Sea creatures are threatened by our medicines

Medication ingested by humans is taken up by algae and sea creatures. Entire ecosystems can be affected, according to a Swedish researcher.

Puffin chicks die of hunger

For seven years now, Atlantic puffins have been abandoning chicks and eggs in their nesting colonies because they cannot find enough food. The ocean is teeming with mackerel which consume the small fish that puffins normally feed to their offspring.

Students tote ecosystems in rucksacks

What key discoveries do researchers make about climate change when they use students as sherpas to shuffle ecosystems around on Norway’s west coast fjord landscapes?

Parks stimulate public health

When green areas disappear we lose venues for being physically active. Youth are hit hardest by a loss of parks and undeveloped lots.

Lack of knowledge about insect pollination

Understanding exactly how pollinators – particularly bees - and the plants they pollinate are affected by human activities requires extensive knowledge. This knowledge is also important in calculating the value of pollination ecology.

Soviet Cold War oceanographic surveys opened up to western scientists

A treasure trove of Barents Sea fisheries data stored for decades in Murmansk can help determine the fate of future offshore oil and gas exploitation in the region.

Salmon becomes what it eats

The diet of farmed salmon is no small-fry issue. The quality of the fats and proteins in feeds has quite an impact on the taste of the fish.

Mountain plants crowd at the peaks

A warmer climate is enabling hardy lowland vegetation to ascend mountains and thrive at higher altitudes. When they can’t get any higher, they’ll crowd together on peaks.
