Alpine tundra areas are threatened by anthropogenic climate change. They are also often represented as hotspots of endemism. Studying the insect communities associated with these habitats is therefore highly relevant. Melanoplus gaspesiensis Vickery is a grasshopper species known for its extremely limited distribution; it is considered endemic to Mont Albert, on the Gaspé Peninsula, Québec, Canada. Given its extremely limited distribution and with its habitat being particularly sensitive to climate change, the species is likely to soon be considered “at risk” at both the provincial and national levels. In order to confirm the current distribution of M. gaspesiensis, we sampled Acrididae on four alpine summits of the Gaspé Peninsula. Four species of Acrididae were captured. Almost 85% of the captured specimens were M. gaspesiensis, all of which were captured on Mont Albert. Our data are thus coherent with the species being endemic to that summit. The unique geology of Mont Albert (serpentine) may explain why M. gaspesiensis appears to be restricted to this one summit.

During the Nigerian Civil War, France became the main supplier of military assistance to the secessionist Biafra. In a neo-imperial pursuit to weaken the potential regional hegemon Nigeria, it secretly provided arms and ammunition to the Biafrans in collusion with Côte d'Ivoire and Gabon. Yet the driving force behind this Franco-African arms triangle was not the Elysée, but the Ivorian president Félix Houphouët-Boigny. Newly unearthed documentary evidence from French archives enables this article to break new historiographical ground: firstly, to show the Elysée's sheer reluctance to militarily assist Biafra and lack of a coherent policy in doing so; secondly, to confirm Houphouët-Boigny as the “mastermind” behind the arming of Biafra, as well as to identify his Cold War motivations; thirdly, to uncover Gabonese president Omar Bongo's increasing agency and influence in the scheme; fourthly, to demonstrate that it was the Ivorian and Gabonese presidents who transformed the arms triangle into a square by bringing the Rhodesians and, especially, the South Africans in; and, finally, to retrace the emergence and functioning of the “African-French” military assistance to Biafra at the policy level not only from Paris's, but also Abidjan's and Libreville's perspectives.

This response to the comments on The Digital Factory discusses why and how the concepts of the digital factory and digital Taylorism have been applied in the book, as well as the question of the relationship between digital control and workers' resistance to algorithmic management technologies. While agreeing with the comments that point to the limitations of the concepts used, this response argues that these can be productive precisely by drawing our attention to aspects that are otherwise difficult to bring to light. In terms of the potential for workers' resistance, many collective and individual forms of such resistance remain possible in labour regimes under algorithmic management, as well as in other coexisting labour regimes.

Theories about the impact of digital technology on society and the development of capitalism and debates about the influence of digital information technologies on the future of work have been abundant since the end of the twentieth century. Most of the academic debate has taken place outside labour history, leaving the actual effects of digital technologies on human work and labour relations often overlooked. Moritz Altenried's The Digital Factory: The Human Labor of Automation focuses precisely on these effects, and as such provides a good opportunity to engage with these debates from a labour history perspective. This Review Dossier includes four comments on Altenried's book, by Bridget Kenny, Nico Pizzolato, Görkem Akgöz, and Greg Downey, to which the author responds. The contributors focus on different aspects of The Digital Factory depending on their own perspective on recent developments in the digital economy in the larger context of global capitalism.

This article describes John Wesley's evolving visions of Christian singleness (celibacy) and three commitments related to his changing views: a commitment to celibacy in an Oxford college; a commitment to marriage with Mary Vazeille; a de facto commitment to single life after Mary's separation from him. Protestant Churches lacked structures to support celibate commitment, structures that might have discouraged his unguarded and intimate correspondence with married women that lay behind his separation from Mary. The article asks why Protestants, although formally allowing single life, have not found ways to honour commitments to it.

While recent genomic and isotopic information show that migration has been pervasive along human history, southern Andean archaeology has largely overlooked its importance in shaping human trajectories of sociocultural change. Building on previous isotopic research that identified the presence of migrant farmers in the Uspallata Valley (Mendoza, Argentina), we present chronological and bioarchaeological results that help to characterize the timing and mode of human migrations in the southern Andes. The burials with migrants show the representation of the different age classes, including a high abundance of children, as well as both men and women, suggesting that family groups were likely involved. The Bayesian modeling of 16 direct dates for migrants indicates that these migrations started between 1210–1275 CE (median 1255 CE) and finished at 1320–1425 CE (median 1360 CE), indicating that there is nearly no overlap between the commencement of this migration phase and the southwards expansion of the Inka Empire. The model defines a diachronic process that lasted between 55 and 195 years, implying that migration to Uspallata was a multi-generational process that involved between two and eight generations (median of four generations). Our contextual, bioarchaeological and chronological evidence indicates that the conditions fostering migration to Uspallata were sustained through time, inviting to explore persisting push-pull dynamics acting during this period. 87Sr/86Sr results show that migration occurred across the daily territories of these groups and may have involved movement across social or ethnic frontiers.

Between 1969 and 1975 the excavations promoted by the Soprintendenza alle Antichità dell'Etruria Meridionale in the area to the east of the church of Santa Maria of Falleri identified a building in opus quadratum, located at the intersection between the main east–west and north–south urban road axes. As part of the Falerii Novi Project, this area has been systematically surveyed and (re)studied, applying an interdisciplinary approach. This has allowed the identification in this area of a monumental republican temple, linked to the forum, which should be placed in the context of the earliest development of the town, which has been known to us up to now only via literary sources. The identification of the republican temple of Falerii Novi contributes to fresh insights into the foundation of the town and its urban development.

The aim was to explore whether the time-lapse imaging system can help day-3 single cleavage embryo transfer to obtain comparative clinical outcomes to day-4 or 5. The data of 1237 patients who underwent single embryo transfer from January 1, 2018, to September 30, 2020, in our reproductive medicine centre were retrospectively analysed. They were divided into the day-3 single cleavage-stage embryo transfer (SCT) group (n = 357), day-4 single morula transfer (SMT) group (n = 129) and day-5 single blastocyst transfer (SBT) group (n = 751) according to the different embryo transfer stage. The clinical and perinatal outcomes of the three groups were analysed and compared. The clinical pregnancy rates of the patients in the day-3 SCT group, day-4 SMT group and day-5 SBT group were 68.07, 70.54 and 72.04%, respectively. The live birth rates were 56.86, 61.24 and 60.99%, respectively. The monozygotic twin (MZT) rate in the day-3 SCT group was significantly lower than that in the day-5 SBT group (P = 0.049). Regarding perinatal outcomes, only the secondary sex ratio had a significant difference (P < 0.05). After age stratification, no improvement was found in the pregnancy outcomes of patients >35 years of age receiving blastocyst transfer. Our findings suggest that for patients with multiple high-quality embryos on day-3, prolonging the culture time can improve the pregnancy outcome to some extent, but it will bring risks. For centres that have established morphodynamic models, day-3 SCT can also achieve an ideal pregnancy outcome and reduce the rate of monozygotic twins and sex ratio.
