...sland ecosystems, transforming the vegetation from lush
grasslands to scrubby, low-growing tundra. It turns out that the nutrient-poor volcanic soils of the Aleutian archipelago can only support dense grasslands if they receive regular doses of fertilizer in the form of bird droppings. On islands without...

...ine in rainfall will likely push this tall, green, lush
rainforest towards a shorter, more stunted forest. As the forest becomes shorter and its leaf canopy more open, compromising its remarkable resistance to fire, it is clear that drought in tandem with fire can swiftly push the tall, dense rainforests...
