Migration Routes Change

Individuality in bird migration: routes and timing.

The exploration of animal migration has entered a new era with individual-based tracking during multiple years. Here, we investigated repeated migratory journeys of a long-distance migrating bird, the marsh harrier Circus aeruginosus, in order to analyse the variation within and between individuals with respect to routes and timing. We found that there was a stronger individual repeatability in...

Blockage of migration routes by dam construction: can migratory fish find alternative routes?

The present study explored the interaction between the upriver migration of fish and the blockage of their migration routes by dam construction. Specifically, we studied (i) the capacity of migratory fish to locate alternative routes in the presence of an obstacle, and (ii) the behavior of the fish after they were artificially transferred to the reservoir. With the use of the markrecapture tech...

Migration and environmental change

In recent years, there has been considerable speculation about the possible effects of climate change on migration, especially in developing countries. Stern (2006) noted that 200 million people worldwide live in at-risk coastal flood plains, which would be threatened by changes in sea-level. Moreover climate change may lead to resource scarcity, drought, floods, and other environmental changes...
