LESSON 3 – REPRODUCTION AND LIFE CYCLE

Understanding Black Bear Reproduction: Survival Strategies and Cub Development

🎯 Lesson Objective:

This lesson aims to provide an in-depth understanding of the reproductive cycle of the Black Bear (Ursus americanus) and its development. You will discover the unique biological adaptations of this species, such as delayed implantation, and learn to recognize the key phases of its life cycle, from sexual maturity to the independence of the cubs. Supported by scientific data and field observations, this module will help you better understand the conservation and management issues of this species.

🧭 Who is this lesson for?

This lesson is aimed at wildlife enthusiasts, biology students, responsible hunters, naturalists and wildlife conservation professionals. Whether you are a novice or looking to deepen your knowledge of the black bear, this course will provide you with concrete and fascinating information.

📚 Lesson content:

🔹 Sexual maturity and growth

Understand the age at which bears reach maturity, the differences between males and females, and the influence of the environment on development.

🔹 Mating behavior

Explore the rutting season, male competition strategies, mate selection and behavioral signals.

🔹 Delayed implantation

Discover this unique mechanism in the female, which allows the implantation of the embryo to be delayed until hibernation begins.
