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 ... -
Partikler i drensvann
(Bioforsk rapport;1(93) 2006, Research report, 2006-06-06)Tilskudd til endret jordarbeiding blir gjerne prioritert til arealer med høy erosjonsrisiko. Men også drensvann fra flate arealer kan være tydelig påvirket av partikler i avrenningsepiosder. Erosjon på flate arealer er ... -
Partikler i drensvann. En litteraturundersøkelse
(Bioforsk rapport;2(4) 2007, Research report, 2007-07-12)Denne rapporten er en oppsummering av kunnskapstatus knyttet til partikkeltransport i drensvann og omhandler norske undersøkelser og litteratur fra de land som har sammenlignbare jord- og klimaforhold. Det er gjennomført ... -

Pathogenicity of some Ips typographus-associated blue-stain fungi to Norway spruce
(Meddelelser fra Norsk institutt for skogforskning;40.14, Research report, 1988-10)To test the pathogenicity of Ips typographus-associated fungi to Norway spruce, trees were inoculated with four species, Ophiostoma polonicum, O. bicolor, O. penicillltum and Graphium sp. Trees inoculated with the three ... -
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 ... -
På gjensyn! Norske villblomster takker for seg
(NIBIO POP;4(31) 2018, Journal article, 2018-12)Blomster bruker insekter for reproduksjon og frøsetting, samtidig som insekter bruker blomster som næringskilde for pollen og nektar. Tap av blomsterrike vegetasjonstyper som beiter og villenger, er blant de største truslene ... -
