2,251,951 | Biological diversity and biological integrity: current concerns for lakes and streams | Hughes, RM; Noss, RR | 1,992 | In discussing various concepts of biological diversity and biological integrity, we trace development of the terms from a focus on species to a consideration of ecosystems. We urge the public to extend its concern with species extinction and tropical rain forests to include temperate aquatic assemblages. Examples of lo... | 0 |
42,902 | Tropospheric OH: local measurements and their interpretations | Comes, FJ; Armerding, W; Grigonis, R; Herbert, A; Spiekermann, M; Walter, J | 1,992 | Recently two campaigns have been conducted on the "Schauinsland" (Black Forest, Germany). The concentration of tropospheric OH and its diurnal variation was measured for a number of consecutive days. Together with it the concentrations of O3, H2O, NO(x), and the intensity of the UV were monitored to obtain the necessar... | 0 |
44,161 | Ozone production potential following convective redistribution of biomass burning emissions | Pickering, KE; Thompson, AM; Scala, JR; Tao, WK; Simpson, J | 1,992 | The effects of deep convection on the potential for forming ozone ("ozone production potential") in the free troposphere have been simulated for regions where the trace gas composition is influenced by biomass burning. Cloud dynamical and photochemical simulations based on observations in 1980 and 1985 Brazilian campai... | 0 |
43,254 | The response of spring wheat (Triticum aestivum L) to ozone at higher elevations: II changes in yield, yield components and grain quality in response to ozone flux | Fuhrer, J; Grimm, AG; Tschannen, W; Shariat-Madari, H | 1,992 | The effect of ozone on the yield, yield components and grain composition of spring wheat (Triticum aestivum L., cv. Albis) was investigated in 1989 and 1990 at 900 m above sea level. Plants were grown from the three-leaf stage until harvest in open-top chambers ventilated with charcoal-filtered air (CF), unfiltered air... | 0 |
34,579 | A generalized, lumped-parameter model of photosynthesis, evapotranspiration and net primary production in temperate and boreal forest ecosystems | Aber, JD; Federer, CA | 1,992 | PnET is a simple, lumped-parameter, monthly- time-step model of carbon and water balances of forests built on two principal relationships: 1) maximum photosynthetic rate is a function of foliar nitrogen concentration, and 2) stomatal conductance is a function of realized photosynthetic rate. Monthly leaf area display a... | 0 |

48,218 | Relaxed Arakawa-Schubert: a parameterization of moist convection for general circulation models | Moorthi, S; Suarez, MJ | 1,992 | ABSTRACT A simple implementation of the Arakawa and Schubert (1974) cumulus parameterization is presented. The major simplification made is to "relax" the state toward equilibrium each time the parameterization is invoked, rather than requiring that the final state be balanced, as in the original Arakawa-Schubert im... | 0 |
52,840 | The antiozonant ethylenediurea does not act via superoxide dismutase induction in bean | Pitcher, LH; Brennan, E; Zilinskas, BA | 1,992 | ABSTRACT It has been proposed that the mode of action of ethylenediurea, a very effective antiozonant, is via an increase in the antioxidant enzyme superoxide dismutase (EH Lee, JH Bennett [1982] Plant Physiol 69: 1444-1449). Data presented here refute that hypothesis. No ethylenediurea-associated increases in Cu/Zn-... | 0 |
43,406 | Photochemical pollution at two southern California smog receptor sites | Grosjean, D; Williams EL, II | 1,992 | BIOSIS COPYRIGHT: BIOL ABS. A one-year survey of air quality has been carried out at two southern California (USA) inland locations, Perri sand Palm Springs (90 km E-SE and 120 km E of Los Angeles) to evaluate transport of photochemical smog from the Los Angeles area and to assess population exposure to toxic air pol... | 0 |

43,819 | The effects of ambient air on a semi-natural grassland community | Evans, PA; Ashmore, MR | 1,992 | The effect of filtering ambient air pollution on biomass production and population dynamics of a semi-natural grassland in rural southern Britain was studied over two successive seasons using open-top chambers. No effects were observed in 1988 when ozone concentrations were relatively low, but in 1989 when ozone level... | 0 |
43,012 | A gas exchange system to study the effects of leaf surface wetness on the deposition of ozone | Fuentes, JD; Gillespie, TJ | 1,992 | A leaf chamber system has been developed for measuring the uptake of ozone (O3) by whole plant leaves artificially wetted with dew or raindrops. Tests showed negligible amounts of O3 being lost on internal walls of the chamber, and good heat and mass transfer characteristics without the use of internal mixing fans. The... | 0 |
43,134 | Three-year growth responses of Pinus taeda L to simulated rain chemistry, soil magnesium status, and ozone | Edwards, NT; Edwards, GL; Kelly, JM; Taylor, GE, Jr | 1,992 | Height, diameter, and biomass were measured for loblolly pine (Pinus taeda L) seedlings grown in soil containing 15 or 35-mu-g Mg g-1 and exposed from May to October in 1987, 1988, and 1989 to three O3 concentrations (sub-ambient, ambient, or twice-ambient) and to rain pH levels of 3.8 or 5.2.

38,777 | Biochemical composition of loblolly pine reflects pollutant exposure | Friend, AL; Tomlinson, PT; Dickson, RE; O'Neill, EG; Edwards, NT; Taylor, GE, Jr | 1,992 | Under experimental conditions, the growth of loblolly pine (Pinus taeda L.) is often responsive to ozone at near-ambient concentrations. However, little is known of the biochemical changes associated with this or other pollutants. Loblolly pine seedlings in open-top chambers were exposed to combinations of ozone (sub-a... | 0 |
