Fertilization effects on species density and primary productivity in herbaceous plant communities
Fertilization experiments in plant communities are often interpreted in the context of a hump-shaped relationship between species richness and productivity. We analyze results of fertilization experiments from seven terrestrial plant communities representing a productivity gradient (arctic and alpine tundra, two old-field habitats, desert, shortand tall-grass prairie) to determine if the respon...
متن کاملEffects of Ontogeny on δ13C of Plant- and Soil-Respired CO2 and on Respiratory Carbon Fractionation in C3 Herbaceous Species
Knowledge gaps regarding potential ontogeny and plant species identity effects on carbon isotope fractionation might lead to misinterpretations of carbon isotope composition (δ13C) of respired CO2, a widely-used integrator of environmental conditions. In monospecific mesocosms grown under controlled conditions, the δ13C of C pools and fluxes and leaf ecophysiological parameters of seven herbace...
متن کاملSoil Disturbance as a Grassland Restoration Measure—Effects on Plant Species Composition and Plant Functional Traits
Soil disturbance is recognized as an important driver of biodiversity in dry grasslands, and can therefore be implemented as a restoration measure. However, because community re-assembly following disturbance includes stochastic processes, a focus only on species richness or establishment success of particular species will not inform on how plant communities respond ecologically to disturbance....
متن کاملEffects of Herbaceous and Woody Plant Control on Longleaf Pine Growth and Understory Plant Cover
fine sandy loam (fine-loamy, siliceous, semiactive, thermic Typic Paleudult) with a slope of 1–10% (Kerr et al. 1980). The other complex (92° 38 W, 31° 8 N at 66 m above sea level) is comprised of Beauregard silt loam and Malbis fine sandy loam (fine-loamy, siliceous, subactive, thermic Plinthic Paleudult) with a slope of 1–5%. Before harvesting, Study 2 was a closed canopy, mature, loblolly pi...
متن کاملEffects of Warming on Chlorophyll Degradation and Carbohydrate Accumulation of Alpine Herbaceous Species during Plant Senescence on the Tibetan Plateau
Plant senescence is a critical life history process accompanied by chlorophyll degradation and has large implications for nutrient resorption and carbohydrate storage. Although photoperiod governs much of seasonal leaf senescence in many plant species, temperature has also been shown to modulate this process. Therefore, we hypothesized that climate warming would significantly impact the length ...
