Abstract The development of the film industry, especially Hollywood, which is currently a trendsetter, has introduced new prominent fictional characters. This is supported by technological advancements in graphics and computer visual effects. Animals are living creatures that are often used as references for the development of fictional characters, icons, and characterizations, not only in terms of physical appearance but also their characteristics. For example, this has brought about a new trend in the enhanced depiction of fable stories and also provides an opportunity to introduce unique wildlife from a particular region. It not only introduces local animals specific to an area but also enables the introduction of local culture. Indonesia itself has many regions that possess distinctive animals and cultural values with artistic significance. One example is the rhinoceros, which is an endemic animal of the western part of the island of Java (Banten), the buffalo from Sumatra (Padang), and the cockatoo from Sumatra (Lampung). At the end of this study, it will encompass the design of interesting characters inspired by the unique animals of Indonesia's regions, depicted as martial arts characters with distinct regional appearances. This aims to introduce not only the animal characters but also the culture of those regions. Keywords Wildlife; Endemic; Animal; Actions; Figures

The domestication and use of animals is an integral part of the history of technology, as beasts were used to improve the efficiency of agricultural, military, and transportation activities. Individuals and social groups often had to be introduced along with animal technologies, as the domestication, breeding, training, and handling of animals was a culture that could not be immediately learned. In the age of European empires, several ethnic groups were imported along with the animals that they tended. This article highlights the role of humans as part of animal technologies, as an important anthropological component when technologies that involve animals are introduced to new settlements and areas. Using three case studies in which animal technologies from Asia were introduced to other parts of the world, it can be seen that humans are an essential and integral component of animal technologies.

Sixteen species of introduced or alien aquatic amphibians and reptiles have been recorded from Singapore's Public Utilities Board reservoirs. Their presence in the wild state is largely due to members of the public abandoning their pets, or releasing animals to gain spiritual merit (fang sheng). The ban imposed by the Agri-Food and Veterinary Authority on the sale of most species of amphibians and reptiles will probably help to restrict the diversity of alien animal species in Singapore. However, the continued availability of hatchling red-eared terrapins in pet shops and live Chinese softshell turtles and American bullfrogs in markets does little to reduce the presence of these three alien species in local water bodies.

AbstractThe place of the non-human animal in the legal world has been questioned. Animals’ legal status as property has been probed on how to best protect their welfare. While this is significant for animals who are not on the farm, it might not be effective when considering animals raised for food. The case of the carabao, or the water buffalo, in the Philippines is seen as a hybrid. This article traces the development of the carabao in Philippine history during the nineteenth century. Through historical, archival, and legal research on animals, the carabao is situated as private property. Colonial instruments of control were introduced to protect the carabao from criminals. In its proper historical context, the classification of carabaos as property indeed highlighted the animal’s status as legally owned, which did not necessarily demean the animal’s relationship with the human peasant nor the carabao’s quality as an animal.

AbstractThis paper provides an overview of results from an Australian Research Council-funded project "Sentiments and Risks: The Changing Nature of Human-Animal Relations in Australia." The data discussed come from a survey of 2000 representative Australians at the capital city, state, and rural regional level. It provides both a snapshot of the state of involvement of Australians with nonhuman animals and their views on critical issues: ethics, rights, animals as food, risk from animals, native versus introduced animals, hunting, fishing, and companionate relations with animals. Its data point to key trends and change. The changing position of animals in Australian society is critical to understand, given its historic export markets in meat and livestock, emerging tourism industry with its strong wildlife focus, native animals' place in discourses of nation, and the centrality of animal foods in the national diet. New anxieties about risk from animal-sourced foods and the endangerment of native animals from development and introduced species, together with tensions between animals' rights and the privileging of native species, contribute to the growth of a strongly contested animal politics in Australia.

AbstractIn 1974–75 30 muskoxen Ovibos moschatus were introduced to the tundra of Poluostrov Taymyr, ten from Banks Island NWT, Canada and 20 from Nunivak Island, Alaska. Originally enclosed in large corrals near a special research station in the Bikada valley, at the east end of Ozero Taymyr, the animals were released in 1980/82. The first calf to survive infancy was born in 1978; since then the death rate has been extremely low. By July 1987 the population had risen to 230, running in 10–12 herds. Most of the animals still range close to the Bikada valley, but one herd of 40 animals has moved noth across the main range of Byrranga Gory. Bachelor bulls wander even farther afield, up to 300 km from the release site. In August 195 two bulls appeard at Mys Chelyuskina, the northernmost tip of the continent.

An animal’s capacity to suffer is a prerequisite for any animal welfare concern, and the minimization of suffering is a key aim of refinement research. In contrast to the traditional focus on avoiding or reducing negative welfare states, modern animal welfare concepts highlight the importance of promoting positive welfare states in laboratory animals. Reliable assessments of affective states, as well as the knowledge of how to elicit positive affective states, are central to this concept. Important achievements have been made to assess pain and other negative affective states in animals in the last decades, but it is only recently that the neurobiology of positive emotions in humans and animals has been gaining more interest. Thereby, the need for promotion of positive affective states for laboratory animals is gaining more acceptance, and methods allowing the assessment of affective states in animals have been increasingly introduced. In this overview article, we present common and emerging methods to assess affective states in laboratory rodents. We focus on the implementation of these methods into applied refinement research to identify achieved progress as well as the future potential of these tools to improve animal welfare in animal-based research.

El desarrollo histórico y normativo en Colombia sobre el trato y protección de los animales ha resultado en un cambio de paradigma. Su consideración como bienes muebles, ha evolucionado, a partir del Código Civil Colombiano, para reconocerles como seres sintientes. Esta distinción se reflejada, además, en la jurisprudencia tanto del Consejo de Estado como de la Corte Constitucional. En este sentido, una de las discusiones contemporáneas sobre la protección animal es el tratamiento e impacto sobre el territorio colombiano de los animales invasores, introducidos y exóticos, ya que, al tratarse de especies que no son nativas, afectan ineludiblemente la fauna del país. Este aspecto exige que el Estado deba enfrentarse a los desafíos de reconocimiento de su estatus. De este modo, este texto pretende identificar cómo se desenvuelve normativa y jurisprudencialmente el tratamiento de esta tipología de animales en el territorio colombiano.

Humankind has redistributed a large number of species outside their native geographic ranges. Although the majority of introduction attempts fail to establish populations, the cumulative negative effect of successful non-native species has been and will continue to be large. Historical records of land bird introductions provide one of the richest sources of data for testing hypotheses regarding the factors that affect the successful establishment of non-native populations. However, despite comprehensive summaries of global avian introductions dating back two decades only very recent studies have examined the successful establishment of non-native bird species worldwide. It is clear that a non-random pattern exists in the types of land bird species that have been chosen by humans to be introduced outside their native range. Out of the 44 avian families from which species have been chosen for introduction almost 70% of introduction attempts have been from just five families (Phasianidae, Passeridae, Fringillidae, Columbidae, Psittacidae). Notably, these families include game species, insectivorous song birds, and species from the pet trade. It has been hypothesised that the fate of introduced species may be determined in part by heritable characteristics that are shared by closely related taxa. In my analyses, I have used current comparative methods to demonstrate that intrinsic eco-physiological characteristics are significant predictors of the worldwide success of introduced land bird species. The results of my analyses contribute to a greater ecological understanding of the traits that correlate with the successful establishment of non-native species. Notably, the three major conclusions that I have drawn from this thesis are: 1. Non-random patterns of successful establishment exist for introduced land bird taxa that have experienced a repeated number of introduction attempts. This result supports the idea that introduced species have an inherent likelihood of either succeeding or failing to establish non-native populations. 2. Eco-physiological traits are important correlates for determining the variability in introduction outcome for non-native land bird species. With reliable information on introduction attempts and taxa-specific traits predictive models are possible that quantify the outcome of repeated introduction attempts across non-native species. 3. Islands are not universally less resistant than mainland regions to the successful establishment of non-native species. This perception is a reflection of the greater number of introduction attempts to islands rather than an effect of biotic resistance. Any differences in the success of introduction attempts can be attributed largely to differences in the proportion of introductions that have been made across biogeographic regions. I have highlighted that data are accessible for global analyses of the variability in the successful establishment of non-native species. Although establishment success is not a deterministic process, the characteristics of an introduced species can influence the probability of its succeeding. I have shown that with adequate eco-physiological information, and for introduced land bird species at least, this probability can be predicted. These results refute previous suggestions that the stochastic component of species introductions will always overshadow any emerging patterns of successful establishment among non-native populations.

Streszczenie:
The detrimental impact of invasive, non-native species on biodiversity conservation and ecosystem function is widely recognised. The invasion of predatory species can have particularly deleterious consequences on native species in the invaded range and there is an increasing awareness of, and necessity for, management action to minimise these impacts. There is a growing body of literature identifying the impacts of invasive species and priorities for conservation action. However, there is a noticeable gap between the rising scientific output regarding invasive species control and conservation measures, and the management action required to implement recommendations. The American mink (Neovison vison, hereafter mink) has been a recent focus of invasive species research and management. Mink are semi-aquatic mustelids and generalist predators and were introduced to countries around the world for fur farming. Feral populations have established across the introduced range with devastating consequences for native species, particularly birds and mammals. In the UK, mink are held partly responsible for the decline in water voles (Arvicola amphibius) and in Scotland in particular, breeding seabirds are significantly impacted by mink predation. Control of mink in North East Scotland has proven successful using an adaptive management, community-based approach but there is currently no equivalent project in the complex, coastal landscape of west Scotland. This study aimed to provide information that could refine and further develop management plans for mink in north and west Scotland by acquiring a better understanding of the ecology of mink in Scotland to inform the implementation of control. Mink were distributed across all but the far north of Scotland. There was spatial and temporal variation in the pattern and rate of their expansion which was attributed to landscape heterogeneity. In northwest Scotland, availability of suitable habitat was restricted to the coastline and consequently, the availability of prey was hypothesised to be limited to coastal areas. Indeed, the diet of mink in northwest Scotland had a greater input from marine resources than those in southwest Scotland, where habitat availability and, therefore, terrestrial food resources, extended inland. Landscape features were shown to affect the direction of colonisation, with mountains restricting and valleys facilitating dispersal. Population genetic studies confirmed that mink dispersal in northwest and northeast Scotland was limited by mountain barriers. Additionally, populations in northwest Scotland were likely to have originated from southwest Scotland. These results suggest that mink control should be primarily focussed in coastal habitats in west Scotland and that the risk of reinvasion from relatively close populations in northeast Scotland is minimal. Volunteer involvement in conservation projects is being accepted increasingly as a cost-effective way to gather ecological information and implement conservation over large spatial scales. The landscape of west Scotland, particularly in northern areas, is complex, remote and sparsely populated by humans which consequently creates challenges for executing mink control. Ecotourism boat operators were concerned about the presence of mink and their effect on local wildlife in coastal areas and were willing to volunteer in mink management. Consequently ecotourism boat operators could provide a key link between management recommendations and implementation. This study combined methodologies from ecological modelling, population genetics, chemical analyses and social science to address questions regarding invasive species management. This holistic approach has resulted in a thorough overview of the distribution and ecology of an invasive species as well as recommendations for management action and implementation that will be applicable to a range of invasive species.

In near-shore marine environments, two of the most prevalent anthropogenic disturbances affecting ecosystem diversity and function are the invasion of exotic species, and the release of toxic chemicals. Estuarine and harbour environments worldwide are dually subjected to high levels of toxic disturbance and ever increasing rates of invasion, via activities such as boating and shipping. It is not clear, however, whether the success of invasive species is influenced by the presence of toxic contaminants in these impacted environments. In particular, nonindigenous marine species (NIS) may be advantaged in chemically disturbed environments if they are more tolerant of toxicants. This thesis examines whether nonindigenous and native sessile invertebrate species have differential tolerance to a common aquatic contaminant, copper (Cu), which has links to both the invasion process (via its use in antifouling paints and the vector of hull fouling) and the modification of recipient environments (via human-mediated pollution). A series of laboratory- and field-based experiments showed that the cosmopolitan invasive bryozoans Watersipora subtorquata, Bugula neritina and Schizoporella errata are highly tolerant of copper pollution. The larvae and adults of W. subtorquata and B. neritina in particular were able to survive and grow in copper-polluted environments far exceeding most observed real-world levels (< 100 /??g 1-1). These nonindigenous species also showed very strong postexposure recovery. In contrast, the co-occurring native bryozoans Celleporaria nodulosa and Fenestrulina mutabilis demonstrated comparatively low tolerance to copper, with markedly reduced survival and fitness under Cu contaminated conditions, and inferior recovery abilities post-exposure. These findings were further supported by a long-term manipulative field experiment, examining the effect that varying levels of Cu exposure have on the structure and diversity of developing sessile invertebrate assemblages. Cu exposure decreased native species diversity by up to 50%, yet had no effect on NIS numbers. Consequently, in the presence of copper contamination, NIS dominated sessile communities, often resulting in substantial changes to community structure. Important insights were also gained into the nature of metal tolerance in NIS. Toxicity studies on larvae of the introduced bryozoan Bugula neritina revealed intraspecific differences in tolerance to Cu, associated with the level of pollution experienced by the adult source populations. There was also evidence of fitness costs related with increased Cu tolerance. In summary, we have found evidence that the success of invasive species is influenced by chemical contamination. NIS may be advantaged in contaminated estuaries relative to native species and this may assist in their establishment and persistence in new habitats.

Abstract In this expert opinion, two case studies of tick-borne diseases of domestic animals in Australia have been selected to illustrate how climate change can potentially influence the spread of introduced tick species and the pathogens they transmit. The first reports an incursion of canine monocytic ehrlichiosis (CME) into northern regions of Australia in April/June 2020 and the second describes the geographical expansion of bovine anaemia due to Theileria orientalis group (BATOG) across Australia since 2006. The introduction of novel pathogens into ecosystems exposed to climate change provides a unique opportunity to study disease dynamics in real time.

Streszczenie:
Abstract Plants and animals have evolved a variety of strategies to limit the negative fitness consequences of natural enemies (i.e. herbivores, predators, parasites and pathogens). Demographic bottlenecks occurring during the invasion process reduce the number of co-introduced natural enemies, providing opportunities to study rapid evolution in environments with different or reduced enemy loads. Enemy release theory provides a set of hypotheses and predictions about the role of natural enemies in the proliferation of invasive species. This body of theory includes the Enemy Release Hypothesis (ERH) and the related Evolution of Increased Competitive Ability Hypothesis (EICA), but there is often confusion about these hypotheses and the data needed to test them. We introduce a simple, general model of enemy release to identify and clarify some of the key assumptions and predictions implicit in enemy release theory and its impacts on invasion. Although introduced populations likely benefit from a reduction in the direct fitness impacts of natural enemies in the early stages of invasion, an evolutionary shift in resource allocation from defence to growth and reproduction is much less likely and depends on a delicate balance between the fitness costs and benefits of defence and the fitness impacts of natural enemies in both the native and introduced ranges. Even when the abundance of natural enemies is lower in the introduced range, the majority of scenarios do not favour evolution of less defended genotypes that are more competitive or more fecund, contrary to predictions of EICA. Perhaps surprisingly, we find that the level of damage by natural enemies in field surveys is not generally a good parameter for testing enemy release theory. Instead, common garden experiments characterizing fitness reaction norms of multiple genotypes from the native and introduced range are crucial to estimate the historic rate of adaptive evolution or predict it into the future. Incorporating spatial autocorrelation and methods from population genetics can further improve our understanding of the role of enemy release and evolution in the proliferation of invasive species.

AbstractThe preference for native species, along with its concomitant antipathy toward non-natives, has been increasingly criticized as incoherent, obsolete, xenophobic, misanthropic, uncompassionate, and antithetical to conservation. This essay explores these criticisms. It articulates an ecological conception of nativeness that distinguishes non-native species both from human-introduced and from invasive species. It supports, for the most part, the criticisms that non-natives threaten biodiversity, homogenize ecological assemblages, and further humanize the planet. While prejudicial dislike of the foreign is a human failing that feeds the preference for natives, opposition to non-natives can be based on laudatory desires to protect natural dimensions of the biological world and to prevent biological impoverishment. Implications for our treatment of non-native, sentient animals are explored, as well as are questions about how to apply the native/non-native distinction to animals that share human habitats and to species affected by climate change.

AbstractWe provide a conceptual primer for sexual selection and conflict, mating systems, and socio-sexual behaviors and patterns among animals, largely with mammalian and cetacean examples. The important roles of mate choice are discussed (including female choice) and the occasional fluidity of sexual roles. An overview of topics pertinent to sex and behavior is described, including evolutionary drivers (the concept of “why sex after all?”) followed by general mammalian and cetacean mating strategies and tactics. We describe mating systems (monogamy, polygyny, polyandry, polygynandry) with the present understanding that most cetaceans do not have monogamous or polyandrous mating systems. The primer includes brief introductions to historical knowledge and highlights emerging areas of research within the field of sex in cetaceans, with context for other chapters of this book. As part of overall sexual behavior, alloparental care, female reproductive senescence, and non-procreative behaviors including homosexual and necrocoital mating are also introduced.

AbstractIn his prominent book Regeneration (1901), T.H. Morgan’s collected and synthesized theoretical and experimental findings from a diverse array of regenerating animals and plants. Through his endeavor, he introduced a new way to study regeneration and its evolution, setting a conceptual framework that still guides today’s research and that embraces the contemporary evolutionary and developmental approaches.In the first part of the chapter, we summarize Morgan’s major tenets and use it as a narrative thread to advocate interpreting regenerative biology through the theoretical tools provided by evolution and developmental biology, but also to highlight potential caveats resulting from the rapid proliferation of comparative studies and from the expansion of experimental laboratory models. In the second part, we review some experimental evo-devo approaches, highlighting their power and some of their interpretative dangers. Finally, in order to further understand the evolution of regenerative abilities, we portray an adaptive perspective on the evolution of regeneration and suggest a framework for investigating the adaptive nature of regeneration.

In many scientific papers, the term biosecurity measures (BSMs) are defined as the implementation of segregation, sanitation or management procedures specifically designed to reduce the likelihood of the introduction, establishment, survival or spread of a potential pathogen into, within or from a farm or geographical area. The main BSMs (general external and internal BSMs related to newly introduced animals, farm workers, family members, visitors and service providers, vehicles, tools and equipment, location of farms, water and feed, control programs, management practices, handling of raw materials, work procedures, training, plans and records), based on literature data, guides, instructions, recommendation codes and checklists, are presented in the paper. In addition to the BSMs mentioned, the importance of segregation, cleaning and disinfection is emphasized. The most important and effective part of biosecurity is to keep infected animals and contaminated material away from non-infected animals. Cleaning and disinfecting barns, vehicles and equipment, especially boots and clothing, is a very effective way to minimize the transmission of disease to or between animals. It is very important to implement BSMs as a long-standing and successful practice on farms to maintain animal health. These measures should be included in a comprehensive biosecurity plan, which is tailored to farms characteristics and needs that must be fully implemented. A biosecurity plan and the design and implementation of biosecurity programs should address how farmers handle animals, vehicles and human access to the farm, as well as animal health and work procedures. Key BSMs should be followed on an ongoing basis and, working with veterinarians, farmers themselves can play an important role in keeping animals and production as healthy as possible. It is important to regularly assess the implementation of BSMs using appropriate questionnaires, which can highlight deficiencies that should be addressed immediately.

The Ust-Кubinsky District group of the European bison (Bison bonasus) is introduced, allopatric in relation to the main areas of the bison, and unique in its biological and ecological features, and has about 130 animals of different age and sex groups freely inhabiting and reproducing in a sharply continental climate. Helminthofaunistic studies of the population have almost never been carried out before. The study describes the results of helminthovoscopic studies conducted using the Kotelnikov flotation method and direct sedimentation method (sequential washing). A total of 35 samples were studied. It was found that the gastrointestinal parasite fauna in the studied group was depleted and represented by nematodes of the suborder Strongylata (with the prevalence of invasion of 40%), and protozoa of the genus Eimeria (with the prevalence of invasion of 37.1%). Mixed invasion of both taxonomic groups of endoparasites was observed in 17%. This can be explained by the peculiarity of the trophic and chorological relations of the parasite host, the European bison, in the studied territory. It should be noted that these studies are preliminary, and it is necessary to conduct them in different periods of the year, particularly, in the summer-autumn, with animal groups separated by age, if possible, since it is known that the parasite fauna of young and adult animals can differ significantly.

Artificial neural networks have been applied to pattern recognition, prediction and control because they have abilities of learning, generalization and nonlinear mapping. These conventional neural networks have not had “intelligence” yet. In pattern recognition, the recognition rate can be low when there are some noises in recognized patterns. Not so many neural networks have been reported that introduce the structural and functional characteristics of the brain obtained by the progress of neurophysiology. In this study, we focused on the cerebral neocortex, which is the most developed in human to be compared with the other animals and deals with recognition, language and imagination, introduced its characteristics of uniform, hierarchical, column structures and six layers to neural networks and investigated the possibility of emerging its functional characteristics of the human brain.

The research purpose was to study seasonal characteristics of nematodirosis manifesting in the Edilbaev sheep introduced into the Kulunda Steppe of the Altai Region. Fecal samples collected from spontaneously infected animals were studied by coproovoscopic method per Fülleborn. The Nematodirus infection in sheep in different seasons of the year was characterized in view of incidence rates (prevalence, %) and infection intensity (average number of eggs per gram of feces (egg/g) per one studied and infected animal). A total of 240 fecal samples were examined. It was found that annual dynamics of the epizootic process was typical for Nematodirus. The minimum Nematodirus infection rate in sheep was recorded in July (prevalence = 10.0%) with an increase to 68.8% observed in August and maximum values of 95.6% recorded in October. Similar results were detected for the intensity of infectious process of nematodirosis, namely, the maximum number of eggs in fecal samples per examined and infected animal was recorded in autumn, 193.1 and 235.9 egg/g, accordingly, and the minimum in April, 2.0 and 20.6 egg/g, accordingly. The summer-autumn seasonal pattern of the infectious process of nematodirosis in sheep was due to the maximum contamination of land with helminth eggs during this period.

Frequent uncontrolled use of feed antibiotics in intensive production of feedstuff has led to the formation of resistant strains of pathogenic bacteria. The use of feed antibiotics has resulted in increased productivity of farm animals due to the suppression of the pathogenic microflora of the digestive system. The situation is exacerbated by animal stresses due to poor feed quality and poor conditions. Often there are cases of dysbacteriosis, especially in young animals, reduced cows’ reproduction, excess live weight of young animals, increased infectious and alimentary (caused by defective unbalanced feeding) origin is growing diseases. Based on the results of scientific of previous grants supported by the State Committee on Science of the Republic of Armenia and the ANSEF at the laboratory of Artsakh Scientific Center was developed a new technology for enrichment of feedstuff in accordance with the main nutritional resources of Artsakh and with probiotic lactic acid bacteria Enterococcus durans KE5, Lactobacillus acidophilus 1991, Streptococus lactis and Streptococcus termophilus. The data show that after the use of probiotic bacteria, the quality of the feed increases. The activity of probiotic bacteria suppresses the growth of fungi and pathogenic microflora. The results of the content of amino acids and protein during silage of the green mass of corn are given in Table 1. Table 1.

Conclusions The property of lactic acid bacteria to synthesize lactic acid is used for silage of green biomass. However, we have shown that the use of a consortium of LAB strains and yeast with probiotic properties leads to an increase in the content of protein and essential amino acids in silage, a decrease in its infectivity, and the effectiveness of the method used depends on the source and nature of the used method of green biomass and strains. Therefore, the use of starter culture from the consortium of investigated probiotics LAB and yeast in silage should be introduced as widely as possible, as they have a positive effect on the health of animals.

The American mink is an introduced species for the Kirov Region. The analysis of helminth infection of the American mink was carried out in urban conditions and natural biocenoses of the Kirov Region (floodplains of the Vyatka, Kama, Cheptsa and Moloma Rivers) in the north-east of the European part of Russia. The method of complete helminthological dissection was used to study 109 carcasses of the American mink from natural biocenoses and urbanized landscapes of the city of Kirov and other settlements of the Kirov Region (residential areas). In the studied animals, species, sex, age, weight and fatness of the animal were determined. Age was determined by the method of V. G. Klevezal. Eighteen species of parasitic worms belonging to 3 classes were identified, namely, trematodes (4 species), nematodes (13 species), and cestodes (1 species). Five new species were found for the Kirov Region including Metorchis bilis (Braun, 1890), Crenosoma taiga (Skrjabin et Petrov, 1928), and Mustelivingylus skrjabini (Romanov et Kontrimavichus, 1962). Of these, 8 species were found in urban areas. Most often, infection occurred with 4 helminth species, Aonchotheca putorii, Aonchotheca mucronata, Crenosoma taiga, and Skrjabingylus nasicola. Epizootological and epidemiological danger is posed by Trichinella nativa. In minks, the bladder (A. mucronata) and frontal sinuses (Sk. nasicola) are often affected.

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.

The avian influenza virus, subtype H9N2 subtype, defined as having a low pathogenicity, causes extensive economical losses in commercial flocks, probably due to management and synergism with other pathogens. AIV H9N2 was first identified in Israel in the year 2000, and since then it became endemic and widespread in Israel. Control by vaccination of commercial flocks with an inactivated vaccine has been introduced since 2007. In face of the continuous H9N2 outbreaks, and the application of the vaccination policy, we aimed in the present study to provide a method of differentiating naturally infected from vaccinated animals (DIVA). The aim of the assay would be detect only antibodies created by a de-novo infection, since the inactivated vaccine virus is not reproducing, and might provide a simple tool for mass detection of novel infections of commercial flocks. To fulfill the overall aim, the project was designed to include four operational objectives: 1. Evaluation of the genetic evolution of AIV in Israel; 2. Assessment of the diagnostic value of an NS1 ELISA; 3. NS1 ELISA as evaluation criteria for measuring the efficacy of vaccination against H9N2 AIV; 4. Development of an AIV H9 subtype specific ELISA systems. Major conclusion and implications drawn from the project were: 1. A continuous genetic change occurred in the collection of H9N2 isolates, and new introductions were identified. It was shown thatthe differences between the HA proteins of viruses used for vaccine productionand local fieldisolatesincreasedin parallelwith the durationand intensity ofvaccine use, therefore, developing a differential assay for the vaccine and the wild type viruses was the project main aim. 2. To assess the diagnostic value of an NS1 ELISA we first performed experimental infection trials using representative viruses of all introductions, and used the sera and recombinant NS1 antigens of the same viruses in homologous and heterologous NS1 ELISA combination. The NS1 ELISA was evidently reactive in all combinations, and did not discriminate significantly between different groups. 3. However, several major drawbacks of the NS1 ELISA were recognized: a) The evaluation of the vaccination effect in challenged birds, showed that the level of the NS1 antibodies dropped due to the vaccination-dependent virus level drop; b) the applicability of the NS1-ELISA was verified on sera of commercial flocks and found to be unusable due to physico-chemical composition of the sera and the recombinant antigen, c) commercial sera showed non-reactivity that might be caused by many factors, including vaccination, uncertainty regarding the infection time, and possibly low antigen avidity, d) NS1 elevated antibody levels for less than 2 months in SPF chicks. Due to the above mentioned reasons we do not recommend the application of the DIVA NS1 ELISA assay for monitoring and differentiation AIV H9N2 naturally-infected from vaccinated commercial birds.

Streszczenie:
In September 2006 an outbreak of 'Bluetongue like' disease struck the cattle herds in Israel. Over 100 dairy and beef cattle herds were affected. Epizootic hemorrhagic disease virus (EHDV) (an Orbivirusclosely related to bluetongue virus (BTV)), was isolated from samples collected from several herds during the outbreaks. Following are the aims of the study and summary of the results: which up until now were published in 6 articles in peer-reviewed journals. Three more articles are still under preparation: 1. To identify the origin of the virus: The virus identified was fully sequenced and compared with the sequences available in the GenBank. It appeared that while gene segment L2 was clustered with EHDV-7 isolated in Australia, most of the other segments were clustered with EHDV-6 isolates from South-Africa and Bahrain. This may suggest that the strain which affected Israel on 2006 may have been related to similar outbreaks which occurred in north-Africa at the same year and could also be a result of reassortment with an Australian strain (Wilson et al. article in preparation). Analysis of the serological results from Israel demonstrated that cows and calves were similarly positive as opposed to BTV for which seropositivity in cows was significantly higher than in calves. This finding also supports the hypothesis that the 2006 EHD outbreak in Israel was an incursive event and the virus was not present in Israel before this outbreak (Kedmi et al. Veterinary Journal, 2011) 2. To identify the vectors of this virus: In the US, Culicoides sonorensis was found as an efficient vector of EHDV as the virus was transmitted by midges fed on infected white tailed deer (WTD; Odocoileusvirginianus) to susceptible WTD (Ruder et al. Parasites and Vectors, 2012). We also examined the effect of temperature on replication of EHDV-7 in C. sonorensis and demonstrated that the time to detection of potentially competent midges decreased with increasing temperature (Ruder et al. in preparation). Although multiple attempts were made, we failed to evaluate wild-caught Culicoidesinsignisas a potential vector for EHDV-7; however, our finding that C. sonorensis is a competent vector is far more significant because this species is widespread in the U.S. As for Israeli Culicoides spp. the main species caught near farms affected during the outbreaks were C. imicolaand C. oxystoma. The vector competence studies performed in Israel were in a smaller scale than in the US due to lack of a laboratory colony of these species and due to lack of facilities to infect animals with vector borne diseases. However, we found both species to be susceptible for infection by EHDV. For C. oxystoma, 1/3 of the Culicoidesinfected were positive 11 days post feeding. 3. To identify the host and environmental factors influencing the level of exposure to EHDV, its spread and its associated morbidity: Analysis of the cattle morbidity in Israel showed that the disease resulted in an average loss of over 200 kg milk per cow in herds affected during September 2006 and 1.42% excess mortality in heavily infected herds (Kedmi et al. Journal of Dairy Science, 2010). Outbreak investigation showed that winds played a significant role in virus spread during the 2006 outbreak (Kedmi et al. Preventive Veterinary Medicine, 2010). Further studies showed that both sheep (Kedmi et al. Veterinary Microbiology, 2011) and wild ruminants did not play a significant role in virus spread in Israel (Kedmi et al. article in preparation). Clinical studies in WTD showed that this species is highly susceptibile to EHDV-7 infection and disease (Ruder et al. Journal of Wildlife Diseases, 2012). Experimental infection of Holstein cattle (cows and calves) yielded subclinical viremia (Ruder et al. in preparation). The findings of this study, which resulted in 6 articles, published in peer reviewed journals and 4 more articles which are in preparation, contributed to the dairy industry in Israel by defining the main factors associated with disease spread and assessment of disease impact. In the US, we demonstrated that sufficient conditions exist for potential virus establishment if EHDV-7 were introduced. The significant knowledge gained through this study will enable better decision making regarding prevention and control measures for EHDV and similar viruses, such as BTV.

Los Cerros Orientales representan una gran oferta de biodiversidad y servicios ecosistémicos para la capital y para la región Andina allí podemos encontrar el Capitán de la sabana (Eremophilus mutisii), la Guapucha (Grundulus bogotensis), el Capitán enano (Trichomycterus bogotense), el Bocachico (Prochilodus magdalenae), el Pez Cuchilla de Cristal (Sternopygus aequilabiatus), y el corroncho o cucha (Cordylancistrus daguae). Algunas de estas especies representan una fuente de proteínas para el consumo humano, otras aportan nutrientes a sus ecosistemas específicos a través de los desechos nitrogenados que sirven para alimento de las plantas que viven en estos lugares. Sin embargo, su presencia en los cerros puede verse amenazada por muchos factores como la sobrepesca, la implantación de especies exóticas principalmente de trucha arcoíris (Oncorhynchus mykiss), la tala de árboles que afecta el hábitat de las especies, así como la mínería, y el manejo inadecuado de basuras en los ríos. Este último además de afectar negativamente al suelo, también pueden deteriorar las fuentes hídricas donde habitan estos organismos y ocasionar alteraciones en la cadena trófica. A todo esto también debemos añadir el mal uso de los cuerpos de agua como la captación ilegal del agua, ocupación de los cauces de los ríos, esto representa el 40% de las amenazas que tienen los cerros. Para hacer frente a todas estas amenazas además del consumo responsable de estos organismos, que implica respetar las tallas mínimas de captura para impedir su explotación excesiva, se debe conocer todas las medidas de control que contribuyen a su conservación. Por ejemplo, no introducir especies ícticas exóticas, no arrojar sustancias contaminantes o tóxicas en los cuerpos de agua, denunciar el uso de los recursos naturales renovables sin la previa obtención de los permisos correspondientes. De forma directa reconocer las especies a nivel morfológico, permitirá hacer conciencia del proceso de conservación que debemos realizar. De esta manera, ayudaremos a frenar el avance de los procesos de deterioro relacionados con la urbanización para que nuestras futuras generaciones puedan contemplar, disfrutar y beneficiarse de los peces de nuestros Cerros Orientales.
