Over the past five decades, a large number of wild animals have been individually identified by various observation systems and/or temporary tracking methods, providing unparalleled insights into their lives over both time and space. However, so far there is no comprehensive record of uniquely individually identified animals nor where their data and metadata are stored, for example photos, physiological and genetic samples, disease screens, information on social relationships.Databases currently do not offer unique identifiers for living, individual wild animals, similar to the permanent ID labelling for deceased museum specimens.To address this problem, we introduce two new concepts: (1) a globally unique animal ID (UAID) available to define uniquely and individually identified animals archived in any database, including metadata archived at the time of publication; and (2) the digital ‘home’ for UAIDs, the Movebank Life History Museum (MoMu), storing and linking metadata, media, communications and other files associated with animals individually identified in the wild. MoMu will ensure that metadata are available for future generations, allowing permanent linkages to information in other databases.MoMu allows researchers to collect and store photos, behavioural records, genome data and/or resightings of UAIDed animals, encompassing information not easily included in structured datasets supported by existing databases. Metadata is uploaded through the Animal Tracker app, the MoMu website, by email from registered users or through an Application Programming Interface (API) from any database. Initially, records can be stored in a temporary folder similar to a field drawer, as naturalists routinely do. Later, researchers and specialists can curate these materials for individual animals, manage the secure sharing of sensitive information and, where appropriate, publish individual life histories with DOIs. The storage of such synthesized lifetime stories of wild animals under a UAID (unique identifier or ‘animal passport’) will support basic science, conservation efforts and public participation.

Taking the 3Rs to a higher level: replacement and reduction of animal testing in life sciences in space research
Human settlements on the Moon, crewed missions to Mars and space tourism will become a reality in the next few decades. Human presence in space, especially for extended periods of time, will therefore steeply increase. However, despite more than 60 years of spaceflight, the mechanisms underlying the effects of the space environment on human physiology are still not fully understood. Animals, ranging in complexity from flies to monkeys, have played a pioneering role in understanding the (patho)physiological outcome of critical environmental factors in space, in particular altered gravity and cosmic radiation. The use of animals in biomedical research is increasingly being criticized because of ethical reasons and limited human relevance. Driven by the 3Rs concept, calling for replacement, reduction and refinement of animal experimentation, major efforts have been focused in the past decades on the development of alternative methods that fully bypass animal testing or so-called new approach methodologies. These new approach methodologies range from simple monolayer cultures of individual primary or stem cells all up to bioprinted 3D organoids and microfluidic chips that recapitulate the complex cellular architecture of organs. Other approaches applied in life sciences in space research contribute to the reduction of animal experimentation. These include methods to mimic space conditions on Earth, such as microgravity and radiation simulators, as well as tools to support the processing, analysis or application of testing results obtained in life sciences in space research, including systems biology, live-cell, high-content and real-time analysis, high-throughput analysis, artificial intelligence and digital twins. The present paper provides an in-depth overview of such methods to replace or reduce animal testing in life sciences in space research.

Munafò, Marcus (Ed.)Throughout the last 2 decades, several scholars observed that present day research into human genes rarely turns toward genes that had not already been extensively investigated in the past. Guided by hypotheses derived from studies of science and innovation, we present here a literature-wide data-driven meta-analysis to identify the specific scientific and organizational contexts that coincided with early-stage research into human genes throughout the past half century. We demonstrate that early-stage research into human genes differs in team size, citation impact, funding mechanisms, and publication outlet, but that generalized insights derived from studies of science and innovation only partially apply to early-stage research into human genes. Further, we demonstrate that, presently, genome biology accounts for most of the initial early-stage research, while subsequent early-stage research can engage other life sciences fields. We therefore anticipate that the specificity of our findings will enable scientists and policymakers to better promote early-stage research into human genes and increase overall innovation within the life sciences.more » « less

Abstract Drones are increasingly popular for collecting behaviour data of group‐living animals, offering inexpensive and minimally disruptive observation methods. Imagery collected by drones can be rapidly analysed using computer vision techniques to extract information, including behaviour classification, habitat analysis and identification of individual animals. While computer vision techniques can rapidly analyse drone‐collected data, the success of these analyses often depends on careful mission planning that considers downstream computational requirements—a critical factor frequently overlooked in current studies.We present a comprehensive summary of research in the growing AI‐driven animal ecology (ADAE) field, which integrates data collection with automated computational analysis focused on aerial imagery for collective animal behaviour studies. We systematically analyse current methodologies, technical challenges and emerging solutions in this field, from drone mission planning to behavioural inference. We illustrate computer vision pipelines that infer behaviour from drone imagery and present the computer vision tasks used for each step. We map specific computational tasks to their ecological applications, providing a framework for future research design.Our analysis reveals AI‐driven animal ecology studies for collective animal behaviour using drone imagery focus on detection and classification computer vision tasks. While convolutional neural networks (CNNs) remain dominant for detection and classification tasks, newer architectures like transformer‐based models and specialized video analysis networks (e.g. X3D, I3D, SlowFast) designed for temporal pattern recognition are gaining traction for pose estimation and behaviour inference. However, reported model accuracy varies widely by computer vision task, species, habitats and evaluation metrics, complicating meaningful comparisons between studies.Based on current trends, we conclude semi‐autonomous drone missions will be increasingly used to study collective animal behaviour. While manual drone operation remains prevalent, autonomous drone manoeuvrers, powered by edge AI, can scale and standardise collective animal behavioural studies while reducing the risk of disturbance and improving data quality. We propose guidelines for AI‐driven animal ecology drone studies adaptable to various computer vision tasks, species and habitats. This approach aims to collect high‐quality behaviour data while minimising disruption to the ecosystem.more » « less

POGIL, or process-oriented guided inquiry learning, is a pedagogical technique created over thirty years ago to enhance student engagement. POGIL is a student-centered approach that improves students’ learning and professional skills. POGIL activities incorporate the classic learning model with recurrent actions of exploration, concept invention, and application to encourage student inquiry. The microbiome represents the total collection of microbes associated with living organisms in distinct locations. The balance of microorganisms at the population level impacts an organism’s health and disease disposition. Enrichment or reduction of specific bacteria, viruses, and fungi in the human population accurately predicts normal or abnormal physiological functions. There is a lack of literature regarding POGIL and microbiome sciences. Thus, this article will elucidate the advantages of developing and integrating microbiome-focused POGIL assignments in institutions of higher learning. The development of additional POGIL activities will improve the understanding of microbiome concepts and experiments designed to explore the composition and functions of the microbiome in various plant and animal ecosystems. Additional educational research on the effects of POGIL activities on student outcomes will boost acceptance of this collaborative learning technique.more » « less

This paper describes the development of the disease ecology tradition of health and medical geography including some key themes and innovations. It first grounds disease ecology in the history of ecology from the natural sciences and the human ecology traditions within the social sciences. These ecological studies of disease developed in response to limitations in the biomedical approach to studying health and disease that developed after germ theory. While the biomedical approach, which mostly focused on human biology, led to groundbreaking advances in medicine for many decades, it had its limits. Disease ecology applications have modern roots in the decades before and after World War II through colonial and tropical medicine as well as work conducted in an array of other sites, including Nazi Germany, the Soviet Union, and the United States when there were large efforts to create infectious diseases maps and conduct ecological analyses of diseases. Hundreds of disease ecology studies have been implemented on diverse disease systems since World War II. The field progressively broadened in scope, especially during the 1990s and beyond, with several innovations including the application of political ecology approaches to the study of health and disease. Two other recent innovations are summarized through case studies: disease ecology approaches in health intervention research and applications of theory and methods from landscape genetics. The first case study highlights the ecological and geographic heterogeneity associated with the health impacts of drinking‐water tubewell interventions in rural Bangladesh. The paper also considers ‘landscape genetics’ approaches via a case study about influenza that uses modern genetic and spatial tools along with an ecological approach; it describes how the evolution of the virus is related to human‐environment‐animal interactions. The paper concludes by outlining promising future directions for disease ecology, emphasizing the field's ongoing incorporation of new theories and methods.more » « less
