Class Objectives
/Class Outline The biodiversity we observe today is the product of long-term adaptive evolution of organisms across diverse environments, and is recognized as having manifold values. However, biodiversity is currently under critical threat due to anthropogenic impacts. This course introduces the significance and current status of biodiversity, and explains the processes by which it is generated, the mechanisms by which it is maintained, and the methods by which it is assessed. The course also aims to provide students with an understanding of the concepts of conservation genetics and conservation genomics, which are essential for the appropriate conservation of biodiversity.

Class Schedule lesson1 Ecosystem services provided by biodiversity and their assessment
lesson2 Evolution as a driver of biodiversity
lesson3 Species concepts and speciation
lesson4 Fundamental concepts in phylogenetic analysis
lesson5 Biodiversity in familiar natural environments (1): Anthropogenic impacts and biodiversity
lesson6 Population genetics for conservation (1): Mechanisms of loss and generation of genetic diversity
lesson7 Conservation genomics (1): Methods of genome sequencing
lesson8 Examination and feedback

This course is a continuation of Diversity Ecology II and cannot be taken independently.
