Now, a study suggests that rising temperatures will boost underground microbes (微生物) there to produce more carbon dioxide (CO_{2})——potentially creating a feedback loop that worsens climate change."The tundra is a sleepy biotome (生物群落)," says Sylvain Mac, an environmental scientist w...
How does climate change affect the tundra biome? Tundra biome The tundra biome is the coldest of all the forest regions. The region has a minimal amount of vegetation, with trees, in particular, being quite rare. The tundra biome also receives very little rainfall or precipitation, moulding th...
Climate-vegetation models predict rapid northward advance of the subarctic forest-tundra in the coming century, although modelled responses may not be congruent with field data. This study aimed to determine how forest-tundra vegetation has responded to climate change in north-central Canada. ...
is impacting fire worldwide. Results show that climate change is increasing burned area in most regions, particularly during periods of peak fire activity, and this effect is increasing over time. However, changes in population and land use are mitigating some of the effects of climate change. ...
Climate change is a pervasive threat to biodiversity. While range shifts are a known consequence of climate warming contributing to regional community change, less is known about how species’ positions shift within their climatic niches. Furthermore, wh
根据第一段this dramatic climate change is causing the warming up and melting of the Arctic,which has led to other potential dangers for nature there.剧烈的气候变化导致北极变暖和融化,这给那里的自然带来了其他潜在的危险。可知,全球变暖达到了灾难性的程度。A.Controllable可控的;B.Practical实际的;C....
Climate change is changing the migration (迁移) routes of animals worldwide, Here's alook at new research on how two species have been affected.First, mule deer(黑尾鹿). Every spring in Wyoming, vegetation frst appears at loweraltitudes before progressing up the mountainside. Migrating mule deer...
Human beings are among the least specialized of all animals and can live almost anywhere. Their clothes and their homes act as a sort of "miniature climate" that can be taken with them everywhere.According to the passage, plants on the tundra grow in the ground ___. A.to avoid being...
Both life‐history plasticity and local adaptation will shape range‐wide responses to climate warming in the tundra plant Silene acaulis 来自 Wiley 喜欢 0 阅读量: 52 作者:ML Peterson,DF Doak,WF Morris 摘要: Many predictions of how climate change will impact biodiversity have focused on range ...
These results have implications for global models of potential feedbacks on climate change inferred from changes in the carbon balance of northern wetlands and tundra. Firstly, because the decay potential of the organic matter varies locally as well as regionally, predictions of how the tundra carbon...
