As a conservation biologist, my aim would be to develop management strategies in order to protect species, their habitats, and ecosystems from mass extinctions and erosion of biotic interactions. I would study the loss and the restoration of biodiversity.
A landscape ecology perspective studies how landscape structure affects the abundance, distribution, and interaction of organisms. It is an approach to the study of organisms and their environment at the landscape scale focuses on broad geographic areas that include multiple ecosystems. However, the landscape structure can change through natural and ecological processes such as earthquakes, volcanoes, landslides. The human activities can also alter the landscape structure as well as improve it. Thus, the Geographic Information System becomes the best tool for research in landscape ecology. It is a tool that allows to create an interactive query; it analyzes spatial information and edit data in maps. The GIS consists of computer software that takes multiple types of data on different fields- ecology, hydrology, topography, vegetation, animal population, and human infrastructures- and combines them, layer by layer, on a common set of geographic coordinates.
For instance, a warbler can suffers poor nesting in small fragmented forest patches. In order to save the warbler species, I would emphasize the plantation of trees to make their habitat more sustainable and suitable to the organisms that will realize the different cycles necessary to the environment. I would reduce the cutting, burning, and moving of trees that will result in a severe effect within their population. By the use of the Geographic Information System, I would model a map that shows spatial arrangements of man- groves highlights the value of the assessment of the presence and dynamics of fragmented versus core mangrove forest areas. The lack of abiotic factors such as the sun will affect the biotic factors such as plants. There has to be a mutualistic relationship.
To conserve a black bear that must seasonally between mountains and lowlands, I would model maps that represent the geographical area on a planar surface whereas due to slope differences in the mountains the actual surface area is greater, the discrepancy in area calculation would lead to overestimation of population density (biotic). Also, thermal differences due to aspect affects the limits of flora and fauna distribution. There would be necessary to avoid construction on such as areas in order to make the connectivity easier.
To conserve an endemic toad that lives in upland areas but travels cross country to breed in localized pools each spring, I would model a map that shows the different climates in both areas. Since the toads are endemic, it would be better to adjust their climate by leveling the amount of carbon dioxide within the area. The toads population density will be higher in one side more than the other. By arranging the pools near the upland, the toads would not have to travel cross country and affect other organisms. Instead, they would stay in one area and make the density more stable. By the use of GIS, the watershed can be arrange in one area. Also, human activities can be reduced to diminish the amount of sulfur in the pool that might affect all organisms including toads.
