Denne rapporten gir en kortfattet oversikt over publiserte arbeider vedrørende studier av genetisk variasjon i norske skogtrær. Her er bare tatt med originale arbeider som karakteriserer genetisk variasjon og genetiske prosesser som påvirker variasjonen. Arbeider som kun beskriver metodikk og teknikker er utelatt.

The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the economic importance, few genetic resources for downstream applications, such as linkage mapping, parentage analysis, marker-assisted selection (MAS), quantitative trait loci (QTL) analysis, and assessing adaptive genetic diversity are currently available for the species. Here, we identify both genome- and transcriptome-derived microsatellites loci from C. lumpus to facilitate such applications. Across 2,346 genomic contigs, we detected a total of 3,067 microsatellite loci, of which 723 were the most suitable ones for primer design. From 116,555 transcriptomic unigenes, we identified a total of 231,556 microsatellite loci, which may indicate a high coverage of the available STRs. Out of these, primer pairs could only be designed for 6,203 loci. Dinucleotide repeats accounted for 89 percent and 52 percent of the genome- and transcriptome-derived microsatellites, respectively. The genetic composition of the dominant repeat motif types showed differences from other investigated fish species. In the genome-derived microsatellites AC/GT (67.8 percent), followed by AG/CT (15.1 percent) and AT/AT (5.6 percent) were the major motifs. Transcriptome-derived microsatellites showed also most dominantly the AC/GT repeat motif (33 percent), followed by A/T (26.6 percent) and AG/CT (11 percent). Functional annotation of microsatellite-containing transcriptomic sequences showed that the majority of the expressed sequence tags encode proteins involved in cellular and metabolic processes, binding activity and catalytic reactions. Importantly, STRs linked to genes involved in immune system process, growth, locomotion and reproduction were discovered in the present study. The extensive genomic marker information reported here will facilitate molecular ecology studies, conservation initiatives and will benefit many aspects of the breeding programmes of C. lumpus.

The SusCatt project investigates alternative systems to improve sustainability in European cattle production, taking different approaches in Norway, Sweden, Germany, Poland, UK and Italy – all making greater use of pasture and forage, reducing damaging or external inputs. Rather than us deciding on how we tell everybody about findings, one project task is to ask potential audiences about their sources of information – how they gain knowledge? Ideally, this will offer guidance on an effective dissemination strategy. Project messages are relevant to multiple sectors: farmers, extension workers, consumers and policy makers. Attempts were made to survey these multiple stakeholders. We collected 236 opinions and found considerable variation, not only between groups but also between the same sectors in different countries. The most popular and highest-ranking sources overall were traditional press formats of newspapers and magazines. On the other hand, accessing information from social media was very polarised; almost non-existent for German and Polish stakeholders but widely used by UK farmers (possibly skewed by the dominance of face-to-face rather than on-line data collection). Findings suggest that each message from research projects needs a customized approach in dissemination, depending on the target audience and their regular habits of sourcing information

Tålmodighet er en dyd. Men det kan oppleves risikofylt å vente tålmodig på at ei langvarig eng skal finne balansen som kreves for å oppnå god avling og kvalitet. Likevel er det nettopp det forsker i NIBIO, Ievina Sturite, ber oss vurdere. Resultatet kan vise seg lønnsomt , både for økonomi og miljø.
