In the recent past, with the development of molecular systematics, PCR techniques and sequence analysis of the 18S rRNA gene have been used for diagnostics and for characterization of clinical and environmental Acanthamoeba isolates [ 4, 21– 25].
This work has been undertaken to investigate systematics in Al TM alloying energetics, and to augment available calorimetric data for enthalpies of formation in support of the development of accurate multicomponent thermodynamic databases for these technologically interesting systems.
With the development of the synthetic theory of evolution in the early 20th century, classification and phylogeny-tracing ceased to be pursued for their own sake, but the theoretical and philosophical underpinnings of classification, known as systematics, became a topic of great interest.

Phylogenetic results are discussed in the light of current systematics and morphology.
Many of the volumes are literature surveys or monographs in the area of plant systematics.
The organization also facilitates international cooperation among botanists working in the fields of plant systematics, taxonomy, and nomenclature.
The journal also contains sections devoted to the International Organisation of Plant Biosystematics, reviews and notices of books and other publications, and news in the world of plant systematics.
Although no freely replicating badnaviruses were detected, the sequences help in the study of phylogeny, systematics and reproductive biology.
In the vernacular of traditional systematics, this leap is called "discontinuous variation", so the principle has precedent.
