Abstract:
Potential consequences of climate change on crop production can be studied using mechanistic crop simulation models. While a broad variety of maize simulation models exist, it is not known whether different models diverge on grain yield responses to changes in climatic factors, or whether they agree in their general trends related to phenology, growth, and yield. With the goal of analyzing the sensitivity of simulated yields to changes in temperature and atmospheric carbon dioxide concentrations [CO2], we present the largest maize crop model intercomparison to date, including 23 different models. These models were evaluated for four locations representing a wide range of maize production conditions in the world: Lusignan (France), Ames (USA), Rio Verde (Brazil) and Morogoro (Tanzania).
While individual models differed considerably in absolute yield simulation at the four sites, an ensemble of a minimum number of models was able to simulate absolute yields accurately at the four sites even with low data forcalibration, thus suggesting that using an ensemble of models has merit. Temperature increase had strong negative influence on modeled yield response of roughly 0.5 Mg ha1 per °C. Doubling [CO2] from 360 to 720 lmol mol1 increased grain yield by 7.5% on average across models and the sites. That would therefore make temperature the main factor altering maize yields at the end of this century. Furthermore, there was a large uncertainty in the yield response to [CO2] among models. Model responses to temperature and [CO2] did not differ whether models were simulated with low calibration information or, simulated with high level of calibration information. MenosAbstract:

Teratosphaeria nubilosa severely affects young plantations of Eucalyptus globulus and E. maidenii in Uruguay. This work analyzes the
effect of this pathogen on the growth and survival of both species, based on data from a naturally infected field trial. The degree of defoliation was quantified at 21 months old, and its effects on diameter and mortality were evaluated at 62 months old. Defoliation in E. globulus was higher than in E. maidenii, with an average of 52.5 and 28.8%, respectively. Four years after the epidemic, defoliation classes of 40% or higher had significant growth losses on E. globulus, while losses in E. maidenii were significant when defoliation was 30% or higher. An average loss in DAP of 27.5 % in E. globulus and 12.5 % in E. maidenii was observed. The most affected trees, with 70-80% of defoliation in E. globulus and 60% in E. maidenii, had similar growth loss in both species, suffering a reduction in DAP of 43.9% and 42.5%, respectively. By contrast, the average mortality that occurred between 21 and 62 months old was significantly higher in E. globulus (16.7%) than in E. maidenii (3.3%). Mortality in the higher defoliation classes reached 44.7% on E. globulus and 47.1% on E. maidenii. Although E. globulus showed greater susceptibility to the disease and higher productivity losses, the significant defoliation and growth losses registered in E. maidenii suggest that this species is not as suitable as previously thought to replace E. globulus on sites with high risk of T. nubilosa.
