On a coal specimen possibly associated with the classical Mio-Pleistocene São J...

Due to the unusual presence of coal seams within a volcanic island, the São Jorge lignite, located in the north side of Madeira Island, was since the early 19th century a magnet for naturalists. In 1854 the site was visited by Sir Charles Lyell and Georg Hartung, where both discovered a leaf-bed associated with the lignite. This finding pro vided key proofs to Lyell's uniformitarian theory of the formation of v...

Exploring agrivoltaics: Opportunities, trade-offs and potential solutions – int...

Achieving carbon neutrality relies on renewable energy infrastructures like hy-drological dams, photovoltaic arrays, and wind parks, often in agriculturally uti-lized areas. Despite their crucial role in achieving carbon neutrality while main-taining socio-economic growth, these infrastructures necessitate careful consid-eration of their impacts on land systems to achieve net emissions savings. Under-standing t...

Genetic diversity and conservation of the Madeira Island (Portugal) endemic Ger...

Geranium maderense is a perennial, monocarpic herb, up to 200 cm tall, producing very showy inflorescences, very rare in the wild, although cultivated throughout the world as an ornamental plant. G. maderense is protected under the EC habitats directive (Annex *B-II, IV) and Bern Convention (Annex I) only found, so far, in two cliff associated sites, and classified as a Critically Endangered species (IUCN). Usi...

Coronamellitus: An Infecto-Metabolic Pandemic

Introduction: There are considerable differences in mortality due to SARS-CoV-2 infection. Advanced age and comorbidities, such as diabetes mellitus, have been associated with a worse prognosis. The aim of this study was to assess the impact of diabetes and metabolic control on Emergency Department (ED) admission in patients with COVID-19 with hospitalization criteria. Methods: Clinical and laboratorial feature...

Trees as habitat islands: temporal variation in alpha and beta diversity in epi...

Aim: Trees represent striking examples of habitat islands, with various degrees of spatial isolation and evolving properties during their life cycle. Here, we investigate whether changes in habitat conditions, dispersal limitations or competition cause variation in patterns of epiphytic species richness and turnover. Location: Madeira island. Taxon: Bryophytes. Methods: Using linear mixed effect models, we test...

Biologia, paisagem e diversidade

O novo catálogo da vegetação portuguesa (Continente, Açores e Madeira): descriç...

In this work we propose a syntaxonomic scheme, according to the Code of Phytosociological Nomenclature for the vegetation of Portugal: continental and the Azores and Madeira archipelagos. The scheme encompasses 827 associations (4 communities), 245 alliances, 116 orders, and 64 vegetation classes. The 58 suballiances, 2 suborders and 4 subclasses, are also mentioned, as auxiliary ranks. For the higher syntaxa d...

PLANTS COMMUNITIES OF VASCULAR PLANTS OF MAINLAND PORTUGAL, AZORES AND MADEIRA

In this paper we mean the 830 associations, 239 alliances, 116 orders, and 63 phyosociological class presents on Portugal, Azores, and Madeira Islands, we mention also the 65 subaliances, 2 suborders and 4 subclasses. The higher syntaxa to subaliance have succint description, and the characteristics species are related. The new syntax and corrections are described and listed in an annex, also presents a florist...

Guillain-Barré Syndrome: Experience of an Intensive Care Unit and literature re...

Introduction and objective:Guillain-Barré syndrome (GBS) is a historically well defined entity, however, the advance of scientific knowledge has proven to be a heterogeneous syndrome, with multiple variants, each one with distinct clinical features and specific pathophysiology. Except for theMiller-Fishervariant of GBS, it is characterized bythe absence of osteotendinous reflexes and ascending flaccid muscle pa...
