Abstract (sommario):
Progenetic specimens of Allocreadium neotenicum Peters, 1957 are described from water beetles, Hydroporus rufifrons, an endangered species, and Agabus paludosus from northern England and Scotland, and as non-ovigerous metacercariae from Agabus melanarius from southern England. Morphologically, the worms are identical to A. neotenicum described from water beetles in North America. Molecular phylogenetic estimates based on 28S rDNA sequences show these British specimens as more closely related to the North American freshwater fish parasite Allocreadium lobatum Wallin, 1909 than to the European species A. isoporum (Looss, 1894). A. lobatum shows a predilection for progenesis and may be a senior synonym of A. neotenicum. Based on the molecular phylogeny, the genus Pseudallocreadium Yamaguti, 1971 is considered synonymous with Allocreadium and the two species assigned to that genus, P. neotenicum and P. alloneotenicum (Wootton, 1957) are returned to Allocreadium.

Abstract (sommario):
Knowledge of the impacts of invasive species is important for their management, prioritisation of control efforts and policy decisions. We investigated how British and Irish botanical experts assessed impacts at smaller scales in areas where they were familiar with the flora. Experts were asked to select the 10 plants that they considered were having the largest impacts in their areas. They also scored the local impacts of 10 plant species that had been previously scored to have the highest impacts at the scale of Great Britain. Impacts were scored using the modified classification scheme of the EICAT framework (Environmental Impact Classification for Alien Taxa). A total of 782 species/score combinations were received, of which 123 were non-native plants in 86 recording areas. Impatiens glandulifera, Reynoutria japonica and Rhododendron ponticum were the three species considered to have the highest impacts across all regions. Four of the species included in the list of the 10 highest impact species in Great Britain were also in the top 10 of species reported in our study. Species in the higher impact categories had, on average, a wider distribution than species with impacts categorised at lower levels. The main habitat types affected were woodlands, followed by linear/boundary features and freshwater habitats. Thirty-nine native plant species were reported to be negatively affected. In comparison to the overall non-native flora of Britain and Ireland, the lifeform spectrum of the species reported was significantly different, with higher percentages of aquatic plants and trees, but a lower proportion of annuals. The study demonstrates the value of local knowledge and expertise in identifying invasive species with negative impacts on the environment. Local knowledge is useful to both confirm national assessments and to identify species and impacts on native species and habitats that may not have gained national attention.

Abstract (sommario):
We analysed the licences issued by British local government authorities under the Dangerous Wild Animals Act 1976, which regulates the private keeping of wild animals categorised as “dangerous”, to assess the scope and scale of private keeping of dangerous wild animals in Great Britain. Results are compared with historical data from England and Wales, showing that there has been an overall decrease both in the total population of dangerous wild animals privately kept under licence and the number of licences, resulting primarily from a decrease in the farming of wild boar and ostrich, and from certain other species no longer requiring a licence to be kept. Nonetheless, the private keeping of dangerous wild animals remains prevalent, with a total population of 3950 animals kept under licence, and at least one-third of local authorities in Britain licensing keepers of one or more such animals. The population of non-farmed dangerous taxa has increased by 59% in 20 years, with notable increases in crocodilians (198%), venomous snakes (94%), and wild cats (57%). We present evidence that the average cost of a licence to keep dangerous wild animals has fallen over time, and that there is a negative association between cost and licensing. The current schedule of species categorised as dangerous is compared to a formally recognised list of species kept in zoos assessed by risk to the public. Problems with the legislation, enforcement of the licensing system, and animal welfare for privately kept dangerous wild animals are identified and discussed.

Abstract (sommario):
Great Britain and elsewhere have detected atypical scrapie infection in sheep with PrP genotypes thought to be genetically resistant to the classical form of scrapie. DNA sequencing of the PrP gene of British atypical scrapie cases (n=69), classical scrapie cases (n=59) and scrapie-free controls (n=138) was undertaken to identify whether PrP variants, other than the three well-characterized polymorphic codons, influenced susceptibility to atypical scrapie infection. Four non-synonymous changes, M112T, M137T, L141F and P241S, were detected that are most probably associated with the A136R154Q171 haplotype. Only the PrP variant containing a phenylalanine residue at amino acid position 141 was found to be associated more commonly with the atypical scrapie cases. In addition to the single nucleotide polymorphisms associated with the ARQ allele, two out of nine atypical scrapie cases with the ARR/ARR genotype were found to contain a 24 bp insertion, leading to an additional octapeptide repeat. In terms of PrP genetics, one classification of the GB scrapie cases examined in this study would place animals carrying any homozygous or heterozygous combination of ARR, AHQ or AF141RQ alleles, or any one of these alleles when paired with ARQ, as being susceptible to atypical scrapie infection, and animals heterozygous or homozygous for VRQ or homozygous for ARQ as being susceptible to classical scrapie disease. The AHQ PrP allele was associated with the highest incidence of atypical scrapie (263 per 100 000 alleles), whilst VRQ was associated with the lowest incidence (10 per 100 000 alleles).

Abstract (sommario):
SUMMARYExamples of the apparently stochastic nature of freshwater fish helminth communities illustrating the erratic and unpredictable occurrence and distribution of many species are provided for six species of fish from several localities throughout Britain. By focussing on parasite colonization strategies two categories of helminths are recognized: autogenic species which mature in fish and allogenic species which mature in vertebrates other than fish and have a greater colonization potential and ability. Three groups of fish are distinguished: salmonids, in which helminth communities are generally dominated by autogenic species which are also responsible for most of the similarity within and between localities; cyprinids, in which they are dominated by allogenic species which are also responsible for most of the similarity within and between localities; and anguillids, whose helminth communities exhibit intermediate features with neither category consistently dominating nor providing a clear pattern of similarity. Recognition and appreciation of the different colonization strategies of autogenic and allogenic helminths in respect of host vagility and ability to cross land or sea barriers and break down habitat isolation, and their period of residence in a locality, whether transient or permanent, provides an understanding of, and explanation for, the observed patchy spatial distribution of many helminths. Comparison with other parts of the world indicates that colonization is a major determinant of helminth community structure.

Testo completo
Abstract (sommario):
This thesis is an historical analysis of the culture of science and its use of animals in experiments by the British military and in medical scientific research, and its regulation by law, during the period 1947 to 1965. The overall aim of this thesis is to demonstrate the gendered nature of scientific experimentation on animals in mid-twentieth century Britain. To do this, it addresses two aspects of animal experimentation; firstly, exploring how scientific research forms power-knowledge relations through the use of nonhuman animals. Secondly, this thesis analyses the intersection of animal use in science with that of the broader socio-cultural context, asking was science in mid-twentieth century Britain gendered? As a consequence, it explores the effects of this knowledge production upon animals and women. My findings are twofold: that the construction of scientific knowledge through the use of nonhuman animals was one that created subject-object binaries, and this had powerful and detrimental consequences for nonhuman animals. Secondly, this objectification of the nonhuman had resultant power-knowledge effects that reinforced the continuation of specific kinds of scientific knowledge and its associated masculinist ontology of positivism. Consequently, the effects of these power-knowledge relations were gendered and had implications for (and intersections with) normative representations of women at the time.

Testo completo
Abstract (sommario):
It is a well-established fact that all human societies have coexisted with and are dependent upon animals and it is increasingly recognized that the study of human-animal relationships provides vital insights into past human societies. Still this is yet to be widely embraced in archaeology. This thesis has examined human-animal interdependencies to explore the social identities and structure of society in the Norse North Atlantic. Benefitting from recent research advances in animal studies and the ever increasing volume of archaeological reports from Norse period archaeological excavations the North Atlantic this thesis was able to develop previous scholarship and define directions for future research. The thesis explored the role of animals in human society in the North Atlantic to reveal the complex Norse societies that existed. It revealed through human interdependencies with animals that these societies were far from homogeneous and had their own distinct identities with the individual islands as well as across the North Atlantic. The thesis achieved this by examining several important discrete but interlinked themes. These themes were divided into four chapters that focused on the individual aspects. This included an examination of previous North Atlantic Viking Age scholarship, consideration of human construction and perception of landscape through archaeological excavations, investigation of the role of domestic animals in human social activities, and an exploration of the role of domesticated animals in beliefs. Although these are all connected the structure of the thesis was deliberately chosen to restrict repetition, although given the interconnected nature of human social identities, society and worldview this was not entirely possible. This thesis addressed some of the most fundamental questions in Norse archaeology. Notably, through examination of human-animal interdependencies, it provided a detailed insight into how Norse society understood and perceived the world, and consequently the structure of Norse society and social identities.

Testo completo
Abstract (sommario):
This thesis examines the development of vivisection as a method of physiological research between 1875 and 1901 in Great Britain, by examining some of the arguments, discussions, and ideas put forth by physiologists for the utilisation of vivisection in their research. Because this study operates within the context of medical history, questions of legitimacy, scientific development, and professional image are lifted. The development of vivisection during this period took place with a larger shift in scientific practice playing out in the background, where experimentalism began overtaking the previously more analytical approach to medicine and the sciences. The First Royal Commission on Vivisection in 1875 marks the beginning of this study, and the discussions within allow for a more nuanced picture of the professional debates on the practice, where both proponents and sceptics at times found common ground. Technological and societal aspects were central to much of the argumentation for the further development of vivisection, with technology easing the practical aspects of the method, and the concept of the "gentleman" allowing British "vivisectors" to argue against charges of cruelty, pointing rather to continental schools of physiology as the culprits, whilst lifting the "humanity" behind animal experimentation in Great Britain. In conjunction with pointing out the importance of the method for the development of medical science, the Cruelty to Animals Act and the lobbying on behalf of the professional journals British Medical Journal and The Lancet helped legitimise the practice in Great Britain. The Act allowed vivisection under set circumstances, and the two journals served as megaphones for scientific development on behalf of vivisection, at times even openly criticising sceptical opinions. At the same time, some saw experimental research through vivisection as merely one aspect of medical practice. One which needed to gain foothold in order to help advance medical science for the larger benefit of all humanity.

Testo completo
Abstract (sommario):
Argulus foliaceus (Linnaeus, 1758) is a member of the branchiuran family Argulidae and has a worldwide distribution, causing major economic impacts for freshwater aquacultured fish species worldwide. In the UK, it has economic impacts for both aquaculture and sports fishing industries. Previous studies observed haemorrhagic and inflammatory responses after Argulus infection, which has been taken to support the idea that the parasite secretes chemicals during the feeding process to assist with the ingestion of blood and epithelial tissue. The present study suggests that the blood-feeding ectoparasite of fish, A. foliaceus, may use similar mechanisms for evading host immune responses to those used by sea lice and other haematophagous arthropods. No previous studies have directly investigated the nature of the bioactive compounds / proteins, assumed to be released from these ectoparasites, and which are considered to contribute to feeding processes and host-parasite interactions during infection. Thus, the work described in this thesis was undertaken with the objective of identifying, describing and characterising the secretory components that have previously been suggested to be secreted from glandular cells associated with the feeding appendages of Argulus foliaceus. The current study applied transcriptomic and proteomic techniques in conjunction with in situ methods to investigate known immunomodulatory genes that may serve a function in parasite-host interactions. Overall, the findings of this project have generated considerable additional knowledge concerning the biology of Argulus spp. and have provided a list of proteins that may be used by the parasite to facilitate feeding processes by secreting these active molecules into the host and hence modulating their immune defence mechanisms. This information can be used as a baseline for developing freshwater lice control strategies to help prevent the spread of Argulosis in aquaculture by applying vaccination as means of control using the candidate antigens described in this study to specifically target Argulus spp. Knowledge generated by the work described in this thesis can also contribute to the development of drugs for controlling Argulus or functional components of feed that may serve to protect fish against this parasite. Furthermore, data from this thesis enhances the knowledge of the distribution of toxin/venom or venom-like substances in crustaceans and arthropods in general.

Abstract (sommario):
AbstractFishes are among the most diverse and abundant groups of animals in the United Arab Emirates (UAE) and support fisheries that are second most important economic resource in the UAE, after oil. Most fishes are found in the coastal waters, and several species even live in the freshwater pools and streams up in the mountain wadis. Fishes are most abundant in the Gulf of Oman and gradually decline in both abundance and diversity passing through the Strait of Hormuz and towards the southwestern region of the Arabian Gulf, mirroring the increasingly extreme environmental conditions. As fish in the southern Gulf experience extreme environmental conditions, such as high temperatures, that would kill fish from populations elsewhere in the world they are of great scientific value for understanding how fish and their communities might respond to climate change, with studies demonstrating the behavioural and physiological changes that result from these extreme conditions. Fishes in the Emirates are, however, heavily overfished and like fishes elsewhere vulnerable to climate change resulting in Arabian Gulf fish now being vulnerable to local extinction. While fisheries are now being managed to protect vulnerable species, further management is required to protect fish populations for future generations.

Abstract (sommario):
Abstract The basis of animal protection legislation in Great Britain is the Protection of Animals Acts, the most important of which is, in England and Wales, the Protection of Animals Act 1911 (‘the 1911 Act’) and, in Scotland, the Protection of Animals (Scotland) Act 1912 (‘the 1912 Act’). It is in these statutes that the legal meaning of cruelty is set out. The 1911 and 1912 Acts are, in all essentials, identical; the reason for there being two separate pieces of legislation is historical. That of 1911 was principally a consolidation Act, by which means the existing law is, for the sake of convenience, brought together and restated in a single statute. At the time, the extent of the protection provided by Scottish law differed from the rest of Britain in a number of important respects and, by definition, it is inappropriate to introduce significant legislative change by means of a consolidation Act. Accordingly, in order to secure uniformity, it was necessary to introduce separate legislation in respect of Scotland.

Abstract (sommario):
Abstract From Boëthius onward, nearly everyone who took a philosophic approach to the natural world acknowledged animals, vegetables, and minerals as the main (or only) genera of earthly things, and arranged them as had Aristotle, with animals closest to man and minerals the most distant. This Great Chain of Being had come under attack before, but in the mid-1700s naturalists struggled to accommodate two new discoveries: that the flower-like polyps of corals are animals (or zoophytes), and the regenerative powers of the freshwater hydra. The Great Chain reached the apex of its development in the work of Charles Bonnet, who however allowed that some individual genera may not fit neatly into a linear scale, or indeed may deviate away, like branches from the trunk of a tree. This chapter concludes with the early, nuanced view of Jean-Baptiste Lamarck on continuity in nature (1778).

Abstract (sommario):
The article describes some of animal external characteristics and yield indicators. The mentioned animals are important for the country's agro-biodiversity, having valuable genes and their alleles, the loss of which will significantly limit the possibilities and efficiency of providing breeding works. Also Georgia is a country of great diversity of freshwater fish species that is facilitated due to the landscape diversity and richness of water resources. In addition, local breed varieties and populations are valuable because they are considered as the best adapted to local conditions and resistant to various diseases. Unfortunately, today their number is significantly reduced, their genetic purity is also in question. We consider the use of in- situ, ex- situ, in vivo, in vitro conservation methods to be the best way out of the situation.

Abstract (sommario):
SARS-CoV-2, the coronavirus responsible for the infectious disease COVID-19 (Gorbalenya et al 2020 (Opens in a new window)), was first detected in the human population in December 2019 (Zhu et al 2020 (Opens in a new window)). It has since spread to become a global pandemic. Previously, two other novel coronaviruses caused illness in the human population. The first, SARS-CoV (for Severe Acute Respiratory Syndrome) was recognised as a new illness in 2004 and the second, MERS-CoV (for Middle East respiratory syndrome) in 2012 (de Wit et al. 2016). These previous coronavirus outbreaks in humans occurred after bat coronaviruses passed through intermediate hosts (civet cats and camels, respectively) and then transmitted to infect humans (de Wit et al. 2016). SARS-CoV-2 infections in companion animals such as dogs, cats and ferrets and also in captive or farmed animals such as tigers and mink have been observed, likely as spill over events from contact with infected humans (WOAH 2022). There is now a large body of evidence from the United States that SARS-CoV-2 is capable of infecting white-tailed deer and that it can then spread further in the deer population (details in “What is the risk of SARS-CoV-2 being introduced into the cervid population in Great Britain?” (Defra, 2022). Assuming a worst-case scenario where SARS-CoV-2 is circulating within the UK deer population, this risk assessment was performed to determine whether handling and/or consuming UK-produced deer meat and/or offal may pose a risk of contracting SARS-CoV-2 in humans.
