title: The Affects of Competition for Resources and Sunlight Exposure on Plantago major (Common Plantain) Leaf Size At York University's Danby Grassland

description: The dataset was collected on two separate days, it was collected on Monday October 19th, 2015. and Monday October 26th, 2015. The sampling took place at Danby grassland at York University in Toronto, Ontario between 3:00- 5:00pm. The weather conditions of the location on both days was windy and sunny and the temperature ranged from 10-14 . The experiment was done in groups of 4 which included Aziza, Sahar, Paula and Shahana. The purpose of this experiment was to observe if competition and distribution of resources, among plants affects plant size by using different sampling techniques. This experiment consisted of recording average leaf size, crowding, number of Common Plantain plants, total number of leaves, number of leaves in sunlight and sunlight percentage. The plant was identified by its oval leaves and a quadrat was used to sample the distribution of Common Plantain plants. The quadrat was placed randomly on the grassland 70 times on the first day and another 70 times on the second day. A total of 140 replicates was collected on both days. For each plant, the size of the leaves was determined by measuring from where the stem attaches to the leaf of the plant to the tip of the leaf. This was measured in inches using a measuring tape and the leaf sizes were averaged for each plant being observed. Crowdedness of the plant was determined by observing the amount of other plant species surrounding the Common Plantain. A scale was used which was 0=no other plant species, 1=very little plant species, 2= quite a lot of other plant species and 3= lots of other plant species. Sunlight exposure which was a percentage was determined for each individual plant, by dividing the number of leaves exposed to sunlight by the total number of leaves. This was then multiplied by 100 to get a percentage. There was not a large abundance of Common Plantain plants at the location which is why for some of the replicates there was no data. Low temperatures could have played a role which limited the abundance of Common Plantain in the grassland.

title: Sunlight and Vegetation Percentage in Danby Woodlot/Grassland

description: The purpose of the experiment was to determine whether a corellation existed between the amount of sunlight an environment recieves and the amount of vegetation it holds. The location of data collection occured on the Danby woodlot and grassland areas of York University, Toronto, Canada. Along with four other group members, data was collected between 3-5pm on two separate days: October 19th 2015 and October 26th 2015. The weather on October 19th was 14 degrees. partially cloudy and windy and on October 16th it was 10 degrees, mainly sunny and no significant wind existed. The amount of vegetation and sunlight in both environments (woodlot and grassland) was determined as a percentage. Sample locations were determined by a random number generator: beginning from the middle of each environment, two numbers were generated; the first (1-4) determined the direction (N, E, S, W) and the second (1-100) determined how many steps were to be taken in that location. Vegetation percentage was determined by using a 1 by 1 metre quadrat, only living vegetation that had it's roots in ground were counted. Sunlight percentage was also determined by using a 1 by 1 metre piece of blank cardboard which was laid just on top of the quadrat; the amount of sunlight that reflected off the cardboard was determined as a percentage. 50 samples were taken in each environment, each day: totalling to 100 samples for each environment.

title: Insect Abundance affected by Light and Habitat at Stong Pond

description: This experiment took place at York University, Stong Pond on October 19th, 2015 between 3:00-5:00pm (ET), with temperature at 12˚C, partly cloudy and windy (8mph). The same experiment was repeated on October 26th, 2015 between 3:00-4:30pm (ET), with temperature at 10˚C, mostly cloudy and windy (6mph). In the experiment, 20 pans were filled with soapy water, 10 were placed in the grassland and 10 were placed in the woodlot. Using the distance measuring tape, the pans were each 2m apart from the previous placed pan and they were left in each habitat for approximately 1 hour. The colours of the pans were light blue, red, yellow, white and dark blue which were used to attract different types of insects. The canopy coverage was measured by making a square with average human sized fingers to estimate the tree coverage (in percent, %) proportional to the sky coverage above each replicate. Sharon Dhami helped to set up the pan trap on the grassland while Syed Yusuf and Sarah Alsammarraie set up the pan traps on the woodlot. This procedure was followed for both Day 1 and Day 2 experiments for both habitats.

title: Effect of sunlight and crowding on common plantain leaf size at York University Danby Grassland using quadrats

description: On October 19 and October 26 from 3:00-4:45pm, at Danby grassland at the York University campus, a group of 4 observed common plantain species. On October 19, the weather was mostly cloudy with strong winds at a temperature of 16°C. The grassland was damp as it had rained the night before. On October 26, the weather was sunny with a slight wind gust at a temperature of 10°C. Sahar and Aziza worked as partners and so did Shahana and Paula, both pairs observing and recording data. The purpose of this study was to determine the effect of sunlight and crowding of plant species on Plantago major (common plantain) plant species leaf size in the Danby grasslands. Also, it was of interest to determine the influence of competition and distribution of resources for the common plantain. Quadrats of 1m by 1m were placed randomly in any direction of 3 steps from any previous quadrant in order to eliminate recounting of the same plant species already considered. The researchers were looking at numerous factors: number of species, average leaf size, crowding, number of total leaves in sun and sunlight exposure. Firstly, when each quadrat was placed down, the number of common plantains in each quadrat was observed for a period of 1 minute and recorded as number of species. Then each leaf size on each common plantain was measured and recorded, with the average later determined. Crowding was determined as a categorical approach: 0 for no plants around, 1 for little plants around, 2 for moderate plants and 3 for lots of plants around each common plantain. Sunlight exposure was estimated by counting the total number of leaves & number of leaves exposed to sunlight, which was ultimately converted to a percentage by dividing the two variables and multiplying by 100. This process was repeated 70 times each day, totalling a sample size of 140 quadrats.

title: Determining the Effect of Leaf Litter Coverage and Life Stage of Neighbouring Tree on Woodlot Insect Abundance

description: The purpose of the dataset is to determine how the amount of leaf litter on the ground and the life stage of neighbouring tree affects insect abundance in the Danby Woodlot at York University near Keele Street. A 1 m by 1 m quadrat was randomly placed beside the north side of an adult or sapling tree in the woodlot. An orange flagging tape was then wrapped around the neighbouring tree of the sample to prevent sampling in the same place. The percentage of the leaf litter coverage within the quadrat and the life stage of the neighbouring tree was visually determined and then recorded. All ages of leaf litter were included in the sample. Trees that are 2 m or taller are recorded as adult, otherwise recorded as sapling. The insect abundance in the quadrat was determined visually, physically counted for a duration of 3 minutes, and then recorded. The sampling procedure is performed for a total of 100 times in different areas of the woodlot. 50 of them were beside an adult tree, and the other 50 were beside a sapling tree. Data was collected on two different day. The first 50 data were collected during a partly cloudy day on October 14, 2015 from 2:55 pm to 4:45 pm. The temperature was about 12 degree Celsius and there was a slight breeze. The ground was mainly dry. The rest of the data were collected during an overcast day on October 21, 2015 from 3:05 pm to 4:45 pm. The temperature was about 9 degree Celsius and it was windy enough for small branches to sway. The ground was quite moist. More leaves have appeared on the woodlot's ground on the second day. Data was collected by Mandy Huynh, Dylan Stoll, Mariam Nnanna, and Jordan Deosamy. We splitted into group of twos to collect the data faster. Mariam and I worked together, while Dylan and Jordan worked together. Each group had a 1 m by 1 m quadrat and a roll of flagging tape. Each group sampled a total of 50 different area in the woodlot. Everyone had a chance to place the flagging tape on trees, use the timer, determine amount of leaf litter coverage, determine life stage of neighbouring tree, count insects, and record the data.

title: Wk6 & 7: Designing own experiment

description: We hypothesized that the abundance of insects varies related on the height of the plants. The taller the plants, the more insects will be present. The reason for this was because the plant height is related to the amount of rescoures it can provide to the insects (food, water, shelter). On two cloudy Tuesday afternoon, with temperature around 9 degrees celcius we were able to collect 40 sets of data from three different plant heights (unmowed, mowed and concrete) we saw that the results from our experiment confrimed with our hypothese. Unmowed grass clearly had more insects present, hiding under the leaves and the branches. While there were hardly any insects found on the concrete. Hence concludes that the height of the plants have a relationship with the abundance of insects present.

title: Crowdedness and Exposure to Sunlight Affecting the Size of Leaves of Plantago major Plants at York University

description: Data was collected on two seperate days, Monday October 19th, 2015 and Monday October 26th, 2015 between 3:00 pm - 5:00 pm at the Danby grasslands of York University, Keele campus. The site conditions were cool and windy on both collection days, ranging from 10 - 15 degrees celsius. The group collecting the data consisted of Aziza, Paula, Sahar and Shahana. The purpose of this experiment was to test the influence of competition and distribution of resources on plants in the grasslands by applying various sampling techniques. The experiment consisted of variables such as crowdedness, average leaf size, total number of leaves, the number of leaves exposed to sunlight and sunlight percentage. This tested whether the relationship between crowdedness and exposure to sunlight affected the size of leaves of the Plantago major plants, which were identified by their oval shaped leaves. Quadrats were utilized to sample the distribution of the plants for each replicate, which was randomly placed by a random number generator. A total of 70 replicates were used to sample the species of Plantago major plants each day, providing a total of 140 replicates for both collection days. For each individual plant being examined, crowdedness was assessed by observing the density of other plant species around the Plantago major plants. Sunlight exposure was measured by percentage, where for each individual plant, the number of leaves exposed to sunlight was divided by the number of total leaves that belonged to the plant. The size of the leaves were determined by measuring from the stem of the plant, to the tip of the leaf. The measurements of leaf sizes were averaged for each individual plant. The length of the leaves were measured by using a measuring tape. Low temperatures could have been a factor in the limited abundance of Plantago major plants in the grasslands.

title: Abundance of Dandelions Under Selected Ranges From a Major Road & Under Multiple Amounts of Litter

description: The abundance of dandelions was measured at three distances away from a major road (Keele Street), on October 19 and October 26, 2015, at York University, from 2:30 to 5:30 P.M. Weather conditions were partly cloudy, with a temperature of approximately 13 degrees Celsius. Quadrats were placed randomly at three distances: 3 - 15, 60 - 110, and 110 - 200 feet away from the main road. The dandelions (see metadata for species) found in each placed quadrat were counted, and results were tabulated and separated by their distance from the major road. The amount of litter and unintentional synthetic matter found in each quadrat was counted and recorded as well. woth each distinguiseable piece of litter counted as one (1) piece.
