Giant Swallowtail monarch butterfly
Today was our first day in the field
We arrived at our Marsh following a ten minute drive through the rolling countryside that surrounds QUBS. Our particular wetland is a palustrine marsh which fills in during spring flooding and then dries up over the heat of the summer. The water covered areas of our wetland are thus quite minimal as it is late August.
Though we have all worked to develop the skills required, our team members each brought an individual strength to the wetlands survey exercise. Ding has become the master GPS operator, taking a complete survey along the circumference of the Marsh. Yueting is particularly adept at identification of plants, using her past experiences with plants surveying in China to create a list of the plants in our wetland. Qi, Leslie and Yueting are also all interested in photography, thus our group was lucky to end the day with a nice supply of great shots of Round Field Marsh.
To name a few species we saw during
the day, we saw a monarch butterfly (Danaus
plexippus) fluttering about the milkweed (Asclepias syriaca) off the edge of the marshland. We saw several leopard frogs (Lithobates pipiens) and a few others
that were too quick for us to see. We
also saw a few snakes, however we on
We came across a few challenges along the way. As our wetland has minimal water compared to the other marshes, an accurate measurement of the shoreline proved challenging. We came across another challenge in measuring invertebrates within the waters of the marsh- the grasses growing in the area covered too much of the soil to enable a dip net to capture a large amount of life within the water. We were able to work together and collaborate on ideas to overcome these challenges. We found this was both a useful and interesting enhancement to our wetland study; although coming across challenges can seem surprising and intimidating, it’s very normal (and almost inevitable) in the field of science to come across obstacles. These challenges must be tackled using creativity, insight, and in our team environment using a collaboration of team members ideas resulting in an optimal method.
Overall, we thoroughly enjoyed our day in the field. We loved the challenge and excitement that is taking knowledge and theory learned in class into the field.
今天是湿地考察的第一天，每个小组各自分配到了一片湿地进行研究。我们小组的湿地是Round Field March，研究内容包括湿地内的动植物和重要特征如水质等的调查。这是一片由春季雨水形成的湿地，由于现在是夏季，只剩下较小的面积，没有开阔水面，所有地表水都覆盖有挺水植物，并且湿地范围内包含大量的灌木。上午，我们首先测定了湿地中心点的GPS坐标，然后沿湿地边界和各地表水区域进行了GPS的标记，绘出了湿地的大致地图。丁希若主要负责GPS的操作；邢悦婷拥有丰富的植物知识，主要进行植物的鉴定工作；刘齐、Leslie以及邢悦婷还拍摄了许多不错的照片。
在这一天中，我们在湿地里发现了各种蝴蝶和蜂类在内的多种昆虫，包括黑脉金斑蝶（Danaus plexippus）等，一些蛙类，如豹蛙（Lithobates pipiens），还看到了蛇，但是由于只看到了尾部并且很快逃走了，无法确定其确切的种类。
