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

Effect of Replacing Alfalfa Hay with Alfalfa Silage in High Performance Dairy Cattle Diets
پژوهشهای علوم دامی ایران, 2014 Four-handed fifty lactating Holstein cows with mean body weight of, 597± 40 and 50±20 and days in milk body Condi from sure of 3.1±0.4 were blocked by parity and randomly assigned to 3 treatments. Each treatment had 3 pens and each pen had 50 cows.

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.

Biological Control of Alfalfa Blotch Leafminer (Diptera: Agromyzidae) in Ontario: Status and Ecology of Parasitoids (Hymenoptera: Braconidae, Eulophidae) 20 Years After Introduction [PDF]
, 2018 Two European parasitoid species were released in Ontario during the late 1970\u27s to control the alfalfa blotch leafminer, Agromyza frontella (Rondani) (Diptera: Agromyzidae). One of these, Dacnusa dryas (Nixon) (Hymenoptera: Braconidae), rapidly became

Strip loading in steel fiber reinforced concrete: Experimental and theoretical investigation
Structural Concrete, EarlyView.Abstract Fiber reinforced concrete is becoming increasingly popular in engineering practice due to its high robustness, post‐cracking behavior, and crack control. For strip loading, as common, for example, in longitudinal joints of tunnel lining segments, the use of fiber reinforced concrete has the potential to reduce conventional reinforcement ...

TAXON, EarlyView.Abstract Freshwater Peridinium willei (Peridiniaceae) is globally distributed, but reports linking its morphologies with DNA sequence data remain scarce. The taxonomy of the species, and its infraspecific taxa, remain ambiguous due to the lack of DNA sequence data for the original and type material.

Short communication. Nitrogen content of residual alfalfa taproots under irrigation
Spanish Journal of Agricultural Research, 2013 The decomposition of alfalfa (Medicago sativa L.) residues can provide significant amounts of N to subsequent crops, but most of the data on this subject has been obtained from 1-2 year old alfalfa stands. The objective of this study was to determine the
