The effects of UV radiation on the content of phenolic acid and flavonoid, stomatal conductance and taste in red lettuce 'Lollo Rosso'
(Master thesis, 2016-08-31)The use of supplementary light to improve the quality of red lettuce is common practice in today’s greenhouse production. Fluorescent lamps that emit Ultraviolet (UV) radiation have been shown to increase the synthesis of ... -
The effects on soil physical properties of long term soil tillage and soil compaction
(Master thesis, 2014-11-04)Soil degradation in crop production is becoming increasingly important because of the growing concern it poses on soil functions. Prominent among the degradation factors is soil compaction. It impairs soil productivity ... -
The environmental occurrence, fate, and behavior of airborne organic contaminants of emerging concern in Norwegian terrestrial ecosystems
(Master thesis, 2019)Airborne organic contaminants of emerging concern (AOCs) are a large assembly of organic compound groups. AOCs consist of legacy persistent organic pollutants (POPs) and new POP- like compounds. These compound groups are ... -
The expansion of red foxes (Vulpes vulpes) into alpine areas - Effects of human-induced subsidies along roads, and consequences for ground-nesting birds
(Master thesis, 2016-08-15)During the past century, the red fox (Vulpes vulpes) has gradually increased its presence in alpine habitats, threatening endangered species such as the arctic fox (Vulpes lagopus). Several factors have been suggested ... -
The exposure of terrestrial biota to naturally occuring radiation and stable elements : case Orrefjell, a risk assessment
(Master thesis, 2018)Naturally occurring radioactive materials (NORM) can be found all over the world. Investigations of possible effects on humans and the environment have mostly focused on exploited sites like mines and their vicinity, while ... -
The fate of nitrogen in an Acrisol in Zambia under different management practices
(Master thesis, 2019)A 10-day 15N tracer experiment, using 15N-NO3 and 15N-NH4, was conducted on an Acrisol in Mkushi, Zambia, in a rain-fed maize field. The addition of the 15N label, as either 15N-NO3 or 15N-NH4, was equivalent to 0.1g/m2 ... -
The fffects of changes in livestock grazing and agricultural land use on an endangered orchid, Herminium monorchis, in Norway : a correlative and experimental approach
(Master thesis, 2016-08-31)Changes in agricultural practices and land use, with abandonment of low-intensity grazing and the transformation of semi-natural meadows into cultivated agricultural areas, have shown negative impacts on several plant ... -
The forest Carbon Certification Project in Iceland : a case study
(Master thesis, 2011-11-11)This study is a part of a bigger project aimed to develop a certification system for carbon stock changes due to afforestation in Iceland. This is interesting because carbon credits created by removals of CO2 from the ... -
The fungal factor : male spider mites prefer fungally killed females to healthy live ones
(Master thesis, 2016-07-27)The two-spotted spider mite, Tetranychus urticae, is a serious pest in a wide variety of crops worldwide, and can negatively affect the production of strawberries. Males of T. urticae approach and guard quiescent deutonymph ... -
