Testing the standard neutral model of biodiversity in lake communities
Steven C. Walker,Hélène Cyr +1 more
TL;DR: In this paper, the authors tested the fit of the neutral model to fish, zooplankton and phytoplanktons in 30 well-studied lake communities varying widely in lake size and productivity.
Journal ArticleDOI
Functional rarefaction: estimating functional diversity from field data
TL;DR: In this article, the authors use the rarefaction technique from species richness studies to address sample-size-induced bias when estimating functional diversity indices, which transforms any given MSR index into a family of unbiased weighted indices, each with a different level of sensitivity to rare species.
Journal ArticleDOI
Scalable gas-phase purification of boron nitride nanotubes by selective chlorine etching.
Hyunjin Cho,Steven C. Walker,Mark Plunkett,Dean Ruth,Iannitto Robyn,Yadienka Martinez Rubi,Keun Su Kim,Christa M. Homenick,Andreas Brinkmann,Martin Couillard,Stéphane Dénommée,Jingwen Guan,Michael B. Jakubinek,Zygmunt J. Jakubek,Christopher T. Kingston,Benoit Simard +15 more
TL;DR: In this article, the authors present a process to manufacture nanotubes at commercial scales and show that after manufacturing, purification is necessary and is a necessary and sufficient condition for nanotube production.
Journal ArticleDOI
Using phylogenetic information and chemical properties to predict species tolerances to pesticides
TL;DR: A statistical modelling approach is proposed to predict tolerances associated with untested species–substance pairs, by using models fitted to tested pairs based on the phylogeny of species and physico-chemical descriptors of pesticides, with both kinds of information combined in a bilinear model.
