  1. Sierra Nevada meadows: species alpha diversity

    Plant species diversity refers to variety and abundance; it does not necessarily relate to meadow health but may provide information important in an ecosystem context. Monitoring to detect change in diversity usually begins with estimating alpha (within) diversity of plant communities. Because few such estimates exist for meadow site classes or specific sites of the...

  2. Herb layer diversity and phytoindicative evaluation of habitat conditions of forest permanent plots in Poland

    The influence of climatic and pollution gradients was determined on species richness, species diversity, and values of phytoindicators of the herb layer in pine and mixed pine forest communities in Poland. Geographical longitude was used as a synthetic measure of geographical position. Ellenberg's indices were used as synthetic measures of habitat differentiation...

  3. Impact of ungulate exclusion on understorey succession in relation to forest management in the Intermountain Western United States

    Questions: Do successional trajectories in plant diversity, heterogeneity and dominance respond differently to ungulate exclusion in unmanaged forests vs managed forests that are thinned and burned? Is vegetation in recently thinned and burned standsmore sensitive to changes in the grazing regime?
