For some days past, Captain Bonneville had been made sensible of the great elevation of country into which he was gradually ascending by the effect of the dryness and rarefaction
of the atmosphere upon his wagons.
This novel type of data will be analysed using a new rarefaction
method, developed to test mechanistic explanations for biodiversity patterns along ecological gradients.
Based on the OTUs, rarefaction
curve and alpha diversity indexes (i.
Beaucoup d'intentions ont ete contrariees par la rarefaction
des assiettes de terrain.
It is obvious, that when the piston moves down the rarefaction
is caused, which intakes the liquid drug into the vessels.
Since the decoding of the human genome and with the pressure of the rarefaction
of the fossil resources (hydrocarbon, oil), the biomass, extraordinary sources of renewable carbon, constitute a huge reserve of raw materials in industries such as: chemistry, biofuel, paper, textile and food.
Apres avoir insiste sur une gestion [beaucoup moins que]optimale et durable[beaucoup plus grand que] de la problematique de l'eau aux besoins de developpement, la ministre a fait constater que les ressources hydriques dans le bassin [beaucoup moins que]sont limitees voire en rarefaction
continue[beaucoup plus grand que] sous l'effet de plusieurs facteurs, citant les changements climatiques et les besoins pressants lies a la croissance demographique et aux activites industrielles.
Expected and observed heterozygosities in each group were calculated using HW-Quickcheck (Kalinowski 2006), whereas both allele counts and allelic richness after rarefaction
were estimated using HP-Rare (Kalinowski 2005).
Increased cellular senescence and vascular rarefaction
exacerbate the progression of kidney fibrosis in aged mice following transient ischemic injury.
Since bird abundances were different among the different habitats we used rarefaction
to explore if differences in richness and diversity were closely related to abundance.
curves were calculated for the Pennsylvania and New York collections individually and for both states combined using EstimateS (Colwell 2005).
In order to characterize diatom diversity, we calculated species richness using rarefaction
analysis in R (Heck et al.
