Cases of tick-borne disease are on the rise in the US as ticks are expanding their distributions, and new tick species are introduced.

California’s mining and industrial history have led to an excessive build-up of mercury in the Bay Area. As one of the top ten pollutants of the world, this toxic heavy metal has troubling implications for human and environmental health.
Past
Escherichia coli is a common resident of most vertebrate guts, including humans. It assists with vitamin production and prevents colonization of harmful bacteria. But E. coli can also make us sick.
Past
Anthropogenic activities changed our planet over the course of the Holocene, but the scale of human impacts increased dramatically around the mid-20th century, representing the start of the Anthropocene.

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.
Past
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.
Past
Several nitrogen-containing compounds are released to the atmosphere by human activities such as driving automobiles and generating electric power. Ultimately these compounds are deposited on land or water, either in a dry form or carried by rain or fog.
Past
A major gap in our understanding of how Earth's biosphere will respond to rising concentrations of atmospheric CO2 is whether ecosystems will increase their net uptake of CO2 through photosynthesis and growth, and if so, by how much.
Past
The consequences of mammal activity are nearly ubiquitous at JRBP; they include distinctive browse lines on vegetation, animal trails and tracks, scat, dens, and carcasses.
Past
Construction of Searsville Dam in the 1890s created a biotically important lake in a watershed with a high sediment load. Siltation has now reduced the capacity of the lake by about 90 percent.
