An investigation of the ecological anomaly of the tundra of southern Newfoundland and ecosystem response to stress

标题：对位于纽芬兰最南端的冻土带进行调查，以及气候变化对这一独特系统的影响。从荷兰的圣约翰斯驱车向南行驶，可以看到北部针叶林的植被变化，直到在阿瓦隆半岛和伯林半岛的最南端，遇到的生态系统是北极冻土带。之所以出现冻土带到目前为止，并不是因为长时间的冰冻月份，而是因为强烈的雾气环境。这个冻土带上的一些地方一年中有超过半年的雾天，减少了传入的太阳辐射，提供了非常低的年度热量单位。冻土带很古老，据信可以追溯到冰川后更广阔的地区。包括驯鹿在内的动植物生活在这里。考虑到格陵兰冰盖的快速融化、径流的加速和冰山的加速崩解，沿着拉布拉多和纽芬兰海岸漂浮，雾是否有可能会增加，南部苔原气候将会退化？这项研究将检查当地的植被和土壤条件，寻找温室气体排放随时间的变化，并评估降温的可能性，这将给纽芬兰的土地和人民带来后果。

Title:An investigation of the tundra lying at the  southern end of Newfoundland  and the effect of climate change on this  unique systemAs one drives south from St Johns,Nfld  the vegetation changes from boreal forest  till, at the southern-most end of the Avalon and Burin peninsulas, the ecosystem encountered is arctic tundra.This appearance of tundra so far south is not  due to long frozen months but to the intensely foggy environbment. Some locations on this tundra have foggy days more than half of the year  cutting down incoming solar radiation and giving very low annual heat units.The tundra is ancient , believed to trace back to much more extensive areas in post glacial times.Plants and animals, including caribou live here. Given the rapid melting of the Greenland ice cap, accelerated  run-off and  accelerated calving of icebergs, floating down the Labrador and Newfoundland coast ,is it possible that the fogs will increase and  the southern tundra climate will detiorate? This study will examine the  vegetation and soil conditions, look for green house gas emission changes over time and assess the likelihood of cooling , with consequences for the land and people of Newfoundland.
