Functional traits as indicators of fodder provision over a short time scale in species-rich grasslands.
BACKGROUND AND AIMS Fodder provision in species-rich grasslands, i.e. herbage growth, proportion of leaf, and leaf and stem digestibility, is difficult to predict for short periods of time, such as between two defoliations or less. The value of two methods based on plant traits for evaluating these agronomic properties was examined. METHODS One method is based on plant trait measurements on t...
متن کاملPlant Trait Assembly Affects Superiority of Grazer's Foraging Strategies in Species-Rich Grasslands
BACKGROUND Current plant--herbivore interaction models and experiments with mammalian herbivores grazing plant monocultures show the superiority of a maximizing forage quality strategy (MFQ) over a maximizing intake strategy (MI). However, there is a lack of evidence whether grazers comply with the model predictions under field conditions. METHODOLOGY/FINDINGS We assessed diet selection of sh...
متن کاملImpact of nitrogen deposition on the species richness of grasslands.
A transect of 68 acid grasslands across Great Britain, covering the lower range of ambient annual nitrogen deposition in the industrialized world (5 to 35 kg Nha-1 year-1), indicates that long-term, chronic nitrogen deposition has significantly reduced plant species richness. Species richness declines as a linear function of the rate of inorganic nitrogen deposition, with a reduction of one spe...
متن کاملFine-scale community and genetic structure are tightly linked in species-rich grasslands.
Recent evidence indicates that grassland community structure and species diversity are influenced by genetic variation within species. We review what is known regarding the impact of intraspecific diversity on grassland community structure, using an ancient limestone pasture as a focal example. Two genotype-dependent effects appear to modify community structure in this system. First, the abunda...
