Biosphere and Atmosphere Interactions in Sierra Nevada Forests
نویسنده
چکیده
In the Sierra Nevada, studies are being conducted to assess the impacts of both anthropogenic and biogenic hydrocarbon emissions on regional tropospheric ozone and fine aerosol production. Impacts of ozone deposition and management practices on ecosystem health are also being studied. Human-induced changes in regional air quality have consequences for Sierra Nevada ecosystems and human health. To explore these consequences, research has been conducted at a site in the central Sierra Nevada since June 1997. The research site is located in a ponderosa pine plantation which is downwind of the significant anthropogenic pollution sources of Sacramento and the agricultural Central Valley (Goldstein and others 2000). To illustrate the complex links between air pollution, biogenic gas emissions, and forest management, three specific results from this research are briefly summarized below.

Tropical rain forests play a dominant role in global biosphere-atmosphere C O 2 exchange. A lthough climate and nutrient availability regulate net primary production (NPP) and decomposition in aU terrestrial ecosystems, the nature and extent o f such controls in tropical forests remain poorly resolved. We conducted a meta-analysis o f carbon-nutrient-chmate relationships in 113 sites across the...

Distribution Geographic Range Following Verner et al.’s (1992) technical assessment of the California spotted owl (CASPO), we divided the range of the California spotted owl (Strix occidentalis occidentalis) into two major physiographic provinces: the Sierra Nevada and the mountains of southern California (Tehachapi Pass was the demarcation between the regions). Verner et al. (1992) noted that ...

Effects of fire suppression policies on semi-arid yellow pine and mixed conifer (YPMC) forests in the western US have been well documented, and restoration of forest structure and natural fire regimes are high management priorities to ensure the health and resilience of such forests. However, determining reference conditions for ecological restoration is difficult due to the near absence of und...
