Global synthesis of apple pollination research highlights general pollen limita...
Eeraerts, Maxime; Osterman, Julia; Batáry, Péter; Klein, Alexandra-Maria; Albrecht, Matthias; Andersson, Georg; Báldi, András; Bernauer, OliviaABSTRACT: Apple is one of the most important pollinator-dependent fruit crops worldwide. To secure high-quality yields, it is crucial to know which, and to what extent, pollinating insects contribute to its pollination success as measured by fruit set, fruit weight and seed set. We perform a meta-analysis of field studies conducted across multiple orchards on insect-mediated pollination in apple cultivation, us...
ADIPA: uma associação em defesa do comércio
Lousada, Maria Alexandre; Pistola, Renato; Loureiro, JoãoDar a conhecer a história e o património da ADIPA, Associação dedicada à defesa dos interesses e dos direitos dos distribuidores de produtos alimentares e afins, é o propósito deste livro que assim se junta às comemorações dos seus 50 anos de existência. Durante este meio século, a ADIPA ultrapassou dificuldades, ganhou desafios e afirmou-se como representante das empresas grossistas, e mais recentemente retalh...
Theory of change for a national pollinator strategy in Portugal
Castro, Sílvia; Loureiro, João; Shoonman, Marten; Thijssen, Martijn; Nave, Anabela; Penado, Andreia; Galveias, Adriana; Oliveira, Bárbara; Rego, CarlaABSTRACT: BACKGROUND The Theory of Change (ToC) workshops supported by Promote Pollinators Alliance aim to assist the development of pollinator strategies by building a cause-effect roadmap on how specific actions can trigger intended outcomes, and how these subsequently contribute to the desired impact, i.e., pollinator conservation. This initiative provides an opportunity for members lacking a national govern...
Teoria da Mudança para a Conservação dos Polinizadores em Portugal
Castro, Sílvia; Loureiro, João; Schoonman, Marten; Thijssen, Martijn; Nave, Anabela; Penado, Andreia; Galveias, Adriana; Oliveira, Bárbara; Rego, CarlaRESUMO: CONTEXTO Os workshops da Teoria da Mudança (TdM), promovidos pela Aliança Promote Pollinators, têm como objetivo auxiliar o desenvolvimento de estratégias para a conservação dos insetos polinizadores. Isto é alcançado através da construção de uma narrativa que estabelece relações causa-efeito entre ações específicas e resultados desejados, e como estes resultados contribuem para o impacto desejado – a c...
Sustainable futures: from causes of environmental degradation to solutions
Ferreira Fernandes, Carla Sofia; Alves, Fátima; Loureiro, JoãoThe impacts of climate change, loss of biodiversity and pollution influence the living experiences of the various members of communities that rely on agriculture, shaping the adaptation responses to those phenomena and actions towards sustainable development. This study aims to understand how members of rural communities in Morocco perceive the causes of environmental degradation and the solutions meant to supp...
Ploidy effects on the relationship between floral phenotype, reproductive inves...
García-Muñoz, Ana; Ferrón, Camilo; Vaca-Benito, Celia; Loureiro, João; Castro, Silvia; Muñoz-Pajares, A Jesús; Abdelaziz, MohamedPremise: The relationships between reproductive investment, phenotype, and fitness have been broadly studied in cross‐pollinated plants in contrast to selfing species, which are considered less interesting in this area because they are supposed to be a dead end in any evolutionary pathway. Still, selfing plants are unique systems to study these questions since the position of reproductive structures and traits ...
Towards continuous non-invasive blood pressure measurements-interpretation of t...
Loureiro, João; Bogatu, Laura; Schmitt, Lars; Henriques, Jorge; Carvalho, Paulo; Noordergraaf, Gerrit J.; Paulussen, Igor; Muehlsteff, JensBlood pressure (BP) surrogates, such as pulse transit time (PTT) or pulse arrival time (PAT), have been intensively explored with the goal of achieving cuffless, continuous, and accurate BP inference. In order to estimate BP, a one-point calibration strategy between PAT and BP is typically used. Recent research focuses on advanced calibration procedures exploiting the cuff inflation process to improve calibrati...
Ecological niches in the polyploid complex Linum suffruticosum s.l
Afonso, Ana; Castro, Silvia; Loureiro, João; Arroyo, Juan; Figueiredo, Albano; Lopes, Sara; Castro, MarianaIntroduction: The high frequency of polyploidy in the evolutionary history of many plant groups occurring in the Mediterranean region is likely a consequence of its dynamic paleogeographic and climatic history. Polyploids frequently have distinct characteristics that allow themto overcome the minority cytotype exclusion. Such traits may enable polyploid individuals to grow in habitats different from their paren...
Impact of genome duplications in drought tolerance and distribution of the dipl...
Castro, Helena; Dias, Maria Celeste; Castro, Mariana; Loureiro, João; Castro, SilviaPolyploidy has important ecological effects, including ploidy-mediated effects on morphology, breeding system and ecological tolerances. However, there is still little comprehensive research available to test its adaptive significance and its role in driving distributional patterns. This work aimed to assess the contribution of genome duplications to ecological divergence using an experimental approach with the...
Video abstract production guide
Ferreira, Miguel; Lopes, Betina; Granado, António; Siopa, Catarina; Gaspar, Hugo; Castro, Helena; Castro, Silvia; Loureiro, JoãoVideo abstracts are audio-visual representations of a scientific abstract that a researcher can use to complement an article. As a science communication tool, they stand as a novel and exciting way to present scientific discoveries, explore new formats, and reach new audiences. In this practice insight, we share the experience of creating a video abstract in Ecology, explaining and exemplifying the dierent stag...
