Moon jellies are some of the most popular, widely distributed, and best-studied marine jellyfish. By the end of the past century only two or three Aurelia species were recognized, but with the rise of DNA barcoding studies, around thirty Aurelia species are presently accepted. Most of the species are morphologically indistinguishable and have restr...

The fried egg jellyfish Phacellophora camtschatica (senso lato) is a morphologically peculiar and conspicuous species occurring mostly in the cold waters of the North Pacific. It is less common in the cold waters of the NW Atlantic, and occasionally has been reported in the Mediterranean, Arctic, East and South Pacific, and E, SW and NE Atlantic. H...

Changes occurring in seven chestnut (Castanea sativa sp.) cultivars, caused by boiling and roasting, on starch content, cell and starch granules dimension were evaluated, and morphological changes were characterized by scanning electron microscopy. Three clear patterns of variation were detected after processing, namely: i) decrease of starch conte...

Description of plant communities has been largely based on phytossociolgical methods, analyzed using ordination and cluster techniques, and based on species with indicator value. Although Bayesian methods have been progressively more used in ecology, genetics and phylogeny, their use in community studies has not been equally developed. Here we illu...

The 2011 post-symposium excursion was conducted in northern mainland Portugal and a ended by 10 entomologists from 5 countries. Primarily day collecting was performed in more than a half dozen natural areas with diverse elevations, vegetation types and climates, but was most productive in Peneda-Gerês National Park, the Marão Mountains, Douro Inter...

In order to characterise the changes produced by boiling and roasting on the mechanical properties of 11 Portuguese chestnut cultivars (cvs.), the moisture, mass, force and energy required as well as shell and kernel stiffness of raw, boiled and roasted chestnuts were evaluated. In comparison to raw chestnuts, boiling increased the moisture content...

INTRODUÇÃO A ilha de Santa Maria é a mais antiga dos Açores apresentando extensas formações de origem sedimentar (com mais de 8 milhões de anos) onde se podem encontrar fósseis marinhos. A região Ocidental aplanada, baixa, com solos argilosos e clima seco contrasta com a região Oriental, acidentada e sujeita à formação de nuvens e de precipitação e...
