The relationship between biodiversity and ecosystem function has received a great deal of attention in ecological research and recent results, from re-analyses, suggest that ecosystem function improves with increases in phylogenetic diversity. However, many of these results have been generalized across a range of different species and clades, and plants with different evolutionary histories cou...

Should blood be bought and sold is in crude terms the question ashed and answered by Richard Titmuss in his recent book The Gift Relationship. Dr Raymond Plant, a lecturer in philosophy at Manchester University, analyses Titmuss' argunents in a paper which we are printing in two parts. Titmuss has taken the provision of blood as his example of the gift relationship and by extension that of heal...

in order to estimate the relationship between forage quality and preference value of plant species for raini goats(capra aegagrus hircus), a field study was carried out on raini goats’ grazing behavior in some desert habitats.crude protein (as the most important factor affecting forage quality) of all plant species was measured at twophenological stages (spring and summer, 2010) in the dry rang...

Soil-to-plant relationship/Transfer factor/Radiocaesium/Radiopotassium. In the present study we assessed the radiocaesium uptake by plants in order to piece together information on factors affecting the uptake processes, particularly K supply and plant species differences. Vegetation uptake from soil contaminated by the Chernobyl accident was compared at two semi-natural grasslands. The Cs/K di...

Christy Hoepting, Cornell Cooperative Extension Regional Vegetable Program Steven Beer, Dept. of Plant Pathology and Plant-Microbe Biology, Cornell University It is important to emphasize that “exploring” is in the present tense. In New York, we are just beginning to delve into the fascinating relationship between nitrogen, plant spacing and bacterial diseases of onions. Our preliminary resul...
