The Abundance of Living Species in Permeable and Impermeable Areas; YorkU.Pond-BaseballDiamond.18oct.2016.csv

Meta data The experiments were carried out on October 18th, 2016 starting at 2:50 PM to 4:30 PM. The weather was 24 degrees Celsius with fairly cloudy skies and winds of 33km/hr. The experiment was conducted at the Pond and Baseball diamond at York University near Stong pond. The coordinates that was recorded at the Pond area was; latitude of 43.771, longitude of -79.506627 and elevation of 151.32. The co-ordinates for the Baseball Diamond was: latitude of 43.768, longitude of -79.50731 and an elevation of 137.75. These coordinates were provided by the Lab Instructors. Data column headers: Census: Refers to sampling week Calendar date: continuous variable representing the date data was collected Campus: Categorical variable that relates to the cuniversity campus the data was recorded at. Group ID: Categorical variable refers to unique group in BIOL 2050 Labs Habitat: Refers to the two places where data was recorded, pond (permeable) or baseball diamond (impermeable). Rep: The number of times the experiment was repeated. Meters: The unit that was used to measure distance on the transect and to distinguish the woody plant as a tree. Experiment 1: Herbaceous Plants - Abi Rujbally Methods: A transect of 50m was used to measure several variable throught the experiment. For experiment 1, for every two metres along the transect, a 1m by 1m quadrat was randomly placed alternating from left to right. The abundance of native, exotic plants and the total number of flower heads within the quadrat were recorded. Grass was categorized as an exotic species, and surveyed over the quadrat, which was then multiplied by four to get a total estimate of colonies in the entire quadrat. This variable is quantitative and discrete. Twenty-five trials were performed near pond and the impermeable area (baseball diamond) Variables: abundance.native.plants: The abundance of native plants refer to plants that have developed or naturally occurred in Canada for many years. They were recorded by placing a quadrat every 2m on a 50m tape. The variable is discrete and continuous. Abundance.exotic.plants: The abundance of exotic plants refer to plants that are introduced from another country. The variable is discrete and continuous. Grass was categorized as an exotic species, and surveyed over the quadrat Total.number.flowers: Refers to the total number of flower heads in the quadrate. Experiment 2: Woody Plants - Fatana Rahmani Methods: Data collected was continuous data. Meters were used to determine distance. Two 25 meter transects were used for this data set. The first transect was placed 25 meters from the edge of the pond where the dense area of vegetation started and the second transect was placed right behind it, joining the two to make it a continuous transect of 50 meters in total. Every 2 meters was walked along the transect and the total number of trees also known as abundance that was about 0.5 meters on either side of the transect was recorded. What was defined as a tree was any tree that had a height greater or equal to 1.5 meters. The canopy coverage of that tree was then estimated by both hands making a square using fingers and estimating the coverage of vegetation on that tree. The ground coverage was done the same way but instead of the vegetation on the actual tree, the vegetation of the ground around the tree was observed and recorded. Once that was done, the total number of flower heads within that 1m was observed and calculated using the naked eye. The transect was carried out and repeated (walked, did not move the transect) 25 times to make sure this data was accurate both in the Pond area as well as the Baseball Diamond (Impermeable) area. Variables: Abundance woody plants: Recorded by counting all the trees that was observed when the 50 metres transect data was walked once. The tree was identified if it was 1.5 metres or greater in height. Canopy cover: Was the amount of vegetation on each tree, averaged up and measured in percentage. This describes the amount of leaves and vegetation that was visible on the tree when a square was made using fingers. Ground cover: Was done the same way as the canopy coverage, but on the ground and the amount of vegetation (including grass) was observed and recorded as a percentage. This was then all totalled up for the total number of trees and the mean was recorded for abundance. Total flower numbers: The average of all the flower heads found around 1 meter of the transect, around the tree, and was averaged for all the trees and recorded. Experiment 3: Vertebrates & Invertebrates - Bushrat Tabassum Methods The purpose of this dataset was to measure the abundance of living species (vertebrae, invertebrate and humans) in two different locations, York University Pond and York University Baseball Diamond. This experiment was performed by using the point survey method. The data was collected over two 15-minute intervals. A transect was used to create a 50-meter radius from any location. One individual was then responsible to observe and record any vertebrae within the radius. The total number of individual vertebrae was calculated and labeled as the abundance of vertebrae. At the same time, the total number of humans (not a part of the lab group) was counted and recorded as the abundance of humans. On the second 15-minute interval, the total number of invertebrate was observed and labelled as the abundance of invertebrate observes. The same method was used in two 15-minute intervals at York University Baseball Diamond. Variables Data type: Categorical Data. Individual: a single body of each species. Vertebrates species: species that have a backbone Invertebrates: species that do not have a backbone Species: living organisms that live in the same area and are able to interact and interbreed with each other. Abundance of humans: total number of humans which are not a part of our lab group, in a given area. Experiment 4: Invertebrates - Saarah Popalzay Meta-Data: The two methods used to measure the abundance of the invertebrates observed, was the pan trap method and the sweeping method. In the pan trap method 6 pan traps (one for each trial) was laid out 3 meters apart in alternating colours of yellow, white and blue along a 50 meter transect. Roughly 20 ml of soap water was added to the pan traps. The traps were laid out for a period of roughly 45 minutes from 3:00 pm to 3:45 pm. The number of species collected in each pan trap was observed and recorded. In the sweeping method, a butterfly net was used in a sweeping motion to collect insects along the 50 meter transect. Upon reaching the end of the transect, the number of insects collected was observed and recorded. The sweeping method was repeated for a total of 10 times and at the end of each trial the number of insects observed was recorded. The two methods were repeated for both the study sites. The The data collected for both methods is continuous as they as numerical and measurable sets of data in which each outcome may change for each trial. Hypothesis: There is a correlation between the abundance of living species with the abundance of vegetation. Alternative Hypothesis There is no correlation between the abundance of living species with the abundance of vegetation. Prediction: The amount of vertebrates and invertebrates are higher in the pond (permeable) location because the vegetation in the area provides a suitable habitat for the species.The abundance of vegetation is positively affected by the abundance of species due to the interaction plants and animals in a niche. Equipment used: 2 Transects 6 plastic bowls; two blue, two white and two yellow 1 sweep net 1 quadrat (1m by 1m)
