- Cover; Contents; Foreword; List of contributors; Acknowledgments; Part I Nonequilibrium and Equilibrium in Populations and Metapopulations; 1 Reef fishes: density dependence and equilibrium in populations?; Summary; Background: the development of ideas about density dependence in reef fishes; The recruit-adult hypothesis; Competition for refuges is a widespread cause of density dependence; The recruit-adult hypothesis expanded: spatial variation in carrying capacity based on availability of refuges; Reef fish populations in decline; Possible links between reef degradation and fish declines.
- The recruit-adult hypothesis expanded: declining carrying capacity for reef fish populations based on loss of refugesIf mesopredator release is occurring, its likely effect is to intensify density-dependent mortality in small prey fishes; Cryptic density dependence and responses of settling larvae to habitat degradation; Conclusion; References; 2 Population dynamics of ectoparasites of terrestrial hosts; Introduction; Measurements of abundance and distribution; Is abundance a parasite species character?; Relationship between abundance and prevalence; Biases in ectoparasite infestation.
- Factors affecting ectoparasite abundance and distributionConcluding remarks; References; 3 Metapopulation dynamics in marine parasites; Introduction; Metapopulations within metapopulations; Spatial patterns of populations and epidemiology; Concluding remarks; References; Part II Nonequilibrium and Equilibrium in Communities; 4 The paradox of the plankton; General background; Competition for resources, competitive exclusion, coexistence and chaos; Conclusions; Acknowledgments; References; 5 A burning issue: community stability and alternative stable states in relation to fire; Introduction.
- Fire begets fire
- the stability paradoxEvidence for transformative fire feedbacks; Evidence of feedbacks from fire exclusion; Global evidence of alternative stable states; Rainforest stability; Aridity, fire and stability; Community stability and invasive species; Conclusion; References; 6 Community stability and instability in ectoparasites of marine and freshwater fish; Introduction; Parasite communities; Non-saturated communities of fish ectoparasites; Aggregation of fish parasites promotes the stability of fish ectoparasite communities.
- Temporal and spatial variability affect the structure of ectoparasite communities in freshwater fishLimiting similarity and niche restriction in ectoparasite species of fish: factors stabilizing the structure of their communities; Host specificity in structuring parasite communities; Nested structure of fish ectoparasite communities; Null model analyses; Conclusions; Acknowledgments; References; 7 Ectoparasites of small mammals: interactive saturated and unsaturated communities; Introduction; Ectoparasite co-occurrence: aggregative structure is a rule; Nestedness in ectoparasite communities.
