The discovery of fossil insects, nematodes and fungi preserved in amber from sites in Otago is shedding new light on New Zealand's geological and biological history.
When considering human impacts on earth systems, disturbance to the carbon cycle grabs the headlines. But another critically important earth process, the nitrogen cycle, has also seen major disruption from human activity.
When exposed to nitrogen fertilizer over a period of years, nitrogen-fixing bacteria called rhizobia evolve to become less beneficial to legumes - the plants they normally serve, researchers report in a new study.
