Population – Structural and Functional Basic
Element of Bioceonosis and Species. The Role
of Population in the Knowledge of Species
Autecology
Nicolae Donița ˘ and Stoica Godeanu
Abstract Every species exists in nature only as one or more populations. They
may be investigated in different ways by biologists and by ecologists (in ecology a
special branch deals with population ecology – autecology).
To study the ecology of an individual species does not mean to study autecological peculiarities of a single population, but of a multitude of populations within
the areal of respective species, searching intrapopulational and interpopulational
relationships, their relations to the abiotic environment and the manner of their
participation to processes of production, transfer, consumption and decomposition
of biomass and necromass, as well as the specificity of energy transfer.
The aim and the role of autecological investigations are highlighted, and the
place of this branch among the other fields of ecology. It may be best realized using
intensely the mathematical processing of the data.

30.1 Population, Biocoenosis and Species
Both for biologists and for ecologists the species is represented by a multitude of
individuals which have the same biochemical, genetic, morphologic, physiologic,
behavioral peculiarities, which live under the same environmental conditions,
forming populations in which they live and reproduce. The species must be seen
a single whole. However,
