Improvement of local ozone phytotoxicity modelling for autochthonous grape cult...
Blanco-Ward, Daniel; Ribeiro, A.C.; Feliciano, Manuel; Barreales, David; Paoletti, Elena; Miranda, Ana IsabelCervical cancer prevention is based on primary prevention with vaccines against Human Papillomavirus (HPV) and secondary prevention by screening with High-Risk-HPV (Hr-HPV) detection. Since 2017, cervical cancer screening in women aged 25-60 years has been performed in Portugal using Hr-HPV detection, followed by cytology in Hr-HPV-positive cases. Herein we report the prevalence of Hr-HPV genotypes and cytologi...
Exposure of mediterranean vineyards to tropospheric ozone: a modelling approach
Blanco-Ward, DanielThe main objective of this Thesis is to develop and evaluate a modeling system capable of simulating in detail the exposure and uptake of ambient ozone (O₃) by vineyards in Mediterranean environments. It also aims to contribute to the state of the art on the influence of climate in viticulture in the context of climate change. The selected study area was the Douro Demarcated Region (DDR) in Portugal. The assess...
Assessment of tropospheric ozone phytotoxic effects on the grapevine (Vitis vin...
Blanco-Ward, Daniel; Ribeiro, A.C.; Paoletti, Elena; Miranda, Ana IsabelThe grapevine (Vitis vinifera L.) is a crop with great cultural, economic and ecological relevance for Mediterranean environments besides being the fruit crop with largest acreage and economic value at the global scale. Its exposure to high levels of tropospheric ozone (O3) can result in phytotoxic effects and thus it is important to comprehensively re-evaluate these effects as well as related processes. A revi...
Validation of meteorological and ground-level ozone WRF-CHIMERE simulations in ...
Blanco-Ward, Daniel; Rocha, A.C.; Viceto, C.; Ribeiro, A.C.; Feliciano, Manuel; Paoletti, Elena; Miranda, Ana IsabelOzone is the most damaging phytotoxic air pollutant to crop yield quantity and quality. This study presents the validation of a simulation with the WRF-CHIMERE modelling system in order to assess the risk of phytotoxicity by tropospheric ozone for an important and characteristic Mediterranean crop, i.e. the grapevine. The study region was the Douro wine region in Portugal, which is characterized by a rugged rel...
Avaliação da exposição da vinha duriense ao ozono em clima presente e futuro
Isabel Miranda, Ana; Ascenso, Ana; Silveira, Carlos; Blanco-Ward, Daniel; Gama, Carla; Monteiro, Alexandra; Viceto, Carolina; Rocha, AlfredoO ozono (O3) troposférico é um gás que pode danificar severamente a vegetação. Vários estudos identificam o efeito do O3 na perda de produtividade de campos agrícolas e na redução da qualidade de produtos vegetais e frutícolas. Este artigo foca-se na Região Demarcada do Douro, uma importante região vitivinícola portuguesa, e tem como objetivo a avaliação da exposição da vinha ao O3 troposférico, mediante a apli...
Climate change impact on a wine-producing region using a dynamical downscaling ...
Blanco-Ward, Daniel; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.; Silveira, Carlos; Viceto, Carolina; Rocha, Alfredo; Ribeiro, A.C.Climate change is of major relevance to wine production as most of the winegrowing regions of the world are located within relatively narrow latitudinal bands with average growing-season temperatures (GSTs) limited to 13–21 C. This study focuses on the incidence of climate variables and indices that are relevant both for climate change assessment and for grape production, with emphasis on grapevine bioclimatic ...
Climate change potential effects on grapevine bioclimatic indices: a case study...
Blanco-Ward, Daniel; Ribeiro, A.C.; Barreales, David; Castro, João Paulo; Andrade, João Verdial; Feliciano, Manuel; Viceto, Carolina; Rocha, AlfredoIn this work, bioclimatic parameters and indices relevant to the grapevine are estimated for the years 2000 (recent-pat), 2049 (medium-term future) and 2097 (long-term future), based on very high resolution (1 km × 1 km) MPI-WRF RCP8.5 climate simulations. The selected parameters and indices are the mean temperature during the grapevine growing season period (April to October, Tgs), the cumulative rainfall duri...

Assessing the risk of tropospheric ozone phytotoxic effect on Southern European...
Blanco-Ward, Daniel; Miranda, Ana Isabel; Silveira, Carlos; Ascenso, Ana; Gama, Carla; Monteiro, Alexandra; Lopes, Myriam; Borrego, Carlos S.Tropospheric ozone in Southern Europe has an increasing tendency in association with a greater incidence of warm summers and heatwaves. As there is already much evidence of the negative effects that current ambient ozone has on vegetation, there is a need for consistent risk assessment methods. Ozone plant exposure-based parameters have been used extensively to support decision-making. However, these parameters...
