August 23rd Elbow Lake and other activities.
饥肠辘辘的我们终于得晚饭前回到了大本营，丰富的晚餐让每个人都十分满足。饭后是王老师给我们带来了“Thoughts for fish,water and environment？”，以亚马逊流域和西藏地区为例进行详细的介绍。之后依然是“美丽中国”纪录片，今天是西藏篇，这一集是BBC邀请王老师作为科学顾问共同拍摄完成的。在这集的介绍中，我们领略到了西藏的文化的魅力以及当地人与生态环境的和谐相处。
A nasty raining day, but still we put on our water-proof coats, even rain coat and brought plenty of water and food. We headed out to our hiking destination: Elbow Lake, which used to be a resort of HP and became part of QUBS not long ago.
Isolated with other lakes, Elbow Lake is not invaded by any kind of exotic species, such as zebra mussels, which guarantees its high scientific research value.
In the guidance of Steve Lougheed, we walked along the lake, went across bushes, until we arrived a pond made by beavers. They built the dam using wood and bushes, mud and leaves. With the help of water flow, the dam is strong enough to block the water flow and raise water level so that they can build beaver houses in the middle of the wetland. Safe and comfortable, they really know how to enjoy life, don’t they? And they also help the formation of wetland in the mean time which benefits a lot to other animals and plants, and themselves, as long as they don’t hit themselves when cutting down a tree.
Steve is also doing a very interesting research in these wetlands. He is monitoring the temperature and humidity of the microclimate of some chosen wetlands, the most important, the calling time and pattern of different kinds of frogs. The inspiration came from an exist research about the relationship between frog breeding season and climate change. Some frog species may not be able to deal with climate change which will be reflected on their population and other aspects. It is a 20 years research; hopefully, we will know what’s happening 17 years later.
We could still find a lot of interesting creatures in a raining day, like fungi, moss, lichen, birds and amphibians. But we were supposed to be able to find lizards in a sunny day when they come out for sun bath.
We ate sandwiches, cookies, peanuts and grapes in a beautiful cabin near the lake. Yuxiang and Mingzhi wouldn’t tell us the schedule for afternoon. It sounded like they had a big surprise for us, which did surprise us a lot when we woke up on the van and found ourselves in front of a big shopping mall. None of us expected to go shopping in the morning, let alone being wise enough to bring any money, even credit card. Yuxiang helped us again, generously.
Nothing is better than yummy dinner in QUBS. Yuxiang gave us a lecture about his major research on comparative physiology and fish adaptation, named Thoughts for Fish, Water and Environment. He talked about Pirarucu, a large air-breathing fish and Oscar, low oxygen tolerant fish, and other weird fishes living in the Amazon, and also scale-less carp living in Qinghai Lake, Tibet. After the lecture, Yuxiang was proud to show us the documentary Wild China: Tibet, which he was invited to help filming.
