与缺氧共存：金鲈（Macquaria ambigua）在受甲烷渗漏和长期缺氧影响的栖息地的栖息地和地点忠诚度

我们对原生金鲈（Macquaria ambigua）进行了声学遥测研究，以考察其在澳大利亚墨累-达令盆地（MDB）间歇性康达明河（Condamine River）受甲烷渗漏和缺氧影响区域的移动行为。在研究河段无流量和缺氧期间（标签后 3 个月的溶解氧[DO]），我们采集了鱼类，14 个月后检测到 27 条鱼。广义加性混合模型显示，当水流开始流动以及水温超过 19°C 时，鱼类移动的概率显著增加。金鲈的移动模式和对地点的忠诚度与之前在未受甲烷渗漏和严重缺氧影响的间歇性河流中对该物种的研究结果一致，这表明甲烷渗漏和缺氧并未抑制鱼类的移动，也未使受影响的栖息地不适合鱼类栖息。金鲈可以在溶解氧（<1 毫克/升）比以前描述的 MDB 大体型本地鱼类低得多的水中生存并保持活跃。我们的研究结果表明，基于实地数据的鱼类对长期缺氧和甲烷暴露的行为和生理反应对于指导适当的管理对策非常重要。

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.
