  Title Composition of chick meals from one of the main little auk (Alle alle) breeding colonies in Northwest Greenland Type Journal Article
  Year 2014 Publication Polar Biology Abbreviated Journal  
  Volume 37 Issue 7 Pages 1055-1060-  
  Keywords Little auk, Chick diet, High arctic, Seabirds, Calanus species,  
  Abstract During the last decade, increasing information on little auk (Alle alle) biology, ecology and behaviour has been reported. However, only a few of these studies have focused on the breeding population in the Avanersuaq (Thule) district of Northwest Greenland, where 80 % of the global little auk population is estimated to breed. This study reports on the chick diet composition from one of the largest colonies, the Paakitsoq colony, located on the south-eastern margin of the North Water (NOW) Polynya. Results revealed the highest proportion of Calanus hyperboreus, a large lipid-rich copepod, in chick diet reported for any little auk colony. Results confirmed that the cold,
highly productive waters of the NOW Polynya are favourable foraging grounds for the little auks during the breeding season. Species diversity within and between the chick meals was low, which probably reflects a high availability of a few preferred prey species. Individual chick meals were generally low in number of prey items and total energy content compared with other published results. This may be explained by a higher feeding frequency or by the samples being collected late in the breeding period (during late chick rearing), when chicks have a reduced growth rate and may require less energy than at earlier developmental stages.

  Title Stress hormones in relation to breeding status and territory location in colonial king penguin: a role for social density? Type Journal Article
  Year 2014 Publication Oecologia Abbreviated Journal  
  Volume 175 Issue 3 Pages 763-772-  
  Keywords Coloniality, Corticosterone, Crowding, Population density, Glucocorticoids, Oxidative stress, Seabird, Stress, Territory location,  
  Abstract Because glucocorticoid (stress) hormones fundamentally affect various aspects of the behaviour, life history and fitness of free-living vertebrates, there is a need to understand the environmental factors shaping their variation in natural populations. Here, we examined whether spatial heterogeneity in breeding territory quality affected the stress of colonial king penguin (Aptenodytes patagonicus). We assessed the effects of local climate (wind, sun and ambient temperature) and social conditions (number of neighbours, distance to neighbours) on the baseline levels of plasma total corticosterone (CORT) in 77 incubating and 42 chick-brooding birds, breeding on territories of central or peripheral colony location. We also assessed the oxidative stress status of a sub-sample of central vs. peripheral chick-brooders to determine whether chronic stress arose from breeding on specific territories. On average, we found that brooders had 55 % higher CORT levels than incubators. Regardless of breeding status, central birds experienced greater social density (higher number of neighbours, shorter distance between territories) and had higher CORT levels than peripheral birds. Increasing social density positively explained 40 % of the variation in CORT levels of both incubators and brooders, but the effect was more pronounced in brooders. In contrast, climate was similar among breeding territories and did not significantly affect the CORT levels of breeding birds. In brooders, oxidative stress status was not affected by local density or weather conditions. These results highlight that local heterogeneity in breeding (including social) conditions may strongly affect the stress levels of breeding seabirds. The fitness consequences of such variation remain to be investigated.

  Title Serological evidence for the presence of non-pathogenic rabbit haemorrhagic disease virus-like strains in rabbits (Oryctolagus cuniculus) of the Kerguelen archipelago Type Journal Article
  Year 2010 Publication Polar Biology Abbreviated Journal Polar Biol.  
  Volume 33 Issue 7 Pages 985-989 -989  
  Keywords Biomedical and Life Sciences,  
  Abstract Antibodies raised against a Lagovirus were found in healthy rabbits Oryctolagus cuniculus sampled in 2003 and 2004 in the Kerguelen archipelago. The serological test we used enabled the detection of antibodies due to both pathogenic and non-pathogenic viruses related to the rabbit haemorrhagic disease virus (RHDV). The overall proportion of seropositive rabbits was 35% and differed between sites. Since previous studies have failed to detect antibodies raised against pathogenic RHDV strains, the antibodies detected in the present study were likely due to non-pathogenic strains. The interest of these strains circulating in the Kerguelen archipelago is that they have evolved independently of those detected in the other parts of the world and should derive from an ancestral RHDV precursor. Their characterization may help understanding the evolution of the virus and the emergence of the disease.

  Title Breeding ecology of the gentoo penguin Pygoscelis papua at Kerguelen Archipelago Type Journal Article
  Year 2009 Publication Polar Biology Abbreviated Journal Polar Biol.  
  Volume 32 Issue 10 Pages 1495 -1505  
  Keywords Biomedical and Life Sciences,  
  Abstract The gentoo penguin (Pygoscelis papua) is one of the most widespread penguin species and has been proven to be highly plastic in many aspects of its ecology. However, data from their sub-Antarctic range suggest an unexplained decline of their populations over the last 1020 years, stressing the need for additional knowledge on their breeding ecology and demography. The present study provides insights into the breeding ecology of the gentoo penguin at a major breeding site, Kerguelen Archipelago, over three breeding seasons (1987, 2002 and 2003). Similarly to other northern populations, gentoo penguins breeding at Kerguelen exhibited winter laying, slow provisioning rate, slow growth rate associated with an extended rearing period and relatively low breeding success compared to southern populations. Our study also revealed interannual differences in the timing of laying and growth parameters as well as unusual sex differences in parental investment. Despite their high plasticity, there are indications that gentoo penguins at the northern edge of their range might work at the upper limit of their capacities. Sub-Antarctic populations would, therefore, be more sensitive to environmental changes than more southerly ones and need to be closely monitored.
