Allochthonous Deciduous Lab Report

On September 17th, 2015 our group went on the Orange Trail of the State Botanical Garden of Georgia in Athens, Georgia to collect data for our lab. The biome of this area that we explored fit a temperate deciduous forest type. We walked along the trail and picked random spots to start measuring our transects. We measured DBH size and canopy coverage at 10, 20, 30, and 40 meters respectively along each transect for a total of six transects. We used a densitometer to measure the percent of canopy coverage of the tree closest to the center of the sampling points along each of the transects. We used a measuring tape to measure out 10, 20, 30, and 40 meters respectively along each of the six

Through our research we aimed to determine if there were any differences in water quality of both the north and south forks of Strawberry Creek. As time progresses and the environment changes it is important to keep track of how certain species are being impacted by these features, and how they cope with change. We hypothesized that due to the lack of pollution, the south fork will promote a greater diversity of macroinvertebrates. This was due to the fact that there was less runoff and trash that could be introduced to the water in the south fork, than there was in the north fork. We gathered data by analyzing the different organisms living in both forks. We collected a total of fifty vials composed of five organisms from each fork, and inspected them under microscopic view. After gathering data and identifying the different kinds of organisms living in the different forks we assessed whether the organisms from the samples could live in high or low resolution water. We also took a t-test to assess the probability of these differences being due to relevant factors or by chance. Our major findings suggest that organisms in the south fork showed a higher demand to living in cleaner water indicating that our hypothesis was correct.

The 7th graders took a nature hike and observed the nature around the Portage River. There, a nature expert talked about invasive species, seed distribution, and plants. When the water rises the seed pods come off of plants and float on the water, the seeds then are carried to new places. The 7th graders talked about how the monarchs are declining because of the lack of milkweed. They also talked about plants like goldenrod and poison ivy. Around the Portage River there are habitats like prairies, forests, and floodplains. Plants in the riparian zone help to filter the water before it goes into the river.

The arctic is estimated to be ice free by 2030 due to global warming and the melting of the ice caps.

Abstract: Microorganism need to live in ideal conditions so they can grow. This experiment was performed to determine if there was a greater number of microorganisms in Winthrop lake than Winthrop wetlands. We determined this hypothesis because the lake was bigger. We also made the hypothesis that the pH level of the lake was going to be higher than the wetlands. We tested out the hypothesis by going out to Winthrop lake and wetlands and collecting samples of water. Back in the lab, we examined the samples under a microscope and recorded all the organisms we could find on Excel. Also, we tested the pH levels of the

Brooker Creek is the largest natural area in Pinellas County. It is a preserved area where most of the organisms are protected by the state and cannot be touched or taken. This hike had a durability of one hour and it consisted on walking the entire trail and observing the different ecosystems found at the preserve. In order to see the different wild organisms that get to call the preserve home, we had to walk for around two hours. Some of the organisms mentioned by the guide of the hike and seeing at the preserve were: Golden orbs spiders, Coffee plants, lichens, mosses, sable palms, palmettos, blue gray knatt catchers, red maple trees, ferns, and tupelo trees. Although these organisms are very different from one another they are all able to live at Brooker Creek because of the different environments it has and offers its inhabitants.

Ecosystem Description: In this visit to Jonathan Dickinson State Park we had the opportunity to observe three ecosystems; Maritime Hammock, Dunes, and Mangroves swamp. The first ecosystem visited was Maritime Hammock This ecosystem occurs along the coast behind the dunes. It is similar as Hammocks’ forests that we saw in the Everglades but with a little bit less of vegetation. The temperature is nice and dry, not too much humidity. Maritime Hammocks are in general halophytic communities, this means that the vegetation here can tolerate the salty water bus doesn’t need it to survive. In this ecosystem we can found trees as oaks or grape fruits. The second ecosystem visited was Mangrove swamps. Mangroves lives in the estuarine zones. We appreciated

As important as it is, Arctic coastal sea ice plays a vital role in dynamics of the coastline, covers stretches of open water which serve as important biological habitats, and serves as a platform for a broad range of activities by residents and industries (Druckenmiller et al., 2009). Sea ice is also important because it is used as a platform for harvesting seals and whales in spring, transport of personnel and supplies to camps, and as a network of trails (Druckenmiller et al., 2009). Dangerous effects of climate change include “ice breakouts” which are when large chunks of ice that whalers are using as working areas break off of the main ice blocks and take whaling camps out to sea (Druckenmiller et al.,

The results of the observation of biodiversity on Mississippi State University campus was the wooded area contained eight different species, the water’s edge contained twelve different species, and the manicured lawn contained four different species. The eight different species in the wooded area are brown spider, black bird, pillbug, big red ant with black head, sparrow, earthworm, red-headed woodpecker, and bigger brown spider. The brown spider had a total of one species with a relative abundance of 0.0526. The black bird had a total of one species with a relative abundance of 0.0526. The pillbug had a total of three species with a relative abundance of 0.1579. The big red ant with black head had a total of five species with a relative

The diversity of plant and animal species in the Upper Lynn Canal remain among the highest in Alaska. Subarctic alpine, boreal forest, north coast forest, and marine systems converge at KLGO and the park hosts species assemblages found nowhere else in the world. Vegetation distribution is governed by a number of factors including soil type, depth, drainage, light availability, precipitation, temperature, disturbance patterns, and aspect and elevation. Specific vegetation communities in the park are not restricted to specific terrestrial ecological units and communities typically

The increasing global temperatures have caused many problems in Arctic ecosystems. The increasing warmth has caused ice caps to melt, and permafrost to thaw, causing shifts in the ecosystems around them. 1According to Harris (2005) “Permafrost is soil, rock or sediment that is frozen for more than two consecutive years. In areas not overlain by ice, it exists beneath a layer of soil, rock or sediment, which freezes and thaws annually and is called the "active layer".” (p. 17). While the melting of ice may not seem like a big issue at first glance, its effects are truly catastrophic. Many professionals in this field, such as Houghton (2009) have said 2“Warming is expected to be strongest in the Arctic, with the continuing retreat of

After conducted our research, this hypothesis proved to be incorrect. In the pre-settlement ecosystem, there were eight different species evaluated, however, in our research fifteen species could be accounted for. White Cedars were prominent in the pre-settlement ecosystem with a relative frequency of 35.8 while American Elms only had a relative frequency of 1.9. Although the frequencies of the species in the pre-settlement ecosystem appear to be higher, that doesn’t make the location more diverse. The area we evaluated was populated with numerous species, a characteristic crucial to forested areas. In addition, the total basal area for the pre-settlement system was 94.4 percent, a 5.57 percent difference from our 99.97 basal area

The Arctic is global warming’s canary in the coal mine. It is a highly sensitive area which is profoundly affected by the changing climate. The average temperature in the Arctic is rising twice as fast as elsewhere in the world (nrdc.org). Because of this, the ice cap is getting thinner, melting away, and rupturing. Here is an example of this; the largest ice block in the Arctic, the Ward Hunt Ice Shelf, had been around for 3000 years before it started cracking in 2000 (nrdc.org) By 2002, the Ward Hunt has cracked completely through and had started breaking into smaller pieces. The melting ice caps are affecting the earth and its inhabitants in many ways. In this paper, the following concepts and subjects will be

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.
