As mentioned above, one of the most controversial hypotheses of White was the stasipatric mode of speciation
, largely based on his extensive studies of karyotypic differentiation in the 'viatica' group of the genus Vandiemenella (White 1978).
One conclusion of the authors is that insect shifts to different plant families have been very conservative speciation
The book is directed at risk assessors and regulators, to emphasize the importance of consideration of speciation
which is hardly taken into consideration as a part of most hazard and risk assessments.
When considering speciation
analysis by HPLC/ICP-MS, there are a number of innovations that have been incorporated over the past few years that have lead to faster, more robust, simpler analyses.
71) There is undoubtedly a correlation between the rates of speciation
and chromosome rearrangement.
Paraphyly at the species level is not uncommon (Funk & Omland 2003), and may even be expected under the scenario of ecological speciation
4 it is demonstrated that the designed CE device enables indeed to perform chromium speciation
This is the officially recognized method for speciation
, which is an advantage.
Investigating the geochemical cycling and speciation
of Hg in aquatic systems is of critical importance to understanding the mechanisms responsible for its accumulation in higher trophic levels.
Sessions throughout the week included inorganic and organic speciation
, methodologies for determining trace elements in complex matrices, food characterization, advanced inorganic methodology, recent requirements for reference materials, dietary supplements, food characterization, and foundations for environmental measurements.
of arsenic compounds in urine is essential for the biological monitoring of inorganic arsenic exposure.
Unfortunately, the authors do not provide data that allow one to determine whether speciation
was facilitated by the examination of thick films.
