This item was filled under Climate
The development and survival of an important group of marine invertebrates known as sea hares is under threat from increasing boat noise in the world's oceans, according to a new study. Sea hares usually hatch from their eggs to swim away and later feed on toxic alga but this study found that when exposed to playback of boat noise, more eggs failed to develop and those that hatched were more likely to die....

Traditional Palauan Agriculture Supports Healthy Coral Reefs

This item was filled under News
The coral reefs of Palau—an island nation in the western Pacific Ocean—are threatened by sedimentation resulting from land clearing in watersheds. A new study funded by NOAA confirms what Palauans have known for millennia: that cultivated wetlands, in particular taro (Colocasia esculenta) fields, can control soil erosion and reduce the impact of runoff on to near-shore coral reefs.

Antarctic ice sheet is result of carbon dioxide decrease, not continental breakup

This item was filled under Climate
Climate modelers have shown that the most likely explanation for the initiation of Antarctic glaciation during a major climate shift 34 million years ago was decreased carbon dioxide levels. The finding counters a 40-year-old theory suggesting massive rearrangements of Earth's continents caused global cooling and the abrupt formation of the Antarctic ice sheet. It will provide scientists insight into the climate change implications of current rising global carbon dioxide levels....
