Title:
The difference in bird communities using climate as a factor in two differing habitats.

Introduction:
Bird communities are highly vulnerable to changes in climate as a variable. The factor of habitat type is also very important in determining the abundance and diversity of bird communities. Habitat features, elevation and variation in climates is seen to been ecologically important, as these particular three factors in differing combinations create diverse bird communities. Varying climates can cause many changes in bird reproductive cycles, migration patterns and behaviours. Birds are endothermic vertebrate creatures that have a very extreme variety of diversity within the concept of the generalized bird organism. This directly correlates with the fact that differing bird types live and survive in fluctuating climate changes and habitat environments. Temperature and precipitation (rainfall mm) changes are seen to clearly affect bird species in their environment, and these features can be seen to cause disturbances from unsteady weather patterns causing storming, flooding or fires. Climate changes can also cause the introduction of new predators and competitors, causing changes in bird species abundances.
This particular study was facilitated in Chihuahuan Desert of New Mexico, United States of America. This region is in a desert setting and was specifically set in the Sevilleta National Wildlife Refuge. It is known to be a large breeding and nesting site. The two habitats in this study were the mixed grassland and pinyon-juniper woodland. The mixed grassland habitat contains no elevation and has an array of desert grassland plantation. The pinyon-juniper woodland region is an elevated space with areas of open savannas to other areas of closed forest. The study was necessary to determine the actual effect of climate on bird communities within two separate habitat environments. This is done by

    A small population of finches have been discovered on Darwin and Wallace Island. The population is 200 finches at Darwin Island, and 200 finches at Wallace Island. The year is 1997, and scientist measured the finch beak size from both Darwin and Wallace Island. The finches from both island, showed an average beak size of 12.0 mm. Precipitation on both Darwin and Wallace island average 20.0 cm. Scientists want to determine if precipitation was to increase, would the finch beak increase in size? In this lab study, scientist will be measuring the amount of precipitation within the discovery of the finch on Darwin and Wallace island, and collect data to prove that the finches evolved a larger beak due to the increase of rainfall.…

    1. There are many ecological and biological factors that affect evolution. In EvolutionLab, two populations of finches are tracked over the course of 300 years on two different islands to see how changing the traits of the birds and their environment affect their long term viability as a sustainable population. Let’s begin by doing a “null experiment” where conditions are identical on the two islands.…

    Evolution is a natural process in which animals adapt to their surroundings so that they may survive. There are many variables in an animal’s environment that influence its evolution. The purpose of this lab is to examine finches from the island of Darwin and the island of Wallace and how the island size, finches’ clutch size and the precipitation on both islands directly affect the finches’ beak size and population. I believe that a larger island size, larger clutch size and high precipitation will lead to a smaller beak size and larger population.…

    Biologists over the years have observed that some species evolve in response to the changes in another. These changes can occur in different levels and in different intensities. Some species exhibit molecular changes such as the structures of macromolecules like proteins or lipids, while others show morphological and behavioural changes in the presence of other organisms. Some evolutionary changes that happen in a species can be a change that is most especially directed towards its adaptation in its relationship with another organism. This evolution that happens in response to the changes in the biotic factors of the ecosystem is called co-evolution. The habits or changes in one organism in an ecological relationship create a pressure that drives changes to another. Therefore, evolutionary changes in organisms due to changes in temperature, water and other abiotic factors are not co-evolution, even if changes happen simultaneously in organisms that are in a specific ecological relationship.…

    It shoes the changes in biodiversity of regions unaffected by human development and the monitoring stations are permanent. Support is also form the public and the government, not a private corporation, therefore the results of the studies are less likely to be biased to support the corporation. The most accessible data is about piping plovers, winter waterfowl, and, Nantucket Lepidoptera, although there is more data on the website. The piping plovers had about 30 pairs on the studied areas, and despite efforts, the population decreased slightly, but have rebounded slightly toward the carrying capacity of 30 pairs. Conservation efforts include fencing in the area where they lay their eggs on the beach and trying to help them during the oil spills that affected the area. Winter waterfowl are surveyed and the data is processed comparing the number of waterfowls to the ice coverage in the different months. The conservation effort is limited for the waterfowls, due to the limited amount the Center can do about ice in the area, which is a limiting factor of the waterfowl population. The Nantucket Lepidoptera has been monitored due to the amount of endangered sub-species it…

    Finches reside on two islands, Darwin and Wallace. Parameters for one island will be changed to study the evolution of the finch’s beak size and population. This experiment will show basic principles of evolution by examining the finches over a time frame of 100 years. The purpose of this experiment is to understand factor that effect evolution of a species and biological and environmental factors that influence evolution by natural selection. Hypothesis- If the same species of finches populate a larger island (Darwin), then they will reproduce more and have better survival rates than a small, restricted island (Wallace).…

    The Barn Swallow is the most widespread species of swallows with their profound coloration somewhat resembling their sophisticated melodies. With the NABPP offering maps, I was able to determine the specific migrational patterns of Barn Swallows. These birds reside in the North American region and migrate to South American locations during the winter times of the North. The birds migrate due to the changing climates due to season changes. When winter time in the Northern hemisphere, the birds migrate to the Southern Hemisphere being that it is warmer and summer time, the same rules apply when it is winter in the Southern Hemisphere. Barn Swallows find areas such as marshes and damp locations suitable. They use resources made available to them such as mud, sticks, and grass. Locations with a moist atmosphere encourage breeding among the birds and the population soon begins to grow. With the help of the volunteer observers, I was able to analysis the maps with the collected data. Analyzing the maps of each decade starting at the year 1860s, I came to the conclusion that both the migrational patterns and the population status of these birds were altered. The patterns changed every decade yet they stayed in the same region. This large region in North America included states and territories that had large bodies of water and tend to have quite warm summers. These areas…

The observation took place at a local park in Pasadena that Sky frequents quite regularly for play time. We arrived at the park at approximately nine fifty in the morning and left the park at ten thirty. The park is about five acres and located in a quiet neighborhood of Pasadena, CA. It has a playground, basketball courts, handball courts, and plenty of open grass and trees which make for a calm and peaceful setting. The park was fairly empty with a few adults engaging in morning fitness activities, and the playground was empty. The temperature outside was about ninety…

    The changes in land use and decreased wetland access for migrating fowl may lead to larger fowl densities, flock, stress, and closer proximity to domesticated flocks. It is also suggested that the climate such as changes in temperature or increased areas suffering from drought may have an impact. Migrating fowl tend to congregate where here is more water. Another impact on the environment is the increased consumption of chicken which has tripled between 1960 and 2002 (Vandegrift, 2010). With a higher demand for poultry production, farmers have increased the number of birds on their farms. With a larger poultry population in a smaller area, there is an increased potential for easier transmission between flocks and the possibility of the virus becoming an…
