The highest diversity (52 taxa) was observed in the sample # 9 (Table 1), a population which is represented by all ecological groups of testate amoebae--that is eurybiont, pedobiont, sphagnobiont, hydrobiont
, acidophilic, and calcific.
The carbon number distribution is [C.sub.11]~[C.sub.38], the parity advantage is not obvious, the maximum carbon number is [C.sub.17]~[C.sub.21], and [summation] [C.sub.21.sup.-]/[summation][C.sub.21.sup.+] ranges from 0.77 to 2.47 (Table 2), indicating that the crude oil is composed by hydrobiont
and terrigenous plants and the aquatic bacteria play an important role.
In-depth study has been done on the various aspects of the microflora of the digestive tract of fish but data about the impact of xenobiotics on the intestinal microflora of hydrobiont
Pharmacological analysis of the pathogenesis of acute poisoning with the synthetic pyrethroid cypermethrin using the hydrobiont
Daphnia magna Straus.
