title: An Antarctic hot spot for Fungi at Shackleton's Historic Hut on Cape Royds

authors: Blanchette, Robert A.

subjects: Antarctic

abstract: The historic expedition huts located in the Ross Sea Region of the Antarctic and the thousands of artifacts left behind by the early explorers represent important cultural heritage from the “Heroic Era” of Polar exploration. The hut at Cape Royds built by Ernest Shackleton and members of the 1907–1908 British Antarctic Expedition has survived the extreme Antarctic environment for over 100 years, but recent studies have shown many forms of deterioration are causing serious problems, and microbial degradation is evident in the historic wood. Conservation work to reduce moisture at the hut required removal of fodder, wood, and many different types of organic materials from the stables area on the north side of the structure allowing large numbers of samples to be obtained for these investigations. In addition, wood from historic food storage boxes exposed in a ravine adjacent to the hut were also sampled. Fungi were cultured on several different media, and pure cultures were obtained and identified by sequencing of the internal transcribed spacer region of rDNA. From the 69 cultures of filamentous fungi obtained, the most predominant genera were Cadophora (44%) followed by Thielavia (17%) and Geomyces (15%). Other fungi found included Cladosporium, Chaetomium, and isolates identified as being in Pezizomycotina, Onygenales, Nectriaceae, and others. No filamentous basidiomycetes were found. Phylogenetic analyses of the Cadophora species showed great species diversity present revealing Cadophora malorum, Cadophora luteo-olivacea, Cadophora fastigiata, as well as Cadophora sp. 4E71-1, a C. malorum-like species, and Cadophora sp. 7R16-1, a C. fastigiata-like species. Scanning electron microscopy showed extensive decay was present in the wood samples with type 1 and type 2 forms of soft rot evident in pine and birch wood, respectively. Fungi causing decay in the historic wooden structures and artifacts are of great concern, and this investigation provides insight into the identity and species diversity of fungi found at the site. The historic woods and other organic materials at this site represent a large input of carbon into the Antarctic environment. This as well as nutrient additions from the nearby Adélie penguin (Pygoscelis adeliae) colony and favorable conditions for fungal growth at Cape Royds appear responsible for the significant fungal diversity, and where extensive decay is taking place in wood in contact with the ground.

title: Marketing in the Flourishing Society Megatrend

authors: Varey, Richard J.

subjects: post-industrial business

abstract: “New science” has profound implications for business. Industrial capitalism can no longer power prosperity. The mass society worldview is giving way to individualisation. The “standard enterprise logic” is challenged. Marketing has operated as an attention technology for sellers competing to capture customers. However, in an intention economy buyers are a scarce commodity, and it is intentions that drive production for specific needs. Change in marketing is overdue. Despite increased social disharmony and the mounting evidence of looming environmental disasters, progress is stagnant, often negative, as marketing exacerbates the problem by misallocating negative value goods. The commonality in the contemporary crises of financial meltdown, human-made climate change, economic inequality, distrust of government, and the social corrosion of consumerism is the moral limits of markets in civic society. Sustainable living provides the higher purpose of marketing: well-being and human flourishing. Sustainability is a socio-cultural, inherently ethical, respectful, intellectual construct for a life of careful and equitable resource use within limits and inter-dependencies. It is not the antithesis of competitive business, indeed business can flourish by competing on, and being rewarded for, the accomplishment of enduringly valuable outcomes. Sustainability is a transcendent societal “mega”-megatrend.

title: Marine inequality, borderization, and the radical potential of kinship

authors: McCormack, Fiona

subjects: Aquaculture

abstract: This article utilizes scholarship on borders to interpret the persistence of inequality in Indigenous seascapes, irrespective of moves to redress colonial wrongs or the growing anthropocenic recognition of human-nature interconnectedness. I examine border politics in the context of Māori claims for marine title and rights and the post-settlement development of aquaculture. Drawing on Harsha Walia’s concept of “border imperialism” and Achille Mbembe’s thesis on “borderization,” the article highlights the endurance of colonial forms alongside their neoliberal transformation into the enclosures and entrapments arising in the context of accelerated marine industrialization. By holding in tension the interconnection between marine environments and kinship, on one hand, and scholarship on borders, on the other, the article suggests that Indigenous Māori kinship, expanding through multiple layers of difference, constitutes a site of resistance that has the potential to refute the logic of borderization.
