Morphologically
Astreopora
are distinguished among
the other acroporids by the fact they are found
mainly as massive colonies with large numerous
corallites and reticular coenosteum having a spiky
surface. When describing and identifying the species,
the sizes and shapes of corallites, their number per
colony surface unit; sizes and degree of thickness of
primary septa, the character of metasepta
development; and the simplicity or complexity of the
coenosteum spines split are used.
The essence of doubt taxonomists studying
CNIDARIAN, was not what the concept of type
select with only phenotype as allegedly the sole and
primary means of classification, and not a lack of
opportunity to observe or verify the reproductive
isolation of the species. The problem lies in the
ability to make you refuse bias to any concept of
species-zoological, paleontological or some other
"specificity" of research. You must disengage from
the concept of "species", target the natural biological
research together, and not just some amount of
samples; all the time, be influenced by the fact that the
integrity of these aggregates is determined not to
disparities, and isolation, are they not from the amount
of independent individuals, and of populations. Define
such a set of lighter and more adequately can be based
on its relationship to other sets, rather than on the
relationship between individuals within the same
population. The identification of such aggregate,
sufficiently detached, to describe her and name,
pretending to be the formal taxonomic category. In the
basis of the totality of the specimens lie bottom
cells-settlement of the past and a population.
A clear and precise formulation of the objectives,
clarifying methodological prerequisites, objectives,
methods, and their mandatory constraint, along with
an understanding of the biological meaning of results
of research largely dictate the success of the work.
