Migrant residential patterns are a major influence on urban development. Since the restrictions on temporary migration to China’s cities were formally lifted in 1983, there have been massive waves of internal migration from rural to urban areas. Given the persistence of the country’s migration trends, it is important to explore whether residential patterns of temporary migrants in China’s citie...

A methodology for identifying key structures in migration flow tables is presented in this chapter. The tables contain flows of persons cross-classified by origin, destination and some other characteristic, such as age or ethnicity. This work is important for both understanding aggregate migration patterns in general and for estimating flows in the context of incomplete migration data. The rese...

BACKGROUND Altitudinal migration systems are poorly understood. Recent advances in animal telemetry which enables tracking of migrants across their annual cycles will help illustrate unknown migration patterns and test existing hypotheses. Using telemetry, we show the existence of a complex partial altitudinal migration system in the Himalayas and discuss our findings to help better understand ...

One of the central problems in migration measurement arises as a consequence of the different sources of migration data. Most information regarding migration is obtained from population censuses or population registers that report migration data for a given time interval. Another source of migration data is the sample survey which may be designed to provide information about both migrants and...

Along with the flows of China’s foreign direct investment following the newly implemented ‘One Belt, One Road’ strategy by the Chinese government will likely generate movements of state employees, entrepreneurs, workers and accompanying family members to respective countries along the Belt and Road. It is not clear how large Chinese migration flows into these countries will be, who they are, ho...

We developed a dynamic state variable model of individual migrating shorebirds for use in testing hypotheses about spring migration strategies of the Pectoral Sandpiper Calidris melanotos. We conducted model sensitivity analyses to determine how predicted migration schedules might vary with respect to the landscape and the physical environment. In landscapes with closely spaced, high-quality st...

This article "is devoted to the international migration issue in the Czech Republic and Slovakia (Czechoslovakia). Besides the contemporary trends, the international migration situation is briefly traced back to the communist era. The probable future scenario of international migration development--based especially on migration patterns that Western Europe has experienced--is also sketched, w...

The existence, uniqueness, and shape of clines in a quantitative trait under selection toward a spatially varying optimum is studied. The focus is on deterministic diploid two-locus n-deme models subject to various migration patterns and selection scenarios. Migration patterns may exhibit isolation by distance, as in the stepping-stone model, or random dispersal, as in the island model. The phe...

Riparian forest vegetation is widely believed to protect riverbanks from erosion, but few studies have quantified the effect of riparian vegetation removal on rates of river channel migration. Measured historical changes in a river channel centreline, combined with mapped changes in floodplain vegetation, provide an opportunity to test how riparian vegetation cover affects the erodibility of ri...

"This essay discusses trends and patterns in migration from Turkey to Arab countries since the late 1960s. It relates this migratory movement to the wider context of Turkish emigration. By examining the ongoing migration ties between Turkey and the receiving Arab countries, the paper concludes with a discussion of likely migration flows and their implications." (EXCERPT)
