Modeling the Hydrology of Climate Change in California’s Sierra Nevada for Sub-Watershed Scale Adaptation

The rainfall-runoff model presented in this study represents the hydrology of 15 major watersheds of the Sierra Nevada in California as the backbone of a planning tool for water resources analysis including climate change studies. Our model implementation documents potential changes in...

Why Climate Change Makes Riparian Restoration More Important than Ever: Recommendations for Practice and Research

Over the next century, climate change will dramatically alter natural resource management. Specifically, historical reference conditions may no longer serve as benchmarks for restoration, which may foster a “why bother?” attitude toward ecological restoration. We review the potential role for...

Threats and biodiversity in the mediterranean biome

Aim  Global conservation assessments recognize the mediterranean biome as a priority for the conservation of the world's biodiversity. To better direct future conservation efforts in the biome, an improved understanding of the location, magnitude and trend of key threats and...

Favorable environments and the persistence of naturally rare species

In an era of rapid climate change, it is important to understand how naturally rare species—such as those with small geographic ranges, specialized habitat requirements, and low local abundances—have persisted in time and space. In the flora we studied, species with all three forms of rarity...

The fire frequency-severity relationship and the legacy of fire suppression in California forests

Fire is one of the most important natural disturbance processes in the western United States and ecosystems differ markedly with respect to their ecological and evolutionary relationships with fire. Reference fire regimes in forested ecosystems can be categorized along a gradient ranging from “...

Earthwatch: Sierra to Sea

The program aims to increase the understanding of the impacts of climate change; participants will measure meadow stability, greenhouse gas emission and absorption, and biodiversity value. By working together with local scientists, nonprofits and communities, we will provide local land managers with insights into management and restoration efforts to help protect California’s valuable water for both humans and wildlife.

Combined Effects of Reservoir Operations and Climate Warming on the Flow Regime of Hydropower Bypass Reaches of California's Sierra Nevada

Alterations to flow regimes from regulation and climatic change both affect the biophysical functioning of rivers over long time periods and large spatial areas. Historically, however, the effects of these flow alteration drivers have been studied separately. In this study, results from...
