Abstract:

<p class="normal">Animal ethics has received a lot of attention over the last four decades. Its focus, however, has almost exclusively been on the welfare of captive animals, ignoring the vast majority of animals: those living in the wild. I suggest that this one-sided focus is unwarranted. On the empirical side, I argue that wild animals overwhelmingly outnumber captive animals, and that billions of wild animals are likely to have lives that are even more painful and distressing than those of their captive counterparts. On the normative side, I argue that as long as we have duties of assistance towards humans suffering from natural causes, and we reject anthropocentrism, we also have duties of assistance towards animals suffering in the wild.</p><p class="normal">Article first published online: 22 MARCH 2016</p>

Abstract:

We provide an initial insight into the occurrence and characteristics of animal-visitor interactions (AVIs) involving captive wild animals within zoos and aquaria. Using information provided online via official public websites of modern zoos and aquaria, we found that AVIs were provided by the majority of facilities. Our study revealed that a variety of AVI types were being offered. Globally, petting captive wild animals was the most prevalent AVI type advertised (n = 1241 observations, 43% (534) of facilities) and Mammalia was the most advertised taxonomic class (n = 5142; 53% (2739)). We found certain AVI types that were more commonly offered than predicted. These were opportunities to: (1) Hand feed captive wild animals in Asia, North America and Oceania; (2) ride wild animals in Europe and North America; (3) walk with or swim through wild animal enclosures in Asia; and (4) walk with wild animals in Asia and Europe. Given the global prevalence of AVIs in modern zoos and aquaria, and an apparent lack of animal welfare focused research, we provide recommendations to help effectively balance and manage captive wild animal welfare with other primary interconnected goals.

Abstract:

The keeping of captive animals in zoos and aquariums has long been controversial. Many take freedom to be a crucial part of animal welfare and, on these grounds, criticise all forms of animal captivity as harmful to animal welfare, regardless of their provisions. Here, we analyse what it might mean for freedom to matter to welfare, distinguishing between the role of freedom as an intrinsic good, valued for its own sake and an instrumental good, its value arising from the increased ability to provide other important resources. Too often, this debate is conducted through trading intuitions about what matters for animals. We argue for the need for the collection of comparative welfare data about wild and captive animals in order to settle the issue. Discovering more about the links between freedom and animal welfare will then allow for more empirically informed ethical decisions regarding captive animals.

Abstract:

This ethical discourse specifically deals with dilemmas encountered within zoological institutions, namely for the concept of natural living, and a new term—wilding. It is agreed by some that zoos are not ethically wrong in principle, but there are currently some contradictions and ethical concerns for zoos in practice. Natural living is a complicated concept, facing multiple criticisms. Not all natural behaviours, nor natural environments, are to the benefit of animals in a captive setting, and practical application of the natural living concept has flaws. Expression of natural behaviours does not necessarily indicate positive well-being of an animal. Herein it is suggested that highly-motivated behaviours may be a better term to properly explain behaviours of more significance to captive animals. Wilding refers to extrapolation of the natural living concept to treating an animal as wild, residing in a wild habitat. This definition is intrinsically problematic, as quite literally by definition, captivity is not a wild nor natural environment. Treating a captive animal exactly the same as a wild counterpart is practically impossible for many species in a few ways. This article discusses complexities of natural living versus natural aesthetics as judged by humans, as well as the possibility of innate preference for naturalness within animals. Zoos nobly strive to keep wild animals as natural and undomesticated as possible. Here it is argued that unintended and unavoidable genetic and epigenetic drift favouring adaptations for life in a captive environment may still occur, despite our best efforts to prevent this from occurring. This article further discusses the blurred lines between natural and unnatural behaviours, and the overlaps with more important highly-motivated behaviours, which may be better predictors of positive affective states in captive animals, and thus, better predictors of positive well-being and welfare. Finally, as we are now in the Anthropocene era, it is suggested that human-animal interactions could actually be considered natural in a way, and notwithstanding, be very important to animals that initiate these interactions, especially for “a life worth living”.

Abstract:

ABSTRACTGut microbiota play an important role in maintenance of mammalian metabolism and immune system regulation, and disturbances to this community can have adverse impacts on animal health. To better understand the composition of gut microbiota in marine mammals, fecal bacterial communities of the Australian sea lion (Neophoca cinerea), an endangered pinniped with localized distribution, were examined. A comparison of samples from individuals across 11 wild colonies in South and Western Australia and three Australian captive populations showed five dominant bacterial phyla:Firmicutes,Proteobacteria,Bacteroidetes,Actinobacteria, andFusobacteria. The phylumFirmicuteswas dominant in both wild (76.4% ± 4.73%) and captive animals (61.4% ± 10.8%), whileProteobacteriacontributed more to captive (29.3% ± 11.5%) than to wild (10.6% ± 3.43%) fecal communities. Qualitative differences were observed between fecal communities from wild and captive animals based on principal-coordinate analysis. SIMPER (similarity percentage procedure) analyses indicated that operational taxonomic units (OTU) from the bacterial familiesClostridiaceaeandRuminococcaceaewere more abundant in wild than in captive animals and contributed most to the average dissimilarity between groups (SIMPER contributions of 19.1% and 10.9%, respectively). Differences in the biological environment, the foraging site fidelity, and anthropogenic impacts may provide various opportunities for unique microbial establishment in Australian sea lions. As anthropogenic disturbances to marine mammals are likely to increase, understanding the potential for such disturbances to impact microbial community compositions and subsequently affect animal health will be beneficial for management of these vulnerable species.IMPORTANCEThe Australian sea lion is an endangered species for which there is currently little information regarding disease and microbial ecology. In this work, we present an in-depth study of the fecal microbiota of a large number of Australian sea lions from geographically diverse wild and captive populations. Colony location and captivity were found to influence the gut microbial community compositions of these animals. Our findings significantly extend the baseline knowledge of marine mammal gut microbiome composition and variability.

Abstract:

Optimal animal welfare has been a long-term goal for captive animal institutions. To measure welfare a definition and identification of elements that make up welfare need to be established. Further, a method to measure welfare's elements that can be implemented into staff's daily routine is necessary to establish baseline levels and track changes in welfare. The goal of the proposed captive animal activity tracking system is to allow for the measurement of each element of welfare quickly, while providing information regarding the animal's current state of welfare and how changes to the animal's environment affect welfare. The data show that this system is effective in revealing behavioral patterns and changes in behavior that occurred in response to environmental changes.

Abstract:

The effects of variations in the predictability of appetitive events, such as feeding, have rarely been studied in animals in general or primates in particular. Feeding animals on highly predictable temporal schedules often results in the performance of food anticipatory activity (FAA), characterised by increased arousal and activity and thought to be detrimental to welfare. Temporally unpredictable feeding schedules have been interpreted as resulting in improved welfare. However, if feeding is made unpredictable by preceding it with an unreliable signal, it may result in frustration and aggression. It is suggested here that two distinct but overlapping types of predictability exist. 'Temporal' predictability describes whether an event occurs at fixed or variable intervals, whereas 'signalled' predictability relates to the reliability of a signal preceding the event. This thesis examines the effects of each of these types of predictability in relation to feeding. Welfare was assessed in laboratory-housed common marmosets( Callithrix jacchus) using behavioural measures, which were identified in the context of the routine stressor of human handling and weighing. The signalled and temporal predictability of presentation of a desirable titbit was subsequently experimentally manipulated. It was found that temporally unpredictable presentation of food, preceded by an unreliable signal, was associated with substantially increased stress-related behaviours in this species. If no signal was used, stress increased to a moderate level, but if the food delivery followed a reliable signal there were few behavioural changes compared to control animals. Temporally predictable feeding, without a signal, was associated with lower rates of stress-related behaviour than temporally unpredictable, unsignalled feeding. However, deviations from this temporally predictable schedule, representing delays to feeding, resulted in marked increases in stress. The results were confirmed with a further study, worked around existing feeding routines and using a different primate species, the stump-tailed macaque (Macaca arctoides). Based on these findings it is suggested that the most beneficial schedule for feeding captive primates is a temporally unpredictable one, which appears to buffer animals against the negative effects of delays as well as minimising FAA. Presentation of a reliable signal before food delivery appears to minimise the stress intrinsically associated with a temporally unpredictable routine. These recommendations represent a simple and inexpensive method of improving the welfare of captive primates.

Abstract:

Grooming relationships between adult male chimpanzees are often reciprocal, i.e. individuals receive grooming from those they groom. Grooming may be reciprocated at the same time it is received (mutual grooming), or later within the same grooming session. Alternatively, it can be reciprocated at a much later stage, in another session. An analysis of individual grooming sessions at the dyadic level was used to investigate how chimpanzees reciprocate grooming within these sessions. This study describes the grooming and reciprocation of grooming by male chimpanzees, living in a multi-male, multi-female group at the Edinburgh Zoo, Scotland. A method for the analysis of dyadic grooming relationships was based on the presence or absence of mutual and unilateral grooming in a session, which allows seven types of grooming session to be distinguished. Grooming session was defined empirically, and the duration of the bout criterion interval (BCl) depended on the presence or absence of oestrous females. For comparison, however, the same BCI was used throughout. Without oestrous females, grooming was primarily reciprocated in sessions with mutual grooming and unilateral grooming by both participants. This kind of session proved highly cooperative and each male adjusted the duration of his unilateral grooming to that of mutual grooming, rather than to the duration of unilateral grooming by the other male. Mutual grooming was less important to dyads which had a strong grooming relationship. It is suggested that mutual grooming serves as an indication of the motivation to groom unilaterally. There was no indication that males reciprocated on the basis of TIT-FOR-TAT within these sessions, or between sessions in general. Alternative hypotheses of mutual grooming were only partly confirmed in that some dyads used mutual grooming to reduce the (already very short) time they spent in grooming. However, mutual grooming did not arise from the accidental overlap in the grooming of two partners. In the presence of oestrous females, grooming cooperation between the males broke down, and this was the result of heightened aggression as well as the presence of oestrous females itself. The balance in grooming given and received shifted in the direction of dominants (i.e. dominants received more) under the influence of oestrous females, but in the opposite direction under the influence of aggression. Feeding had no effect on the reciprocity of groormng. There was considerable dyadic variation. Some dyads groomed more when there were oestrous females, others groomed less. Some dyads had proportionally less mutual grooming with increasing numbers of oestrous females, others had more. There were generally no clear patterns of grooming reciprocation over longer time-spans than the session, but the overall degree of reciprocity of a dyad was frequently reached at the end of each day. Tracing the degree of reciprocation over a few weeks indicated that some dyads' grooming was governed by dominance, whereas that of others by cooperation.

Abstract:

AbstractYouTube hosts a vast number of videos featuring zoo animals and humans actively reacting to each other. These videos can be seen as a popular genre of online entertainment, but also as a significant visual artefact of our relations with animals in the age of humans. In this chapter we focus on two viral videos featuring captive orangutans interacting with zoo visitors. The interpretations of ape-human interactions arising from the extensive number of comments posted to the videos are ambivalent in how they see the animals and their assumed capabilities. We argue that the YouTube Zoo could figure as a snapshot of human-animal relations in late modern times: mediating artificial conditions of animals suspended between the wild and the domestic, while offering a screened account of a deeply surprising interaction. The chapter shows the potential of close interactions between humans and animals to destabilise or reinforce the neat divisions between the human and the animal. It also shows the ethical potential of these interactions to either reinforce or question common practices of dealing with wild animals.

Abstract:

Early settlers, pastoralists and hunters, demonstrated an extensive ecological knowledge of the local landscape as of animal behaviour. India rulers used hunts and captive wild animals in the court to underline their bravery, military prowess and valour. The local fascination with shikar (hunting) rubbed off onto British elite, who participated in gruesome farces of urban ‘hunts’, against large wild cats imported in cages from the forests surrounding Bengaluru. Uncaged wildlife were perceived as vermin, leading to an intensive period of targeted kills in the 19^th century. These histories influence our framing of the wild beast as the ‘other’: a being to be valorized in battle, conquered in a hunt, trapped in a cage, butchered for trophies, and exoticized in print, but not capable of co-existing with humans. Solutions are unclear, and would be simplistic to propose. But the need to foster a new ethic of urban conservation appears clear.

Abstract:

Although animals do generally choose what is good for their health, this is not always so. Evolutionary time lags can give rise to a mismatch between the ancestral environment in which choices evolved and the current environment. This happens in wild animals if their environments change, but it is even more likely to happen in domesticated and captive animals as they are often kept in conditions very different from those of their wild ancestors but with a legacy of choice mechanisms more appropriate to the past than the present. They may therefore, like humans, sometimes want things that are bad for their health. As with humans, there is no simple answer to this conflict. However, as ‘wanting’ has in general been selected to deliver what is good for fitness and survival, what animals want usually delivers healthy outcomes.

Abstract:

Genomic instability is a condition that may be associated with carcinogenesis and/or physiological disorders when genetic lesions are not repaired. Besides, wild, captive, and domesticated vertebrates are exposed to xenobiotics, leading to health disorders due to cytogenotoxicity. This chapter provides an overview of tests to assess cytogenotoxicity based on micronuclei (MNi) formation. Bone marrow micronuclei test (BmMNt), peripheral blood erythrocyte micronuclei test (PBMNt), and lymphocyte cytokinesis blocking micronuclei assay (CBMN) are discussed. The most illustrative studies of these techniques applied in different vertebrates of veterinary interest are described. The values of spontaneous basal micronuclei in captive, experimental, and farm animals (rodents, hamsters, pigs, goats, cattle, horses, fish) are summarized. In addition, a flow cytometry technique is presented to reduce the time taken to record MNi and other cellular abnormalities. Flow cytometry is helpful to analyze some indicators of genomic instability, such as cell death processes and stages (necrosis, apoptosis) and to efficiently evaluate some biomarkers of genotoxicity like MNi in BmMNt, PBMNt, and CBMN. The intention is to provide veterinary professionals with techniques to assess and interpret cytogenotoxicity biomarkers to anticipate therapeutic management in animals at risk of carcinogenesis or other degenerative diseases.

Abstract:

Wild boar are dangerous animals that Paleolithic peoples hunted infrequently for the first million years of human-suid contact. Projectile weapons, nets, and the domestication of dogs allowed Natufian hunter-gatherers (12,500–9700 BC) to find in wild boar a reliable source of food. By the Pre-Pottery Neolithic A (9700–8500 BC), human populations had developed close relationships with local wild boar. Intensive hunting or perhaps game management took place at Hallan Çemi in Anatolia, and the introduction of wild boar to Cyprus by at latest 9400 BC indicates the willingness of humans to capture and transport wild boar. At the same time, the presence of sedentary villages and the waste they produced likely attracted wild boar to human habitats. These early relationships between people and suids—game management and commensalism—evolved over the course of the Pre-Pottery Neolithic into full-fledged animal husbandry that, by around 7500 BC, had selected for domestic pigs.

Abstract:

Abstract As the consumption of fossil fuel resources has continuously increased to meet global fuel demands for power generation, atmospheric emissions of greenhouse gases, particularly carbon dioxide (CO2), have rapidly increased over the last century. Increased CO2 emissions have caused serious international concerns about global warming, sea-level rise, and ocean acidification. Although post-combustion carbon capture technology that separates CO2 from flue gas in fossil fuel-fired power plants has contributed to significant migration of atmospheric CO2 emissions, this approach generates considerable amounts of toxic wastewater containing a heavy chemical which is difficult to treat, raises concerns about acute corrosion of metal structures in the facility, and waste of significant amounts of freshwater. In this research, we are particularly interested in reducing the use of freshwater for CO2 capture and generating carbonate minerals, byproducts of CO2 with calcium (Ca2+) or magnesium ions (Mg2+) in ocean water which are useful building blocks for marine animals, such as seashells and coral reefs. In our experimental approach, we attempted to use ocean water with different monoethanolamine (MEA) concentrations and compared the CO2 capturing efficiency with that in DI water. We found that there are considerable benefits of the use of ocean water in CO2 dissolution, showing that a replacement of freshwater with ocean water would be a possible option. In the future, we will further enhance the dissolution of CO2 in ocean water by using nanoparticle catalysts without using MEA, which will be an environmentally friendly method for CO2 capture.

Abstract:

Most quadruped robots capable of running have employed bounding gaits at speeds far below those at which an animal of equal mass would gallop, which is a similar gait. This paper extends the spring-loaded inverted pendulum (SLIP) model to capture the key characteristics of trotting and galloping in biological systems. The objective is to establish a tool that will aid in determining the speed at which bounding or galloping is efficient for robotic systems. The SLIP model includes a linear damper in the legs to model all energy losses in a stride, and in the case of bounding, the body is taken to have an asymmetrical mass distribution. Results indicate that the model exhibits biological characteristics for both trotting and galloping, although duty factors are unrealistically low. Including leg mass in the models to account for additional energy loss does not offer improvement over the use of a linear damper alone.

Abstract:

Vascular structure — a network of convective paths — is a ubiquitous element in multicellular, living systems. The key function of vascular structure in animals and plants is mediation of convective mass transfer over macroscopic distances; this transfer allows an organism to monitor and control the chemical state of its tissues. In our laboratory, we are developing methods to embed and operate microfluidic systems within tissue-like materials in order to capture this function for both biological and non-biological applications. I will present two examples to illustrate our efforts: 1) Capillary beds for the culture of mammalian cells in three-dimensions. In this section, I will discuss the development of methods both to fabricate synthetic capillary beds and to grow them directly out of endothelial cells. I will highlight how simple ideas from continuum mechanics and material science have guided our efforts. 2) Synthetic xylem networks that allow for the transpiration of water at large negative pressures. I will point out the unusual thermodynamic and transport phenomena that are involved in the transpiration process in plants. I will then present our perspectives on the design criteria for systems — synthetic and biological — that mediate this process. Finally, I will describe our experiments with “synthetic trees” in which we have reproduced the main features of transpiration. I will conclude with perspectives on applications and generalizations of both these classes of vascularized materials.

Abstract:

Transport of anthropogenic carbon dioxide in pipelines from capture site to storage site forms an important link in the overall Carbon Capture, Transport and Storage (CCTS) scheme. The thermodynamic properties of CO2 are different from those of other gases such as natural gas that are transported in pipelines. Recent full-scale burst tests from the projects SARCO2 and COOLTRANS indicated significant variations in correction factors necessary to predict the arrest of a running ductile fracture. In addition, CO2 can be a potential hazard to human and animal life and the environment. While consequence distances of natural gas pipelines are well established and documented in standards, this is not the case with CO2. The research focused CO2SAFE-ARREST joint industry project (JIP) aims to (1) investigate the fracture propagation and arrest characteristics of anthropogenic CO2 carrying high strength steel pipelines, and (2) to investigate the dispersion of CO2 following its release into the atmosphere. The participants are DNV GL (Norway) and Energy Pipelines CRC (Australia). The project is funded by the Norwegian CLIMIT and the Commonwealth Government of Australia. The joint investigation commenced in 2016 and will continue to 2019. The experimental part of the project involves two full-scale fracture propagation tests using X65, 610mm (24“) pipe and two 6″ shock tube tests, with all tests filled with a dense phase CO2/N2 mixture. The full-scale tests were made up of 8 pipe lengths each, with nominal wall thicknesses of 13.5 mm and 14.5mm. The dispersion of the carbon dioxide from the full-scale test sections was measured through an array of sensors downwind of the test location. The tests were conducted in 2017/2018 at Spadeadam, UK. Following a short review of the background and outcomes of previous CO2 full-scale burst tests, this paper provides insight on the aims of the overall experimental program along with summary results from the first full-scale fracture propagation test, carried out in September 2017. Two companion papers provide further details on the first test. The first companion paper [IPC2018-78525] discusses the selection of pipe material properties for the test and the detailed fracture propagation test results. The second companion paper [IPC2018-78530] provides information on the dispersion of the CO2 from the first full-scale test, along with numerical modelling of the dispersion.

Abstract:

The Tripletail, Lobotes surinamensis, is a pelagic fish found in tropical and sub-tropical waters of all oceans. Tripletails are often associated with floating debris and make frequent incursions in bays and estuaries where they are targeted by recreational fishermen. In Mississippi waters the species is typically present during the late spring and summer season that also correspond to the period of sexual maturation and spawning (Brown-Peterson and Franks 2001). Tripletail is appreciated as a gamefish but is also prized for its flesh of superior quality. The fast growth rate of juveniles in captivity documented by Franks et al. (2001) and the excellent quality of Tripletail flesh both contribute to the potential of this species for marine aquaculture. In addition, the production of cultured juveniles would be precious to develop a better understanding of the biology, early life history and habitat use of Tripletail larvae and juveniles, a topic largely undocumented to date, through experimental releases and controlled studies. The culture of tripletail thus supports the Tidelands Trust Fund Program through improved conservation of natural resources, potential enhancement of fisheries productivity and potential development of a new economic activity on the Gulf coast producing tripletail via aquaculture. The Objective of this project was to initiate development of methods and techniques needed to spawn captive held tripletail broodfish and raise their offspring to evaluate their growth and development in captivity. In this report we will present the results of studies aiming to develop methods and protocols for captive spawning of tripletail and the first data obtained on the early development of tripletail larvae. A major issue that was encountered with tripletail broodstock development during the project lied in the difficulties associated with identifying the sex of adults caught in the wild and candidates for being incorporated in mating sets for spawning. This issue was addressed during the course of the project by examining the potential of a non-lethal method of hormonal sexing. The results of these preliminary investigations are presented in the third part of this report. All protocols used in the project were determined with the guidance of the Institutional Animal Care and Use Committee (IACUC) of the University of Southern Mississippi (USM IACUC protocol number 10100108).

Abstract:

Highly imperiled Oregon white oak ecosystems are a regional conservation priority of numerous organizations, including Oregon Metro, a regional government serving over one million people in the Portland area. Previously dominant systems in the Pacific Northwest, upland prairie and oak woodlands are now experiencing significant threat, with only 2% remaining in the Willamette Valley in small fragments (Hulse et al. 2002). These fragments are of high conservation value because of the rich biodiversity they support, including rare and endemic species, such as Delphinium leucophaeum (Oregon Department of Agriculture, 2020). Since 2010, Metro scientists and volunteers have collected phenology data on approximately 140 species of forbs and graminoids in regional oak prairie and woodlands. Phenology is the study of life-stage events in plants and animals, such as budbreak and senescence in flowering plants, and widely acknowledged as a sensitive indicator of environmental change (Parmesan 2007). Indeed, shifts in plant phenology have been observed over the last few decades as a result of climate change (Parmesan 2006). In oak systems, these changes have profound implications for plant community composition and diversity, as well as trophic interactions and general ecosystem function (Willis 2008). While the original intent of Metro’s phenology data-collection was to track long-term phenology trends, limitations in data collection methods have made such analysis difficult. Rather, these data are currently used to inform seasonal management decisions on Metro properties, such as when to collect seed for propagation and when to spray herbicide to control invasive species. Metro is now interested in fine-tuning their data-collection methods to better capture long-term phenology trends to guide future conservation strategies. Addressing the regional and global conservation issues of our time will require unprecedented collaboration. Phenology data collected on Metro properties is not only an important asset for Metro’s conservation plan, but holds potential to support broader research on a larger scale. As a leader in urban conservation, Metro is poised to make a meaningful scientific contribution by sharing phenology data with regional and national organizations. Data-sharing will benefit the common goal of conservation and create avenues for collaboration with other scientists and conservation practitioners (Rosemartin 2013). In order to support Metro’s ongoing conservation efforts in Oregon white oak systems, I have implemented a three-part master’s project. Part one of the project examines Metro’s previously collected phenology data, providing descriptive statistics and assessing the strengths and weaknesses of the methods by which the data were collected. Part two makes recommendations for improving future phenology data-collection methods, and includes recommendations for datasharing with regional and national organizations. Part three is a collection of scientific vouchers documenting key plant species in varying phases of phenology for Metro’s teaching herbarium. The purpose of these vouchers is to provide a visual tool for Metro staff and volunteers who rely on plant identification to carry out aspects of their job in plant conservation. Each component of this project addresses specific aspects of Metro’s conservation program, from day-to-day management concerns to long-term scientific inquiry.
