The Namibian Swakara industry, a type of sheep farming focused on the production of lamb pelts for the fashion industry, currently faces a crisis situation. Formerly one of the most important export products from Namibia, a combination of drought, falling pelt prices and the effects of the COVID-19 pandemic now threaten the survival of Swakara, the Namibian Karakul. The current crisis is articulated in extinction narratives. The potential end of Swakara farming as a way of life and a set of knowledge practices is narratively interwoven with the potential disappearance of Swakara from the Namibian landscape. Extinction narratives in the context of Swakara farming in Namibia blur the lines of human and nonhuman ways of life and their disappearance.

This article discusses Estonian author Andrus Kivirähk’s novel The Man Who Spoke Snakish in the context of language extinction and biocultural diversity. The novel is set in Medieval Estonia, but the viewpoint of the protagonist as a speaker of a vanishing language from a vanishing culture resonates with the lived experience of millions of people who have lost lifeways and livelihoods to colonisation and cultural assimilation. The fictitious language of Snakish allows its speakers to integrate fully into the natural world and to form complex interdependent relationships with non-human animals. This web of nature, culture and language is destroyed by a colonising society that is anthropocentric, ecologically destructive and socially hierarchical, and which views nature as something to exploit or fear. The novel explores the emotions of grief and loss for both a culture and an ecosystem heading for extinction.

Among the stories on individual examples of charismatic fauna, there are also extinction stories that evoke databases and their aesthetics in how they list endangered species. At the same time, these different stories grapple with a legacy of taxonomy that, while necessary in conservation, also carries a history of exclusion. This paper turns to the poetry of Claire Wahmanholm and Juliana Spahr to consider some of the ways extinction stories can be told outside of the relatively narrow scope of charismatic species. To begin, I reflect on extinction storytelling and the classificatory impulse in some of these stories, including poetry. Then, I consider scientific practices of naming before I turn back to Wahmanholm and Spahr and explore practices of naming and classification in their poetry. Following that, I dwell on the influence of scientific classification on the ways people including poets can engage with extinction. The poems in this paper are not merely an object for analysis; they should be considered an invitation to come to terms with and move beyond complicated histories and practices of naming and classification in storytelling.

Phylodynamic models can be used to estimate diversification trajectories from time-calibrated phylogenies. Here we apply two such models to phylogenies of non-avian dinosaurs, a clade whose evolutionary history has been widely debated. Although some authors have suggested that the clade experienced a decline in diversity, potentially starting millions of years before the end-Cretaceous mass extinction, others have suggested that the group remained highly diverse right up until the Cretaceous-Paleogene (K-Pg) boundary. Our results show that model assumptions, likely with respect to incomplete sampling, have a large impact on whether dinosaurs appear to have experienced a long-term decline or not. The results are also highly sensitive to the topology and branch lengths of the phylogeny used. Developing comprehensive models of sampling bias, and building larger and more accurate phylogenies, are likely to be necessary steps for us to determine whether dinosaur diversity was or was not in decline before the end-Cretaceous mass extinction.

Patterns of extinction risk can vary across taxa, with species of some groups being particularly vulnerable to extinction. Rails (Aves: Rallidae) represent one of the most extreme yet well-documented cases of mass extinction within a modern vertebrate group. Between 54 and 92% of rail species became extinct following waves of human contact during both the Holocene and the Anthropocene eras, and a third of the extant species are currently threatened or near-threatened. Here, we (1) examine extinction filters through consecutive human contacts with rails, investigating the role of intrinsic life-history traits and (2) investigate the drivers of contemporary vulnerability. During the most recent wave of extinction, we found that body size was an important correlate of rail extinctions, with both smaller and larger bodied species more likely to become extinct. Island endemism and small clutch size were the strongest predictors of contemporary vulnerability. Overall, island endemic rails tend to follow the same trajectory as extinct species, suffering mostly from invasive predators and overhunting, but with different traits targeted contemporarily compared to past extinctions. Moreover, modern anthropogenic threats have created the potential for new intricate pathways – or a contemporary ‘field of bullets’ – making future vulnerability potentially less predictable.

The Permian–Triassic climate crisis can provide key insights into the potential impact of horizon threats to modern-day biodiversity. This crisis coincides with the same extensive environmental changes that threaten modern marine ecosystems (i.e., thermal stress, deoxygenation and ocean acidification), but the primary drivers of extinction are currently unknown. To understand which factors caused extinctions, we conducted a data analysis to quantify the relationship (anomalies, state-shifts and trends) between geochemical proxies and the fossil record at the most intensively studied locality for this event, the Meishan section, China. We found that δ18Oapatite (paleotemperature proxy) and δ114/110Cd (primary productivity proxy) best explain changes in species diversity and species composition in Meishan’s paleoequatorial setting. These findings suggest that the physiological stresses induced by ocean warming and nutrient availability played a predominant role in driving equatorial marine extinctions during the Permian–Triassic event. This research enhances our understanding of the interplay between environmental changes and extinction dynamics during a past climate crisis, presenting an outlook for extinction threats in the worst-case “Shared Socioeconomic Pathways (SSP5–8.5)” scenario.

In its nearly 80-year history, the International Whaling Commission (IWC) has shifted from a “whalers club” to an international governance body chiefly focused on the protection and conservation of global cetacean populations. Drawing on recent scholarship on extinction and its entanglements, this article compares two addresses given by whalers at IWC meetings 40 years apart to problematise the way whaling and its relation to extinction is conceptualised in international environmental governance. Guided by practice-oriented document analysis and recent theorisation of extinction as an entangled process, this article analyses the personal stakeholder testimonies from two different representatives of the North Slope whalers of Northern Alaska to the IWC – one in relation to the 1977 Alaska bowhead whaling controversy and the other in the context of the 2018 negotiations over streamlining Aboriginal Subsistence Whaling management and supporting greater flexibility and Indigenous autonomy. By comparing these two statements from very different points of history for the IWC and the governance of Indigenous whaling, this article illustrates some of the ongoing struggles for environmental governance to recognise extinction as a complex, multifaceted process that reverberates throughout human and more-than-human communities.

The Scottish Small Isles – comprising Muck, Rùm, Eigg, Canna, and by extension, Coll – are geologically complex, with intersecting rock samples from the Archean (Lewisian Gneiss basements formed approximately 3 billion years ago), Proterozoic (Torridonian sandstone formed approximately 1 billion years ago), Mesozoic (sedimentation deposited approximately 200 million years ago) and Palaeocene (basalt formed approximately 55.8 million years ago as part of the Palaeocene–Eocene Thermal Maximum event). This practice research article – drawing on palaeontology, kinaesthetic learning and creative writing – takes the Small Isles as a case study for what geologist Marcia Bjornerud defines as a discernible “timefulness” that humans should seek to attain: “an acute consciousness of how the world is made by–indeed, made of–time” (2020, Timefulness: How Thinking Like a Geologist Can Help Save the World, 5). Through their lithic intrusions, and interruptive strata, the Small Isles offer an alternative form of pedagogy: where multiple epochs, tenses and tempos visibly converse with one another; where “polytemporality” can be witnessed and physically experienced; where the notion of linear time is destabilised.

Traces of early hominin cultural dynamics are revealed through the spatial and temporal character of the archaeological record. In the European Lower Palaeolithic, biface occurrences provide insights into episodes of cultural loss, persistence and convergence during the Acheulean, the longest known prehistoric cultural phenomenon. Here, the cohesiveness of Europe’s Acheulean record is statistically assessed under multiple spatial scenarios. Repeated cycles of cultural loss are identified in northern Europe, while southern Europe is demonstrated to have a continuous record of Acheulean presence. These data support longstanding hypotheses concerning an absence of Acheulean populations in northern Europe during glacial periods – a result that should increasingly be applied with caution. In southern Europe, Iberia displays the loss of Acheulean cultural information between c. 850 and 500 thousand years ago, with the Italian peninsula potentially acting as a source population for its later reintroduction. When investigated at a continental-level there are no clear episodes of cultural loss. Current evidence therefore suggests that once Acheulean cultural information was introduced to Europe, it never wholly left.

Different stakeholders and actors frequently describe environmental challenges as ‘crises’. These crises are often wicked problems that are difficult to resolve due to the complex and contradictory nature of the evidence and knowledge systems surrounding them. Here, we examine a crisis narrative surrounding the IUCN-declared Asian Songbird Crisis (ASC), with its epicentre in Indonesia, where an extensive birdkeeping culture persists. We investigate how bird extinction is perceived by different actors, particularly conservation law enforcement and practitioners working in this space. We unravel local perspectives on the complex relationship between bird trade and extinction through one-to-one interviews and focus groups. Our examination reveals a diversity of attitudes to the ASC, with many law enforcement actors not recognising the crisis label. Market mechanisms result in complex shifts in harvesting pressure onto one or more closely related similar species. The findings challenge the prevailing notion that species extinction significantly affects wildlife trades, emphasising the plastic nature of trade and the coming and going of species fashions. By revealing the divergent views of actors on extinction and the ASC, we highlight the need for shared language, particularly the implications of the ‘crisis’ label, around species extinction.

In 2021, scientists published a preprint stating that the dugong population of Okinawa had declined below the minimum viable population and should be considered extinct. The publication led to an outcry amongst Japanese/Okinawan environmentalists and to criticism by international dugong specialists. Two issues were raised: 1) Declaring dugongs extinct, although feeding trails were found in several locations, misrepresented the reality in Okinawan waters, and could have negative impacts on conservation measures; 2) Three authors were sitting on the Environmental Monitoring Committee for a controversial military base construction project in an area where dugongs were frequently spotted before construction commenced. The presence/absence of dugongs at the site had become a political issue, as the animal’s protected status and its depiction in folklore gave it symbolic meaning in the anti-base movement. The declaration of dugong extinction reminded protesters of a former Environmental Impact Assessment conducted by Japan’s Ministry of Defence, declaring the site to be no relevant dugong habitat. The paper explores the implications of the preprint for the political situation in Okinawa and questions the certainty of dugong extirpation in the region. It argues that speculations about extinction cannot be divorced from the political contexts to which they are invariably tied.
