Abstract

Microcosm design is an important factor in interpreting results obtained from studies of the environmental effects, mobility and persistence of contaminants. The behavior of pentavalent arsenic and a radioarsenic tracer was studied in three substrate types exposed to differing levels of stable As dosage. Soil cores excised intact from a natural grassland ecosystem were considered to most reliably represent the natural system under study since they retained the soil structure, and closely simulated the abiotic and biotic complexity, of the grassland ecosystem. The behavior of /sup 74/As in the components of intact soil core microcosms differed appreciably from that observed for the other microcosm types where soil underwent manipulation. These differences were explained primarily on the basis of differences in soil structure.

Photosynthesis/respiration ratios in aquatic microcosms under arsenic stress

Conference Giddings, Jeffrey; Eddlemon, Gerald

The ratio of net photosynthesis (P) to total ecosystem respiration (R) usually declines when an aquatic ecosystem is subjected to various types of stress. P/R ratios were measured in 12 80-liter microcosms containing water, sediment, and entire biotic communities (dominated by Elodea sp.) from a shallow pond. P and R were estimated from changes in dissolved oxygen concentrations during the day and night, respectively. After 10 weeks, the microcosms were stressed by the addition of sodium arsenate at concentrations of 0, 0.066, 11.5, and 143 ppM (as arsenic). P/R ranged from 1.0 to 1.4 in all microcosms before arsenate wasmore »« less

The ratio of net photosynthesis (P) to total ecosystem respiration (R) usually declines when an aquatic ecosystem is subjected to various types of stress. P/R ratios were measured in 12 80-1 microcosms containing water, sediment, and entire biotic communities (dominated by Elodea sp.) from a shallow pond. P and R were estimated from changes in dissolved O/sub 2/ concentrations during the day and night, respectively. After 10 weeks, the microcosms were stressed by the addition of sodium arsenate at concentrations of 0, 0.066, 11.5, and 143 ppM (as As).

Comparative community responses to elevated atmospheric CO{sub 2} in microcosms and intact grassland

Journal Article Chiariello, N - Bulletin of the Ecological Society of America

Ecosystem responses to elevated CO{sub 2} involve components that are difficult to resolve in spatially varying, intact systems. Depending on their functional similarity to the field, experimental microcosms may provide more uniform, accessible analogues. At Stanford University`s Jasper Ridge Biological Preserve, research on grassland responses to elevated CO{sub 2} combines field studies and microcosm experiments on annual communities established from seed. Parallel measurements from year 3 of CO{sub 2} treatments in the field and year 2 in the microcosms (after self-seeding) provide a test of their functional similarity. In both, nutrient-poor serpentine soils supported high plant density (>10,000 m{sup -2}),more »« less
Seasonal variation in carbon dioxide exchange over a Mediterranean annual grassland in California

Journal Article Xu, L; Baldocchi, D - Agricultural and Forest Meteorology

Understanding how environmental variables affect the processes that regulate the carbon flux over grassland is critical for large-scale modeling research, since grasslands comprise almost one-third of the earth's natural vegetation. To address this issue, fluxes of CO{sub 2} (F{sub c}, flux toward the surface is negative) were measured over a Mediterranean, annual grassland in California, USA for 2 years with the eddy covariance method. To interpret the biotic and abiotic factors that modulate F{sub c} over the course of a year we decomposed net ecosystem CO{sub 2} exchange into its constituent components, ecosystem respiration (R{sub eco}) and gross primary productionmore »« less

Field calibration of soil-core microcosms for evaluating fate and effects of genetically engineered microorganisms in terrestrial ecosystems

Technical Report Bolton, H; Fredrickson, J; Bentjen, S; ...

Pacific Northwest Laboratory compared intact soil-core microcosms and the field for ecosystem structural and functional properties after the introduction of a model genetically engineered microorganism (GEM). This project used two distinct microbial types as model GEMs, Gram-negative Pseudomonas sp. RC1, which was an aggressive root colonizer, and Gram-positive Streptomyces lividans TK24. The model GEMs were added to surface soil in separate studies, with RC1 studied throughout the growth of winter wheat (Triticum aestivum), while TK24 was studied throughout a ten month period. Also, RC1 was used in studies conducted during two consecutive field seasons (1988 to 1990) to determine howmore »« less
