Course Introduction
Conservation Biology Exam Practice
Tests
Conservation Biology explores the scientific principles and practices aimed at preserving biodiversity, ecosystems, and natural resources in the face of human-induced change. The course covers topics such as the causes and consequences of species extinction, genetic diversity, population dynamics, habitat conservation, ecological restoration, and the socio-economic and ethical dimensions of conservation. Students examine case studies, learn methodologies for assessing population viability and habitat health, and develop practical strategies for protecting threatened species and ecosystems, while considering global environmental challenges and policies.
