Microscope Image (IMAGE) University of Michigan Caption This is a microscope image of two Daphnia dentifera that fed on different diets and were exposed to a fungal pathogen. The top Daphnia fed on a nutritious green algae. She is larger and has several embryos in her brood chamber but is infected with a virulent fungal pathogen. The animal on the bottom fed on a toxic cyanobacterium. As a result, she is smaller and only has one developing embryo but is not infected with the pathogen (and, therefore, will live longer) Credit Meghan Duffy Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
