Genetic variants in oxidative stress-related genes and their impact on prognosi...
Alves, Raquel; Ventura, Filipa; Jorge, Joana; Marques, Gilberto; Coucelo, Margarida; Diamond, Joana; Oliveiros, Bárbara; Pereira, AméliaChronic myeloid leukemia (CML) is a clonal myeloproliferative neoplasia characterized by the BCR::ABL1 fusion gene, which codifies the BCR-ABL protein with increased tyrosine kinase activity. Despite the clinical results for the outstanding tyrosine kinase inhibitors (TKIs), drug resistance is a problem in CML management. Genetic variants that alter redox homeostasis by changing antioxidant enzyme expression or...
Conifers: From Seed to Sustainable Stands
Fonseca, Teresa; Gonçalves, Ana CristinaConifers have an important role in the world’s forested landscapes, holding pivotal sway over global forest areas. Their significance extends beyond mere presence, as conifers boast a remarkable array of stand structures, silvicultural systems, and diverse yields, encompassing a spectrum of valuable products and services. Understanding these features of conifers, from the nuanced characterization of their speci...
Exploring the Biometric Traits and Potential of Radiata Pine (Pinus radiata D. ...
Fonseca, Teresa; Costa, R. N. M.; Marques, C. P.; Louzada, J. L.; Gonçalves, Ana CristinaThis chapter aims to provide information on biometric traits of radiata pine (Pinus radiata D. Don) outside its natural range, considering as a case study the use of the species in Portugal. The specific objectives of this study are: i) characterising the species; ii) its management; iii) its provisioning potential. To achieve the latter, data on the biometric characteristics of radiata pine trees in Portugal w...
Restoring Mediterranean Oaks: Enhancing Conservation and Management through Net...
Fonseca, Teresa; Gonçalves, Ana Cristina; Fernandes, José Pedro; Fierravanti, Angelo; Silva, Maria EmiliaSustainably managing forests as targeted in SDG 15 requires understanding the current state of forests, the factors that constrain or threaten this sustainability, and the factors or actions that facilitate it. Monitoring the dynamics of trees and forest development, as a whole, needs to be ensured to understand the most limiting factors and promote adaptive management actions to ensure the sustainability of th...
Dynamics of biomass evaluated with remote sensing in Pinus pinaster in Portugal
Gonçalves, Ana Cristina; Sousa, AdéliaAbove ground biomass was estimated with an allometric functions with crown projection area on a per area basis, for Pinus pinaster stands in Portugal. The allometric function is a linear function with crown projection area as explanatory variable derived from the vegetation mask of high spatial resolution satellite images. It was attained with contrast split segmentation over normalized different vegetation ind...
Above ground biomass variability related to stand structure heterogeneity in ag...
Gonçalves, Ana CristinaThree forest species, cork oak (Quercus suber), holm oak (Quercus rotundifolia) and umbrella pine (for Pinus pinea), are the most representative species of the agroforestry systems in Portugal. These forest systems are characterised by low densities, large spatial variability, and have as main productions are bark and fruit for cork oak and fruit for holm oak and umbrella pine. The stand structure is diverse wi...
Influence of species traits and silvicultural practices on the regeneration of ...
Gonçalves, Ana Cristina; Barrocas, Eva; Fonseca, Teresa; Fierravanti, AngeloThe regeneration of tree species varies according to their traits, including seed production, germination, survival, and establishment, with success shaped by external factors such as predation and environmental conditions. This study investigated the regeneration patterns of Pinus pinaster and Quercus rotundifolia, focusing on their differences and similarities. The aim was to analyse the influence of the seed...
Vegetation Dynamics - Ecosystem Management, Conservation, and Protection
Gonçalves, Ana Cristina; Fonseca, Teresa FidalgoThis book entitled Vegetation Dynamics – Ecosystem Management, Conservation, and Protection has eight chapters, four related to vegetation dynamics and four related to monitoring and management. In the introductory chapter, Ana Cristina Gonçalves and Teresa Fidalgo Fonseca discussed the importance of species traits and sites in the sustainability of the forest systems as well as the importance of monitoring, mo...
Introductory Chapter: Vegetation Dynamics
Gonçalves, Ana Cristina; Fonseca, Teresa FidalgoThe assessment of species traits is of primordial importance for the sustainability of ecosystems. In addition, short and long term monitoring is essential to understand the dynamics of vegetation. This understanding, in turn, contributes to effective ecosystem management, supporting the development of alternative management approaches and thus the resilience and resistance of systems to abiotic and biotic dist...
Pseudotsuga menziesii ((Mirb.) Franco) in Portugal: A Review of Species Charact...
Fonseca, Teresa Fidalgo; Silva, M. E.; Lousada, J. L.; Luis, J. S.; Gonçalves, Ana CristinaPseudotsuga menziesii ((Mirb.) Franco), known as Douglas fir, is a prominent conifer species native to North America. It is known for its adaptability, rapid growth, and high-quality wood. It was introduced to Europe in the nineteenth century and is currently the most abundant non-native tree species cultivated in Central European forests. In Portugal, the species was initially cultivated as an ornamental plant...
