“…During the last few decades, the Antarctic ecosystem has been changing, mainly due to climatic fluctuations and the direct impacts of human activity [20,21]. These changes are visible not only in fluctuations of abiotic factors [22,23], but also at the functional level of the pelagic communities [24][25][26][27][28]. The responses of zooplankton to the warming Antarctic marine environment are very difficult to characterize due to the complex interactions between predators and prey [29,30].…”

Appendicularians are one of the most common animals found within zooplankton assemblages. They play a very important role as filter feeders but are, unfortunately, inconsistently reported in the Antarctic literature. The present paper attempts to describe the zonal diversity of appendicularians and the main environmental factors influencing their communities in the Drake Passage. Samples were collected during Antarctic summer in 2009–2010. A total of eight species of larvaceans were identified. Fritillaria borealis was the species found in the highest numbers in almost the entire studied area, and was observed at all sampling stations. The distributions of other taxa were limited to specific hydrological zones and hydrological conditions. F. fraudax and Oikopleura gaussica were typical of the areas between the Polar Front and the Subantarctic Front zones, and their distributions were significantly correlated with temperature and salinity, likely making them good indicator species. The F. fusiformis distribution was strictly related to South American waters. In summary, temperature was the strongest environmental factor influencing the larvacean community structure in the Drake Passage, and we also found that testing environmental factors on larvaceans as a whole group did not give entirely reliable results.

“…More recently, a study on the identification and quantification of Polychlorinated dibenzo-p-dioxins, dibenzofurans (PCDD/Fs) and their precursorspentachlorophenol (PCP) and triclosan (TCS) contained in sediments in the Arctic and Antarctic, has revealed that 60% of these compounds were identified in the bottom sediments collected. Furthermore, 50% of the samples exceeded environmental limits, even reaching concentration levels comparable to those observed in mid-latitude regions [125]. These remarks thus could constitute an extreme risk for the conservation, prevention and sustainability of polar ecosystems.…”

The polar regions had long been regarded as healthy ecosystems free of any hazardous traces left by human activity. Unfortunately, since the intensification of industrial activities leading to huge releases into environment, anthropogenic pollutants through global atmospheric and ocean currents were found with more or less high concentrations in all polar ecosystem compartments. Among these pollutants, one of the most dangerous categories is persistent organic pollutants (POPs). Since polar ecosystems are fragile and have a limited capacity for resilience, their contamination can generate unforeseeable consequences that can affect global cycles. Our work aims to compile data collected through a review of studies carried out within the framework of POPs evolution in polar regions, and then to compare them in order to identify future improvements to be made within the framework of POPs monitoring in the Arctic and Antarctic. According to our observations, POPs concentrations in all ecosystem compartments in Arctic are much higher than in Antarctica. Moreover, global warming influencing the abiotic factors of diffusion and mobility of POPs has led to a massive revolatization of POPs in the Arctic as well as an increase in their concentrations in large mammals. We also noted a lack of availability of consistent and continuous long-term data in Antarctic, which is why an ambiguity persists in the understanding of the POPs contamination routes, their evolution as well as the application of projection models.

“…Re-emission of POPs such as PCPs and PCDD/Fs from glaciers has already been observed, with the highest concentrations measured in the vicinity of marine-terminating glaciers. Thus, ocean warming has a direct influence (Kobusi ńska et al 2020). The gradual decrease or even slight increase in HCB levels in Artic air and ringed seals might also be caused by re-emission (Rigét et al 2020).…”

From 2004 to 2017 he was a member and chair of the Committee of Directors. He is a fisheries biologist trained at Bochum, Hamburg and Kiel University and has worked in Antarctica, Argentina, and the Azores. Since 1991 his work has revolved around fish biology and ecology in tropical ecosystems and throughout the 1990s he was a coordinator for the bilateral co-operation in Marine Research between Brazil and Germany. His research interests lie in the wider field of "Adaptations of different life stages of fish to their environment and the consequences of climate change". This includes activities in growth and population dynamics; migration pattern of fish in coastal environments; ichthyoplankton; fisheries biology; ecology; and ecosystem responses to climate change. An important topic is his work is the ecosystem approach to fisheries management, by which he engaged for many years in the Large Marine Ecosystem community as well as the stimulation and enforcement of international cooperation and networking in marine science and governance. He is a member of the Group of Experts on Capacity Development of the Intergovernmental Oceanographic Commission of UNESCO.
