Latest developments in mass spectrometric analysis and > sample preparation for carbon, oxygen, hydrogen and nitrogen will be set > against the theory underlying fractionation and implications for primary > production of organic material. The transformations associated with the > hydrological cycle, soils and vegetation will be compared for a range of > ecosystems. Ultimately, the aim is to validate models of resource > acquisition and turnover in terrestrial and aquatic ecosystems, producing > a sounder basis for palaeoclimatic reconstruction and more reliable > predictions for future climate change. > Provisional programme: > Monday 8 July > 12:00 Excursion to Hadrians Wall and the Whin Sill > 17:00-18.30 Registration at Castle Leazes Halls of Residence > Tuesday 9 July > 08:15 REGISTRATION AT CURTIS AUDITORIUM (Buses are available to take > delegates from Castle Leazes to Curtis Auditorium at 08:30 Tues-Thurs) > > Session 1: STABLE ISOTOPES, Introduction and technical > development > Keynote lecture:J RAVEN Palaeoatmospheres and > the evolution of phototrophy > Manufacturers presentations:FINNEGAN, FISONS VG, > EUROPA SCIENTIFIC, ANALYTICAL PRECISION > > Session 2: Sources: inorganic and organic transformations > J T BRENNA GCC-IRMS for organic hydrogen > J VOLKMAN Isotopic analysis of hydrocarbons from a permian shale > R EVERSHED Compound distributions and d13C of modern and fossil leaves > G GLEIXNER Origin of refractory organic acids in aquatic ecosystems. > M COLEMAN Interactions of inorganic and microbial systems. > G FARQUHAR Interpretation of d18O of leaf material > J SCHLEUCHER Intramolecular deuterium distributions and plant growth > conditions > K FREEMAN Carbon 13 plant lignin records and Quaternary climate variations > D HOPKINS & D ROBINSON Stable isotopes in studies of nitrogen fluxes in > and from soils > L HANDLEY Nitrogen sources and sinks > T YONEYAMA Nitrogen fractionation during plant uptake and assimilation > > AAB Reception and poster session > CONFERENCE DINNER > > Wednesday 10 July > Session 3: Terrestrial resources and transformations:soil, nutrient and > water sources > > H SCHMIDT 13C patterns in natural compounds and enyzme catalysed reactions > G GEBAUER NH4+ and NO3- use by forest plants: effect on soils/ground water > J RICHARDS 15N and bladderworts > P ERSKINE Plants, penguins and 15N: N pathways on a subantarctic island > C KENDALL Use of d18O and d15N to detect sources of nitrate in early > spring run off > T DAWSON H and O isotope analyses and plant water relations > D M SMITH Water competition between trees and crops in agroforestry > J MAGID Plant litter decomposition in a tropical ultisol: a dual isotopic > study in 13C and14C > R AMUNDSON Relationship between d18O of soil CO2 and water > J GAT Stable isotopes and the hydrological cycle > > Session 4 Through plant to terrestrial ecosystems > D YAKIR Leaf water, a cross road for plant associated isotopic signals > E PENDALL Isotopic tracers of water movement through the soil-plant- > atmosphere continuum > E BRUGNOLI Carbon isotope discrimination in stuctural and non-structural > carbon: adaptation to unfavourable conditions > J EHLERINGER Integration of arid zone ecosystems using stable isotope > L FLANNAGAN Oxygen isotope effects during CO2 exchange: from leaf to > ecosystem processes > B KRUIJT Do we need isotopes to estimate carbon recycling in plant canopies? > J R BROOKS Leaf d13C of boreal plants: functional groupings of life forms > J M GUEHL Diversity in tree species of an Amazonian rainforest: a > dualisotope approach (d13 C and d15N) > N BUCHMANN Carbon isotope discrimination of terrestrial ecosystems > > POSTER SESSION > GALA DINNER AT CIVIC CENTRE > > Thursday 11 July > Session 5: Aquatic ecosystems > A JOHNSTON & H KENNEDY Modelling carbon acquisition & isotopic > composition in phytoplankton > N OWENS Nitrogen cycling in oceans > S BURY C & N biogeochemical cycling in coastal waters off South Georgia, > Antarctica > D DES MARAIS Marine cyanobacterial mat ecosystems: isotopic > discriminationin carbon & sulphur biogeochemical cycles > H SPERO Effects of seawater chemistry on oxygen and carbon isotopic > composition of biogenic calcite > F A STREET-PERROTT, Y HUANG & G EGLINTON 'Heavy carbon' in lake sediments > and peat during the last glaciation > P WACHNIEW Controls on isotopic composition of calcite precipitating in > lake Gosciaz > M JEDRYSEK Mechanisms of methanogenesis in freshwater sediments > > Session 6: Climate change and atmospheric processes > A FALLICK Carbonates and development of life > J MARSHALL Carbon isotope ratios & stomatal densities of Miocene fossil > leaves and modern congeners > D BEERLING Changes in land-plant function over the Phanerozoic > T CERLING Calcretes and the evolution of photosynthetic pathways > G KLINKEN Determining ancient human diet: are plants the key? > M POLLARD Stable isotopes in archaeology > V R SWITSUR Stable isotopes in tree ring cellulose > H MEIJER 18O of CO2 - direct signal of the global biosphere > P CIAIS Integration of 13C and 18O in atmospheric transport models > > Howard -- Looks just great . I shall be sorry to miss it : i could have learnt a lot. But BOREAS COMES FIRST!! (Ican't underdtand how Jim and Larry can be away during the main IFC!!) Paul >
