A Framework for Assessing the Suitability of Different Species as Companion Animals

Municipal regulations and humane movement policies often restrict or discourage the use of \u27exotic\u27 species as companion animals. However, confusion arises because the term \u27exotic\u27 is used in various ways, and because classifying species as exotic or non-exotic does not satisfactorily distinguish suitable from unsuitable companion animals. Even among commonly kept species, some appear to be much more suitable than others. Instead, decisions about suitable companion animal species need to be based on a number of relevant issues. As ethical criteria, we considered that keeping a companion animal should not jeopardize - and ideally should enhance - its welfare, as well as that of its owner; and that keeping a companion animal should not incur any appreciable harm or risk of harm to the community or the environment. These criteria then served as the basis for identifying and organizing the various concerns that may arise over keeping a species for companionship. Concerns include how the animals are procured and transported, how well their needs can be met in captivity, whether the animal poses any danger to others, and whether the animal might cause environmental damage. These concerns were organized into a checklist of questions that form a basis for assigning species to five proposed categories reflecting their suitability as companion animals. This assessment framework could be used in creating policy or regulations, and to create educational and decision-making tools for pet retailers, animal adoption workers, and potential owners, to help prevent animals from being placed in unsuitable circumstances

Attitudes of Canadian Beef Producers Toward Animal Welfare

Commercial beef production in western Canada involves raising cows and calves on large tracts of grassland, plus grain-based ‘finishing’ of animals in outdoor feedlots. This study used open-ended, semi-structured interviews to explore views on animal welfare of 23 commercial beef producers in this system. Although wary of the term ‘animal welfare’, participants understood the concept to encompass three well-known elements: (i) basic animal health and body condition; (ii) affective states (comfort, contentment, freedom from hunger or thirst); and (iii) the ability to live a ‘natural’ life. Participants attached importance to protecting animals from natural hardships (extreme weather, predators), yet many regarded some degree of natural challenge as acceptable or even positive. Quiet rumination was uniformly regarded as indicating contentment. Avoiding ‘stress’ was seen as a central goal, to be achieved especially by skilful handling and good facilities. Invasive procedures (branding, castration, de-horning) were recognised as painful but were accepted because they were seen as: (i) necessary for regulatory or management reasons; (ii) satisfactory trade-offs to prevent worse welfare problems such as aggression; or (iii) sufficiently short-term to be relatively unimportant. Other issues — including poor facilities, rough or excessive handling, poor nutrition, and failure to protect health — were regarded as more serious welfare concerns. While feeling constrained by low profits, participants saw good welfare as crucial to profitability. Participants uniformly expressed an ethic of care, enjoyment of working with animals, and varying degrees of willingness to sacrifice personal comfort for animal well-being. We argue that animal welfare policy and advocacy are likely to be more successful in engaging producers if they acknowledge and address producers’ views on animal welfare

The ontogeny of nest-building behaviour in Sumatran orang-utans, Pongo abelii

Nest building is an important subsistence behaviour that young great apes must learn to become competent adults. Orang-utans show a remarkable degree of variability and selectivity for a broad range of features in their nest building. However, the details of when different aspects of nest-building skills emerge remain unclear. We used data on 27 immature Sumatran orang-utans and 20 mothers collected over a decade at Suaq Balimbing, Sumatra to investigate when immatures develop their nest-building skills and examine when nest tree species preferences emerge. We found that young orang-utans showed interest in nest building from 6 months of age and begin to construct day nests at around 1 year of age, whereas night nests were not practised until close to the third year of life. Nest-building practice peaked around age 3–4 years and then steadily decreased as immatures approached the age of nutritional independence, around age 8 years. By then, immature orang-utans were competent nest-builders, but their nests differed from adult nests in several aspects, such as fewer multitree nests and additional comfort elements, which seemed to be mastered later in development. All age classes demonstrated stronger selectivity towards tree species used for night nests and immatures eventually had similar preferences to mothers. We conclude that the ontogeny of nest-building behaviour and the selection of nest tree species in Sumatran orang-utans is a multiyear learning process that requires intense practice

Primate Archaeology Evolves

Since its inception, archaeology has traditionally focused exclusively on humans and our direct ancestors. However, recent years have seen archaeological techniques applied to material evidence left behind by non-human animals. Here, we review advances made by the most prominent field investigating past non-human tool use: primate archaeology. This field combines survey of wild primate activity areas with ethological observations, excavations and analyses that allow the reconstruction of past primate behaviour. Because the order Primates includes humans, new insights into the behavioural evolution of apes and monkeys also can be used to better interrogate the record of early tool use in our own, hominin, lineage. This work has recently doubled the set of primate lineages with an excavated archaeological record, adding Old World macaques and New World capuchin monkeys to chimpanzees and humans, and it has shown that tool selection and transport, and discrete site formation, are universal among wild stone-tool-using primates. It has also revealed that wild capuchins regularly break stone tools in a way that can make them difficult to distinguish from simple early hominin tools. Ultimately, this research opens up opportunities for the development of a broader animal archaeology, marking the end of archaeology’s anthropocentric era

Identifying structures, processes, resources and needs of research ethics committees in Egypt

<p>Abstract</p> <p>Background</p> <p>Concerns have been expressed regarding the adequacy of ethics review systems in developing countries. Limited data are available regarding the structural and functional status of Research Ethics Committees (RECs) in the Middle East. The purpose of this study was to survey the existing RECs in Egypt to better understand their functioning status, perceived resource needs, and challenges.</p> <p>Methods</p> <p>We distributed a self-administered survey tool to Egyptian RECs to collect information on the following domains: general characteristics of the REC, membership composition, ethics training, workload, process of ethics review, perceived challenges to effective functioning, and financial and material resources. We used basic descriptive statistics to evaluate the quantitative data.</p> <p>Results</p> <p>We obtained responses from 67% (12/18) of the identified RECs. Most RECs (10/12) have standard operating procedures and many (7/12) have established policies to manage conflicts of interests. The average membership was 10.3 with a range from 7-19. The predominant member type was physicians (69.5% of all of the REC members) with little lay representation (13.7%). Most RECs met at least once/month and the average number of protocols reviewed per meeting was 3.8 with a range from 1-10. Almost three-quarters of the members from all of the 12 RECs indicated they received some formal training in ethics. Regarding resources, roughly half of the RECs have dedicated capital equipment (e.g., meeting room, computers, office furniture, etc); none of the RECs have a formal operating budget. Perceived challenges included the absence of national research ethics guidelines and national standards for RECs and lack of ongoing training of its members in research ethics.</p> <p>Conclusion</p> <p>Our study documents several areas of strengths and areas for improvements in the operations of Egyptian RECs. Regarding strengths, many of the existing RECs meet frequently, have a majority of members with prior training in research ethics, and have written policies. Regarding areas for improvements, many RECs should strive for a more diverse membership and should receive more financial resources and administrative support personnel. We recommend that RECs include more individuals from the community and develop a continuing educational program for its members. Institutional officials should be aware of the resource capacity needs of their RECs.</p

Effects of Blood Products on Inflammatory Response in Endothelial Cells In Vitro

BACKGROUND: Transfusing blood products may induce inflammatory reactions within the vascular compartment potentially leading to a systemic inflammatory response. Experiments were designed to assess the inflammatory potential of different blood products in an endothelial cell-based in vitro model and to compare baseline levels of potentially activating substances in transfusion products. METHODS: The inflammatory response from pre-activated (endotoxin-stimulated) and non-activated endothelial cells as well as neutrophil endothelial transmigration in response to packed red blood cells (PRBC), platelet concentrates (PC) and fresh frozen plasma (FFP) was determined. Baseline inflammatory mediator and lipid concentrations in blood products were evaluated. RESULTS: Following incubation with all blood products, an increased inflammatory mediator release from endothelial cells was observed. Platelet concentrates, and to a lesser extent also FFP, caused the most pronounced response, which was accentuated in already pre-stimulated endothelial cells. Inflammatory response of endothelial cells as well as blood product-induced migration of neutrophils through the endothelium was in good agreement with the lipid content of the according blood product. CONCLUSION: Within the group of different blood transfusion products both PC and FFP have a high inflammatory potential with regard to activation of endothelial cells. Inflammation upon blood product exposure is strongly accentuated when endothelial cells are pre-injured. High lipid contents in the respective blood products goes along with an accentuated inflammatory reaction from endothelial cells
