AbstractLarge numbers of gamebirds (pheasants Phasianus colchicus, red-legged partridges Alectoris rufa and mallard Anus platyrhynchos) are released annually in the UK to support recreational shooting. It is important to know how many of these birds are being released because their release and management has ecological effects on the wildlife and habitats of the UK. There is little regulation governing their release, and consequently, an accurate figure for the numbers being released is unknown. I took 12 different approaches, totalling 4329 estimates of the numbers of birds being released annually, based on a series of datasets that described numbers of birds being held for breeding, rearing or release, being released, managed or shot on game shoots, being shot by individual guns or being recorded during breeding bird surveys. These 12 approaches produced estimates ranging from 14.7 to 106.1 million with a mean of 43.2 million (95% CI 29.0–57.3 million). This suggests that 31.5 million pheasants (range 29.8–33.7 million), 9.1 million red-legged partridges (range 5.6–12.5 million) and 2.6 million mallard (range 0.9–6.0 million) are released annually in the UK. These figures differ substantially from both official records of gamebirds and previous published estimates, and I discuss why such differences may occur. I set these figures in the context of the number and behaviour of shoots operating in the UK. Improved estimates of numbers of gamebird being released are critical if we are to better understand the ecological effects occurring in areas where they are released and managed.

ABSTRACTLarge numbers of gamebirds (pheasants Phasianus colchicus, red-legged partridges Alectoris rufa and mallard Anus platyrhynchos) are released annually in the UK to support recreational shooting. It is important to know how many of these birds are being released because their release and management has ecological effects on the wildlife and habitats of the UK. There is little regulation governing their release and consequently the numbers being released are unknown. I made 71 estimates of the numbers released based on numbers being reported formally via import controls and the Poultry Register, or extrapolated based on the breeding outputs of reared birds, or extrapolated based on the likely numbers and behaviour of shoots, or extrapolated based on observations of surviving birds. Based on the set of these estimates that fall within credible boundaries (ranging from 14.3 to 70.1 million birds), I estimate a mean of 34.5 million birds (95%CI 30.9-38.1 million) and a median value of 32.1 million (IQR 22.0-44.9 million) being released. This suggests that 24.3-25.3 million pheasants, 4.2-9.4 million partridges and 1.0-4.9 million mallard are released annually in the UK. These figures are markedly lower than previous published estimates and I discuss why such differences may occur. I set these figures in the context of the number and behaviour of shoots operating in the UK.

AbstractMillions of individuals of two species of non-native galliform birds, the Common Pheasant (Phasianus colchicus) and Red-legged Partridge (Alectoris rufa) are released into the British countryside annually in late summer, supplementing established breeding populations of these two species. The biomass of birds involved in these releases has been compared to the British breeding bird biomass. However, the validity of this comparison is compromised because the biomass of wild birds varies across the year due to reproduction, mortality and migration. How the biomass of Common Pheasants and Red-legged Partridges compares to that of other British bird species in late summer, or across the whole year, is currently unknown. Here, we produce estimates of how British bird biomass varies across the year, to assess the contribution of the two non-native galliforms to this variation. We show that overall British bird biomass is probably lowest around the start of the breeding season in April, and peaks in late summer and autumn. We estimate that around a quarter of British bird biomass annually is contributed by Common Pheasants and Red-legged Partridges, and that at their peak in August these two species represent about half of all wild bird biomass in Britain.

Milestones are often seen as opportunities for reflection and reminiscence. As this edition of the journal coincides with the 10th anniversary of my consultant appointment I hope readers will forgive a couple of paragraphs of self-indulgence. The phrase: ‘Where did all that time go?’ will probably be familiar to physicians at a more advanced stage of their career. With medical students now returning as specialist registrars, and former house officers appearing as consultant colleagues, the passage of time is increasingly apparent. I recently realised that our current third year students were born in the year I clerked my first patient: surprisingly I still remember his name, age and diagnosis, unlike many of those (and all of the students!) who I have seen since. On a more positive note, there have clearly been a lot of changes over these ten years: at the time of my appointment in June 1999 there was just a small handful of ‘acute physicians’ in the UK. SAM meetings attracted barely 100 delegates, despite providing free admission, and most of us had planned our escape route in case the acute medicine concept went ‘belly-up’ before our retirement. Now, with several hundred acute medicine consultants, similar numbers of trainees, and ‘full speciality’ status rapidly approaching, job security should no longer be a major concern. Indeed, the last 12 months has seen a further considerable expansion of the speciality; all of the first cohort of acute medicine trainees in Wessex have secured consultant positions, and I am told that SAM now has close to 700 full members. What the next ten years will bring remains to be seen, but with an ageing population and year-round pressures from rising emergency admissions, acute medicine will surely continue to strengthen. As I indicated last time, an increasing number of research-based submissions will be trickling into the journal over the next few editions. The impact of alcohol on the Health Service is a subject which has been at the top of the political agenda in recent months. So it is timely to include an article highlighting its impact on the Acute Medical intake in a busy Teaching hospital in this edition of the journal. The finding that one-in-five patients admitted to the AMU were considered ‘hazardous’ drinkers will probably come as no surprise to acute physicians working elsewhere in the UK. In fact this figure may have been an under-estimate given that the number of units consumer per week was not documented in 30% of clerking records. The demographic shift away from the stereotype ‘middle-aged male’ drinker is also apparent with large numbers of females aged 40-59 falling into this category. Recent editions of this journal would not seem complete without mention of training in practical procedures. In this issue the SAM trainee representatives have summarised the recent trainee survey in this area, providing some recommendations which will hopefully be incorporated into the new curriculum. Readers who are becoming tired of this subject can be reassured that this should be the final article relating to this for the time being! I hope this edition provides interesting reading and please keep the submissions coming – although the review articles are usually solicited by the editorial team, we will continue to consider any submitted article for publication, provided there is a clear teaching message for those working in the field of Acute Medicine. Any feedback on the articles included in this or previous editions would also be welcome, and may be included in a future ‘viewpoint’ or ‘letters to the editor’ section.

As the COVID-19 pandemic progressed across the UK and Northern Ireland in March 2020, our otolaryngology department began to make preparations and changes in practice to accommodate for potentially large numbers of patients with COVID-19 related respiratory illness in the hospital. We retrospectively reviewed the number of non-elective admissions to our department between the months of January and May in 2019 and 2020. A significant reduction in admissions of up to 94% during the months of the pandemic was observed. Our practice shifted to manage patients with epistaxis and peritonsillar abscess on an outpatient basis, and while prospectively collecting data on this, we did not observe any significant adverse events. We view this as a positive learning point and change in our practice as a result of the COVID-19 pandemic.

The tribe presents a problem for the historian of the modern Middle East, particularly one interested in personalities, subtleties of culture and society, and other such “useless” things. By and large, tribes did not leave their own written records. The tribal author is a phenomenon of the present or the recent past. There are few twentieth century tribal figures comparable to the urban personalities to whose writings and influence we owe our understanding of the social, intellectual, and political history of the modern Middle East. There is next a larger problem of record keeping to contend with: the almost complete inaccessibility of official records on the postcolonial Middle East. It is no wonder that political scientists and anthropologists are among the best regarded custodians of the region's twentieth century history; they know how to make creative and often eloquent use of drastically limited tools. For many decades, suspicious governments have inhibited historians from carrying out the duties of their vocation. This is one reason why the many rich and original new monographs on Saddam Hussein's Iraq are so important. If tribes are on the margins of the records, and the records themselves are off limits, then one might imagine why modern Middle Eastern tribes are so poorly conceived in the scholarly imagination.

AbstractMeasurements made with the COSMOS machine on deep objectiveprism photographs taken with the UK 1.2m Schmidt Telescope are being used to obtain approximate redshifts (accurate to ~ 0.01 in z) for large numbers of galaxies in fields near the South Galactic Pole. The data are suitable for investigations of the distribution of galaxies, such as the detection of large-scale density enhancements or voids.

AbstractBaseline toxicity measurements established discriminating concentrations of pirimicarb and demeton-S-methyl guaranteed to kill susceptible examples of Aphis fabae Scop., Sitobion avenae (F.), Metopolophium dirhodum (Wlk.) and Rhopalosiphum padi (L.) in the dip-test, the FAO-recommended method for detecting resistance in aphids. There was no evidence for resistance to either insecticide in field-collected populations of aphids from various parts of the UK or amongst variants of S. avenae characterised by staining their esterases after electrophoresis. New, simple techniques for rearing large numbers of colonies of cereal aphids are described.

Human migration involves moving to a new permanent or semi-permanent location. Whether on an individual basis, in small groups or in large numbers, whether due to economic necessity (emigrants), sociocultural strife or the effects of war (refugees), it can contribute to stress in the mobile along with the settled population. Uncertainty then, increases the risk of psychosomatic disease in those relocating because of the changes in their personal/social support networks. The available healthcare for the displaced may not address their health needs adequately. Chapter 12 deliberates on this. Gender-related issues, with a female preponderance as victims come to the fore in displaced populations. These include the health effects of domestic and sexual violence or gender-based violence. International organisations, including the UN, the WHO, and FIGO, along with organisations from various countries that promote women's and children's health, have developed guidelines, and attempted to engender political will to endeavour to stop this preventable morbidity. Nevertheless, it persists with a biopsychosociocultural impact, and can be fatal. Unwanted pregnancies can result from gender-based violence or failed contraception with the pregnant woman seeking termination (abortion). Annually, about 42 million women resort to illegal methods of abortion, and risk grievous harm due to a lack of legalized services. Female genital mutilation, a form of gender-based violence with genitourinary sequelae that is carried out on girls, has global implications. It prevails due to cultural acceptance, despite major health consequences. It is illegal in the UK, and the RCOG has developed guidelines. Vignettes in this chapter illustrate these gender-related health issues.

The dynamism of elements of the archive profession has been particularly apparent over the past two decades as change and innovations have shaken up a profession previously perceived, perhaps not always unfairly, as pedestrian and static. The impetus for change has come both from outside and within the archive community. The lack in the UK of a national legislative framework covering the collecting of all types of archives, and an increased awareness of both the research and commercial value of historical records, have encouraged an expansion both in the types of organisations collecting archives and in the types of archives being collected. The shifting focus of attention of professional historians away from a preoccupation with ‘official’ records and the encouragement of more source-based teaching, both in schools and at undergraduate level, have facilitated such changes. The archive profession, however, is very aware that collecting by itself is not enough, and while lack of resources means that most archivists are still embarrassed by backlogs of material that have not been catalogued as fully as they would wish, greater attention is being focused on issues such as the need to widen access to archive collections, to increase security within repositories and to promote a greater understanding of conservation techniques.

Currently, in excess of 650 million broiler chickens are produced per annum in the UK.The rearing of these animals on large numbers of geographically dispered sites necessitates their transportation to centralised processing plants for slaughter. Birds are transported in containers in which behaviour, including any thermoregulatory component, will be restricted. The design of the container and the vehicle and the external climatic conditions will have profound effects upon the immediate environment of the birds. In transit they may be exposed to a variety of potential stressors including the thermal demands of this transport microenvironment, motion, acceleration, vibration, impacts, fasting, withdrawal of water, social disruption and noise. The adverse effects of these factors and their combinations may range from discomfort and mild aversion to death. Mortalities in transit are generally 0.4% or less but this may represent approximately 2 million birds per annum in the UK. It is estimated that up to 40% of the mortalities observed at the processing plant are a consequence of “stress”. It is thus essential from the standpoints of both animal welfare and productivity to optimise commercial poultry transport conditions and to provide the sound scientific basis for legislation relating to vehicles and transport practices. Although examination of the existing literature reveals that thermal stress is acknowledged as a major hazard during animal transportation it has been poorly characterised under practical conditions and the interactions between the animals and the complex thermal microenvironments clearly require more rigorous analyses.
