Advanced Distance Sampling: Estimating Abundance of Biological Populations

Detailed Summary of the Book

The book begins with an overview of distance sampling principles, highlighting the framework’s importance and its applications in conservation biology, ecological research, and wildlife management. It then progresses to more advanced topics, covering various survey designs, statistical modeling techniques, and practical challenges that researchers face during field implementation.

The authors dedicate significant attention to the importance of detecting probabilities and how they influence population estimates. The use of line transects and point transects is explored extensively, providing readers with the tools needed to determine which approach best suits their particular study. Furthermore, the text incorporates real-world examples and case studies from diverse ecological systems to offer readers practical insights and demonstrate the application of theory to practice.

Advanced statistical models like Mark-Recapture Distance Sampling (MRDS) and Hierarchical Distance Sampling (HDS) are featured, reflecting current trends in population modeling. The book also emphasizes computational solutions, particularly the use of R and specialized software like Distance, making it highly relevant to the data-intensive workflows of today’s researchers.

Each chapter provides a logical progression, complete with exercises, references for further reading, and critical discussion points that encourage readers to engage with the material deeply. This combination of practical application and theoretical rigor sets this book apart as a crucial resource in quantitative ecology.
