Wildlife Disease
Wild animals, domestic animals and humans share a large and increasing number of infectious diseases, known as zoonoses. The continued globalization of society, human population growth, and associated landscape change further increase the interactions between humans and other animals, thereby facilitating additional infectious disease emergence. Contemporary diseases of zoonotic origin include SARS, Lyme disease and West Nile virus. Disease emergence and resurgence in populations of wild animals are considered an important topic for conservationists, as these diseases can affect the sustainability of affected populations and the long-term survival of some species. Examples of such diseases include chytridiomycosis in amphibians, chronic wasting disease in deer, white-nose syndrome, in bats, and devil facial tumour disease in Tasmanian devils. Prevention Culling Disease outbreaks in wild animals are sometimes controlled by killing infected individuals to prevent transmission ...

Dead Bd-infected Atelopus Limosus At Sierra Llorona (posed To Show Ventral Lesions And Chytridiomycosis Signs)
Death is the Irreversible process, irreversible cessation of all biological process, biological functions that sustain an organism. For organisms with a brain, death can also be defined as the irreversible cessation of functioning of the whole brain, including brainstem, and brain death is sometimes used as a legal definition of death. The remains of a former organism normally begin to Decomposition, decompose shortly after death. Death is an inevitable process that eventually occurs in Biological immortality, almost all organisms. Death is generally applied to whole organisms; the similar process seen in individual components of an organism, such as cells or tissues, is necrosis. Something that is not considered an organism, such as a virus, can be physically destroyed but is not said to die. As of the early 21st century, over 150,000 humans die each day, with ageing being by far the most common cause of death. Many cultures and religions have the idea of an afterlife, and a ...

Intrinsic Value (animal Ethics)
The intrinsic value of a human, or any other sentient animal, is value which originates within itself, the value it confers on itself by desiring its own lived experience as an end in itself. Intrinsic value exists wherever self-valuing beings exist. Because intrinsic value is self-ascribed, all animals have it, unlike instrumental or extrinsic values. Instrumental value is the value that others confer on an animal (or on any other entity) because of its value as a resource (e.g. as property, labour, food, fibre, "ecosystem services") or as a source of emotional, recreational, aesthetic or spiritual gratification. Intrinsic values are conferred from within an animal, and are therefore not directly measurable by economists, while extrinsic values are conferred from outside and can, in principle, be measured econometrically. The phrase "intrinsic value" (often used synonymously with ''inherent value'') has been adopted by animal rights advocates. The Dutch ''Animal Health and Wel ...

Wild-Animal Suffering Research
Wild Animal Initiative (WAI) is a nonprofit organization focused on supporting and producing academic research on improving wild animal welfare. It is one of three "Top Charities" recommended by Animal Charity Evaluators. History WAI was founded in 2019, as a merger of the organizations Utility Farm (founded in 2016 by Abraham Rowe) and Wild-Animal Suffering Research (founded in 2017 by Persis Eskander). Its stated mission is to "understand and improve the lives of wild animals," by studying natural causes of pain and death for animals, such as natural disasters, disease, and starvation. Abraham Rowe was the Executive Director of WAI until 2019, after which Mal Graham became the leader of the organization. In 2022, Graham took the role of Strategy Director, and Cameron Meyer Shorb became the Executive Director. In 2021, WAI received a grant of $3,500,000 from Open Philanthropy to support research on wild animal welfare. In the same year, WAI launched a research fund for hig ...

Wildlife Management
Wildlife management is the management process influencing interactions among and between wildlife, its habitats and people to achieve predefined impacts. It attempts to balance the needs of wildlife with the needs of people using the best available science. Wildlife management can include wildlife conservation, gamekeeping and pest control. Wildlife management draws on disciplines such as mathematics, chemistry, biology, ecology, climatology and geography to gain the best results. Wildlife management aims to halt the loss in the Earth's biodiversity, by taking into consideration ecological principles such as carrying capacity, disturbance and succession, and environmental conditions such as physical geography, pedology and hydrology.Hunter, M. L. (1996). Fundamentals of Conservation Biology. Blackwell Science Inc., Cambridge, Massachusetts., .Groom, M.J., Meffe, G.K. and Carroll, C.R. (2006) Principles of Conservation Biology (3rd ed.).

Threshold Host Density
Threshold host density (NT), in the context of wildlife disease ecology, refers to the concentration of a population of a particular organism as it relates to disease. Specifically, the threshold host density (NT) of a species refers to the minimum concentration of individuals necessary to sustain a given disease within a population. Threshold host density (NT) only applies to density dependent diseases, where there is an "aggregation of risk" to the host in either high host density or low host density patches. When low host density causes an increase in incidence of parasitism or disease, this is known as inverse host density dependence, whereas when incidence of parasitism or disease is elevated in high host density conditions, it is known as direct host density dependence. Host density independent diseases show no correlation between the concentration of a given host population and the incidence of a particular disease. Some examples of host density independent diseases are s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epizootic
In epizoology, an epizootic (from Greek: ''epi-'' upon + ''zoon'' animal) is a disease event in a nonhuman animal population analogous to an epidemic in humans. An epizootic may be restricted to a specific locale (an "outbreak"), general (an "epizootic"), or widespread ("panzootic"). High population density is a major contributing factor to epizootics. Aquaculture is an industry sometimes plagued by disease because of the large number of fish confined to a small area. Defining an epizootic can be subjective; it is based upon the number of new cases in a given animal population, during a given period, and must be judged to be a rate that substantially exceeds what is expected based on recent experience (''i.e.'' a sharp elevation in the incidence rate). Because it is based on what is "expected" or thought normal, a few cases of a very rare disease (like a transmissible spongiform encephalopathy outbreak in a cervid population) might be classified as an "epizootic", while many ca ...

Coronavirus
Coronaviruses are a group of related RNA viruses that cause diseases in mammals and birds. In humans and birds, they cause respiratory tract infections that can range from mild to lethal. Mild illnesses in humans include some cases of the common cold (which is also caused by other viruses, predominantly rhinoviruses), while more lethal varieties can cause SARS, MERS and COVID-19, which is causing the ongoing pandemic. In cows and pigs they cause diarrhea, while in mice they cause hepatitis and encephalomyelitis. Coronaviruses constitute the subfamily ''Orthocoronavirinae'', in the family ''Coronaviridae'', order '' Nidovirales'' and realm '' Riboviria''. They are enveloped viruses with a positive-sense single-stranded RNA genome and a nucleocapsid of helical symmetry. The genome size of coronaviruses ranges from approximately 26 to 32 kilobases, one of the largest among RNA viruses. They have characteristic club-shaped spikes that project from their surface, which in electr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COVID-19 Pandemic
The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The novel virus was first identified in an outbreak in the Chinese city of Wuhan in December 2019. Attempts to contain it there failed, allowing the virus to spread to other areas of Asia and later worldwide. The World Health Organization (WHO) declared the outbreak a public health emergency of international concern on 30 January 2020, and a pandemic on 11 March 2020. As of , the pandemic had caused more than cases and confirmed deaths, making it one of the deadliest in history. COVID-19 symptoms range from undetectable to deadly, but most commonly include fever, dry cough, and fatigue. Severe illness is more likely in elderly patients and those with certain underlying medical conditions. COVID-19 transmits when people breathe in air contaminated by droplets and ...

Bovine Tuberculosis
Bovines ( subfamily Bovinae) comprise a diverse group of 10 genera of medium to large-sized ungulates, including cattle, bison, African buffalo, water buffalos, and the four-horned and spiral-horned antelopes. The evolutionary relationship between the members of the group is still debated, and their classification into loose tribes rather than formal subgroups reflects this uncertainty. General characteristics include cloven hooves and usually at least one of the sexes of a species having true horns. The largest extant bovine is the gaur. In many countries, bovid milk and meat is used as food by humans. Cattle are kept as livestock almost everywhere except in parts of India and Nepal, where they are considered sacred by most Hindus. Bovids are used as draft animals and as riding animals. Small breeds of domestic bovid, such as the Miniature Zebu, are kept as pets. Bovid leather is durable and flexible and is used to produce a wide range of goods including clothing and bags. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animal And Plant Health Inspection Service
The Animal and Plant Health Inspection Service (APHIS) is an agency of the United States Department of Agriculture (USDA) based in Riverdale, Maryland responsible for protecting animal health, animal welfare, and plant health. APHIS is the lead agency for collaboration with other agencies to protect U.S. agriculture from invasive pests and diseases. APHIS's PPQ is the National Plant Protection Organization for the U.S., and the agency's head of veterinary services/veterinary Deputy Administrator is the Chief Veterinary Officer of the United States. History APHIS was created in 1972 by Secretary's Memorandum No. 1769. The origins of the agency predate creation of USDA, to 1854 when the Office of Entomologist, Agricultural Section, U.S. Patent Office was created. It was the first of three agencies that eventually were merged to form APHIS. In 1881, a Cattle Commission was created in the Department of the Treasury that three years later was transferred to USDA. Plant quarantine ...

Oral Rabies Vaccine
The rabies vaccine is a vaccine used to prevent rabies. There are a number of rabies vaccines available that are both safe and effective. They can be used to prevent rabies before, and, for a period of time, after exposure to the rabies virus, which is commonly caused by a dog bite or a bat bite. Doses are usually given by injection into the skin or muscle. After exposure, the vaccination is typically used along with rabies immunoglobulin. It is recommended that those who are at high risk of exposure be vaccinated before potential exposure. Rabies vaccines are effective in humans and other animals, and vaccinating dogs is very effective in preventing the spread of rabies to humans. A long-lasting immunity to the virus develops after a full course of treatment. Rabies vaccines may be used safely by all age groups. About 35 to 45 percent of people develop a brief period of redness and pain at the injection site, and 5 to 15 percent of people may experience fever, headaches, or n ...
