Are belowground clonal traits good predictors of ecosystem functioning in temperate grasslands?

چکیده
In herbaceous communities which host many perennial species, belowground clonal organs and traits remain largely overlooked in ecosystem functioning studies. However, the compartment is expected to play a key role as greatest proportion of biomass allocated belowground. Our main goal was test whether including underexplored (in tandem with widely used aboveground traits) improves ability predict production soil carbon temperate grasslands. We examined relationships between five plant functional (canopy height, specific leaf area [SLA], lateral spread, multiplication rate, persistence rhizome) allocation (aboveground, roots, rhizomes) organic (SOC). studied 52 grassland plots clustered two Central European regions differing by management intensity. assessed (into roots rhizomes separately). SOC measured from averaging cores at each plot. Trait community means were calculated for trait species compositions using databases. The most important predicting canopy height rhizome. Results, however, differed implying context dependency relationships. Persistence rhizome emerged affecting less intensively managed grasslands—likely because their links economics spectrum. At more grasslands, SLA negatively correlated root biomass, playing (lesser) role. found no significant predictors SOC. Synthesis. This study first attempt integrate carbon. Findings indicate that highly dependent, varying greatly even within same type. Only and, lesser extent, consistently predicted regions. call broader implementation whole-plant multifunctional approach applied here, ideally extending other open ecosystems.

How generalist herbivores exploit belowground plant diversity in temperate grasslands
Belowground herbivores impact plant performance, thereby inducing changes in plant community composition, which potentially leads to cascading effects onto higher trophic levels and ecosystem processes and productivity. Among soil-living insects, external root-chewing generalist herbivores have the strongest impact on plants. However, the lack of knowledge on their feeding behaviour under field...

متن کاملFunctioning in Grasslands
Grasslands are the potential natural ecosystem type on approximately 25% (33x lo6 km2) of the land surface of the earth (Shantz 1954). Current estimates of the global extent of grasslands range from 16% (Whittaker and Likens 1973, 1975) to 30% (Ajtay et al. 1979). The difference between the estimates of the potential extent of grasslands and the current extent provides an indication of the degr...
