On October 13th, 2015 and Octover 20th, 2015 Muhammad Akram, Daniel Germani, Bonnie Duong and Markian Patwiak visited the Danby woods at York University in order to see if they could find a relationship between the size and conditioning of trees and the number of insects that could be found within 1m of 100 maple trees. We hypothesized that the size and conditioning of tree will have a direct correlatoin with the abundance of insects in the area. The number of insects present within a 1m^2 transect placed to the left (West) side of the tree was counted over a 60 second interval by all 4 members. Trees were categorized as either being dead and small, dead and large, alive and small, or alive and large based on greenery and evidence of trunk decay . The study took place over 2 days and over approximately 4.5 hours. On Day 1, October 13th, 2015 the data was collected from approximately 2:57pm - 5:05pm. Day 1 was a , cloudy day with moderate cloud cover, approximately 10km/h wind speed and a temperature of 15 degrees celsius. Data was collected from a total of 40 trees on this day, 10 from each category. Trees were analyzed from approximately 2:47pm-4:58pm on Day 2. It was also a moderatley cloudy day with slight precipiation throughout the time spent in the field. The temperature was at approximately 17 degrees celsius and wind speed was approximately 11km/h.
2015年10月13日与2015年10月20日,Muhammad Akram、Daniel Germani、Bonnie Duong及Markian Patwiak前往约克大学(York University)丹比林地(Danby Woods)开展野外调研,旨在探究树木尺寸与健康状况与其周边1米范围内昆虫数量之间的关联,采样对象为100株枫树。研究团队提出假设:树木的尺寸与健康状况,与该区域内昆虫的丰度存在直接相关性。
由4名调研人员共同计数放置于树木左侧(西侧)的1平方米样带内的昆虫数量,单次计数时长为60秒。基于植被覆盖情况与树干腐朽迹象,将受试树木划分为四类:枯死后小型、枯死后大型、存活小型及存活大型。
本次研究为期2天,总耗时约4.5小时。首日(2015年10月13日)的数据采集时段为当日14:57至17:05,当日共完成40株树木的采样,每类树木各10株。树木分析工作则于次日(2015年10月20日)的14:47至16:58开展。首日天气为多云,云量中等,风速约10km/h,气温15摄氏度。次日天气同样为多云,野外调研期间伴有小幅降水,气温约17摄氏度,风速约11km/h。
