“…There are correlative studies suggesting that this effect may occur in nature although it is unclear whether plastic ingestion causes low weight or is a result of low availability of food (10,15). Reduced body condition (i.e., lower fledging weight) has been linked to reduced survival of juvenile seabirds (23)(24)(25). In addition to physical effects, high plastic loads are correlated with increased organic pollutant loads in field observations of seabirds (26), with supportive experimental results demonstrating a connection between pollution, concentration of pollutants by plastics, and release into seabird tissues during digestion (13,16,27).…”

Plastic pollution in the ocean is a global concern; concentrations reach 580,000 pieces per km 2 and production is increasing exponentially. Although a large number of empirical studies provide emerging evidence of impacts to wildlife, there has been little systematic assessment of risk. We performed a spatial risk analysis using predicted debris distributions and ranges for 186 seabird species to model debris exposure. We adjusted the model using published data on plastic ingestion by seabirds. Eighty of 135 (59%) species with studies reported in the literature between 1962 and 2012 had ingested plastic, and, within those studies, on average 29% of individuals had plastic in their gut. Standardizing the data for time and species, we estimate the ingestion rate would reach 90% of individuals if these studies were conducted today. Using these results from the literature, we tuned our risk model and were able to capture 71% of the variation in plastic ingestion based on a model including exposure, time, study method, and body size. We used this tuned model to predict risk across seabird species at the global scale. The highest area of expected impact occurs at the Southern Ocean boundary in the Tasman Sea between Australia and New Zealand, which contrasts with previous work identifying this area as having low anthropogenic pressures and concentrations of marine debris. We predict that plastics ingestion is increasing in seabirds, that it will reach 99% of all species by 2050, and that effective waste management can reduce this threat.extinction | ingestion | marine debris | risk analysis | seabird

International audienceLindström (in Trends Ecol Evol 14:343-347, 1999) synthesized knowledge about "early development and fitness in birds and mammals", interesting tracks and challenges for future studies. Today, there is unambiguous evidence that Lindström's first statement holds in long-lived birds: "It is obvious that adverse environmental conditions might have immediate effects [...]." However, whether there are "long-term fitness consequences of conditions experienced during early development" (Lindström's second statement) is unclear for long-lived birds. The extent to which the disadvantage of frail individuals at independence is expressed predominantly in terms of higher mortality and disappearance from the population before recruitment, or persists after recruitment, is still an open question. Due to the rarity of relevant data and the fact that most studies are retrospective, heterogeneity in methods and timescales hampers the identification of general patterns. Nevertheless, several studies have provided evidence of a relationship between early conditions and future reproductive parameters, or lifetime reproductive success. Evidence from large mammals suggests substantial long-term individual and population effects of early conditions, including trans-generational maternal effects. Evidence from short-lived birds also suggests long-term individual consequences, and maternal effects have been documented in long-lived ones. Despite logistical and financial difficulties inherent in long-term studies, they are the only way of addressing Lindström's second statement. Existing long-term longitudinal datasets should be re-analyzed using recently developed capture-mark-recapture models handling state uncertainty and unobservable heterogeneity in populations. Statistical methods designed to estimate lifetime reproductive success or incorporate pedigree information in standard situations of studies of wild vertebrates with imperfect detection offer new opportunities to assess long-term fitness consequences of early development in long-lived birds

“…Chicks with a high body mass at fledging have enhanced post-fledging survival and recruitment into the breeding population due to larger energy reserves that provide a buffer against energetic and environmental stresses (N aef-Daenzer et al 2001, Morrison et al 2009, Chapman et al 2010, Saraux et al 2011. Seabirds are affected by many environmental, weather, and climatic factors acting on different scales (Smith et al 1999, Wilson et al 2001, Ainley et al 2005.…”

The fledging mass of penguin chicks can be an indicator of food availability and environmental conditions at a penguin colony. For the period 1989 to 2011, we analyzed predictor variables of environmental and food resource factors acting on multiple spatial scales near Palmer Station, Antarctica, that may influence the interannual variability in Adélie penguin chick fledging mass (CFM). To understand the influence of parental Adélie penguin diet on CFM, we modeled the energy density and krill demographics of penguin diet samples. We found a weak but significant positive relationship between the proportion of immature krill in adult penguin diets and CFM, which may indicate that krill recruitment and prey availability to adults influences CFM. However, the impact of large-scale climate and local weather outweighed the impact of parental diet characteristics on CFM. CFM was negatively associated with a positive Antarctic Oscillation (or Southern Annular Mode) and increased westerly winds and was positively associated with increased air temperature. The mechanistic relationship between climate, local weather, and CFM could include direct and indirect impacts, such as increased thermo-regulative costs for unattended chicks, decreased chick feeding frequency, and smaller meal mass for chicks driven by the geophysical transport of krill by climate and wind events.
