Citizen Scientists

　　Understanding how nature responds to climate change will require monitoring key life cycle events — flowering, the appearance of leaves, the first frog calls of the spring — all around the world. But ecologists can't be(           51) so they're turning to non-scientists, sometimes called citizen scientists, for help.

　　Climate scientists are not present everywhere.(           52) there are so many places in the world and not enough scientists to observe all of them, they're asking for your help in(           53) signs of climate change across the world. The citizen scientist movement encourages(           54) people to observe a very specific research interest — birds, trees, flowers budding, etc. — and send their observations(           55) a giant database to be observed by professional scientists. This helps a small number of scientists track a(           56) amount of data that they would never be able to gather on their own.(           57) like citizen journalists helping large publications cover a hyper-local beat, citizen scientists are ready for the conditions where they live.(           58) that's needed to become one is a few minutes each day or each week to gather data and (           59) it in.

　　A　group of scientists and educators launched an organization last year(           60) the National Phenology(生物气候学) Network. "Phenology" is what scientists call the study of the timing of events in nature.

　　One of the group's first efforts relies on scientists and non-scientists (           61)to collect data about plant flowering and leafing every year. The program, called Project Bud Burst, collects life cycle(62) on a variety of common plants from across the United States. People participating in the project — which is (           63) to everyone — record their observations on the Project Bud Burst website.

　　"People don't (           64) to be plant experts — they just have to look around and see what's in their neighborhood," says Jennifer Schwartz, an education consultant with the project. "As we collect this data, we'll be able to make an estimate of (           65) plants and communities of plants and animals will respond as the climate changes."
