Differential response of communities of plants, snails, ants and spiders to long-term mowing in a small-scale experiment

摘要: We examined the response of communities four groups organisms (plants, snails, ants and spiders) in a small scale mosaic 8-years mown unmown plots wet meadow Central Europe. The experimental setup consisted 7 8 regularly 4 m2 checkerboard arrangement. Eight years after start experiment, plant community structure diverged to mowing/nonmowing, both species composition structure. Both bryophyte vascular numbers were significantly higher plots. In plots, bryophytes nearly disappeared dominated by tall tussock grass Molinia caerulea. diversity abundance snails than ones. Ant nests more abundant differed between captured individuals spiders but we did not find any difference composition. conclude that duration different management was sufficient establish low movable organisms, whereas these are probably too host assemblages with good active dispersal abilities.
