Field size as a determinant of common vole population density
Pest Management Science, EarlyView.Population densities of the common vole, an agricultural pest, increase nonlinearly with forage field size, especially in fields below 20 ha. Reducing the field size may help limit crop damage in farmland. Abstract BACKGROUND Environmental heterogeneity in agricultural landscapes is a key driver of biodiversity and ecological processes, yet its role in

Relationship between food quality and body size of common vole in different habitats
Pest Management Science, EarlyView.The body size of the common vole in crop fields (alfalfa, rape, cereals) is larger than in less‐cultivated habitats (forests, clearings, set‐aside) and is not related to food quality. Abstract BACKGROUND There is a close relationship between habitat, food and demographic parameters of common vole populations.

Strip loading in reinforced concrete: Mechanical modeling and experimental validation
Structural Concrete, EarlyView.Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

Hay Price Forecasts at the State Level [PDF]
Higher prices for major crops (e.g., corn, soybeans and wheat) have received considerable attention by analysts, researchers, and producers. A common perception is that acres can be readily bid away from other crops to quickly return to equilibrium price

SEQUENTIAL STOCHASTIC PRODUCTION DECISIONS FOR A PERENNIAL CROP: THE YIELD/QUALITY TRADEOFF FOR ALFALFA HAY [PDF]
The "optimal cutting schedule" for alfalfa hay is described as a function of the trade-off between rising yield and falling quality of alfalfa over time and the local market prices being offered for different qualities of hay during the harvest season ...
