Chaterghat pond, Chakand and Lakshmipur Pond, Chakand (both from Gaya District) were explored with regard to Periphyton community structure. Species diversity (H) was calculated for both the ponds by using Shannon-Weaver’s equation and found to be more or less same, 2.52283 and 2.66388 respectively. Greater stress of competition for space and resources was observed in Chaterghat Pond, Chakand (J=0.75945) as compared to Laxmipur Pond, Chakand (J=0.88796). Index of dominance (C) and other measure of diversity (D), calculated as D = 1-C, corroborated the above conclusion. Cylindrocapsa sp. amongst the algae was abundant in acidic condition while Rivularia sp. was predominant in neutral condition.
The genus Krimi was established by Burt in 1944 with its type species K. chrysocolaptis,from Chrysocolaptis guttacristatus stricklandi,in Ceylon. Nine specimens of Cestode parasites were collected from the intestine of Gallus gallus domesticus. The present cestode have 55-60 number of strobilla; scolex large, rectangular in shape;rostellar sac large, extends up to the middle of the scolex; 18rostellarhooks; testes 25 to 30in numbers; cirrus pouch medium, oval; ovary is bilobed,each lobe with 7-8 acini;ootype small, oval; gravid proglottids large, broaderthan long.
