Experimental Tests of Effects of Plant Productivity and Diversity on Grassland Arthropod Diversity
Because the quantity, quality, and heterogeneity of resources should affect the diversity of consumers, plant productivity, plant composition, and plant diversity may influence the diversity of trophic levels higher up the food chain (‘‘bottom-up’’ control of diversity). Increasing plant productivity may increase herbivore diversity by: increasing the abundance of rare resources (‘‘resource rar...
متن کاملEffects of Grazing and Mowing on Leymus Chinensis Grassland in the Songnen Plain of Northeastern China
Effects of mowing and grazing on a Leymus chinensis grassland in the Songnen plain of northeastern China were studied using eight replicates of four grazing and mowing treatments. Canopy cover and biomass of the dominant species (L. chinensis) were lower, and cover of the halophyte Suaeda corniculata higher, on grazed than ungrazed; ungrazed plots showed a response to mowing, but not grazing; s...
متن کاملModulation of diversity by grazing and mowing in native tallgrass prairie
Species diversity has declined in ecosystems worldwide as a result of habitat fragmentation, eutrophication, and land-use change. If such decline is to be halted ecological mechanisms that restore or maintain biodiversity are needed. Two long-term field experiments were performed in native grassland to assess the effects of fire, nitrogen addition, and grazing or mowing on plant species diversi...
متن کاملResource-Mediated Indirect Effects of Grassland Management on Arthropod Diversity
Intensive land use is a driving force for biodiversity decline in many ecosystems. In semi-natural grasslands, land-use activities such as mowing, grazing and fertilization affect the diversity of plants and arthropods, but the combined effects of different drivers and the chain of effects are largely unknown. In this study we used structural equation modelling to analyse how the arthropod comm...
متن کاملPlant Species and Functional Types’ Diversity in Relation to Grazing in Arid and Semi-arid Rangelands, Khabr National Park, Iran
In arid and semi-arid rangelands, grazing as one of the natural or human induced processes has direct and indirect effects on structure and dynamics of plant community and ecosystems. A study was done to analyze the effects of grazing on plant species diversity and Plant Functional Types‘ (PFTs) diversity of arid and semi-arid rangelands. We analyzed plant richness and diversity data from 75 sa...
