Developed by B. F. Skinner, a prominent Harvard psychologist, operant conditioning distinguishes itself from classical conditioning by focusing on learned behaviours rather than reflexive responses. Skinner’s approach emphasises the impact of external environmental factors over internal psychological states in shaping behaviour. This perspective has been particularly influential in fields such as organisational management, where behaviour modification is often applied to improve workplace dynamics. The chapter further explores how operant conditioning can be utilised in management practices by using reinforcements such as pay raises and promotions to motivate employees. This method does not rely on the internal states like beliefs or motivations but rather on modifying the external environment to achieve desired behavioural outcomes. Overall, this chapter not only delves into the historical and theoretical foundations of operant conditioning but also discusses its practical applications in various settings, providing a thorough understanding of both its principles and utility.
There are complexities that hinder the thriving of animals in both natural and artificial environments. This chapter provides a detailed examination of the obstacles animals face and the strategies employed to mitigate these challenges. Barriers to thriving can be classified into two main types: environmental challenges (the multiplier) and internal challenges (the multiplicand). Environmental challenges include adapting to or changing an environment, while internal challenges focus on species-specific and individually specific causes. Significant emphasis is placed on the concept of the ‘Sordid Six’, which represents key environmental obstacles that animals face in captivity. The chapter also discusses mitigation strategies, termed as the divisor, which are essential for reducing the impact of these barriers and enhancing animal welfare.
Animal curation is a vital and evolving discipline that integrates science, policy, and hands-on care to ensure the highest standards of animal welfare. As the role of zoos, aquaria, sanctuaries, and research facilities expands beyond exhibition to conservation and education, the management of animals under human care has become increasingly scientific. This book provides a comprehensive guide to the organisation, policies, and procedures essential for effective animal care programmes. It emphasises evidence-based practices in husbandry, veterinary care, and facility management while prioritising both animal well-being and staff safety. Through detailed chapters and real-world case studies, readers will explore species-specific needs, ethical considerations, and regulatory compliance. Designed for students and professionals in animal science, welfare, and conservation, this book moves beyond basic care, focusing on the concept of ‘thriving’ rather than mere survival. It is an essential resource for shaping the future of animal management and welfare.
This chapter emphasises the importance of understanding the mental states of animals and the profound impact that care settings can have on their overall health. The chapter discusses how a positive internalisation of external variables by animals can significantly enhance their well-being, even in less than ideal conditions. It highlights the role of care technicians in creating environments that not only provide physical safety and resources but also support the psychological needs of the animals. The narrative integrates scientific observations and behavioural studies to underline the necessity of a holistic approach to animal welfare. Moreover, the chapter includes references to various studies and literature that support the methodologies discussed, ensuring that the approaches to animal welfare are grounded in scientific research. This comprehensive overview serves as a guide for improving the standards of animal care through focused psychological and emotional support.
Organisational culture directly affects the implementation of welfare practices, the effectiveness of communication among staff, and the overall morale within the team.

There are various methodologies to assess the well-being and thriving of animals in care. This chapter provides a comprehensive overview of both behavioural and physiological metrics used to evaluate animal welfare. The chapter begins with the specifics of behavioural assessments, discussing the reliability of observers and the use of anecdotal versus ethological observations to gather meaningful data about animal behaviour. Physiological measures are also extensively covered, including routine veterinary examinations, body condition scoring, and assessments of an animal’s quality of life. These measures are crucial for providing a complete picture of an animal’s health and well-being. The chapter emphasises the need for a holistic approach to animal welfare, integrating both observed behaviours and physiological data to ensure that animals are not just surviving but also truly thriving under human care.

There are strategies and methodologies employed to enhance animal welfare in environments that are inherently non-natural. This chapter provides a comprehensive analysis of how artificial settings can be adapted to meet the physiological and psychological needs of animals. It discusses the various aspects of artificial environments, such as the limitations imposed by space and the lack of natural stimuli, and how these can be compensated for through innovative design and management practices. Key topics covered include the design of artificial habitats that mimic natural settings, the importance of providing adequate physical movement, cognitive stimulation, and social interactions within these confines. The chapter also addresses the challenges of creating a stimulating environment that can offer animals a semblance of their natural habitat, focusing on the balance between safety, welfare, and the practical limitations of artificial environments. Overall, the chapter emphasises the necessity of thoughtful and scientifically informed approaches to animal care in artificial settings, aiming to provide animals with opportunities to exhibit natural behaviours and lead fulfilling lives despite the constraints of captivity.
The science of animal care and welfare is centred on a comprehensive exploration into the multifaceted aspects of animal welfare.
The book promises to delve deep into the concept of ‘thriving’ versus merely ‘surviving’, offering a fresh perspective on animal welfare that goes beyond basic needs to encompass physical, psychological, emotional, and social thriving. Halloran introduces the ‘Curatio Fundamentorum’, a foundational approach to animal care that is detailed throughout the book.
This introduction not only outlines the structure of the book but also sets the tone for a detailed discussion on the ethical, scientific, and practical aspects of animal welfare. It is designed to equip caregivers, researchers, and policymakers with the knowledge to improve the lives of animals in their care.
This article centres a poem concerned with the de-extinction of the thylacine (Tasmanian tiger) to make a wider claim for the importance of poetry as a distinct contribution to thinking about de-extinction. While de-extinction is well understood as a scientific practice, it is also a cultural event. It involves communities with distinct histories who are diversely invested in the idea of extinction, which evoke a range of emotions and embodied responses. A poetry of de-extinction is well placed to situate the science within its complex cultural history while evoking the resistance and multiple temporalities of recorded Indigenous experience. In the instance of the efforts towards the de-extinction of the thylacine (Tasmanian tiger), the colonial acts that led to the original extinction were one part of the violence perpetrated against Indigenous peoples and country.
This study describes the reproductive systems of male and female Johngarthia lagostoma, a land crab endemic to South Atlantic oceanic islands, focusing on spermatozoa production and storage. Specimens from Trindade Island (Brazil) were analysed for anatomy, histology, and histochemistry. The male system includes a pair of tubular testes showing different stages of spermatogenesis and spermiogenesis, leading to mature spermatozoa. These move to the anterior vas deferens (AVD), which has proximal and distal portions, the latter containing coenospermic spermatophores surrounded by secretion type I, reactive to proteins and acidic and neutral polysaccharides. The median (MVD) and posterior (PVD) vas deferens produce type II (strongly protein-reactive) and type III (weakly protein-reactive) secretions. Accessory glands between the MVD and PVD produce the same secretions plus a secretion type IV, reactive to neutral polysaccharides. These mix with the spermatophores and other vas deferens secretions, increasing the PVD’s secretion volume, crucial for the initial release of spermatophores into the seminal receptacle. The female reproductive system features voluminous seminal receptacles connected to the ovary, comprising mesodermal and ectodermal regions classified as ventral-type connection. Plugs and sperm packets are absent, with the seminal receptacles filled with free spermatozoa, suggesting dehiscence occurs shortly after sperm transfer. The influence of male and female secretions on this process is suggested, alongside their roles in sperm maintenance and fertilization facilitation.
Myostatin (MSTN), a member of the transforming growth factor-β superfamily, negatively regulates skeletal muscle growth in vertebrates. In teleosts, gene duplication has produced mstn1 and mstn2 paralogues, which often differ in structure and expression. This study compares mstn1 and mstn2 in two high-value mariculture-relevant carangids of the Indo-Pacific region, Trachinotus mookalee and Trachinotus blochii. We report, for the first time, the complete gene structures of mstn1 and mstn2 in T. mookalee (3777 bp from Tm-mstn1 and 2075 bp from Tm-mstn2) and describe their counterparts in T. blochii (3836 bp from Tb-mstn1 and 2147 bp from Tb-mstn2). Notably, mstn1 and mstn2 shared only ∼53% sequence identity within the same species. Interestingly, we noted a CA-repeat tandem sequence in intron 2 (35 bp in Tm-mstn1 and 47 bp in Tb-mstn1), providing a potential microsatellite marker. Promoter analysis suggested more complex transcriptional regulation in T. blochii, with a greater number of transcription factor binding sites (47 vs. 43) and E-box motifs (4 vs. 2). Predicted miRNA binding site revealed both shared (14) and species-specific sites (two sites in Tm-mstn1, and one in Tb-mstn1), indicating differential post-transcriptional regulation. These molecular differences were verified through differential mstn1 expression, with higher mstn1 expression in T. blochii muscle, which might be the reason for the enhanced muscle growth in T. mookalee. The mstn2 expression patterns supported its role in neuroendocrine and reproductive regulation. Overall, this study provides new molecular insights into species-specific growth differences and highlights the functional divergence of mstn genes in marine carangids.
A range of sizes of eight sea urchin species in the Family Echinometridae (Echinostrephus aciculatus, Heliocidaris erythrogramma, Colobocentrotus atratus, Heterocentrotus mamillatus, Heterocentrotus trigonarius, Echinometra mathaei, Echinometra lucunter, and Echinometra vanbrunti) were digitized and their shapes decomposed using elliptical Fourier analysis to quantify shape differences. Coefficients of sines and cosines of harmonics were used in a principal components analysis to show the separation of species. The principal component analysis shows the Echinometridae shape morphospace with the greatest separation of Echinostrephus and Colobocentrotus from other species. Major loadings were related to morphological measurements: height/diameter, lift of the oral surface above the substrate, and position of the ambitus to height. All species showed an increase in height/diameter with size, but only some species showed a correlation of oral lift or position of the ambitus with Fourier coefficients.
