited (37.12%). Conclusions This first study constitutes a new approach to ethnobotanical data analysis. The results show the particular importance of plants with a large distribution area and plants with available biomass throughout the year. Apart from this, other kind of plants, e.g., those present in only one territory, are of interest for its originality and sometimes for the local significance.
