Cím:	Information acquisition during migration: A social perspective / Zoltán Németh, Frank R. Moore
Dátum:	2014
ISSN:	0004-8038
Megjegyzések:	Information can enhance fitness, and the ways in which organisms acquire and use information are of heightened interest in ecological studies today. Migratory birds, as long-distance travelers of the globe, depend on rapid access to accurate information and thus provide particularly interesting study subjects for cognitive ecology. Yet, questions regarding how migratory birds collect information and make decisions en route remain to be answered. Here, we review the current status of this field of study and focus our attention on social learning (broadly defined as the use of inadvertently produced social information) as an important cognitive mechanism that can operate across taxonomic boundaries. We argue that social learning is critical to accelerate resource acquisition while reducing risks and uncertainties during migration. We put forward eight testable predictions in relation to when increased use of social information might be expected. Finally, we argue that migrant communities at stopover sites may serve as additional sources of information where transient associations with others may have important and long-lasting benefits

Cím:	Seasonal variation in CREB expression in the hippocampal formation of first-year migratory songbirds: Implications for the role of memory during migration / Németh Zoltán, Luo Yuan, Owen Jennifer C., Moore Frank R.
Dátum:	2017
ISSN:	0004-8038
Megjegyzések:	Information is key to successful migration. Yet, how much information is learned and stored over the course of migration relative to other phases of the annual cycle is still unknown. We assessed seasonal variation in long-term memory formation indirectly by measuring the expression of cAMP response element binding protein (CREB) in hippocampal samples collected from migratory songbirds, Veery (Catharus fuscescens) and Wood Thrush (Hylocichla mustelina) at different life-history events (fall stopover, spring stopover, breeding season) during their first year of life. Consistent with our prediction, CREB expression was low during autumn (first) migration relative to levels in conspecifics during the first breeding season. These results suggest that young migratory birds may store relatively little spatial information during migration, particularly until they reach their wintering area and their global navigational map is more fully developed.
