Breeding phenology and winter activity predict subsequent breeding success in a trans-global migratory seabird.
Inter-seasonal events are believed to connect and affect reproductive performance (RP) in animals. However, much remains unknown about such carry-over effects (COEs), in particular how behaviour patterns during highly mobile life-history stages, such as migration, affect RP. To address this question, we measured at-sea behaviour in a long-lived migratory seabird, the Manx shearwater (Puffinus p...
متن کاملInterspecific synchrony of seabird population growth rate and breeding success
Environmental variability can destabilize communities by causing correlated interspecific fluctuations that weaken the portfolio effect, yet evidence of such a mechanism is rare in natural systems. Here, we ask whether the population dynamics of similar sympatric species of a seabird breeding community are synchronized, and if these species have similar exceptional responses to environmental va...
متن کاملMatches and mismatches: ocean climate, prey phenology and breeding success in a zooplanktivorous seabird
In the marine environment, climatic changes are asymmetrically altering the phenologies of species at different trophic levels, causing an increase in the severity of mismatching between predators and their prey. At Triangle Island (British Columbia, Canada), the zooplanktivorous seabird Cassin’s auklet Ptychoramphus aleuticus breeds less successfully in warm-water years than in coldwater years...
متن کاملConsequences of recruitment decisions and heterogeneity on age-specific breeding success in a long-lived seabird.
An individual's age at first reproduction and investment in successive reproductive attempts are involved in mechanisms that can impede somatic repair, resulting in a decline in reproductive abilities with age (reproductive senescence). We used long-term data from the Black-legged Kittiwake, a long-lived seabird, to address the relationship between recruitment age, age-specific breeding success...
متن کاملDrivers of Time-Activity Budget Variability during Breeding in a Pelagic Seabird
During breeding, animal behaviour is particularly sensitive to environmental and food resource availability. Additionally, factors such as sex, body condition, and offspring developmental stage can influence behaviour. Amongst seabirds, behaviour is generally predictably affected by local foraging conditions and has therefore been suggested as a potentially useful proxy to indicate prey state. ...
