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

A Critical Review of the \u3csup\u3e15\u3c/sup\u3eN\u3csub\u3e2\u3c/sub\u3e Tracer Method to Measure Diazotrophic Production in Pelagic Ecosystems

Dinitrogen (N2) fixation is an important source of biologically reactive nitrogen (N) to the global ocean. The magnitude of this flux, however, remains uncertain, in part because N2 fixation rates have been estimated following divergent protocols and because associated levels of uncertainty are seldom reported—confounding comparison and extrapolation of rate measurements. A growing number of reports of relatively low but potentially significant rates of N2 fixation in regions such as oxygen minimum zones, the mesopelagic water column of the tropical and subtropical oceans, and polar waters further highlights the need for standardized methodological protocols for measurements of N2 fixation rates and for calculations of detection limits and propagated error terms. To this end, we examine current protocols of the 15N2 tracer method used for estimating diazotrophic rates, present results of experiments testing the validity of specific practices, and describe established metrics for reporting detection limits. We put forth a set of recommendations for best practices to estimate N2 fixation rates using 15N2 tracer, with the goal of fostering transparency in reporting sources of uncertainty in estimates, and to render N2 fixation rate estimates intercomparable among studies

Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are measured. Here, we use a pest-control database encompassing 132 studies and 6,759 sites worldwide to model natural enemy and pest abundances, predation rates, and crop damage as a function of landscape composition. Our results showed that although landscape composition explained significant variation within studies, pest and enemy abundances, predation rates, crop damage, and yields each exhibited different responses across studies, sometimes increasing and sometimes decreasing in landscapes with more noncrop habitat but overall showing no consistent trend. Thus, models that used landscape-composition variables to predict pest-control dynamics demonstrated little potential to explain variation across studies, though prediction did improve when comparing studies with similar crop and landscape features. Overall, our work shows that surrounding noncrop habitat does not consistently improve pest management, meaning habitat conservation may bolster production in some systems and depress yields in others. Future efforts to develop tools that inform farmers when habitat conservation truly represents a win–win would benefit from increased understanding of how landscape effects are modulated by local farm management and the biology of pests and their enemies

The Intersectional Influences of Prince: A Human-Animal Tribute

Prince Rogers Nelson (1958-2016) was best known for his joyful funk music and electrifying stage performances that transgressed normative representations of gender, sexuality, race, spirituality, identity and taste. He was also a compassionate person who held deep convictions about freedom and the right of all species to enjoy lives without fear and suffering. This essay discusses Prince’s intersectional influences – the various ways his virtuosity over the past 38 years disrupted binaries, challenged assumptions and stereotypes, advocated for social justice, and combatted speciesism in its many forms. Embedded within the essay are seven personal tributes written by fans of Prince who are also animal activists and/or scholars in Critical Animal Studies. These ‘memorial solos’ convey how, for each contributor, Prince’s music, image, performativity, compassion and empathy inspired animal advocacy in everyday life

Persona Non Grata

This essay tells the story of the authors’ relationship with a rescued marsupial raised from a baby in Aotearoa New Zealand, in sections interspersed with an account of this species’ history in our country. This animal belongs to a species designated a noxious pest here, a population subject to an especially sustained, thorough, and popularly-supported campaign of vilification and destruction, even by the standards that apply in New Zealand, where the dominant environmental ideology is very intensely focussed on eradication of introduced species. So in deciding to take responsibility for this creature, the authors committed to keeping her both hidden and captive. This raises some intractable questions: is it in this animal’s best interests to be enclosed, or should she be allowed to take her chances on the roads and amongst the traps and poison? how can her captors offer her the best life? what relationship should they have with her? The essay also describes the intimate relationship the two authors have developed with this animal, through nightly interaction, and touches on some of the phenomenological questions she presents: what might it be like to be an arboreal, nocturnal, marsupial mammal instead of a terrestrial, diurnal, placental one? What might it be like to have four legs (or perhaps five, if we count the extraordinary prehensile tail) that are simultaneously arms, rather than two arms and two legs? In New Zealand the overwhelming hostility to this species makes it nearly impossible to recognize or consider its members as living sentient beings. Our primary aim in this essay, therefore, is to convey as directly as possible the emotional and physical experience of being in relationship with this particular animal, while succinctly situating that experience within a relevant environmental context. We didn’t want to use this animal’s story merely as a pretext for exploring larger histories or topics in human-animal studies. For this reason we have chosen the genre of creative nonfiction, and refrained from engaging with discussions by human-animal studies scholars that would be required in a research article

Framing Possums: War, sport and patriotism in depictions of brushtail possums in New Zealand print media

There is a common saying in Aotearoa New Zealand: ‘the only good possum is a dead possum’. This colloquialism demonstrates much about the negative reputation and maltreatment of brushtail possums in New Zealand. Introduced to this country from their native Australia in the 1800s, possums thrived in their new predator-free environment. Possums\u27 adaptability has since proved to be problematic, not least for the nation\u27s lucrative meat and dairy industries. In the past few decades a concerted campaign mounted by the New Zealand government has targeted possums as ruthless pests, demonizing these marsupials to the extent that international tourists are even advised to swerve while driving on the country\u27s roads in order to hit and kill these animals. This paper examines how the print news media in New Zealand frames possums in a way that helps to sustain and encourage violence towards these marsupials. We argue that print media in New Zealand promote an overwhelmingly negative representation of possums which influences cultural understandings and public attitudes – ultimately reproducing and reinforcing hatred, disrespect and maltreatment of possums as pests warranting extermination and undeserving of compassion
