Biodiversity and litter decomposition in terrestrial ecosystems

Article Abstract:

A study on the empirical and theoretical evidence for functional significance of plant-litter diversity and the extraordinary high diversity of decomposer organisms in the process of litter decomposition and the consequences for biogeochemical cycles is presented. Litter species and decomposer diversity can significantly influence carbon and nutrient turnover rate but no general or predictable pattern has emerged.

Insects on plants: Diversity of herbivore assemblages revisited

Article Abstract:

Analyses of countrywide insect-host catalogs, field studies of local herbivore communities and comparative studies at different spatial scales are presented. Methods of community phylogenetic analysis, complex networks, spatial and among-host diversity partitioning, and metacommunity models present approaches for future work.

Indirect interaction webs: Herbivore-induced effects through trait change in plants

Article Abstract:

A study to explore the herbivore-induced indirect effects mediated by plant responses due to herbivory in terrestrial systems is presented. The herbivore-induced indirect effects result in interaction linkages, which alter species richness and abundance in arthropod communities.
