摘要:
构建实验微藻群落,通过单培养的方式获取各微藻的生长特征参数,以反映其内禀特征和预测其竞争地位.混合培养所有微藻,对微藻竞争结果的理论预测进行实验验证,并开展一系列入侵模拟实验.实验结果表明:纤细角星鼓藻(Staurastrum gracile)在竞争过程中始终保持优势地位,并且能够成功入侵单建种群落,但当被引入由多个微藻组成的共建种群落时其竞争优势不再明显.
Abstract:
Laboratory-based algal microcosms were established, and the growth parameters of algal species in monoculture were obtained in order to reflect their inherent traits and predict their competitive ability. All algal species were also cultured in mixture to empirically test theoretical predictions regarding their competitive ability, and a series of algal invasion experiments were carried out. The experimental results showed that Staurastrum gracile could use limited resources in a more efficient way than other algal species. It was the best competitor, and could successfully invade the established resident community with a low level of diversity. However, it lost its competitive advantage when introduced into the established resident community with a high level of diversity despite its superior competitive ability.
