Consistent functional response of meadow species and communities to land-use changes across productivity and soil moisture gradients

Popis výsledku v původním jazyce

Questions: Wet meadows have traditionally been managed at low intensity, promoting the co-existence of a variety of plant species. The remaining fragments of these meadows are now being degraded by either mowing abandonment or by agricultural intensification, such as increased fertilization. We tested the theoretical expectation that certain functional traits can explain vegetation changes along gradients of productivity and soil moisture in response to these land-use changes. Location: Zelezne hory Mts., Czech Republic, Central Europe. Methods: We set up a long-term experiment where we applied a full factorial design of fertilization and abandonment to 17 traditionally mown wet meadows covering a broad range of productivity and soil moisture conditions found within the region. Plant functional traits that cover different aspects of plant ecological strategies-plant height, specific leaf area (SLA), leaf dry matter content (LDMC), seed mass and clonality-were used to explain both species and whole community response to land-use change. We employed linear mixed effect models to test for the consistency of functional changes across different productivity and soilmoisture conditions. Results: We found that the functional response of species and whole communities to land-use change was consistent across meadows differing substantially in their productivity and soil moisture. Specifically, irrespective of the local conditions, both fertilization and abandonment selected for tall species within communities, highlighting the effect of increased competition for light. Traits related to a more exploitative strategy in species (higher SLA, more prominent clonal growth and smaller seeds) were consistently favoured with increased fertilization.
