requirements specifying speciation and serotyping in addition to reporting of presence or absence
Each vertex of the tree, except the leaves, might represent a speciation event.
It is sometimes suggested that speciation occurs too rarely or too slowly for any single person to observe a speciation event during their life-time.
The Heliconius heurippa butterfly appears to be the product of a process called hybrid speciation.

Computation codes for speciation analysis were evaluated and tested in interactive exercises.
In an ecological context, host specificity may be a major driving force for speciation in parasitic plants.
This report by Robert Davidson examines the role of coal chlorine on the speciation of mercury in coal combustion flue gas.
By measuring genetic divergence between populations using molecular markers, I hope to relate this host specificity to the process of incipient speciation.

My research focuses on how host specificity can drive speciation in Orobanche species native to the UK.
In contrast, relatively little is known about the influence of phytoplankton on trace metal speciation in coastal waters.
We have previously investigated the speciation of concentrated Hg in sulfidic solutions at high pH at Daresbury Laboratory station 16.5.
