To untangle the relationship between climate change, fall foliage and national park visitors, researchers are asking tourists to check their old photo albums for snapshots that could hold valuable data.
Many deciduous trees put on a dazzling fall foliage display. But coniferous evergreens hold on to their needles and stay green. A biologist breaks down these different survival strategies.
Trees and the shade they provide are one of the best ways of cooling cities. But they also present challenges that are best resolved by managing this shared resource as part of an urban commons.
Cities around Australia have plans to increase their green space, but new research shows not all green spaces are equal. Good tree cover is better than grassed areas for residents’ mental health.
Thirty tree species make up more than half of Australia’s urban forests. Some won’t survive climate change, so cities must plant a more diverse mix of the right species to preserve their tree cover.
Hot weather kills more Americans yearly on average than floods, tornadoes or hurricanes. Three scholars explain how cities can prepare and help residents stay cool.
The species which surround a tree in a forest make up the character of its neighbourhood. Good neighbours can make forests resilient to climate change.
What do earthquakes, wealthy Italian families and your circulatory system have in common? Scientists use fractals, self-similarity and power laws to translate from local to global scales.
