Abstract

Sibly et al.'s (Reports, 22 July 2005, p. 607) contention that density dependence acts strongly on low-density animal populations irrespective of body size contradicts many long-term studies of large mammals. Their findings were distorted by harvest records, which may poorly reflect population trend. Omitting unreliable data, their massive data set is reduced to only one case for large mammals.

摘要

西布利等人（《报告》，2005年7月22日，第607页）认为，无论体型大小，密度制约对低密度动物种群都有强烈影响，这一观点与许多对大型哺乳动物的长期研究相矛盾。他们的研究结果被捕猎记录扭曲了，捕猎记录可能无法很好地反映种群趋势。剔除不可靠的数据后，他们庞大的数据集对于大型哺乳动物来说只剩下一个案例。
