large areal of an unique type of ecosystem, the living organisms of the biocoenosis
will differ, both qualitatively, and quantitatively. Moreover, they will react differently to abiotic features.
Hence, in comparison with the types of adaptation presented before, which
referred to an ecosystem occupying a certain place within the general areal of
respective ecosystem, now we can see that there are important differences from
north to south, from east to west, differences determined by relief, by exposure to
solar light, differences due climatic, edaphic, chemical and coenotic factors.
In case of eurioic species, hence of that living in different areals and in more
types of ecosystems, appear more complications.
Coming back to autecology, we must agree that the research cannot be
performed “in general”, but concretely, at the population level. Hence, if each
ecosystem is, in fact, unique, then every population of every species (which
represents its biocoenose), is different from the population of seemingly similar
ecosystems (for instance a population from different coral reefs, that from different
eutrophic lakes, from oligotrophic bogs, from oak forests or from alpine shrubs etc).
It results that each ecosystem, though it has the same name, has its own biotope and
biocoenose, which are similar, but not identical with others. Biotope differences
will determine biocoenoses composed by populations of different species, characterized by different structures and functionalities.
So it means that to study the autecology of a species cannot be done by
investigating the « species » in general, not even at the level of a single population,
but processing representative samples from a lot of populations from the same type
of ecosystem, located in various sites. Autecological research must be done very
carefully, very minutely, based on compiling data obtained from a lot of
populations occurring in various ecosystems. You can realize now how difficult is
to study the autecology of an eurioic species which can live in a lot of types of
ecosystems (not only a single type). And all the obtained data must be, continuously, processed mathematically!
Hence, autecology must achieve much more than has been achieved so far.
30.3 Conclusions
Two categories of conclusions can be drawn:
30.3.1 Referring to the Representation of the Species
Through the Component Populations
Species has a twofold conditioning – ecological and genetic.
30 Population – Structural and Functional Basic Element of Bioceonosis and. . .
