| Abstract |
Nous avons utilisé les données de végétation récoltées entre janvier 1985 et janvier 1988 sur une base mensuelle par Boussès (1991, site de Molloy, Grande Terre). A l'aide d'un modèle non linéaire généralisé (incluant une distribution négative binomiale), nous avons montré qu'il y avait une relation très forte (corrélation entre prédictions du modèle et observations de 0.89 [0.77;0.95]95%) entre la composante saisonnière du NDVI et la biomasse mesurée sur le terrain (biomasse de Acaena magellanica de Taraxacum officinnale, qui sont les deux espèces dominantes du peuplement étudié). Nous avons également montré que pour les fortes valeurs de biomasse mesurée sur le terrain, le NDVI sature, et la relation atteint la valeur asymptotique de 0.54 (± 0.05). Ces résultats suggèrent que, dans ces conditions, le NDVI est un bon indicateur de la production de biomasse végétale |

| Abstract |
The study of scats of adult male Antarctic fur seals Arctocephalus gazella (AFS) revealed occasional frequent capture of penguins. Although AFS adult males have been occasionally reported to kill king penguins Aptenodytes patagonicus at the shore, here we report the first observations of at-sea predation by AFS on adult king penguins in the Crozet archipelago, southern Indian Ocean. During our 20 days survey, we observed 17 penguins attacked and either severely injured or killed and consumed. Only AFS adult males were seen catching king penguins successfully. Some adult females and sub-adults also attempted to catch penguins, either at sea or in land, and so did subantarctic fur seals Arctocephalus tropicalis individuals. Our results confirm the ability of fur seals to catch and predate large seabirds, even at sea. |

| Abstract |
The effects of temporal, spatial, environmental and operational effects on seabird incidental mortality in the legal Patagonian toothfish longline fishery operating, between 2003 and 2006, in French exclusive economic zones of Crozet and Kerguelen Islands were analysed. During the study period, the mean bycatch rate varied from 0.05 to 0.12 birds per 1,000 hooks. Two species were concerned by incidental mortality: white-chinned petrels (88%) and grey petrels (11.5%). Males of white-chinned petrel seemed more at a risk than females. Logbooks data tended to underreport mortality when compared with dedicated fishery observers. The results indicate that temporal (season or phenology) and spatial (area) factors reflecting mortality risk for seabirds played the most significant role in the incidental mortality of the two species. Operational (integrated weight mainline, number of scaring lines and number of hooks hauled) and environmental factors (wind/vessel angle, moon brightness) were also influential, although less significantly, in increasing this mortality risk. Our two steps analyses by separately modelling the probability of presence and the abundance given presence suggest that the decrease in seabird bycatch over the period was mainly due to an important decrease in probability (occurrence) of mortality. |

| 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. |

| Abstract |
A new genus and species of deep-sea eelpout (Zoarcidae), Barbapellis pterygalces , is herein described from a single adult female specimen carrying eggs and measuring 204 mm in total length. It was collected on the eastern Antarctic continental slope, off Terre Adélie, at ca . 1,200 m depth, on muddy bottom. Barbapellis is placed in the subfamily Gymnelinae and can be distinguished from all other genera by morphological characters unusual in zoarcids as well as by molecular barcoding. The genus is characterized by the presence of a complex system of cephalic skin crests and flaps, especially well developed around the mouth. A new terminology is proposed for the eleven crests and sevenfolds described. The skin folds may be used for foraging on muddy sea bottoms. The genus is also characterized by large, flexible, and highly palmate pectoral fins. The designation of the new genus is discussed. |

| Abstract |
The use of data-loggers has permitted to explore the biology of free-ranging animals. However, this method has also been reported to reduce reproductive success while the reasons of this deleterious effect remain poorly documented. In this study, we aimed to identify critical periods of the breeding cycle of Ad,lie penguins (Pygoscelis adeliae) when the reproductive success may decrease because of instrumentation. For this purpose, we monitored 40 pairs, where one parent was instrumented before egg laying and 30 pairs without devices (controls). These pairs were followed at least during the incubation period but the majority was monitored during the entire breeding season. Reproductive success was affected in pairs where males were instrumented. This was not due to extra chick mortality during chick rearing but to a significantly lower hatching success. Moreover, the use of artificial eggs recording incubation temperatures and egg rotation indicated that in instrumented incubating males, eggs spent as much time at optimal incubation temperatures as control eggs but were rotated at a higher frequency. In Ad,lie penguins, males initiate incubation and it has been established that the early stage of incubation is one of the most critical periods for embryonic development. The low hatching rate observed in instrumented males was associated with a higher egg rotation rate, perhaps as a stress response to the presence of the instrument. Even though the causal effects remain unclear, instrumentation severely affected hatching success. For these reasons, we recommend equipping birds after the early incubation.
