Abstract:

D'abord considérées comme d'immenses barrières empêchant la navigation vers le pôle Sud, les plateformes de glace permirent tout compte fait aux explorateurs de pénétrer au coeur de la calotte Antarctique à l'aube du XXe siècle. Leur cartographie fut progressivement obtenue à l'explosif, jusqu'à ce que les ondes sismiques fissent place aux ondes radar, aéroportées puis satellitaires. Sur la base d'observations et des premiers modèles numériques de climat, la désintégration de plateformes de glace sur la péninsule Antarctique fut annoncée une quinzaine d'années avant d'être observée pour la pre

Abstract:

Southern elephant seal (Mirounga leonina) populations appear remarkably unaffected by interactions with humans. They are very tolerant of close human presence whilst they are ashore for pupping, mating and moulting. Their behaviour in close proximity to helicopter operations suggests disturbance of moulting male M. leonina is minimal. There is no evidence that M. leonina have been affected by persistent organic pollutants; and few M. leonina have been reported as having been injured or killed by interactions with fishery gear. The number of prey species common to their diet and commercial fish

Sin embargo, la información sobre su distribución en la Plataforma Continental Argentina es escasa y se limita a unas pocas observaciones obtenidas principalmente en los golfos norpatagónicos y en las Islas Malvinas.

Abstract:

The taxonomy of the southeastern Brazilian species of Psolus is reviewed and two new species described. Additionally, P. vitoriae is redescribed based on a newly designated neotype and supplemental material from the type locality and nearby regions. The synonymy of P. marcusi with P. patagonicus is called into question. The calcareous ring is useful for distinguishing between some Psolus species. Psolus tommasi sp. nov. is characterized by having five oral valves, an anus covered by a variable number of small, irregular anal valves, oral and anal valves distinct from body wall scales, calcareo

Abstract:

In a 5-yr (1979-84) study of 6 species of fruit pigeon in lowland (dry) and upland (wet) subtropical rain forests in the Jimna and Conondale Ranges, the effects of forest phenology on pigeon abundance were investigated. The pigeons utilized 89 species of plants from 39 families of trees, palms and vines. The seasonal availability of fruit was similar in each forest type: most plant species bore crops during the wet season (Dec.-Mar.) and held crops into the early dry season (April-May); the late dry season (June-Oct.) was a time of general fruit shortage. More than 60% of the species of food p

Abstract:

AbstractConnectivity is a fundamental process of population dynamics in marine ecosystems. In the last decade, with the emergence of new methods, combining different approaches to understand the patterns of connectivity among populations and their regulation has become increasingly feasible. The Western Antarctic Peninsula (WAP) is characterized by complex oceanographic dynamics, where local conditions could act as barriers to population connectivity. Here, the notothenioid fish Harpagifer antarcticus, a demersal species with a complex life cycle (adults with poor swim capabilities and pelagic

Abstract:

Surface melt over the Antarctic ice shelves is one of the largest uncertainties related to sea level rise over the 21st century. However, current climate models still struggle to accurately represent it, limiting our comprehension of processes driving melt spatial and temporal variability and its consequences on the stability of the Antarctic ice sheet. Recent advances in Earth monitoring thanks to satellites have enabled new estimations of Antarctic melt extent. They can detect if and where melt occurs, while the amount of meltwater produced can only be deduced from model simulations. In orde

Abstract:

This discussion paper interprets the findings of a recent study comparing melt estimates from the regional atmospheric model MAR, those derived from Automatic Weather Stations (AWS), and microwave remote sensing images over the Antarctic Peninsula from 2019 to 2021. Our interpretation reveals a paradox: MAR overestimates melt when compared to AWS-based melt estimates, yet underestimates melt when compared to satellite imagery. This discrepancy underscores a fundamental gap in our understanding of surface processes. To illustrate the potential implications of this gap, we present a fictional (“

Abstract:

Antarctica is the largest potential contributor to sea-level rise and needs to be monitored. It is also one of the first victims of global warming. However, it is often difficult to obtain high-resolution data on this vast and distant continent. Thanks to the Copernicus space program providing free and open access to high-quality data, this paper aims to show the complementarity between Sentinel-1 images and Modèle Atmosphérique régional (MAR) data over Antarctica. This study is conducted over Roi Baudouin Ice Shelf. The complementarity between the two datasets is established by a quantitative

Abstract:

Diazotrophic communities contribute inorganic nitrogen for the primary productivity of the marine environment by biological nitrogen fixation (BNF). They play a vital role in the biogeochemical cycle of nitrogen in the marine ecological environment. However, there is still an incomplete understanding of BNF and diazotrophs in artificial seaweed farms. Therefore, this study comprehensively investigated the temporal variations of BNF associated with Gracilariopsis lemaneiformis, as well as the diazotrophic communities associated with macroalgae and its surrounding seawater.
