Biodiversity at the edge: a test of the importance of spatial "mass effects" in the Rothamsted Park Grass experiments.
The coexistence of many plant species competing for a few resources is one of the central puzzles of community ecology. One explanation is that different species may be competitively superior in different microhabitats. Many species could then coexist within each piece of a mosaic landscape by what has been termed "mass effects," because subpopulations in areas with negative growth rates would ...
متن کاملThe importance of long‐term experiments in agriculture: their management to ensure continued crop production and soil fertility; the Rothamsted experience
Long-term field experiments that test a range of treatments and are intended to assess the sustainability of crop production, and thus food security, must be managed actively to identify any treatment that is failing to maintain or increase yields. Once identified, carefully considered changes can be made to the treatment or management, and if they are successful yields will change. If suitable...
متن کاملAppendix 1 Methodology for studies on Pochonia chlamydosporia isolates (Rothamsted Research)
Cultures of P. chlamydosporia from infected nematode eggs in soil from different parts of the world have been freeze-dried and retained at Rothamsted Research, prior to use. Eight isolates (five collected from cyst nematode eggs and three from root-knot nematode eggs) were grown on 1.7% corn meal agar (Oxoid, Basingstoke, UK) at 25C prior to use. Chlamydospores used as inoculum were produced in...

متن کاملRequirement of a conservative cytotoxicity assay selection in cellular experiments
Assessment of the cellular effects of natural and/or synthetic products is one of the major goals in biological experiments. This assessment may be conducted at different levels; cellular viability, cellular biological activity, and cellular structure and morphology. Different assays are available for any of above purposes. It is becoming of a routine exercise to apply any of these assays, and ...
