A simple mechanism for population cycles
Roger M. Nisbet,William Gurney +1 more
TL;DR: This work has analysed possible models of the mechanisms underlying the regulation of populations in order to simplify the extraction of useful information from specific cases of population oscillation.
Journal ArticleDOI
The Implications of Experimental Design for Biodiversity Manipulations.
TL;DR: This study affirms the common conclusion of many published biodiversity experiments that loss of biological diversity is often associated with a reduction in ecosystem functioning and demonstrates that interpreting results about mechanisms from biodiversity experiments will be critically dependent on an experiment's design.
Journal ArticleDOI
Evolution of phenotypic clusters through competition and local adaptation along an environmental gradient
TL;DR: Analysis of the evolution of a quantitative trait in populations that are spatially extended along an environmental gradient, with gene flow between nearby locations shows that the shape of competition kernels is important for clustering: the sign structure of the Fourier transform of a competition kernel determines whether the kernel promotes clustering.
Journal ArticleDOI
The role of environmental generalist species in ecosystem function
TL;DR: The analyses suggest that the environmental tolerances of species can be an important consideration in determining ecosystem function, and should be considered in asking whether all species, or certain key species, drive the positive relationship between diversity and ecosystem function.
Journal ArticleDOI
Resource Allocation, Coexistence, and the Niche Structure of a Streambank Salamander Community
TL;DR: The community appears to be well coadapted since the following have been demonstrated: total niche overlap is low, therefore minimizing competitive interactions, interspecific predation could not be documented and must be minimal, and demographic strategies are consistent in all macrohabitats regardless of congeneric composition.
