    Abstract In this project, water fleas (Daphnia magna), a semi-transparent freshwater crustacean, are used to study the effects of caffeine on heart 't worry about having to learn how to take a crustacean's pulse: you can actually see the heart beating under a microscope. Many variations of this experiment are possible.

Adults are 1–5 mm in size and reach maturity in 6–12 days (at 20 °C) (Ebert, ). They grow throughout their life with a lifespan, under laboratory conditions, of 50– days. Chapter 7 is on host ranges and discusses what we know about the specificity of Daphnia parasites.

Introduction Daphnia are used to test water toxicity, they are a vital part of fresh water ecosystems. They are a food source for smaller fish and invertebrates and considered to be a consumer of algae and bacteria (Elbert, ). These small crustaceans range in size from mm long and are commonly referred to as water fleas.

Different Daphnia magnas were placed in a depression slide containing fresh water and later exposed to solutions of caffeine and alcohol. Each Daphnia magna had different responses.

These data suggest there is an increase in heart rate when a Daphnia magna is exposed to caffeine and a decrease in heart rate when it is in a solution of alcohol. Materials: 1) cultured daphnia 2) microscope 3) dropper 4) strong brewed coffee 5) dish slide Procedure: 1) Brew a strong pot of coffee to assure a response.

2) Extract a daphnia from the culture using the dropper. 3) Place the daphnia on the dish slide. Make sure the daphnia has plenty of water in the dish. 4) Focus the microscope. Daphnia magna is a small planktonic crustacean (adult length – mm) that belongs to the subclass inhabits a variety of freshwater environments, ranging from acidic swamps to rivers made of snow runoff, and is broadly distributed throughout the Northern Hemisphere and South Africa.

The species has been subject of biological research since the 18th : Daphniidae. Water flea, any member of the crustacean order Anomopoda (class Branchiopoda), a large group containing about species distributed worldwide. Most forms are found in freshwater habitats, but a few occur in marine best known genus is Daphnia, ubiquitous in ponds and streams in Europe and North water flea is microscopic in size, typically.

A daphnia culture is an ideal environment for it to flourish with clear water and nutrients being added continuously by the daphnia. Blanket weed is usually a symptom of too much light. Shade the culture with shade cloth or move it to a more shaded position. Other articles where Daphnia magna is discussed: crustacean: Importance to humans: The water flea (Daphnia magna) and the brine shrimp (Artemia salina) are used as fish food in aquariums and fish ponds, and the larvae of the latter are widely used as food for the larvae of larger crustaceans reared in captivity.

They are a major food. Introduction. Cladoceran zooplankton of the genus Daphnia Muller, is an important component of freshwater food webs (Allen et al., ), and sensitive to a wide range of environmental contaminants (Villarroel et al., ).

Daphnia spp. are widely used as model organisms to investigate the effects of toxicants as well as chemical and physical habitat Cited by: Daphnia are small crustaceans that are inexpensive, easy to care for, and transparent.

The latter property allows students to easily observe the beating heart (Figure 1). Students commonly investigate the effects of chemical agents on heart rate in Daphnia.

Daphnia tend to keep to bodies of fresh water, but some species of Daphnia can survive a high salinity of up to 20 percent seawater.

Typically, Daphnia live in water with a salinity of no more than 5 percent. Most species of Daphnia will thrive in waters with a pH range of between andbut the ideal pH range is between and Daphnia pulex is the most common species of the water flea, an organism which can be found in almost every permanent, eutrophic (nutrient-rich) water body.

A few species are marine, but generally Daphnia, including Daphnia pulex, are freshwater organisms. cean Daphnia magna, but the procedure has never been optimized. We determined the effects of three concentrations of ethanol, nicotine, and caffeine and of a control solution on heart rate in Daphnia.

Ethanol at 5% and 10% (v/v) reduced mean heart rate to ~50% and ~20% of its initial value, respectively. Recovery was rapid after removing 5%.

Environmental Effects of Industrial Run-off on Daphnia magna information that I could not find documented in the IAAAP books. I found out from a local farmer that Brush Creek, a creek that the remediation project had determined was the most contaminated, had at one time run a red, rusty color.

For the non-traditional method I used. These are the sources and citations used to research The effect of caffeine on the Daphnia Magna. This bibliography was generated on.

Daphnia Magna (environmental sciences) science fair projects and experiments: topics, ideas, resources, and sample projects. Daphnia are good organisms for use as an indicator specifically because of their heart. It is visible from a low potency lens, and there is more science behind it. Their normal heart rate, under the most ideal conditions are bpm, which is a little bit more than that of an infant human child.Abstract Do you know that many consumer products, such as sports clothes, cosmetics, and even food containers contain tiny silver particles?
