“…Dispersal is costly (Bonte et al, 2012), and the degree to which local populations are effectively linked by dispersal, i.e. connectivity (Calabrese and Fagan, 2004), varies. Dispersal can be a rare event occurring during well-defined periods of the life cycle, as for sedentary individuals, but may also be a consequence of more gradual diffusion processes (Clobert et al, 2009).…”

“…structural connectivity of resource habitats) affects the dispersal of soil microfauna and the resulting community dynamics is not well understood. Tests of how the configuration or size of resource patches affects the dispersal and spatial population dynamics of soildwelling animals have focused on soil macrofauna such as beetles and ants and mesofauna such as springtails (Benton and Bowler, 2012;Ingimarsdóttir et al, 2012;Lehmitz et al, 2012), and less on soil nematodes (but see Bukovinszky et al, 2012). Because of their much smaller body size and the inherent difficulty of observing soil organisms given the opaqueness of soil, studying community dynamics of soil microfauna such as nematodes and rotifers is challenging.…”

Abstract. The spatial distribution of resources affects ecological processes at all levels of biological organization. However, it remains to be tested how the spatial configuration of belowground resources affects the community dynamics of soil organisms and resulting plant–soil feedbacks. We used Agrostis stolonifera plants in different spatial configurations in mesocosms to study the dispersal patterns of soil nematodes and rotifers. Plant–soil feedbacks were later assessed by re-sowing the mesocosms with Lolium perenne and Plantago lanceolata after removing all the initial A. stolonifera plants from the mesocosms. Bacterial-feeding nematodes and rotifers spread fast, whereas plant-feeding nematodes barely dispersed from the release sites. These spread patterns of nematodes and rotifers depended on the life-history traits and not on the spatial pattern of the plants. However, more clustered plants developed a higher total biomass and caused a reduced growth of the subsequent vegetation. Our results demonstrate that the mere spatial pattern of a single plant species can alter the strength of plant–soil feedbacks. This has important implications for understanding the impact of planting or replanting schemes and other changes in the spatial configuration of plants on long-term vegetation development and succession.
