Salmonella control in poultry flocks and its public health impact
An increase in confirmed human salmonellosis cases in the EU after 2014 triggered investigation of contributory factors and control options in poultry production. Reconsideration of the five current target serovars for ... -
Sap flow of a wild cherry tree plantation growing under Mediterranean conditions: Assessing the role of environmental conditions on canopy conductance and the effect of branch pruning on water productivity
In recent decades, wild cherry has been one of the species most widely used for reforestation in Europe. Studies aiming to select and improve trees to give them the best growth rates and wood properties have increased in ... -
Schmallenberg virus detection in Culicoides biting midges in Spain: First laboratory evidence for highly efficient infection of Culicoides of the Obsoletus complex and Culicoides imicola
Since Schmallenberg disease was discovered in 2011, the disease rapidly spread across Europe. Culicoides biting midges have been implicated as putative Schmallenberg vectors in Europe. The detection of Schmallenberg virus ... -
Screening of eco-friendly thinning agents and adjusting mechanical thinning on ‘Gala’, ‘Golden Delicious’ and ‘Fuji’ apple trees
Fruit thinning is the most important yet difficult practice that drives orchard profitability. High labor costs and difficulty to improve return bloom by hand thinning have left chemical thinning as the main method used ... -
Seagrass epiphytic assemblages are strong indicators of agricultural discharge but weak indicators of host features
Wastewater pulses from rice agriculture are persistently discharged into the northern shore of the Alfacs Bay (Ebro Delta, NW Mediterranean) from April to November. The bay also receives water from coastal lagoons which ... -
Seasonal patterns of settlement and growth of introduced and native ascidians in bivalve cultures in the Ebro Delta (NE Iberian Peninsula)
Ascidians are important both as invasive species and as a fouling group in artificial marine habitats, causing negative impacts in aquaculture settings and the surrounding environment. The Ebro Delta is one of the major ... -
Seasonal-and dose-dependent effects of recombinant gonadotropins on sperm production and quality in the flatfish Solea senegalensis
Consecutive treatments with recombinant follicle-stimulating and luteinizing hormones (rFsh and rLh, respectively) stimulate spermatogenesis and potentiate sperm production in pubescent specimens of the oligospermic ... -
Selection of flowering plants to enhance the biological control of Tuta absoluta using parasitoids
The tomato moth Tuta absoluta is an important pest of tomato crops. To enhance biological control services, our study aims to ascertain the effect of potential insectary plants (Achillea millefolium, Calendula officinalis, ... -
Self-assembled monolayer-based immunoassays for okadaic acid detection in seawater as monitoring tools
Rapid and cost-effective methods to monitor the presence of diarrhetic shellfish poisoning (DSP) toxins in seawater samples in an easy and reliable manner are required to protect human health and avoid economic losses to ... -
Sequencing of Tuta absoluta genome to develop SNP genotyping assays for species identification
Tuta absoluta is one of the most devastating pests of fresh market and processing tomatoes. Native to South America, its detection was confined to that continent until 2006 when it was identified in Spain. It has now spread ... -
Sexually dimorphic tibia shape is linked to natural osteoarthritis in STR/Ort mice
Objectives:Human osteoarthritis (OA) is detected only at late stages. Male STR/Ort mice develop knee OAspontaneously with known longitudinal trajectory, offering scope to identify OA predisposing factors. Weexploit the ... -
Short- and long-term effects on growth and expression patterns in response to incubation temperatures in Senegalese sole
In this study, the short- and long-term effects of embryo incubation temperatures (16, 18 and 20 °C) on development and growth of the flatfish Senegalese sole (Solea senegalensis) was determined by investigating the ... -
Should animal welfare regulations be more restrictive? A case study in eight European Union Countries
Increasingly, intensive livestock production systems have increased societal concern regarding the current animal welfare standards. We investigated whether individuals in their roles as consumers and citizens believe ... -
Skeletal muscle metabolomics and blood biochemistry analysis reveal metabolic changes associated with dietary amino acid supplementation in dairy calves
The efects of diferent amino acid (AA) supplementations of milk protein-based milk replacers in pre-ruminant calves from 3 days to 7 weeks of age were studied. Animals were divided into 4 groups: Ctrl) Control group fed ... -
Skeletogenesis in the Persian sturgeon Acipenser persicus and its correlation with gene expression of vitamin K‐dependent proteins during larval development
The present study describes morphological development of the skeleton in the Persian sturgeon Acipenser persicus and discusses the hypothesis that expression of genes encoding vitamin K‐dependent proteins (VKDP) might be ... -
Skin mucus metabolites in response to physiological challenges: A valuable non-invasive method to study teleost marine species
Knowledge concerning the health and welfare of fish is important to conserve species diversity. Fish mucosal surfaces, and particularly the skin, are of utmost importance to protect the integrity and homeostasis of the ... -
Soil microclimate changes affect soil fungal communities in a Mediterranean pine forest
Soil microclimate is a potentially important regulator of the composition of plant‐associated fungal communities in climates with significant drought periods. Here, we investigated the spatio‐temporal dynamics of soil ... -
Soil porosity changes in orchards with subsurface irrigation: quantification and interpretation
In order to assess the irrigation efficiency under water-limiting conditions, four different treatments of subsurface irrigation of peach trees in a semi-arid Mediterranean climate near Lleida (NE Iberian Peninsula) ... -
Solea senegalensis skeletal ossification and gene expression patterns during metamorphosis: New clues on the onset of skeletal deformities during larval to juvenile transition
Farmed Senegalese sole (Solea senegalensis) still show a high incidence of vertebral anomalies that limit its intensive production and hamper its economic profitability. A great effort towards understanding how fish species ... -
Sorption of carbon dioxide by chickpeas packaged in modified atmospheres
Modified atmospheres (MAs) with high CO2 concentrations are used for packaging several commodities with different purposes, including as an alternative method for pest control. When used in gas-tight flexible packages, ...
