Molecular characterisation of post-fire naturally regenerated populations of ma...

Wildfires act as a selection force threatening the sustainability and diversity of forest genetic resources. Few studies have investigated the genetic effects of forest wildfires. Species with perennial canopy seed banks in serotinous cones and soil or with long-distance seed and pollen dispersion can preserve genetic diversity and population differentiation under normal fire regimes. To test this hypothesis, w...

Impact of fire recurrence and induced water stress on seed germination and root...

Climate change will increase the frequency of drought, heat waves, and wildfires. We intended to analyse how fire recurrence and/or induced water stress can affect seed germination and root cell division in Pinus pinaster Aiton. Seeds from stands with no prior fire history and from post-fire regeneration (in areas burnt once, twice, and thrice) in northern Portugal were germinated in distilled water (control) a...

A national e-Delphi towards the measurement of safe medication practices in Por...

Objectives: To determine the face and content validity of items for measuring safe medication practices in Portuguese hospitals. Methods: 128 items were drafted from content analysis of existing questionnaires and the literature, employing preferred terms of the WHO International Classification for Patient Safety (Portuguese version). A two-round e-Delphi was convened, using a purposive multidisciplinary panel....

Physical, chemical and mechanical properties of Pinus sylvestris wood at five s...

The reduction of resinous species in Portuguese forest areas has caused constraints to wood industry supplies. Portugal represents the extreme southwest of Scots pine (Pinus sylvestris) natural distribution and large gaps exist in the knowledge of its wood-quality characteristics. Understanding the relationship between these traits is important for recognizing which combination of wood properties is the most su...

A comprehensive assessment of the transcriptome of cork oak (Quercus suber) thr...

Background: Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic inform...

Caso Sério: Elaboração de uma colecção literária de crime real

Trabalho de Projecto apresentado para cumprimento dos requisitos necessários à obtenção do grau de Mestre em Edição de Texto; O presente projecto tem como objectivo a elaboração e apresentação de uma colecção literária de “crime real”. Este é um género de não ficção em que o autor examina um crime e constrói uma narrativa sobre as acções das pessoas envolvidas no caso. Tendo em conta a fraca representatividade ...

Does selecting for improved growth affect wood quality of Pinus pinaster in Por...

The selection criteria for the first generations in the Portuguese Pinus pinaster improvement program have been the growth rate and form traits. In this work we study the consequences of this selection on wood quality traits. This study assesses genetic and phenotypic correlation between growth, wood density components, lignin content and mechanical traits (radial modulus of elasticity and radial modulus of rup...
