Abstract |
Summary 1.Modulating the adrenocortical response to stress and the corresponding mobilization of energy substrates allows animals to cope with energy-demanding challenges imposed by ecological constraints. Whether such a modulation occurs during the fledging process of the king penguin chick (Aptenodytes patagonicus) was examined. In this seabird species, fledging is associated with moult completion, prolonged fasting and transition from terrestrial to marine life. 2.Specifically, it was tested whether the adrenocortical and metabolic responses to a capture-handling stress i. depended on the developmental/moulting status of pre-fledging birds, ii. were affected by their nutritional status, and iii. were inter-related. 3.The adrenocortical response was 23 times lower at moult end and fledging than at the onset of moult, 1Â month earlier. No direct evidence for a link between the adrenocortical response and moult-related changes in circulating thyroid hormones was obtained. 4.At the onset of moult, chicks were in a nutritional status corresponding to phase I of fasting whereas those at moult end and fledging were in phase II of fasting. Thus, the adrenocortical response depended on nutritional status, being blunted during phase II when body proteins were spared and fat stores preferentially mobilized. 5.The metabolic response to acute stress was characterized by an increase in plasma glucose, NEFA and uric acid and by a decrease in plasma -hydroxybutyrate. Differences in this response between phase I and phase II fasting chicks suggest that the mix of energy substrates used to fuel energy demand during acute stress is the same as that routinely fuelling daily energy expenditure. We obtained no evidence for an interaction between corticosterone and metabolic responses. 6.Overall, the results suggest that, in pre-fledging king penguin chicks, the nutritional rather than the developmental/moulting status modulates the adrenocortical and metabolic responses to an acute stress. The possible adaptive function of the blunting of these responses by the time of fledging is discussed.

Abstract |
The chemical composition of marine aerosols as a function of their size is an important parameter for the evaluation of their impact on the global climate system. In this work we model fine particle organic matter emitted by sea spray processes and its influence on the aerosol chemical properties at the global scale using the off-line global Chemistry-Transport Model TM5. TM5 is coupled to a microphysical aerosol dynamics model providing size resolved information on particle masses and numbers. The mass of the emitted sea spray particles is partitioned between water insoluble organic matter (WIOM) and sea salt components in the accumulation mode using a function that relates the emitted organic fraction to the surface ocean chlorophyll-a concentrations. The global emission in the submicron size range of organic matter by sea spray process is 8.2 Tg yr-1, compared to 24 Tg yr-1 sea-salt emissions. When the marine sources are included, the concentrations of modeled primary particulate organic matter (POM) increase mainly over the oceans. The model predictions of WIOM and sea salt are evaluated against measurements carried out at Mace Head (Northern Hemisphere) and Amsterdam Island (Southern Hemisphere), showing that in clean marine conditions WIOM marine emissions contribute significantly to POM values. An estimation of the sea spray organic source in the coarse mode is carried out on the basis of field observations as well as laboratory experiments: the mass of sea spray organic matter in the coarse size range is ca 52% of the total primary organic fraction, leading to a total marine POM emission of 17.2 Tg yr-1. |
