Complementarity among species in horizontal versus vertical rooting space
Aims: Many experiments have shown a positive effect of species richness on productivity in grassland plant communities. However, it is poorly understood how environmental conditions affect this relationship. We aimed to test whether deep soil and limiting nutrient conditions increase the complementarity effect (CE) of species richness due to enhanced potential for resource partitioning. Methods...
متن کاملChallenging the paradigm of nitrogen cycling: no evidence of in situ resource partitioning by coexisting plant species in grasslands of contrasting fertility
In monoculture, certain plant species are able to preferentially utilize different nitrogen (N) forms, both inorganic and organic, including amino acids and peptides, thus forming fundamental niches based on the chemical form of N. Results from field studies, however, are inconsistent: Some showing that coexisting plant species predominantly utilize inorganic N, while others reveal distinct int...
متن کاملNitrogen acquisition by plants and microorganisms in a temperate grassland
Nitrogen (N) limitation is common in most terrestrial ecosystems, often leading to strong competition between microorganisms and plants. The mechanisms of niche differentiation to reduce this competition remain unclear. Short-term (15)N experiments with NH4(+), NO3(-), and glycine were conducted in July, August and September in a temperate grassland to evaluate the chemical, spatial and tempora...
متن کاملSoil fertility, heterogeneity, and microbes: towards an integrated understanding of grassland structure and dynamics
Objective: To highlight the need and the potential for an integrated understanding of three key soil-based drivers of plant community structure and dynamics – soil fertility, soil heterogeneity, and microbes. Location: European and North American grasslands. Methods: Review and discussion of conceptual models and empirical literature, including examples of observational and manipulative studies...
متن کاملComment on "A reservoir of nitrate beneath desert soils".
Walvoord et al. (1) reported a large nitrate pool located deep ( 1 m) beneath desert soils. Two aspects of this work were particularly surprising: the large pool size, estimated to be up to 10 kilograms of nitrogen per hectare, as nitrate (kg N ha); and the shape of the nitrate profiles, which resembled the conservative solute-accumulation profiles of Cl more than typical nutrient depletion pro...
