摘要

The investigation carried out in one of the mostimportant wetland zone with an international value -Danube Delta Biosphere Reserve aims to assess ecologicalstatus of forest ecosystems under different managementand climatic conditions. Ecophysiological analysis of plantcommunities to evaluate their adaptation status togetherwith qualitative and quantitative aspects of soil mesofaunafor understanding the indirect and direct effects of forestmanagement practices were approached. Four sites locatedin northern part of Danube Delta were studied - two naturalforests, one of them being a strictly protected area ofnational interest corresponding to IUCN category I and theother one a forest with native species as Populus alba andSalix alba. For comparison two forest plantations (Populusx canadensis and respectively S. alba) were also analyzed.Significant differences were found in gas-exchangeparameters (photosynthesis, respiration, stomatalconductance), water use efficiency and relative watercontent in species from plantations versus natural forests,especially in drought period. The results highlighted themajor influence of climatic conditions that occurred duringthe study period on edaphic mesofauna. Under theinfluence of drought and high temperatures were foundsignificant changes in terms of global abundance, weightof systematic / trophic groups and spatial distribution ofmesofauna.

Alba）。在Gas-ExchangeParameters（光合作用，呼吸，气孔发生）中发现了既志性差异，水分用效率和种植园的物种相对天然森林，特别是在干旱期。结果强调了研究期间研究期间的气候条件对拭子中梅花的影响。在干旱和高温下的源于全球丰富，系统/营养群体和繁殖的空间分布方面的重大变化。
