Summary: This study investigates the decentralized cognition of Temnothorax ants during the emigration process. The researchers developed a model to simulate their behavior and found that considering site population improves the performance of emigration. The study suggests the need for further empirical testing on how ants use site population in nest site selection.

Summary: Through online experiments, this study found that social cues on websites indirectly affect users' likelihood of disclosing private information, and this effect is stronger when users perceive the website as trustworthy. These findings are beneficial for managers and policy makers in safeguarding users' privacy.

Summary: This study investigated the spatial associations among hunting, agriculture, and forestry in Sweden, identifying typical bundles of co-occurring land uses. The research highlighted the importance of integrating wildlife management into land-use planning and pointed out potential conflicts between wildlife and land use in areas where hunting intensity is out of balance with agriculture or forestry.

Summary: Alarm signal propagation in ant colonies provides insights for analyzing information flow in natural systems and other social animals. Researchers developed a method to track alarm spread in a group of harvester ants and used a random forest regression model to assess individual alarm behavior. This approach allows analysis of spatio-temporal patterns in alarm signal propagation and integration of individual and collective alarm response.

Summary: Our study found that there is no subset of specialized pheromone-ignoring foragers in Lasius niger colonies, possibly due to their moderate colony size and strong reliance on individual memories. This raises the question of what defines a scout ant and suggests that a social information-ignoring caste may be less common than expected in ant species.

Summary: Many terrestrial group-hunters cooperate to kill prey but then compete for their share. In contrast, little is known about prey division in group-hunting marine predators, such as striped marlin. A study found that competition for prey access led to an unequal division of prey among the predators, with a few individuals capturing the majority of the fish. Newly arrived groups of marlin had more access to prey, suggesting hunger and motivation may play a role. However, social hierarchies seemed less important in prey division.

Summary: Evaluation relationships play a crucial role in maintaining a cooperative society. This study provides a theoretical analysis of the complex reputation structure that arises when individuals independently evaluate others with errors. The findings offer a novel mathematical basis for studying indirect reciprocity.

Summary: This article discusses the application of RFID technology in item distribution systems, addressing privacy and security issues. A secure RTD system called Ants is proposed, which utilizes cryptography to protect item messages and ensures flexible data access. The system introduces new techniques to carry long crypto-item messages on memory-constrained tags. The security and efficiency of Ants are demonstrated through theoretical analysis and experiments.

Summary: Recent work has highlighted the use of social information by animals, both from their own species and from other species, but the ecological and evolutionary implications of this remain poorly understood. Selective use of social information, including the decision to reject observed behaviors, may have far-reaching consequences and lead to diverse ecological and coevolutionary outcomes between species. This study explores the potential for selective interspecific information use to explain co-occurrences of putative competitors and suggests that these consequences may be more widespread than previously recognized.

Summary: Group hunting is a widespread behavior among animals, but there is still limited knowledge about the mechanisms behind how predators hunt together. The lack of experimental manipulation and difficulties in quantifying the behavior of multiple predators in real-time has hindered research in this area. However, advancements in remote-sensing technologies and expanding the study to include other taxa provide an opportunity to accurately understand how predators hunt together and the benefits of group hunting. This review incorporates ideas from collective behavior and locomotion to make predictions for future researchers and emphasizes the role of computer simulation in conjunction with empirical data collection.

Summary: Eusocial insects, such as ants, exhibit a system of division of labor within their colonies. This provides an opportunity to study the relationship between complex behaviors and their molecular mechanisms. Recent studies have experimentally altered ant behavior, revealing the involvement of neuromodulators and chromatin regulation in these behaviors. In this review, we discuss the current understanding and future directions in studying the relationship between neuromodulators, epigenetics, and social behavior in ants.

Summary: This study found that the Women Physiatry Facebook group can serve as an educational tool across career stages. Early career participants are more likely to use the group for education and networking, while mid- to late-career members are more inclined to use it for learning about certification requirements and finding physiatrists in other areas.

Summary: Many social insects exhibit age polyethism, where young workers stay in the nest and only older workers go out forage. This study investigates if the mechanical demands on the musculoskeletal system prevent young workers from foraging in Atta vollenweideri leaf-cutter ants. The results show that fully matured foragers have significantly higher bite forces and more developed mandible muscles and head capsules compared to freshly eclosed callows of the same size. This suggests that continued biomechanical development may be a key factor underlying age polyethism in situations with substantial mechanical demands.
