title: The effect of plant density and distance from the pond on insect abundance- Data

description: We were trying to see if the distance from the pond or/and the plant density will affect the insects abundance in grassland. We were doing that by counting the number of insects and calculating the plant density in a 1X1 (squared meter) quadrants in three different distances- 1, 10 and 20 meters away (vertically) from the pond in York University grassland area above the Pond street. We placed the quadrants so they will be a meter apart (to the side of the previous quadrant) in every distance. We have done it in two different dates, October 13 and October 20 in 2015. Here you can find the data we found and a decriptive explantion of how exactly we were doing so. Worth to mention that the tempature was simmilar in this two dates; however, the wind was much stronger on October 20.

title: Affect of Sunlight and Soil Moisture on Plant Abundance and Surrounding Ecosystems

description: This experiment was conducted over the span of two days: October 13th 2015 and October 20th 2015 in the Danby Woodlot and the Danby Grassland at York University Keele Campus from approximately: 2:50-5:00pm both days, with group members Houra, Alexandera and Kathy. The weather was approximately 18°C on both days. On the first day the experiment was conducted it was severely overcast with a lot of cloud coverage while on the second day there was some cloud coverage and light showers towards the end. All the grassland replicates were collected by Houra and I, in order to keep data/measurements reliable and consistent. The overall purpose of this lab was to develop collaboration skills in field ecology & data collection, but specifically collect data to find a relationship between sunlight and soil moisture and how they affect plant abundance (and ecosystems) respectively. A total of 160 trials were to conducted over the span of two separate days, 80 in both the grassland and woodlot. A random number generator app was used to ensure random sampling. A random number of steps were taken in a a specific direction and the 1x1 meter quadrat was placed on the ground. The total number of plants were recorded, along with the moisture levels of the soil, and exposure of sunlight. The moisture of the soil was tested with a paper towel wrapped around a popsicle stick and being pushed into the ground, and was given a number from 0-2. The amount of sunlight the quadrat was being exposed to was given a number from 0-3. Both size classes are further explained in the meta data. This procedure was repeated 79 more times for both the grasslands and woodlot, 40 replicates for grassland and woodlot collected in each field day. It was concluded that due to the poor weather conditions cloudy and rainy) the exposure to sunlight may not have been accurately depicted.

title: Insect Density Versus Plant Density

description: The data presented is a dataset of insect density per meter squared versus the plant density of the area both were collected in. One meter squared quadrats were randomly placed 30 time each in both a grassland and in a mowed lot. Insect abundance was determined by thorough observation of the area in question, plant density was approximated using the quadrats as guide. Plant Density was determined by counting the individuals in one fourth of the quadrat, then extrapolating to the rest of the area in question.Data was collected in late October in temperatures ranging between 10-17 degrees celcius. A large portion of the data was collected during cooler than seasonal temperature, and following rainfall which may contribute to the results. Insect abundance was determined without substantial disruption of the areas being surveyed. The areas surveyed may have been subjected to human interference and presence.

title: Study of Human Disturbance and Canopy Coverage on Plant Abundance and Species Richness at York University

description: On October 19, 2015 and October 26, 2015, an experiment on the abundance and richness of species was conducted in the Saywell Woodlot and Stong Pond Grassland, located at York University. The experiment was conducted between 2:45pm and 4:30pm. The average temperature on both days was 16 degrees Celsius with cloudy skies and a low humidity. The objective of the study was to determine whether Human disturbance and Canopy coverage would affect species richness and plant abundance of the various organisms found in each habitat: Grassland and Woodlot. The experiment was conducted for each habitat; total of 30 replicates per habitat. A 10 m transect was laid out in both the Grassland and Woodlot. Experimenters walked along transect and counted the total abundance of species and the different types of species found within a 1 m reach of transect. The Canopy coverage along transect was recorded by creating a box with fingers and estimating the percentage of sky that can be seen. The amount of Human activity was also noted on a scale from 0-2: zero to be no disturbance, one being light human activity, and two being heavy human disturbance. Human trafficking was also taken into consideration. Experimenter’s recorded all observations found in both habitats. Ron Kleiman, Gurjot Muker, and Mohammad Imrit helped with obtaining this raw data. Once the experiment was complete, transect was collected and returned.

title: Measuring insect abundance depending on the effect of light and habitat at York University'

description: Purpose of this experiment was to determine if the amount of light in a particular habitat affected the insect abundance. This experiment was conducted on October 19th, 2015 and October 26th, 2015 at York University at approximately 15:00 (EST) for both days. On October 19th, 2015 the skies were partly cloudy, the temperature was 13 degrees Celsius, and the wind speed was 8 mph. On October 26th, 2015 the skies were fair (showed less than 40% cloud cover), the temperature was 10 degrees Celsius, and the wind speed was 6 mph. The experiment took place in two locations: Stong Grassland and Saywell Woodlot. Sharon Dhami and Anosha Rahmany gathered data in the Stong Grassland. Data was collected in Saywell Woodlot by Sarah Alsammarraie and Yusuf Syed. Data was collected by using ten pan traps in the grassland and ten pan traps in the woodlot. A line transect tape was used to measure two metres in between each positioned pan trap. Ten pan traps were placed in alternating colours (no two pan traps of the same colour were adjacent to one another). Soapy water was poured into each pan trap and then they were set out for one hour in their habitat. After an hour had passed, the abundance, RTUs, and canopy coverage was recorded at each positioned bowl. The canopy coverage was obtained by positioning fingers to form a square, placing up to chest height, and looking through the square in order to estimate the percentage of tree visible in proportion to the amount of sky in the square. This method was used for both Day 1 and Day 2.

title: Measuring insect abundance depending on the effect of light and habitat at York University

description: The purpose behind this experiment was to determine the effects of habitat and amount of light on insect abundance. This experiment was performed at York University, at two different locations: Stong pond grassland and Danby woodlots on October 19th, 2015 and October 26th, 2015. The experiment time was approximately constant for the two days, around 3:00 pm. For the first day of experiments on October 19th, 2015 temperature was around 13 degrees Celsius, with wind speed at 9 mph and clear skies. On October 26th, 2015 temperature was 10 degrees Celsius, with a wind speed of 6 mph, skies on that day were more cloudy compared to October 19th, 2015. Data were collected in Danby Woodlot by Sarah Alsammarraie and Syed Yosuf, while Stong pond collection was done by Anosha Rahmany and Sharon Dhami. Data were collected using ten pan traps in the grassland area and ten pan traps in the woodlot area. Transect tape was used to measure 27 meters distance in a straight line into the woodlot allowing 3 meters between each pan trap. Ten pan traps of different colors were placed in an alternating order were no two consecutive color were the same. Pan traps were filled with soap-water solution; about half of the pan was filled with the solution to trap the insects in and the pans were set for an hour in the two habitats. When an hour had been passed, the insect abundance, canopy coverage and RTUs were measured at each location where there was a pan trap positioned. Canopy coverage was estimated by creating a square in the air above the pan trap using two fingers from each hand and raising the square along head height and looking through it to estimate the percentage of sky visible through that square. The exact same procedure was followed in day 1 and day 2.

title: Lab 4 Data - Tree Growth

description: Authors: Kamil Adamczewski, Joelle Brooker, Brittney Jorisch, and Karin Yosefi On Thursday, October 15th, 2015, at 3:00 pm and on Thursday, October 22nd, 2015, at 3:10 pm, 50 different individuals of Maple trees in the Danby Woodlots at the north-east side of York University were randomly selected and observed for 3 different variables. The first was the diameter at breast height (dbh) of the Maple tree as an indication of tree growth. This was determined by using a transect and measuring the diameter of the trunk of the Maple tree starting at the zero mark and at a constant breast height of approximately 1.6 metres. This was recorded in centimeters. The second was the percentage of canopy coverage surrounding the randomly selected Maple tree being observed as an indication if the amount of light the Maple tree is receiving. This was approximated by creating a square with the thumb and forefinger of each hand and raising the square up towards the canopy directly surrounding the Maple tree. It was then determined how much of the total square was being covered by the canopy. It was measured as a percentage out of 100. 0 being no coverage at all and 100 being complete coverage of the square. Canopy of all tree species in the vicinity was included in this measurement. The third variable was abundance of other plant organisms surrounding the Maple tree found within a 3 by 3 metre quadrat as an indication of the density of life around the Maple tree. This was approximated by using 2 transects measured at 3 metres and placing them to create one corner of the quadrat, the other corner was estimated by using the end points of the laid out transects. The Maple tree being oberved was roughly in the centre of the quadrat. Observation was done by walking within the quadrat and noting the quantity of any other plant organisms within the quadrat. This quantity did not include any dead organisms, but did include grasses and small shoots found. The purpose of these observations was to determine if there is a relationship between tree growth, light and density. The data was collected in the Danby Woodlot, at the north-east side of York University, Keele campus. The Danby Woodlot is a fairly dense area of various species of trees including Maple and Oak trees. There is a slight amount of dead or broken trees and branches littering the ground. On the first date, October 15th 2015, the temperature was 11 degrees Celcius, and it was very windy and cloudy with mild percipitation. On the second date, October22nd 2015, the temperature was 13 degrees Celcius, and it was sunny with a few clouds and slightly windy. The sample size was 50 Maple trees.

title: Effects of Soil Temperature and Density on Goldenrod Growth in the Stong Pond Grasslands at York University

description: On Monday October 19th 2015, at approximately 3:30pm to 5:00 pm an experiment including 25 grassland plots around Stong Pond at York University were examined to collect data on soil temperature, density, goldenrod plant number and the number of branches. The weather that day was slightly windy, at a temperature of 16 degrees Celsius. The goal of the team was to assess the effects of the soil temperature and the density on goldenrods at York University. A one by one-meter quadrat was placed around various grassland plots to determine what characteristics would favour plant growth. The measurement started off at the edge of the pond, and moved up toward the road. Each quadrat was placed approximately three large steps upwards, from the last. Density was measured by eye, and estimated to a percentage. The number of individual plants and braches were counted individually by experimenters. The thermometer was placed in the middle of each quadrat and the reading was taken after all the results were noted, leaving it more time to adjust to the correct temperature. The only tools used during the experiment was the quadrat and the soil thermometer. No goldenrods that touched the outside of the quadrat was included in the experiment, only the plants within the quadrat was used in the experiment. This experiment was replicated once more the following week on Monday October 26th 2015, when the weather was cooler at 10 degrees Celsius. The second experiment was an exact copy of the first experiment, where the experimenters measured density, soil temperature, individual plant and branch number, starting from the edge of Stong Pond and finishing off at the opposite edge of the grasslands, near the roads. This experiment was done with the assistance of lab members Danika Gordon, Karen Lin, Israt Hossain and Raman Singh.

title: Correlation between Plant Abundance and Soil Moisture in the Saywell Woodlot and Grassland near Stong Pond

description: The data was collected on York University Campus Grounds at the Stong Pond Grassland and the Saywell Woodlot. The data was collected over a period of two days; October 19, 2015 and October 26, 2015 at approximately 3pm both days. October 19, 2015 the weather was windy with partial sun and cloud, the temperature was 15 degrees celsius. October 26, 2015 the weather was very windy and cloudy, temperature was 10 degrees celsius. The required materials for the experiment to be conducted were a 1m x 1m quadrat, a small shovel/spoon, ball. 70 replicates were done in the Grassland habitat and 70 in the Saywell Woodlot. Standing at the edge of both the habitats a ball was tossed while keeping eyes closed, ahead into the area for the placement of the quadrat. Where the ball fell was where the quadrat was centered around. The subsequent placement of quadrats followed this method. Once the quadrat was placed one person was assigned the role of estimating the percentage covered by grass and vegetation. If there was an area that was primarily soil and had no vegetation it was excluded in the calculations. For example if the quadrat had 40% grass and 20% vegetation then the remaining 40% was soil, and the total area that had any type of vegetation was 60%. Then the soil was sampled and analyzed using the United States Department of Agricultures guidelines “Estimating Soil Moisture by Feel and Appearance" [1]. Using the spoon or shovel, the soil was dug up from a depth of 3cm. The soil was taken into the palm of the hands and squeezed into a ball. Observations of the balls firmness, soil texture, soil colour, soil stains on fingers, loose particles from ball were made and used to categorize the moisture level of the soil. Soil moisture was placed into one of the four categories; 0-25%, 25-50%, 50-75% and 75-100% (least moisture to most moisture). [1] [USDA] United States Department of Agriculture. 1998.
