摘要

气候变化正在改变河流的热状态,对水生生物造成影响。大多数记录在案的河流温度的长期变化都来自大河。我们对小源头溪流的水温趋势知之甚少,尤其是那些在北部有小湖泊的地区。我们分析了加拿大安大略省一项长期流域研究中36年的河流温度观测,以了解上游河流是如何对气候变化做出反应的。研究发现,地下水(GWF)和湖源(LF)在春季(0.19-0.60°C / 10年)变暖,而湖源(LF)在秋季(0.39-0.72°C / 10年)变暖。两种河流类型在夏冬两季均表现出较弱的温度变化趋势。这些结果强调,包括源头溪流和小湖泊在内的河流网络视角,以及热状态的季节性变化,对于理解水生生态系统对气候变率的响应是重要的。

Thermal regimes of groundwater- and lake-fed headwater streams differ in their response to climate variability

Stream thermal regimes are being altered by climate change with consequences for aquatic organisms. Most documented long-term changes in stream temperature are from large rivers. We know less about water temperature trends for small headwater streams, especially those found in northern landscapes that contain small lakes. We analyzed 36 yr of stream temperature observations from a long-term watershed study in Ontario, Canada, to understand how headwater streams are responding to climate variability. We found that groundwater-fed (GWF) and lake-fed (LF) streams exhibit contrasting responses, as GWF streams warmed in the spring (0.19–0.60°C per decade) and LF streams warmed in the fall (0.39–0.72°C per decade). Both stream types exhibited weak temperature trends in summer and winter. These results highlight that a stream network perspective that includes headwater streams and small lakes, and accounts for seasonal changes in thermal regimes, is important for understanding aquatic ecosystem response to climate variability.

期刊介绍: Limnology and Oceanography Letters (LO-Letters) serves as a platform for communicating the latest innovative and trend-setting research in the aquatic sciences. Manuscripts submitted to LO-Letters are expected to present high-impact, cutting-edge results, discoveries, or conceptual developments across all areas of limnology and oceanography, including their integration. Selection criteria for manuscripts include their broad relevance to the field, strong empirical and conceptual foundations, succinct and elegant conclusions, and potential to advance knowledge in aquatic sciences.
