Weather: Partly cloudy, Temp: 24-29℃

Today marked our last day in the field, as tomorrow we are off to Ottawa to explore the nation’s capital. From the time we woke up in the morning, to the time we went to sleep we were working on our wetland assessment. Our group was assigned the Round Field Marsh wetland located on Opinicon Road, about 10 minutes from the Queen’s University Biological Station (QUBS). Today was a very productive day for our group, as we were able to do a great deal of species sampling within our wetland. Dr. Lougheed (Queen’s University) was also able to join us in the morning in order to conduct a bird count within the wetland, which was of great assistance to our group.

During the day, like other groups in our class, we had to divide our wetland into sample “quadrats” in order to make sampling of vegetation and other species in the wetland manageable. We had previously planned where our quadrats would be located using Google Earth, so all we had to do was use our GPS device to locate the UTM coordinates for our sampling sites. Our samples were evenly distributed throughout our wetland and were 1m by 1m in area. We found a lot of different species within our sampling sites, and we noticed differences in specie types depending how far we were from the location of the wetland that contained the most water. Some species found included: Goldenrod (Solidago), Queen Anne’s Lace (Daucus carota), Red Clover (Trifolium pratense) as well as Cattails (Typha Latifolia), which were more dominant in water saturated areas of the wetland.

Dr. Wang (Queen’s University) also joined our group today to give us a tutorial on water quality measuring devices. We used three different devices in order to measure the following parameters in the water in our wetland: dissolved oxygen, temperature, conductivity, turbidity, depth, total dissolved solids, the redox state, and pH. These parameters are very important in our understanding the water of our wetland. We also collected a sample of our water to bring back to the lab at QUBS.

During the evening we took all our data back to QUBS and inputted species found into a spreadsheet, as well as identified any species we were unsure of. We also looked at our water samples under a microscope to understand what microorganisms were in the water of our wetland. Overall, this was a very busy day!

[2015年8月6日]湿地评估

Scrambled-egg slime mold小队

今天标志着我们在野外工作的最后一天,因为明天我们将动身去渥太华开始我们的首都之旅。从我们早上起床开始,直到我们进入梦乡,这段时间我们几乎都在进行我们的湿地评估工作。我们的小组被分配到的湿地是Opinicon路一侧的Round Field Marsh,距离女王大学生物考察站(Queen’s University Biological Station,QUBS)大约10分钟的车程。对于我们而言,今天是效率很高的一天,因为我们有机会在湿地里对许多物种进行取样。洛希德博士(Dr. Lougheed, Queen’s University)也在上午的调查中加入了队伍,在我们进行湿地鸟类种类和数量调查中给予了极大地帮助。

在白天,就像班级里的其他小组一样,我们在湿地中选取了多个样方,由此对湿地的植被和其他物种进行取样调查。首先,我们使用Google Earth在UTM坐标上确定即将调查的样方位置,这些1m×1m样方贯穿整个湿地。我们在各取样点中找到了许多不同的物种,并注意到了群落物种构成随着距离湿地水域距离变化而变化。我们发现的物种包括he location of the wetland that contained the most water. Some species found included: Goldenrod (Solidago), Queen Anne’s Lace (Daucus carota), Red Clover (Trifolium pratense)以及Cattails (Typha Latifolia)——该物种在湿地水域中占据着显著优势,等等。

王博士(Dr. Wang, Queen’s University)则为我们讲解了今天水质测量工具的使用方法。我们总共使用了三种仪器,用于测定溶氧量、温度、导电率、浊度、深度、离子含量、氧化还原电位以及pH。这些参数均对于了解湿地水体特征具有重要意义。此外,我们还收集了一瓶水样带回QUBS以待分析。

夜幕降临后,我们将所有数据带回了QUBS,把所有物种信息输入表格中,并辨识了所有之前不能确认的物种。最后我们还在显微镜下检查了水样以确定其中的微生物群。总之,这是非常充实的一天!
