“…We see evidence of animal migratory culture [87,91,96] and experiments suggest that it can even exhibit cumulative improvement in efficiency over time [94], but can we find evidence for such cumulative navigational culture in natural populations? Furthermore, in line with widely used definitions of cumulative culture (e.g.…”

“…Although subsequent generations learning from older individuals was not directly tested, the phenomenon could be reasonably inferred from the data. Similarly, for Atlantic herring, genetic or environmental factors do not explain well this species' annual return to specific sites to feed and breed, leaving social learning, where young individuals school with and learn from older and more experienced individuals, as the most likely explanation [87,98]. Results from studies of lightbellied brent geese (Branta bernicla hrota) show that most offspring chose staging and wintering sites in adulthood that were identical or very near to those of their parents, suggesting an important role of social learning of migratory routes, as limited genetic differences between migrants from different routes was observed [89].…”

Animals often travel in groups, and their navigational decisions can be influenced by social interactions. Both theory and empirical observations suggest that such collective navigation can result in individuals improving their ability to find their way and could be one of the key benefits of sociality for these species. Here, we provide an overview of the potential mechanisms underlying collective navigation, review the known, and supposed, empirical evidence for such behaviour and highlight interesting directions for future research. We further explore how both social and collective learning during group navigation could lead to the accumulation of knowledge at the population level, resulting in the emergence of migratory culture.This article is part of the theme issue ‘Collective movement ecology’.

“…The locations for the mixed aggregations are indicated by stars, solid stars ( 2002 need to delineate extant patterns of within-species genetic diversity and to use such knowledge to quantify the relative contributions of population components to mixed fisheries. This need applies to marine fishes in general, but particularly to species such as herring, which in the past have exhibited large and persistent local spawning aggregations supporting human communities entirely dependent on their fishery (Alheit & Hagen 1997), and for which local extinction/recolonization events are well documented for at least the last century (Corten 2002).…”

The existence of biologically differentiated populations has been credited with a major role in conferring sustainability and in buffering overall productivity of anadromous fish population complexes where evidence for spatial structure is uncontroversial. Here, we describe evidence of correlated genetic and life history (spawning season linked to spawning location) differentiation in an abundant and highly migratory pelagic fish, Atlantic herring, Clupea harengus, in the North Sea (NS) and adjacent areas. The existence of genetically and phenotypically diverse stocks in this region despite intense seasonal mixing strongly implicates natal homing in this species. Based on information from genetic markers and otolith morphology, we estimate the proportional contribution by NS, Skagerrak (SKG) and Kattegat and western Baltic (WBS) fish to mixed aggregations targeted by the NS fishery. We use these estimates to identify spatial and temporal differences in life history (migratory behaviour) and habitat use among genetically differentiated migratory populations that mix seasonally. Our study suggests the existence of more complex patterns of intraspecific diversity than was previously recognized. Sustainability may be compromised if such complex patterns are reduced through generalized management (e.g. area closures) that overlooks population differences in spatial use throughout the life cycle.

“…In this way, successful year classes can expand the bounds of their local population, both spatially (over spawning areas) and temporally (over spawning seasons). Recruited herring may successfully reproduce in a spawning season other than their own by learning to find the spawning grounds from the adult members of the adopted population (McQuinn 1997b;Slotte 1999bSlotte , 2001Corten 2001;Huse et al 2002). Year class twinning in herring was first reported in Icelandic waters by Einarsson (1952).…”

Mixing of populations or year class twinning in Norwegian spring spawning herring?

In the present study, we question whether the mixing of autumn spawning herring with Norwegian spring spawning herring (Clupea harengus L.) in feeding and wintering areas is a result of year class twinning, that is, that they hatched in spring as products of the spring spawning stock, but ended up spawning in autumn. The otolith microstructure of the summer feeding autumn spawners (July 2001) was similar to the wintering autumn spawners (January 2002), stable and low in comparison with the sympatric spring spawners caught in the same two seasons. Hence, the otolith microstructure of the analysed larval herring seemed representative of their own spawning season. Data from 1982 to 2003 demonstrated that the fraction of autumn spawners by year class has been quite low at 1-14%, but relatively high in some of the weak year classes, indicating a different recruitment success between the spawning groups. Length at age and somatic weight at length did not differ between the spawning groups. In comparison, the neighbour North Sea autumn spawning herring were significantly smaller at the same age.
