Plant traits associated with resource acquisition strategies (e.g.specific leaf area) change along gradients of soil properties, being the most conservative in resource poor environment and the most dynamic in resource rich environment. Analysis of clonal and bud bank traits for species of alpine communities revield that with decreasing soil quality the most common clonal growth organs were rhizomes, and there was a predominance of perennial bud banks located at the soil surface or below-ground, low rates of lateral spread and long persistence of plant- offspring connections. Further, at the level of the plant assemblage, these clonal and bud bank traits were positively associated with LDMC, and negatively with leaf size and plant height. These observations reinforce the hypotheses about trade-offs between acquisition and retention strategies in plants.
