Atkinson 2011 finds a significant positive correlation between population size and phoneme inventory size (confirming Hay & Bauer 2007) and explains it by migration: phoneme sizes are largest in Africa, and as societies spread out of Africa and around the world they went through population and cultural bottlenecks and underwent phonological simplification as a consequence. We believe the correl...

The effective population size is required to predict the rate of inbreeding and loss of genetic variation in wildlife. Since only census population size is normally available, it is critical to know the ratio of effective to actual population size (NJN). Published estimates of NJN (192 from 102 species) were analysed to identify major variables affecting the ratio, and to obtain a comprehensive...

population management of exploited species requires information on absolute density and abundance through reliable survey methods. the baseline information is further needed for population dynamics studies and determination of conservation status. the current population size of pheasant is totally unknown, because there is no official attempt to estimate population size in previous years. in th...
