Anthelmintic resistance has been documented worldwide, but few cases have been reported in dogs. Shelter dogs are a great opportunity to study intestinal helminths and assess their potential resistance to anthelmintic compounds. With these two goals in mind, 361 faecal samples were collected from dogs in 18 municipalities in Portugal, from 19 shelters and 11 private tutors. These samples were analysed using the...
A compreensão da distribuição do carbono da biomassa microbiana (CBM) metabolicamente ativa nos solos vitícolas é fundamental para determinar o balanço de carbono em viticultura sustentável e para integrar estas determinações em análises de rotina que permitam avaliar o impacto de práticas de gestão sustentável do solo. O carbono da biomassa microbiana foi determinado em três datas correspondentes aos estados f...
The crop water stress index (CWSI) is a widely used analytical tool based on portable thermography. This method can be useful in replacing the traditional stem water potential method obtained with a Scholander chamber (PMS Model 600) because the latter is not feasible for large-scale studies due to the time involved and the fact that it is invasive and can cause damage to the plant. The present work had three o...
In the Vinhos Verdes wine region, the largest Protected Designation of Origin (PDO) region in Portugal, the most common ‘Alvarinho’ training system is single downward shoot positioning (DSP), which is currently being replaced by vertical shoot positioning (VSP). This work aimed to evaluate physiological and productive parameters of ‘Alvarinho’ grapevines in both training systems. This study was carried out in 2...
Viticultural zoning studies that support the definition of terroir units general follow two main approaches of geographic differentiation related either to: a) land capability or vineyard suitability, or b) grape, grapevine or wine characteristics. Both approaches are commonly considered in the definition of terroir at regional and local approaches. The purpose of this preliminary study was to develop and apply...
