Possible linkage between neuronal recruitment and flight distance in migratory birds.

摘要: New neuronal recruitment in an adult animal’s brain is presumed to contribute plasticity and increase the ability contend with new changing environments. During long-distance migration, birds migrating greater distances are exposed more diverse spatial information. Thus, we hypothesized that migration distance would correlate of neurons into regions involved migratory navigation. We tested this hypothesis on two Palearctic migrants - reed warblers (Acrocephalus scirpaceus) turtle doves (Streptopelia turtur), caught Israel while returning from Africa spring summer. Birds were injected a birth marker later inspected for known play role navigation hippocampus nidopallium caudolateral. calculated each individual by matching feather isotopic values (δ2H δ13C) winter base-maps these isotopes Africa. Our findings suggest positive correlation between caudolateral doves. This multidisciplinary approach provides insights avian adapt different challenges.
