The Effects of Temperature on the Swimming Behavior of Daphnia Introduction: Plankton play a large role in the ecosystem. Plankton are aquatic organisms that exist in innumerable different regions of aquatic environments. They can be utilized as a food source for other planktons, large aquatic animals, and other animals. Since they are at the pedestal of the food chain, they are important since they fill the base of the ecosystems they exist in. Many zooplanktons are also ectothermic which means temperature can highly affect metabolism and growth (Jalal et al., 2013). Studies on earlier plankton have shown that temperature plays a significant role in many of their swimming behaviors (Ziarek et al., 2011). There are many types of plankton in aquatic habitats, but one of the most profuse types is Daphnia. Daphnia are excellent organisms to use in experiments because they are sensitive to change, are simple and are inexpensive. They respond quickly to a change in environment because they are such tiny organisms. They are often used to check the acidity of a chemical compound that may be found in water. One of the main types of zooplankton in freshwater temperate systems is Daphnia (Ziarek et al., 2011). Daphnia, also known as water fleas, are small crustaceans that live in fresh water. They serve as an important source of food for fish and other aquatic organisms. Daphnia when observed move in a flea-like motion. They also have a short life span that varies according to the environmental factors it is placed in and the physical attributes the Daphnia contains. The temperature of the environment of Daphnia has a significant impact on the metabolism of the organism (Ziarek et al., 2011). Along with the metabolism, the temperature also affects the egg development, reproduction, and behavior of Daphnia (Ziarek et al., 2011). Since temperature impacts a Daphnia’s life
