Lab cognition going wild: Implementing a new portable touchscreen system in vervet monkeys

Rachel A. Harrison et al.

Summary: This study investigates the potential of touchscreen technology for studying cognition in wild vervet monkeys. The researchers found that touchscreen technology can be successfully used in a population of wild primates. Both sanctuary-housed and wild vervet monkeys were able to learn touchscreen tasks, although participation rates were higher in sanctuary-housed monkeys.

There You Are! Automated Detection of Indris' Songs on Features Extracted from Passive Acoustic Recordings

Davide Ravaglia et al.

Summary: We developed an automated classifier based on a convolutional neural network to detect the vocalisations of the singing lemur Indri indri from passive acoustic data. Our network achieved high accuracy and recall values, even for previously unsampled periods and recording sites.

Management of Social Behaviour of Domestic Yaks in Manang, Nepal: An Etho-Ethnographic Study

Theophile Johnson et al.

Summary: This study focuses on the social behavior of yaks in the Annapurna Valley of Nepal and the management practices of herders. The research finds that yaks exhibit cohesive and synchronized behavior, and herders use social relationships among individual animals to maintain group cohesion and effective management.

Acoustic Monitoring of Black-Tufted Marmosets in a Tropical Forest Disturbed by Mining Noise

Esther Bittencourt et al.

Summary: This study investigated the impact of mining noise on the vocalizations of black-tufted marmosets and how they adapt to noisy environments. The study found that areas near the mine have higher background noise levels and more frequent marmoset calls compared to distant areas. The spectral parameters of the calls in the near area also differed from those in the far area. These results suggest that mining noise can affect the acoustic communication of black-tufted marmosets and highlight the need for protective measures.

Opportunities and risks in the use of drones for studying animal behaviour

Lukas Schad et al.

Summary: Drones have become an affordable and highly mobile technology for surveying animal populations and habitats, studying species behavioral ecology, and creating digital terrain models. They provide new possibilities for estimating species abundance, monitoring individual and collective behavior, and studying the composition, spatial organization, and movement of groups.

Incorporating Animal Agency Into Research Design Could Improve Behavioral and Neuroscience Research

Cedric Sueur et al.

Summary: Despite evidence of animals' neural substrates involved in emotions and consciousness, many animals are still restrained in research. These restraints can compromise findings by limiting adaptive behavior expression. Researchers should incorporate animal agency into their research paradigms for improved understanding of brain and behavior mechanisms.

Sequence Order in the Range 1 to 19 by Chimpanzees on a Touchscreen Task: Processing Two-Digit Arabic Numerals

Akiho Muramatsu et al.

Summary: This study aimed to teach the numerical sequence from 1 to 19 in the decimal system to six chimpanzees. Chimpanzees were able to touch adjacent numerals from 1 to 19 and the factors such as range, adjacency, number of stimuli used, and memory load were found to be important for their learning. Comparing with humans, chimpanzees showed relative difficulty in handling two-digit numerals.

Drone Observation for the Quantitative Study of Complex Multilevel Societies

Tamao Maeda et al.

Summary: The application of drone technology has provided a new perspective for understanding multilevel societies, allowing for the capture of spatial structures and movements of large animal groups. Drones have facilitated the observation of spatial positioning patterns and mechanisms of behavioral propagation in multilevel social groups, which differ from those observed in single-level groups. This has contributed to the quantitative definition and assessment of multilevel societies and enhanced our understanding of mechanisms of multiple group aggregation.

GeoDanceHive: An Operational Hive for Honeybees Dances Recording

Sylvain Galopin et al.

Summary: This study aims to provide a new tool for recording honeybees' dances in the field that is practical, fully automated, and does not harm honey production. The GeoDanceHive, an outdoor prototype of a production hive, allows continuous recording and analysis of honeybees' behaviors such as dances. The use of GeoDanceHive can benefit researchers and professional beekeepers, facilitating new research approaches and improving the understanding of landscape ecology of key pollinators.

Information Theory Opens New Dimensions in Experimental Studies of Animal Behaviour and Communication

Zhanna Reznikova

Summary: In the last 40-50 years, ethology has become more quantitative and computational. This review demonstrates that information theory approaches based on Shannon entropy and Kolmogorov complexity can be effective tools for analyzing and comparing animal behaviors. It can also provide ideas for experiments on sophisticated animal communications.

Garrano Horses Perceive Letters of the Alphabet on a Touchscreen System: A Pilot Study

Clara-Lynn Schubert et al.

Summary: This study used a touchscreen system to investigate the visual perception of Garrano horses. The results showed that horses have the ability to discriminate between different letters and that curved and straight-line letters have perceptual similarities. This pilot study provides a new method for horses to freely engage in cognitive tests.

Using Artificial Intelligence to Analyze Non-Human Drawings: A First Step with Orangutan Productions

Benjamin Beltzung et al.

Summary: This study uses deep learning and artificial intelligence to objectively analyze the drawings of an orangutan, revealing seasonal variations and the influence of color and patterning. The importance of this study lies in providing an objective method for analyzing non-human animal drawings.

Yet Another Non-Unique Human Behaviour: Leave-Taking in Wild Chacma Baboons (Papio ursinus)

Lucy Baehren et al.

Summary: This study reviews the limitations of previous research on leave taking in nonhuman animals and introduces a new method to study this behavior. By analyzing videos of chacma baboons, it is found that shifting orientation towards the direction of parting is more likely to occur in social departures compared to nonsocial departures, challenging the notion that leave taking is uniquely human. This evidence suggests a deep evolutionary history of leave taking in nonhuman species and calls for further investigation into its function and presence in other primate species.

A Data-Driven Simulation of the Trophallactic Network and Intranidal Food Flow Dissemination in Ants

Olivier Bles et al.

Summary: This study provides new insights into the behavioral rules underlying the structure of trophallactic networks and food dissemination dynamics within ant colonies. The results show that interindividual heterogeneity and division of labor can influence the dynamics of food flow and the structure of food exchange networks. These findings are important for understanding the evolution of self-organization in social insects.

Hierarchical networks of food exchange in the black garden antLasius niger

Martin Quque et al.

Summary: The study reveals a hierarchical network structure in eusocial insects, not only centralized around foragers but including other intermediaries like domestics. Network resilience, the ratio between global efficiency and centralization, remains stable with colony size but increases in the presence of broods to meet the nutritional needs of larvae.

Aerial drone observations identified a multilevel society in feral horses

Tamao Maeda et al.

Summary: The study utilized drone data to examine the multilevel structure of feral horse society, revealing patterns of unit relationships and positioning that indicate the presence of a hierarchical social organization. This contributes to understanding the functions and mechanisms of multilevel societies and offers insights for future cross-species comparisons and social modeling.
