Study Notes
Rabbit Population Adaptation
- Rabbits rely on tall grasses for food and shelter from predators (hawks).
- Climate change resulted in hotter, drier conditions.
- Tall grasses declined, replaced by shorter, drought-tolerant shrubs.
- Rabbits with brownish-gray fur became more common. Their coloration blended better with the sparse, dusty environment, making them less visible to predators.
- Brownish-gray fur camouflages them in the dusty, sparse environment.
- Camouflage reduced visibility to predators, enhancing survival.
- Favourable traits (brown fur) are passed to future generations.
- Changes in vegetation impacted other species, like insects and small herbivores.
- Some populations of other species shrank or migrated.

Description
This quiz explores how climate change has affected rabbit populations, particularly their reliance on tall grasses for food and shelter. It discusses the adaptation of rabbits through changes in fur coloration for better camouflage in a changing environment. Additionally, it examines the impact on other species and ecosystems due to these changes.
