title: Field Sample Training with Plants - Sampling tree populations & communities with transects and trait sampling techniques

description: Methods: In order to sample the woodlot, a transect measuring tape was used to measure a straight line from the edge of the woodlot to the center. Every instance we encountered an adult tree that was twice our height, we recorded the distance from one tree to the next, the diameter at breast height (dbh) of each tree, and its condition (0=dead, 1=living, 2=huge green canopy). This data was recorded for 10 pairs of trees, which is 20 trees in total. Study Site:This study took place on September 22, 2016 in Danby Woods at York University Keele Campus, Ontario, Canada. The weather was very hot and sunny with a little bit of rain and approximately 25 °C. Transect measuring tapes were used as equipment and to make measurements with. Hypothesis: There is a correlation between the distance as you go into the center of the woodlot and the living condition of trees because in the center of the woodlot, there are less environmental disturbances such as wind, allowing those trees to live longer. Also, since there is less sunlight in the center, as other tree canopies act as shade, trees that already have grown prevent new trees from growing, so trees near the center of the woodlot are bigger and older and trees near the edge are smaller and younger. Predictions: 1) As you go deeper into the woodlot, there will be more trees that are huge green canopies because those trees are older and have been able to live long because of less disturbances compared to trees at the edge of the woodlot. 2) As you go deeper into the woodlot, trees will grow closer together and the distance between 2 trees will decrease because sunshine is limited and trees want to cluster to share the nutrients and sunlight. 3) As you go deeper into the woodlot, the diameter of tree at breast height will increase because the trees in the center are bigger and older. Metadata: Pair - Categorical - A pair of two trees were sampled and used to gather data. Distance apart (m) - Continuous - A transect measuring tape was used to measure the distance from one tree to the next tree encountered on the transect tape. Measurements were in meters. Dbh (cm) - Continuous - A measuring tape was used to measure the diameter at breast height of each tree encountered. Measurements were in centimeters. Condition - Categorical - The following scale was used to categorize the living condition of each tree encountered: 0=dead, 1=living, 2=huge green canopy. Condition was determined by visual observation. Group members: Krysten Zarivnij, Avani Abraham, Monica Matta

title: Field Training with plants at York University; European Buckthorn (RhaImnus cathartica) DBH and canopy coverage in Danby Woods

description: <b>Methods & Materials:</b> In order to assess the relationship between European Buckthorn DBH and distance to other same species, 10 tree samples were studied. The survey was situated within the Danby Woodlot at York University (≈ 43.7735⁰N, 79.5019⁰W) The weather on Thursday September 22, 2016 was very warm with periods of sun and cloud. A very small amount of precipitation occurred that was insignificant. Students sampled 10 European Buckthorn trees within the Danby Woodlot and recorded DBH and distance from one sample to the next. Students used a tape measure to measure the distance and DBH and recorded results in a notebook.<br><b>Hypothesis:</b>The diameter of Buckthorn tree samples in the study would be dependent on the distance from other Buckthorn tree samples. Buckthorn tree samples with large DBH measurements would also have a high percentage of canopy cover. Large trees are likely to have more canopy coverage since they have more leaves. Trees close to trees with large DBH will consequently have smaller DBH measurements and a smaller percentage of canopy coverage since the larger canopies restrict sunlight to the small tree specimens.<b>Predictions:</b>1. Buckthorn tree samples near a Buckthorn tree with a large DBH will have smaller DBH measurements 2. Large Buckthorn tree samples with large DBH will have more canopy coverage 3. Samples with high percentage of canopy coverage will be the larger of trees sampled in this study<b><br></b><b>Group Members:</b> Krysten Zarivnij, Monica Matta, Vanessa Guo and Avani Abraham<br><b>Metadata:</b><b>Attribute</b>: Description <b>Buckthorn Sample:</b> Data was collected by sampling 10 adult European Buckthorn trees.

title: Techniques& Data: Field training in York University's Woodlot

description: Methods: On Thursday September 22, 2016 students sampled plant populations and communities by using transect measuring tapes to record the measurements from the edge of the woodlot to the centre. Lab mates measured the distance between trees, diameter at breast height, and its condition, for a total of ten adult trees. Each lab mate was tasked to consistently measure one attribute each to reduce error and inconsistencies. Study site: This study took place at York University’s Woodlot. This lab was conducted outdoors, the weather was mainly cloudy, humid, and a very light rain shower. Hypothesis: Tress at the edge of the woodlot would be smaller than trees closer to the centre of the woodlot, because humans are the biggest driver on the global planet and would cause less disturbance amongst tress further into the woodlot and its ecological system. Predictions: 1) The adult trees closer to the centre of the woodlot would have a greater diameter than the adult trees at the edge of the woodlot. 2) The adult trees at the centre of the woodlot would be taller(more than 3 times the height of one lab mate who’s height is 167cm) compared to the adult trees at the edge of the woodlot. 3) The adult trees in the centre of the woodlot would have green and fuller leaves compared to adult trees at the edge. Photosynthesis would enable the trees at the centre of the woodlot to absorb more nutrients and project a greener colour. Meta-Data:Attribues- Any tree that is three times the height of one lab mate who's height is 167cm. Distance between trees (Meter)- The starting point is 0 and tress were measured in meters, from one tree to the next. dbh- distance breast height, the same lab ,ever measured the dbh from their height consistently.

title: Field Training with Plants: A Study on Sampling Populations and Communities of a Plant Species in Grasslands

description: <b>Methods:</b> By randomly placing transect tape within the grasslands of Danby Woods, 50 individuals of a targeted plant species were sampled at specific distances on the transect for number of flowers, number of leaves, height, and whether it was located in a crowded patch of other plant species. <b>Study Site: </b>Danby Woods, York University, Toronto, ON, Canada. 43.7735° N, 79.5019° W. Study taken outdoors with a bit of rainfall and complete cloud cover. <b>Hypothesis: </b>There will be a correlation between plant height and surrounding density of other plant species because competition of nutrients between multiple plant species affects the ability of a single plant to grow and flourish. <b>Predictions:</b>1. The more crowded the target plant is by other plant species, the shorter it will be because as the nutrients are shared among many plants, the targeted plant species can only uptake a certain amount to sustain the plants life.2. The more crowded the target plant, the less number of leaves and flowers because it will be competing with other plants for nutrients which help produce more flowers and leaves.3. The targeted plant species will be taller, and produce more leaves and flowers in a less crowded area because they will not be competing for nutrients with many other plant species. <b>Meta-data:</b>1. distance (transect): Numerical and Discrete – Recorded distance traveled on a transect in meters to 50 targeted plant species which were sampled within a radius of 50 centimeters on each side of the transect to a maximum distance of 30 meters on the transect.2. height.of.plant.of.interest: Numerical and Continuous – Recorded plant height from ground level to tip of the tallest flower in centimeters using a measuring tape.3. total.number.of.leaves: Numerical and Continuous – On each plant, an average length stem was counted for number of leaves, and then that number was multiplied by the total number of stems on the whole plant itself to get the total number of leaves for each plant.4. total.number.of.flowers: Numerical and Continuous – Only counted purple flowers which were already bloomed and disregarded flower buds on targeted plant. 5. crowdness.around.plant.of.interest: Categorical and Ordinal – Assigned a ranking system of 0 (open), 1 (some plants nearby), 2 (quite a few plants), and 3 (very crowded bunch of plants) to signify the estimated density of the targeted plant’s environment within a 50 centimeter radius. <b>Group Members:</b> Matthew Fernandez, Rija Ghani, Niyousha Taati, Sarah Pecile
