The book delves into the ecological consequences of these migrations, such as nutrient distribution and habitat connectivity, and highlights the importance of migration corridors. Chapters examine avian migration routes across North America, emphasizing critical stopover sites, while also exploring the migrations of insects and mammals and their roles in pollination and seed dispersal. The arguments are supported by long-term tracking studies and ecological experiments.
This work connects to conservation biology and climate science, emphasizing the need to protect these species amid habitat loss and climate change.
