Behavioural research in zoos is commonplace and is used in the diagnosis and treatment of potential husbandry and management challenges. Robust methods that allow valid data collection and analysis constitute an evidence-based approach to animal care. Understanding behaviour is essential to improving animal management, and behavioural research is therefore popular, with a wide choice of behavioural methodologies and theories available. This review outlines ten methodological approaches, concepts or theories essential to zoo science that are based around behavioural observation. This list is not exhaustive but aims to define and describe key areas of consideration when planning and implementing a zoo-based behavioural project. We discuss the application of well-established methods (the construction of ethograms, use of time–activity patterns and measurement of space/enclosure use) as well as evaluating newer or less-widely applied analytical techniques, such as behavioural diversity indices, social networks analysis and Qualitative Behavioural Assessment. We also consider the importance of fundamental research methods, the application of pure science to understand and interpret zoo animal behaviour (with a review of a Tinbergian approach) and consideration of meta-analyses. The integration of observational techniques into experiments that aim to identify the cause and effect of behavioural performance is then explored, and we examine the assimilation of behavioural methods used in studies of environmental enrichment. By systematically studying animal behaviour, we can attempt to understand the welfare of individual animals in captivity, and here we present an example of our reviewed approaches to this area of zoo science. Combining multiple methodologies can lead to a greater understanding of behaviour and welfare, creating robust research, progressing husbandry and advancing conservation strategies. Collaborations between zoological collections and academic researchers (e.g., in Higher Education Institutions) can further refine and enhance the validity of research and husbandry practice alike.
Behaviour is the observable response of individual human or non-human animals to endogenous or exogenous signals [1]. Endogenous stimuli originate internally as part of the animal’s physiology (e.g., hormonal changes), and exogenous stimuli are external, originating from the wider environment [2]. Complex and basic animals alike survive by continuously, and often instinctively, reacting to stimuli, culminating in behavioural expression with adaptive value [1]. This alters the phenotype of (sub)species, leading to individual differences within species and populations [3]. Behaviour includes the large-scale actions of an animal, such as locomotion, feeding and social activity, but also the gait, posture, gestures, facial expressions, vocalisations and other communicative signals an animal may express [1, 4]. The fact that behaviour is obvious, measurable and can be manipulated makes it one of the biological scientist’s most useful tools for investigating the natural world [1]. Animal behaviour studies typically, both historically [5] and currently [6], comprise a large proportion of zoo and aquarium (hereafter “zoo”) research output, potentially because of both the ease of recording such data and the many ways behavioural observations can be integrated into wider research projects.
Badger Behaviour, Conservation & Rehabilitation
In zoos, behaviour is essential to inform an evidence-based approach [7] to animal husbandry and population management. Determining how to care for captive animals using research to inform decision-making is essential if we are to allow captive wild animals to thrive rather than merely survive in the zoo [8, 9, 10]. By first observing behaviour, and secondly attempting to interpret meaning, we can compare captive and wild behaviour, understand animal behavioural needs, cognition and preferences, increase reproductive success, change enclosures to allow a greater repertoire of behavioural expression, understand what aspects of enclosure provision and wider husbandry are important to the animal and minimise the influence of captive stressors [10, 11, 12]. The remit of zoo research has expanded in scope and type over the years, but behaviour remains a consistent focus and methodological application [6, 13].
Animal behaviour (in pure and applied contexts) is commonly taught as a stand-alone degree in the university sector (from Foundation to Masters’ degree) as well as part of broader degree topics, such as Psychology, Conservation Biology or Animal Science. Likewise, a proliferation in zoo-specific qualifications (e.g., Zoo Biology, Zoo Conservation Biology and Zoo Animal Welfare), from college diplomas to postgraduate degrees, is noted [14], reflecting a student-led demand to study zoo animal management as a core topic of further and higher education. Students and those seeking employment in the animal management or conservation industries need to understand and be able to apply behavioural methodologies and key theories.
All behaviour-based projects, regardless of the specific methodology, start with a broad research question. Planning of the study radiates from this central point with some almost universal considerations common to nearly all research (Figure 1). Any aims need to be defined to guide the planning of methods and provide a rationale for the research. For most quantitative and some qualitative approaches, hypotheses will be constructed to direct what data are collected, how data are collected and the data analysis process. For zoo-based behavioural research, questions often arise based on certain species, commonly due to a lack of evidence for the care of that species in the zoo or a desire to know more about the species’ responses to husbandry and management. For basic science questions, species selection may be based on the most appropriate candidate for answering that specific question (for example, when the aim of the study is wide, or one is conducting an over-arching investigation of fundamental principles, such as behavioural plasticity or adaptation to captivity).
Emerging Technologies For Behavioral Research In Changing Environments: Trends In Ecology & Evolution
Understanding the natural ecology of the species is important when considering what to measure and when; therefore, an ethogram is required to define behaviours. The focus must then shift to considering behavioural sampling (what, when, how and whom to collect behavioural data from). Reviewing available information on temporal or seasonal activity patterns will help with deciding when/where to place trail cameras (or similar technology for remote monitoring) or observe in person to provide the best chance of capturing maximal behavioural data, or providing opportunities for behavioural manipulation (such as enrichment) to maximise the subject’s engagement. The species’ natural history and behavioural ecology will also influence the timeframe of data collection and how long needs to be spent recording behaviour, which also needs to account for the zoo’s hours of opening (i.e., access to the sample population and/or placement and access of remote monitoring equipment). Answering these questions will ultimately allow specific behavioural techniques to be selected and applied for successful data collection. Which behavioural methodological approach or theory is most helpful for which specific question?
The aims of this paper are to provide an explanation and description of important methodological approaches and key scientific concepts and theories to the study of animal behaviour in the zoo, to guide the end stages of methodological planning and the collection of valid and relevant data. We explain key terms and methodological principles and direct the reader to useful sources of further information should this method be most suited to the development of their behavioural research project. This paper is primarily aimed at students and new-to-the-zoo researchers but may also be of help to more established scientists looking to diversify their application of behavioural techniques. Given the lack of repeatability of methods and reproducibility of results noted in reviews of published scientific studies [15, 16], this paper aims to introduce the fundamentals of ten behavioural methods or concepts applicable to zoo studies so that any researcher, regardless of level, can commence data collection with confidence in the validity and robustness of their chosen approach.
In this section, we provide definitions and explanations of ten behavioural methods (ethograms, time–activity budgets, space/enclosure usage calculations, behavioural diversity indices, social network analysis, qualitative behavioural assessment, meta-analyses), concepts (experimental studies and repeated measures, assessing enrichment using behavioural data) and theories (Tinbergen’s Four Questions) to help the zoo researcher decide on their best approach when developing a research design for observation data collection. As with all scientific research, it is essential to have
