Fish on Prozac: Investigating the Mechanisms of Aggressive Behavior in Betta Splendens October 24‚ 2013 By: Michael Min Lab Partners: Jay Hwang‚ Josh King‚ Jesse Jung Lecture Professor: Dr. Norskov Introduction Betta splendens‚ or Siamese fighting fish‚ have been previously used to study the affects of selective serotonin reuptake inhibitors (SSRI) on aggression levels. Specifically‚ the SSRI used in most studies is Fluoxetine‚ which can be

The purpose of having a control when doing a lab is because it is the part that is already known and not likely to change. It is always important to have a stable variable in any experiment you do. This also helps with overlooking hidden variables so you can compare how the organisms in the control behaved differently from those in the experimental situation. The purpose of having multiple variables is to compare the difference between the outcomes with each of the different variables. It is important

mechanism used by fish in freshwater and marine environments. Although used rather loosely in conjunction with the term “schooling‚” the two words differ in definition by nature of organization. Where shoaling refers to a congregation of conspecific fish that stay together‚ schooling indicates that those fish are swimming in a coordinated fashion. Shoaling is not a learned behavior‚ but one in which a species is born to participate. This conduct evolved in as many as 50% of all fish species for a number

Betta value stores meeting report: The first issue in the meeting that we discussed was that at the store enterance‚ there are too few shopping baskets‚ and any available trolleys are of the wrong type. The store has problems with persuading shoppers to return them to the trolley park at the main entrance of the store. We had quite a debate on this issue as Zara and Ahmed had quite strong ideas. Ahmed had the idea of nectar points and that every time you put your trolley back you will get points

terrestrial‚ seek to avoid stressful thermal environments or to compensate for the temperature change by mostly lowering the metabolic rate (1979). Lowering the metabolic rate allows certain enzymes to be produced and chemical reactions to happen within the fish that actually warms it up. While lowering metabolic rates are important‚ respiration regulation is also important. Stephen C. Wood also believes that ectotherms need behavioral mechanisms for temperature control. These mechanisms could include slowing

species and origin based on morphological features by using DNA barcoding technique is an important application for molecular biology and genetics. In this study‚ we used special fish called bonito fish. These fishes generally live in relatively warm and hot seas and grow until they reach a length of about 30 inches. Bonito fish have a long pectoral fin and two dorsal fins. Also‚ they have a forked tail. Animal species and their origins can be detected accurately and quickly with the help of the technique

Treatment diets included the basal diet‚ or the basal diet with 0.05% Macrogard (D0.05)‚ 0.10% Macrogard (D0.10) and 0.20% Macrogard (D0.20) supplementation. Data are presented as the means ± SEM. Different letters are significantly different between treatments at each time point. Table 4. Growth performance of pompano fish fed different concentration β-glucan in the diet for 28 days. Data

The Agonistic Behavior of Betta splendens. Abstract: Animals are constantly display agonistic behavior to speed along the process of natural selection. To truly understand the mechanics of agonistic behavior‚ the causes and various stimuli that encourage agonistic behavior must be studied. This research investigated three Betta splendens and their response to various stimuli in order to depict whether or not they reacted most strongly against each other. It was found that to a minimal degree

I. Title Laboratory 11. Animal Behavior II. Purpose The purpose of the animal behavior lab was to understand the concept of distributing organisms in a resource gradient. This lab was also made to help us differentiate between kinesis and taxis. After completing the animal behavior lab‚ we should be able to describe aspects of animal behavior as far as its orientation behavior‚ agonistic behavior‚ dominance display‚ and the way it mates or who it chooses to mate with. We should also understand

in Australia‚ as "white ants"‚ they are only distantly related to the ants. A pheromone is any chemical substance released by an animal that serves to influence the behavior of other members of the same species. Furthermore‚ the pheromones are chemicals capable of acting outside the body of the secreting individual to impact the behavior of the receiving individual. Thus‚ the researcher did an experiment to see whether or not the writing utensils have a pheromone that attracts termites. hen termites
