title: WK3 LAB 2 BIO 2050

description: The dataset 3 was collected on September 22, 2015 at 3:56 pm by a group of 5 Ecology (Bio 2050) students. Data was collected near the Osgoode Library woodlot via transect measuring tapes. The group of students searched for any adult tree at the woodlot or in other words, any tree whose diameter was wider than the diameter of an average adult fist. Once the tree #1 was selected, the group proceeded to measure the tree's diameter. The measuring tape was held at chest height and horizontally extended to measure the diameter of the tree in meters. Afterward, the students assessed the living condition of the tree on a scale from 0 to 2 by observing the general appearance, number, pattern and coloration of leaves along the trunk and canopy as well as any presence of single or multiple dead branches. 0 on the given scale meant that a tree was dead; 1 meant that a tree was living or in acceptable living condition, while 2 indicated a huge green canopy. Then, students proceeded to measure the distance in meters from the tree of interest to the next adult tree by extending the measuring tape from the mid point of tree's trunk to the trunk's mid point of the next closest adult tree. It is important to note that all trees involved in the following collection of data were selected from the edge of woodlot to the center of woodlot moving in a North-South direction. After the first set of measurements, the group proceeded to collect the same type of data from 10 pairs of adult trees in total. The data was recorded, evenly shared amongst the group members and submitted to Figshare.com for assessment.

title: Sampling Milkweed population with transect, Dataset 2

description: This data was collected at York University grassland on September 22, 2015 at 3:00-5:00pm. My group members Amanda, Tonia, Michael and I conducted this experiment on a sunny day with temperature 21-22 °C. The plant species that this data was collected on is Common Milkweed (Asclepias syriaca). A transect tape was randomly placed in a grass field with many plant species in a straight line. Starting from the transect origin, and walking along it, on every milkweed individual encounter, it’s distance was measured from the starting point. Additional to its distance, every individual milkweed plant’s height, number of leaves (alive), and number of flowers were recorded. Whether the plants were in crowd of other species or not was also recorded (0 = Open area, 1 = few plants nearby, 2 = more than few plants nearby, 3 = very crowded area within 50cm). This study will give insight on how other species effect growth of Milkweed. This study will give insights on how other species effect the growth of Milkweeds.

title: Danby grasslands dataset of milkweeds using transects

description: The dataset was conducted at the Danby grassland at York University Keele Campus on Tuesday September 22 2015. The study took place during the approximate time of 2:30pm to 3:30pm. At the time of collection the temperature was 21 °C, with no clouds in the sky and some moisture in the soil. This study was conducted by Ecology students, which included myself, Katie, Katherine, Ava and Ashley. A transect tape was randomly placed on the grassland where Asclepias syriaca (milkweeds) were observed. The transect was 668 inches long and had a radius of approximately 39 inches (1m) on either side of the transect tape. Once a milkweed was spotted within the designated area a member of the team would count the leaves on the plant while height and distanced between the closest milkweed was measured. Once this data was collected we gave the crowdedness a number within the scale of 0-3 within a 50cm parameter (0 being next to no crowding, to 3 being crowded, see metadata for greater detail on scale). This process was repeated until 50 milkweeds along the transect line where documented.

title: Sampling Grassland Plant Populations Using Quadrats

description: This data was collected to sample grassland plant populations found in the Danby Woodlot at York University. It was collected on Tuesday, September 22 around 3:30 pm. Working with my partner Michael Sirianni, we used a 1 meter by 1 meter quadrat to sample the grassland 25 times. In order to ensure our sample was random, we began at the edge of the grassland and worked our way inwards, using a random number generator to determine how many steps to take each time the quadrat was placed down. After the quadrat was put down, we did a brief count of the total number of plants found in the quadrat. Then, we counted the number of individual species found. These include: Common Milkweed, Sugar Maple, Common Plantain, Common Thistle, Late Purple Aster, and Common Mallow. Next, we estimated a percentage of the total vegetation coverage in the quadrat. We also estimated the percent coverage of grass in the quadrat. These were estimations done considering the area of the quadrat as 100% and working backwards from that. It took approximately 40 minutes to replicate this process 25 times. Group members include Michael, Amanda, Phenil and I.

title: Lab2- Grassland dataset 2

description: This lab took place in the grassland at York University near the Aviva Centre to collect data on a target plant. In groups of two, one transect tape was placed along a path of goldenrod near the pond in the grassland from 0-300 inches. Once the first transect was placed the first partner walked along the transect tape and reported the distance of the first 50 goldenrods that were spotted and the second partner recorded all the findings. The distance was measured from the stem of the goldenrod to where it was spotted on the transect tape in inches. Then the height of the planst were recorded with a second transect, by measuring the goldenrod from the stem to the highest point of the plant. Next the number of leaves were recorded by only counting the leaves that were green and longer then 3 inches. Then the number of flowers were recorded by counting the bunching’s on the goldenrod as one flower. Lastly, the crowdedness was recorded by observing how many other goldenrods and other plants were surrounding the target plant. The crowdedness was measured by giving a number from 0-3, 0 being no plants and 3 being many.

title: Exploring Species Abundance in Danby Grassland at York University- Dataset 1 Lab02

description: Group Members: Mary, Shaneil, Prachi, Anthony, Gamsajny Data was collected at York University Keele Campus Danby grassland on Wednesday September 23rd at approximately 3:00 pm. It was about 22-23 degrees and very hot. The area was also dry. Upon reaching the grassland, our group split into two groups to cover a larger range. We picked a spot and positioned our quadrat and observed the quadrated area for the total abundance of plants, species richness, total percentage cover, and the percent cover of grass. The quadrat was 1m x 1m so the observed area had a surface area of 1m^2. The total abundance was calcluated by looking at the area in the quadrat and conducting a quick count of the number of plants observed in that area. Species richness was obtained by identifying different species and counting how many species there were in total. Total percent cover was obtained by observing how much of the quadrated area was actually covered by vegetation if all the plants were tightly packed. Grass cover was a percentage of how much of the total vegetation was occupied by grass. The quadrats were randomly placed and we repeated this process 10 times and our other group members also repeated this process 10 times to get a total of 20 data sets.All of the data obtained were mere estimates based on keen observation, although they may be very close to accurate, it cannot be certain that the numbers are highly correct as it was very difficult to accurately count each plant. This process familiarized us with the use of quadrats and exposed us to a large range of vegetation and to be able to identify many different plant species.

title: Data collection of black cherry plant in grassland using line transect method

description: The experiemnt was on data collection of black cherry plant in the grassland using Line transect method.It was conductedt at the York university grassland and woodlot and stated at about 3pm on the 22nd of September ,2015. The location of the research site is close to some residential houses . A group of four students, Stanley, sheran , Bryson and Nadura were divided into 2 groups,Stanley and Sheran did experiemnt 2 and 3 using transect measuring tapes while Nadura and Bryson did experiment 1 and 4 using quadrat and transect. the experiment. Experiment 2 was conducted by stanley withe the help of Sheran while experiement 3 was done in the woodlot and was conducted by Sheran assisted by Stanley. Experiment 2 was carried out on the garssland at a temperature of about 22 degree celsius and a particular plant black cherry was the sample . A tansect was placed randomly in one spot in the grassland and a transect measuring tape was place on the a stragit line and the distance between the initail spot and the first visible Black cherry plant in that line was recorded. Theheight, number of leaves ,number of flowers and the crowdedness were recorded. Then the data of the next plant in the line was also recorded. it continued untill the tape got finished at the 33rd sample.A random smaple generator was use to determine where to continue from by taking a random number from one to twenty . It happened that 8 was the number and so eight steps were counted to the left and the the experiment was started over from there. the transect measuring tape was again placed in a a straight line from that spot and the whole process of measuring the distance from the spot, height, crowdedness continued. The entire process was done for 50 samples and the data recorded.

title: Study of Insect Abundance and Diversity in a Grassland and Woodlot Habitat

description: On September 28 2015, the research group performed an experiment that focused upon the insect abundance, and diversity, in the grassland surrounding Stong Pond, as well as the Saywell Woodlot, on the York University campus. The study was performed between 3:00pm and 4:30pm when temperatures were 20 degrees Celcius and conditions were cloudy and very humid. It had also been raining prior to when the study was performed. A quadrat was used to analyze 10 locations in the grassland and 10 locations in the woodlot. Although locations were randomly selected, they were well spread out and covered the varying conditions throughout both environments. The only tool used in the field experiment was the quadrat as all the counts and categorization of insects into specific taxa were done with a visual examination of the site. Michael Chu, Diana Pik and Aisha Choudhry helped with obtaining the field data.

title: Woodlot Dataset 3: Sampling Adult Trees

description: This experiment was conducted on September 22, 2015 in the Danby Woodlots on the York University Keele campus between 4:40pm-5:10pm in collaboration with Naduni, Bryson and Stanley. The experiment was conducted on a bright, sunny day with clear skies with an external temperature of 22°C, however due to the canopy size of the trees in the Danby Woodlot, very little light got through and the actual site of the experiment was dimly lit. The purpose of this study is to get field training with plants and to familiarize myself with using sampling tools, such as transects, to collect data. This study was conducted by starting on the edge of the Danby Woodlot and using transect tape, we walked in a straight line towards the center of the Danby Woodlot. Every time we encountered an adult tree along our path (an adult tree is defined as a tree 2 times the observers height; at least 355.6 cm) we measured the diameter of the tree trunk at the observers breast height (137 cm) using transect tape. We also gave the observed adult trees a classification between 0-2 to represent the current state of condition of the tree (0 means the tree is dead, 1 means the tree is alive and 2 means the tree has a huge green canopy). Lastly, we also measured the distance between the current observed adult tree and the previously observed adult tree using the transect tape. After the 10th adult tree we observed, we ran out of transect tape so we used a random number generator and set the parameters to between 1 and 20 and got the random number 11. We decided to walk 11 steps North of where the 10th adult tree was and then set out the transect tape and walked in a straight line until we observed a total of 20 adult trees. The specimen of trees that were observed are Sugar Maples, or also known as Acer saccharum. This specimen was identified by observing the leaves of the studied trees and comparing then to the pictures provided in the Leaf Guide within our BIOL 2050 lab manual. The variables observed in this study were continuous and ordinal.
