On consideration of the distribution of algal genera
in the present study it is observed that Euglena
and Synedra are genera where niche requirements
are most common and prevalent. These are most
resistant to extinction. Lower down are species of
Gomphonema and Oscillatoria. However species
of Ankistrodesmus, Pandorina, Cyclotella,
Chlamydomnas and Chlorella are highly sensitive
to environmental conditions and therefore appear
occasionally. Species of Euglena, Scenedesmus,
Lepocinclis and Synedra are highly resistant and
are autochthonous in origin and appear regularly
in almost all lakes. The matrix fill of the species in
the present study is low (59.5%). This may be due
to lack of species distribution in the lakes.
Secondly the system temperature is also
considerably warm (34.220
).If the matrix is highly
packed, the system temperature will be colder.
Further, random matrices contribute to the
temperature of the matrix in two ways. One is the
random variation of environmental, demographic
and possibly genetic stochasticity, while the other
is coherent temperature of specific biogeographic
events.
