Abstract |
A preliminary study has demonstrated that the structure and species composition of microbial communities associated with events of dust deposition from the Sahara Desert to the Mont Blanc glacier varied considerably between samples originating from different time periods. Even for depositions within a single month, the dominant microbial phylotypes and candidates to colonize the snow pack were different. It is therefore highly probable that the structure and species composition of microbial communities will be different between any events of the kind. Apparently, the phenomenon does not correlate with the time the dust stays in the snow cover and consequently with the probable development of microorganisms in situ (three months, one month, and one week). The reasons for the variation may be the differences in conditions in the epicenter of a specific North African dust storm, as well as the history of the dust transport in the atmosphere. The candidates for joining the snow biome of Mont Blanc turned out to be different for three dust events (DEs) and belong to different, mostly minor, phylotypes related to Crossiella cryophilus ( Actinobacteria ), Devosia limi (- Proteobacteria ), Deinococcus claudionis Deinococcus-Thermus ), Anabaena sp. ( Cyanobacteria ), and Hymenobacter soli ( Bacteroidetes ). Since all these phylotypes have been previously isolated from soil samples of the Antarctic and Arctic, Arctic snow and ice, and the Alpine belt soils and sedimentary rocks of the glacier bed, they were tentatively ascribed to the group of snow pack colonizers. |

Abstract |
BACKGROUND:Recent developments in high-throughput methods of analyzing transcriptomic profiles are promising for many areas of biology, including ecophysiology. However, although commercial microarrays are available for most common laboratory models, transcriptome analysis in non-traditional model species still remains a challenge. Indeed, the signal resulting from heterologous hybridization is low and difficult to interpret because of the weak complementarity between probe and target sequences, especially when no microarray dedicated to a genetically close species is available.RESULTS:We show here that transcriptome analysis in a species genetically distant from laboratory models is made possible by using MAXRS, a new method of analyzing heterologous hybridization on microarrays. This method takes advantage of the design of several commercial microarrays, with different probes targeting the same transcript. To illustrate and test this method, we analyzed the transcriptome of king penguin pectoralis muscle hybridized to Affymetrix chicken microarrays, two organisms separated by an evolutionary distance of approximately 100 million years. The differential gene expression observed between different physiological situations computed by MAXRS was confirmed by real-time PCR on 10 genes out of 11 tested.CONCLUSIONS:MAXRS appears to be an appropriate method for gene expression analysis under heterologous hybridization conditions. |

Abstract |
In vertebrates, stressors such as starvation or predator attacks stimulate the rapid elevation of circulating glucocorticoid hormones, triggering physiological and behavioral responses that aid immediate survival but simultaneously inhibit reproduction. This stress response has been proposed to serve as a physiological mediator of life-history trade-offs: when the value of current reproduction is high relative to the value of future reproduction and survival, a mitigated stress response is expected to enable successful breeding and maximize fitness. Using phylogenetic comparative analyses, we investigated baseline and peak stress-induced plasma corticosterone levels during parental care in 64 bird species. We found that (1) species with a higher value of the current brood relative to future breeding mounted weaker corticosterone responses during acute stress, and (2) females in species with more female-biased parental care had weaker corticosterone responses. These results support the brood value hypothesis, suggesting that the stress response evolves as an adaptive basis for life-history strategies. Further, we found that (3) baseline corticosterone correlated positively with brood value and negatively with body mass, and (4) peak corticosterone was greater in species breeding at higher latitudes. The latter findings suggest that circulating corticosterone concentrations might be matched to the anticipated demands and risks during nesting.

Abstract |
In situ observations show that snow accumulation is 10% larger 25 km north than south of the summit of Dome C on the east antarctic plateau. The mean wind direction is southerly. Although a slight slope-related diverging katabatic flow component is detectable, the area is an essentially flat (10 m elevation change or less) homogeneous snow surface. The European Center for Medium-range Weather Forecasts meteorological analyses data reproduce a significant accumulation gradient and suggest that 90% of the the mean accumulation results from the 25% largest precipitation events. During these events, air masses originate from coastal areas in the north rather than from inland in the south. Radiative cooling condensation occurs on the way across the dome and as the moisture reservoir is depleted less snow is dumped 25 km south than north, with little direct impact from the local (50-km scale) topography. Air masses are warmer on average, and warmer north than south, when originating from the coast. This marginally affects the mean temperature gradients. The moisture gradients are more affected because moisture is nonlinearly related to temperature: the mean atmospheric moisture is larger north than south. Significant meteorological and hydrological gradients over such relatively small distances (50 km) over locally flat region may be an issue when interpreting ice cores: although cores are drilled at the top of domes and ridges where the slopes and elevation gradients are minimal, they sample small surfaces in areas affected by significant meteorological and hydrological spatial gradients. |
