They’re small and almost unnoticeable, until their population explodes. Now recent swings in Norway’s small rodent populations have underscored the importance of these creatures for the health of the entire natural community.

Ecological food to have longer life

Have you heard about the method that keeps salmon fresh for a whole month, without the use of chemicals?

Wolves love and fear forest roads

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.
