Abstract When I was 12, my family told me a story about their community falling apart and coming together, a time when someone tried putting a nuclear facility in their (our?) hometown. Since we moved when I was too young to remember, the story had little significance until I embarked on a “hometown” ethnographic journey for my dissertation.

Seed lipid profiles from three ryegrass cultivars infected with AR501 show distinct changes in the medium‐chain diacylglycerols, triacylglycerols and sphingolipids. The differential peal LN745.5052_5.78 can be identified as PG 16:0_18:2 with the supporting ms2 fragmentation spectrum. Abstract Background Forage perennial ryegrass (Lolium perenne L.) has

Nitrogen Fertilization Temporarily Enhances Phosphatase Activity in a High‐P Loamy Sand
ABSTRACT Background Efficient plant utilization of soil phosphorus (P) is essential to reduce dependence on mineral P fertilizers in intensive agriculture. Input of mineral nitrogen (N) fertilizers and its chemical form may influence the activity of P mineralizing enzymes, but how this interaction operates under field conditions in a soil with high P ...

ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

ABSTRACT The main aim of the study was to assess the toxicity of ash generated in household furnaces through the combustion of materials most commonly burned in individual households. The toxicity tests were conducted using plant bioassays with cress (Lepidium sativum), mustard (Sinapis) and sorghum (Sorghum) seeds.
