Known pests, the house cricket, Acheta domesticus seem to have originated in Southeast Asia; they can be found in Asia, North Africa, Europe, and southern Canada, from British Columbia to Newfoundland, down to Mexico due to human introductions (Espace pour la vie n.d.). A. domesticus can be spotted in warm and moist regions of homes and buildings like fireplaces, and kitchen water heaters; They can also be found in fields, pastors and meadows, and are known agricultural pests (Zungoli 1998). They can be also be identified in moist areas like mulch, tall grass, and weeds; rocks, bricks, and wood piles are also areas where they can be spotted. A. domesticus prefer dark regions to reside (Zungoli 1998). A. domesticus’ mode of locomotion involves jumping and running (Lachenicht 2010). It is a land organism. Jumping for the A. domesticus has been possible by the the evolution of long hind limbs that use muscle contractions that can allow it to jump forward for around 17.8 cm or 10 times its body length (Lepore 2013). A. domesticus can have running speeds of around 1.3 m/s (Lepore 2013). Its jumping distance allows A. domesticus to avoid predation from animals like mice and lizards, and the running speed is important for prey capture (smaller insects) and foraging; increased performance in either of these traits has been positively correlated with better fitness (Lachenicht 2010; Bateman 2006). These locomotory traits are essential for feeding, …show more content…
domesticus will be examined through a series of experiments. It is predicted that in higher temperatures, the jumping distance and running speed of A. domesticus would be much higher than in lower temperatures because the higher metabolic efficiency allows a greater amount of energy production, which in turn boosts the muscle activity of the organism. This increases in muscle activity should allow more efficient locomotion for A.

After results, it was concluded that isopods prefer normal temperature conditions over warm conditions. We created these environments by adding water onto filter papers with the accounted for temperature measurements. The reason for the results could be seen in a usual isopod environment, it is usually dark, fresh, and moist, and the normal water temperature being the closest to that was the reason for their choosing. The Isopods seemed to locate the appropriate environment by the use of their antennas. For the investigation the normal water and warm water temperatures were independent variables. The observations were the control. The isopods behavior served as the dependent variables. The isopod behavior would be classified as movement in response to a cooler temperature environment taxis. All in all the hypothesis, “If the isopods are exposed to normal and warm temperatures then the normal temperature will be preferred” proved to be

ImageText BoxImageOne of the biggest threats to the environment of Ontario is the Gypsy Moth (Lymantria dispar dispar). The species itself is native to Europe and Asia. How this affects us is by weakening trees across Ontario and North America. The first time the gypsy moth was found in Ontario was 1969. The gypsy moth can be found in southern Canada (Ontario), New Brunswick, Nova Scotia and British Columbia. It is known to weaken trees and the caterpillar form live in trees and during most outbreaks its caterpillar feces would fall from the trees to the ground or even on top of humans. The average Gypsy Caterpillar can grow 5-6 centimeters long. With five pairs of blue spots and six pairs of bright red dots on their back. The female moth are white and can fly on the other hand, the male moth are brown and can also fly. The female have a 5cm wing span but male have a 2.5cm wing span. The gypsy moth usually lives in open forests and other forests and take up at least 20% of the space. The Gypsy moth are about 4cm long, tan coloured and can be located on tree trunks, furniture, and buildings. (OFAH Invading Species Awareness Program, 2012)
Abstract: The house cricket, Acheta domesticus, was used to test whether food and potential mates drive aggressive behavior. Male crickets were randomly selected in pairs and place into a cage to observe aggressive behaviors in the presence of no food, food, and female. The cage provided a confine area for the crickets to fight one another while the variables of food and female were used in attempts of increasing aggressive interactions between the male crickets. There was no significance found through this experiment due to a lack of data. It was discovered that the experiment would have to be done at a larger scale to be able to see any significance in the two variables.
In the following experiment, we will attempt to examine the relationship between metabolic rate and environmental temperature in both an ectoderm and an endotherm. I predict that for the ectotherm, the metabolic rate will increase as the outside environment temperature will increase. I also predict that the metabolic rate in the endotherm will remain relatively the same as the outside environment temperature changes. I also make the prediction that the ectotherm will have much lower metabolic rates than the endotherm.
Throughout time women have always been seen as the weakest of the genders, while men are seen as superior. The Cult of Domesticity was an ideology society had about women during the nineteenth century. They believed a woman was supposed to be pious, pure, submissive and domestic to be considered a true woman. Some stories that show women in this ideology are The Yellow Wall-Paper, The Storm, and The Story of an Hour. These three stories portray women living under the Cult of Domesticity or at least trying to fulfill it.
In “The Fish” by Elizabeth Bishop, the narrator attempts to understand the relationship between humans and nature and finds herself concluding that they are intertwined due to humans’ underlying need to take away from nature, whether through the act of poetic imagination or through the exploitation and contamination of nature. Bishop’s view of nature changes from one where it is an unknown, mysterious, and fearful presence that is antagonistic, to one that characterizes nature as being resilient when faced against harm and often victimized by people. Mary Oliver’s poem also titled “The Fish” offers a response to Bishop’s idea that people are harming nature, by providing another reason as to why people are harming nature, which is due to how people are unable to view nature as something that exists and goes beyond the purpose of serving human needs and offers a different interpretation of the relationship between man and nature. Oliver believes that nature serves as subsidence for humans, both physically and spiritually. Unlike Bishop who finds peace through understanding her role in nature’s plight and acceptance at the merging between the natural and human worlds, Oliver finds that through the literal act of consuming nature can she obtain a form of empowerment that allows her to become one with nature.

...e ability to climb and jump are two other traits that help this mammal survive. Its claws are hard and curved which permits it to scale the tall forest trees; its hindfoot 180 degrees so it can push off and jump incredible distances (Fischer).
The two organisms discussed I this report are humans and Frogs. The Taxonomy of an organism includes kingdom, phylum, class, order, family, genus, and species. Humans are classified by the kingdom animalia, phylum chordate, class mammalia, order primates, family hominidae, genus homo, and species homo sapiens. Frogs are classified as kingdom animalia, phylum chordate, and genus and species Rana pipens. A frogs habitat is usually spent on land for most of its adult life. However frogs reproduction and development must take place in water or in a moist place. Some adaptations frogs have that aid in their survival are having thin skin that contains mucus-secreting glands. Also they have two pairs of limbs, which can be used for swimming, jumping or walking.

Arthropods are in the kingdom Animalia which is in the subphylum Arthropoda. A species can be classified as an Arthropod if they have an exoskeleton, a coelom, and if they are mostly dioecious. An “ exoskeleton is an external skeleton made of chitin. [A] coelom is fluid filled cavity between organs and body wall” (Babin,2017). Examples of Arthropods are: spiders, ticks, millipedes, and centipedes. The objective of this experiment was to find Arthropods and test. Different habitats were established to see which will produce a greater amount of Arthropod. It was believed that the Arthropod diversity of a shaded area will be more that that of an area near a canal. The shaded area would have more arthropod diversity because more plants would be around it. Since there will be leaves and trees, plant diversity will be greater. Also, having “ plant diversity can positively affect arthropod{s}” ( Bennett and Gratton, 2013) because there will be more arthropods to utilize.
One of the first reason why insects are so successful because they possess a tough exoskeleton that is covered with a waxy water repellant layer. The exoskeleton of insects also has helped them survive. An insect's external skeleton, or exoskeleton, is made of semi-rigid plates and tubes. In insects, these plates are made of a plastic like material called chitin along with a tough protein. A waterproof wax covers the plates and prevents the insect's internal tissues from drying out. Insect exoskeletons are highly effective as a body framework, but they have two drawbacks: they cannot grow once they have formed, and like a suit of armor, they become too heavy to move when they reach a certain size. Insects overcome the first problem by periodically molting their exoskeleton and growing a larger one in its place. Insects have not evolved ways to solve the problem of increasing weight, and this is one of the reasons why insects are relatively small. But compared to animals the Exoskeletons d...
