    Purpose The purpose of this lab is to investigate animal behaviors by diving into the world of ethology. There are two ways pill bugs will respond to environmental stimuli: Kinesis (non-directional response) and taxis (directional response). Kinesis occurs when organisms (randomly) move around quickly when they’re unhappy and slowly when they’re happy, which is best demonstrated when one lifts up a rock or other material that the pill bugs are under. In contrast to the simpler response that does not necessarily involve many neurons, taxis is often observed in response to changes in light, heat, moisture, sound, and/or chemicals (odor).…

    Being a TCU horned frog feels right for many reasons. TCU affords me the opportunity to move away from my hometown, Waco, it allows me to select from any of the majors I've considered; it provides me all of the resources I need to learn and excel; and it means I get to cheer on one of the best football teams in the nation, all while being in a faith-growing environment.

    The cane toad is an opportunistic predator in which they take advantage of any vulnerable prey. They are omnivores feeding on either plants or animals, both invertebrates and vertebrates, with their diet consisting of small insects like beetles, spiders, termites and ants as well as small snakes, mammals, birds, and household scraps (Department of Environment and Primary Industries, 2014). The invasion of the cane toad has been successful due to the few natural and carnivorous predators which can tolerate the species ability to breed quickly, voracious appetite and poisonous characteristics (Shine R. , 2006). Their omnivorous approach are features of species on a typical 3rd trophic level and are generally predated by carnivores. This can be seen in the Figure 2.1 which breaks down the location of producers, herbivores, omnivores and carnivores in a typical food web.…

    Discussion Our results supported the alternate hypothesis that Atrazine affects the geotactic movement of Daphnia (Table 1). The pesticide we used disrupted the natural behaviors of Daphnia, and thus affected their performance. These results were expected since Atrazine is a powerful weed –killer that have the abilities to disrupt the nervous system in human and animals, this is why the Daphnia displayed a vertical movement when they placed in the Atrazine solution, which was an attempt to avoid it.
