global temperatures rise

Still, the principle has practical applications for scientists trying to measure varieties of plant life in hostile environments — places like conflict zones, tropical and boreal forests, and even the Nike Air Force 1 Womens Arctic.

“Imagine the challenge of trying to sample the tops of the trees,” Gamon said. “People do that: they climb up forests and risk their lives collecting samples from the tops of tropical forests. A drone could fly over that and make it a whole lot safer and easier.”

Monitoring an ecosystem’s biodiversity also allows scientists get an early read on threats from climate change, and leaves room for human intervention to help those Nike Air Zoom Mariah Flyknit Racer Mujer environments adapt. As global temperatures rise, climate stability suffers, increasing the odds of extreme weather events and changing the kind of plants, and animal, that can survive in any given place.

But changes in biodiversity offers more than just an early warning system, said Anna Schweizer, a postdoctoral researcher at the University of Minnesota and lead author of the study that includes the Nike Air Max 90 Damen Grau work of Gamon and half a dozen others. It also enhances an ecosystem’s ability to weather naturally occurring threats like drought and pests.

“Communities made up of individuals that have different traits, together can use the available resource pool more efficiently,” Schweizer said, “which makes a community more productive and resistant to environmental change.”

For example, having a mix of plants that are more or less resilient, Adidas Zx 850 Donna dependent on water or sunlight, warmer or cooler temperatures, means that when one of these variables change, the community as a whole is less vulnerable, and capable of a faster recovery.

For both researchers, the technology is an important step for monitoring biodiversity and adapting to a rapidly changing climate.

“If we lose biodiversity for any reason, and we have changing climates — let’s Nike Roshe Run Femme say increased drought, increased temperatures — an ecosystem may be less resilient,” Gamon added. “That translates into more crop losses, more forest fires, things we’re actually seeing now in Canada.”
