promote gene flow. The eastern lineage stayed in the eastern United States. The western lineage stayed in in the western United States. Since the eastern and western lineages seem to overlap the Canadian Prairies seem to offer a bridge of riparian habitat where they can meet the glacier retreat. The gene flow seems to be more important along the North-South axis of migration, suggesting that spring migration play’s a big role in the dispersal of lineage. In North America the yellow warblers…

The Effects of Limiting Factors on Seahorse Population There are over 50 different species of seahorses, yet they all have very similar characteristics. They all have the same relative shape, size, food source, and habitat. However, there are certain limiting factors with which each unique population must deal. Limiting factors affect the population size and density of seahorses, but also keeps them in check. Seahorses are small animals that live in the tropical or temperate coastal waters of…

experiment was how does the sow bug’s preference of habitat affect the concentration and distribution of the organisms. The purpose of this investigation was to decipher what habitats these organisms prefer to live in and how it would affect their population density. This was tested by a simple experimental design with four petri dishes that each represented a different environment. The control treatment was the dish with just dirt while the other habitats included rocks, wood, then dead leaves.…

According to DeGraaf & Yamasaki, green heron’s habitats are found in a variety of freshwater and saltwater habitats that are primarily shrub or forested wetlands. They are also found in brushy areas that are margins of slow-moving rivers, lakes, and ponds. Frequently inhabits marshes, beaver’s ponds, salt marshes, mudflats, harbors, and human-created canals and ditches. To feed, they have to be near wooded wetlands near shallow bodies for feeding. These waters should be abundant in small fishes,…

There are two main reasons for this, hunting and habitat destruction. The Komodo dragon is an apex predator in its environment, meaning that in its environment the Komodo dragon is the top of the food chain. There are no other animals that predate it. Removing an apex predator from an environment causes…

of the world's most endangered species, that unique and rarely exist in China. The Earthquake that took place in 2008 Wenchuan, China, cause of huge damage to the ecosystem, which breaks down the environment that Panda live in and harm the living habitat of the panda. On May 12, 2018, an 8.0 degree earthquake took place in Wenchuan, China. The quake damage thousands of lives. Through the earthquake, almost 375,000 people were injured, (CNN, 2009) The quake damage huge amount of lives, and it…

commonly known as the lesser snow goose, have increased significantly. Loss of suitable habitat for nesting is causing waterfowl to migrate toward the poles. This is a concern among ecologists and population biologists because more species will be migrating to more northern areas and affecting the habitat. The tundra is already being degraded because of over population of ducks and geese in response to these habitat changes. Increased survival rates during the winter and spring migrations will…

As a landowner, it is important to manage invasive plants in order to preserve our native habitat; to care for our fields, forests and waterways; and protect farmlands. Controlling the spread of invasives can be a complicated issue, because complete eradication is unrealistic in most cases. Managing the most common invasive plants, different control techniques, and tips for preventing new invasions from occurring can help to stop the spread of such plant species. Non-native invasive plants…

The explosion of the Deepwater Horizon that occurred in April of 2010 greatly affected the wildlife and habitats that surrounded the northern Gulf. As a result of the oil spill, the impacts it faced on wildlife such as dolphins, whales, sea turtles, fish, birds, and even the Gulf’s floor is detrimental. The article, “The Deepwater Horizon's Impact on Gulf Wildlife and Habitats”, explains the affect the oil spill had on all the wildlife as well as provides links to allow the reader to support and…

deterministic in nature. Throughout my education in aquatic biology and ichthyology I have begun to realize that that the natural world is relatively predictable. Throughout my academic career I have heard multiple professors say that if you know that habitat of a location then you can make relatively…
