Comparison Between Community A And Community B

820 Words4 Pages

On October 6, 2016, our environmental science class explored biodiversity. We conducted a lab involving the biodiversity of cars in two parking lots that are at our school. We used the parking lots as "communities" and the make of each car in a specific parking lot a "species". We classified the parking lots into Community A and Community B. Community A represented the athletic parking lot and Community B represented the band parking lot, both lots hold students and factuality cars. Our class split in half, one group attained data for Community A while the other attained data for Community B. We acquired our data by counting and writing down the make of each car in the parking lot. After this each group tallied the same "species" together …show more content…

Then the groups used the data from each community to find the species richness, evenness, dominance, relative diversity, and the Shannon-Weiner Index for of that particular community. The diversity measurement table shows the reader the comparison between Community A and Community B. In Community A there were 49 different species and in Community B there were 40 different species. The groups configured this information by plugging in the data from each community into the equations, H= -sum(Pi In [Pi]) and E= H/In(R). (H) being the uncertainty of predicting a species, (Pi) being the relative abundance, (E) being the evenness, and (R) being the species richness. By the results of equation we could determine the evenness, relative diversity, and the Shannon-Weiner Index of each community. The species richness is how many species there are in a certain community, it does not mean how many individuals there are. The evenness of community is calculated with the equation E= H/In(R). The dominance of the community is based upon which species had a higher population than the rest. The relative diversity is based off of the Shannon-Weiner Index, if the answer is less than or equal to 3.2 it is a low diversity and if it is higher it is a high diversity. The Shannon-Weiner Index is calculated with the equation H= …show more content…

Community B has the fewer amount of species and number of individuals in its population between the two communities. The result of a lower population of species could be because of pollutants produced by humans. This could have harmed the environment in which the species lived, so much, not a large amount of species can adapt/live there. Also, the humans could have destroyed habitats and homes of the species that the species can no longer live there because they have no shelter. Humans can destroy habitats by deforestation, construction,

Graph 1: H-Value averages The data in this graph is calculated by using the Shannon-Weaver formula to determine the diversity of species on A-mountain. H-values were averaged from the transect data recorded according to Table 1 and Table 2 on both sides of the mountains. The closer H is to 1, the higher the diversity in the area. The closer H is to 0, the lower the diversity in the area.

Biotic components of ecosystems include plants, animals, and fungi living in that ecosystem that interact with the environment and other abiotic and biotic components. 8. Create a chart of the major characteristics of and differences between the following terrestrial biomes: Tundra, taiga, grasslands, temperate deciduous forest, desert, monsoon rainforest, tropical rainforest. 9. Create a chart of the major characteristics of and differences between the following aquatic biomes: freshwater ecosystems such as lakes, wetlands, and streams, marine biomes such as estuaries, intertidal zone, neritic zone, open sea zone, and deep sea zone.

For this field excursion the coastal prairies and dune communities of the BML were explored. Community composition and interactions in these areas were areas of emphasis on the excursion, as well as morphological adaptations organisms use to survive in these landscapes. These coastal environments can be a harsh place for species to make a living. Factors such as solar radiation, desiccation, sand showering, coastal winds, nutrient deficient soil, invasive species, and structural instability are all factors species in these areas have to cope with. However, despite these challenges these communities have found a way to thrive and are teeming with life.

The growing human population plays a great role in extinction today and hundreds of years ago. Colonization is followed by an “extinction pattern” that has drove species to go extinct. As the population increases, there was a need to “plow wildlife habitats, divert streams, and maintain large herds of domestic cattle” which force species to move away from their homes and become extinct (Center for Biological Diversity). I can understand how human colonization has displaced species and altered the survival success for these animals who were present 1000 years ago now extinct. Human population led to the drastic effects on the environment resources which cause many species and plants to go extinct.

To begin our experiment we created a food web. We created our food web by identifying what organisms were producers or consumer. If the animals were consumers, then we further grouped them into one of three categories: primary, secondary, or tertiary/apex. We did this to make it easier to later arrange them on the food web and find what it should eat. We started with producers.

My community placement is at Brampton Caledon Community Living. The community is mostly for adults and people with intellectual and physical disabilities. It works to support and empower all people in the area and it works alongside the community and families in the community. Most of the people that attend the program are adults that live with either their parent(s) or a family member (low income) in Bolton. To help reach out to and accommodate to families with lower income, the center charges a small fee for the adult to attend.

However, the rate at which the species were discovered became less and less. This correlates with the Species Area Relationship (SAR) theory as proposed by Arrhenius. When graphed, in both plots we notice a curve. This to correlates within the SAR theory in a small area. As we did not analyze a large area, which encompassed multiple biomes, we did not find the “s” shape graph, which is evident in figure 1 in the literature review.

Another problem is that animals lose their habitat. Mostly, animals need a minimal amount of space, where they can hunt, breed and expand their population. Only one bird can be comfortable with a branch of a tree, although large mammals (like Bengal tigers) need a lot more space. As human civilization expands, these natural habitats diminish - and their restricted

In addition to survival, one of the biggest differences between people and other species is that humans can cause absolute demolition to areas for the sake of comfort or success. An example would be deforestation, where people would destroy forests, which are the habitats and sources of food for various animals, to build more factories or buildings that already

Community, in a broad sense, is a tremendous part of what makes humans tick. It can help us stay mentally and physically healthy. Few can doubt how important community is, but it is a vague concept. Trying to define community is as difficult as defining literacy but both are important concepts we strive to understand. One underlying theme I see in literacies is that people use them to find their place in the world.

This concept of the Island biogeography theory describes how the number of species on an island , increases as the island size increases (Pâslaru, 2014). Another concept of the Island Biogeography Theory is the species – isolation relationship. This describes how the number of species decreases as the distance between the island and the source increases. The distances from the source have an influence on the movement of species to the island (Pâslaru, 2014). The Island Biogeography Theory takes into consideration the immigration and extinction rate of species.

In honors biology, we watched a film called Racing Extinction. In this film, we learned that humans are the main reason that species of plants and animals all over the Earth are becoming extinct at a rapidly fast speed. The men in the film showed statistics and images that were mind blowing, that I had absolutely no idea about. Humans are more destructive than we think, and we need to do something about it before it is too late. When most people think of the word “extinct”, they relate it to animals, instead of plants.

A community, a complex term that often times elicits various feelings and definitions, generally implies that there are relationships between a group of people that share some common goals, values, the same geographical location, or, perhaps a way of life that reinforces one another. In a community, members choose to associate with, or connect to each other. However, it is only when we take a step back from the activities in our life’s, do we recognize reality and witness the social interactions that occur around us every day. The overarching purpose of this assignment was to go out into the community on two separate occasions to observe the social interactions- paying close attention to evidence of social networks, excluded or exclusive communities,

Hence, deforestation increases. This is another effect of overpopulation that impacts the worsening of the environment [2]. For example decreased forest size increases the amount of carbon in the environment. More specifically, deforestation affects the wildlife and results in biodiversity loss and species extinction [1].
