With an unparalleled network of environmental monitoring stations, research field sites, data, and interdisciplinary scientists, the UA is pioneering use-inspired ecosystem research that helps manage and conserve the lands, forests, oceans, landscapes, and wildlife of the western U.S. and beyond for those who enjoy and depend upon them.
Dr. Philip C. Rosen has studied conservation biology and community ecology of amphibians and reptiles in the American Southwest since 1983, focusing on reptile ecology, aquatic species, deserts, grasslands, and urban environments. He has specialized in ranid frog, kinosternid turtle, and gartersnake conservation and ecology, urban amphibian distribution, ecology and conservation, translocation, and long-term monitoring and research in population and community ecology of desert reptiles.
Modern wildfires are burning longer than they did decades ago, which results in longer fire seasons overall, said Valerie Trouet, an associate professor in the UA Laboratory of Tree-Ring Research.
As the Trump administration wants to slash federal funding for wildfire science, federally funded scientists have been seeking new methods and technologies to predict, prepare and respond. "A wildland fire (budget) cut is a human health cut," said Don Falk, a forest ecologist at the UA.
Around 2,700 scientists from 47 countries have signed a letter supporting a scientific paper by Defenders of Wildlife that concludes President Donald Trump's border wall is a threat to biodiversity. "To say the only way we can deal with human security is a wall — as opposed to electronic surveillance at the line or other means that have proven more effective — is a false pretense," said Gary Nabhan, the W.K. Kellogg Chair in Southwest Borderlands Food and Water Security at the UA.

Experts say a recent European heat wave dried out the continent's foliage, making everything much more likely to catch fire. "The fires in Sweden, I would say, are directly linked to the heat wave going on there and the concurrent drought," said Valerie Trouet, an associate professor in the UA Laboratory of Tree-Ring Research.
Four large wildfires have recently broken out in Central Texas. Climate researchers say the uptick in fires may be related to global warming. "I feel very confident in saying Texas is in the bullseye of climate change," said Donald Falk, a forest ecologist at the UA.
The black squirrel currently accounts for about half of Washington, D.C.'s squirrel population. How that happened is a 116-year-old story. The "black colour morphs" were originally common in colder climates due to climate tolerance. They are rarely seen as far south as Washington, D.C., said John Koprowski, a wildlife conservation professor at the UA.
