Briefly, it is the result of a four years study by a research team, headed by Dr. Pauline Morris, principal lecturer in Sociology at the Borough Polytechnic, London, of the physical, psychological and sociological environment which institutions provide for the mentally handi...

To migrate, stay put, or wander? Varied movement strategies in bald eagles (Haliaeetus leucocephalus)

BACKGROUND Quantifying individual variability in movement behavior is critical to understanding population-level patterns in animals. Here, we explore intraspecific variation in movement strategies of bald eagles (Haliaeetus leucocephalus) in the north Pacific, where there is high spatiotemporal resource variability. We tracked 28 bald eagles (five immature, 23 adult) using GPS transmitters bet...

To move or not to move.

Semaphorins were discovered 11 years ago as molecular cues for axon guidance that are conserved from invertebrates to humans. More than 20 semaphorin genes have been identified in mammals and their protein products are now known to be involved in a range of processes from the guidance of cell migration to the regulation of the immune response, angiogenesis and cancer. Plexins, either alone or i...
