The metacommunity concept: a framework for multi-scale community ecology
TLDR
This framework is used to discuss why the metacommunity concept is useful in modifying existing ecological thinking and illustrate this with a number of both theoretical and empirical examples. Expand
Navigating the multiple meanings of β diversity: a roadmap for the practicing ecologist.
TLDR
A roadmap of the most widely used and ecologically relevant approaches for analysis through a series of mission statements is provided, distinguishing two types of β diversity: directional turnover along a gradient vs. non-directional variation. Expand
Drought mediates the importance of stochastic community assembly

  • Biology, Medicine
  • Proceedings of the National Academy of Sciences
  • 30 October 2007
TLDR
The hypothesis that the relative importance of stochastic ecological drift and/or priority effects depend on the harshness of the ecological filter in habitats and the results implicate the critical role for understanding the processes of community assembly when examining patterns of biodiversity at different spatial scales is developed.

Community assembly: when should history matter?
  • J. Chase
  • Biology, Medicine
  • Oecologia
  • 26 June 2003
TLDR
Preliminary evidence for multiple stable equilibria are illustrated from an observational study of small pond communities, and important effects on community similarity, as well as on local and regional species richness are shown. Expand
Using null models to disentangle variation in community dissimilarity from variation in α‐diversity
β-diversity represents the compositional variation among communities from site-to-site, linking local (α-diversity) and regional (γ-diversity). Researchers often desire to compare values ofExpand
Stochastic Community Assembly Causes Higher Biodiversity in More Productive Environments

  • 11 June 2010
TLDR
It is shown that higher β-diversity at higher productivity resulted from a stronger role for stochastic relative to deterministic assembly processes with increasing productivity, which was most consistent with the hypothesis of more intense priority effects leading to multiple stable equilibria atHigher productivity.

Disentangling the importance of ecological niches from stochastic processes across scales

  • Biology, Medicine
  • Philosophical Transactions of the Royal Society B…
  • 27 August 2011
TLDR
A framework for disentangling the relative importance of deterministic and stochastic processes in generating site-to-site variation in species composition along ecological gradients and among biogeographic regions that differ in the size of the regional species pool is developed. Expand
Spatial scale dictates the productivity–biodiversity relationship
TLDR
Evidence is presented for scale-dependent productivity–diversity patterns in ponds that were hump-shaped when the data were viewed at a local scale (among ponds), whereas when the same data were views at a regional scale ( among watersheds), the relationship was positively linear. Expand
Disentangling the Drivers of β Diversity Along Latitudinal and Elevational Gradients
TLDR
It is shown that sampling alone predicts changes in β diversity caused simply by changes in the sizes of species pools, and there is no need to invoke differences in the mechanisms of community assembly in temperate versus tropical systems to explain these global-scale patterns of β diversity. Expand
Ecological Niches: Linking Classical and Contemporary Approaches
TLDR
Jonathan M. Chase and Mathew A. Leibold argue that the niche is an ideal tool with which to unify disparate research and theoretical approaches in contemporary ecology and develop a framework for understanding niches that is flexible enough to include a variety of small- and large-scale processes.
