The 4th day at QUBS – geocaching extravaganza. August 18th
Post by Team Eel.
Today we started off the day with a GPS scavenger hunt, otherwise known as “geocaching”. We were given the UTM coordinates for 6 locations on Queen’s University Biological Station property that contained fluorescent pink flagging tape and biological questions that our groups had to answer. We were also given a GPS in order to help us find these locations – our group plugged in each location as a “waypoint” and traveled along the most efficient route in order to retrieve all 6 questions. Unfortunately there was a typo in one of the location’s coordinates, resulting in some interesting escapades in an attempt to find said location. Our group personally tried climbing over fences, hills and navigating through wetlands to try and find the location, all to no avail of course. Our GPS also died halfway through the hunt, so we partnered up with two other teams. It was really fun using the GPS and watching the arrow representing our current position slowly move towards each respective location. It was also rather amusing (though not at the time!) to see a trail of our attempts to locate the missing location with the typo in its coordinates.
After the geocaching exercise we retrieved a NAME net with two canoes that we had set up along
the shoreline the previous day. We caught a variety of small fish such as bluegill, pumpkinseed, rockbass and yellow perch. Unfortunately one of the captured fish jumped out of the bucket and landed underneath a section of the dock that we could also reach through a small crack. Several of the students tried in vain to rescue the small bluegill by flushing it with water and attempting to use newly-found chopstick skills to fish it out of the crack. After about 20 minutes they were successful in removing it, but even after some mouth-to-mouth the fish slowly passed away. However, the fish did not go to waste as it was tossed back in the water where some larger bluegills happily consumed it.
Following the retrieval of the NAME net, students were assigned to one of two wetlands in order to complete a wetland analysis for use in a future assignment. Students collected data on the dominant plant and animal species present, the percentage and fractional area of vegetative forms, the water quality and chemistry, soil types, water sources and much more information that will be compiled and compared at the end of the course. Our wetland, called Beaver Marsh, was covered in a variety of tall shrubs and emergents, with very little open water. It was interesting to perform the analysis ourselves as it gave us a better appreciation of the work that goes into the assessment of wetlands and other habitats.
After we compiled data from the two wetlands we had dinner and then attended a guest lecture by Dr. Emily Gonzales. She is working at St Lawrence Island National Park. She introduced about developing of National Park in Canada. Following the guest speaker, we had two students presentation. The ebullient Edwina Dai talked about Farm Fishing in Canada. The incomparable David Chang presented the relationship between agricultural and freshwater ecosystems.
有趣的寻宝活动之后，我们用两艘独木舟回收了设在船坞附近岸边的NAME鱼网。网中我们发现了一些bluegill，pumpkinseed，rock bass和yellow perch之类的小鱼。不幸的是，一条小bluegill跳出了水桶还陷在了船坞的木板里。几个学生试图用细树枝把它夹出来，同时不断给它浇湖水。经过了大约20分钟的努力，小鱼终于被救了出来。但就算给它做人工呼吸，小鱼还是渐渐死去了。我们没有办法，只能将其放回湖中，至少它还能被其他大太阳鱼吃了当午餐。
之后我们汇总了两个湿地的信息。晚饭后我们听了Emly Gonzaks关于圣罗伦斯岛国家公园的报告。她介绍了很多加拿大的国家公园。之后我们的两个学生分别作了报告。Edwina Dai介绍了加拿大的养鱼业，而David Chang则介绍了农业和淡水生态系统的关系。
