Evolution of the hormonal control of animal performance: Insights from the seaward migration of salmon.
The endocrine system is the key mediator of environmental and developmental (internal) information, and is likely to be involved in altering the performance of animals when selection has favored phenotypic plasticity. The endocrine control of performance should be especially pronounced in animals that undergo a developmental shift in niche, such as occurs in migratory species. By way of example...
متن کاملAnimal Navigation: Salmon Track Magnetic Variation
How animals navigate long distances to specific targets remains enigmatic. For Pacific salmon, new evidence suggests fish imprint on the magnetic coordinates of their home river and use this information to guide their return from distant open-ocean feeding areas.
متن کاملMovement, migration, and smolting of Atlantic salmon (Salmo salar)
A variety of movements characterize the behavioral plasticity of Atlantic salmon (Salmo salar) in fresh water, including movements of fry from redds, establishment of feeding territories, spawning movements of sexually mature male parr, movement to and from winter habitat, and smolt migration in spring. Smolting is an adaptive specialization for downstream migration, seawater entry, and marine ...
متن کاملPhysiological Mechanisms of Imprinting and Homing Migration of Pacific Salmon
© 2016 TERRAPUB, Tokyo. All rights reserved. doi:10.5047/absm.2016.00901.0001 pink salmon are phylogenetically the most advanced salmon species, while masu salmon are considered to be the more primitive species (Murata et al. 1996). Pink salmon are also the most widely distributed species and have the largest population size, while masu salmon appear to have the most restricted distribution and...
متن کاملConservation physiology of animal migration
Migration is a widespread phenomenon among many taxa. This complex behaviour enables animals to exploit many temporally productive and spatially discrete habitats to accrue various fitness benefits (e.g. growth, reproduction, predator avoidance). Human activities and global environmental change represent potential threats to migrating animals (from individuals to species), and research is under...
