    Notes: Abstract Research on the ecological effects of acidic deposition has yielded information that currently permits a partial assessment of these effects. Establishing a relationship between deposition of acidity and ecological effects is a difficult, lengthy process; the complexity of ecosystems requires an integrated mechanism-level approach in order to obtain quantitative and predictive information. Known ecological effects of acidic deposition appear in surface waters and probably forest eco-systems in eastern North America, northern, and central Europe. Almost all documented anthropogenically acidified surface waters in North America occur in the Adirondack Mountains. The effect of anthropogenic acidification on fish, expressed regionally, seems to be small compared to the total resource at risk. The current rate of acidification of surface water in North America appears to be slow. Acidification of surface water is temporarily reversed with addition of CaCO3. Fish tend to have higher Hg body burdens at lower pH of ambient water. Vertebrates other than fish and amphibians have not been affected by acidification, with the possible exception of local populations of piscivores and insectivores. Some lakes are apparently culturally acidified in southern Scandinavia and southern Scotland, but the limitations of the data restrict assessments. Forest decline is a widespread natural process that may be exacerbated by air pollution. Acidic deposition may contribute to forest decline by interaction with ozone and by the leaching of nutrients from soil. In North America, high elevation red spruce is in an unexplained decline to which both ozone and acidic deposition may be contributing. Acidic deposition may be exerting some unmeasured effect on forest decline in Germany by the further leaching of nutrient deficient soils. Extensive experimental work has failed to disclose unambiguous effects of acidic deposition on crops.

    Notes: Abstract Although there is a great deal of information concerning responses to increases in atmospheric CO2 at the tissue and plant levels, there are substantially fewer studies that have investigated ecosystem-level responses in the context of integrated carbon, water, and nutrient cycles. Because our understanding of ecosystem responses to elevated CO2 is incomplete, modeling is a tool that can be used to investigate the role of plant and soil interactions in the response of terrestrial ecosystems to elevated CO2. In this study, we analyze the responses of net primary production (NPP) to doubled CO2 from 355 to 710 ppmv among three biogeochemistry models in the Vegetation/Ecosystem Modeling and Analysis Project (VEMAP): BIOME-BGC (BioGeochemical Cycles), Century, and the Terrestrial Ecosystem Model (TEM). For the conterminous United States, doubled atmospheric CO2 causes NPP to increase by 5% in Century, 8% in TEM, and 11% in BIOME-BGC. Multiple regression analyses between the NPP response to doubled CO2 and the mean annual temperature and annual precipitation of biomes or grid cells indicate that there are negative relationships between precipitation and the response of NPP to doubled CO2 for all three models. In contrast, there are different relationships between temperature and the response of NPP to doubled CO2 for the three models: there is a negative relationship in the responses of BIOME-BGC, no relationship in the responses of Century, and a positive relationship in the responses of TEM. In BIOME-BGC, the NPP response to doubled CO2 is controlled by the change in transpiration associated with reduced leaf conductance to water vapor. This change affects soil water, then leaf area development and, finally, NPP. In Century, the response of NPP to doubled CO2 is controlled by changes in decomposition rates associated with increased soil moisture that results from reduced evapotranspiration. This change affects nitrogen availability for plants, which influences NPP. In TEM, the NPP response to doubled CO2 is controlled by increased carboxylation which is modified by canopy conductance and the degree to which nitrogen constraints cause down-regulation of photosynthesis. The implementation of these different mechanisms has consequences for the spatial pattern of NPP responses, and represents, in part, conceptual uncertainty about controls over NPP responses. Progress in reducing these uncertainties requires research focused at the ecosystem level to understand how interactions between the carbon, nitrogen, and water cycles influence the response of NPP to elevated atmospheric CO2.

    Notes: Summary Time-consuming calorimetry is not necessary to determine energy allocation patterns in populations of plants with primarily carbohydrate seed reserves. In four ecologically diverse species there is no significant difference between energy allocation patterns based on calories and on dry weights of plant parts. Significant energy allocation differences among species and among populations of one species are reflected equally well by caloric and dry weight measures.

    Notes: Summary Ramets of the understory herb, Aster acuminatus, were transplanted from two source populations into eight understory garden sites that varied in light and soil moisture levels. Ramet growth, clonal growth, flowering and survivorship were monitored for three growing seasons. Large differences among gardens in ramet growth, clonal growth and flowering developed in the first growing season and increased in the next two years. This variation was positively correlated with garden light level but not at all with soil moisture. Mortality rates were low in all gardens and showed that genets from any particular source could survive over a broad range of environmental conditions. There was no conclusive evidence for any source population differences in the capacity to survive or grow in different environments. The rapid, light-induced responses of transplanted ramets resulted in garden populations very similar in appearance to natural populations experiencing similar light regimes. These results combined with those from other studies of A. acuminatus provide strong evidence for the importance of light in explaining population patterns and dynamics in this species.

    Notes: Abstract We undertake a synthesis of the most relevant results from the presentations at the meeting “Plant-Soil Carbon Below-Ground: The Effects of Elevated CO2” (Oxford-UK, September 1995), many of which are published in this Special Issue. Below-ground responses to elevated [CO2] are important because the capacity of soils for long-term carbon sequestration. We draw the following conclusions: (i) several ecosystems exposed to elevated [CO2] showed sustained increased CO2 uptake at the plot level for many years. A few systems, however, showed complete down-regulation of net CO2 uptake after several years of elevated [CO2] exposure; (ii) under elevated [CO2], a greater proportion of fixed carbon is generally allocated below-ground, potentially increasing the capacity of below-ground sinks; and (iii) some of the increased capacity of these sinks may lead to increased long-term soil carbon sequestration, although strong evidence is still lacking. We highlight the need for more soil studies to be undertaken within ongoing ecosystem-level experiments, and suggest that while some key experiments already established should be maintained to allow long term effects and feedbacks to take place, more research effort should be directed to mechanisms of soil organic matter stabilization.

    Notes: Abstract Wild salt tolerant plants, halophytes, could be grown on 130×106 ha of potentially arable land in the world's coastal deserts, inland salt deserts and areas of secondary salinization in irrigation districts. Halophytes have potential as biomass crops to directly sequester up to 0.7 Gt C, similar to tree plantations, or they can play an indirect role in absorbing C from the atmosphere by providing food, fodder and energy crops from a new land base. To the extent new cropland can be developed from unused saline land, further land clearing and loss of C storage in forest fallow and old growth forests can be spared, thereby adding to the carbon sequestering potential of all usable ecosystems.
