Summary: Punishment is used in human and animal societies to respond to cheating. This study compares punishment in reef-dwelling cleaner wrasses and humans, and finds that humans are more sensitive to the transgressor's choice while punishing compared to the cleaner wrasses. The results shed light on the cognitive mechanisms that shape punishment decisions and the importance of choice in punishment.

Summary: Individuals engaged in cooperative or mutualistic interactions can benefit from adjusting their strategic behaviour according to the bargaining positions of their partners, but the cognitive challenges involved in this assessment and the constraints they may pose for strategic behaviour are currently poorly understood.

Summary: Ocean acidification affects fish behaviour by disrupting GABAergic neurotransmission, and this study investigates the role of GABAergic modulation in cleaning behaviour between Labroides dimidiatus and its clients. The results show that exposure to ocean acidification conditions decreases the motivation to advertise cleaning services. The GABAergic antagonist gabazine can recover the CO2-induced behavioural alterations to control levels, while muscimol treatment produces similar behavioural alterations as CO2 exposure.

Summary: This study provides new insights into the reproduction and early ontogeny of the Bluestreak cleaner wrasse in captivity, revealing its spawning frequency, hatching rate, and larval development process, as well as determining the optimal rearing conditions. These findings are of great importance for further research on mass-scale production of juvenile Bluestreak cleaner wrasse.

Summary: The study revealed the impact of partner choice options and other key partner traits on the cooperation levels between cleaner fish and client reef fishes. The cheating behavior of cleaner fish is influenced by multiple factors, similar to the way female mate choice is influenced by various factors in sexual selection theory.

Summary: The protective mimicry between the bluestreak cleaner wrasse and the false cleanerfish does not always decrease the predation risk, suggesting that the mimicry may have evolved primarily as aggressive mimicry.

Summary: The effects of UV-A radiation on the growth and physiological and biochemical traits of green leaf basil were investigated. UV-A did not have any negative effects on plant growth and photosynthetic functions, even at high doses. It also enhanced thylakoid processes and increased the pool of xanthophyll cycle pigments, contributing to the plant's response to the light environment.

Summary: The study found that the barber goby Elacatinus figaro is less reliant on cleaning interactions for food than other cleaning goby species. Its diet and abundance did not correspond to the availability of ectoparasites and/or clients, indicating a high feeding and behavioral plasticity in marginal reefs.

Summary: This study investigated the molecular mechanisms in the brain regions of cleaner wrasse and potential client fish during their interactions. Using transcriptomics, the researchers found that the transcriptional response in both species was mainly regulated in the Hindbrain and Forebrain regions. The cleaner wrasse exhibited immediate early gene alteration, involvement of dopaminergic and glutamatergic pathways, and expression of neurohormones and steroids. On the other hand, the client fish showed fewer molecular alterations, mostly involving pituitary hormone responses.

Summary: NH3 absorption cross-sections in hot gas environments were experimentally measured at different temperatures, allowing for quantitative in situ detection of NH3 in various hot gas environments. The absorption cross-section decreases at higher temperatures, enabling nonintrusive quantification of NH3 in different environments with detection limits varying from below 10 ppm to around 200 ppm. The quantitative measurement was successfully applied to an experimental investigation of NH3 combustion.

Summary: Based on principal component analysis (PCA), Aellen et al. (2022) argue against the existence of a general cognitive ability (GCA) factor in wild-caught cleaner fish. Instead, they find three equally important factors, with the first showing a mix of positive and negative loadings. Reanalyzing the data using unit-weighted estimation reveals a GCA factor with all positive loadings, accounting for 29.9% of the variance. These findings suggest that more extensive sampling could reduce sample specificity effects and lead to the discovery of a GCA factor. Additionally, the proportion of variance associated with the GCA factor in the wild-caught cleaner fish is similar to that found in a meta-analysis of 12 other animal taxa, supporting adaptationist theories of GCA.

Summary: In this study, the effects of replacing Mo with Cr atoms on the lattice structure, energy bands, and light absorption properties of 2D monolayer MoSi2N4 were systematically investigated using density functional theory (DFT) and the Vienna Ab initio Simulation Package (VASP). The results showed that Cr atoms can effectively modulate the electron accumulation and light absorption properties of the material, providing a strategy for designing new 2D materials with high absorption properties.

Summary: In this study, the absorption cross sections of carbon disulfide were measured by reducing its conversion to carbon sulfide. By controlling experimental conditions, including gas flow rate, ultraviolet light intensity, and duration of illumination, the researchers were able to calculate the absorption cross sections of carbon disulfide at room temperature and atmospheric pressure. The maximum absorption cross section of carbon disulfide was found to be 4.5 x 10(-16) cm(2)/molecule at a wavelength of 198.10 nm.

Summary: In this study, a new combination of Raman and ultraviolet and visible (UV/Vis) absorption spectroelectrochemistry is proposed, which allows obtaining electronic, vibrational, and electrochemical information simultaneously. This technique has shown to be useful and versatile in various fields of chemistry. Two different systems were used to demonstrate its advantages and capabilities, showing that it is a compact and easy-to-use tool for future applications.

Summary: Adding rodlike nano-ZnO particles to asphalt improves its aging resistance and modifies its properties. The experiment demonstrates that rodlike nano-ZnO can increase the softening point, reduce penetration, and enhance the complex shear modulus of asphalt composites.

Summary: The study found that cleaner wrasse in the Indo-Pacific region are infected by a variety of parasites, including species that are rarely found in other fish. This suggests that some parasite species may exploit cleaning symbiosis to complete their life cycles.

Summary: The study reveals that chemical cues from dead corals can increase the infection rate of micropredatory parasites in juvenile fish, but not in adults. Juvenile fish also have a higher mortality rate after infection, emphasizing the importance of including parasitism in ecological studies of global environmental change.

Summary: The study explored the variability in traits of cleaner fishes and their correlation with historical, environmental, ecological and geographical drivers at global reefs. Results showed that facultative cleaners exhibited high trait variability, while dedicated cleaners had low trait variability. Cleaner species richness was higher in the Indo-Pacific and Caribbean provinces, but the relative richness and standardized abundance were higher in the Atlantic and Eastern Pacific. Isolation and environmental factors influenced the relative richness of both facultative and dedicated cleaners. Local species richness and abundance of potential clients were also found to have a strong relationship with cleaner fish abundance.

Summary: Cleaning symbiosis is crucial for maintaining healthy biological communities in tropical marine ecosystems, but it may also facilitate the transmission of parasites. Experimental evidence shows that the bluestreak cleaner wrasse, L. dimidiatus, is susceptible to some parasites but exhibits resistance and can temporarily transport parasites.

Summary: Cleaner fish have complex effects on benthic community, with the abundance of fish on coral reefs being differently affected by grazer functional group. The study suggests that benthic communities have resilience to the loss of cleaners, but the absence of cleaners has negative ramifications for fish populations and physiology.
