Nutraceutical characterization of anthocyanin-rich fruits produced by «Sun Black» tomato line
(Peer reviewed; Journal article, 2019-08-28)Tomato (Solanum lycopersicum L.) is one of the most cultivated vegetable in the world and it represents a large source of bioactive compounds, including carotenoids and polyphenols (phenolic acids and flavonoids). However, ... -
Nutrient and chemical contaminant levels in five marine fish species from Angola—The EAF-Nansen programme
(Journal article; Peer reviewed, 2020)Fish is a rich source of several important nutrients and an important part of the otherwise plant-dominated diet present in Angola. However, fish may also be a source of contaminants. The aim of this study was to analyse ... -
Nutrient Digestibility, Growth, Mucosal Barrier Status, and Activity of Leucocytes From Head Kidney of Atlantic Salmon Fed Marine- or Plant-Derived Protein and Lipid Sources
(Journal article; Peer reviewed, 2021-02-19)Nutrient digestibility, growth, and mucosal barrier status of fish skin, gills, and distal intestine were studied in Atlantic salmon fed feeds based on marine or plant-derived ingredients. The barrier status was assessed ... -
Nutrient fuxes from an Arctic seabird colony to the adjacent coastal marine ecosystem
(Journal article; Peer reviewed, 2022)Seabirds are important vectors for nutrient transfer across ecosystem boundaries. In this seasonal study, we evaluate the impact of an Arctic colony (Alkhornet, Svalbard) of Black-legged Kittiwakes (Rissa tridactyla) and ... -
Nutrient pathways through the microbial food web: principles and predictability discussed, based on five different experiments
(Peer reviewed; Journal article, 2010-11-11)Although explanatory and predictive powers are 2 closely interconnected aspects of conceptual and mathematical models of complex systems, the two are not equivalent. The 2 aspects are discussed here for the microbial part ... -
Nutrient use by tropical ant communities varies among three extensive elevational gradients: A cross-continental comparison
(Journal article; Peer reviewed, 2023)Aim: Many studies demonstrate that climate limits invertebrates along tropical elevational gradients, but we have only a rudimentary understanding of the role of nutrient limitation and climatic seasonality. Here we examined ... -
