Ecology BIOL 2050 Lab 3 - Insect Abundance and Diversity (Dataset 1)

Group members: Kamil Adamczewski, Joelle Brooker, Brittney Jorisch, Karin Yosefi. Data for this experiment was collected at Danby's grassland and woodlot near York University on October 1, 2015 between 3:15pm and 3:38pm. The weather was sunny, mostly clear skies, and breezy with a temperature of 15 degrees Celcius. For this experiment, a 1 metre by 1 metre quadrat was used to sample the abundance and diversity of insects at both sites. The quadrat was thrown 10 times at each site for a total of 20 times (n=20). It was randomly thrown, there was no specific preference in throwing the quadrat in certain places. After throwing the quadrat, group members waited 1 minute to let the site that is being studied become stabilized. Then, the abundance of insects inside were visually estimated. Also, recognizable taxonomic units of the insects were accounted for by visually noticing any differences in structural features such as wing type, body type and colour. Since it was a cold day (15 degrees Celcius), not much insects were observed, thus the data collected was quite low. The purpose for collecting this data was to determine a correlation between the abundance of organisms in a defined area with the amount of diversity present.

数据集团队成员：卡米尔·亚当切夫斯基（Kamil Adamczewski）、乔尔·布鲁克（Joelle Brooker）、布里特尼·约里施（Brittney Jorisch）、卡琳·约塞菲（Karin Yosefi）。本实验的数据采集于2015年10月1日，地点为约克大学附近丹比的草地与林地，采集时段为当日下午3时15分至3时38分。当日天气晴朗，天空整体澄澈，微风习习，气温为15摄氏度。本实验采用1米×1米的样方（quadrat）对两处样地的昆虫丰富度与多样性开展采样。每个样地抛掷样方10次，总计采样20次（n=20）。样方抛掷为随机操作，未对特定投放位置存在偏好。每次抛掷样方后，研究团队需等待1分钟以使采样区域恢复稳定，随后通过目视估算样方内的昆虫个体丰富度；同时，通过观察昆虫的翅型、体型、体色等结构特征差异，记录可识别的昆虫分类单元。由于当日气温偏低（15摄氏度），观测到的昆虫个体数量较少，因此本次采集到的数据量相对有限。本数据集的采集目标为探究划定区域内生物个体丰富度与物种多样性之间的相关性。
