Lakes that 'breathe' ancient carbon: A surprising find in the Congo Basin‎

In the heart of the Congo Basin's Cuvette Centrale, a large depression that hosts the world's largest tropical wetland complex, lie two vast, shallow blackwater lakes, Lake Tumba and Lake Mai Ndombe. Together, they are roughly the size of 420,000 football fields.

Human noise pushes Alaska predators toward night foraging, altering salmon nutrient pathways‎

The age-old question asks, "If a tree falls in a forest and no one is around to hear it, does it make a sound?" While philosophers and scientists alike have pondered this question for centuries, the more relevant question for today's recreation and wildlife managers is: Does it matter what makes the sound?

'Amazing moths': Study pinpoints insect habitat that draws grizzlies to glacier peaks‎

When grizzly bears clamber onto the talus slopes high in Glacier National Park, they're searching for an abundant, fatty meal: army cutworm moths. The inch-long (2.5-centimeter-long) moths hatch on the Great Plains and fly en masse to escape the heat in the stony upper reaches of the Rocky Mountains. Grizzlies hoover them up by the thousands—at about a half-calorie each—as they fatten up for winter.

Honey bees' sense of smell changes from larval to adult life stages, study finds‎

Honey bee larvae lack the sophisticated olfactory capabilities of adult honey bees, a new study finds. Scientists point to this temporary loss of function as a side effect of the nurse bees' heroic level of brood care, calling it a consequence of social evolution. The new findings are detailed in the Proceedings of the National Academy of Sciences.
