How the abundance of insects is affected by the size and condition of maple trees within close proximity, in the Danby Woods.

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四人前往约克大学（York University）丹比林地（Danby Woods），旨在探究树木尺寸与健康状况，与100株枫树周边1米范围内昆虫数量之间的关联。本研究提出假设：树木的尺寸与健康状况，与其所在区域的昆虫丰度存在直接相关性。四人以60秒为计数周期，统计放置于树木左侧（西侧）的1平方米样带（transect）内的昆虫数量。根据植被覆盖情况与树干腐朽迹象，将树木划分为枯亡小型、枯亡大型、存活小型、存活大型四类。本次研究为期2天，总耗时约4.5小时。首日为2015年10月13日，数据采集时段为当日14:57至17:05左右。当日天气多云，云量中等，风速约10km/h，气温15摄氏度。当日共采集40株树木的数据，每类别树木各10株。次日为2015年10月20日，野外作业与数据分析时段为当日14:47至16:58左右。当日同样为多云天气，作业期间伴有零星降水，气温约17摄氏度，风速约11km/h。
