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...
متن کاملBlockage 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...
متن کاملAlternative migration routes of Ascaris suum in the pig.
Experiments were conducted to investigate possible alternative routes of extraintestinal migration of Ascaris suum larvae in the pig. Pigs were infected with A. suum via injection of newly hatched larvae into cecal veins (i.v.), into cecal lymph nodes (LN), or intraperitoneally (i.p.), and control animals were inoculated orally with infective eggs (p.o.). Two pigs per inoculation route were nec...
متن کاملAll across Africa: highly individual migration routes of Eleonora's falcon.
Eleonora's falcon (Falco eleonorae) is a rare raptor species that delays its breeding period until late summer to feed its young with passerines at the peak of autumn migration. Since the 1950s, this slender winged falcon has been believed to migrate along a historical route via the Red Sea to its main wintering area in Madagascar. In our study, we used satellite telemetry to investigate the re...
متن کاملMigration 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...
