Abstract:
... The productivity and diversity of plant communities are affected by soil organisms such as arbuscular mycorrhizal fungi (AMF), root herbivores and decomposers. However, it is unknown how interactions between such functionally dissimilar soil organisms affect plant communities and whether the combined effects are additive or interactive. In a greenhouse experiment we investigated the individual and ...

Abstract:
... Restoration projects may have broad and complex ecological goals that require distinct and integrative measures for evaluating restoration development and success. However, most studies usually evaluate structural and species composition parameters, with less emphasis on ecological processes and functioning. The main objective of this study is to use an integrated approach that considers structura ...

The relationship between biodiversity and ecosystem functioning (B-EF) was investigated by examining top-down effects of aquatic detritivore diversity on the functional process of leaf-litter breakdown. This study was undertaken in tropical Hong Kong where the stream detritivore guild is depauperate and loss of one or a few species might have strong effects on processes. Effects of detritivore ric ...

Abstract:
... Peat mining causes major degradation to bogs and natural regeneration of these sites is slow and often incomplete. Thus, restoration is an important tool for re-establishing natural ecosystem properties (although perhaps not the original species pool) in mined bogs. Because faunal recovery cannot be taken for granted following plant restoration, we assessed community assembly of higher flies (Dipt ...

Abstract:
... Theory suggests that bottom‐up effects of resource diversity to upper trophic levels increases ecosystem functioning. In particular, energy flux from the detritus to other organisms in an ecosystem affects food web dynamics. To our knowledge, no empirical studies have examined how detritivore diversity alters the energy flux to upper trophic levels in a food web. Here we test the hypothesis that t ...

Abstract:

Because copepods are a key link in marine food webs, their response to environmental changes is an important topic in marine biodiversity and ecosystem functioning relationships. The relationship between copepod assemblag ...
