Moisture vs Species Abundance

Data was collected twice over two weeks to determine if moisture levels in the woodlots and grassland effected species abundance. Group members included Taylor, Amena, Antoni and Keerthana. Data collection began on Monday October 19, 2015 between 2:50 pm - 5:00 pm the weather was 14 degrees Celsius, partly cloudy with winds of 26km/hour southeast and the humidity at 49%. Data collection continued on Monday October 26, 2015 between 2:50 pm - 5:00 pm the weather was 9 degrees Celsius, scattered clouds with winds of 14 km/hour southeast and humidity was 57%. Dambi Woods located on York Campus was the location of the data collection as there was both grassland (limited canopy) and woodlot (denser canopy). The grassland area had high grass with scattered tree cover and the woodlot area was a forest with more tree cover. Starting point was a specific tree located at the entrance of the grasslands and a tree located at the entrance of the woodlots. Using a random number generator, the number of steps between each quadrant was determined. 60 quadrants ( 1 m x 1 m) were laid out in the grassland area and 60 quadrants were laid out in the woodlot area. Each quadrant was observed for 5 minutes for insect (species) activity. Some insects that were spotted were red ants, flies, spiders, beetles, and grasshoppers. An overall species count was noted and then a breakdown of the species observed was noted.

为探究林地与草地的含水率是否会影响物种丰度，研究团队在两周内开展了两次数据采集工作。本次研究的参与人员包括Taylor、Amena、Antoni与Keerthana。首次数据采集于2015年10月19日（周一）14:50至17:00进行，当日气温14摄氏度，天气为多云间晴，东南风风速26千米/小时，相对湿度49%。第二次数据采集于2015年10月26日（周一）14:50至17:00进行，当日气温9摄氏度，天气为分散云量，东南风风速14千米/小时，相对湿度57%。本次数据采集的场地为约克校区（York Campus）的丹比林地（Dambi Woods），该区域同时包含草地（冠层覆盖有限）与林地（冠层更为致密）两种生境。其中草地生境以高草为主，伴生零星树木覆盖；林地生境则为树木覆盖度更高的森林群落。本次采样的起始点分别为草地入口处的指定树木与林地入口处的指定树木。研究人员通过随机数生成器确定相邻样方之间的步距，最终在草地生境布设60个1米×1米的样方，在林地生境同样布设60个1米×1米的样方。每个样方均开展5分钟的昆虫（物种）活动观测，本次观测记录到的昆虫类群包括红蚁、蝇类、蜘蛛、甲虫与蝗虫。研究人员首先记录了总物种数，随后对观测到的各物种的个体数量进行了详细统计。
