title: BIOL 2050 LAB 2 Abudance of white flowerig plant species within a 25 meter distance at York University Grassland.csv

description: <b>Description:</b><br>The following dataset illustrates the abundance of white flowering plant species in a 25m range, located at York University Grasslands.<br><b>Methods:</b><br>A transect was used to collect the data within the grassland. The 25m transect was placed in a straight line along a random patch of land in the area. One person was responsible for walking along the transect and identify the target plant species. Every time the target plant species would fall along the transect line, the distance from the transect to that plant was measured (in memters) and recorded. <br><b>Metadata:</b><br>The data was collected on York University Grasslands on September 20th, 2016. The weather appeared to be sunny with light clouds and no wind disturbance.<br><b>Target plant: </b>The type of plants that were observed were small, white flowering plants. <b>Distance of transect:</b> A 25m transect was set in a line along a random patch of land on the grassland. Once a target species fell on the transect line, it's distance from the base of the line (0 m) to the target species are measured. <b>Distance off transect line:</b> Although most plant species appeared to fall on the 25m transect line, some plants were seen to be a few centimeters away (maximum 5cm) from the original tansect line.

description: This study was conducted to measure the diameter at breast height (dbh) of adult trees in pairs and the distance between them in woodlots, at York University around 3:30pm- 5:00pm.<br><br>Location: Data was collected at York University, at Keele St. and York Blvd, in the Woodlots.<br>Methods: In this field experiment, transects measuring tapes were used to determine the distance between 10 pairs of sugar maple trees. The diameters were measured from the middle of the tree trunks, using a tape measure. Canopy coverage was determined by making square with fingers and holding it up, in order to gain an estimate regarding how much of the sky was seen. <br>Key to variables: Diameter at breast height (dbh), distance to nearest species, and canopy coverage were continuous and quantitative variables. <br><br>Prediction: It was predicted that the distance between two trees with a low dbh would be less than those with a greater dbh, since the smaller the dbh, the smaller the tree and therefore, the less branches and canopy coverage it would have.

description: This experiment examines the relationship between adult trees and saplings – more specifically, tree diameter, distance, and canopy coverage. <b>Methods:</b> -The experiment took place on Tuesday, September 20, 2016 from approximately 3:00-5:00 pm in warm weather conditions. 10 adult trees were randomly sampled and measured in comparison to saplings on the York University Keele campus using measuring tape and transect measuring tape. -For each adult tree that was sampled, its DBH and extent of canopy coverage were determined, followed by its distance to the closest sapling and the sapling’s DBH. DBH was determined by wrapping measuring tape around the tree’s trunk while the distance between adult tree and sapling was determined using either the measuring tape or transect measuring tape, depending on the distance. -The data was recorded in a notebook and later copied onto an Excel sheet. The data on Excel would then be uploaded to Figshare. <b>Hypothesis: </b> -The length of an adult tree’s diameter will have a direct correlation on the sapling distribution and size around it. <b>Prediction: </b> -The DBH of sapling is always less than the DBH of adult trees around it. -The larger the DBH of adult trees, the higher the percentage of canopy coverage. -The larger the DBH of the adult tree, the greater the distance it is from its closest sapling. -The competition and scarcity of resources make the adult trees and saplings not be close to each other. <b>Meta-data:</b> -DBH (cm) = Diameter at Breast Height; the diameter of the truck at chest level for the adult tree. The data is quantitative and continuous. -Extent of canopy coverage = An estimated percentage of sunlight coverage by the leaves, looking straight up. The data is quantitative and continuous. -Distance to nearest sapling (cm) = The distance between the adult tree and the sapling, both of the same species. The data is quantitative and continuous. -DBH of sapling (cm) = Diameter at Breast Height; the diameter of the trunk at chest level for the sapling. The data is quantitative and continuous.

description: This study was conducted to measure different plant species in the grassland and compare the ratio of grass to the other kinds of vegetation at York university, around 3:30pm- 5:00pm.<br>Location: Data was collected at York University, at Keele St. and York Blvd, in the Grasslands. Weather condition near the field site was sunny.<br>Methods: Field experiment was conducted using quadrat sampling technique. This technique involved the use of quadrats that were in a square frame, made of pvc piping, which measured 1 m2 area. In the study, 25 trial were conducted within 1.5 hours. Half of the measurements were done by counting areas that were under the sun, where as the other half were under the shade. In each trial, the number of the plants, species, the total population of the grass, as well as vegetation were recorded. <br>Key to Variables: The variables in this field experiments were: number of plants, the number of species, the total population, percentage of vegetation and grass coverage . Number of plants and species and total population were quantitative and categorical type. They were all counted from top left to the bottom right of the quadrant. The percentage of vegetation and grass coverage are quantitative and categorical variables.<br>Prediction: It was predicted that the sites located under the sun would have a greater variation of species, since different types of vegetation require more sunlight energy in order to grow taller, as compared to grass. <br>Hypothesis: Grass is more abundant under shaded areas, than areas exposed to sunlight. The abundance of vegetation decreased in the shade.
