description: The objective of this experiment was to observe the white aster species to determine if there is a correlation between phenotypic plasticity (number of leaves, height) and stress of the environment (abundance). The dataset for this experiment was collected over the course of two weeks in the grasslands of York University's Keele Campus. This region is an open area, with minimal shading and low human activity. The study had a total of 140 replicates (n=140). On the first day of collection (Thursday, Oct 15, 2015) the weather was moderately cold with a temperature of 18 degrees Celsius, slightly cloudy grey sky, with high winds and precipitation. On this day we recorded replicates 1-80 between 3 and 4:30 pm. All 80 replicates were observed in dim light, giving way to possible observation errors. A week later, on the second day of the collection (Thursday, Oct 22, 2015) the weather was 16 degrees Celsius with sunlight. On this day we recorded replicates 81-140 between 3 and 4:30 pm. All 60 replicates were observed in natural lighting provided by the sun. This allowed for clear visualization leaving little room for error and making data easy to collect. The materials included in this study were: pen and paper to record data, transect tape for height measurement and a quadrant (1 meter by 1 meter) to estimate the abundance. This study involved the active participation of all 4 group members, they include: Adilah Ismail, Amrutha Balamurugan, Harshvir Hehar and Olivia Kazmierczak. The methodology was meticulously planned prior to the execution of the experiment. All members of the group were assigned specific tasks to achieve the final dataset. This way all measurements and estimates were consistent over the two week data collection period. Amrutha was responsible for laying out the quadrant. All 140 placements were made very carefully to prevent observation of the same region. Adilah was responsible for measuring the height (in centimeters) of all replicates using transect tape. The plants were placed in an upright position prior to the measurement to ensure consistent recordings. Amrutha and Harshvir were responsible for counting the number of leaves. The number of leaves were counted by Amrutha and Harshvir using their fingers, given the criteria determined prior to data collection. This criteria allowed for the exclusion of all leaves below 3 cm as they were irrelevant to the experiment. The abundance was determined by all 4 group members. Olivia Kazmierczak recorded the data. Caution was taken to ensure that there was no recounting. All data was collected carefully to prevent disruption of the natural environment.

description: The experiment was conducted on October 15, 2015 and October 22, 2015 at Danby grassland, York university around 2:30-4:20pm. The temperature on October 15, 2015 was around 10° C with strong gusts of wind and was raining. The temperature on October 22, 2015 was around 15° C with clear sky and was slightly cold. The experiment was done along with Harshvir Hehar, Olivia Kazmierczak and Adilah Ismail. The purpose of the experiment was to study the role of density on adaptation of White Aster in terms of plant height and number of leaves on the plant. There was one quadrat and one transect used in the experiment. A metal quadrat (1 meter by 1 meter) was placed in random areas at Danby grassland where the White Aster species were found. Most of the data was collected at areas where the height of the grass was fairly low. The number of flowers which was present within the quadrat was counted simply with our eyes and was recorded. The number of leaves inside the quadrat was counted visually and only the leaves that were 3 cm in length or bigger was considered for the experiment while the small ones which were approximately 1 cm in length was excluded. The height of the plant was also measured using a belt transect measuring tape in centimeters from ground level to the tip of the plant. The abundance of the species was measured by visually looking at a small amount of species and multiplying that with the total area covered by the quadrat. The abundance of the species was low due to change in temperature on the second day of the experiment as it was slightly cold causing the species to die. The number of White Aster species observed on the first day of the experiment was 80 and the number of species observed on the second day was 58. Therefore the total sample size of the experiment was 138.

title: Ecology 2050- Insect Abundance VS. Pan Colours and Environment condition

description: Authors: Katrin Chapkis, Ava Kamali, Simranjit Kang, Jennifer Mariatha This experiment was conducted during two three hours sessions on Oct 15 and Oct 22, 2015 from 2:30PM to 5:30PM at grasslands, located adjacent to woodlots at Keele campus, York University. On Oct 15, the weather was cloudy and rainy with a temperature of 17 degrees Celsius. According to Beaufort Wind Force Scale, the wind speed was 4 which specifies a moderate breeze with a range wind speed of 13 to 18 mph. On the second day of experiment, Oct 22, the weather was partially sunny and cloudy with temperature of 14 degrees Celsius and Beaufort wind speed of 4. The temperatures for both sessions were interpreted as cold and the weather was not in its best condition, therefore there might have been a significant effect on the movement of insects. The purpose for this experiment was to observe whether three different pan colours and absence/presence of flowers attract insects differently. Also it was a good practice to develop teamwork and familiarize with designing and collecting our own experiment and data. For each session, soapy water, two transects and 12 plastic pans, which consist of three colours with ratio of 4 yellow: 4 white: 4 blue, were prepared and used. By observing the field, two distinct areas with certain characteristics were chosen as follow: one with flowers in great numbers and the other one mostly covered with grass. Distinction among the two areas was made based on our own assumptions. A transect line of 4 meters was laid across each selected area being studied. It was assumed if the number of flowers across that 4 meters were equal or less than five, the area will be recorded as ‘absence of flowers’; and if the flowers’ number were equal or greater than 20, the area will be recorded as ‘presence of flowers’. This step was repeated several times until the two distinct and preferred areas were found. Moreover, in each setting, 4 sets of white: blue: yellow plastic pans were lined perpendicular to the 4 meter transect line, each set 1 meter apart. The placement orders of pan colours were kept constant for each transects during two sessions. Furthermore, the soapy water was added to each plastic pan and group members left both areas to avoid any disturbance. After waiting for approximately two hours the numbers of insects (abundance) trapped in each pan for both areas was recorded.

title: Determining whether human and environmental interferences affect the height of plant species, Goldenrod, Purple Aster and White Aster.

description: The experiment was conducted at the Danby Grassland at York University for a span of two days, October 15, 2015 and October 22, 2015 between the times of 2:45-4:00 pm EST. The weather on October 15, 2015 consisted of cloudy skies with light periodic showers with an approximate temperature of 18 C. The weather on October 22, 2015 consisted of clear blue skies with an estimated temperature of 16 C. The Danby grassland was comprised of grass, scattered trees and variety of different plant species. It is to be noted, that due to significant weather changes during the period between the sampling days, resulted in reduction in the abundance of the plant species of interest, thus increasing difficulty in identifying them. The purpose of this experiment was to determine the height of specified plant species (Purple Aster, White Aster and Goldenrod) at each site within the grassland; the exterior and interior, in order to provide the required experimental evidence to reject or fail to reject the hypothesis formulated by the experimenters, whether reduced environmental and human interferences play a role in the height of the specified plant species. The exterior was identified by the experimenters as the 98.4 feet distance gap from the interior site. It is also to be noted that the exterior site was 84 feet away from the edge of road on Keele Street. The interior site consisted of dense, diverse and abundant vegetation as opposed to the exterior site that contained isolated vegetation, with boundaries that showed clear signs of mowing sometime during prior weeks. A total of 100 replicates were collected for each plant species, with 50 replicates from the exterior site and 50 replicates from the interior site. 40 replicates at each site was collected on October 15, 2015 and the remainder were collected on October 22, 2015. Each plant species was identified randomly at each site using the guidebook provided and later confirmed by all experimenters prior to measuring the height. The height was measured in inches using a transect tape with a total range of 100 feet, from the bottom of the plant to the highest flower. All measurements (based on the measurements on the transect tape) were recorded using the Imperial System to avoid accuracy and precision errors, had the experimenters converted to the Metric System. The sample size including all three plant species was 300. The experimenters were Bava, Saraswatie, Eman and Azeb.

title: The effects of interference and disturbances on plant height in a disturbed and undisturbed environment.

description: The data was collected by Bava, Eman, Azeb and Saraswatie (Davi) in the Danby Grassland at York University’s Keele campus on October 15th and 22nd, 2015 between 2:45 pm and 5:00pm. On October 15th, it was approximately 7 °C with regular intervals of light rain. On October 22nd, the temperature was approximately 13 °C with moderate winds and partially cloudy conditions. The grassland composed of mainly small plants, shrubs and grass with small trees located on the perimeter of the area. The grassland was visually divided into two areas based on the level of disturbances. The interior of the grassland was considered to be the undisturbed area while the exterior was the disturbed area. The exterior has an approximate width of 15 meters surrounding the undisturbed interior portion of the grassland. The disturbed area generally has smaller plants when compared to the undisturbed plants in the interior of the grassland due to human disturbances. Vegetation in the interior were taller but very crowded and as a result, was difficult to move around in. The purpose of this experiment was to determine if there is a variation in plant height in a disturbed and undisturbed environment and why. The question being asked was “Can environmental disturbances such as human interference alter the overall height of three different plant species?” We assumed that the plant height for plants in the disturbed environment (exterior portion of the grassland) would be much shorter when compared to the height of plants in the undisturbed area (interior portion of the grassland. The heights of three different plant species, namely, white aster, purple aster and goldenrod, were randomly sampled. These three species of plants were selected as they were the most common in the grassland and were located in both the disturbed an undisturbed areas of the grassland. The plants were identified using a plant guide book and differentiated by their leaves and flowers. Over the two day collection time span, there were 50 samples for each plant species in each sample area (disturbed and undisturbed) for a total of 100 samples for each plant resulting in a total of 300 plant samples. Using a measuring tape, the height was recorded from the base of the plant to its highest point at eye level. Only living plants were sampled.
