In this scientific work are exposed some principles of research on the biology, ecology,
ethology and phenology of green ranides, which are extremely important in the use of certain adequate
and efficient concepts of species identification, among them a place of major importance is occupied by
the biological and morphological concept, although each of them, taken separately, represents and certain
For this purpose, the authors realised a complex study and determined a certain level of
morphological, physiological, ecological and ethological specialization, which, on the one hand, ensure
their existence in different environmental conditions of natural habitats, and on the other hand, allow
them to colonize at large and various anthropic habitats, especially those habitats that offer, first, minimal
but sufficient conditions, for the realization of the process of growth, development, reproduction and the
formation of new generations.
