Research Paper On Daphnia

259 Words2 Pages

What is a Daphnia? A daphnia is an invertebrate with an exoskeleton belonging to the aquatic group Crustacea. The crustacean identification is also as water fleas since their locations are in freshwater rivers, lakes, and ponds. These water fleas produce over 200 species, but the most easily accessible ones are D-Magna and D-Pulex. Its clear carapace (upper shell) allows the visibility of its heart and eggs as it moves in an erratic motion.
Metabolism
The daphnia’s main composition consists of a midgut, hindgut and an esophagus running from its head down its body, using one compound eye as an aid in swimming. The position of the heart is right above where the location of eggs in the females back. The water flea’s usual food source is

    Stop 1 – Stinky Cove/Fossil Point. After loading the bus we headed east on Cape Arago Highway until we got to fossil point. We parked and unloaded the bus and began walking along the small exposed sandy beach. At the bend we stopped and were asked to find a fossil, as I wandered around I couldn’t find much other than the ground up shells mixed in with the seaweed and sand. As we continued to walk we came to another spot where we were able to observe scallop fossils mixed with the rock it was coarse and grainy much like sandpaper.

    Daphnia Magna are small crustaceans that are excellent for observing the effect of depressants on their nervous system. The purpose of this specific experiment is to observe the effect of ethanol, aspirin, and caffeine on daphnia’s heart rate. Not only do these chemicals affect heart rate, but they also affect the frequency of reproduction, number of eggs produced, and body structure. Pesticides similar to these chemicals can be released into the environment and daphnia re useful in monitoring toxicity levels. The agents being tested in this experiment can be administered to determine the effects of hormones, stimulants, antidepressants, and neurotransmitters.

    Daphnia magna is a transparent water flea species found in rocky pools along the Atlantic Ocean. The Daphnia’s body is encased in a clear structure called carapace (Elenbaas, 2013). The exoskeleton, carapace, provides protection for the Daphnia magna, “The portion of the hard exoskeleton, or shell, that covers all or part of the body of many crustaceans…” (“Definition, n.d.). The heart can be easily seen under a light microscope due to the transparency of the skin (Handy, 2012).

    The following experiment determines the effects of 50 ml tobacco extract on the heart rate of a crustaceans Daphnia Magna. Daphnia represents a small group of aquatic crustaceans, also known as “water fleas”, with clear exoskeletons, which makes studying their heart rate effortlessly. The heart rate can be observed using a microscope and counted under varying conditions. (Pritchard, J. B.) In this case, changing the type and concentration of natural plant substances reveals the effects of the plant defense mechanisms on the specimen of Daphnia Magna.

  • To Study The Effect Of Daphnia And Stimmutant

    Daphnia are grown as fish food, and used to test ecotoxicity. Ecotoxicology is defined as, "the branch of toxicology concerned with the study of toxic effects, caused by natural or synthetic pollutants, to the constituents of ecosystems, animal (including human), vegetable and microbial, in an integral context” (Truhaut, 1977). The experiment discussed in this lab report was performed on daphnia, exploiting their transparency which renders them the ideal organism, to test effects of various stimulus on cardiac activity. Past research studies have found ethanol to produce a depressant effect, one similar to the depressant effects of melatonin, and GABA. In contrast, Corotto (2010) has experimented on stimulants, e.g. nicotine, and found an approximate 20% increase in HR.

    They create a well balanced ecosystem by being the prey of amphibians and small water insects and eating algae found in ponds and lakes. When there is not Daphnia present in lakes and ponds, an increase of algae and decrease of fish can be seen. Because of their sensitivity to the surroundings and its transparent carcass, when Daphnia are in hypoxic conditions, more hemoglobin is produced and they appear red. Hypoxic is when the body or part of the body is lacking adequate oxygen supply. This red color can be seen about
