Pangolins are some of the most overexploited but least studied mammals. The giant pangolin Smutsia gigantea is the largest of the eight pangolin species, measuring up to 180 cm in length and weighing up to 40 kg. It is a nocturnal, solitary species that occurs at low densities and little is known regarding its biology and ecology. It is distributed widely across the rainforests and forest savannah mosaics of equatorial Africa but its exact range extent is unknown. Apart from a single record in Kenya predating 1971, the eastern limit of its range was thought only to extend to central Uganda and western Tanzania. Here we present three spatially separate records confirming the presence of this species in Kenyan Afromontane forests. The three records are c. 120 km apart and c. 500 km east of the nearest confirmed giant pangolin population in Uganda. These records represent a significant range extension for the species and highlight the biodiversity and conservation importance of the Afromontane forests of western Kenya.

Decorated cists have been identified at three burial cairns in Kilmartin Glen, Mid Argyll. The paper provides a new analysis of the cover slab at Nether Largie North, which features a series of pecked axeheads. Previous studies suggested that they replaced an array of cup marks, but the evidence of photogrammetry suggests a longer sequence and a more complex scheme. The same approach was taken to the decorated cists beneath the Nether Largie Mid cairn and a comparable structure at Ri Cruin. Additional depictions were identified. The carvings within all three cists are organised in similar ways. They date from a period in the Early Bronze Age when metal was imported from Ireland. At the same time, the reuse of older structures suggests a new concern with the past.

Many policy decisions take input from collections of scientific models. Such decisions face significant and often poorly understood uncertainty. We rework the so-called confidence approach to tackle decision-making under severe uncertainty with multiple models, and we illustrate the approach with a case study: insurance pricing using hurricane models. The confidence approach has important consequences for this case and offers a powerful framework for a wide class of problems. We end by discussing different ways in which model ensembles can feed information into the approach, appropriate to different collections of models.

Recent research has established that south Scandinavia during the Nordic Bronze Age was entirely dependent on imported metal. It was obviously in contact with other parts of Europe and must have participated in a system of long-distance exchange. It is not clear how it would have operated, but it helps to explain the importance of watercraft and drawings of distinctive artefacts in the rock art on the Baltic and Atlantic coasts. A different group of images can be associated with inland areas where the art has a more restricted lexicon. Can the borderland between these traditions shed any light on the relationship between the seashore and the interior, and might this help to identify places where artefacts changed hands? This paper presents the results of fieldwork between Lakes Vänern and Vättern in Västra Götaland county, southern Sweden. It considers the character of inland rock art and whether some locations with more complex panels were used as ‘aggregation sites’.

OBJECTIVES/GOALS: Face transplant can offer functional and aesthetic restoration to patients who have exhausted reconstructive options. Ethical issues in face transplant still abound, including that of patient selection. The goal of this study was to assess ethicists’ viewpoints on face transplant. METHODS/STUDY POPULATION: A large-scale online survey of attendees of the International Conference on Clinical Ethics Consultation (N = 401) was performed to assess ethicists’ opinions on issues in face transplant. Questions were asked regarding the risk-benefit ratio of immunosuppression, permissibility of face transplant for more recipient subpopulations (including children and blind patients), donor-recipient age, gender, and ethnicity mismatches, and ethics committee make-up. RESULTS/ANTICIPATED RESULTS: Among 84 respondents, 84% agreed it is permissible to perform a face transplant on an adult with no medical contraindications. The majority of respondents agreed that it is permissible to perform a face transplant on a child or blind recipient. An issue of continued concern was risk of immunosuppression. Respondents had a high threshold of permissibility for ethnic mismatches between donor and recipient, and 43% reported it is permissible to have a gender mismatch. A 10 year age difference between donor and recipient was the most commonly accepted. Questions regarding the ideal composition of a face transplant ethics committee demonstrated consensus on the roles that should be represented. DISCUSSION/SIGNIFICANCE OF IMPACT: This study provides insight into ethicists’ viewpoints on face transplant, which demonstrates a high level of permissibility towards the procedure. This may be due to the early success of face transplants and the shifting ethical issues in the field to practical aspects of the procedure. This research also provides guidance to programs regarding questions of donor and recipient selection, ethics committee composition, and offers insight into strengthening the ethical framework of the field.

Analysis of radiocarbon dates has established the chronological contexts of three kinds of Neolithic monument in Britain: long mounds or long cairns, causewayed enclosures, and cursuses. It is more difficult to appreciate how such structures developed over time. The building of a barrow or cairn was sometimes the final act in a place that had already experienced a longer history. The construction of the monument brought activities to an end, and the site was effectively closed. Individual sequences were shorter than once thought but might be repeated at different locations over several hundred years.

On the other hand, the construction of causewayed enclosures according to a widely accepted template occurred almost simultaneously. Once those earthworks were established some went out of use, but a few others were adapted and changed so that they could play an increasing variety of roles over a longer period. The same contrasts are illustrated by cursuses. Timber structures in the north had finite histories before they decayed or were destroyed by fire, whilst earthworks had a wider distribution and enjoyed a longer currency. A similar approach might shed light on later monuments, including henges, stone circles, and round barrows. It is important to consider how the chronologies of all these structures are related to past conceptions of time.

The rock art of southern Scandinavia is characterized by depictions of watercraft. The majority are close to the coast, and they have been the primary focus of research. Less attention has been paid to similar representations associated with two large inland lakes in southern Sweden. In this article we present the results of fieldwork around Lake Vänern and Lake Vättern and consider the relationship of this rock art to the better-known images on the coast. We explore the practicalities of navigating between the sea and the interior and suggest that there was an important contrast between an early eastern sphere extending to Lake Vättern from the Baltic and a later western sphere connecting Lake Vänern with the Atlantic.

New radiocarbon (14C) dates suggest a simultaneous appearance of two technologically and geographically distinct axe production practices in Neolithic Britain; igneous open-air quarries in Great Langdale, Cumbria, and from flint mines in southern England at ~4000–3700 cal BC. In light of the recent evidence that farming was introduced at this time by large-scale immigration from northwest Europe, and that expansion within Britain was extremely rapid, we argue that this synchronicity supports this speed of colonization and reflects a knowledge of complex extraction processes and associated exchange networks already possessed by the immigrant groups; long-range connections developed as colonization rapidly expanded. Although we can model the start of these new extraction activities, it remains difficult to estimate how long significant production activity lasted at these key sites given the nature of the record from which samples could be obtained.

Within sight of the Neolithic axe quarries on the Langdale Pikes is a group of massive boulders at Copt Howe. The two largest command a direct view of the stone source where the sun sets into the mountainside at the midsummer solstice. Both are decorated by pecked motifs which resemble features of Irish passage tomb art. Small-scale excavation in 2018 showed that a rubble platform had been built at the foot of the main decorated surface and sealed two further motifs of similar character. New work has established an important sequence in Great Langdale. Recently obtained radiocarbon dates indicate that the main period of axe production was between 3800 and 3300 bc, whilst Irish megalithic art is later and was made between about 3300 and 2900 bc, suggesting that Copt Howe achieved its importance after axe-making had ceased or was in decline. That is consistent with an increasing emphasis on relations between northern Britain and Ireland during the Late Neolithic period. Perhaps Copt Howe itself was treated as a ‘natural’ passage tomb.
