Animals may respond to habitat quality and habitat edges and these responses may affect their distribution between habitats. We studied the movement behaviour of a ground-dwelling generalist predator, the carabid beetle Pterostichus melanarius (Illiger). We performed a mark-recapture experiment in two adjacent habitats; a large plot with oilseed radish (Raphanus sativus) and a plot with rye (Se...

The effects of management of genetically modified herbicide-tolerant (GMHT) crops on adjacent field margins were assessed for 59 maize, 66 beet and 67 spring oilseed rape sites. Fields were split into halves, one being sown with a GMHT crop and the other with the equivalent conventional non-GMHT crop. Margin vegetation was recorded in three components of the field margins. Most differences were...

10 The dry and wet deposition of radionuclides released into the atmosphere can be 11 intercepted by vegetation in terrestrial ecosystems. The aim of this study was to quantify the 12 interception of wet deposited Cs and Sr by spring oilseed rape (Brassíca napus L.) and 13 spring wheat (Tríticum aestívum L.). The dependency of the intercepted fraction (f) on total 14 above ground plant biomass,...

Because it has a high demand for sulphur (S), oilseed rape is particularly sensitive to S limitation. However, the physiological effects of S limitation remain unclear, especially during the rosette stage. For this reason a study was conducted to determine the effects of mineral S limitation on nitrogen (N) and S uptake and remobilization during vegetative growth of oilseed rape at both the who...

Oilseed rape (Brassica napus L.), which has yellow flowers, is both an important oil crop and a traditional tourism resource in China, whereas the Orychophragmus violaceus, which has purple flowers, likely possesses a candidate gene or genes to alter the flower colour of oilseed rape. A previously established B. napus line has a particular pair of O. violaceus chromosomes (M4) and exhibits slig...

Biodiesel produces fewer pollutants than petroleum diesel, and is virtually free of sulfur. These properties make biodiesel an attractive candidate to facilitate compliance with the Clean Air Act Amendments of 1990 (CAAA). This fuel is ordinarily considered to be derived from oilseeds, but an essentially identical biodiesel can be made from microalgae. This technology is complementary to ongoin...

Insect pollinated mass flowering crops are becoming more widespread and there is a need to understand which insects are primarily responsible for the pollination of these crops so conservation measures can be appropriately targeted in the face of pollinator declines. This study used field surveys in conjunction with cage manipulations to identify the relative contributions of different pollinat...

Camelina sativa (L.) Crantz (camelina) is an oilseed producing plant in the family Brassicaceae (Cruciferae) originating from the Mediterranean to Central Asia [1]. Camelina meal (CM) is the by-product of camelina oil extraction and has a crude protein content similar to canola meal [2]. There is increasing interest in converting waste cooking oil and oil produced from oilseed crops, such as ca...

OBJECTIVES "Toy premiums", offered with McDonald's Happy Meals®, are a prominent form of food marketing directed at children. Two California jurisdictions recently implemented policies that only permit offering fast-food toy premiums with meals that meet certain nutritional criteria. The primary objective of the current study was to examine elements of this policy in a Canadian context and dete...

OBJECTIVE To assess whether a late evening meal would improve nitrogen balance in patients with cirrhosis of the liver. DESIGN Randomised crossover study of meal schedules comparing three meals a day with four or six meals a day, the four and six meal schedules both including a late evening meal (2300). SETTING Metabolic ward. PATIENTS Seven men and two women aged 34-66 with cirrhosis of ...
