This course focuses on ecology, behavior genetics and biological rhythms, emphasizing the application of this knowledge to address environmental challenges. Students will explore the consequences of pollution and climate change, develop critical thinking skills for environmental protection, and design ecological solutions. Key topics include the impact of xenobiotics on organisms, the genetics of behavior in animals and humans and the mechanisms of stress response. Students will also study seasonal ecological changes and the role of climate change in these processes, as well as circadian rhythms and their molecular basis. Additionally, the course examines biological rhythms and their types, with examples from various organisms. The course aims to provide an in-depth understanding of molecular mechanisms and equip students with the skills needed to solve ecological problems effectively.
