General Patterns of Nitrogen Pools and Fluxes in California Annual Grasslands
نویسنده
چکیده
Nutrient availability is a critical controller of plant species composition and productivity and is influenced by the interaction of a number of biotic and abiotic factors (Chapin et al. 2002). In this chapter, we explore the controls over nutrient pools and fluxes across different California grassland types. We will begin with an in-depth discussion of the exoticdominated annual grassland type, where most biogeochemical studies have occurred. Patterns in these annual grasslands will then be compared to those in native grasslands and oakgrassland matrices. Finally, we will review the roles of organisms other than plants in influencing nutrient dynamics.

Soil Carbon Pools in California’s Annual Grassland Ecosystems
Rangeland ecosystems cover approximately one-third of the land area in the United States and half of the land area of California. This large land area, coupled with the propensity of grasses to allocate a considerable proportion of their photosynthate belowground, leads to high soil carbon (C) sequestration potential. Annual grasslands typical of the Mediterranean climates of the western United...
متن کاملO'connor: Nitrogen Balances in Grasslands Nitrogen Balances in Natural Grasslands and Extensively-managed Grassland Systems
An approach is outlined for synthesising current understanding of nitrogen dynamics in natural grasslands and extensively managed grassland systems. The increasing complexity of models is illustrated from recent literature, first conceptualising and eventually process-simulating the dynamics of nitrogen, especially in the soil sub-systems of grasslands. Some comparisons are made between New Zea...
متن کاملPlant water use affects competition for nitrogen: why drought favors invasive species in California.
Abstract: Classic resource competition theory typically treats resource supply rates as independent; however, nutrient supplies can be affected by plants indirectly, with important consequences for model predictions. We demonstrate this general phenomenon by using a model in which competition for nitrogen is mediated by soil moisture, with competitive outcomes including coexistence and multiple...
متن کاملNitrate leaching and nitrous oxide flux in urban forests and grasslands.
Urban landscapes contain a mix of land-use types with different patterns of nitrogen (N) cycling and export. We measured nitrate (NO(3)(-)) leaching and soil:atmosphere nitrous oxide (N(2)O) flux in four urban grassland and eight forested long-term study plots in the Baltimore, Maryland metropolitan area. We evaluated ancillary controls on these fluxes by measuring soil temperature, moisture, a...
متن کاملCalifornia native and exotic perennial grasses differ in their response to soil nitrogen, exotic annual grass density, and order of emergence Citation
49 Early emergence of plant seedlings can offer strong competitive advantages over 50 later-germinating neighbors through the preemption of limiting resources. This 51 phenomenon may have contributed to the persistent dominance of European annual 52 grasses over native perennial grasses in California grasslands, since the former 53 species typically germinate earlier in the growing season than ...
