A forest that is also a disturbing memorial to Mussolini recently burned down.
Bringing back aurochs is a competitive and ambitious venture aiming at recreating wilderness in Europe. But ethical and scientific questions linger.
The use of Agent Orange in Vietnam had deep impacts, including a poisoned water supply, birth defects and cancer. Despite decades of attempted litigation, justice for spraying victims seems unlikely.
Climate change is making berries ripen early in Kodiak, Alaska, luring bears away from eating salmon. This shift may not hurt the bears, but could have far-reaching impacts on surrounding forests.
Drains take up precious but inaccessible open space in our cities. Converting these to living streams running through the suburbs could make for healthier places in multiple ways.
Plants produce toxic fruit for everything from deterring fungi to causing constipation.
Flooding in India's main financial hub is a reminder that urban growth has to work with nature.
Some leaves are millimetres across, and others are a metre square. An international study has found the essential factors controlling leaf variations.
For mapping patterns of plant invasion from the sky, understanding plant behaviour on the ground and using it along with remote sensing cameras, is crucial.
As the Discovery Channel and National Geographic Wild unleash a week of dueling shark programs, a biologist advises viewers to take what they see with a large grain of sea salt.
Pond life can recolonise from seeds and eggs which lie dormant in the soil.
The planet has seen five 'mass extinctions' over the past half billion years, but each was followed by an explosion in biodiversity.
We can't return degraded landscapes to their original state but we can change the way people relate to their local environments.
In an urbanizing world, people increasingly are seeking out nature in cities. Research shows that diverse species of animals, plants and insects can thrive in areas that humans have altered.
Most of the earthworms in the US Northeast and upper Midwest are nonnative species. Scientists are finding increasing evidence that invasive worms and invasive plants may help each other.
Before we decide to eradicate or control an invasive species, like carp, we need plenty of scientific evidence and independent assessments first.
The "decision science" approach helps avoid unanticipated consequences of programs to bring species such as New Zealand's little bush moa, Waitomo frog, or laughing owl back from extinction.
Trump wants to scale back national monuments on federal lands in the name of boosting the economy. But this would undo decades of investments to manage our cultural and ecological resources.
Sea otters had been absent from this Alaskan national park for at least 250 years. By marrying math and statistics, scientists map this animal's successful comeback.
