Biodiversity and Ecosystem Functioning
Species diversity is a major determinant of ecosystem productivity, stability, invasibility, and nutrient dynamics. Hundreds of studies spanning terrestrial, aquatic, and marine ecosystems show that high-diversity mixtures are approximately twice as productive as monocultures of the same species and that this difference increases through time. These impacts of higher diversity have multiple cau...
متن کاملChemical communication in competitive interactions among tropical stream detritivores
The role of chemical communication among competitors in streams is virtually unknown, especially in tropical streams. In this study, we experimentally examined the ability of four tropical invertebrate shredders (Anisocentropus kirramus Neboiss 1980, Lectrides varians Mosely 1953, Triplectides gonetalus Moser & Neboiss 1982 and Atalophlebia sp.) to detect and respond to chemical cues from compe...
متن کاملAnthropogenic impacts on tropical forest biodiversity: a network structure and ecosystem functioning perspective.
Huge areas of diverse tropical forest are lost or degraded every year with dramatic consequences for biodiversity. Deforestation and fragmentation, over-exploitation, invasive species and climate change are the main drivers of tropical forest biodiversity loss. Most studies investigating these threats have focused on changes in species richness or species diversity. However, if we are to unders...
متن کاملBiodiversity and ecosystem functioning in dynamic landscapes.
The relationship between biodiversity and ecosystem functioning (BEF) and its consequence for ecosystem services has predominantly been studied by controlled, short-term and small-scale experiments under standardized environmental conditions and constant community compositions. However, changes in biodiversity occur in real-world ecosystems with varying environments and a dynamic community comp...
متن کاملBiodiversity and Ecosystem Functioning: Experimental Systems
Experimental studies of the relationship between biodiversity and ecosystem functioning have taken two main approaches: the experimental removal of species from real communities and the construction of model communities to form gradients of diversity. The fundamental difficulty in designing biodiversity experiments is the large number of possible species combinations that make simple, unambiguo...
