How the Earth came to have on the order of 10 million species and the impacts of this biodiversity on ecosystems, are long-standing questions in evolution and ecology. I propose that both the evolutionary causes and the ecological consequences of biodiversity share a common origin—unavoidable tradeoffs that organisms face when dealing with multiple limiting factors. Our grassland biodiversity experiments and studies in many other systems have shown that species diversity is a major determinant…

Tree Endophytes: Cryptic Drivers of Tropical Forest Diversity
Overall, tree endophytes in tropical forests are complex, yet critical drivers of forest dynamics and function, and plant-microbe interactions may typically regulate tree diversity, composition, and forest function at neighborhood and even regional scales.
Intra- and intercrop diversification in cereal cropping and effect on pest control
The findings suggest that intrafield diversification may regulate wheat aphids to some extent, but combining the two diversification practices did not result in an interesting trade-off between pest regulation and wheat production in real farming conditions.
Intercropping impacts the host location behaviour and population growth of aphids
Under laboratory conditions, how intercropping wheat and legumes modifies the behaviour of apterous cereal aphids, Sitobion avenae (Fabricius) (Hemiptera: Aphididae), in terms of host plant location and population growth is evaluated.


Understanding this complexity, while taking strong steps to minimize current losses of species, is necessary for responsible management of Earth's ecosystems and the diverse biota they contain.
Declining biodiversity can alter the performance of ecosystems
COMMUNITIES of species and their associated biological, chemical and physical processes, collectively known as ecosystems, drive the Earth's biogeochemical processes1,2. Currently most ecosystems are
Biodiversity and stability in grasslands
ONE of the ecological tenets justifying conservation of biodiversity is that diversity begets stability. Impacts of biodiversity on population dynamics and ecosystem functioning have long been
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
Plant diversity and ecosystem productivity: theoretical considerations.
Three simple models of interspecific competitive interactions in communities containing various numbers of randomly chosen species predict that, on average, productivity increases asymptotically with the original biodiversity of a community and show that both species identity and biodiversity simultaneously influence ecosystem functioning.
Biodiversity and ecosystem stability in a decade-long grassland experiment
It is found that greater numbers of plant species led to greater temporal stability of ecosystem annual aboveground plant production and the reliable, efficient and sustainable supply of some foods, fuels and ecosystem services can be enhanced by the use of biodiversity.
Biodiversity and Function of Grazing Ecosystems
Does biodiversity influence ecosystem function? Darwin believed it did. In Chap. IV of On the Origin of Species by Means of Natural Selection, he wrote (p. 97), “The more diversified in habits and
Anthropogenic environmental changes affect ecosystem stability via biodiversity
Experiments in temperate grassland suggest that changes in biodiversity caused by drivers of environmental change may be a major factor determining how global environmental changes affect ecosystem stability.
Effects of biodiversity on the functioning of trophic groups and ecosystems
A formal meta-analysis of studies that have experimentally manipulated species diversity to examine how it affects the functioning of numerous trophic groups in multiple types of ecosystem suggests that the average effect of decreasing species richness is to decrease the abundance or biomass of the focal Trophic group, leading to less complete depletion of resources used by that group.
Nutrient enrichment, biodiversity loss, and consequent declines in ecosystem productivity
The hypothesis that the long-term impacts of anthropogenic drivers of environmental change on ecosystem functioning can strongly depend on how such drivers gradually decrease biodiversity and restructure communities is supported.
