Interest in Elemental Speciation Analysis â¢ Speciation analysis is the analytical activity of identifying and/or measuring the quantities of one or more individual chemical species in a sample. â The chemical species are specific forms of an element defined as to isotopic composition, electronic or oxidation state, and/or complex or molecular structure. â¢ Different forms of an element can have totally different properties. â Essential for predicting and modeling fate, risk, and effects, Critical for toxicology,
Allopatric speciation (from the ancient Greek allos, other + Greek patris, fatherland) or geographic speciation is speciation that occurs when biological populations of the same species become vicariant, or isolated from each other to an extent that prevents or interferes with genetic interchange.he extent to which a geological barrier can effectively isolate a population correlates to the mobility of the organism or its offspring. For example physical barriers such as canyons may effectively block migration and dispersal of small mammals; however, have little impact on flying birds or wind-borne seeds.
