Sub-Antarctic Islands – Sentinels of Change
SCAR OPEN SCIENCE CONFERENCE 2020 SESSION 29 SUB-ANTARCTIC ISLANDS – SENTINELS OF CHANGE Christel Hansen Craig Cary, Justine Shaw, Mia Wege ABSTRACTS SUBMITTED TO THE (CANCELLED) SCAR 2020 OSC IN HOBART 1726 Ecological consequences of a single introduced species to the Antarctic: the invasive midge Eretmoptera murphyi on Signy Island Jesamine C Bartlett1, Pete Convey1, Kevin K Newsham1, Kevin A Hughes1, Scott AL Hayward1 1Norwegian Institute For Nature Research, Trondheim, Norway The nutrient-poor soils of Antarctica are sensitive to change. Ongoing increase in anthropogenically assisted non-native species introductions means that understanding the impact of such species on these soil systems is urgent, and essential for developing future risk assessments and management actions. Through comparative baseline characterisation of vegetation, microbes, soil biochemistry, substrate composition and micro-arthropod abundance, this study explores the impacts that have resulted from the 1960s introduction of the invasive chironomid midge Eretmoptera murphyi to Signy Island in maritime Antarctica. The key finding is that where E. murphyi occurs there has been an increase in inorganic nitrogen availability within the nutrient-poor soils. Concentration of available nitrate is increased three- to five-fold relative to uncolonised soils, and that the soil ecosystem may be impacted through changes in the C:N ratio which can influence decomposition rates and the mircoarthropod community. We also measured the levels of inorganic nitrogen in soils influenced by native marine vertebrate aggregations and found the increase in nitrate availability associated with E. murphyi to be similar to that from seals. We suggest that these changes will only have greater impacts over time, potentially benefitting currently limited vascular plant populations and altering plant and invertebrate communities. -

Aileen was accompanied by her two sons, Cian and Morgan, and her partner Bill Sheppard, with Crag Jones and Stephen Venables as mountain leaders. Although five of the team were successful, an unlucky accident stopped Aileen herself from completing the traverse. !1 SOUTH GEORGIA – CREAN SHACKLETON TRAVERSE 2016 Salvesen and Crean teams at Grytviken The Crean team boarded Pelagic in Stanley on TRAVERSE – DAY 1 – October 8 September 17, reaching South Georgia the We left King Haakon Bay at 05.30, travelling following week.

Species List for Svalbard Birds and Mammals
Falkland Islands Circumnavigation – A South Atlantic bird & wildlife spectacle Falkland Islands There is no other groups of islands in the entire Atlantic Ocean which allows fairly easy access to such a diversity of spectacular bird species under such a mild climate and with such a variety of marine mammals thrown in. The Falkland Islands are known to most people today more for their recent political history than their natural history. And even to many nature lovers, the Falklands are often seen as secondary compared to the neighbouring Antarctica and South Georgia. This voyage aims to set the record straight: The Falkland Islands are worth every minute of a two-week circumnavigation, and they will provide us with a long string of wonderful encounters with penguins (4-5 species), albatrosses, cormorants, ducks and geese, raptors, shore birds, song birds and more – as well as seals and sea lions, whales and dolphins. We will see a variety of the islands’ unique landscapes of rolling hills, stone runs, rugged shorelines, pristine white beaches and lush giant kelp beds. We will see the endemic bird species and several near-endemic ones as well, and we intend to visit the southern hemisphere’s largest albatross colony on Steeple Jason. There will be time enough to allow for prolonged visits to the most magnificent of the sites during the best of the weather conditions. The group will be small enough to allow for great flexibility and individual attention. Tour Description Dates: December 3 - 17, 2016. Price: Starting at US$ 8.500,- Group size: Minimum 8, maximum 11. -

How Seabirds Telecouple the Beagle Channel with Regional and Global Processes That Affect Environmental Conservation and Social-Ecological Sustainability
Copyright © 2017 by the author(s). Published here under license by the Resilience Alliance. Raya Rey, A. N., J. C. Pizarro, C. B. Anderson, and F. Huettmann. 2017. Even at the uttermost ends of the Earth: how seabirds telecouple the Beagle Channel with regional and global processes that affect environmental conservation and social-ecological sustainability. Ecology and Society 22(4):31. https://doi.org/10.5751/ES-09771-220431 Synthesis, part of a Special Feature on Telecoupling: A New Frontier for Global Sustainability Even at the uttermost ends of the Earth: how seabirds telecouple the Beagle Channel with regional and global processes that affect environmental conservation and social-ecological sustainability Andrea N. Raya Rey 1,2, J. Cristobal Pizarro 1,3, Christopher B. Anderson 1,2 and Falk Huettmann 4 ABSTRACT. Human-wildlife dynamics exhibit novel characteristics in the Anthropocene, given the unprecedented degree of globalization that has increased the linkages between habitats and people across space and time. This is largely caused by transnational mobility and migration, international labor, resource markets, and trade. Understanding the relationship between humans and wildlife, and their associated telecoupling processes, helps to promote better management practices and governance for reconciling socioeconomic and conservation interests. Even remote places on the globe exhibit these features. For example, in southern Patagonia’s coastal and marine ecosystems, seabirds are not only very abundant and charismatic members of the wildlife community, nowadays, their colonies are a main tourism attraction of global significance, and in the past they were used for consumptive and scientific purposes that also linked the “uttermost ends of the Earth” with distant places.
