Abs 270 Final Exam Answers

B. Retaining individual high value trees--for bear dens, raptor nests or as an example of old growth

Describe the major developments, changes, and the general living patterns of the Great Lake Indians during the period from 1000 BC and AD 1600. Make sure to provide at least 3 different components for each of the main timeframes outlined in the readings (Early Woodland, Middle Woodland/Hopewell, Late Woodland, Mississippian/Upper Mississippian).

The purpose of this experiment is to observe secondary succession at Umass Dartmouth and test the prediction that diversity increases through ecological succession. Students went outside to the lawn underneath the wind mill on campus. 3 transect sites were located by the instructor. Students predicted the species and percent cover of each species on each trail site. Bar charts were made to compare the number of species in each transect. Pi-charts were made to compare the percent coverage of species in each transect.

2. Predict: How do you think the amount of land available will affect the rabbit population?

1. How did the Huron view of nature affect their treatment of the environment—including animals, trees, and plants?

2. Describe what you can see within your community that shows physical diversity? Provide at least three different examples. [1.2]

Describe the major geographic regions of Arkansas. (geological development) times and dates, and discuss what these differences meant in the development of the region.

5 Factors that might cause fluctuations in the amount of vegetation in a area and how this impacts the animals that eat the vegetation.

The common traits that all four land areas expressed on the survivorship curve were between type one, two and three. Most of the species found in the vegetable block, grazed and ungrazed pastures such as Vulpia are R selected. R selected are short lived, highly mobile, often density-independent and the survivorship is typically lower than K selected species (Parry, 1981). R selected are typically more frequent than K selected but are also unstable. The woodlot and some species in the ungrazed pasture are K selected species, such as Blackberry. These species are typically long lived, the mobility is often more sedentary, often density-dependent and the survivorship is typically medium to high (Parry, 1981). Shorter lived plants are

When people think of the American Prairie, they think of a dull, and grassy-full biome. But, the American Prairie is an extremely fascinating biome. At first glance, this grassy biome may look really dull and boring, but if you look deeper into it and feel nature playing its daily roles in this prairie around you, then you will see how unique this biome is.

Grasslands are characterized as lands dominated by grasses rather than large shrubs or trees. There are two main types of grasslands: temperate grasslands and savannah grasslands ("Types of Biomes", 2017). One major savanna grassland is located in Africa and takes up more than a third of the continent's land area. Others can be found in India, South America and Australia. If the grassland is prevented from developing into a forest by climatic conditions such as rainfall, it is termed as ‘climatic savannas’. If their characteristics are kept by soils, they are termed as ‘edaphic savannas’. These can occur on hills or ridges where the soil is shallow, or in valleys where clay soils become waterlogged in wet weather. Human activities such as farming

1. Investigate the characteristics of its wild (ancestral) counterpart. What characteristics allowed the wild counterpart to survive in its natural habitat?

Explain how environmental factors (temperature, water availability, soils and topography) influence the yield of the food staple.

In 1988, a series of fires burned much of Yellowstone National Park (Klotzbach, Thayn 2014). Satellite images were used to measure light reflection, which were used to represent the growth and health of the trees after the fires (Klotzbach, Thayn, 2014). Lodgepole Pine, (Pinus contorta), was one of the species focused on since it is found in about 80% of the park (Turner et all, 1999). Satellite images were taken in late summer to early fall, on cloudless days (Klotzbach, Thayn, 2014). In areas that were only lightly burned, percentage coverage of Lodgepole pine returned to normal, before the fires, in 1991 (Turner et all, 1999). The seed density after the fires varied based on fire severity, areas with severe surface burns had little seed distribution at first, but increased substantially in 1990 (Turner et all, 1999). Areas that had
