FINAL REPORT

there are 391 invertebrate species of 167 genera, 35 families, 8 orders and 5 classes recorded
and among them there are 346 species of beetles belonging to 127 genera and 15 families.
Microsomia
Soil is one of the important components in biogeocoenosis and therefore it constitutes an
indispensable part of biosphere. Soil fertility is dependent on microorganisms inhabiting soils.
The microorganisms in the soils are found in different parts of soils depending on aggregate
temperatures, moisture, air, and nutritive substratum rates of soil surface and depth. Growth
and distribution rates of micro-flora species in soils are widely affected by the environmental
factors i.e. air temperature, soil acidity, saline rates and amounts, soil mechanical components,
and features of vegetation.
Plants grown in soils emerge organic compounds i.e. glucose, organic acid and amino acid
into the environment and these organic compounds positively affect the nutrition and growth
rates of microorganisms in soils. Therefore, sticking of microorganisms to either plant root
system or conspicuous parts is not occasional and casual. Microorganisms nearby plant roots
in soils are called rezo-spherical microorganisms and these microorganisms produce nutritive
elements necessary for plant growth by taking place in organic substance cycling process in
soils.
These microorganisms break down poisonous compounds into non-poisonous compounds for
the plants. Microorganisms growing on plant leaves and stems are called as epidit
microorganisms and 80 % of them are Erwinia herbicola bacteria. The microorganisms are
usually on fruit seeds and berries and their growth rates depend on seed moisture and
temperature.
Flora Species (Phytocoenosis)
Detailed studies and research on flora species deal with identification of plant species
compositions, and original and historical development aspects of flora species through
conducting analysis on different aspects. Additionally, the studies and researches provide
references on dominant and economically valuable plant species and their ranges and
distributions within certain areas. Table 20 shows composition of plants recorded in the
vicinity of Buyant River.
