Some UF Biology students who journeyed from Florida to study the biodiversity of the desert southwest- here completing an incredible hike of Arch Canyon, Organ Pipe Cactus National Monument. This class doesn’t happen w/o our public lands!

The US *already* has tariffs, import quotas, and subsidies that basically mean Americans have been paying ~ double the world price of sugar. Main beneficiaries are 3 sugar outfits in near the Everglades. Lots of ecological fallout, and also why we use so much corn syrup in this country.

Plant disease, hort folks: any recommendations for my kumquat and mandarin trees? (N. Fl). On the kumquat only older leaves are yellowing but on the mandarin, they seem to yellow shortly after reaching full size. Is this greening or just a nutrient issue?
