DNA in Water Could Help Estimate Population Sizes
- "River water, lake water, and seawater contain DNA belonging to organisms such as animals and plants. Ecologists have begun to actively analyze such DNA molecules, called environmental DNA, to assess the distribution of macro-organisms. ... A case study conducted in Maizuru Bay, Japan, confirmed that the estimate of the population abundance of Japanese jack mackerel (Trachurus japonicus), obtained by the proposed method, was comparable to that of a quantitative echo sounder method." - Excerpt from NIES Japan
