Cladoceran filtering rate : body length relationships for bacterial and large algal particles
-In situ filtering rates were determined for six cladocerans and one Calanoid fed either l-km bacteria or 20-pm algae. Food-specific regressions of filtering rate vs. body length for all cladocerans together produced explained variances of 87 and 95% while a combined regression for both food particles plus 6-pm yeast produced an explained variance of 87%. All animals could filter particles of a...
متن کاملConstruction and validation of a body-length-based model for the prediction of cladoceran community filtering rates
The in situ filtering rates of individual crustacean zooplankton were determined with radioactively labeled yeast cells. In six cladoceran species (Bosmina longirostris, Ceriodaphnia lacustris, Chydorus sphaericus, Daphnia galeata, Daphnia pulex, and Eubosmina coregoni), 93% of the variation in filtering rate could be explained as a power function of body length, completely disregarding species...
متن کاملRegulation of cladoceran filtering rates in nature by body size, food concentration, and diel feeding patterns’
Relationships of body length (L) and filtering rate (fl of four Daphnia species and Holopedium gibber-urn were examined in situ during the day’ and night, During the day filtering rates were low and variable. At night filtering rates were higher and more consistent, with large animals filtering at disproportionately high rates. This resulted in regressions of log F vs. log L with intercepts, sl...

متن کاملStudies on length-weight and length-length relationships of a catfish Eutropiichthyes vacha Hamilton (Schilbeidae: Silurifo-
Present study describes the length-weight (LWR) and length-length (LLR) relationships of a freshwater catfish Eutropiichthyes vacha Hamilton from Indus River, Sindh, Pakistan. A total of 281 specimen of E. vacha were collected from fisherman?s catch from February 2005 to January 2006, are used for this study. The parameters a and b of the length-weight relationship were calculated as W= aLb are...
