“…The total number of species in various groups of macroepifauna in the methodologically standardized studies was higher in the Antarctic (Piepenburg et al, 1997;Starmans et al, 1999;Starmans & Gutt, 2002) while regional (Sirenko, 2001;De Broyer et al, 2011) and local (Weddell Sea vs Lazarev Sea) (Sirenko, 2009) comparisons of species lists showed similar species richness in both polar regions. It might suggest that some of the Arctic taxa have a higher share of rare species.…”

“…Recent taxonomic inventories of both polar regions demonstrated that in general the number of species is similar. De Broyer et al (2011) listed 5,800 benthic species in the Southern Ocean, while the number of Arctic species was estimated to be about 4,800 (Sirenko, 2001;Piepenburg et al, 2011). Moreover, some studies suggested that both Arctic and Antarctic diversity are still underestimated (e.g., Carr, 2012;Pabis et al, 2014).…”

Distinct or similar? Soft bottom polychaete diversity in Arctic and Antarctic glacial fjords

2014

The main aim of this study was to compare the polychaete communities in two similar polar areas: an Arctic fjord, Hornsund (Svalbard) and an Antarctic fjord, Ezcurra Inlet (South Shetlands). This is the first attempt to compare Arctic and Antarctic diversity based on fully comparable datasets. Forty van Veen grab samples were collected in each fjord: twenty replicates were taken in each of two fjord areas characterized by a different level of glacial disturbance-in the inner (glacial bay) and outer (fjord mouth) region of both fjords, from depths of about 100 m in 2005 (Hornsund) and in 2007 (Ezcurra Inlet). In the glacial bays, species richness and diversity were significantly higher in Ezcurra Inlet than in Hornsund due to higher rate of glacial disturbance in the latter one. In the outer areas, species richness was similar in both fjords, although diversity values were higher in Ezcurra Inlet. Polychaete species richness in the habitats characterized by similar level of disturbance (outer areas of the fjords) was the same in both polar regions. At this small scale, where community drivers are very similar, the species richness seems to be independent from the local or regional species pool.

“…For this reason early predictions suggested that the majority of benthic fauna within Antarctic waters would be endemic to the Southern Ocean (Ekman, 1953;Hedgpeth, 1969). Endemism has since been observed in many major taxonomic groups based on species records from mostly morphological species identification (see reviews Dell, 1972;Arntz et al, 1997;Clarke and Johnston, 2003;Thorpe et al, 2007;De Broyer and Danis, 2011;Brandt et al, 2012;Kaiser et al, 2013).…”

Distributional Patterns of Polychaetes Across the West Antarctic Based on DNA Barcoding and Particle Tracking Analyses

et al. 2017

Recent genetic investigations have uncovered a high proportion of cryptic species within Antarctic polychaetes. It is likely that these evolved in isolation during periods of glaciation, and it is possible that cryptic populations would have remained geographically restricted from one another occupying different regions of Antarctica. By analysing the distributions of nine morphospecies, (six of which contained potential cryptic species), we find evidence for widespread distributions within the West Antarctic. Around 60% of the cryptic species exhibited sympatric distributions, and at least one cryptic clade was found to be widespread. Additional DNA barcodes from GenBank and morphological records extended the observed range of three species studied here, and indicate potential circum-Antarctic traits. Particle tracking analyses were used to model theoretical dispersal ranges of pelagic larvae. Data from these models suggest that the observed species distributions inferred from genetic similarity could have been established and maintained through the regional oceanographic currents, including the Antarctic Circumpolar Current (ACC) and its coastal counter current. Improved understanding of the distribution of Antarctic fauna is essential for predicting the impacts of environmental change and determining management strategies for the region.

“…Furthermore, the decision makers do not really need data at all but rather information presented in compelling, readily interpretable ways. Effective data and information display can encourage greater data sharing, increase understanding of complex processes, and enable wiser decisions [45][46][47][48].…”

Much attention has been given to the challenges of handling massive data volumes in modern data-intensive science. This paper examines an equally daunting challenge -the diversity of interdisciplinary data, notably research data, and the need to interrelate these data to understand complex systemic problems such as environmental change and its impact. We use the experience of the International Polar Year 2007-8 (IPY) as a case study to examine data management approaches seeking to address issues around complex interdisciplinary science. We find that, while technology is a critical factor in addressing the interdisciplinary dimension of the data intensive science, the technologies developing for exa-scale data volumes differ from those that are needed for extremely distributed and heterogeneous data. Research data will continue to be highly heterogeneous and distributed and will require technologies to be much simpler and more flexible. More importantly, there is a need for both technical and cultural adaptation. We describe a vision of discoverable, open, linked, useful, and safe collections of data, organized and curated using the best principles and practices of information and library science. This vision provides a framework for our discussion and leads us to suggest several short-and long-term strategies to facilitate a socio-technical evolution in the overall science data ecosystem.
