Title What can we learn from HF signal scattered from a discrete arc? Type Journal Article
Year 2009 Publication Ann. Geophys. Abbreviated Journal
Volume 27 Issue 5 Pages 1887 -1896
Keywords
Abstract We present observations of a discrete southward propagating arc which appeared in the mid-night sector at latitudes equatorward of main substorm activity. The arc observations were made simultaneously by the ALFA (Auroral Light Fine Analysis) optical camera, the SuperDARN-CUTLASS HF radar and the Demeter satellite during a coordinated multi-instrumental campaign conducted at the KEOPS/ESRANGE site in December 2006. The SuperDARN HF signal which is often lost in the regions of strong electron precipitation yields in our case clear backscatter from an isolated arc of weak intensity. Consequently we are able to study arc dynamics, the formation of meso-scale irregularities of the electron density along the arc, compare the arc motion with the convection of surrounding plasma and discuss the contribution of ionospheric ions in the arc erosion and its propagation.

Title Transcriptional analysis of skeletal muscle adaptations to marine life in king penguin juveniles (Aptenodytes patagonicus). Type Journal Article
Year 2009 Publication FASEB JOURNAL Abbreviated Journal
Volume FASEB J Issue 23 Pages 629.5
Keywords
Abstract King penguin chicks, that are strictly terrestrial during first year after hatching, must depart to sea to reach nutritional emancipation. Juvenile survival therefore depends on their adaptation to the energetic challenges of marine life: 1) harsh thermal environment, 2) long distant food resources, 3) repeated, deep and prolonged nutritional divings.

To elucidate these adaptations, the transcriptome of pectoralis muscle, the main thermogenic and locomotor tissue, was analysed in juveniles that had never been to sea (n=4) and in naturally adapted juveniles (n=3) by using chicken Affymetrix DNA chips (Profilexpert, Lyon).

Results showed the differential expression of nearly 3600 genes after marine life. Genes encoding enzymes of carbohydrate metabolism were down regulated while those encoding lipid transport and catabolism were up regulated suggesting an increased use of lipids as energy substrates. Further, transcripts encoding enzymes involved in cellular defense against reactive oxygen species and the associated injuries were also up regulated, suggesting an adaptive response against oxidative stress.

This study opens large perspectives to elucidate how king penguins can survive in an energetically unfavorable and pro-oxidative environment and what contributes to their remarkable longevity.

This study received the financial support of the French Polar Institut (IPEV).

Title Are stress hormone levels a good proxy of foraging success? An experiment with king penguins, Aptenodytes patagonicus. Type Journal Article
Year 2009 Publication The Journal of experimental biology Abbreviated Journal J. Exp. Biol.
Volume 212 Issue 17 Pages 2824 -9
Keywords Animals, Body Composition, Corticosterone, Corticosterone: blood, Eating, Feeding Behavior, Female, Male, Spheniscidae, Spheniscidae: anatomy & histology, Spheniscidae: metabolism, Spheniscidae: physiology,
Abstract In seabirds, variations in stress hormone (corticosterone; henceforth CORT) levels have been shown to reflect changing marine conditions and, especially, changes in food availability. However, it remains unclear how CORT levels can be mechanistically affected by these changes at the individual level. Specifically, the influence of food acquisition and foraging success on CORT secretion is poorly understood. In this study, we tested whether food acquisition can reduce baseline CORT levels (;the food intake hypothesis') by experimentally reducing foraging success of King Penguins (Aptenodytes patagonicus). Although CORT levels overall decreased during a foraging trip, CORT levels did not differ between experimental birds and controls. These results demonstrate that mass gain at sea is not involved in changes in baseline CORT levels in this species. The overall decrease in CORT levels during a foraging trip could result from CORT-mediated energy regulation (;the energy utilisation hypothesis'). Along with other evidence, we suggest that the influence of foraging success and food intake on CORT levels is complex and that the ecological meaning of baseline CORT levels can definitely vary between species and ecological contexts. Therefore, further studies are needed to better understand (1) how baseline CORT levels are functionally regulated according to energetic status and energetic demands and (2) to what extent CORT can be used to aid in the conservation of seabird populations.

Title Metabolic rate throughout the annual cycle reveals the demands of an Arctic existence in Great Cormorants Type Journal Article
Year 2011 Publication Ecology Abbreviated Journal Ecology
Volume 92 Issue 2 Pages 475 -486
Keywords arctic, basal metabolic rate, catch per unit effort, cpue, daily energy expenditure, day length, diving depths, field metabolic rate, foraging efficiency, great cormorant, greenland, phalacrocorax carbo, seasonal variation,
Abstract Aquatic endotherms living in polar regions are faced with a multitude of challenges, including low air and water temperatures and low illumination, especially in winter. Like other endotherms from cold environments, Great Cormorants (Phalacrocorax carbo) living in Arctic waters were hypothesized to respond to these challenges through a combination of high daily rate of energy expenditure (DEE) and high food requirements, which are met by a high rate of catch per unit effort (CPUE). CPUE has previously been shown in Great Cormorants to be the highest of any diving bird. In the present study, we tested this hypothesis by making the first measurements of DEE and foraging activity of Arctic-dwelling Great Cormorants throughout the annual cycle. We demonstrate that, in fact, Great Cormorants have surprisingly low rates of DEE. This low DEE is attributed primarily to very low levels of foraging activity, particularly during winter, when the cormorants spent only 2% of their day submerged. Such a low level of fo...

Title The relationship between sea surface temperature and population change of Great Cormorants Phalacrocorax carbo breeding near Disko Bay, Greenland Type Journal Article
Year 2011 Publication Ibis Abbreviated Journal Ibis (Lond. 1859)
Volume 153 Issue 1 Pages 170 -174
Keywords Arctic warming, climate change, diving, Phalacrocorax, thermoregulation, vision,
Abstract Arctic seas have warmed and sea ice has retreated. This has resulted in range contraction and population declines in some species, but it could potentially be a boon for others. Great Cormorants Phalacrocorax carbo have a partially wettable plumage and seem poorly suited to foraging in Arctic waters. We show that rates of population change of Cormorant colonies around Disko Bay, Greenland, are positively correlated with sea surface temperature, suggesting that they may benefit from a warming Arctic. However, although Cormorant populations may increase in response to Arctic warming, the extent of expansion of their winter range may ultimately be limited by other factors, such as sensory constraints on foraging behaviour during long Arctic nights.
