New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…

But scientists have come to realize that an even more acute danger than climate change is lurking in the world's oceans—one that is likely to be triggered by…
But when climate shifted dramatically there some 8 million years ago, precipitating a major change in vegetation, most species became locally extinct rather…
Now a team led by Dr Robin Allaby from the University of Warwick have developed a new mathematical model that shows how plant agriculture actually began much…
Ammonia emissions from seabirds have been shown to be a significant source of nitrogen in remote coastal ecosystems, contributing to nutrient enrichment…
A falling leaf often catches a poet's eye, but scientists also wonder about the phenomenon that causes leaves to fall, or abscission in plants. Abscission is…
MIT researchers and colleagues are working to find out whether energy from trees can power a network of sensors to prevent spreading forest fires. What they…
The findings, which have been published in the Proceedings of the National Academy of Sciences (PNAS) of 9th September, bear significant implications for the…
Improved agricultural productivity can help developing countries reduce their reliance on international emergency food relief following natural disasters. This…
A new study shows that the dozens of much smaller outflow glaciers dotting Greenland’s coast together account for three times more loss from the island’s ice…
There’s a new player on the organic gardening front. It's called biochar, and it could be good medicine for the planet as well as for crops, because it can…
