- Understanding and predicting patterns of spatial organization across ecological communities is central to the field of landscape ecology, and a similar line of inquiry has begun to evolve sub-tidally among seascape ecologists. Much of our current understanding of the processes driving marine community patterns, particularly in the tropics, has come from small-scale, spatially-discrete data that are often not representative of the broader seascape. Here we expand the spatial extent of seascape ecology studies and combine spatially-expansive in situ digital imagery, oceanographic measurements, spatial statistics, and predictive modeling to test whether predictable patterns emerge between coral reef benthic competitors across scales in response to intra-island gradients in physical drivers. We do this around the entire circumference of a remote, uninhabited island in the central Pacific (Jarvis Island) that lacks the confounding effects of direct human impacts. We show, for the first time, that competing benthic groups demonstrate predictable scaling patterns of organization, with positive autocorrelation in the cover of each group at scales < similar to 1 km. Moreover, we show how gradients in subsurface temperature and surface wave power drive spatially-abrupt transition points in group dominance, explaining 48-84% of the overall variation in benthic cover around the island. Along the western coast, we documented ten times more sub-surface cooling-hours than any other part of the coastline, with events typically resulting in a drop of 1-4 degrees C over a period of < 5 h. These high frequency temperature fluctuations are indicative of upwelling induced by internal waves and here result in localized nitrogen enrichment (NO2 + NO3) that promotes hard coral dominance around 44% of the island's perimeter. Our findings show that, in the absence of confounding direct human impacts, the spatial organization of coral reef benthic competitors are predictable and somewhat bounded across the seascape by concurrent gradients in physical drivers.

- Purpose The purpose of this paper is to interrogate the nature and relevance of debates around the existence of, and ramifications arising from, the Anthropocene for accounting scholarship. Design/methodology/approach The paper's aim is achieved through an in-depth analysis of the Anthropocene, paying attention to cross-disciplinary contributions, interpretations and contestations. Possible points of connection between the Anthropocene and accounting scholarship are then proposed and illuminated through a case study drawn from the seafood sector. Findings This paper develops findings in two areas. First, possible pathways for further development of how accounting scholarship might evolve by the provocation that thinking about the Anthropocene is outlined. Second, and through engagement with the case study, the authors highlight that the concept of stewardship may re-emerge in discussions about accountability in the Anthropocene. Social implications Human well-being is likely to be impacted if environmental impacts accelerate. In addition, an Anthropocene framing alters the understanding of nature-human interactions and how this affects accounting thought. Originality/value This is the first paper in accounting to seek to establish connections between accounting, accountability and the Anthropocene.

- Transnational companies have substantive impacts on nature: a hallmark of living in the Anthropocene. Understanding these impacts through company provision of information is a precursor to holding them accountable for nature outcomes. The effect of increasing disclosures (of varying quality) is predicated on 'information governance', an approach that uses disclosure requirements to drive company behaviour. However, its efficacy is not guaranteed. We argue that three conditions are required before disclosures have the possibility to shape nature outcomes, namely: (1) radical traceability that links company actions to outcomes in particular settings; (2) developing organizational routines, tools and approaches that translate strategic intent to on-the-ground behaviour; and (3) mobilizing and aligning financial actors with corporate nature ambitions. While disclosure is key to each of these conditions, its limits must be taken into account and it must be nested in governance approaches that shape action, not just reporting.This article is part of the theme issue 'Bringing nature into decision-making'.

The shape of success in a turbulent world : wave exposure filtering of coral reef herbivory

- While environmental filters are well-known factors influencing community assembly, the extent to which these modify species functions, and entire ecosystem processes, is poorly understood. Focusing on a high-diversity system, we ask whether environmental filtering has ecosystem-wide effects beyond community assembly. We characterise a coral reef herbivorous fish community for swimming performance based on ten functional traits derived from fish morphology. We then investigate whether wave exposure modifies the functional make-up of herbivory, and the absolute and relative feeding frequency of distinct feeding functional groups. Herbivorous fish species conformed to either laterally compressed or fusiform body plans, which differ in their morphological design to minimise drag. High wave exposure selectively limited the feeding function of the deepest body shapes with highest caudal thrust efficiency, and favoured fusiform bodies irrespective of pectoral fin shape. Traditionally recognised herbivore feeding functional groups (i.e. grazers-detritivores and scrapers-small excavators) differed in swimming performance, and in their capacity to feed consistently across levels of wave exposure. We therefore emphasise the distinctness of their ecological niche and functional complementarity. Species within the same feeding functional group also had contrasting responses to wave exposure. We thereby reveal a further ecological dimension of niche partitioning, and reiterate the risk of assuming functional redundancy among species with a common feeding mode. Contrasting responses of species within feeding functional roles (i.e. response diversity) allowed the preservation of critical trophic functions throughout the gradient (e.g. macroalgal browsing), and likely explained why overall levels of herbivory were robust to filtering. Whether ecosystem functioning will remain robust under the additive effects of environmental stress and human-induced disturbances remains to be tested.

Corporate control and global governance of marine genetic resources
- 2018

Ingår i: Science Advances. - : American Association for the Advancement of Science (AAAS). - 2375-2548. ; 4:6
-
Tidskriftsartikel (refereegranskat)abstract
- Who owns ocean biodiversity? This is an increasingly relevant question, given the legal uncertainties associated with the use of genetic resources from areas beyond national jurisdiction, which cover half of the Earth's surface. We accessed 38 million records of genetic sequences associated with patents and created a database of 12,998 sequences extracted from 862 marine species. We identified >1600 sequences from 91 species associated with deepsea and hydrothermal vent systems, reflecting commercial interest in organisms from remote ocean areas, as well as a capacity to collect and use the genes of such species. A single corporation registered 47% of all marine sequences included in gene patents, exceeding the combined share of 220 other companies (37%). Universities and their commercialization partners registered 12%. Actors located or headquartered in 10 countries registered 98% of all patent sequences, and 165 countries were unrepresented. Our findings highlight the importance of inclusive participation by all states in international negotiations and the urgency of clarifying the legal regime around access and benefit sharing of marine genetic resources. We identify a need for greater transparency regarding species provenance, transfer of patent ownership, and activities of corporations with a disproportionate influence over the patenting of marine biodiversity. We suggest that identifying these key actors is a critical step toward encouraging innovation, fostering greater equity, and promoting better ocean stewardship.

Corporations and plastic pollution : Trends in reporting
- 2021
-
Ingår i: Sustainable Futures. - : Elsevier BV. - 2666-1888. ; 3
-
Tidskriftsartikel (refereegranskat)abstract
- Research on pathways to reducing plastic pollution often concludes that greater action is needed by the private sector. Yet the private sector is not a monolithic or homogeneous entity. We compiled a novel library of 2,317 corporate reports from the world's 200 largest companies, by revenue, over a ten-year period (2010–2019) and used text mining tools to identify pronounced regional and sectoral variability in the extent to which plastic waste and pollution is of material importance to corporate operations. The results show a dominant focus on recycling, with far less attention to the other stages of the life cycle of plastic. While green clubs have emerged in recent years to mobilize voluntary actions by companies seeking to position themselves as leaders in this context, we see regional and sectoral gaps in green club membership, as well as a tendency for members to be those companies that already had a history of reporting on plastics issues. This analysis provides a starting point for a more nuanced consideration of the private sector's role in addressing plastic pollution, and suggests sectors and regions for prioritization by policymakers and civil society actors seeking to broaden the range of committed corporate actors.

Evolving Perspectives of Stewardship in the Seafood Industry
- 2021
-
Ingår i: Frontiers in Marine Science. - : Frontiers Media SA. - 2296-7745. ; 8

Tidskriftsartikel (refereegranskat)abstract
- Humanity has never benefited more from the ocean as a source of food, livelihoods, and well-being, yet on a global scale this has been accompanied by trajectories of degradation and persistent inequity. Awareness of this has spurred policymakers to develop an expanding network of ocean governance instruments, catalyzed civil society pressure on the public and private sector, and motivated engagement by the general public as consumers and constituents. Among local communities, diverse examples of stewardship have rested on the foundation of care, knowledge and agency. But does an analog for stewardship exist in the context of globally active multinational corporations? Here, we consider the seafood industry and its efforts to navigate this new reality through private governance. We examine paradigmatic events in the history of the sustainable seafood movement, from seafood boycotts in the 1970s through to the emergence of certification measures, benchmarks, and diverse voluntary environmental programs. We note four dimensions of stewardship in which efforts by actors within the seafood industry have aligned with theoretical concepts of stewardship, which we describe as (1) moving beyond compliance, (2) taking a systems perspective, (3) living with uncertainty, and (4) understanding humans as embedded elements of the biosphere. In conclusion, we identify emerging stewardship challenges for the seafood industry and suggest the urgent need to embrace a broader notion of ocean stewardship that extends beyond seafood.

The Ocean Decade as an instrument of peace

Ingår i: Current Opinion in Environmental Sustainability. - 1877-3435 .- 1877-3443. ; 64
-
Tidskriftsartikel (refereegranskat)abstract
- The United Nations Decade of Ocean Science for Sustainable Development 2021-2030 (the 'Ocean Decade') is poised to stimulate new cooperation for ocean science, but makes no mention of conflict or peace. We contend that this is a missed opportunity, and use an environmental peacebuilding typology to review how ocean science has historically contributed to peace. Such considerations are timely in the context of an increasingly complex and multidimensional ocean risk landscape, due among other things to unprecedented growth in the extent and intensity of ocean uses, and increasing conflict potential as the ocean becomes a more crowded and coveted place. We conclude by proposing the Ocean Decade Implementation Plan be appended to include an eighth intended outcome: 'A Peaceful Ocean'.

Sharing the seas : a review and analysis of ocean sector interactions

Forskningsöversikt (refereegranskat)abstract
- Ocean activities are rapidly expanding as Blue Economy discussions gain traction, creating new potential synergies and conflicts between sectors. To better manage ocean sectors and their development, we need to understand how they interact and the respective outcomes of these interactions. To provide a first comprehensive picture of the situation, we review 3187 articles to map and analyze interactions between economically important ocean sectors and find 93 unique direct and 61 indirect interactions, often mediated via the ocean ecosystem. Analysis of interaction outcomes reveals that some sectors coexist synergistically (e.g. renewable energy, tourism), but many interactions are antagonistic, and negative effects on other sectors are often incurred via degradation of marine ecosystems. The analysis also shows that ocean ecosystems are fundamental for supporting many ocean sectors, yet 13 out of 14 ocean sectors have interactions resulting in unidirectional negative ecosystem impact. Fishing, drilling, and shipping are hubs in the network of ocean sector interactions, and are involved in many of the antagonistic interactions. Antagonistic interactions signal trade-offs between sectors. Qualitative analysis of the literature shows that these tradeoffs relate to the cumulative nature of many ecosystem impacts incurred by some sectors, and the differential power of ocean sectors to exert their rights or demands in the development of the ocean domain. There are also often time lags in how impacts manifest. The ocean governance landscape is not currently well-equipped to deal with the full range of trade-offs, and opportunities, likely to arise in the pursuit of a Blue Economy in a rapidly changing ocean context. Based on our analysis, we therefore propose a set principles that can begin to guide strategic decision-making, by identifying both tradeoffs and opportunities for sustainable and equitable development of ocean sectors.
