The broad field of cognitive ethology, in which internal mental states are inferred from the behavior they explain, is receiving increased attention nowadays from diverse scientists and philosophers. The nature of the results and how they are presented greatly influence how humans assess their place in the natural world and how they view other animals. The attribution of consciousness and intelligence to other animals suggests that they have moral rights. The results of comparative cognitive ethological analyses and how they are presented may play a large role in defining the domain of morally permissible research, and in the development of research strategies including decisions on feeding and housing, treatment, handling, and what happens to animal subjects when the research is completed. Scientists and philosophers interested in the evolution of behavior and mental continuity can have a significant impact on how others view the world. 相似文献

Though there is a burgeoning interest in applied Buddhist ethics, Buddhist animal research ethics remains an underdeveloped area. In this paper I will explore how some central Buddhist ethical considerations can usefully engage our use of other animals (henceforth, animals) in science. As the scientific use of animals is broad, I will narrow my focus to laboratory science. I will show that, though a Buddhist abolitionism would not be unmotivated, it is possible to reject it. While doing so, it will be important to resist emphasizing elements of Buddhist thought that merely provide reasons to adopt the dominant ethical framework governing laboratory animal research ethics, known as the 3Rs. Though I will suggest how a Buddhist animal research ethics can sometimes permit the use of animals in harmful research, it will also require ethical constraints that resonate with some of the more progressive elements in ‘Western’ bioethics. 相似文献

ABSTRACTThe question of how nonhuman animals think is pervasive in the scientific and popular media, yet there is an apparent lack of concordance between findings from research in animal cognition and how this information emerges in popular discourse. The present study investigated the way people conceive of animal thinking, in order to inform the development of an exhibit on animal minds that will address this issue and foster a deeper connection between people and animals. This two-part, sequential study of perceptions of animal thinking used qualitative interviews of visitors to the New York Hall of Science and Staten Island Zoo to develop a quantitative, online consumer survey of American museum visitors. The results show that American museum visitors vary in their perceptions of animal thinking, but appear to be open to new ideas about how animals might think. Participants' responses to the interviews revealed they could easily recognize survival strategies in wild animals, but had reservations about discussions of empathy, deception, and awareness. In addition, animals kept as pets or companion animals in Western culture were commonly perceived to have higher cognitive capacities for thinking than food or other domestic animals. Participants' responses to the online consumer survey appeared to focus on an overall concept of animal thinking, rather than different cognitive dimensions. Although participants were generally neutral in their responses, demographic analysis revealed participants who had dogs and/or cats, a college education, or watched nature shows were more likely to support the belief that animals can think. Participants who had children at home were less likely to support this belief. Further research is needed to determine how different kinds of thought processes are understood by general audiences and how demographic factors might influence perceptions of animal thinking. 相似文献

In communication animals use a full range of signals: acoustic, visual, chemical, electrical and tactile. The processes involved in how and why animals communicate have long held veritable fascination for scientists. A branch of science concerned with the production of sound and its effects on living organisms is bioacoustics.The main purpose of the present study is to raise and discuss some issues related to the relationship between animals, their sounds and ecology, including presentation of methods of analysis of sound recordings. A better understanding of the relationship between the studied animals will allow for development of a better framework for future research, as well as a better grasp of interactions between different organisms, including humans. The paper discusses the significance of acoustic research in animal ecology and its possible applications in the future. The author also summarizes previous research in the field of sound communication of various animal species.The paper proves that vocalizations of every acoustically communicating animal are threatened by climate change. For marine animals, the source of changes in vocalization abilities is ocean acidification and increased ambient noise, which can affect communication and foraging behavior. For terrestrial animals, changes in precipitation and temperature may result in modifications of the sounds emitted, as well as certain modifications to the auditory system. Together with changes in species distribution due to environmental parameters, cumulatively these factors can cause changes in the entire landscape of acoustics ecosystems. Thanks to acoustic biomonitoring, we can understand how the sounds of entire habitats and acoustic ecosystems will change in response to the changing climate and how it will affect bioacoustics on a global scale. 相似文献

Trapping, handling, and deployment of tracking devices (tagging) are essential aspects of many research and conservation studies of wildlife. However, often these activities place nonhuman animals under considerable physical or psychological distress, which disrupts normal patterns of behavior and may ultimately result in deleterious effects on animal welfare and the validity of research results. Thus, knowledge of how trapping, handling, and tagging alter the behavior of research animals is essential if measures to ameliorate stress-related effects are to be developed and implemented. This article describes how time-stamped location data obtained by global-positioning-system telemetry can be used to retrospectively characterize acute behavioral responses to trapping, handling, and tagging in free-ranging animals used for research. Methods are demonstrated in a case study of the common brushtail possum, a semiarboreal phalangerid marsupial native to Australia. The study discusses possible physiological causes of observed effects and offers general suggestions regarding simple means to reduce trapping-handling-and-tagging-related stress in field studies of vertebrates. 相似文献

The combined efforts of many fields are advancing our understanding of how number is represented. Researchers studying numerical reasoning in adult humans, developing humans and non-human animals are using a suite of behavioral and neurobiological methods to uncover similarities and differences in how each population enumerates and compares quantities to identify the neural substrates of numerical cognition. An important picture emerging from this research is that adult humans share with non-human animals a system for representing number as language-independent mental magnitudes and that this system emerges early in development. 相似文献

The correct regulation of organ size is a fundamental developmental process, the failure of which can compromise organ function and organismal integrity. Consequently, the mechanisms that regulate organ size have been subject to intense research. This research has highlighted four classes of mechanism that are involved in organ size regulation: physiology, plasticity, patterning and physical force. Nevertheless, how these mechanisms are integrated and converge on the cellular process that regulate organ growth is unknown. One group of animals where this integration is beginning to be achieved is in the insects. Here, I review the different mechanisms that regulate organ size in insects, and describe our current understanding of how these mechanisms interact. The genes and hormones involved are remarkably conserved in all animals, so these studies in insects provide a precedent for future research on organ size regulation in mammals. 相似文献

The significance of animals in research cannot be over‐emphasized. The use of animals for research and training in research centres, hospitals and schools is progressively increasing. Advances in biotechnology to improve animal productivity require animal research. Drugs being developed and new interventions or therapies being invented for cure and palliation of all sorts of animal diseases and conditions need to be tested in animals for their safety and efficacy at some stages of their development. Drugs and interventions for human use pass through a similar development process and must be tested pre‐clinically in laboratory animals before clinical trials in humans can be conducted. Therefore, animals are important players in research processes which directly and indirectly benefit animals and humans. However, questions remain as to whether these uses of animals consider the best interests of animals themselves. Various research and training institutions in Tanzania have established some guidelines on animal use, including establishing animal ethics committees. However, most institutions have not established oversight committees. In institutions where there may be guidelines and policies, there are no responsible committees or units to directly oversee if and how these guidelines and policies are enforced; thus, implementation becomes difficult or impossible. This paper endeavours to raise some issues associated with the responsible use of animals in research and training in Tanzania and highlights suggestions for improvement of deficiencies that exist in order to bridge the gap between what ought to be practised and what is practised. 相似文献

Environmental enrichment for laboratory animals has come to be viewed as a potential method for improving animal well-being in addition to its original sense as a paradigm for learning how experience molds the brain. It is suggested that the term housing supplementation better describes the wide range of alterations to laboratory animal housing that has been proposed or investigated. Changes in the environments of animals have important effects on brain structure, physiology, and behavior--including recovery from illness and injury--and on which genes are expressed in various organs. Studies are reviewed that show how the brain and other organs respond to environmental change. These data warrant caution that minor cage supplementation intended for improvement of animal well-being may alter important aspects of an animal's physiology and development in a manner not easily predicted from available research. Thus, various forms of housing supplementation, although utilized or even preferred by the animals, may not enhance laboratory animal well-being and may be detrimental to the research for which the laboratory animals are used. 相似文献

Our interest in animals that 'turn off' dates back at least 300 years. This phenomenon has been reported in most of the major invertebrate phyla and in all vertebrate classes, and has implications for our understanding of a wide range of homeostasis and metabolic control issues. Surprisingly however, it took 20 years of biochemical research before the realization dawned that metabolic depression is the frontline strategy utilized by these animals to survive environmental stress. In this essay, the history of this research is treated in five stages, defined in terms of how the phenomenon now known as metabolic depression was perceived at the time. The two initial stages clearly show that the researchers involved were refractory to the concept of metabolic depression until about 1982 (stage 3). The two stages after 1982 reflect the impact of the acknowledgement of metabolic depression per se and show how research is now being directed towards both the mechanisms involved in, and the cellular targets of metabolic depression. 相似文献

ABSTRACTThis study describes an online public engagement experiment aimed at investigating how acceptance of animal-based research is affected by: (a) the presence of regulations that govern the use of nonhuman animals in laboratories, (b) the invasiveness of procedures, and (c) the use of genetically modified (GM) animals. To meet these aims, participants were asked if they were willing to accept the use of pigs in different scenarios involving agricultural research. Two-thirds of the 681 participants were female and the majority (58%) were young (19–29 years old) with college or university level education (62%). Participants came from 26 different countries, with the United States, Canada, and the United Kingdom being the top three countries represented. Participants who self-identified as being vegetarians, familiar with animal welfare, animal advocates, environmental advocates, and familiar with animal research were significantly more likely to be opposed to animal-based research. Older participants were significantly less likely to oppose animal-based research. Support significantly decreased when animal-based research involved an invasive procedure or GM animals. Support for invasive research significantly increased when regulation was in place, but regulation had less effect on acceptance of GM animal use. Comments provided by participants illustrated different decision-making strategies regarding different types of animal-based research. Given the increasing use of GM animals in research, more effort is required to understand people's concerns regarding this type of animal use and to determine how these concerns should be reflected in policy. 相似文献

Uncontrolled hemorrhage is the most common preventable cause of death for soldiers wounded in combat. In live-tissue trauma training (LTTT), animals (mostly goats and pigs) are used to train physicians and paramedical personnel in how to treat severe traumatic injuries, including severe blood loss. Military personnel insist that such realistic training is necessary and has to date saved countless lives of soldiers. Animal rights groups, however, argue that the practice is inhumane and should be replaced with alternative methods. In this essay, the author explains how and why animals are used for LTTT and in military medical research (MMR), as well as why he feels that the continued use of animals for LTTT and MMR is justified. The author hopes to encourage wider discussion of this topic within the scientific, defense and animal welfare circles, leading to further refinements in the welfare and protection of animals used for these important, though often controversial, purposes. 相似文献

The Freedom of Information Act 2000 prompted the Government to evaluate how public understanding about the use of animals in scientific research can be improved and how animal experimentation is regulated within the UK. This resulted in the publication of anonymous project licence abstracts. Here, the abstracts published between December 2004 and October 2005 have been evaluated, by using a scoring system which takes into account their content and format, in order to assess whether they provide information that will facilitate the increased implementation of reduction, refinement and replacement strategies. The potential impact of freely-available Home Office project licence abstracts on public attitudes to animal testing and on the quality of animal-based research, is also discussed. Although some abstracts scored well, in general, the abstracts were found to be severely lacking in detail about the welfare of experimental animals. Thus, the abstracts tend to present a distorted picture of animal-based research. Many abstracts lack the details which would reveal how the licensing criteria had been met. It is concluded that, in their current form, the project abstracts are not sufficiently informative. A number of recommendations are made, which address this problem. 相似文献

During a disaster, people may make evacuation decisions based on their companion animal’s welfare, therefore exposing themselves, their companion animals, and emergency responders to increased risk for injury or death. The loss and suffering of companion animals in disasters causes deep distress, diminishing people’s capacity to rebuild their lives. This scoping review presents scholarly research studies and reviews relating to people and their companion animals in the context of disasters, with an aim of informing researchers, policymakers, and practitioners and providing direction for future research. Using the Arksey and O’Malley framework, articles in scholarly journals from 2004 to 2014 are discussed. Analysis included 38 articles: 20 research studies, 12 reviews, and 6 editorials. Findings revealed 2 central themes: companion animals as a risk factor to human health and safety and companion animals being “at risk” themselves. An emerging theme was “responsibility”: Who is responsible for companion animals in disasters and how? Understanding the implications of human–nonhuman animal relationships for disaster response and having a broader public consensus on what is owed to animals at times of emergency are important to community preparedness and resilience. 相似文献

Despite the long-standing role that institutional animal care and use committees (IACUCs) have played in reviewing and approving studies at academic institutions, compliance with the Animal Welfare Act (AWA) is not always complete for government natural resource agencies that use free-ranging animals in research and management studies. Even at universities, IACUCs face uncertainties about what activities are covered and about how to judge proposed research on free-ranging animals. One reason for much of the confusion is the AWA vaguely worded exemption for "field studies." In particular, fish are problematic because of the AWA exclusion of poikilothermic animals. However, most university IACUCs review studies on all animals, and the Interagency Research Animal Committee (IRAC) has published the "IRAC Principles," which extend coverage to all vertebrates used by federal researchers. Despite this extended coverage, many scientists working on wild animals continue to view compliance with the AWA with little enthusiasm. IACUCs, IACUC veterinarians, wildlife veterinarians, and fish and wildlife biologists must learn to work together to comply with the law and to protect the privilege of using free-ranging animals in research. 相似文献

Fishes are used in a wide range of scientific studies, from conservation research with potential benefits to the species used to biomedical research with potential human benefits. Fish research can take place in both laboratories and field environments and methods used represent a continuum from non-invasive observations, handling, through to experimental manipulation. While some countries have legislation or guidance regarding the use of fish in research, many do not and there exists a diversity of scientific opinions on the sentience of fish and how we determine welfare. Nevertheless, there is a growing pressure on the scientific community to take more responsibility for the animals they work with through maximising the benefits of their research to humans or animals while minimising welfare or survival costs to their study animals. In this review, we focus primarily on the refinement of common methods used in fish research based on emerging knowledge with the aim of improving the welfare of fish used in scientific studies. We consider the use of anaesthetics and analgesics and how we mark individuals for identification purposes. We highlight the main ethical concerns facing researchers in both laboratory and field environments and identify areas that need urgent future research. We hope that this review will help inform those who wish to refine their ethical practices and stimulate thought among fish researchers for further avenues of refinement. Improved ethics and welfare of fishes will inevitably lead to increased scientific rigour and is in the best interests of both fishes and scientists. 相似文献

Macer D 《Bioethics》1989,3(3):226-235
Macer explores whether it is possible to genetically alter animals to reduce or eliminate their capacity to feel pain, whether it would be ethical to do so, and how we would regard animals that do not feel pain. A possible use for such animals would be as subjects for laboratory research. Among the scientific, philosophical, and ethical uncertainties of pain that Macer considers are: can we define pain? how do we measure pain and anxiety? is pain always related to suffering? what is the minimum level of pain that a being must be able to feel before we reach the conclusion that it should not be used by other beings? are we justified in using beings that do not feel pain when we would not be if they did feel pain and suffer from it? 相似文献

The Keystone Symposium on the Cell Cycle and Development brought together biologists with an interest in how cell cycle control is integrated into the ontogenetic program of multicellular organisms, and showcased research using a wide variety of systems from both animals and plants. A clear indication from the meeting is that this research is changing the conventional wisdom on both cell cycle control and development. 相似文献

Nest building is a taxonomically widespread and diverse trait that allows animals to alter local environments to create optimal conditions for offspring development. However, there is growing evidence that climate change is adversely affecting nest‐building in animals directly, for example via sea‐level rises that flood nests, reduced availability of building materials, and suboptimal sex allocation in species exhibiting temperature‐dependent sex determination. Climate change is also affecting nesting species indirectly, via range shifts into suboptimal nesting areas, reduced quality of nest‐building environments, and changes in interactions with nest predators and parasites. The ability of animals to adapt to sustained and rapid environmental change is crucial for the long‐term persistence of many species. Many animals are known to be capable of adjusting nesting behaviour adaptively across environmental gradients and in line with seasonal changes, and this existing plasticity potentially facilitates adaptation to anthropogenic climate change. However, whilst alterations in nesting phenology, site selection and design may facilitate short‐term adaptations, the ability of nest‐building animals to adapt over longer timescales is likely to be influenced by the heritable basis of such behaviour. We urgently need to understand how the behaviour and ecology of nest‐building in animals is affected by climate change, and particularly how altered patterns of nesting behaviour affect individual fitness and population persistence. We begin our review by summarising how predictable variation in environmental conditions influences nest‐building animals, before highlighting the ecological threats facing nest‐building animals experiencing anthropogenic climate change and examining the potential for changes in nest location and/or design to provide adaptive short‐ and long‐term responses to changing environmental conditions. We end by identifying areas that we believe warrant the most urgent attention for further research. 相似文献

Hundreds of thousands of animals are presented to US veterinarians annually for surgery or for evaluation of painful disease. This large population offers the opportunity for clinical research of both acute and chronic pain syndromes. Although there is growing interest by veterinary clinical specialists to explore the nature of animal pain and how best to treat it, this resource is relatively unknown to the pain research community. Computer-assisted collection of behavioral data has created new opportunities for characterizing the pain experience in animal species for the benefit of both animals and humans. This review describes the current state of veterinary clinical pain studies in dogs and an application of computer-assisted behavioral analysis. 相似文献
