The Vineyard Microbiome: How Climate and the Main Edaphic Factors Shape Microbi...
Silva, Vanessa; Brito, Isabel; Alexandre, AnaThe soil microbiome is a complex system that encompasses millions of microbes including archaea, bacteria, fungi, protozoa and viruses. The role of abiotic factors is crucial in shaping the distribution patterns of microorganisms, its abundance and also the interactions between species, from local to the global level. In the particular case of the vineyard, the microbial communities have a potential impact in b...
BIOMONTADO – Montado ecosystem and vineyards
Pinto-Cruz, Carla; Belo, Anabela; Almeida, Erika; Janeiro, Carla; Brito, Isabel; Alexandre, Ana; Prats, Sérgio; Pelayos, Oscar; Pedroso, NunoThe montado is considered a high nature value (HNV) agro-silvopastoral system that provides important ecosystem services, in addition to tradable products, namely biodiversity conservation, soil conservation, carbon sequestration, organic matter storage and water cycle regulation. In the Alentejo region, its matrix is often interrupted by patches of agricultural systems, such as vineyards. The BIOMONTADO projec...
Soil Organic Matter as a Global Metric for Soil Health: Integrating Soil Biolog...
Brito, Isabel; Goss, Michael J.Soil is fundamental to sustaining life on Earth, supporting agricultural productivity, water and climate regulation and habitat for biodiversity. Increasing pressures from agricultural intensification, climate change, and land-use changes pose existential threats to our soils as well as impairing their quality or health. Both these terms are subject to considerable criticism. Consequently, accurate measurement ...
On the challenges to documenting requirements in agile software development: A ...
Canedo, Edna; Calazans, Angelica; Silva, Geovana; Masson, Eloisa; Brito, IsabelAgile Software Development (ASD) is an iterative and incremental methodology designed to accelerate project deliveries. In this dynamic environment characterized by constant changes, the task of documenting requirements becomes increasingly challenging, leading to the emergence of the technical debt issue. This research involved a survey of 84 practitioners to identify the techniques and practices employed in d...
Navigating remote work: Challenges and adaptations of agile teams amidst covid-19
Canedo, Edna; Calazans, Angelica; Silva, Geovana; Masson, Eloisa; Brito, IsabelDue to the COVID-19 pandemic, there was a massive migration from working in the office to working from home (WFH) and the software development teams had to adapt to the new reality. This paper focused on how the agile teams dealt with the challenges of WFH, faceto-face or hybrid during and after the Covid-19 pandemic and how this affected the software development process. To capture the perceptions of the agile...
Evolutionary feature selection for time-series forecasting
Linares-Barrera, Maria Lourdes; Jimenez-Navarro, Manuel J.; Riquelme, José; Martínez-Ballesteros, María; Brito, IsabelIn machine learning, feature selection is crucial for pinpointing the key subset of features that enhances interpretability and preserves or boosts the model’s original performance. Filter methods, which assess features using statistical metrics, are particularly notable. Recently, a novel metric called Conditional Dependence Coefficient has been proposed to measure the dependence between subsets of variables. ...

Silva, Flávia; Tomaz, Alexandra; Piedade, Ana; Brito, Isabel; Bruno, Luís; Azevedo, Maria Manuela; Lopes, Sandra; Baer, Isabel; Amaral, MartaThis document reports the objectives, contents, activities, methods, and recommendations related to Task 3.4 of the InovEAP project, entitled "Capacity Program for Teachers in Professional Pedagogy for Student-Centred Teaching and Learning and Strengthening Links Between Polytechnic Higher Education and Project Companies". As later detailed, the presented activities occurred between March 2022 and September 202...
Wheat Shoot Al, Fe, Mn and Zn Levels Are Influenced by Arbuscular Mycorrhiza Ex...
Faria, Jorge M.S.; Teixeira, Dora Martins; Pinto, Ana Paula; Barrulas, Pedro; Brito, Isabel; Carvalho, MárioIn the present study, the levels of Al, Fe, Mn and Zn in wheat shoots were quantified by inductively coupled plasma mass spectrometry (ICP-MS). Wheat was grown in an acidic soil with toxic levels of Mn and with intact or disrupted extraradical mycelium (ERM) as the arbuscular mycorrhizal fungi (AMF) inoculum source, resulting from the previous growth of O. compressus. In the presence of an intact ERM, toxic Mn ...
Arbuscular Mycorrhiza Extraradical Mycelium Promotes Si and Mn Subcellular Redi...
Faria, Jorge M.S.; Conceição, Taiana A; Teixeira, Dora Martins; Brito, Isabel; Barrulas, Pedro; Pinto, Ana Paula; Vaz, Margarida; Carvalho, MárioAbstract: Manganese (Mn) and aluminum (Al) toxicities are serious edaphic limitations to crop production in acidic soils. Excess Mn can be countered using a stress-adapted soil microbiota that establish symbiotic relationships with native plants. The arbuscular mycorrhizal fungi (AMF) associated with Lolium rigidum L. develop extraradical mycelia (ERM) that quickly colonize wheat and lead to greater shoot growt...
The effect of plant mycotrophy and soil disturbance on soil microbial activity
Conceição, Taiana; Michael J., Goss; Andrade, Galdino; Brito, IsabelIn cropping systems, the choices adopted for the tillage system used and plants cultivated can strongly influence the soil microbial population and its functional profile. Arbuscular mycorrhizal fungi are an important component of soil microbiome and their mutualistic symbiosis with the majority of higher plants grant the latter a wide range of benefits. The extraradical mycelium developed by these fungi expand...
