Evaluation of spontaneous and weedy flora of vineyards for ecosystem services p...
Aguiar, Francisca C.; Pires, Beatriz R.; Lopes, Carlos M.Spontaneous flora of vineyards in the Mediterranean region has lately been receiving much attention, due to the increasing awareness of their benefits for agroecosystems, soils, and for provisioning multiple Ecosystem Services (ES). However, initiatives for valuing flora often clash with the potential losses by interference with vines, but in an extent difficult to evaluate. We developed the index VIFLORES – VI...

Agricultural practices for biodiversity enhancement: evidence and recommendatio...
Marcelino, Sara M.; Gaspar, Pedro Dinis; do Paço, Arminda; Lima, Tânia M.; Monteiro, Ana; Franco, José Carlos; Santos, Erika S.; Campos, RebecaAgricultural expansion and intensification worldwide has caused a reduction in ecological infrastructures for insects, herbaceous plants, and vertebrate insectivores, among other organisms. Agriculture is recognized as one of the key influences in biodiversity decline, and initiatives such as the European Green Deal highlight the need to reduce ecosystem degradation. Among fruit crops, grapes are considered one...
Towards sustainable agriculture: A critical analysis of agrobiodiversity assess...
Marcelino, Sara M.; Gaspar, Pedro Dinis; do Paço, Arminda; Lima, Tânia M.; Monteiro, Ana; Franco, José Carlos; Santos, Erika S.; Campos, RebecaAgriculture intensification has driven the loss of biodiversity at a global level. The imple- mentation of strategies to conserve and promote biodiversity in agricultural areas can be favoured by adequate assessment methods that foster the awareness of decision makers about the impact of management practices. This paper presents a state-of-the-art review of assessment methods of the overall biodiversity in agri...
Using the fraction of transpirable soil water to estimate grapevine leaf water ...
Egipto, Ricardo; Costa, J. Miguel; Silvestre, José; Lopes, Carlos M.Context and purpose of the study – Weather uncertainty is forcing Mediterranean winegrowers to adopt new irrigation strategies to cope with water scarcity while ensuring a sustainable yield and improved berry and wine quality standards. Therefore, more accurate and high-resolution monitoring of soil water content and vine water status is a major concern. Leaf water potential measured at pre-dawn (YPD) is consid...
Image based vineyard yield prediction using empirical models to estimate bunch ...
Victorino, Gonçalo; Lopes, Carlos M.Context and purpose of the study - Vineyard yield estimation brings several advantages to the entire wine industry. It can provide useful information to support decision making regarding bunch thinning practices, harvest logistics and marketing strategies, as well as to manage stored wine and cellar tanks allocation. Today, this estimation is performed mainly using manual methods based on destructive bunch samp...
Modulation of the berry skin transcriptome of cv. tempranillo induced by water ...
Carvalho, Luisa C; Ramos, Miguel J. N.; Faísca-Silva, David; Marreiros, Pedro; Fernandes, João C.; Egipto, Ricardo; Lopes, Carlos M.; Amâncio, SaraClimate change in the Mediterranean area is making summers warmer and dryer. Grapevine (Vitis vinifera L.) is mostly important for wine production in Mediterranean countries, and the variety Tempranillo is one of the most cultivated in Spain and Portugal. Drought decreases yield and quality and causes important economic losses. As full irrigation has negative effects on quality and water is scarce in this regio...
Evaluation of a deep learning approach for predicting the fraction of transpira...
Alibabaei, Khadijeh; Gaspar, Pedro D.; Campos, Rebeca M.; Rodrigues, Gonçalo C.; Lopes, Carlos M.As agriculture has an increasing impact on the environment, new techniques can help meet future food needs while maintaining or reducing the environmental footprint. Those techniques must incorporate a range of sensing, communication, and data analysis technologies to make informed management decisions, such as those related to the use of water, fertilizer, pesticides, seeds, fuel, labor, etc., to help increase...

A review of the challenges of using deep learning algorithms to support decisio...
Alibabaei, Khadijeh; Gaspar, Pedro D.; Lima, Tânia M.; Campos, Rebeca M.; Girão, Inês; Monteiro, Jorge; Lopes, Carlos M.Deep Learning has been successfully applied to image recognition, speech recognition, and natural language processing in recent years. Therefore, there has been an incentive to apply it in other fields as well. The field of agriculture is one of the most important fields in which the application of deep learning still needs to be explored, as it has a direct impact on human well-being. In particular, there is a...
