Small flowers focus of big climate research at Missouri Botanical Garden (Links to an external site)

The Missouri Botanical Garden is known for its beautiful plants and flowers, but that’s not where you’ll find ecologist Matthew Austin.

Most days, you’ll find the post-doctoral fellow with Washington University’s Living Earth Collaborative combing the stacks, not of a library, but of the garden’s Herbarium, one of the world’s best research resources for all things plants.

No, autumn leaves are not changing color later because of climate change (Links to an external site)

Many people believe that climate change is pushing back the start of fall leaf color to later in the year. The general thinking is that the warmer conditions anticipated under climate change will mean that trees can “hang on” to their green, energy-producing leaves longer. But scientists do not actually see this happening across North American forests, according to LEC Biodiversity Fellow, Susanne S. Renner, an expert at Washington University in St. Louis.

How birds are adapting to climate crisis (Links to an external site)

Many North American migratory birds are shrinking in size as temperatures have warmed over the past 40 years. But those with very big brains, relative to their body size, did not shrink as much as smaller-brained birds, according to new research from Washington University in St. Louis. The study is the first to identify a direct link between cognition and animal response to human-made climate change.

With funding support from LEC, researchers look at whether Ozark oases at Tyson Research Center — climate change refugia — could help species persist in spite of rising temperatures.

Andean forests have high potential to store carbon under climate change. The study — which draws upon two decades of data from 119 forest-monitoring plots in Colombia, Ecuador, Peru, Bolivia and Argentina — was produced by an international team of scientists including researchers supported by the Living Earth Collaborative at Washington University in St. Louis. The lead author was Alvaro Duque from the Universidad Nacional de Colombia Sede Medellín.

“Climate change is altering when plants are blooming, and it’s disrupting the historic relationships between plants and their pollinators,” said Matthew Austin, an ecologist and biodiversity postdoctoral fellow with the Living Earth Collaborative at Washington University in St. Louis. “But we know remarkably little about what effect that has on how plants interact with one another and the evolutionary consequences of altered plant-plant interactions.”

Climate change is affecting the spread and severity of infectious diseases around the world. The research, led by Vanessa Ezenwa, a professor of ecology at the University of Georgia, and funded by the Living Earth Collaborative at Washington University in St. Louis, describes how parasites can cause animals to produce more methane, a powerful greenhouse gas.

Tropical forests suffered near-record tree losses in 2017 (Links to an external site)

The world’s tropical forests lost roughly 39 million acres of trees last year, an area roughly the size of Bangladesh, according to a report Wednesday by Global Forest Watch that used new satellite data from the University of Maryland. Global Forest Watch is part of the World Resources Institute, an environmental group.
