“…Powerful approaches exist, in particular manipulative experiments (Studds & Marra 2005, Legagneux et al 2012, Catry et al 2013, Schultner et al 2014 or long-term longitudinal measurements whereby individuals act as their own controls (Daunt et al 2014). Our approach to investigating the temporal structure in the strength of carry-over effects at multiple colonies provides an additional method of distinguishing be tween genuine carry-over effects and crossseasonal correlations (our third hypothesis).…”

“…Quantifying the relative importance of extrinsic and intrinsic effects has proved challenging in correlative studies, since they are confounded (individuals may vary both in performance and environments experienced). Two approaches have been used to date to tease apart these effects: experimental manipulation in one season as a causal test of carry-over effects (Studds & Marra 2005, Legagneux et al 2012, Catry et al 2013, Schultner et al 2014) and longitudinal measurements in individuals across a range of environmental conditions whereby they act as their own controls (Daunt et al 2014). Studies that investigate the temporal structure in the strength of seasonal interactions in multiple populations provide a third option.…”

Carry-over effects, whereby events in one season have consequences in subsequent seasons, have important demographic implications. Although most studies examine carry-over effects across 2 seasons in single populations, the effects may persist beyond the following season and vary across a species' range. To assess potential carry-over effects across the annual cycle and among populations, we deployed geolocation loggers on black-legged kittiwakes Rissa tridactyla at 10 colonies in the north-east Atlantic and examined relationships between the timing and destination of migratory movements and breeding success in the year of deployment and subsequent season. Both successful and unsuccessful breeders wintered primarily in the north-west Atlantic. Breeding success affected the timing of migration, whereby unsuccessful breeders departed the colony earlier, arrived at the post-breeding and main wintering areas sooner, and departed later the following spring. However, these patterns were only apparent in colonies in the south-west of the study region. Furthermore, the effect of breeding success was stronger on migration timing in the first part of the winter than later. Timing of migratory movements was weakly linked to subsequent breeding success, and there was no detectable association between breeding success in the 2 seasons. Our results indicate temporal structure and spatial heterogeneity in the strength of seasonal interactions among kittiwakes breeding in the north-east Atlantic. Variable fitness consequences for individuals from different colonies could have important implications for population processes across the species' range and suggest that the spatiotemporal dynamics of carry-over effects warrant further study.

“…Male breeders seemed to be the most sensitive to POPs. Energetic and time-dependent costs of reproduction have been shown to induce downstream consequences on reproductive investment during the following breeding season (carry over effect, Catry et al, 2013). One may suggest that POPs burden may intensify these carry over effects, but studies are needed to either rebut or confirm this hypothesis.…”

27Chronic exposure to pollutants may represent a threat for wildlife. We tested whether adult 28 survival rate, breeding probability and breeding success the year of sampling and the 29 following year were affected by blood levels of mercury or persistent organic pollutants in 30Svalbard black-legged kittiwake Rissa tridactyla, by using capture-mark-recapture models 31 over a five-year period. Survival rate was negatively linked to HCB levels in females, to 32 chlordane mixture and oxychlordane, tended to decrease with increasing PCBs or DDE levels, 33 but was unrelated to mercury. Breeding probability decreased with increasing mercury levels 34 during the sampling year and with increasing CHL or HCB levels during the following year, 35 especially in males observed as breeders. Surprisingly, the probability of raising two chicks 36 increased with increasing HCB levels. Although levels of these legacy pollutants are expected 37 to decline, they represent a potential threat for adult survival rate and breeding probability,

“…Bulwer's petrels are amongst the smallest members of the Procellariidae family (length: 26 cm; approximately weight: 100 g). They are shallow divers (Mougin and Mougin 2000) whose diet is mostly based on mesopelagic fishes (Zonfrillo 1986;Neves et al 2011;Carvalho 2012). Therefore, and for the reasons stated above, we could expect this species to present a migratory strategy and an atsea distribution and behaviour considerably different from other much better studied Procellariidae.…”

Small-sized nocturnal Procellariiformes are abundant predators in oceanic areas worldwide and are thought to play an important role in many marine food webs as consumers of superabundant mesopelagic prey. However, the spatial ecology and foraging behaviour of the great majority of these species remain largely unknown. We studied the non-breeding distribution and at-sea activity of a migratory small-sized Procellariiform, the Bulwer's petrels Bulweria bulwerii, from the Selvagem Island colony (subtropical Northeast Atlantic). We found that soon after breeding Bulwer's petrels migrate towards deep (mean depth of 4416 m), open oceanic waters of the tropical Atlantic, spending the winter far from shelf and shelf-break areas, on regions avoided by most other avian migrants in the Atlantic. When at sea, Bulwer's petrels spent more time flying during the night ([90 %, all year round) than any other seabird studied so far. This nighttime activity was not influenced by the lunar cycle, suggesting that this highly specialised nocturnal seabird is probably very well adapted to locating and capturing prey even in very dark conditions. The results from the present study may have important implications for the identification of important bird areas in the marine realm, whose boundaries have been delineated so far mostly on the basis of the distribution and behaviour of better studied medium-to large-sized seabirds.Keywords At-sea activity Á Bulwer's petrels Á Migration Á Procellariiformes Á Seabirds Zusammenfassung Wanderer ü ber der Tiefsee: Zugverhalten und Verbreitung des hochgradig pelagischen Bulwersturmvogels
