Biophysical Ecology
Abstract:
There are many patterns that can be observed throughout our environment. In this experiment, the temperatures of organisms in a biophysical environment were analyzed to see if a pattern could be recognized that was related to the behavior of an ectotherm. An ectotherm is an organism that relies on the environment to regulate its body temperature. Organisms such as Pseudemys (turtles) and Lacertilia (lizards) are examples or ectotherms. After arriving at Maxcy Gregg Park and analyzing the temperatures of four microhabitats within two habitats with infrared thermometers, the temperatures were compared between the microhabitats. Then, one habitat was chosen to analyze the temperatures between temperatures of ectotherms using I-buttons that were placed inside Peeps. After the five Peeps were placed in each microhabitat our predictions were that as the ectothermal organism increased in elevation, the temperature of the organism would decrease do to access to the wind and convection (Biology 301 Handout 2013 Thermal Enviroments). After gathering the temperatures from the I-buttons, over a twenty minute reading in each microhabitat the data was organized in Excel to be placed into an ANOVA calculation to calculate the null hypothesis. Once the p value was compared to alpha (.05) it was determined to be significant because the p value was lower than alpha. Therefore it is clear that the body temperature of an ectotherm could be affected by the elevation of the organism and convection. For future experiments in this subject it would be more beneficial to test microhabitats that vary more in temperature to truly be able to analyze the factors of thermoregulation in microhabitats.
Introduction:
The thermoregulation of ectotherms such as reptiles and insects has increased in “concern about the impacts of global warming on biodiversity… into direct impacts on living animals that remain simplistic” (Kearney, Shine, Porter, 1).

    PURPOSE: The purpose of this experiment is for the students to get a better knowledge with the laboratory tools and techniques. This experiment taught me how to convert between SI units and standard American units of mass, length, temperature, volume and time as well as how to measure the units. Students become proficient in laboratory techniques such as measuring temperature and volume and calculating within them.…

    The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population, and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining life, when changing the beak size to a much larger size we will see that the finch will have no need for further evolution of its beak and that its population will become much more stable and consistent throughout the years.…

    The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns, in part 1, Ag+, Pb+, and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2, the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules were also a major theme as solubility is important in determining whether a reaction will produce a precipitate.…

    Introduction: The biological membranes are composed of phospholipid bilayers, each phospholipid with hydrophilic heads and hydrophobic tails, and proteins. This arrangement of the proteins and lipids produces a selectively permeable membrane. Many kinds of molecules surround or are contained within cells, but water is perhaps the single most important molecule in any living system (Hayden and McNeil 2012). Since water molecules are so small, they are constantly going into and out of the cell. Osmosis is a situation where more water molecules are moving across the membrane in one direction than the other (Hayden and McNeil 2012). During osmosis the net movement of water molecules will be from a solution that has a lower osmotic concentration to a solution that has a higher osmotic concentration. When a solution has a higher concentration of solute within the cell than out, it is called hypertonic. When a solution has a lower concentration of solute within the cell than out, it is called hypotonic. And when there are equal concentrations inside and out of the cell, it is called isotonic. The relative osmotic concentration can be determined by a change in mass of the tissue.…

    Ectothermic animals are animals whose body temperature is affected by their surroundings. This means that if the environment is cold the animal will be cold. If the environment is warm the animal will be warm. This is because the animal doesn’t have the capability of regulating its body systems to keep a constant body temperature. When an ectothermic animal is cold, its heart rate will lower. When the animal is warmer, the heart rate will raise – as long as the temperature isn’t sufficiently high to harm the animal. (Campbell, 2005)…

    Abstract. -- The main focus in this experiment was to find out if antibiotics affect yeast cells culture when added. The observation of the two cultures along with the yield of yeast cell reproduction between the two cultures was the sole purpose of the experiment; culture-A (- antibiotic) and culture-B (+ antibiotic). Our hypothesis stated whether antibiotic effects yeast cells cultures. This theory was tested by having a chamber with quadrants that contain the culture, a hemacytometer, was used to carry out this experiment. After the data was collected from using the hemacytometer, the results of the difference between the two cultures was to be determined through a t-test. As the test was conducted, the study shows that the difference between lacking an antibiotic and containing one is not different. An antibiotic in culture-A and culture-B does not affect the number of yielded yeast cells.…

    Nowadays, climate change is one of the most natural events that has occurred throughout the world. It has led to a strong effect on many animals, by becoming a main decision of the developments of speciation or a widespread extinction. In fact, many reptiles are highly susceptible to the changed temperatures due to their physiological features which need to respond the surrounding environment to remain equally the body temperature. Additionally, there are many kinds of snakes, lizards, crocodilians, and turtles classified as cold-blooded species. Currently, global predictions and statistics calculate regularly with different locations, it will be significant to research tropical species and several sites distinctly so as to reflect upon what…
