Fathom

[Extract] Terrestrial, bipedal, air breathing, and poorly waterproofed, how can humans fathom the bottom of the sea? This article was composed by an anthropologist, a cultural theorist, a philosopher, a coastal geographer, a cultural geographer, a feminist studies scholar, an artist, a spatial scientist, an ecocritic, a free diver, an STS scholar, a spear fisher, a biologist, a marine ecologist, a poet, a dancer, and a swimmer. (If the math does not add up, we remind you that we are always more than one.) Our insights emerged from a one-day workshop at Clovelly Beach in Sydney, Australia, on land and in the water, where we shared our perspectives and practices in researching ocean environments. Our collaboration is an experiment in multidisciplinary practice-based inquiry, where differences and tensions need not preclude collaborative understanding. In this article we combine emerging critical ocean studies and blue humanities perspectives to propose fathoming as a vital, embodied practice that gathers technoscientific acts of measurement together with practices of immersion, imagination, and speculation. Through collaborative multi-situated inquiry1 we learn new things not only about the sea but also about the limits of epistemological mastery and the rewards of knowing with

A sustainable campus: The Sydney Declaration on interspecies sustainability

Under the remit of an expanded definition of sustainability – one that acknowledges animal agriculture as a key carbon intensive industry, and one that includes interspecies ethics as an integral part of social justice – institutions such as Universities can and should play a role in supporting a wider agenda for sustainable food practices on campus. By drawing out clear connections between sustainability objectives on campus and the shift away from animal based products, the objective of this article is to advocate for a more consistent understanding and implementation of sustainability measures as championed by university campuses at large. We will draw out clear connections between sustainability objectives on campus and the shift away from animal based products. Overall, our arguments are contextualised within broader debates on the relationship between sustainability, social justice and interspecies ethics. We envisage that such discussion will contribute to an enriched, more robust sense of sustainability—one in which food justice refers not only to justice for human consumers and producers of food and the land used by them, but also to justice for the nonhuman animals considered as potential sources of food themselves

Justice Through a Multispecies Lens

The bushfires in Australia during the Summer of 2019–2020, in the midst of which we were writing this exchange, violently heightened the urgency of the task of rethinking justice through a multispecies lens for all of the authors in this exchange, and no doubt many of its readers. As I finish this introduction, still in the middle of the Australian summer, more than 10 million hectares (100,000 km2 or 24.7 million acres) of bushland have been burned and over a billion individual animals killed. This says nothing of the others who will die because their habitat and the relationships on which they depend no longer exist. People all around the world are mourning these deaths and the destruction of unique ecosystems. As humans on this planet, and specifically as political theorists facing the prospect that such devastating events will only become more frequent, the question before us is whether we can rethink what it means to be in ethical relationships with beings other than humans and what justice requires, in ways that mark these deaths as absolute wrongs that obligate us to act, and not simply as unfortunate tragedies that leave us bereft

Genomic signatures of host adaptation in group B Salmonella enterica ST416/ST417 from harbour porpoises

Abstract A type of monophasic group B Salmonella enterica with the antigenic formula 4,12:a:- (“Fulica-like”) has been described as associated with harbour porpoises (Phocoena phocoena), most frequently recovered from lung samples. In the present study, lung tissue samples from 47 porpoises found along the Swedish coast or as bycatch in fishing nets were analysed, two of which were positive for S. enterica. Pneumonia due to the infection was considered the likely cause of death for one of the two animals. The recovered isolates were whole genome sequenced and found to belong to sequence type (ST) 416 and to be closely related to ST416/ST417 porpoise isolates from UK waters as determined by core-genome MLST. Serovars Bispebjerg, Fulica and Abortusequi were identified as distantly related to the porpoise isolates, but no close relatives from other host species were found. All ST416/417 isolates had extensive loss of function mutations in key Salmonella pathogenicity islands, but carried accessory genetic elements associated with extraintestinal infection such as iron uptake systems. Gene ontology and pathway analysis revealed reduced secondary metabolic capabilities and loss of function in terms of signalling and response to environmental cues, consistent with adaptation for the extraintestinal niche. A classification system based on machine learning identified ST416/417 as more invasive than classical gastrointestinal serovars. Genome analysis results are thus consistent with ST416/417 as a host-adapted and extraintestinal clonal population of S. enterica, which while found in porpoises without associated pathology can also cause severe opportunistic infections
