    Simulating grazing of a 3-D sward canopy

    The productivity and stability of grazed grassland rely on dynamic interactions between the sward and the animal. Combes et al. record 3-D canopy structures of swards of white clover (Trifolium repens) using an electromagnetic digitizer and adapted software, and synthesize virtual canopies in order to calculate bite mass of grazing animals and to determine effects on […] More

    Viruses and promotion of plant genotypic diversity

    Genotypic diversity is essential for maintenance of plant species. Van Mölken and Stuefer examine White clover mosaic virus and Trifolium repens and show that the effects of virus infection on plant performance can differ greatly between distinct host genotypes, resulting in changes in relative fitness between virus-infected and control treatments. This suggests that virus infections […] More
