Maternal food quantity affects offspring feeding rate in Daphnia magna.
Maternal effects have wide-ranging effects on life-history traits. Here, using the crustacean Daphnia magna, we document a new effect: maternal food quantity affects offspring feeding rate, with low quantities of food triggering mothers to produce slow-feeding offspring. Such a change in the rate of resource acquisition has broad implications for population growth or dynamics and for interactio...

متن کاملDaphnia magna
The cellular architecture of the Daphnia compound eye visual system was studied by using computer-aided techniques. All the neurons in one half of the bilaterally symmetric optic ganglion (OG) were reconstructed in three dimensions from serial electron micrographs. The techniques employed were those developed by Levinthal and collaborators (Macagno, Levinthal, and Sobel, Ann. Rev. Biophys. Bioe...
متن کاملDaphnia magna feeding on Cylindrospermopsis raciborskii: the role of food composition, filament length and body size
We investigated the role of filament length of the toxic cyanobacterium Cylindrospermopsis raciborskii on the grazing of Daphnia magna by providing different food mixtures. It was hypothesized that longer C. raciborskii filaments would reduce the clearance rates of D. magna more than shorter ones. Also, C. raciborskii was expected to have a stronger negative impact on the grazing of larger anim...
متن کاملCox-2 Inhibitors Increase Heart Rate in Daphnia Magna
In this investigation, I set out to confirm or possibly disprove the notion that Cyclooxygenase-2 (Cox-2) inhibitors causes increased cardiovascular (CV) risk. To state my objective more precisely, I wanted to find a relationship between hear rate and concentration that would look like a y = IxI (these bars are the absolute value notation) graph where x> 0 (“x” being concentration, and “y” bein...
