Antioxidant and antimicrobial activity characteristics of seven biopreparations...
Simões, Joana; Peleja, Ana; Neves, Cláudia M.B.; Costa, Daniela V.T.A.; Correia, Helena Esteves; Pinto, António; Wessel, Dulcineia; Delgado, F.M.G.Agroecological transition is a major societal challenge and it is urgent to support technical solutions to answer farmers demand towards the necessary changes. The project RESTORE - biopReparados Em SisTemas prOdução agRoEcológicos aimed to study and validate the production, conservation, and use of seven biopreparations by characterizing and testing them in lettuce nurseries. The biopreparations used include p...
Recognizing diversity to enable an agroecological transition: understanding the...
Pereira, Inês Costa; Aguiar, Ana A.R.M.; Delgado, F.M.G.; Costa, Cristina A.The agroecological transition of family farms in Portugal poses a significant challenge within the framework of the Common Agricultural Policy (CAP) and the European Green Deal. Despite their multifunctional contributions to rural territories, family farms—particularly smallholders—remain structurally disadvantaged by policy frameworks that continue to favor large-scale, high-input agricultural models. This stu...
Reproductive toxicity assessment of four portuguese plant hydrolates: Effects o...
Dias, Sandra D.F.; Andrade, L.P.; Rolo, Joana; Gaspar, Carlos; Ruivo, Patrícia Gomes; Oliveira, Ana Sofia; Ferreira, Sandra SaraivaExtracts of aromatic medicinal plants have been extensively studied regarding their numerous bioactivities. However, despite being highly used by humans, studies on the safety of these extracts for animal use are scarce. In this study, we aim to contribute to the determination of the safety profile of plant extracts by focusing on the reproductive toxicity of hydrolates (a by-product of essential oils productio...
Labdanum resin from Cistus ladanifer L. as a source of compounds with anti-diab...
Frazão, David F.; Delgado, F.M.G.; Gonçalves, José Carlos; Gomes, Carlos Martins; Sosa Diaz, Teresa; Silva, Amélia M.Labdanum resin or “gum” can be obtained from Cistus ladanifer L. by two different extraction methods: the Zamorean and the Andalusian processes. Although its main use is in the fragrance and perfumery sectors, ethnobotanical reports describe its use for medicinal purposes in managing hyperglycemia and mental illnesses. However, data concerning the bioactivities and pharmacological applications are scarce. In th...
Humulus lupulus aqueous extract and hydrolate as a potential ingredient for cos...
Valente, João Vasco; Oliveira, Rita Palmeira de; Guiomar, Liliana; Vaz, Cátia; Rolo, Joana; Gaspar, Carlos; Oliveira, Ana Sofia; Caramelo, DéboraHumulus lupulus extracts have in their composition different molecules, such aspolyphenols, α-acids, β -acids, and hydrocarbons, which contribute to the plant’s medicinal properties. These molecules are associated with antimicrobial, antioxidant, and anti - inflammatory activities. OBJECTIVE This work focuses on the evaluation of H. lupulus biological activities, with the aim of evaluating its potential for inc...
Biostimulants in organic vegetable nurseries: Study case in lettuce
Simões, Joana; Marmota, Carolina; Moreira, Lisa; Costa, Daniela V.T.A.; Correia, Helena E.; Pinto, António; Wessel, Dulcineia; Delgado, F.M.G.In order to create better conditions to achieve food safety and sovereignty, agroecology, as a science, looks for solutions for several steps of the technical itineraries of the crops. Crop nutrition and protection are two main crop itinerary components that have been in the center of farmers challenges and consumers concerns, and biopreparations, which have been prepared using natural substances, have been use...
Logística na fileira PAM em Portugal. Proposta para a criação de um modelo
Almeida, C.A.M.; Alberto, D.; Delgado, F.M.G.; Martins, Manuel; Carneiro, J.P.; Neto, Diana Filipa de JesusO presente estudo enquadra-se na atividade do projeto PAM4wellness, "elaboração de estudos, pesquisas e diagnósticos", correspondendo à subactividade c) "Organização, Logística e Distribuição-definição de um modelo de organização adaptado ao setor PAM", através do qual se pretende contribuir para a resposta a uma das necessidades manifestadas, tanto em fontes bibliográficas como diretamente por agentes no terre...
Multitemporal land use and cover analysis coupled with climatic change scenario...
Almeida, Alice; Delgado, F.M.G.; Roque, Natália; Ribeiro, M.M.A.; Fernandez, Paulo: Climate change and land use and land cover (LULC) change are impacting the species’ geographic distribution, causing range shifts and reducing suitable habitats. Asphodelus bento-rainhae subsp. bento-rainhae (AbR) is an endangered endemic plant restricted to Serra da Gardunha (Portugal), and knowledge of those changes will help to design conservation measures. MaxEnt was used to model AbR’s current distributi...
Mediterranean lavenders from section stoechas : an undervalued source of second...
Domingues, Joana Lopes; Zuzarte, Mónica; Duarte, Ana Paula; Delgado, F.M.G.; Gonçalves, José CarlosGlobally, climate change and wildfires are disrupting natural ecosystems, thus setting several endemic species at risk. The genus Lavandula is widely present in the Mediterranean region and its species, namely, those included in the section Stoechas, are valuable resources of active compounds with several biological assets. Since ancient times lavenders have been used in traditional medicine and for domestic pu...
Rockrose land management : contribution of periodic harvesting to increase valu...
Frazão, David F.; Gonçalves, José Carlos; Silva, Amélia M.; Delgado, F.M.G.: Cistus ladanifer L. (Cistaceae) occupies extensive areas as a dominant species (shrublands) or is associated to other major forest typologies in the Iberian Peninsula. Cistus ladanifer shrublands are mostly present in oligotrophic lands with little valorisation and management and as they develop over the years (up to 20-years-old) they promote the ignition and perpetuation of fire. To contribute to the proper...
