Some varieties of ensatinas along the California coast developed convincing camouflage to seamlessly blend in with their surroundings, while others in the Sierra Nevada mountain range adopted disruptive patterning — displaying high-contrast splotches of color to break up the outlines of their bodies against the forest floor. Spranger is collecting individuals like this one and housing them temporarily (before rereleasing them) at UC Santa Cruz's Coastal Science Campus. During COVID-19 times, the "army of undergraduates" that usually help out are not on campus, so she has been the only one caring for the animals, heading to the lab daily, dutifully tracking their complicated feeding and watering charts pasted to the doors of the climate-controlled rooms. Spranger, and her adviser, ecologist Barry Sinervo at UC Santa Cruz, are st...
