Final answer:
Diversity is indeed preserved by creating ecological corridors linking reserves, which aid movement and genetic exchange among species, exemplified by projects like the "Yellowstone to Yukon" initiative.
Step-by-step explanation:
It is true that diversity can be preserved by linking reserves together with corridors. These corridors and connections act as important pathways for species, allowing them to move between different reserves to access resources, mate, and maintain genetic diversity. Large-scale conservation efforts, such as the "Yellowstone to Yukon" and the Mesoamerican Biological Corridor, are examples of initiatives designed to create interconnected preserves. Measures for increasing landscape connectivity include the establishment of continuous corridors, stepping stones, and managing land-use to allow movements of organisms. However, while corridors can increase biodiversity, they may also present risks such as spreading diseases or invasive species. Therefore, conservation strategies must balance the creation of these links with the broader landscape context to maximize benefits to biodiversity.
