Despite the relatively long history of captive breeding, Arctic charr still exhibits a generally low, but highly variable reproductive performance in aquaculture. A recent publication exposed potential paternal factors influencing outcome broodstock from Swedish breeding program. Interestingly, factor appeared to be more closely connected embryo survival than fertilisation rates. This lead spec...

We evaluated nutrient uptake efficiency and subsequent leaching fractions for western white pine (Pinus monticola Dougl. ex D. Don) seedlings grown with exponentially increasing or conventional (constant) fertilization in a greenhouse. Conventional fertilization was associated with higher leachate electrical conductivity and greater nutrient losses, which were more pronounced for the more mobil...

For many years, the management of male-factor infertility has been empirical rather than evidence-based. In current clinical practice, assisted reproductive techniques are the most successful methods of alleviating male-factor infertility. To date, it remains unclear what adjuvant actions can be taken to improve the outcome of assisted reproductive techniques for male-factor infertility. Eviden...

Traditionally, annual colonising species are expected to have high rates of self-fertilisation, although recent theoretical and empirical studies have shown that cross-fertilisation can be selected for under heterogeneous pollination environments. Solanum rostratum is a self-compatible annual herb that colonises disturbed habitats. Despite the lack of physiological mechanisms to prevent self-fe...

The valorisation of vegetal waste as a source crop nutrients constitutes circular strategy to improve the sustainability intensive horticultural production systems. main goal this study was evaluate effects organic amendments derived from residues on yield and quality tomato. following fertilisation treatments were carried out: fresh (4 kg m?1), compost (3 vermicompost at two different doses 9 ...

27 Based on lipid analyses, 16S rRNA/rRNA gene single strand conformation polymorphism 28 fingerprints and methane flux measurements, influences of the fertilisation regime on 29 abundance and diversity of archaeal communities were investigated in soil samples from the 30 long-term (103 years) field trial in Bad Lauchstädt, Germany. The investigated plots followed 31 a gradient of increasing fe...

Lipids and essential fatty acids, particularly the highly unsaturated fatty acids, 20:5n-3 (eicosapentaenoic acid; EPA), 22:6n-3 (docosahexaenoic acid; DHA) and 20:4n-6 (arachidonic acid, AA) have been shown to be crucial determinants of marine fish reproduction directly affecting fecundity, egg quality, hatching success, larval malformation and pigmentation. In Atlantic cod (Gadus morhua L.) c...

Studia Forestalia Suecica 202. 15 pp. ISSN 0039-3150. ISBN 91-576-5399-2. Effects of fertilisation treatments (amounts and composition) on needle concentrations of micronutrients (boron, copper, iron, manganese and zinc), were studied in a long...
