A study conducted between 2014 and 2018 reveals that a large proportion of the deltaic populations of Volta delta in Africa, the Ganges Brahmaputra Meghna delta in Bangladesh and India, and Mahanadi delta in India cited economic reasons as a cause of their migration and only 2.8% cited environment reasons. One third of migrant households ...

The Madagascan sunset moth ( Chrysiridia rhipheus ) has migrations of up to thousands of individuals, occurring between the eastern and western ranges of their host plant, when they become ...
This allows scientists to observe the difference between population variation, climate and well as the size and shape of the landscape. An example of the use of landscape genetics as a means to study seed dispersal, for example, involves studying the effects of traffic using motorway tunnels between inner cities and suburban area.
