I'm here to tell you the population of Earth is a lot like those stars. In parts of the globe, the human population is already, or will soon be, shrinking. I know what you're thinking. And yes, total population is still growing from eight billion today to a peak of probably nine ...
1b) (see Methods) in order to examine the temporal trends of human population distribution across different distance classes to major rivers and among distinct types of aquifers. We used the relationship between normalized population density (NPD) and distance to major rivers (DMR) to indicate ...

Many studies of anthropological genetics have focused on population structure (deviations from panmixia due to population subdivision, particularly due to ...

The world population is expected to increase greatly this century, aggravating current problems related to climate, health, food security, biodiversity, energy and other vital resources. Population growth depends strongly on total fertility rate (TFR), b
World Population his famous 1798 Essay on the Principle of Population, Malthus argued that human populations tend to grow exponentially, while food production is limited by land available for agriculture. In short, human populations tend to increase faster than food supply, leading to an imbalance...
The Urbanization of the Human Population 来自 ResearchGate 喜欢 0 阅读量: 367 作者: K Davis 摘要: The urbanized societies of today not only have urban agglomerations of a size never before attained but also have a high proportion of their population concentrated in such agglomerations. Between ...
Our results suggest that there is currently no evidence for a persistent through-time relationship between human and megafauna population levels in North America. There is, however, evidence that decreases in global temperature correlated with megafauna population declines....
The rate of cuckoldry in this Western population was 0.9% (95% confidence interval 0.4–1.5%), and we argue that given the current data on historical populations we have to conclude that, at least for Western human populations, cuckoldry rate is probably in the range of 1%. Heredity (...
