Three experiments examined effects on growth, dry matter partitioning and nutrient uptake in potato plants grown in large pots under different combinations of adequate and deficient levels of nitrogen, phosphorus and ...

Studies were conducted over 3 years to evaluate the effect of maturity at harvest (Year 1 and 2), pea content (Year 2) and pea variety (Magnus versus Setchey, Year 3) on the nutritional quality of inter-cropped, spring-sown, ...

Reducing the number of flowering tillers that perennial ryegrass produces would improve the feeding value of herbage and could also be used to reduce pollen flow to wild ryegrass populations. Equivalent populations with ...

A two colour fluorescent assay and a kit are described that permit the determination of live and dead parasitic or non-parasitic worms, for example helminths. The assay permits screening for the effect of one or more agents ...

The LjSym4 mutation leads to Lotus japonicus plants that are defective in arbuscular mycorrhiza (AM) development. Two alleles of LjSym4 with different phenotypic strength are compared here. The development of AM was assessed ...

Despite a number of biochemical and lifestyle differences which should increase risk of oxidative damage to their mitochondrial DNA (mtDNA) and thus reduce expected lifespan, avian species often display longer lifespans ...

Snow environments can occupy over a third of land surface area, but little is known about the dynamics of snowpack bacteria. The effect of snowmelt on bacterial community structure and diversity of surface environments of ...

The temporal dynamics of appetite (weight of food consumed per day) were analysed for fish fed to satiation after a 1 or 2-week period of feed deprivation. Three species were compared: two omnivores (minnow, Phoxinus ...

Abundance of a population of three-spined stickleback, Gasterosteus aculeatus L., in a small backwater of Afon Rheidol in mid-Wales (UK) was estimated annually each October from 1972 to 1999 by mark-recapture. 2. The ...
