Enhanced interannual precipitation variability increases plant functional diversity that in turn ameliorates negative impact on productivity.
Although precipitation interannual variability is projected to increase due to climate change, effects of changes in precipitation variance have received considerable less attention than effects of changes in the mean state of climate. Interannual precipitation variability effects on functional diversity and its consequences for ecosystem functioning are assessed here using a 6-year rainfall ma...
متن کاملPrecipitation variability and primary productivity in water-limited ecosystems: how plants 'leverage' precipitation to 'finance' growth.
indicated that these mutants possess about 50% residual transport activity in vitro (Eren et al., 2007). Furthermore, Wong et al. found that the cytoplasmic C-terminus, which contains three Zn-binding sites and has been speculated to have a regulatory role (Eren et al., 2006), is not essential for HMA2 function in either Zn or Cd transport in planta. In continuation of this work it would be int...
متن کاملGrass-Shrub Associations over a Precipitation Gradient and Their Implications for Restoration in the Great Basin, USA
As environmental stress increases positive (facilitative) plant interactions often predominate. Plant-plant associations (or lack thereof) can indicate whether certain plant species favor particular types of microsites (e.g., shrub canopies or plant-free interspaces) and can provide valuable insights into whether "nurse plants" will contribute to seeding or planting success during ecological re...
متن کاملCharacterization of spatial variability of soil physicochemical properties and its impact on Rhodes grass productivity.
Characterization of soil properties is a key step in understanding the source of spatial variability in the productivity across agricultural fields. A study on a 16 ha field located in the eastern region of Saudi Arabia was undertaken to investigate the spatial variability of selected soil properties, such as soil compaction 'SC', electrical conductivity 'EC', pH (acidity or alkalinity of soil)...
متن کاملTemporal variability in aboveground plant biomass decreases as spatial variability increases.
Ecological theory predicts that diversity decreases variability in ecosystem function. We predict that, at the landscape scale, spatial variability created by a mosaic of contrasting patches that differ in time since disturbance will decrease temporal variability in aboveground plant biomass. Using data from a multi-year study of seven grazed tallgrass prairie landscapes, each experimentally ma...
