Drought in California and much of the western United States has been severe enough over the last two decades to be considered a mega-drought, possibly the worst in a millenium. Prolonged drought such as this reduces agricultural yields, and increases forest mortality and wildfire risk. Despite

This project aims to test whether and how herbivory by slugs and snails controls yellow starthistle (Centaurea solstitialis)populations. It consists of pairs of self-contained starthistle gardens in 20 locations around JRBP.

The most active taxonomic research at JRBP is that by Paul Arnaud, Jr., emeritus curator of Entomology at the California Academy of Sciences. Frequently he has one or more emergence traps located along the margin of the main lake or the middle lake.

Many North American ants and lycaenid butterflies have a mutualistic relationship in which the ants protect butterfly larvae from parasitoid wasps, and the butterfly larvae secrete honeydew which the ants consume.
