Comparison of the Carbon and Water Fluxes of Some Aggressive Invasive Species in Baltic Grassland and Shrub Habitats

Biological systems are shaped by environmental pressures. These processes implemented through the organisms exploiting their adaptation abilities and, thus, improving spreading. Photosynthesis, transpiration, and water use efficiency major physiological parameters that vary among respond to abiotic conditions. Invasive species exhibited special performance in invaded habitat. Photosynthesis transpiration intensity of Fallopia japonica, Heracleum sosnowskyi, Rumex confertus northern trans-Asian origin were performed temperate extensive seminatural grassland or natural forest ecotones. The observed photosynthetically active radiation (PAR) ranged from 36.0 1083.7 μmol m−2 s−1 throughout growing season depending on meteorological conditions habitat type. F. japonica H. sosnowskyi settled naturally formed shadowy shrub habitats characterized lowest mean PAR rates 58.3 124.7 s−1, respectively. R. located open where was 529.35 s−1. Correlating with available sunlight (r = 0.9), highest average photo assimilation rate for (p 0.000). photosynthesis habitats. Transpiration effectivity at leaf level depended many factors. Positive quantitative responses soil confirmed positive tolerance strategies invasive succeeded new during period sustained across a range environments.
