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:

RESUMEN:
El objetivo de este estudio fue comparar tres métodos diagnósticos de metritis y endometritis e identificar cuál de ellos puede informar con más anticipación en el período posparto. Se hizo seguimiento a 34 vacas Holstein primíparas, con similar estado corporal, peso, y manejo; entre marzo y junio 2019. Se realizaron tres revisiones a los 9, 15 y 22 días posparto (DPP). Se evaluó la descarga vaginal y cérvix mediante vaginoscopía, diámetro de cuerno uterino y grosor de endometrio mediante ecografía y % de neutrófilos polimorfonucleares (PMN) por citología endometrial con cytobrush. Al final del estudio 21 vacas se clasificaron como sanas (H) y 13 como metritis (M) según resultados de la vaginoscopía. El diámetro uterino del cuerno previamente gestado fue menor en H que en M a los 9 (38,3±1,3 vs. 42,7±2,3 mm) y 15 (32,1±1 vs 38,5±1,7mm) DPP. El grosor del endometrio fue mayor en H (5,7±0,3MM) que en M (4,7±0,3mm) a los 9 DPP. El % de PMN fue significativamente mayor a los 22 DPP (H=3±1,1 vs. M= 32±7,5), Estos datos sugieren que el útero y endometrio podrían mostrar cambios estructurales en el posparto temprano que anteceden a la diferencia de porcentaje en células Inflamatorias.
SUMMARY:
The goal of this study was to compare three diagnostic methods of metritis and endometritis to identify which one can be used with more anticipation in the postpartum period. 34 Holstein primiparous cows, with similar body condition score, weight, and management, were followed between March and June 2019. Three revisions were performed at 9, 15 and 22 days postpartum (DPP). Vaginal discharge and cervix were evaluated by vaginoscopy, uterine horn diameter and endometrial thickness by ultrasound, and % polymorphonuclear neutrophils (PMN) by cytbrush endometrial cytology. At the end of the study, 21 cows were classified as healthy (H) and 13 as metritis (M) according to vaginoscopy results. The uterine diameter of the previously gestated horn was smaller in H
than in M at 9 (38,3 ±1,3 vs. 42,7 ±2,3 mm) and 15 (32,1 ±1 vs. 38,5 ±1,7mm) DPP. The thickness of the endometrium was greater in H
(5,7 ±0,3MM) than in M (4,7 ±0,3mm) at 9 DPP. The % of PMN was significantly greater at 22 DPP (H = 3 ±1,1 vs. M = 32 ±7,5), These data suggest that the uterus and endometrium may show structural changes in the early postpartum that predate the percentage difference in inflammatory cells, MenosRESUMEN:
