Farmers' Beliefs About Climate Action: Evidence From an Information Experiment

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Farmers' adoption of climate change mitigation practices is crucial for reducing greenhouse gas (GHG) emissions from food production. One major source of these emissions is chemical fertilizer application. Introducing clover into grassland can mitigate emissions by reducing the need for chemical fertilizers.

Nitrate leaching in grazed grasslands of different composition and age [PDF]

open access: yes, 2002
In a field experiment at Research Centre Foulum a suction cup technique was used to investigate nitrate leaching from grassland depending on composition (grass-clover or perennial ryegrass), management (grazing or cutting) and age of the swards.

Is the endophyte‐based plant protection against aphids mediated by changes in the insect microbiome?

open access: yesInsect Science, EarlyView.
We showed that the fungal endophyte Epichloë strain AR37 increased the plant resistance against aphids via the production of indole diterpene alkaloids. The reduction in aphid performance was not associated with changes in abundance/composition/diversity of the insect's bacterial microbiota, but additional endophyte effects on this microbiota cannot be

Selection of perennial and Italian ryegrass plants resistant to ryegrass mosaic virus

open access: yesAnnals of Applied Biology, 1976
SUMMARYPerennial ryegrass plants collected from fields and Italian ryegrass plants grown from seed were selected for resistance to infection by ryegrass mosaic virus (RMV) by repeated manual inoculation. Two of 108 perennial ryegrass plants and one of 150 Italian ryegrass plants were symptomless after seven and nine inoculations respectively.

Biphasic Effects on Allergen‐Specific Type 2 Memory B Cells Over 18 Months Sublingual Immunotherapy for House Dust Mite Allergy

open access: yesAllergy, EarlyView.
Rapid clinical relief of allergy symptoms during 18 months of sublingual immunotherapy (SLIT) for house dust mite (HDM) is associated with increased serum IgE, IgG2, and IgG4 to Der p 1 and Der p 2. Der p 1 and Der p 2 specific Type 2 memory B cells are expanded at 4 months and 12 months of SLIT, with increased expression of CD29 and IgG4.

Effects of cutting frequency on plant production, N-uptake and N2 fixation in harvested and below-harvest plant biomass of grass clover [PDF]

open access: yes, 2006
Nitrogen (N) accumulating in stubble, stolons and roots is an important component in N balances in perennial ryegrass-white clover swards, and the effects of cutting frequency on the biomass of above- and below-harvest height were studied during two ...

Changes in the microbiome and metabolome in captive red kangaroos (Osphranter rufus) affected by macropod progressive periodontal disease

open access: yesAustralian Veterinary Journal, EarlyView.
Macropod progressive periodontal disease (MPPD) is a severe oral condition frequently observed in captive macropods, particularly red kangaroos (Osphranter rufus), yet its underlying biological features remain poorly understood. In this exploratory descriptive study, we investigated oral and fecal microbiomes and metabolomic profiles in captive red ...
