Summary: The study found that dopamine can regulate the agonistic behavior of crayfish, with injections of dopamine aiding smaller animals in winning conflicts while inhibiting larger animals. The inhibitory effect on larger animals is mediated by D1 receptors, while the facilitating effect on smaller animals is mediated by D2 receptors.

Summary: Aggression is a common trait in animals, and social insects provide an excellent model system to study the underlying mechanisms. Biogenic amines play crucial roles in regulating behavior in both social and solitary insects, with aggressive behaviors being mediated by aminergic systems. However, there is still much to learn about the role of biogenic amines in controlling aggression in social insects.

Summary: This study investigated third-party interference and found that interferers derive benefits from winning a fight and the patterns of intervention depend on familiarity. Dyadic fights last longer than triadic fights and interferers engage in non-agonistic social behaviours afterwards.

Summary: This study examined the effect of winning or losing contests on sheltering behavior in crayfish. It found that contest losers significantly increased the time spent inside shelters after the contest, while contest winners did not show significant changes in sheltering behavior.

Summary: The study investigated the sound production of Cyrtograpsus angulatus, a key intertidal decapod in the Southwestern Atlantic Ocean. Male crabs were found to produce high-intensity impulsive sounds during contact and still behavior, displaying body movements involving chelae, legs, and maxillae, with same-size males showing more intense interactions.

Summary: Spinycheek crayfish and signal crayfish, both North American invasive species, compete with native benthic fish for shelter in Europe. In a laboratory study, it was found that these invasive crayfish were able to displace the native stone loach and bullhead, gaining control of the shelter. The presence of crayfish significantly decreased shelter use and caused behavioral changes in the benthic fish.

Summary: Invasive species' interactions can be affected by environmental factors such as nitrate levels, which may influence their foraging efficiency and competitive behaviors. In this study, elevated nitrate levels had varying impacts on two invasive crayfish species, suggesting potential changes in interactions and dynamics in sympatric regions.

Summary: In structured foraging environments with limited, revisitable sites, individuals tend to visit fast-replenishing sites more frequently and are influenced by reward information about unattended sites when making decisions to leave a site.

Summary: Sexual selection pressures play a significant role in driving the evolution of color and behavioral traits in lizards. This study found that winners in agonistic interactions among Achala copper lizards can change the lightness of their skin and display more push-up behaviors. These changes in color and behavior serve as essential signals for contenders to assess their opponent's fighting ability and resolve conflicts without escalating aggression.

Summary: The study found that there are differences in emotional expression between pigs of different levels of aggression, with less aggressive pigs being more susceptible to the emotional impact of victory and defeat, while overall, more aggressive pigs exhibit more negative emotionality at the start of agonistic encounters.

Summary: Research suggests that consumers are more willing to accept service from robots when facing embarrassing situations, as robots reduce the feeling of being judged. However, the level of anthropomorphism in robots affects consumers' perception, with highly human-like robots resulting in more social judgment.

Summary: Research findings showed that the reproductive status of pair-housed male pigs, whether uncastrated, immunocastrated or surgically castrated, did not alter their natural, agonistic and sexual behaviours. This has beneficial effects on the welfare of the animals.

Summary: This article explores the dynamics of listening and emotions in dialogue in multiple-identity conflicts, finding that agonistic listening facilitates the expression of emotions and views, while an attitude of care towards others' stories may help transform antagonistic Others into agonistic ones. However, agonistic listening does not lead to significant perspective change, but entails a temporary suspension of one's own categories to listen to others.

Summary: This study examined the relationship between socioeconomic status (SES) and depressive symptoms and suicidality, and tested the mediating role of subjective social status (SSS). The results showed that both low SES and low SSS were associated with elevated levels of depressive symptoms, suicidal ideation, and suicide attempts. SSS mediated a significant portion of the association between SES and depressive symptoms and suicidality.

Summary: In this study, the researchers used an in vitro analog of operant conditioning (OC) to investigate the effects of OC on the excitability of the inhibitory neuron B4 and its inhibitory connection to the decision-making neuron B51 in a feeding neural circuit. They found that OC decreased the excitability of B4 and weakened its inhibitory connection to B51. These changes were specific and did not affect other neurons critical for feeding behavior. Additionally, the researchers demonstrated that reducing the B4-to-B51 synapse or increasing B51 excitability mediated the OC phenotype more effectively than decreasing B4 excitability alone. Furthermore, they found that combinations of these modifications synergistically enhanced feeding behavior. These results suggest that diverse loci work together to mediate OC and that certain neurons are well suited to work synergistically with plasticity in other loci.
