Daphnia 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 کاملThe dichotomous oxyregulatory behaviour of the planktonic crustacean Daphnia magna.
The dual function of appendage movement (food acquisition, ventilation) proved to be the key to explaining the peculiar oxyregulatory repertoire of the planktonic filter feeder Daphnia magna. Short-term hypoxic exposure experiments with normoxia-acclimated animals under varying food concentrations revealed a dichotomous response pattern with a compensatory tachycardia under food-free conditions...
متن کاملSwimming behaviour of Daphnia clones: differentiation through predator infochemicals
Various characteristics of population and community dynamics of freshwater zooplankton have been studied in the past, in attempts to increase our knowledge of how freshwater ecosystems function. A major leap forward in disentangling ecosystem processes was the discovery of communication based on chemical cues (infochemicals) in the early 1980s. Infochemicals were found to affect many aspects of...
متن کاملTreatment of gonorrhoea with cotrimoxazole, procaine penicillin alone, and procaine penicillin plus probenecid.
Successful treatment of gonorrhoea with cotri-moxazole* has now been reported by several workers who gave one tablet four times a day for 5 days, observed a failure rate of 38 per cent. of the 86 men followed. They claimed that in 45 per cent. of the failures a carrier state resulted which was detected by routine examination of Gram-stained smears in all cases after treatment; cultures were not...
متن کاملThree-Dimensional Analysis of the Swimming Behavior of Daphnia magna Exposed to Nanosized Titanium Dioxide
Due to their surface characteristics, nanosized titanium dioxide particles (nTiO2) tend to adhere to biological surfaces and we thus hypothesize that they may alter the swimming performance and behavior of motile aquatic organisms. However, no suitable approaches to address these impairments in swimming behavior as a result of nanoparticle exposure are available. Water fleas Daphnia magna expos...
