Seasonal changes in trophic interactions: physiological mechanisms and consequences for energy and contaminant flow in a Canadian Shield lake

冬季是水生动物一年中的关键时期。气候变化已经在影响温带地区的冬季气候。考虑到这一点，令人惊讶的是，营养相互作用的季节变化，特别是在冬季，研究得很少。我研究的长期目标是通过研究营养相互作用的季节变化的生理机制和生态系统水平的后果（对能量和污染物流动）来预测气候变化将如何影响水生动物和生态系统。在接下来的5年里，我将在夏季、秋季、冬季和春季在一个研究充分的湖泊（安大略省的Opeongo湖）进行季节性采样，以实现3个目标。

Winter periods are critical times of the year for aquatic animals. Climate change is already dampening winter conditions in temperate latitudes. Given this, it is surprising that seasonal changes in trophic interactions, especially during winter, are poorly studied. The long term goal of my research is to anticipate how climate change will affect aquatic animals and ecosystems by studying the physiological mechanisms and ecosystem-level consequences (for energy and contaminant flow) of seasonal variation in trophic interactions. Over the next 5 years, I will conduct seasonal sampling in a well-studied lake (Lake Opeongo, Ontario) during summer, autumn, winter and spring to address 3 objectives.
