Density-mediated carry-over effects explain variation in breeding output across time in a seasonal population.
In seasonal environments, where density dependence can operate throughout the annual cycle, vital rates are typically considered to be a function of the number of individuals at the beginning of each season. However, variation in density in the previous season could also cause surviving individuals to be in poor physiological condition, which could carry over to influence individual success in ...
متن کاملClimatic effects on breeding grounds are more important drivers of breeding phenology in migrant birds than carry-over effects from wintering grounds.
Long-distance migrants may be particularly vulnerable to climate change on both wintering and breeding grounds. However, the relative importance of climatic variables at different stages of the annual cycle is poorly understood, even in well-studied Palaearctic migrant species. Using a national dataset spanning 46 years, we investigate the impact of wintering ground precipitation and breeding g...
متن کاملOn optimal cross-over designs when carry-over effects are proportional to direct effects
There are a number of different models for cross-over designs which take account of carry-over effects. Since it seems plausible that a treatment with a large direct effect should generally have a larger carry-over effect, Kempton, Ferris and David (2001) considered a model where the carry-over effects are proportional to the direct effects. The advantage of this model lies in the fact that the...
متن کاملCarry-over effects in a Pacific seabird: stable isotope evidence that pre-breeding diet quality influences reproductive success.
1. Understanding the interactions between different periods of the annual cycle in migratory animals has been constrained by our inability to track individuals across seasons. In seabirds, virtually nothing is known about how diet quality during the non-breeding period, away from the breeding grounds, might influence subsequent reproductive success. 2. We used stable nitrogen (delta(15)N) and c...
متن کاملEnvironmental Conditions during Breeding Modify the Strength of Mass-Dependent Carry-Over Effects in a Migratory Bird
In many animals, processes occurring in one season carry over to influence reproductive success and survival in future seasons. The strength of such carry-over effects is unlikely to be uniform across years, yet our understanding of the processes that are capable of modifying their strength remains limited. Here we show that female light-bellied Brent geese with higher body mass prior to spring...
