بررسی گوناگونی زیستی نیام بالان آبزی در چشمه جویبار قنبری پارک ملی بمو، شیراز، فارس

‏‎the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for their population dynamics except three,two of which were also identified down to the species level in this study and the other one-the only one in the community-remained identified down to the genus level.the expertise acquaintance with the recognition of genera and species and their sex differntiation and their habitat was worked out and practiced-under the close supervision of experts-well prior to the starting of field work so that the identifications be done with precision and cautious certainly in the field,hence the animals collected could be released back to their home after the recordings.mid-seasonal samplings of the whole system is taken for six seasons,from spring 1379 to summer 1380 removing all the populations from wherever they existed in every microhabitat and were safly released back after their genera,species,number of individuals and their males and females were recorded.results are tabulated in space-along the length of stream-and time-six mid-seasons-and in quality-species composition-and in quantity-number of individuals of each sex in each species in related tables. some of these results are shown diagrammatically also.the ststus of coexistence of species pairs and species triplets is worked out statistically.the dynamics of the community and its nature are discussed.further studies following this type of work are recommended.‎‏
