Bryophyte biomass and species richness on the Park Grass Experiment, Rothamsted, UK

摘要: The relationships between bryophyte biomass and species richness soil pH, nutrient applications vascular plant were analyzed for the Park Grass Experiment (Rothamsted, UK). study examined abundance of bryophytes in relation to long-term fertilizer lime application treatments recently being ceased on some plots. probability present a plot increased with increasing plots at pH 3.3–4.5, lowest values this experiment, there virtually no mosses present. Total decreased richness. Both showed curvilinear response pH. Bryophyte was markedly where nitrogen (N) fertilization had been ceased. common individualistic responses treatments. N negative effect Brachythecium rutabulum. Increasing phosphorus (P) potassium (K) together, positive Eurhynchium praelongum. This also negatively affected by N, but tolerated larger amounts it (100–150 kg ha−1 N) than B. An ephemeral moss, Bryum subapiculatum, unimodal P, K or other explanatory variables.
