We studied the impact of simulated global change on a high alpine meadow plant community. Specifically, we examined whether short-term (5 years) responses are good predictors for medium-term (7 years) changes in the system by applying a factorial warming and nutrient manipulation to 20 plots in Latnjajaure, subarctic Sweden. Seven years of experimental warming and nutrient enhancement caused dr...

Savannas are characterized by the coexistence of two contrasting plant life-forms: woody and herbaceous vegetation. During last decades, there has been a global trend an increase in cover spread shrubs trees into areas that were previously dominated grasses. This process, termed bush encroachment, is associated with severe losses ecosystem functions typically difficult to reverse. It assumed be...

Combating the legacy of deforestation on tropical biodiversity requires the conversion to forest of large areas of established pasture, where barriers to native plant regeneration include competition with pasture grasses and poor propagule supply (seed availability). In addition, initial woody plants that colonise pasture are often invasive, non-native species whose ecological roles and managem...

In terms of the hydraulic effect plant flexibility, particular note is calculation formula that was proposed by Kouwen, which combines roughness riverbed with community parameter MEJ (including modulus elasticity). Kouwen’s method developed on basis laboratory experiments low vegetation (grasses). According to authors this work, can also be used evaluate resistance medium (shrubs) deforming und...

Abstract. Archaeological research in high mountain regions has gotten a lot more attention since the discovery of copper age mummy called “Ötzi” Ötztaler Alps 1991. In Tyrolean Stubai Alps, Mesolithic site Ullafelsen at 1869 m a.s.l. (above sea level) close to recent upper timberline Fotsch Valley represents, on one hand, very important archaeological reference and offers, other intriguing ques...

Soil properties affect plant growth and cause variation in leaf functional traits. Lycium ruthenicum Murray is one of the desert dominant shrubs halophytes lower reaches Heihe River, Northwest China. We analyzed trade-off relationships 14 traits eight L. populations growing at varying distances from river discussed effects that soil have on The results showed that: Lower nitrogen (N) content in...

introduction: this study was carried out to determine elements (li, na, k, mg, ca, ba, b, al, si, v, cr, mn, fe, co, ni, cu, zn, se, ag and p) in the suaeda vermiculata (s. vermiculata) and suaeda aegyptiaca (s. aegyptiaca) in three different regions of southern iran using inductively coupled plasma optical emission spectrometry (icp-oes) after microwave-assisted acid digestion. materials and m...
