Light-driven tipping points in polar ecosystems - Casey Station, Antarctica
Entry ID: Light_Tipping_Points

Abstract: Some ecosystems can undergo abrupt transformation in response to relatively small environmental change. Identifying imminent "tipping points" is crucial for biodiversity conservation, particularly in the face of climate change. Here we describe a tipping point mechanism likely to induce widespread regime shifts in polar ecosystems. Seasonal snow and ice cover periodically block sunlight reaching ... View entire text
