Rahnella spp. are commonly isolated from onion (Allium cepa) bulbs and are weakly pathogenic
(Journal article; Peer reviewed, 2019)Aims Bacterial decays of onion bulbs have serious economic consequences for growers, but the aetiologies of these diseases are often unclear. We aimed to determine the role of Rahnella, which we commonly isolated from bulbs ... -
Raman micro-spectroscopy of two types of acetylated Norway spruce wood at controlled relative humidity
(Peer reviewed; Journal article, 2022-09-06)Water is a key element for wood performance, as water molecules interact with the wood structure and affect important material characteristics such as mechanical properties and durability. Understanding wood-water interactions ... -
Range expansion of the small spruce bark beetle Ips amitinus: a newcomer in northern Europe
(Journal article; Peer reviewed, 2019)1 Ips amitinus arrived in Northern Europe at the beginning of 1900s, although its recent expansions to the northernmost conifers have been rapid. 2 Analyses of recent records, MaxEnt models and regional population size ... -
Range-wide whole-genome resequencing of the brown bear reveals drivers of intraspecies divergence
(Peer reviewed; Journal article, 2023-02-06)Population-genomic studies can shed new light on the effect of past demographic processes on contemporary population structure. We reassessed phylogeographical patterns of a classic model species of postglacial recolonisation, ... -
Rangeland Grazing Strategies to Lower the Dependency on Imported Concentrates in Norwegian Sheep Meat Production
(Peer reviewed; Journal article, 2020-07-01)Norway has vast rangeland resources (292,361 km2) with an estimated carrying capacity of nearly four million sheep and lambs, twice the current number. However, the intensive production system currently applied has led to ... -
Rapid and accurate determination of protein content in North Atlantic seaweed by NIR and FTIR spectroscopies
(Peer reviewed; Journal article, 2022-10-21)Seaweed is considered a potentially sustainable source of protein for human consumption, and rapid, accurate methods for determining seaweed protein contents are needed. Seaweeds contain substances which interfere with ... -
Rapid photosynthetic recovery of a snow-covered feather moss and Peltigera lichen during sub-Arctic midwinter warming
(Journal article; Peer reviewed, 2013-03-06)Background: Arctic lichens and mosses are covered by snow for more than half the year and are generally considered as being dormant for most of this period. However, enhanced frequency of winter warming events due to climate ... -
A re-analysis of NH4+ sorption on biochar: Have expectations been too high?
(Peer reviewed; Journal article, 2022-04-22)Sorption of nutrients such as NH4+ is often quoted as a critical property of biochar, explaining its value as a soil amendment and a filter material. However, published values for NH4+ sorption to biochar vary by more than ... -
Re-evaluation of the genus Englerodendron (Leguminosae–Detarioideae), including Isomacrolobium and Pseudomacrolobium
(Peer reviewed; Journal article, 2019-10-11)On the basis of a new phylogeny of the Detarioideae, with a particular focus on Englerodendron Harms, Anthonotha P.Beauv. and related genera, the possible options for delimiting monophyletic genera are discussed. As a ... -

Rebaling of silage and haylage and its effects on forage microbial and chemical composition—A pilot study
(Peer reviewed; Journal article, 2020-04-22)Use of big bale silage and haylage can be difficult on farms where daily forage consumption is comparatively low as speed of deterioration of forage after bale opening may be faster than feed‐out rate. Production of smaller ... -
Recent strengthening of snow and ice albedo feedback driven by Antarctic sea-ice loss
(Peer reviewed; Journal article, 2021-10-28)The decline of the Arctic cryosphere during recent decades has lowered the region’s surface albedo, reducing its ability to reflect solar radiation back to space. It is not clear what role the Antarctic cryosphere plays ... -
Recent warming across the North Atlantic region may be contributing to an expansion in barley cultivation
(Journal article; Peer reviewed, 2017-12)Although grass dominates most agricultural systems in the North Atlantic region (NAR), spring barley is the most important cereal and is used for animal feed and food and drink products. Recent changes in climate have ... -
