Arthropods are important components of the soil fauna in improving soil quality and its structural properties. Arthropods are also very sensitive to soil management practices. Thus, a study was carried out in a vineyard in the Douro Demarcated Region (Northeast Portugal), to investigate the effect of three soil management practices (tillage, ground cover with spontaneous vegetation, and ground cover with sown v...
O presente trabalho realizado no âmbito do projecto “EcoVitis: Maximização dos Serviços do Ecossistema Vinha na Região Demarcada do Douro” teve por objectivo avaliar a influência do enrelvamento natural, enrelvamento semeado e mobilização na entrelinha, na diversidade dos artrópodes do solo na vinha. A parte experimental decorreu na Quinta do Casal da Granja, propriedade da Real Companhia Velha. Procedeu-se ao ...
Pterospartum tridentatum Willk. is an autochthonous and common plant in Portugal, locally known as ‘carqueija’. Leaves and stems are normally used in cooking, to flavour rice, roast meat or hunting animals and leaves are also used as condiment in fresh salads. Despite its traditional use, no evaluation in mitochondrial bioenergetics has been performed. P. tridentatum leaf extract phenolic composition was elucid...

It is know that cyanobacterial taxonomic groups are characterized by particular lipid patterns that can be used as their biological markers. The present study examined the fatty acid composition of nostocacean heterocystous cyanobacterial strains isolated from Central-western Portuguese freshwater shallow water bodies, namely Vela Lake and rice fields from Mondego River Basin. Morphological characterization sho...
En el presente trabajo se hace mención a diferentes taxones específicos e infraespecíficos con distribuciones diversas en el territorio portugués continental. En este sentido, la intensa variabilidad geomorfológica y la intrincada bioclimatología del Norte de Portugal constituyen, ambos, factores ambientales decisivos para comprender el comportamiento florístico de esta parte del país. Los taxones analizados en...
The taxonomical composition and an analysis of four ecological characteristics of the 46 endemic species occurring in the lower Duero Basin (CW Iberian Peninsula) have been made. A comparative analysis of the results reveals that this endemic flora does not comply with the general patterns previously observed in other floras. Predominant life forms are hemicryptophytes (43%) and chamaephytes (22%). As far seed-...
