In April 2023, eighteen scholars from nine different subjects representing the humanities, natural and social sciences came together for a one-day workshop at St John’s College, Durham. Despite our differences, all had one aim: the study of past environmental change and its effects on human societies. Talking across disciplinary divides, we discussed what environmental history is, how it may or may not contribute to tackling the climate crisis, and the problems of sources, scale and temporality. This article collects select conversations into a roundtable format split into four areas: scale, time and space, interdisciplinarity, and the future of environmental history. We argue that environmental history is more usefully understood not as a distinct sub-field of history, but as an interdisciplinary meeting place for innovative collaboration. This also presents a model for future research aimed at tackling the climate crisis at higher education institutions.

Despite an early surge in copper-ore mining during the sixth and fifth millennia BC (the ‘boom’), evidence for metal production in the Balkans dwindles in the fourth millennium (the ‘bust’). Here, the authors present new evidence for copper mining at Curak in south-west Serbia, c. 3800 cal BC, during this apparent downturn. By integrating field surveys, excavations and provenance analyses, they explore activity at the site, challenging the visibility bias in the archaeological record of this region for this key period. Rather than a societal collapse, the authors argue, fewer artefacts may instead reflect a widening Balkan sphere of influence.

Aims: ECT is a well-evidenced, cost-effective intervention for treatment-resistant depression. In Ireland acute (twice-weekly) outpatient ECT for depression has not been reported, though common elsewhere. Ireland has among the lowest number of inpatient psychiatry beds per person in Europe. We observed a clinical need for acute outpatient ECT for people who could not access elective inpatient care.

Methods: All cases provided written informed consent. A multidisciplinary (psychiatry, anaesthesiology, nursing) protocol for assessment and delivery of acute outpatient ECT was developed and implemented, cases described and feedback from stakeholders sought in an acceptability forum.

Results: Four medically stable patients (ASA Grades 2) completed acute outpatient ECT, receiving between n=6 and n=14 ECT treatments, attending from home. N=140 inpatient psychiatry bed days were saved, and n=45 community psychiatry reviews were required. No adverse events or medical interventions occurred. Three people had CGI outcome of “very much improved” and one person halted their treatment course when “minimally improved”, citing lack of response. Stakeholder feedback in an acceptability forum highlighted the increased resource intensity of twice weekly community review for outpatient ECT, and the positive outcomes for treatment-resistant depression.

Conclusion: Acute outpatient ECT was safe and effective in this case series and resulted in n=140 psychiatry inpatient bed days being saved. There was an increased need for reviews from the community team during the treatment protocol. Medically stable patients with substantial social support were eligible for this pilot phase, thus a priority for future development must be equity of access to this effective intervention.

Distinguishing early domesticates from their wild progenitors presents a significant obstacle for understanding human-mediated effects in the past. The origin of dogs is particularly controversial because potential early dog remains often lack corroborating evidence that can provide secure links between proposed dog remains and human activity. The Tumat Puppies, two permafrost-preserved Late Pleistocene canids, have been hypothesized to have been littermates and early domesticates due to a physical association with putatively butchered mammoth bones. Through a combination of osteometry, stable isotope analysis, plant macrofossil analysis, and genomic and metagenomic analyses, this study exploits the unique properties of the naturally mummified Tumat Puppies to examine their familial relationship and to determine whether dietary information links them to human activities. The multifaceted analysis reveals that the 14,965–14,046 cal yr BP Tumat Puppies were littermates who inhabited a dry and relatively mild environment with heterogeneous vegetation and consumed a diverse diet, including woolly rhinoceros in their final days. However, because there is no evidence of mammoth consumption, these data do not establish a link between the canids and ancient humans.

Recent changes to US research funding are having far-reaching consequences that imperil the integrity of science and the provision of care to vulnerable populations. Resisting these changes, the BJPsych Portfolio reaffirms its commitment to publishing mental science and advancing psychiatric knowledge that improves the mental health of one and all.

An important component of post-release monitoring of biological control of invasive plants is the tracking of species interactions. During post-release monitoring following the initial releases of the weevil Ceutorhynchus scrobicollis Nerenscheimer and Wagner (Coleoptera: Curculionidae) on garlic mustard, Alliaria petiolata (Marschall von Bieberstein) Cavara and Grande (Brassicaceae), in Ontario, Canada, we identified the presence of larvae of the tumbling flower beetle, Mordellina ancilla Leconte (Coleoptera: Mordellidae), in garlic mustard stems. This study documents the life history of M. ancilla on garlic mustard to assess for potential interactions between M. ancilla and C. scrobicollis as a biological control agent. Garlic mustard stems were sampled at eight sites across southern Ontario and throughout the course of one year to record the prevalence of this association and to observe its life cycle on the plant. We found M. ancilla to be a widespread stem-borer of late second–year and dead garlic mustard plants across sampling locations. This is the first host record for M. ancilla on garlic mustard. The observed life cycle of M. ancilla indicates that it is unlikely to negatively impact the growth and reproduction of garlic mustard and that it is unlikely to affect the use of C. scrobicollis as a biological control agent.
