Absolute Population Estimates using Marking Techniques,may be estimated (Le Cren, 1965). This was based on the principle that if a proportion of the population was marked in some way, returned to the original population and then, after complete mixing, a second sample was taken, the number of marked individuals in the second sample would have the same r作者: candle 時間: 2025-3-22 05:40 作者: 慢跑鞋 時間: 2025-3-22 10:01 作者: CRUE 時間: 2025-3-22 13:27 作者: CRUE 時間: 2025-3-22 18:28 作者: 噱頭 時間: 2025-3-23 01:05 作者: 反話 時間: 2025-3-23 01:42 作者: maudtin 時間: 2025-3-23 06:44
