The 7 Ecosystem Functions Between Two Habitats Types

1. Make an observation – Based on the data in Table 4, discuss what patterns you observe in regards to dissolved oxygen content and fish populations in

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.

Biomes are appropriate conditions for organizing the natural world because the organisms that live in them common constellations of adaptations, particularly the climate of each of the areas and the characteristic vegetation types that develops in these divisions. It should be understood that the climate is perhaps the most important in determining classes of individuals who may live in an area and the ways they should be amended to live under different conditions of temperature and precipitation and seasonal distribution of these factors element. Every place on Earth has its own climate, influenced by both macroclimate regions as the particular microclimate. The soils are very important because they are essential to determine the types of plants that will grow into a bioclimatic zone in partical, in addition, also as substrates for animals serve. In turn, the soils are heavily influenced by regional climate, as well as the geology of the bedrock. At the same time we have to keep in mind the diversity of plants like the flora just like the diversity of the fauna as well as the adaptation of both.

Factors that may have affected the accuracy of the readings, may have been that the observations and recordings of all abiotic data was collected from one area rather than multiple sites within the area. The students involved in data collection, had no previous experience in the use of certain equipment such as the soil thermometer and refractometer, therefore, results may have varied significantly due to inadequate/improper use of equipment.

Explain how the ecosystem was affected by the missing species for each round of the demonstration.

Read "Lab 3: Biodiversity." This lab will allow you to investigate how various organisms alter their environments. Additionally, it will allow you to assess the health of ecosystems based upon their biodiversity. Then, you will utilize this information and your eScience lab kit to complete Demonstration 1 and Experiment 1 on the Week Three Lab Reporting Form. Make sure to complete all of the following items before submission:

Name and describe the roles of the three main trophic categories that make up the biotic structure of every ecosystem. Give examples of organisms from each category.

larger vegetation zones to the way we should understand the ecology of the land scape.

In 1995 the gray wolf (Canis lupus) was reintroduced into Yellowstone National Park. The park had been without resident wolves for 70 years prior, when they were killed off in the 1930’s. This meant that in those 70 years there was no research on the effects of wolves on the park’s ecosystem. In the decades since the reintroduction, research has been able to proceed and has found some amazing results. Not only did the reintroduction of wolves impact animal life, but it also had an impact on plant life. “In the past it was thought that an ecosystem was built from the bottom up... with plant life as the basis from which everything grew. Almost all conservation and reintroduction efforts were based on this idea.” (Mission: Wolf Education vs Extinction)

In Area 2, the species with the highest dominance value was the Oregon White Oak (70.6%). Oregon White Oaks provide shelter, housing, and food to various animals as well. Diversity of birds is often higher in Oregon White Oaks than in an adjacent coniferous forest. Using the dominance data, it tells us that at this moment in time Oregon Oak and

Specifically, in this analysis method, water consumption, ECEC (Ecological Cumulative Exergy Consumption), carbon and nitrogen mobilization,

Class input data into excel and a class mean and standard deviation was gathered from both wetlands for each species. Excel was used to produce the mean and standard deviation for all data, then graphed for ease of interpretation.

Recent studies focused on biodiversity have begun to include the concept of functional diversity, which measures the range, value, and distribution of functional traits of organisms in a community ecosystem (Tilman et al. 1997; Mouchet et al. 2010). It is becoming increasingly accepted that biodiversity components of plant community, i.e. the species identity, abundance and divergence of functional traits, strongly affect ecosystem productivity, functioning, litter decomposition and soil nutrients dynamics (Wardle et al. 2004, 2012; Naeem & Wright 2003; Díaz et al. 2004; Hooper et al. 2005; Mouillot et al. 2005; Cortez et al. 2007; De Deyn et al. 2008).

to determine differences (if any) in densities of native and non-native birds relative to the type of vegetation present. Two native vegetation areas and two non-native vegetation areas were studied (i.e. four areas in total).
