Determining the affects of natural selection on gall fly (Eurosta) larvae from different predators Ariel O’Neil Biology 1020H Abstract This lab was done with the objective of determining if directional selection causes early larvae death in the gall fly. By first examining the parasitoid wasp and birds predatory actions we can hypothesize and predict the smaller galls will be most likely to survive directional selection. To figure out if this is true or not a large variety of goldenrod galls…

Canada accounts for roughly 7% of the forests in the world. This implies that Canada has an important role to manage their forests effectively. As we know, there are many factors that can disrupt the forest system, the two major groups of threats are seemed to be the natural disturbances and human activities. In terms of the human activities, such as farming and industrial development, are thought to be responsible for disrupting the forests. It is considered as rather a smaller effect in the…

process however both have different adaptations that allow them to live in either land or water. A diving beetle and a mayfly are both good examples of how insects have adaptations that allow them to live in the water and be fully submerged without drowning. Diving beetles swim to the surface of the water to collect air, the gas exchange process then occurs and oxygen is produced. When the beetle swims back under the water they have a system in which they conceal the oxygen in…

sister, who would turn on him later in the story. Upon metamorphosis, Gregor could no longer provide for himself, which wasn't a problem, or his family who, he was most worried about. From the point of this major physical change from a human to a beetle, his family starts to turn on him. This is due to the fact that Gregor had no longer acquired the ability to work to work and provide for his family. After everything he had done for his family, it seemed to hold no meaning to them. They were…

Have you ever seen water come up storm drains in sunny weather in the middle of the day? Or how about 70,000,000 people being stranded on rooftops? This is a problem people are beginning to face every year because of climate change. Climate change is greenhouse gases trapped in the atmosphere, causing earth’s temperature to rise. Climate change is a huge issue because it causes many problems that destroy lands and waters, and kill animals, plants, and humans or cause them to relocate. It is so…

not as helpful though. They still eat aphids but they are considered an invasive species. This type of ladybug is called an asian lady beetle. The asian lady beetle is an invasive species. The asian lady beetle is in the coccinellidae family just like the ladybug. They also have the same color and almost the same pattern as the common ladybug. Asian lady beetles are commonly considered a nuisance pest. They are very aggressive.…

In any plant or crop you are going to have to deal with the common diseases and insects that go along with it. A few common diseases of corn are: Stewart’s Bacterial Wilt, Root Rot, Corn Smut, and Southern Corn Leaf Blight. Stewart's Bacterial Wilt is a disease that affects corn at any stage of the growing period. Although, this particular wilt is most harmful when sweet corn is at a very young stage. This disease causes wilting and dwarfing of the plants and the plant will most likely never…

microbial waste. Dung Beetles, play an important role in agriculture. They digest manure, which they use as a source of nutrition, which improves nutrient cycling, soil structure and forage growth in cattle feeding areas (Yoshihara and Sato, 2015). Beetles, such as Chauliognathus pennsylvanicus, also play a vital part in pollination. They feed on aphids and act as a pest control which reduces the usage of insecticides but promotes pollination due to the increased movement of the beetles from…

America’s trees and forests has emerged in the form of two invasive species of beetles, the Asian Longhorned Beetle and the Emerald Ash Borer. Both beetles are major pests of widespread forest and neighborhood trees, and if left unchecked, have the potential to completely change the character of our forests. Although not as widely known as some higher-profile environmental issues, invasive species like the Asian Longhorned Beetle and the Emerald Ash Borer are nevertheless one of the greatest…

The Beauty of Complete Metamorphosis It was a warm day in early October. A young boy at the age of 11 with pale skin and freckles was frolicking in his neighborhood park about a block away from his house. He wore his favorite pair of blue jean overalls with a yellow and olive striped shirt underneath. He loved being outside and spent most of his time at his neighborhood park. His normal routine after he got off the bus from school was to go home, eat a snack of some sort, change into his play…
