摘要

温度是决定跨气候和地理梯度物种分布和丰度的关键因素。在本研究中，我们通过实验测试了溯河大西洋鲑和褐鳟鱼幼鱼之间的竞争是否与温度有关，并评估了温度对这些物种在挪威88条河流中相对丰度的影响。当这两个物种在异地饲养时，它们的体细胞生长率在一定温度范围内（4-16°C）相似。当在同地饲养时，与异地饲养相比，鲑鱼在最冷温度下的生长率大大降低，而鳟鱼则不然。在温度较高时，种间竞争对两种鱼类生长的影响更为相似。实验结果反映在自然种群中鲑鱼和鳟鱼相对丰度的定性模式上，即在夏季温度较低的河流中鳟鱼占优势，而在温度较高的河流中鲑鱼占优势。

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.
