Journal ArticleDOI
Quantifying biodiversity: procedures and pitfalls in the measurement and comparison of species richness
TL;DR: A series of common pitfalls in quantifying and comparing taxon richness are surveyed, including category‐subcategory ratios (species-to-genus and species-toindividual ratios) and rarefaction methods, which allow for meaningful standardization and comparison of datasets.
Journal ArticleDOI
Estimating Terrestrial Biodiversity through Extrapolation
TL;DR: The importance of using 'reference' sites to assess the true richness and composition of species assemblages, to measure ecologically significant ratios between unrelated taxa, toMeasure taxon/sub-taxon (hierarchical) ratios, and to 'calibrate' standardized sampling methods is discussed.
Journal ArticleDOI
Microbial biogeography : putting microorganisms on the map
Jennifer B. H. Martiny,Brendan J. M. Bohannan,James H. Brown,Robert K. Colwell,Jed A. Fuhrman,Jessica L. Green,M. Claire Horner-Devine,Matthew D. Kane,Jennifer Adams Krumins,Cheryl R. Kuske,Peter J. Morin,Shahid Naeem,Lise Øvreås,Anna-Louise Reysenbach,Val H. Smith,James T. Staley +15 more
TL;DR: Current evidence confirms that, as proposed by the Baas-Becking hypothesis, 'the environment selects' and is, in part, responsible for spatial variation in microbial diversity, but recent studies also dispute the idea that 'everything is everywhere'.
Journal ArticleDOI
Rarefaction and extrapolation with Hill numbers: a framework for sampling and estimation in species diversity studies
Anne Chao,Nicholas J. Gotelli,T. C. Hsieh,Elizabeth L. Sander,K. H. Ma,Robert K. Colwell,Robert K. Colwell,Aaron M. Ellison +7 more
TL;DR: In this article, the authors extended previous rarefaction and extrapolation models for species richness (Hill number q D, where q ¼ 0) to measures of taxon diversity incorporating relative abundance (i.e., for any Hill number qD, q. 0) and presented a unified approach for both individual-based (abundance) data and sample-based data.

TL;DR: The negative effects of climate change cannot be adequately anticipated or prepared for unless species responses are explicitly included in decision-making and global strategic frameworks, and feedbacks on climate itself are documented.
