入侵糠虾的营养影响取决于浮游动物群落的组成：中观宇宙实验

入侵物种是淡水生态系统结构和功能的主要威胁，但人们往往对它们在被入侵生境中的功能作用知之甚少，尤其是对杂食性动物。它们对被入侵生态系统的影响可能在很大程度上取决于当地的物种组成，但迄今为止几乎没有证据证明这一点。我们进行了一个中观宇宙实验，以检验源于蓬托-里海的广泛杂食性糠虾（Limnomysis benedeni）自上而下的影响是否与被入侵群落的群落组成有关。我们将不同初始组成的浮游动物群落（以栉水母或桡足类为主）与 L. benedeni 的存在/不存在进行了杂交。我们发现，L. benedeni 的影响取决于群落组成，只有在以 Cladocera 为主的群落中，L. benedeni 才会抑制浮游动物的生物量。这可能与捕食者躲避能力的差异有关，特别是与桡足类相比，优势水蚤类在躲避 L. benedeni 的捕食时效率较低。虽然这些大型浮游食草动物的消失可能会连带影响初级生产者的水平，但我们并没有发现明确的证据，因为在为期两周的实验过程中，浮游植物的生物量大多没有受到影响。基于我们的研究结果，我们呼吁进一步开展原理验证实验，并结合实地观察，以便更好地预测入侵者对不同地方群落的影响。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
