A comparison of the various analytical techniques is provided, and a separate chapter handles speciation analysis.
The isolate was sent to the Allegheny County Health Department for further testing and speciation. It was first tested with a fluorescein-conjugated antibody for Neisseria gonorrhoeae; results were negative.
The biologists were slow starters to accept the new developments particularly because of the involvement of mathematics and the omission of many issues such as speciation that were of great importance to evolutionists.
The data for this paper was obtained with an Excel-based equilibrium model that accounts for ion exchange, ion activities, oxalic acid speciation and precipitation (4).
One of the most hotly debated aspects of the speciation process is its geographical context, and the nature and importance of isolation in the initial divergence of taxa (Coyne & Orr 2004).
There's little doubt that the hippie heyday helped usher in what the anthropologist Grant McCracken has called an age of "plenitude," a "quickening speciation of social groups." We live in a looser, less uptight America thanks to the antics of San Francisco's Diggers, New York's Fugs, and every anonymous longhair in between.
Parts on residence time, forcing, the carbonate system, water speciation and water-rock reactions are particularly heavy going.
Eggert thinks the elephants' speciation (separation into a new species) began more than 2 million years ago, when West African elephants migrated away from central and southern African relatives.
Sheryl Berman and Diane Spicer received approximately $91,000 for a year long research project entitled, "Examination of safety, viability and speciation of Lactobacillus dietary supplements in the State of Washington." The work will sample Lactobacillus supplements found on shelves throughout the state of Washington.
