A new approach to palynostratigraphy of the middle late Famennian Gafo Formatio...

ABSTRACT: New palynological results from the Gafo Formation (southern sector of the Pulo do Lobo Domain, South Portuguese Zone) are integrated with recently studied sections and drillholes from the Portuguese and Spanish sectors. A total of 44 samples were studied, 27 of which were positive for palynomorph taxonomy. This research revealed well preserved palynological assemblages, including 73 spore species allo...

Assessment of habitat suitability for common cockles in the Ria the Aveiro Lago...

The common cockle Cerastoderma edule is a widespread bivalve species inhabiting estuarine systems across the North East Atlantic, where it provides several ecosystem services, and represents a valuable fishery resource for local economies. However, anthropogenic pressure and more frequent extreme weather events threaten the resilience of the species. Spatially explicit information on species distribution is cri...

Os primeiros fósseis do Ordovícico de Águeda (Aveiro): Implicações lito e bioes...

RESUMO: Apresentam-se os primeiros fósseis do Ordovícico de Águeda, provenientes de níveis de meta-argilitos intercalados numa sequência arenítica metamórfica de Arrancada do Vouga. A associação, moderadamente diversa, inclui trilobites [Crozonaspis cf. incerta (Deslongchamps) e Crozonaspis sp.], bivalves [Praenucula sp., Cardiolaria cf. beirensis (Sharpe), Praeleda cf. ribeiroi (Sharpe), Hemiprionodonta cf. lu...

The first Ordovician fossils from Águeda are presented, coming from dark mudstones between two sandstones successions at Arrancada do Vouga. The moderately diverse assemblage includes trilobites [Crozonaspis cf. incerta (Deslongchamps) and Crozonaspis sp.], bivalves [Praenucula sp., Cardiolaria cf. beirensis (Sharpe), Praeleda cf. ribeiroi (Sharpe), Hemiprionodonta cf. lusitanica (Sharpe), Tancrediopsis escosur...

Trophic web structure and ecosystem attributes of a temperate coastal lagoon

A high quality data collection has been carried out between 2004 and 2014 to develop the first trophic ECOPATH model for the functioning of the sub and intertidal zones of Ria de Aveiro. This schematic representation allows the characterization of the most important compartments of biomass and flows of energy representing the functioning of the ecosystem, and can be used in the fields of decision-making and man...

Assessing the state of the lower level of the trophic web of a temperate lagoon...

The main purpose of this study is to assess the state of the lower level of the trophic web of a temperate lagoon, the Ria de Aveiro (Portugal), in situations of light or nutrients limitation conditions, that may occur during extreme weather events (eventually associated to climate changes). The increase of the occurrence of extreme events (frequency, intensity and duration) is likely to globally intensify the ...

CHEMOPROPHYLAXIS OF GENITAL HERPES

Genital herpes is among the most common sexually transmitted diseases worldwide. Recurrent genital herpes is associated with major morbidity. Therefore, suppressive therapy plays an important role in the life quality of these patients. There are no established guidelines regarding the criteria for initiation of prophylactic therapy, although there is evidence for it after 6 recurrences per year. Drugs approved ...
