Gradient of Soil Fertilization Helps Tundra Shrubs Expand Across the Arctic

Scientists at the Arctic LTER find that different points along a gradient of soil fertility aid ectomycorrhizal and ericaceous tundra shrubs. Their findings hint at the potential for those two types of shrubs to co-expand over the Arctic—a previously unconsidered scenario that could have vast implications for the future of the northern tundra

Arctic LTER: Fertilization, fire and plant community change

The Arctic tundra ecosystem has naturally low biodiversity and is experiencing changes due to the influences of climate change. Over the past 30+  years, researchers at the Arctic LTER site have developed a suite of experiments to study the effects of expected climate changes on the ecosystem as well as conducting continued monitoring of ecosystem… Read more »
