The influence of nitrate pollution on elemental and isotopic composition of aquatic and semi-aquatic bryophytes
(Elsevier, 2023-09-09)
Bryophytes can play an important role in key ecosystem processes and represent potential candidates as bioindicators for environmental monitoring programmes. Nitrate (NO3−) pollution poses a growing ...
The feasibility of using gas mixture to stun seabream (Sparus aurata) before slaughtering in aquaculture production
(Elsevier, 2021-07-10)
Current European Union regulation explicitly states that farmed fish should be spared any avoidable pain, distress or suffering at the time of slaughter. It has been shown that fish suffer when they are ...
Role of mycorrhizas and root exudates in plant uptake of soil nutrients (calcium, iron, magnesium, and potassium): has the puzzle been completely solved?
(Wiley, 2023-03-14)
Anthropogenic global change is driving an increase in the frequency and intensity of drought and flood events, along with associated imbalances and limitation of several soil nutrients. In the context ...
Development of a novel metric for evaluating diatom assemblages in rivers using DNA metabarcoding
(Elsevier, 2020-08-10)
Fundamental differences in the nature of diatom assemblage composition data generated using light microscopy and molecular barcoding create problems when applying current paradigms and metrics developed ...
Environmental life cycle assessment of producing willow, alfalfa and straw from spring barley as feedstocks for bioenergy or biorefinery systems
(Elsevier, 2016-10-17)
The aim of this study is to assess the potential environmental impacts of producing maize, grass-clover, ryegrass, and straw from winter wheat as biomass feedstocks for biorefinery. The Life Cycle ...
Effects of copper and zinc sources and inclusion levels of copper on weanling pig performance and intestinal microbiota
(Oxford University Press, 2020-04-11)
A 42 day experiment was conducted to evaluate the effect of Cu and Zn source and Cu level on pig performance, mineral status, bacterial modulation, and the presence of antimicrobial resistant genes in ...
Meta‐analysis approach to the effects of live prey on the growth of Octopus vulgaris paralarvae under culture conditions
(Wiley, 2016-02-14)
The common octopus (Octopus vulgaris, Cuvier 1797) is a promising species for aquaculture diversification, but the massive mortality during the first life stage is the main bottleneck for its commercial ...
The use of recovered struvite and ammonium nitrate in fertigation in a horticultural rotation: agronomic and microbiological assessment
(Taylor & Francis, 2022-12-12)
Phosphorus and nitrogen recovery from wastewater as struvite and ammonium nitrate (AN) may be viable alternative fertilizers to boost circularity in horticulture. A 2-year fertigated crop rotation in ...
Pharmaceuticals and endocrine disruptors in raw and cooked seafood from European market: Concentrations and human exposure levels
(Elsevier, 2018-08-30)
Pharmaceuticals (PhACs) and endocrine disrupting compounds (EDCs) are chemicals of emerging concern that can accumulate in seafood sold in markets. These compounds may represent a risk to consumers ...
Biosecurity assessment of Argentinian pig farms
(Elsevier, 2019-02-27)
