Parallel ecological networks in ecosystemsHan Olff
Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 14, 9750 AA Haren, The Netherlands
Philos Trans R Soc Lond B Biol Sci 364:1755-79. 2009..The usefulness of these new ideas is then explored with three very different ecosystems as test cases: temperate intertidal mudflats; temperate short grass prairie; and tropical savannah...

Ecology 93:2353-64. 2012..Our results show that the structure and dynamics of salt marsh food webs cannot be understood except in light of vegetation succession, and vice versa...

Science 336:1432-4. 2012..These findings elucidate the long-term success of seagrasses in warm waters and offer new prospects for seagrass ecosystem conservation...- Large grazers modify effects of aboveground-belowground interactions on small-scale plant community compositionG F Ciska Veen
Community and Conservation Ecology Group, University of Groningen, PO Box 11103, 9700 CC, Groningen, The Netherlands

Community and Conservation Ecology Group, University of Groningen, PO Box 11103, 9700 CC, Groningen, The Netherlands
J Anim Ecol 81:201-13. 2012..Furthermore, diverse grazing assemblages are composed of herbivores of many body sizes (rather than similar body sizes), because these herbivores best exploit the resources of different habitat types... - Alternative mechanisms alter the emergent properties of self-organization in mussel bedsQuan Xing Liu
Department of Spatial Ecology, Royal Netherlands Institute for Sea Research, Yerseke, The Netherlands
Proc Biol Sci 279:2744-53. 2012.... - Vertebrate herbivores influence soil nematodes by modifying plant communitiesG F Veen

Ecology 91:828-35. 2010..Influences of vertebrate grazers on soil nematodes through modification of abiotic soil properties were of less importance... - How well do food distributions predict spatial distributions of shorebirds with different degrees of self-organization?Eelke O Folmer
Animal Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, Haren, The Netherlands
J Anim Ecol 79:747-56. 2010..6. It follows from our analysis that monitoring programmes, habitat selection models and statistical analyses should also consider the mechanisms of self-organization... - Landscape-scale analyses suggest both nutrient and antipredator advantages to Serengeti herbivore hotspotsT Michael Anderson
Community and Conservation Ecology Group, Groningen University, P O Box 14, 9750 AA Haren, The Netherlands
Ecology 91:1519-29. 2010..Our study highlights the collective and simultaneous role of bottom-up and top-down factors in determining ungulate spatial distributions... - Ecosystem engineering by seagrasses interacts with grazing to shape an intertidal landscapeTjisse van der Heide
Community and Conservation Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, Groningen, The Netherlands
PLoS ONE 7:e42060. 2012..Our study exemplifies that interactions between ecosystem engineering by a foundation species (seagrass) and consumption (waterfowl grazing) can increase spatial complexity at the landscape level... - Resource partitioning among savanna grazers mediated by local heterogeneity: an experimental approachJoris P G M Cromsigt
Community and Conservation Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, Haren, The Netherlands
Ecology 87:1532-41. 2006..Our results, however, encourage wider experimental testing of the role of spatial heterogeneity in facilitating the coexistence of potentially competing savanna herbivores... - The Serengeti food web: empirical quantification and analysis of topological changes under increasing human impactSara N de Visser
Community and Conservation Ecology Group, Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 11103, 9700 CC Groningen, The Netherlands

Trends Ecol Evol 25:119-28. 2010..This framework provides a model for understanding the functioning and diversity of ecosystems in general, and unifies how top-down and bottom-up mechanisms depend on common underlying environmental gradients... - Can clade age alone explain the relationship between body size and diversity?Rampal S Etienne
Community and Conservation Ecology, Centre for Ecological and Evolutionary Studies, University of Groningen, PO Box 11103, 9700 Groningen, The Netherlands
Interface Focus 2:170-9. 2012..Thus, we argue that the most parsimonious explanation for the observation that smaller-bodied taxa are more diverse is that their evolutionary clock ticks faster... - Positive feedbacks in seagrass ecosystems--evidence from large-scale empirical dataTjisse van der Heide
Community and Conservation Ecology Group, Centre for Ecological and Evolutionary Studies, Groningen University, Haren, The Netherlands
PLoS ONE 6:e16504. 2011..Our study demonstrates the potentials of SEM to identify and quantify positive feedbacks mechanisms for ecosystems and other complex systems...
