摘要

中欧的片脚类动物群在上个世纪发生了巨大的变化。在过去的30年里，这种变化急剧增加。这种动态在德国东北部得到了充分的证明。本研究将其置于景观生态背景下。一个迁移的例子是Gammarus glustris G.O. sar, 1864年，一个有多种栖息地的极地物种，但被降级为遗迹栖息地。这个物种原来是一个非常弱的竞争者。随着1835年(可能在20世纪60年代)Gammarus roeselii Gervais的移民，它已经成为德国东北部的遗迹物种。几十年后，大量引进的双角麻鲈属、双角麻鲈属和棘麻鲈属的彭托海种加剧了这一过程。

Drastic changes of the amphipod fauna in northern Germany and the displacement of Gammarus lacustris G.O. Sars, 1864 to relict habitats/status

The amphipod fauna of Central Europe has changed dramatically over the last century. This change has increased dramatically over the past 30 years. This dynamic is well documented in northeast Germany. This study places it in a landscape-ecological context. An example of a displacement is Gammarus lacustris G.O. Sars, 1864, a circumpolar species with a variety of habitats, but relegated to relic habitats. The species turns out to be a very weak competitor. Already with the immigration of Gammarus roeselii Gervais, 1835 (probably in the 1960s), it became a relic species in northeast Germany. Massive waves of introduction of Pontocaspian species of the genera Dikerogammarus, Pontogammarus and Echinogammarus a few decades later intensified this process for this and other species.

期刊介绍： Knowledge and Management of Aquatic Ecosystems (KMAE-Bulletin Français de la Pêche et de la Pisciculture since 1928) serves as a foundation for scientific advice across the broad spectrum of management and conservation issues related to freshwater ecosystems. The journal publishes articles, short communications, reviews, comments and replies that contribute to a scientific understanding of freshwater ecosystems and the impact of human activities upon these systems. Its scope includes economic, social, and public administration studies, in so far as they are directly concerned with the management of freshwater ecosystems (e.g. European Water Framework Directive, USA Clean Water Act, Canadian Water Quality Guidelines, …) and prove of general interest to freshwater specialists. Papers on insular freshwater ecosystems and on transitional waters are welcome. KMAE is not a preferred journal for taxonomical, physiological, biological, toxicological studies, unless a clear link to ecological aspects can be established. Articles with a very descriptive content can be accepted if they are part of a broader ecological context.
