In order to simulate the evolution of population geography of China during the past 2000 years, an agent-based model is presented in this paper. In the model, population individuals are denoted as agents and geographical environment is presented by cellular automata. Agents can migrate or settle ...
Here, we studied the spatio-temporal relationship between human populations and water resources in the conterminous US for the decades 1790–2010 (excluding 1960, for which population data are lacking)24. During this time, large migrations of primarily European settlers gradually expanded from the Atl...

specialization and economy scale significantly contributed to improve urban economic efficiency.When the level of population urbanization increases,the combined effects of specialization increases,while the combined effect of economy scale decreases.Sub-regional comparative studies also reached to the similar ...
Variation in space will favor the emigration of a small fraction of the population, while variation in time will favor the emigration of a larger fraction. 展开 关键词: plant ecology, phytogeography DOI: 10.2307/1934583 被引量: 770 年份: 1971 ...
The nutrient-rich tubers of the greater yam, Dioscorea alata L., provide food and income security for millions of people around the world. Despite its global importance, however, greater yam remains an orphan crop. Here, we address this resource gap by p
The prevalence of causative agents of tinea capitis is not only related to geography but also to socioeconomic factors. Multiple factors have to be considered for the management for control of this disease. 展开 关键词: Tinea capitis epidemiology aetiology organisation and administration prevention and...

Reduction in N has possibly been further compounded by population fragmentation and the subsequent accumulation of deleterious mutations, thus pushing mangroves even closer to extinction. Crucially, the impact of the next SLR will be exacerbated by human encroachment into these mangrove habitats, ...
