Summary: Research has shown that European cuttlefish exhibit unique camouflage responses in the presence of environments with 3D relief and cast shadows. They do not directly use stationary cast shadows as visual depth cues, but rather engage in a two-stage process where they first classify the physical environment before selecting an appropriate camouflage pattern. This categorically rather than continuously variable response allows the animal to select the most suitable camouflage.

Summary: This study reports hirudiniasis caused by Hemiclepsis marginata asiatica in albino red-bellied pacu for the first time in India. Infested fish showed symptoms such as asphyxiation, inability to swim, cloudy eyes, and thick mucus secretion. Histopathological analysis revealed degenerative necrosis, eosinophilic infiltration, and hemorrhages in the affected fish.

Summary: Sexual dimorphism is a major component of morphological variation, but the mechanisms underlying phenotypic differences between sexes of a single species are poorly understood. Our study on Elymnias hypermnestra revealed three genetically distinct populations, with two SNPs near the colour patterning gene WntA significantly associated with the female colour pattern polymorphism. This suggests the repeatability of the evolution of sexual dimorphism in Nymphalidae.

Summary: By studying Heliconius butterflies, it was found that a highly divergent locus containing genes related to locomotion may play a significant role in evolution, potentially leading to species divergence.

Summary: Batesian mimics are harmless species that imitate protected models to deceive predators. The conundrum of why some mimics only loosely resemble their models is addressed in a computer game experiment involving human predators. The findings suggest that even poorly matched mimics can gain protection if the models are aversive, indicating the importance of cost in the evolution of imperfect mimicry.

Summary: The study suggests that information limitation may be a general principle behind imperfect mimicry of complex traits, while interactions between components of mimicry are unlikely to provide a general explanation for imperfect mimicry.

Summary: The study confirmed that the small and densely arranged cluster pattern of leaves has a more significant effect on reducing PM2.5 and PM10 compared to the large and sparsely arranged cluster pattern. Furthermore, architectural surfaces mimicking cluster patterns of leaves, especially folded and porous surfaces, showed better performance in reducing PM2.5 and PM10 levels.

Summary: This study discovered a peptide toxin, MIITX2-Mg1a, in the venom of the Australian giant red bull ant that mimics vertebrate epidermal growth factor. It acts as a potent agonist of the mammalian EGF receptor ErbB1, causing long-lasting hypersensitivity in mice.

Summary: In 2019, a sea life park in Japan experienced a significant number of deaths in aquarium-reared fish, with the dotted gizzard shad being infected by Mycobacterium pseudoshottsii. This is the first isolation of M. pseudoshottsii from aquarium-reared fish, confirmed through bacterial culture and molecular biological examinations.

Summary: Fish behavior can vary consistently within a species and population, showing distinct behavioral types. Comparing the behavior of wild and reared fish provides insights into the ecological and evolutionary consequences of these behavioral types. In this study, we examined the behavioral variation of wild and reared gilthead seabreams, a commercially important species. Our results demonstrate significant repeatability in five major behavior traits and show that reared fish display higher aggression, sociability, and activity levels compared to wild conspecifics. Furthermore, two different behavioral syndromes were identified. This research provides valuable information on the behavior of gilthead seabreams and its implications for fisheries and aquaculture.

Summary: Alpacas, an exotic species in Italy, have become the most widespread camelid species reared in the country. This study assessed the growth parameters of alpacas in the new environment and found that body weight and linear measures were influenced by category and age class. Male alpacas had higher body weight and measurements compared to females, while females had larger rump width. The study also established an equation to estimate alpaca body weight from body measures.

Summary: The study found that MP ingestion in gilthead seabream increased with exposure time, but no MPs were found in the fish gastrointestinal tracts after a detoxification period, indicating no long-term retention of MPs. Exposure to MP enriched diets did not affect fish size or the Fulton's condition index, while carbon and nitrogen isotopic signatures decreased with time.

Summary: The study investigated the growth pattern and physiological status of Pangasius pangasius reared in a pond from July 2021 to September 2021. The growth pattern of P. pangasius in Meghna River was isometric, with positive allometric growth observed in males and negative allometric growth in females. The fish exhibited a healthy population and abundant food sources based on the Fulton's condition factor. The findings also revealed significant differences in certain morphological traits, while blood values showed no significant difference between sexes.

Summary: Certain dietary patterns, such as the traditional Chinese diet, are associated with a lower risk of obesity in the Chinese population, while other patterns, like the Western diet, have inconsistent associations. The heterogeneity in defining dietary patterns contributes to the inconsistency of results.

Summary: Yawn contagion occurs in wild geladas, with individuals responding most strongly to triggering yawns. Factors like yawn duration and mouth-opening degree do not affect contagion likelihood, while group membership and responder sex play a significant role in shaping the phenomenon.
