Full-skala nasjonal arealrepresentativ overvåking av semi-naturlig eng (ASO). Erfaring fra 1. års gjennomføring, og revidering av metoder og feltinstruks
(NIBIO-rapport;7(194) 2021, Research report, 2021-12)Semi-naturlig eng er en truet naturtype i Norge og er i sterk tilbakegang. ASO (arealrepresentativ overvåking av semi-naturlig eng) metoden er utviklet for å kunne gi arealrepresentative tall for denne tilbakegangen og for ... -
Fulldyrka areal og kornarealer på Østlandet
(Rapport fra skog og landskap;, Research report, 2014)Kornarealet har gått kraftig tilbake siden år 2000. Størst nedgang i kornareal finner vi i flatbygdene på Østlandet. Nær halvparten av kornarealet som har gått ut av produksjon her har blitt lagt om til gras. Den største ... -
Fulldyrka areal og små jordstykker
(Fakta fra Skog og landskap;10/2013, Others, 2013)Litt over halvparten av arealet med gras ligger på jordstykker som er under 20 dekar, og nesten en fjerdedel av kornarealet ligger på jordstykker under 20 dekar. Å slå sammen jordstykker for å redusere andelen areal på små ... -
Fulldyrka jord og dyrkbar jord - en landsoversikt
(Fakta fra Skog og landskap;2014-14, Journal article, 2014)Ved utgangen av 2013 er 8 734 km2 kartlagt som fulldyrka jord og 13 037 km2 kartlagt som dyrkbar jord i Norge. Dette utgjør henholdsvis 2,9 og 4,3 prosent av landarealet. En fullstendig oversikt er tilgjengelig på fylkes- ... -
Fumonisins in African Countries
(Peer reviewed; Journal article, 2022-06-19)Maize and other cereals are the commodities most contaminated with fumonisins. The maize acreage is increasing in Africa, and the maize harvest provides important foods for humans and feeds for domestic animals throughout ... -
Functional characterization of Pseudoidium neolycopersici photolyase reveals mechanisms behind the efficacy of nighttime UV on powdery mildew suppression
(Peer reviewed; Journal article, 2020-05-29)Powdery mildews can be controlled by brief exposure to ultraviolet (UV) radiation with devastating effect on their developmental stages including conidia germination. The treatment effect can be impaired by subsequent ... -
Functional diversity and invasive species influence soil fertility in experimental grasslands
(Peer reviewed; Journal article, 2020-01-01)Ecosystem properties can be positively affected by plant functional diversity and compromised by invasive alien plants. We performed a community assembly study in mesocosms manipulating different functional diversity levels ... -
Functional genomics of wood degradation - a project summary
(Chapter, 2011)Modified wood can provide protection against a range of wood deteriorating organisms. Several hypotheses have been put forward for the mode of action against wood decaying fungi, including inhibition of action of specific ... -
Functional growth analysis of ‘Sonata’ strawberry plants grown under controlled temperature and daylength conditions
(Journal article; Peer reviewed, 2016-08-17)In order to investigate the relationship between environmental conditions and vegetative growth and reproductive development in the strawberry, freshly rooted runner plants of the cultivar ‘Sonata’ were grown in a phytotron ... -
Functional phenomics for improved climate resilience in Nordic agriculture
(Peer reviewed; Journal article, 2022-09-03)The five Nordic countries span the most northern region for field cultivation in the world. This presents challenges per se, with short growing seasons, long days, and a need for frost tolerance. Climate change has ... -
Functionality of Embryo Sacs in Pear Cultivars ‘Ingeborg’ and ‘Celina’ as Related to Fruit Set under Nordic Climate
(Peer reviewed; Journal article, 2020-12-05)Since the European pear (Pyrus communis L.) is a self-incompatible fruit species, synchrony and compatibility between female parts of the mother plant and male gametes from the pollen donor must be fulfilled. Besides ... -
Fundamental resource specialization of herbivorous butterflies decreases towards lower latitudes
(Peer reviewed; Journal article, 2021-08-17)Aim It is generally assumed that the degree of resource specialization in herbivorous insects increases towards lower latitudes. However, latitudinal patterns in herbivore diet breadth at large spatial scales remain poorly ... -
Fungal associates of the tree-killing bark beetle, Ips typographus, vary in virulence, ability to degrade conifer phenolics and influence bark beetle tunneling behavior
(Journal article; Peer reviewed, 2018-07-20)The bark beetle Ips typographus carries numerous fungi that could be assisting the beetle in colonizing live Norway spruce (Picea abies) trees. Phenolic defenses in spruce phloem are degraded by the beetle's major tree-killing ... -
Fungal attack on archaeological wooden artefacts in the Arctic—implications in a changing climate
(Peer reviewed; Journal article, 2020-09-03)Climate change is expected to accelerate the microbial degradation of the many extraordinary well-preserved organic archaeological deposits found in the Arctic. This could potentially lead to a major loss of wooden artefacts ... -
