1·The idea worked, and it has dramatically reduced the time (to less than an hour) and expense (to less than $2) of using DNA to identify species.
此法收效甚好，极大地减少了用DNA确定物种的时间（少于一小时）和费用（两美元以内）。
2·An international team of scientists has agreed on a standard "DNA barcode" for plants that will allow botanists to identify species quickly and easily.
一组国际科学家为植物制定了统一的“DNA条码”，这将帮助植物学家更快、更简单地区分物种。
3·An international team of scientists has a GREed on a standard "DNA barcode" for plants that will allow botanists to identify species quickly and easily.
一组国际科学家为植物制定了统一的“DNA条码”，这将帮助植物学家更快、更简单地区分物种。
4·Because evidence sent to the lab rarely contains easily recognizable parts, much less a whole animal, the scientists must work to identify species from limited fragments.
因为被送到实验室的证物很难保存易于辨认的部位，更不可能是整只动物，科学家们必须从一些碎片中辨认物种。
5·Barcoding is a technique in which one or more short gene sequences, taken from a well-characterized portion of the genome, are used to identify a species through DNA analysis.
测序是一种技术，它是从具有明确特征的基因组提取的一个或多个短基因序列，并通过 DNA 分析来识别一个物种。
6·These species use echolocation to find their way and identify food.
这些物种利用回声定位来寻找方向并识别食物。
7·I know of scientists who conduct marine life surveys and identify new species every time they go out on a dive.
我知道有科学家在从事海洋生物调查，并在每次潜水时都能发现新的物种。
8·Studies should identify local mosquito species that play a role in WNV transmission, including those that might serve as a “bridge” from birds to human beings.
研究应确定当地传播西尼罗河病毒的蚊子种类，包括可能“桥接”鸟类和人类的蚊子。
9·Researchers continuously study specimens and identify them, all the while hunting for new species.
研究者在不断研究和辨认标本的同时，还在发掘新物种。
10·Users snap photos of local birds, plants, trees, and other species, and can either identify the organism or leave the classification up to the crowd.
用户可以拍下当地鸟类、植物、树木和其他生物的照片，然后对该生物进行鉴别，或者把鉴定工作留给其他人完成。
