  Climate variability, fishing and predation are the main factors affecting fish population dynamics. In this study, the drivers of population growth variability were investigated for 7 fish stocks (2 cod, 4 herring and 1 mackerel stock) in the Gulf of St. Lawrence (NW Atlantic). The annual population growth sensitivity to both recruitment and survival (i.e. how much population growth depends on recruitment and survival) was estimated through elasticity analyses before being linked to harvesting history as well as environmental conditions (climate and predation). Stock-specific generalized additive models showed that population growth was most sensitive to recruitment variability with decreasing fish generation time, increasing water temperature and, in some cases, with predation. The dependence of population growth on recruitment, however, was generally close to 0, albeit higher for pelagic stocks than for demersal ones. This indicates that adult survival was more important than recruitment in shaping population growth and thus population size. As climate mainly acts on recruitment while fishing affects adult survival, management efforts seem more important than climate variability in regulating population growth, especially for long-lived cod. Nevertheless, population growth may become increasingly dependent on recruitment variability with warming waters; therefore, more flexible management strategies should be developed to cope with these oscillations.

  For long-distance migrations to pay off for individual fish, the energetic costs must be counterbalanced by benefits. Understanding the fitness trade-offs associated with migration is essential for our ability to sustainably manage migratory species. Here, we investigated such trade-offs associated with the spawning migration of Northeast Arctic cod Gadus morhua, a stock of high historical and commercial value known to be able to migrate more than 1000 km southward to reach suitable spawning grounds. Reaching the more distant spawning grounds requires more energy and hence leaves less energy available for processes such as egg production. Previous studies have indicated that increased larval survival (e.g. from rapid early development in warmer southern waters) may offset the parental costs of migration. However, it was suggested that spatial variability in survival of early life stages might cancel out this survival benefit. As an alternative, we ask if the fitness benefit of long-distance migration may reside in increased offspring growth. Using an integral projection model incorporating effects of body length and migration distance, we quantified the increase in offspring growth needed to offset parental costs of long-distance migration on fitness. Our results suggest that a 12.5% length in crease of juvenile cod is required to offset parental costs of long-distance migration. This is within the estimated growth benefit of 20% suggested by drift models of early life stages of cod. These results highlight the potential importance of offspring growth as another factor explaining the benefit of long distance migration, broadening our knowledge on spawning migration.

  We used a comparative approach investigating commercially fished species with contrasting life histories and trophic positions in an Arcto-boreal system, the Barents Sea. Our objective was to address the ecological consequences of harvesting on stock properties (stochastic growth rate; a property related to intrinsic growth rate) in relation to different external conditions (fishing pressure and climate). We used age-structured population matrices to calculate the transient elasticity of population growth with respect to recruitment (how much population growth depends on recruitment) over time. Using a generalized additive model (GAM) analysis, we found that the transient elasticity of population growth to recruitment overall depends mostly on age structure (which in turn is affected by fishing) but also on climate (temperature change or winter North Atlantic Oscillation). Our results indicate that under warmer conditions, population growth of high latitude stocks becomes increasingly dependent on recruitment, which makes the stocks more difficult to manage. In general, there was no effect of ongoing fishing pressure on elasticity after age structure had been taken into account, supporting the view that long-term fishing pressure affects the susceptibility of the population to climate indirectly, by changing the age structure of the stock. However, for most of the stocks we have studied here, populations have low elasticity to recruitment due to their life history, meaning that the health of the stock mainly depends on survival after the recruitment stage; i.e. fisheries management is more important than climate.

  To investigate laying decision and clutch size determination in indeterminate layers, we analysed in-nest activity (nest presence, and copulation, prey deliveries, and entrance frequencies) and female body mass change, as well as their relation to clutch size variation in five Barn Owl pairs (Tyto alba) nesting in eastern France. Body mass of the female and behaviour [copulation frequency, entrance frequency, and prey delivery to the nest by the male (in number and mass)] were monitored using an automated weighing system and a video camera. There was a consistent change of behaviour and foraging activity among pairs ca. 18 days before laying indicating that the females may be tied to the nest at this time. Barn Owls being indeterminate layers have their clutch size determined at the oviposition of the first egg of the clutch. Window correlation analyses between the clutch size and the female body mass gain indicate that the clutch size might be determined no later than a few days before the laying of the first egg. Our results suggest that female Barn Owls may use the pre-laying period to determine the clutch size using cues such as the male food deliveries (a proxy for male quality).

  The behavioural responses of barn owl Tyto alba chicks to variation of ambient temperature were investigated in relation to hatching order. Four broods of wild barn owls were videomonitored during their postnatal growth. During the foraging trips of the adults, nest temperature and the behaviour of the chicks were recorded. The results show an influence of hatching order on the individual behavioural responses to variation in ambient temperature. The average temperatures at which the chicks showed specific thermal behavioural responses depend on the position in the size hierarchy. This result may indicate a difference in development among siblings in relation to the hatching order, possibly due to a difference in growth or tissue maturation associated with differences in food availability. That latehatched chicks showed behavioural responses against cold and heat stress respectively at higher and lower temperature than their older siblings may be, in addition to being a consequence of food restriction, a way to divert part of their energy intake from muscle maturation to growth.

  The Barents Sea is a shelf sea sustaining a highly productive ecosystem including several commercially important fish stocks among which the Northeast Arctic (NEA) cod (Gadus morhua), Norwegian Spring Spawning (NSS) herring (Clupea harengus) and the Barents Sea (BS) capelin (Mallotus villosus) are key fish species in this ecosytem. NSS herring is currently one of the largest herring stocks in the world, and it is both an important prey (for e.g. cod and marine mammals) and predator species (for e.g. planktonic early life stages of fish and zooplankton). It spawns in the Norwegian Sea in February-March and deposits eggs on the sea bottom. After hatching, larvae and 0-group appear in the upper water layer and drift by the coastal current to enter the Barents Sea where they spend their first 3 to 4 years of life before migrating to the north Atlantic as adult. It is during its juvenile life stage that the herring is susceptible to predation by the large stock of NEA cod. Here, we develop a state-space model to estimate the effect of cod predation on young herring mortality. We used the obtained estimates to quantify at the population level the joint effect of fishing and cod predation on young herring. Our results indicate a significant effect of cod and illustrate how management of NSS herring benefits from jointly considering cod and fishing.
