Precipitation varied across the Southwest in March, but temperatures remained warm throughout the region. Drought-designated areas were expanded in the April 17 U.S. Drought Monitor, with Arizona and New Mexico documenting increases in the extent and intensity of drought. The three-month outlook for April through June calls for equal chances of above- or below-average precipitation in Arizona and New Mexico and increased chances of above-average temperatures for the entire southwestern United States.
The bat, one of three nectar-feeding bats in the U.S., has been delisted as an endangered species and is flourishing. Efforts such as Flowers for Bats will ensure that it continues to thrive.
More than 150 scientists, students and volunteers participated in a BioBlitz that explored the diversity of the area surrounding the U.S.-Mexico Border.
An experiment in combining agriculture with energy efficiency, agrivoltaics involves growing plants beneath photovoltaic solar panels. The project is led by Greg Barron-Gafford in the UA School of Geography and Development.
In this episode of the CLIMAS Southwest Climate Podcast, Mike Crimmins and Zack Guido sit down to discuss what happened with the weather over the last 30 days. They break down the event from mid-February that brought a pulse of moisture to SE Arizona and SW New Mexico, including the connection between atmospheric rivers and precipitation in the Southwest (vs. CA). They also discuss the larger regional patterns of rain, snow, and streamflow within the context of the fading La Niña signal, and wrap things up with a new bet. When will the first 100 degree day occur? - tune in for the details, but as is their pattern, Zack is a bit ambitious in his guess, and Mike tends towards climatology.
Many agricultural crops such as blueberries, chili peppers and tomatoes rely on bees that have adapted a vibration technique to access hidden pollen. Stephen L. Buchmann, a research associate in the Department of Ecology and Evolutionary Biology, discusses his work to study sonicating bees and their evolutionary influence on flowering plants.
