Ecologists test stability of Maine ecosystem over 2 decades

The video explores a long-term ecological study on Swans Island, led by ecologist Peter Petraeus. The team investigates the stability of rocky intertidal ecosystems and the potential for abrupt community switches due to environmental changes. They document the effects of invasive species, like green crabs, on mussel beds and rockweed stands. The study highlights the challenges of predicting future ecosystem states and emphasizes the constant nature of change in the natural world.
