speciation

the process by which new species are formed. Speciation occurs when gene flow has effectively ceased between populations where it previously existed and is brought about by ISOLATING MECHANISMS.see GEOGRAPHICAL ISOLATION.

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.
That Tetragnatha do not hybridize, despite the young age of many species, is interesting in comparison with Drosophila and Laupala: In both the flies and crickets, sexual selection has been implicated as a major force in driving speciation (Kaneshiro 1989; Shaw & Herlihy 2000).
This is the officially recognized method for speciation, which is an advantage.
The quality assurance of urine arsenic speciation analysis has recently become a matter of concern.
Although copper contamination of the environment has been investigated intensively since the 1980s, research on copper speciation and associated biogeochemical processes in aquatic ecosystems is scarce, owing to time-consuming analysis techniques and difficulties in characterising the complex organic copper-binding ligand pool.
Plants found on 'extreme' soils, those characterized by unusual chemical (pH, ionic strength, nutrients, or heavy metals) or physical conditions (soil moisture, temperature, texture, structure, or depth), provide model systems to examine the role of edaphic (soil-related) adaptation in ecological speciation (Rajakaruna, 2004; Kay et al, 2011) and adaptive radiation (Ellis & Weis, 2005; Paun et al., 2016; Shimizu-Inatsugi et al., 2016).

Among the numerous influencing factors, pH is one of the main factors, and the effect of pH on the speciation of heavy metals is of great significance to the migration and transformation of metals [15].
After almost 150 years since Charles Darwin wrote "The Origin of Species," laying the foundation of evolutionary biology, scientists have for the first time observed a species evolving into another, a process called speciation.
