Conservation Biology
Exam Answer Key
Course Introduction
Conservation Biology is an interdisciplinary course focused on understanding and preserving biodiversity by integrating principles from ecology, genetics, management, and social sciences. The course explores the causes and consequences of species extinction, habitat loss, and ecosystem degradation, while examining conservation strategies that address these challenges. Students will learn about topics such as population dynamics, conservation genetics, restoration ecology, reserve design, and the role of policy and community engagement in maintaining healthy ecosystems. Through case studies and applied projects, the course emphasizes critical thinking and problem-solving skills essential for modern conservation practice.
