In terms of percent coverage rank the colors on the Population Sheet from highest to lowest. Blue, Red, and Green would be the order of the hues. Red makes up 20% of the area (mine was 29-32%), Green makes up 15% of the area (close to my range of 15–16%), and Blue makes up 65% of the actual region. 2. How would the data change if 10 transects were run during this activity? This will differ; however, as more samples are taken and transects are added, there should be less variation within and between groups. 3. In addition to percent cover, what other information could be determined about each population using the transect data that was collected? The size and density of the populace (the number of people per unit of area or volume) can be calculated. 4. List three situations or types of organisms for which this type of population study is appropriate. This will differ. There are a variety of vegetation kinds in the wild, forest tree cover, and sessile (non-moving) aquatic creatures as potential candidates. For organisms that travel very little or not at all, transects are the best option. © 2016 Carolina Biological Supply Company
