A buttress on the need for welfare program in Nigeria and the important obligation to consider the Economics’and CIA’s contextual position for the dependency ratios,both total and elderly dependency ratio alongside the consideration of the age structure and demography statistics of Nigeria relatively to other economies,particularly as an elixir for the declining older population in Nigeria and the aged male contraction in the nation.Although,older female population is higher in every country as obtainable globally,the Nigerian case is that of drastic contraction in both aged male and older population generally.Therefore,the submission is that the government has to consider the total dependency ratio to the elderly dependency ratio,which is all-encompassing in order to cater for the declining older population and to appropriate the requisite welfare cum benefits programs in the nation. 展开更多

Livestock grazing has been demonstrated to affect the population abundance of small rodents in grasslands,but the causative mechanism of grazing on demographic parameters,particularly the age structure and sex ratio,is rarely investigated.In this study,we examined the effects of sheep grazing on the cohort structure and sex ratio of Brandt’s vole(Lasiopodomys brandtii)in Inner Mongolia of China by using large manipulative experimental enclosures during 2010-2013.Our results indicated that sheep grazing significantly decreased the proportion of the spring-born cohort,but increased the proportion of the summer-born cohort.Grazing increased the proportion of males in both spring and summer cohorts.In addition,we found a negative relation between population density and the proportion of the overwinter cohort.Our results suggest that a shift in the cohort structure and the sex ratio may be an important strategy for small rodents to adapt to changes in food resources resulting from livestock grazing. 展开更多
