Citizen Scientists Understanding how nature responds to climate change will require monitoring key life cycle1 events-flowering, the appearance of leaves, the first frog calls of the spring - all around the world. But ecologists cant be everywhere so theyre turning to non-scientists, sometimes called citizen scientists, for help. A group of scientists and educators launched an organization last year called the National Pheonology4 Network. Phenology is what scientists call the study of the timing of events in nature. People dont have to be plant experts -they just have to look around and see whats in their neighborhood, says Jennifer Schwartz, an education consultant with the project. As we collect this data, well be able to make an estimate of how plants and eommunities5 of plants and animals will respond as the climate changes. Frog n. 蛙 Ecologist n.生态学家 Phenology n.物候学 Bud v.发芽,萌芽;n.芽,花蕾 Professional adj.专业的,职业的;n.职业选手,专业人员 1. life cycle:生命周期,即生物发展过程的系列变化。 3. data 是复数形式,但常用做单数,所以这里的代词是it。另参见最后一段As we collect this data, ...。这里的data 也用作单数。 5. communities:生态学词汇:生物群落,记载比较相似的环境条件下在特定自然区域或环境中生活和互相影响的一群植物和动物。 A) to provide their personal life cycles.
