Abundance and variety of insects in the Grassland and Saywell Wooodlot situated in the York University community

The data was collected on September 28th, 2015 at approximately between 3-5 pm in the Grass land situated by Stong pond and the Saywell woodlot in the York University community. The temperature at the time of observation was 20 degree celsius, cloudy with winds. There had been rain slightly before arrival to the grassland and woodlot. The necessary and required equipments were one 1metre x 1metre quadrat. The data was collected to identify the abundance and types of bugs in both the mentioned habitats. Systematic sampling was in use, where every 10 steps the quadrat was placed. For each sample the quadrat was placed and observed for 2 minutes using a timer. In that time any bug that was within the quadrat as well as any directly flying above the quadrat was recorded. The area within the quadrat was slightly disturbed to make the bugs visible by manoeuvring the tall grass with a stick. This method was repeated 10 times in both the habitats for a total of 20 replicates. Descriptive notes of the insects were taken to later help identify the type of insect recorded for cases in which the insect could not be identified. Many bugs were found in both habitats which include: Garden spiders (order: Araneae) Ants (order: Hymenoptera) Flys (order: Diptera) Bees (order: Hymenoptera) Carolina grasshoppers (order: Orthoptera) Dragonflys (order: Odonata) Beetles (order: Coleoptera) Plant hoppers (order: Hemiptera) Meadow spittlebug (order: Homoptera) snails (order: Pulmonata)

本数据集采集于2015年9月28日下午3时至5时左右，采集地点位于约克大学校园内斯特朗池塘（Stong Pond）旁的草地与塞韦尔林地（Saywell Woodlot）。观测时气温为20摄氏度，天气多云且有风，抵达两处生境前曾有小幅降雨。所需采集设备为1米×1米的样方（quadrat）。本数据集的采集目的为明确两处生境中的昆虫类群与丰度。本次研究采用系统抽样法：每行进10步即放置一次样方。每个样方放置后，使用计时器计时2分钟开展观察，在此期间，样方内部以及正上方飞行的昆虫均需记录。为使昆虫显现，需用木棍拨动样方内的高草以轻微扰动样方区域。该采样方法在两处生境各重复10次，总计完成20次重复采样。研究人员同时对昆虫进行描述性记录，以便在无法直接识别昆虫种类时辅助后续分类鉴定。两处生境均发现多种昆虫，包括：园蛛（蜘蛛目，Araneae）、蚂蚁（膜翅目，Hymenoptera）、蝇类（双翅目，Diptera）、蜜蜂（膜翅目，Hymenoptera）、卡罗莱纳蝗（直翅目，Orthoptera）、蜻蜓（蜻蜓目，Odonata）、甲虫（鞘翅目，Coleoptera）、植食性飞虱（半翅目，Hemiptera）、草地沫蝉（同翅目，Homoptera）以及肺螺类蜗牛（肺螺亚纲，Pulmonata）
