The generation and radial structure of zonal flows are studied in competing collisional drift waves and interchange turbulence using the reduced flux-driven nonlinear model Tokam1D. Zonal flows are generated in both the interchange dominated and adiabatic regimes with the former favoring radially structured flows and avalanche transport. The distance to the instability threshold proves to be key, with a more stable radial flow structure emerging near the threshold and increased energy stored in the flows for interchange turbulence. The avalanches are shown to perturb zonal flow structures in drift-wave turbulence and to reactivate them in the interchange regime. Finally, the ExB staircases with radially structured, stable in time zonal flows are proved beneficial for the overall confinement.

The alfalfa weevil Hypera postica Gyllenhal (Coleoptera: Curculionidae) is one of the most destructive alfalfa pests in the world, resulting in substantial economic losses. However, the amount of damage can be reduced by larval parasitoids of the genus Bathyplectes Förster (Hymenoptera: Ichneumonidae) as a conservation biological control strategy. Parasitoids are currently identified by morphological body characteristics, cocoon morphology, and/or DNA analysis, but geometric morphometrics (GM) applied to the wing vein arrangement may also reveal differences between specimens. We distinguished 61 B. anurus (Thomson) and 41 B. curculionis (Thomson) specimens, based on the appearance of the cocoon. GM revealed statistically significant differences in wing vein patterns and fore wing shapes between species, but not between sexes within the same species. The 1 M + 1R1 cell, also known as the horsehead cell, was revealed to be an easy and reliable morphological character for species differentiation. Despite the New World literature, this is the first European report providing a visual method to differentiate B. anurus from B. curculionis. This study highlights the importance of precise species identification methods, such as geometric morphometry. It can contribute to a better implementation of biological control strategies against the alfalfa weevil in Spain and other Mediterranean countries.

The unchecked rise in global plastic production has resulted in widespread pollution and exposure to hazardous chemicals. Over 16,000 chemicals are used across the plastics life cycle, with thousands meeting criteria for persistence, bioaccumulation, mobility and toxicity. Many remain unregulated under existing multilateral environmental agreements. In response, the United Nations Environment Assembly has mandated the development of an international, legally binding instrument to end plastic pollution. Current treaty negotiations have begun addressing a short list of chemicals, yet significant gaps remain. These include insufficient regulatory mechanisms, lack of chemical transparency and reliance on ineffective recycling strategies that reintroduce toxic substances into consumer products. The presence of harmful chemicals in plastics contributes to major public health burdens and is an environmental threat, with high annual costs that reduce the potential for economic development through safer recycling. Vulnerable populations, including children, reproductive-aged individuals, and frontline communities, face heightened risks. To address this, we recommend the following three critical actions for the treaty: (1) globally regulating chemicals of concern based on hazard; (2) mandating transparency of plastic chemical composition and (3) designing plastics using safe-by-design principles and essential-use criteria. Group-based regulation, which would consider categories of related chemicals, should replace individual chemical approaches to prevent regrettable substitutions. Binding, global obligations, rather than fragmented or voluntary measures, are vital for sustainability, chemical safety, circularity and accountability across the plastics life cycle. A strong treaty is a critical opportunity to achieve a safer, more sustainable future for human and environmental health.

In this article, we show that the Russian invasion of Ukraine triggered a pro-democratic reaction from citizens in liberal democracies, which we term the “rally for democracy.” Unlike the conventional “rally ‘round the flag” effect that boosts government popularity, this involves citizens rallying behind democracy as an international ideal. It includes expressing stronger proximity to democratic powers, stronger approval for democratic leaders abroad, and greater aversion to authoritarian regimes. Through a survey quasi-experiment conducted in six countries between February and May of 2022, we provide evidence that the “rally for democracy” emerged immediately following Russia’s invasion. Exploring this observation further via analysis of data from 55 countries between 2014 and 2023, we find this to be the intensification of a longer-term trend in response to the rise of authoritarian great powers. A new cleavage exists in geopolitical loyalties, based on the degree to which citizens feel attachment to democracy, and this divide runs both between and within countries.

Detection approaches based on environmental DNA (eDNA) are widely used for free-living species but remain underutilized for parasite species. This study applies eDNA detection methods to elucidate the life cycle of the trematode Curtuteria arguinae, which infects the socioeconomically and ecologically important edible cockle (Cerastoderma edule) as its second intermediate host along the northeastern Atlantic coast, including Arcachon Bay, France. The first intermediate and definitive hosts remained unknown. To identify these hosts – presumed to be a gastropod and a shorebird – we developed a quantitative PCR (qPCR)-based eDNA approach targeting partial cox1 and SSU gene regions of C. arguinae. We tested for C. arguinae eDNA presence in water samples containing separately five dominant gastropod species and fecal samples from known cockle predators, the European oystercatcher (Haematopus ostralegus) and gulls (Larus spp.), collected in Arcachon Bay. C. arguinae eDNA was only detected in water containing the needle snail (Bittium reticulatum), with cercarial emergence confirming infection in 1.6% of individual hosts. Morphological analysis of the cercarial and metacercarial stages revealed variability in collar spine visibility. Additionally, C. arguinae was detected by qPCR in 42% of oystercatcher feces and no gull feces, suggesting oystercatchers are the definitive host. This study is the first to elucidate the complete life cycle of C. arguinae, identifying B. reticulatum as its first intermediate host and H. ostralegus as its definitive host. Our findings highlight the potential of eDNA approaches for resolving parasite life cycles and enabling advances in ecological research on C. arguinae.

The Five Domains model (FDM) is a widely accepted framework for developing welfare assessment tools across various contexts, including wild animals under human care. However, only two protocols have been developed for captive cetaceans. This study aimed to create a welfare assessment protocol based on the FDM for captive Yangtze finless porpoises (YFPs; Neophocaena asiaeorientalis asiaeorientalis). Indicators relevant to YFPs’ welfare were selected via a literature review, and validated through two consecutive questionnaire surveys, four discussions with a panel of three experts, and a blind review conducted by three additional cetacean welfare experts. This process resulted in the validation of 46 welfare indicators, which were used to develop the Yangtze Finless Porpoise-Welfare Assessment Protocol (YFP-WAP) which, in its final version, contains 150 indicators. Moreover, intensity levels (the degree of impact of each indicator on the porpoises’ welfare), valence (whether the indicator contributed positively or negatively to the porpoises’ welfare state), and mental states associated with each indicator were also assigned by the panels of experts. Additionally, a confidence score was assigned to each indicator’s intensity level, valence, and mental state that reflected experts’ level of uncertainty regarding the indicator impact on the YFPs’ welfare. This rigorous validation process provided transparency, helped ensure minimal bias, and reduced the likelihood of incorrect indicator elimination due to expert subjectivity. By integrating expert knowledge, the YFP-WAP provides a comprehensive approach to evaluating both positive and negative welfare states, supporting the ongoing care and management of YFPs in captivity.

Tokenised assets are expected to transform finance, yet their legal treatment remains a source of uncertainty. This article presents an analytical framework for categorising legal structures of tokenised assets, addressing a gap in academic literature and regulatory approaches. We introduce a taxonomy based on the legal relationship between tokens and their underlying assets. In complete tokenisation tokens embody legally enforceable rights. It comprises direct tokenisation, where tokens are the primary form of the asset, and indirect tokenisation, where asset-backed tokens are created through intermediary structures. In contrast, incomplete tokenisation results in tokens that function as “digital twins” with limited or no legal value.

Our analysis reveals that the effectiveness of tokenisation depends on the robustness of this legal bond. We compare how these categories impact tokenisation features, including asset transferability, legal certainty, and composability. Furthermore, we identify limiting factors in current regulatory frameworks, such as form requirements, ownership models, and identity mechanisms. Drawing examples from various legal systems and asset classes, including financial instruments, property rights, and digital assets, this work provides a foundation for evaluating tokenisation strategies, with practical insights for regulators and market participants.

Regional climate models (RCMs) are fundamental tools in understanding and quantifying the contribution of the Greenland ice sheet to sea-level rise. We perform an extensive evaluation of the daily air temperature simulated by two RCMs, MARv3.12 and RACMO$2.3\text{p}2$, and a global atmospheric reanalysis, ERA5, at 35 locations across the ice sheet over the period 1995–2020. We compare model results to weather station data from two climate networks, focusing on the spatial and temporal variability in mean biases (MBs). All three models perform well at low elevations (<1500 m a.s.l.) with an MB of 0.16∘C (MAR), $0.36^{\circ}\mathrm{C}$ (RACMO) and $0.41^{\circ}\mathrm{C}$ (ERA5), while warm biases (>1.70$^{\circ}\mathrm{C}$) are found at high elevations (>1500 m a.s.l.). Temperature biases exhibit a strong seasonality, being more pronounced during winter and much smaller during summer ranging from $0.11^{\circ}\mathrm{C}$ to $0.59^{\circ}\mathrm{C}$. No interannual variability is found in the biases of all three datasets. Daily variability within each month is captured well by both climate models and the reanalysis at most locations. Finally, all three models perform overall better in the ablation zone during summer, i.e. where and when considerable melt production occurs.

Anisakis pegreffii and A. simplex (s.s.) are the two zoonotic anisakids infecting cetaceans as well as pelagic/demersal fish and squids. In European waters, A. pegreffii prevails in the Mediterranean Sea, while A. simplex (s.s.) in the NE Atlantic Ocean. Abiotic conditions likely play a significant role in shaping their geographical distribution. The Iberian Atlantic and Alboran Sea waters are sympatric areas of the two species. A total of 429 adults and L3 stage from both sympatric and allopatric areas were studied by a wide nuclear genotyping approach (including newly and previously found diagnostic single nucleotide polymorphisms (SNPs) at nuclear DNA (nDNA) and microsatellite DNA loci) and sequenced at mitochondrial DNA (mtDNA) cox2. Admixture between the two species was detected in the sympatric areas studied by STRUCTURE Bayesian analysis; NEWHYBRIDS revealed different categories of hybridization between the two species, representing approximately 5%. A tendency for F1 female hybrids to interbreed with the parental species at the geographical distribution limits of both species was observed. This finding suggests that hybridization occurs when the two parental species significantly differ in abundance. Mitochondrial introgression of A. simplex (s.s.) in A. pegreffii from Mediterranean waters was also detected, likely as a result of past and/or paleo-introgression events. The high level of genetic differentiation between the two species and their backcrosses indicates that, despite current hybridization, reproductive isolation which maintains evolutionary boundaries between the two species, exists. Possible causes of hybridization phenomena are attempted, as well as their evolutionary and ecological implications, also considering a sea warming scenario in European waters.

Discussions of the difference between Indigenous and Western legal systems, and the subsequent potential weaving of the two, have become a focus of Aotearoa New Zealand (NZ) law academics and practitioners in recent years. Furthermore, industrial relations may have the potential to further some of this weaving within the world of work. This paper explores the weaving of tikanga Māori (Māori legal systems) and English-derived state law within Aotearoa NZ workplace personal grievance processes, by explaining the meaning of tikanga Māori concepts and their potential application to workplace personal grievance processes. It asks: what is the tikanga Māori take–utu–ea (∼cause–reciprocation–satisfaction) framework in relation to workplace personal grievances? What role could such a framework potentially have in ensuring reciprocal, mana (status)-enhancing approaches for personal grievance processes? This paper shows how current workplace personal grievance processes in Aotearoa NZ often produce ‘winners’ and ‘losers’, and such outcomes are not conducive to maintaining or improving employment relationships. Such processes not only uphold obligations and duties to Indigenous peoples in a workplace context but also improve outcomes for all working peoples. Overall, this paper contributes to an emerging, broader discussion about the world of work and current grievance systems, and how these are unsuitable for the modern era, concluding that Indigenous solutions offer much prospect.

During the coronavirus pandemic in the United Kingdom, media outlets shifted their focus from divisive political issues to more neutral topics like lifestyle, sports, and entertainment. This study explores how this change in media content relates to partisan divides in satisfaction with democracy. Using data from a representative survey of 201,144 individuals, we linked respondents’ perceptions of democratic performance to their daily media exposure. We did so by analysing 1.5 million tweets from British newspapers using a topic modelling algorithm to identify shifts in topic salience and sentiment using sentiment analysis. Our findings reveal a decline in partisan media exposure during the pandemic, associated with increased satisfaction with democracy at both individual and collective levels, and a narrowing of cross-party divides. These results contribute to discussions on affective polarization, the winner-loser gap in democratic evaluation, and media framing effects, highlighting the potential influence of depoliticized news coverage on democratic attitudes.

This work aimed to evaluate the impact of conversion from native vegetation to pastures and agriculture on soil quality in the Brazilian semi-arid region and identify which soil attributes have the greatest potential as soil quality indicators. We collected soil samples at 0–10 and 10–20 cm layers from seven municipalities in the Brazilian semi-arid region. We determined the stocks of total soil organic carbon (TOC), total nitrogen (TN), carbon and nitrogen from microbial biomass (MB-C, MB-N), oxidizable fractions, humic substances, granulometry, soil bulk density (BD), pH, P, and cation exchange capacity (CEC). The evaluated systems were pasture, agriculture with different implementation times, and native forest (Caatinga biome). The results show that conventional cultivation and grazing systems lead to substantial losses of fundamental attributes needed to maintain soil quality. The study observed losses of MB-C, TOC, TN, and more recalcitrant fractions like fulvic acid and humin, along with a reduction in soil P and CEC. Soil physical, chemical, and biological attributes work as indicators of separation between environments; however, labile compartments showed greater potential as indicators of land use changes, being considered the main indicators in the soil quality assessment.

Every May 18, mourners gather near the sandy beaches of Mullivaikkal, a small strip between Chundikulam and Mulltaitivu in the Northern province of Sri Lanka, to commemorate the 2009 genocide against the Tamils. Mullivaikkal is where approximately three hundred thousand Tamil civilians found refuge as they fled the military bombardment between January and May 2009.1 Starting in 2010, the remembrance day commemoration attracts thousands of locals, coming together near the beach to reflect and remember. Increasingly, the commemoration also attracts transitional justice experts, along with diplomats and international governmental organization workers. In my contribution, I reflect on the work of the local and diaspora Tamil transitional justice experts as they begin to gather evidence from the families of victims for the newly created 2024 Commission for Truth, Unity and Reconciliation. Drawing on Homer's The Odyssey and the story of the “lotus eaters,” I frame these experts as “truth eaters,” preoccupied with collecting victim narratives for the purpose of personal gratification. As they engage in the repeated collection of particular elements of the victims’ truth—elements predicated on the demands of the field of transitional justice—the truth eaters are oblivious to the root causes of the war. I explain how attention to root causes through a Third World Approaches to International Law (TWAIL) lens can avoid the effects of the dominant liberal modes of truth seeking reflected in the work of these truth eaters.

Despite being a party to the Refugee Convention since 1981, Japan has historically admitted very few asylum seekers. However, recently the country's total protection rate has increased, from 2.3% in 2020 to 52% in 2022. This article explores this seemingly dramatic shift in Japan's refugee policy, tying the increased rate of asylum admissions to the country's broader foreign policy in the face of recent geopolitical challenges in Myanmar, Afghanistan, and Ukraine, while outlining the diverging pathways of admission utilized in each case.

Science shows mounting global health risks associated with plastics life cycle pollution. Leveraging evidence and streamlining research to inform policy is critical to safeguarding people and planet. We conducted an electronic survey questionnaire, between 16th April and 16th August 2024, amongst United Nations government delegates developing the Global Plastics Treaty. We explored (1) perceptions and prioritisation of human health evidence, (2) preferred plastic pollution mitigation strategies, and (3) priorities for health research. Responses were collected in Qualtrics and analysed using summary statistics, the Fisher’s Exact Test, and thematically mapped to the Policy Cycle Framework. We received 27 survey responses, balanced by gender and career stage, including 23 countries and all World Bank country income classifications and regions, but greater representation from high-income and European countries. Human health was the highest-ranking concern related to plastics risks (Sum of rank scores (SRS) = 54). Most delegates expressed strong conviction in evidence of risks associated with plastics chemicals, polymers, products, microplastics and broader life cycle emissions. Reducing plastics production (SRS = 53) and eliminating chemicals, polymers and products of concern (SRS = 53) were prioritised, even amongst those affiliated with waste management departments or less convinced of health risks. We found the least regard for recycling as a strategy to protect health (SRS = 4–5) and eliminating open burning was the most prioritised downstream measure (SRS = 15). Generating quantitative, causal data on risks across plastics life cycles, identifying emerging health hazards, defining criteria, safe lists and substitutes for chemicals, polymers and products were government delegate priorities for research, alongside tools to track policy impacts on health and greater bilateral communication between scientists and delegations. Health risks of all forms of plastic pollution were a concern for most delegates responding to our survey. We identified key priorities for policy-driven research to strengthen the science-policy interface and support evidence-based plastics policy that protects human health.
