In this study, the U.S. Geological Survey investigated the use of insects as bioindicators of climate change in sagebrush steppe shrublands and grasslands in the Upper Columbia Basin. The research was conducted in the Stinkingwater and Pueblo mountain ranges in eastern Oregon on lands administered by the Bureau of Land Management. We used a "space-for-time" sampling design that related insect communities to climate and weather along elevation gradients. Overall, our interpretation of these patterns is that insect communities respond positively and negatively to weather and local vegetation more than to long-term climate. Given increasing variability in weather and high probability of extreme weather events, insect communities in sagebrush steppe also may experience considerable fluctuations in composition and abundance, as well as phenology. These findings have implications for many ecosystem services, including pollination, decomposition, and food resources for predatory birds and other vertebrates.

Primates are remarkably adaptable animals that have gone through multiple radiations across a wide range of habitats. Habitats found at high altitudes provide particular challenges for resident primate populations. Landscapes at high altitudes tend to be less productive than neighboring areas at lower elevations, and also present changes in the structure of flora and fauna, species diversity, and density. Although some of the most unique and unexpected solutions to problems of survival are found in high altitude primates, these populations are often understudied. This volume compiles the most up-to-date research on how a variety of primates (prosimians, monkeys, apes, and even humans) respond to conditions at higher altitudes.
