The Impact of Climate Change and Climate Extremes on Sugarcane Production
No full textWe combine the Soil-Plant-Atmosphere model with detailed timeseries measurements from experimental sugarcane plots in Guangxi, China, and São Paulo State, Brazil. We first calibrated and validated modelled carbon and water cycling against field flux and biometric data. Second, we simulated sugarcane growth under the historical climate (1980-2018), and 6 future climate projections (2015-2100). From these simulations we retrieved modelled sugarcane yield, days to reach maturity, gross primary productivity (GPP), evapotranspiration, PAR incident on the canopy, leaf area index (LAI), and soil water potential (SWP).
Next, to quantify the impact of individual climate drivers on sugarcane yield, we generated synthetic climate forcings. Within the historical climate dataset (1980-2018) we computed the mean value for each climate driver, for each year (i.e. temperature, CO2, precipitation, PAR and VPD). For each climate driver, we calculated the median of the annual means. We identified the annual timeseries corresponding to the median for each climate driver. For each climate projection, we substituted, one by one, the temperature, CO2, precipitation, PAR and VPD, with that of the median timeseries.
We then ran the model with the new synthetic climate forcings and retrieved the yield, carbon, and water flux estimates for each alternation. For each year, under each climate projection, at each site, we calculated the difference between yield, carbon, and water flux estimates under the projected and alternated-synthetic climate to compute a ‘climate effect’ of each individual climate driver.The dataset contains a file for each site (Guangxi, China and São Paulo Brazil). For each climate scenario, and each year we include model estimates of sugarcane yield, days taken to reach maturity, gross primary productivity (GPP), evapotranspiration, PAR incident on the canopy, leaf area index (LAI), and soil water potential (SWP). Estimates labelled nominal, are those simulated under the projected climate. Estimates labelled airt, CO2, precipitation, PAR and VPD, are those generated under synthetic climate forcings where the air temperature, atmospheric CO¬2, precipitation, photosynthetically active radiation, and vapor pressure deficit were alternated to the median of the historical timeseries

Charge transfer complexes and radical cation salts of chiral methylated organosulfur donors
No full textThe single crystal X-ray structure of the all-axial conformer of the (R,R,R,R) enantiomer of the chiral donor tetramethyl-BEDT-TTF (TM-BEDT-TTF) was described and compared to the all-equatorial conformer. (S,S,S,S)-Tetramethyl-BEDT-TTF formed crystalline 1 : 1 complexes with TCNQ and TCNQ-F4, as well as a THF solvate of the TCNQ complex. Donors bis((2S,4S)-pentane-2,4-dithio)tetrathiafulvalene and (ethylenedithio)((2S,4S)-pentane-2,4-dithio)tetrathiafulvalene, which contain seven-membered rings bearing chirally oriented methyl groups, only formed complexes with TCNQ-F4. The TCNQ-F4 complexes contain planar organosulfur systems, in contrast to the TCNQ complexes in which there is minimal charge transfer. A variety of crystal packing modes were observed. Electrocrystallization experiments with both enantiomers and the racemic form of tetramethyl-BEDT-TTF afforded mixed valence radical cation salts with the AsF6 and SbF6 anions formulated as (TM-BEDT-TTF)2XF6 (X = As, Sb). Electrical conductivity was only found in one charge transfer complex, while the radical cation salts are all semiconducting
