Abstract
We present the complete genome sequence of Luteibacter rhizovicinus type strain LJ96T, a yellow-pigmented gammaproteobacterium isolated from the rhizosphere of barley (Hordeum vulgare) Johansen et al. (2005) , a species with numerous potential applications. The genome sequence was deposited to NCBI GenBank with the accession number CP017480.
Abstract
The genus Microbacterium contains bacteria that are ubiquitously distributed in various environments and includes plant-associated bacteria that are able to colonize tissue of agricultural crop plants. Here, we report the 3,508,491 bp complete genome sequence of Microbacterium sp. strain BH-3-3-3, isolated from conventionally grown lettuce (Lactuca sativa) from a field in Vestfold, Norway. The nucleotide sequence of this genome was deposited into NCBI GenBank under the accession CP017674.

Abstract
REDD+ aims to save and protect tropical forests, thus playing a major role in combating climate change and protecting biological diversity. However, many tropical countries lack the necessary forest monitoring method required for REDD+ funding, such as remote sensing with radar satellites and nation-wide forest inventories.
Abstract
Sustainable utilization of forest resources and the manufacture of high-quality wood products is a key element of the green shift. This transition can be accelerated by ensuring an increased and prolonged use of wood in buildings. But it’s important to get it right.

Industrialised chicken production is far from organic agriculture prinicples. Still of interest is a more sustainable utilisation of by-products, e.g. hydrolysation of feathers for proteins, or extraction of food grade oil from chicken bones. Such approaches were studied in the bioeconomy-project "CYCLE" (2013-2017).
Abstract
During processing (packaging) of vegetables and potatoes, large proportions are sorted out due to minor damage or deviations from strict visual standards. Out-sorted products are poorly paid, and have a short shelf-life. Processing to increase the payment and shelf-life may support a more sustainable utilisation of these by-products. Conserving as silage is one option, which was studied in the bioeconomy-project "CYCLE" (2013-2017). Other approaches are also discussed.

The temperate grasses in the subfamily Pooideae (Poaceae) has a limited distribution range The species are mainly distributed to the Northern Temperate regions and are known to be adapted to the strong seasonality this region possess. To be able to grow in such conditions, the plants have to edapt to the shift between the mild but short growing seasons and the harsh, long winters. In this study, I ask if the distribution of the subfamily is linked to the species growth rate traits. To be able to reproduce before winter returns in Northern temperate regions, it is an advantage to grow fast. The fundamental process of plant growth can be quantified using various growth rate traits, such as Relative Growth Rate (RGR), Standardised Growth Rate (SGR) and Allometric Slope. In order to analyse the evolutionary history of growth rates within Pooideae, a growth experiment were done. Here, traits related to growth were measured. Chloroplast sequences were retrieved from all the 64 populations of 55 species included in the experiment. The acquired datasets consisting of values of growth rate traits connected to chloroplast sequences were used in joint phylogenetic analyses with Ancestral State Reconstruction (ASR). Pooideae species in the Northern temperate lineages allocate more biomass to the shoots than to the roots. The results suggests that the most recent common ancestor (MRCA) of the monophyletic group core Pooideae made a switch in growth rate and Allometric Slope around 34 Ma, during a global cooling event.

The regular movement of animals between summer and winter ranges, termed seasonal migration, is a common phenomenon among ungulates at northern latitudes. The most prominent hypothesis to explain seasonal migration is the forage maturation hypothesis; it predicts that large herbivores will preferentially follow phenological (or green-up) gradients in order to access the highest possible forage quality with sufficient quantity. Surprisingly few studies provide empirical testing of the forage maturation hypothesis, and a question not often addressed is which landscape variables underlie the phenological gradient that makes migration a beneficial strategy. I tested the forage maturation hypothesis using the normalized difference vegetation index (NDVI), an index of plant phenology, and feces analyses as measures of forage quality and linked it with space use data from partially migratory red deer (Cervus elaphus) in Norway. Specifically, I investigated whether migratory individuals had access to higher quality forage than stationary, and the role of landscape variables for access to high quality forage. Generalized linear mixed models were used to analyze different measures of forage quality as responses to a set of covariates, including landscape variables. I found evidence that migratory red deer gain access to more high quality forage than stationary red deer, consistent with the forage maturation hypothesis. I found a positive effect of elevation on access to high quality forage for migratory individuals, and a diverse effect of other landscape characteristics, such as aspect and home range size. There was a positive effect of distance to fjord on accessed forage quality. This study sheds light on the relationship between the landscape an ungulate inhabit and the possibilities and limitations to access high quality forage within this landscape. Considering future climate change, and consequent changes in phenological gradients, it is important to understand the mechanisms causing the phenological gradients that migratory ungulates benefit from. Given the high diversity of impact by different variables found in this study, the effect of climate change may differ for populations across ecosystems.
