Himantura Leopard Lab

299 Words2 Pages

The experiment was done by observing the Himantura leopard and Dasyatis Americana interactions with a school of fishinside a 760,000 gallon tank at the Adventure Aquarium for 90 minutes.There were two Himantura leopard organisms and approximately five to six DasyatisAmericana.A school of fish was observed as three fishes that are approximately three inches away from each other. When either species of stingray came within five inches of the described school of fish, it was marked down if any of the fishes in the school separated from the school by swimming in an opposing direction of the other fishes of the school. If a fish separated from the school, it was marked down as “break apart” for the specie of stingray that caused the separation. …show more content…

By choosing theDasyatisAmericana as control specie, the experiment was able to control for factors such as size and the specie type. The results are intended to give insight into if color patterns act as a warning sign to the prey that the predator stingray is poisonous. Inside the aquarium, the Himantura leopardis not poisonous as a measure of protection to the other species in the fish tank.As the observer, I had no manipulation of the fish tank. There were variations that occurred during the experiment that could not be controlled as during the beginning of the observation, feeding was

  • Pillbug Lab Report

    989 Words  | 4 Pages

    Abstract: The main focus of this lab is on animal behaviors in terrestial isopods, also known as pillbugs. There are many purposes to this lab experiment. First, these pillbugs are put into four different types of enviroments, also known as chambers, light v. dark, hot vs. cold, moisture vs. dry, and lastly shelter vs. open. In these different chambers, there are 10 pillbugs, 5 placed into each individual chamber and then observed for up to 5 – 10 minutes. In this lab we observed that pillbugs prefer light areas, hot temperatures, moist environments, and lastly sheltered spaces.

    The Jararaca Pit Viper On page 26 of his book, The Lost City of Z: A Tale of Deadly Obsession in the Amazon, David Grann presents information on the Jararaca pit viper. He stated that the Jararaca is the most venomous snake in the Americas. One bite will cause a person to bleed from the eyes and become a corpse piece by piece. I found this interesting because I had never heard of the Jararaca and would like to research more information about them. Throughout my essay I will discuss the physical description, mating and reproduction habits, and behavior of the Jararaca pit viper.

    This behavior was observed in all the three experiments and through the period of observation, isopods seemed to move to different sponges before they settled down behind one of them. The χ2 value was 0.03842932, df was 3 and hence the P value was less than 0.001 which proves that this result is not a result of random probability and is in fact significant and reliable. In Trial 2, the hypothesis was that most isopods would go to the sponge with sucrose solution and our hypothesis was proved correct through the experiment. It was observed that a majority (55%) of the isopods preferred sucrose relative to the other sources of moisture.

    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.

    Natural Selection is the concept that organisms better adapted to their environment tend to survive and produce more offspring. This leads to the creation of populations and diversity of life within them. In the Skittlefish Lab, many separate occurrences can be observed which detail and explain how Natural Selection works on a population over a period of time. Certain adaptations in a species in its entirety may display how individuals impact the whole population as they pass their traits onto their offspring, which do the same. This lab required students to observe the individual “Skittlefish” and “Sea M&Ms” in different environments as they camouflaged and hid from predators.

    An interesting feature of this lake is that it contains no large mouth predators of the fish. Normally, the spines of the fish keep them protected from these predators, but here in Bear Paw Lake, the spines actually decrease the fitness of the fish because the dragonfly larvae living at the lake bottom prey on the fish by grabbing them by their spines. Due to natural selection, eventually the fish in the lake population lost their spines on the undersides of their bodies.1 The fish that had low fitness due to their spines were killed and unable to produce offspring while those without spines or maybe with reduced spines lived long enough to

  • To Study The Effect Of Daphnia And Stimmutant

    917 Words  | 4 Pages

    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.

    Relationships Provide an example of: Mutualistic Relationship (both benefit) Coral and Crabs The relationship between Trapezia Crabs and Pociollopora coral on the reefs of Rottnest Island is an example of mutualism as both of species benefit from the interaction with the other organism. The Trapezia Crabs, often called ‘coral crabs’ live amongst the branches of coral and feed on the nutrient-rich mucus it produces, but does not induce any harm on the coral. In return, the crabs provide a form of protection for the coral from many of their predators, and would actively defend the coral from sea stars such as the Crown of Thorns (Acanthaster planci) which is a major treat to the coral. Therefore, the Trapezia crabs and Coral are an example of a mutualistic relationship.

  • Pacific Salmon Environmental Analysis

    It is asserted that this increase in the number of salmon is due to a bottom-up effect, which increases resources salmon need, benefitting the species and allowing a population increase. An increase in water temperature has been shown to increase zooplankton populations, and this gives salmon fry a higher rate of survival. As temperatures have increased, salmon also develop faster and stay sheltered longer, evading predators more. When the water is at a cooler temperature, there are less zooplankton, slower fry development, and an increased vulnerability to predators. This observed increase in pink salmon populations has lead this species to have a top-down effect on other salmon species.

  • Predator-Prey Lab Report

    Introduction Predation is a biological interaction between two organisms of different species in a community in which one acts as a predator and captures and feeds on the other, the prey. Predator-prey relationships keep animal populations in balance. When prey populations increase more food is available for predators, and they increase in number as well. An increase in predators triggers a decrease in prey populations. As prey populations decrease predator populations soon follow as their food supply diminishes.
