Introduction to Mark-Recapture Studies and Closed Population Models

Explore mark-recapture studies and closed population models in this 37-minute lecture. Delve into the Lincoln-Petersen model, its limitations, and the Chapman modification. Learn about the Schnabel estimator, methods for addressing resampling, and estimating population sizes. Gain insights into open population models and tagging techniques for individual identification. Discover how researchers name and categorize fish populations, and understand the importance of specificity in naming conventions. Examine the complexities of additions and losses in population studies, and explore the broader implications of these methodologies in understanding the natural world.
