Three late medieval inventories of the chapel surrounding the shrine of St Edward the Confessor at Westminster Abbey, London, record the presence of a number of books and pamphlets among the relics and liturgical paraphernalia. This article discusses these books, their significance and the reason for their maintenance at the shrine, and offers possible identifications with several surviving manuscripts.

Many marine fish species are experiencing population declines, but their extinction risk profiles are largely understudied in comparison to their terrestrial vertebrate counterparts. Selective extinction of marine fish species may result in rapid alteration of the structure and function of ocean ecosystems. In this study, we compiled an ecological trait dataset for 8,185 species of marine ray-finned fishes (class Actinopterygii) from FishBase and used phylogenetic generalized linear models to examine which ecological traits are associated with increased extinction risk, based on the International Union for the Conservation of Nature Red List. We also assessed which threat types may be driving these species toward greater extinction risk and whether threatened species face a greater average number of threat types than non-threatened species. We found that larger body size and/or fishes with life histories involving movement between marine, brackish, and freshwater environments are associated with elevated extinction risk. Commercial harvesting threatens the greatest number of species, followed by pollution, development, and then climate change. We also found that threatened species, on average, face a significantly greater number of threat types than non-threatened species. These results can be used by resource managers to help address the heightened extinction risk patterns we found.

This article argues that the encounter between Andromache and Ulysses in Seneca's Troades engages with the genre of declamation to juxtapose two different discourses surrounding torture: one focussed on torture's connection to truth, the other on its connection to tyranny. It describes how the Greek general Ulysses, convinced of the danger of letting the Trojan prince Astyanax live, threatens his mother Andromache with physical torture in order to ascertain the truth of Astyanax's whereabouts. However, Ulysses is countered by Andromache's rhetoric, through which, the article shows, she depicts herself as the archetypal heroic victim of a tyrant. It discusses how Ulysses innovates with an effective psychological torture in response. The article sets the scenario within the broader rhetorical context and demonstrates how it reflects debate among the contemporary elite about the necessity of, and the risks from, the rising use of torture by the Julio-Claudian emperors, a debate which resonates in the modern era.

This paper draws upon documentary, visual and archaeological evidence to chart the development of the sacristy of Westminster Abbey from its construction as one of the earliest parts of the abbey’s thirteenth-century rebuilding to its demolition in the mid-eighteenth century − a story that reflects wider changes of religious and political history.

The typical marine animal has increased in biovolume by more than two orders of magnitude since the beginning of the Cambrian, but the causes of this trend remain unknown. We test the hypothesis that the efficiency of intra-organism oxygen delivery is a major constraint on body-size evolution in marine animals. To test this hypothesis, we compiled a dataset comprising 13,723 marine animal genera spanning the Phanerozoic. We coded each genus according to its respiratory medium, circulatory anatomy, and feeding mode. In extant genera, we find that respiratory medium and circulatory anatomy explain more of the difference in size than feeding modes. Likewise, we find that most of the Phanerozoic increase in mean biovolume is accounted for by size increase in taxa that accomplish oxygen delivery through closed circulatory systems. During the Cambrian, water-breathing animals with closed circulatory systems were smaller, on average, than contemporaries with open circulatory systems. However, genera with closed circulatory systems superseded in size genera with open circulatory systems by the Middle Ordovician, as part of their Phanerozoic-long trend of increasing size. In a regression analysis, respiratory and circulatory anatomy explain far more size variation in the living fauna than do feeding modes, even after accounting for taxonomic affinity at the class level. These findings suggest that ecological and environmental drivers of the Phanerozoic increase in the mean size of marine animals operated within strong, anatomically determined constraints.

This study used a single case experimental design to investigate the use of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP) among a sample of individuals with depression and anxiety who also presented with borderline personality disorder (BPD). Eight women received individual treatment with the UP over the course of 14–16 treatment sessions, and were assessed for anxiety and depression severity on a weekly basis over a 2–6 week baseline period and throughout treatment. Three of the eight participants demonstrated reliable pre- to post-treatment clinical improvements on depression and stress scales, and one participant demonstrated a reliable reduction on an anxiety scale. Two participants demonstrated a reliable improvement in overall anxiety. The results indicate that the UP applied to individuals diagnosed with primary BPD may lead to clinical improvement in depression, stress and anxiety for some individuals. However, the majority of individuals with BPD in our sample did not show strong improvement, and this suggests the need for additional sessions of UP or an intervention that focuses on the symptoms of BPD specifically for some women.

In an earlier paper that looked at the dating of Edward the Confessor’s shrine at Westminster Abbey and which was published in volume 97 of The Antiquaries Journal, the authors suggested that a scribal error in the recording of the original inscription by the fifteenth-century monk Richard Sporley may have led to the incorrect date of 1279 being given for the construction (or, at least, completion) of the shrine. As a result of the debate aroused by that earlier paper, the authors have now reconsidered and slightly amended their original argument.

The quantity of biomass in an ecosystem is constrained by energy availability. It is less clear, however, how energy availability constrains taxonomic and functional diversity. Competing models suggest biodiversity is either resource-limited or far from any bound. We test the hypothesis that functional diversity in marine bivalve communities is constrained by energy availability, measured as particulate organic carbon (POC) flux, in the modern oceans. We find that POC flux predicts the relative prevalence of ecological modes in both the Atlantic and Pacific Oceans. Moreover, the associations of ecological modes with POC fluxes are similar between the Atlantic and Pacific despite being based on independent sets of species, indicating a direct causal relationship. We then use the relationship between POC flux and the prevalence of functional groups in the modern to test the hypothesis that the trend of increasing functional diversity in bivalves across the past 500 Myr has occurred in response to increased POC flux. We find no evidence that the earliest-appearing modes of life are preferentially associated with low-POC environments or that the mean POC flux experienced by marine bivalves has increased across geological time. To reconcile the close association between ecological mode and POC flux in the modern oceans with the lack of evidence for increasing POC fluxes across time, we propose that POC flux has not increased substantially over time but, rather, the increase in bivalve functional diversity enabled bivalves to become more abundant, to occupy a broader range of environments, and to capture a greater fraction of the total POC flux. The results here suggest at the geographic scale of oceans and through geologic time bivalve diversity was not bounded by food availability.

This paper re-evaluates the evidence for the dating of Edward the Confessor’s shrine at Westminster Abbey, which has been the subject of debate for many years. The paper presents a new argument that the manuscript evidence for a later date is based on an identifiable scribal error, locates the source of this error and postulates an alternative original reading of the inscription on the shrine pedestal.

The mortuary roll of John Islip (1464–1532), Abbot of Westminster, is the finest example of its kind to survive in England. The drawings, possibly by Gerard Horenbout, afford the only views of the interior of Westminster Abbey before the Dissolution. The discovery of eighteenth-century copies of an unknown, coloured version of the roll provides important new evidence for both the circumstances of the production and the later history of both rolls. It also provides, for the first time, an authentic colour view of the interior of Westminster Abbey in the late medieval period, and new information on its decoration.

The modern structure of marine benthic ecosystems was largely established during the Jurassic and Early Cretaceous (200–100 Ma), a transition that has been termed the Mesozoic Marine Revolution (MMR). Although it has been suggested that the MMR marks an increase in the average energy consumption of marine animal ecosystems, this hypothesis has not been evaluated quantitatively. In this study, we integrate body size and abundance data from the fossil record with physiological data from living representatives to estimate mean per capita metabolic rates of tropical to subtropical assemblages of shallow-marine gastropods—a major component of marine ecosystems throughout the Meso-Cenozoic—both before and after the MMR. We find that mean per capita metabolic rate rose by ∼150% between the Late Triassic and Late Cretaceous and remained relatively stable thereafter. The most important factor governing the increase in metabolic rate was an increase in mean body size. In principle, this size increase could result from secular changes in sampling and taphonomic biases, but these biases are suggested to yield decreases rather than increases in mean size. Considering that post-MMR gastropod diversity is dominated by predators, the net primary production required to supply the energetic needs of the average individual increased by substantially more than 150%. These data support the hypothesis that benthic energy budgets increased during the MMR, possibly in response to rising primary productivity.

The small size of Early Triassic marine organisms has important implications for the ecological and environmental pressures operating during and after the end-Permian mass extinction. However, this “Lilliput Effect” has only been documented quantitatively in a few invertebrate clades. Moreover, the discovery of Early Triassic gastropod specimens larger than any previously known has called the extent and duration of the Early Triassic size reduction into question. Here, we document and compare Permian-Triassic body size trends globally in eight marine clades (gastropods, bivalves, calcitic and phosphatic brachiopods, ammonoids, ostracods, conodonts, and foraminiferans). Our database contains maximum size measurements for 11,224 specimens and 2,743 species spanning the Late Permian through the Middle to Late Triassic. The Permian/Triassic boundary (PTB) shows more size reduction among species than any other interval. For most higher taxa, maximum and median size among species decreased dramatically from the latest Permian (Changhsingian) to the earliest Triassic (Induan), and then increased during Olenekian (late Early Triassic) and Anisian (early Middle Triassic) time. During the Induan, the only higher taxon much larger than its long-term mean size was the ammonoids; they increased significantly in median size across the PTB, a response perhaps related to their comparatively rapid diversity recovery after the end-Permian extinction. The loss of large species in multiple clades across the PTB resulted from both selective extinction of larger species and evolution of surviving lineages toward smaller sizes. The within-lineage component of size decrease suggests that only part of the size decrease can be related to the end-Permian kill mechanism; in addition, Early Triassic environmental conditions or ecological pressures must have continued to favor small body size as well. After the end-Permian extinction, size decrease occurred across ecologically and physiologically disparate clades, but this size reduction was limited to the first part of the Early Triassic (Induan). Nektonic habitat or physiological buffering capacity may explain the contrast of Early Triassic size increase and diversification in ammonoids versus size reduction and slow recovery in benthic clades.

The Permian–Triassic boundary, examined at two sections in the Southern Alps, occurs ~ 1.0 to 1.5 m above the base of the Tesero Oolite Member of the Werfen Formation in a depositionally continuous sequence of inner neritic carbonates. Lagenide foraminifers from the boundary interval comprise 27 species in 15 genera plus additional unidentified taxa, most of which became extinct during the end-Permian crisis. The only survivors were “Nodosaria” elabugae and unidentified species in Geinitzina and Nodosinelloides, with representatives of the latter two genera being short-term holdovers. The end-Permian lagenide extinction level occurs a few decimeters below the biostratigraphically defined erathem boundary, just above the contact between the Bulla Member of the Bellerophon Formation and the overlying Tesero Oolite Member. Confidence intervals (>96%) for the lagenide extinction at the two sections are 0.03 and 0.04 m thick. Plots of species' stratigraphic abundance versus their last observed occurrences below the estimated extinction intervals at both localities are consistent with abrupt extinction or gradual extinction lasting no more than the time required for 1 m of rock to accumulate. Blooms of the foraminiferal disaster taxa Rectocornuspira kalhori and Earlandia sp. occur in the extinction interval and continue well into the Dienerian part of the Mazzin Member of the Werfen Formation, consistent with a protracted survival phase. A detailed carbon isotope record has been obtained from rocks bracketing the extinction at the well-known Tesero section. The combined microfossil and carbon isotope data indicate that the extinction occurred during an initial negative shift in δ13C. Therefore, the negative excursion is likely to be related to the cause of extinction and unlikely to be merely a consequence of extinction.
