Analysis of Sow Bug Behavior in Selective Environments Abstract The purpose of this lab was to observe the behavior of sow bugs in different environments when given a choice of two different environments to be in. The observations were conducted through two different experiments. In the first experiment we observed the sow bugs preference of environment between a dirt environment and a sand environment. This was done by placing the sow bugs in an environment that featured isolated areas of sand and dirt in equally divided sections and recording what section they were positioned in every minute for 5 minutes. It was observed that the sow bugs spent more time in dirt environment than in the sand environment because the sow bugs had more recorded positions in the dirt environment.
As stated before, Townsend moles were found most out of the 11 species discovered in the lab. Being the most, one may be able to determine that owls prey on them the most out of the others, and the owl preys the least on the Coast moles and Creeping moles (because they were preyed on the least according to the information). This information could however be misleading at the same time. Despite the facts being presented in the lab, it’s only a small experiment. If a larger scaled experiment was held, results could differ tremendously.
Abstract Constructing a cladogram to determine the related species and the evolutionary history. Five mammalian species, which are dog, cat, horse, opossum, and deer, are distributed into cladogram based on morphological character and molecular data. This allows identifying the relatedness of these species. By their appearances of structures and behaviors, the dog and cat eat meet while deer and horse eat plants. This prediction leads to the hypothesis that car and dog are close whereas deer and horse are related.
Abstract: In this study of researching animals and their behaviors, demonstrates the behaviors of sow bugs and their likeness to dry vs. moist and light vs. shade preference. The general hypothesis for this experiment was that the sow bugs would prefer the shade vs. the light, and the moist climate vs. the dry climate. In this experiment, six sow bugs were obtained in a petri dish lined with filter paper that was taped to keep the bugs from escaping. Three different trials were completed by first covering half the petri dish with a piece of construction paper and the other half left uncovered in the presence of light. The second trial completed was covering half the filter paper with drops of water to present moisture, and dry on the other half, both in the presence of light.
The diamondback rattlesnake’s skin is also another example of how this organism has adapted to living in the Southwestern desert. The diamondback’s skin is made up of a protein called keratin which is largely found in human hair and fingernails (Busch Gardens, 2002). This barrier helps reduce the amount of water that is evaporated through the snake’s skin. This is extremely important to an animal that lives in an environment as desolate as the Southwestern United
Vulpes zerda of the Saharan Desert Leanne Cubar Gessica Davila Biology 211 Professor Mustard November 18, 2013 Within the Sahara and other sandy deserts of the North African continent, a small carnivorous fox survives and thrives in scorching high temperatures as well as the freezing desert nights. Vulpes zerda, commonly known as the fennec fox, usually lives in small communities consisting of about ten other individual foxes where they utilize physiological and behavioral adaptations to combat the constant challenges the Sahara presents. Alongside the fluctuating temperatures, another challenge includes the scarcity of water and food. iOne may wonder how animals such as Vulpes zerda survive in such an extreme environment, and the
This insect has a fossil record dating back as far as the Cretaceous period, 140 million years ago and have developed into approximately 2600 different species around the globe, most species inhabiting tropical rain forests and the savannas; fewer inhabiting more temperate climates. They are detrivores and are a very important part of any ecosystem, eating and breaking down dead plant and tree debris, wood and wood in soil, returning fertilized product back to the earth because of this process. Termites are divided mainly into two groups: either cellulose digestion in their gut using protozoans (lower order) or by cellulose digestion via the use of fungi (higher order). These relationships are called mutually symbiotic due to both the termite and the protozoan/fungi both benefitting from the role each other plays in this relationship. The four types
In Arizona, the fence has contributed to flooding on both sides of the border, changed the roaming patterns of the area’s native jaguars and destroyed the desert habitats of several bird species, including an endangered quail, according to environmentalists. The building of patrol roads has also decreased the Sonoran pronghorn’s habitat, as the antelope like animal rarely crosses roads, according to a 2006 report from Defenders of Wildlife. The pronghorn’s limited jumping ability also does not allow it to leap over barriers. Altogether, Brian Nowicki, a Center for Biological Diversity conservation biologist says, “30 endangered, threatened, or candidate species live along the U.S.-Mexican border in Arizona and Sonora, 15 in the area where the wall would be built. Moreover, building a wall, along with the roads and support facilities it necessitates, would not only plow under saguaros and other fragile desert plants but scare Sonoran pronghorn and other wildlife from important sources of food and water” (Cohn
A)Some protected species are illegaly killes for their valuable parts or are sold to live collectors. Brings about $600,000 per hour. Mountain Gorilla, White Rhino, Komodo Dragon. Q)Why are wild tigers likely to disapear within a few decades? A)Because there are only between 3400 to 5100 adult tigers roaming free.
In my experience when I lived in Arizona for 7 months comparing where I live now in Florida “The Sunshine State” both states are completely different when we start talking about their weather, scenery, cost of living or culture. Because both states have a lot of resources but they still different in the topics I just mentioned. Talking about the scenery in Arizona they have a very dry and red scenery with a lot of red rocks mountains where you can do hiking, find a lot of different animals like scorpions, rattle snakes, coral snakes, mountain lions, and wolves all these animals are natural from the Arizona environment. In Arizona you need to drive up to 6 or 8 hours just to find a beach in California. In Florida we have a green scenery flat no mountains but is completely different than Arizona, here you can find a beach
