The origin of the Legumes is a complex paleopolyploid phylogenomic tangle closely associated with the Cretaceous–Paleogene (K–Pg) mass extinction event
(Peer reviewed; Journal article, 2020-08-31)The consequences of the Cretaceous–Paleogene (K–Pg) boundary (KPB) mass extinction for the evolution of plant diversity remain poorly understood, even though evolutionary turnover of plant lineages at the KPB is central ... -
An Overview of Microbial Source Tracking Using Host-Specific Genetic Markers to Identify Origins of Fecal Contamination in Different Water Environments
(Peer reviewed; Journal article, 2022-06-04)Fecal contamination of water constitutes a serious health risk to humans and environmental ecosystems. This is mainly due to the fact that fecal material carries a variety of enteropathogens, which can enter and circulate ... -
Oxalate found in wood cell wall during incipient brown rot degradation
(Peer reviewed; Journal article, 2022-11-21)Brown rot fungi are a marvel and an enigma of Nature. They are capable of depolymerizing holocellulose within wood cell walls without significantly ineralizing lignin. The exact details behind this feat remain unknown, but ... -
Parallel Microbial Ecology of Pasteuria and Nematode Species in Scottish Soils
(Peer reviewed; Journal article, 2020-01-28)Pasteuria spp. are endospore forming bacteria which act as natural antagonists to many of the most economically significant plant parasitic nematodes (PPNs). Highly species-specific nematode suppression may be observed in ... -
A parametric analysis of eco-efficiency and its determinants: Evidence from Norwegian dairy farms
(Peer reviewed, 2023-07-25)This study aims to estimate eco-efficiency scores and identify determinants of Norwegian dairy farms using a parametric approach that accounts for methane emissions. The study incorporates an environmental output measure ... -
Parasitoids indicate major climate-induced shifts in arctic communities
(Peer reviewed; Journal article, 2020-09-11)Climatic impacts are especially pronounced in the Arctic, which as a region is warming twice as fast as the rest of the globe. Here, we investigate how mean climatic conditions and rates of climatic change impact parasitoid ... -
Pathogenicity, host specificity and genetic diversity in Norwegian isolates of Microdochium nivale and Microdochium majus
(Peer reviewed; Journal article, 2020-01-31)Microdochium majus and Microdochium nivale cause serious disease problems in grasses and cereal crops in the temperate regions. Both fungi can infect the plants during winter (causing pink snow mould) as well as under cool ... -
Patterns and roles of lignan and terpenoid accumulation in the reaction zone compartmentalizing pathogen-infected heartwood of Norway spruce
(Peer reviewed; Journal article, 2022-02-10)Tree defense against xylem pathogens involves both constitutive and induced phenylpropanoids and terpenoids. The induced defenses include compartmentalization of compromised wood with a reaction zone (RZ) characterized by ... -
Patterns of Carbon Sequestration in a Young Forest Ecosystem after Clear-Cutting
(Peer reviewed; Journal article, 2020-01-21)A large area of Estonian hemiboreal forest is recovering from clear-cut harvesting and changing carbon (C) balance of the stands. However, there is a lack of information about C- source/sink relationships during recovery ... -
Patterns of Microbiome Variation Among Infrapopulations of Permanent Bloodsucking Parasites
(Peer reviewed; Journal article, 2021-04-16)While interspecific variation in microbiome composition can often be readily explained by factors such as host species identity, there is still limited knowledge of how microbiomes vary at scales lower than the species ... -
Pedotransfer functions in Earth system science: challenges and perspectives
(Journal article; Peer reviewed, 2017-11-14)Soil, through its various functions, plays a vital role in the Earth’s ecosystems and provides multiple ecosystem services to humanity. Pedotransfer functions (PTFs) are simple to complex knowledge rules that relate available ... -
Perceived effects of climate policy on rural areas and agriculture: A rural-urban divide
(Peer reviewed; Journal article, 2023-04-03)Climate policies may have adverse geographically unequal socio-economic impacts that, if left unaddressed, may hamper their implementation. This paper examines factors explaining rural-urban perceptions of the effects of ... -
Performance and Phenotypic Stability of Norway Spruce Provenances, Families, and Clones Growing under Diverse Climatic Conditions in Four Nordic Countries
(Peer reviewed; Journal article, 2021-02-17)Genetic variation and phenotypic stability in Norway spruce were studied based on provenances, families, and clones planted in trials at 12 sites in four Nordic countries. The families were generated in a factorial cross ... -
Performance of Sweet Cherry Cultivars and Advanced Selections on Gisela 5 Rootstock in Young Orchards
(Peer reviewed; Journal article, 2023-01-30)Six sweet cherry cultivars and two advanced selections of Gisela 5 rootstock were tested in 2015–2021 at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. Fruit trees were planted at ... -
Performance of the Endemic Alpine Herb Primula scandinavica in a Changing European Mountain Landscape
(Journal article; Peer reviewed, 2015-08)This paper reports on the performance of the red-listed Primula scandinavica, endemic to Scandinavia. The study took place in Jotunheimen, Norway. We evaluated occurrence, density and sexual reproduction variables (number ... -
Performance of the Norwegian dairy farms: A dynamic stochastic approach
(Peer reviewed; Journal article, 2020-08-07)From a theoretical perspective, it is well stated that the farm's decision on the use of inputs depends on the farmer's ability to make an efficient decision over time. The existing literature in performance analysis of ... -
