As the summer sea ice melts in the Arctic, polar bears struggling to hunt seals are increasingly turning to sea-birds for food. New scientific research suggests that this change in the polar bear diet could severely reduce sea ducks populations and deprive Arctic peoples of a major source of food and livelihood.
The stories about the poaching of African elephants are deeply imbedded in the carbon isotope tracers that make up the prized tusks. A group of scientists used these tracers to uncover the realities of poaching activities threatening Africa’s elephants today.
Drought has become increasingly prevalent in many parts of the world, but how it will affect ecosystems is often poorly understood. In the Yellow River Delta scientists discovered that another factor, natural enemies, hinder the ability of plants to recover from drought.
Human land-use is a primary cause of biodiversity loss. A recent study shows that human changes to ecosystems has pushed global biodiversity loss beyond safe limits, which could reduce nature’s resilience.
Powerful measurement tools exist to help policy-makers calculate and prioritize their recommendations. Yet there is little information about how environmental valuation actually impacts environmental regulation. So, how do pricing and other forms of measuring natural resources impact policy-making?
We have entered an era where humans have had a profound impact on the planet. In this new world that we have created, what species will endure and what others shall perish? How can we predict what species they will be?
While much research has pointed to a steady decline of the Sumatran orangutan as a consequence of habitat loss, a recent study shows population estimates are higher than previously thought. Are these higher estimates enough to preserve the species?
A team of scientists from the U.S. and Canada has expanded the conversation about climate change and its effects on the world's ecosystems. In a study they look at a critical consequence of climate change — the potential for entire ecological systems to transition into new systems — and begin a discussion of management strategies, including whether or not we should intervene.
