Verification of one-shot rarefaction of the sperm in the insemination operation.
This work has got a task to verify fertilization ability at one-shot rarefaction of sperm, to simplify insemination and to eliminate the second stage of rarefaction. The diluents KARE I and KARE II were used for experiment. The resu...

Uniqueness of rarefaction waves in multidimensional compressible Euler system
We show that 1-D rarefaction wave solutions are unique in the class of bounded entropy solutions to the multidimensional compressible Euler system. Such a result may be viewed as a counterpart of the recent examples of non-uniqueness of the ...

Stability of planar rarefaction waves under general viscosity perturbation of the isentropic Euler system
We consider the vanishing viscosity limit for a model of a general non-Newtonian compressible fluid in Rd, d=2,3. We suppose that the initial data approach a profile determined by the Riemann data generating a planar rarefaction wave solutio...

Identification of nest predators: a sampling perspective
sample size is not increasing. Thirty-one case studies (n = 5 events) reported 6-70 of predator species increased with a 0.50?0.09 (SE) power of sample size across studies-sample species accumulation curve reached an obvio...

Comparison of different sampling methods for evaluation of biodiversity of bugs (Heteroptera) in a birch forest.
The effectivity of sampling methods was assessed using the rarefaction method with abundant samples from shaking down and photoeclectors. Biodiversity measures depends on the sampling method, the lowest were in the...

Bias in vegetation databases? A comparison of stratified-random and preferential sampling
-random instead of preferential sampling. To explore how these two sampling schemes affect vegetation analyses, we compare parameters of vegetation diversity based on preferentially sampled plots from a large veget...

Effect of sample size and resolution on palaeomalacological interpretation: a case study from Holocene calcareous-fen deposits
This study investigates the effects of sample volume, resolution tested (i) if, and to what extent, small sample sizes impoverish the reconstructed mollusc species richness, and (ii) whether fine-resolution sampling is wort...

Rarefaction and extrapolation with beta diversity under a framework of Hill numbers: The iNEXT.beta3D standardization
Based on sampling data, we propose a rigorous standardization method to measure. Richness-based beta diversity (q = 0) quantifies the extent of species identity shift, whereas abundance-based (q > 0) beta diversity...
