“…Recent advances in responses of pollinator networks to climate change are discussed elsewhere in this special issue (Memmott 2010). For soil decomposer communities, habitat fragmentation does not seem to play a major role (Rantalainen et al 2008). Moreover, soil decomposer communities are supposed to be quite general in their decomposition activities and most soil organisms present in the rhizosphere originate from the soil surrounding the plant roots, rather than from further distance (de Ridder-Duine et al 2005).…”

Current predictions on species responses to climate change strongly rely on projecting altered environmental conditions on species distributions. However, it is increasingly acknowledged that climate change also influences species interactions. We review and synthesize literature information on biotic interactions and use it to argue that the abundance of species and the direction of selection during climate change vary depending on how their trophic interactions become disrupted. Plant abundance can be controlled by aboveground and belowground multitrophic level interactions with herbivores, pathogens, symbionts and their enemies. We discuss how these interactions may alter during climate change and the resulting species range shifts. We suggest conceptual analogies between species responses to climate warming and exotic species introduced in new ranges. There are also important differences: the herbivores, pathogens and mutualistic symbionts of rangeexpanding species and their enemies may co-migrate, and the continuous gene flow under climate warming can make adaptation in the expansion zone of range expanders different from that of cross-continental exotic species. We conclude that under climate change, results of altered species interactions may vary, ranging from species becoming rare to disproportionately abundant. Taking these possibilities into account will provide a new perspective on predicting species distribution under climate change.

“…In general, soil organisms seem to be rather resistant to habitat fragmentation (Rantalainen et al, 2008). The habitat scale of decomposers is usually smaller than that of aboveground fauna depending, however, on the body sizes, mobility, and territory sizes of the organisms.…”

“…Here, the dimensions of the alternative habitat patches, and the distance between those patches, matched those observed in natural systems (S. M. Lawrie 1996, unpublished PhD thesis), but we did not detect reduced levels of infaunal movement with decreasing corridor width in addition to the effects of differential habitat quality. Meta-community experiments using belowground soil decomposer organisms also demonstrate weak effects of habitat fragmentation (reviewed in [70]), but both marine sediment and terrestrial soil systems are known to host a highly heterogeneous distribution of decomposer resources (e.g. [35,71]), such that decomposer species may be less susceptible to short-term changes in habitat structure.…”

Habitat structure mediates biodiversity effects on ecosystem properties

Much of what we know about the role of biodiversity in mediating ecosystem processes and function stems from manipulative experiments, which have largely been performed in isolated, homogeneous environments that do not incorporate habitat structure or allow natural community dynamics to develop. Here, we use a range of habitat configurations in a model marine benthic system to investigate the effects of species composition, resource heterogeneity and patch connectivity on ecosystem properties at both the patch (bioturbation intensity) and multi-patch (nutrient concentration) scale. We show that allowing fauna to move and preferentially select patches alters local species composition and density distributions, which has negative effects on ecosystem processes (bioturbation intensity) at the patch scale, but overall positive effects on ecosystem functioning (nutrient concentration) at the multi-patch scale. Our findings provide important evidence that community dynamics alter in response to localized resource heterogeneity and that these small-scale variations in habitat structure influence species contributions to ecosystem properties at larger scales. We conclude that habitat complexity forms an important buffer against disturbance and that contemporary estimates of the level of biodiversity required for maintaining future multi-functional systems may need to be revised.
