Summary: Fisheries research has been a source of excitement and discovery for me, rather than just a job. From finding new fish species to understanding their longevity and the impact of atmospheric chemicals on their survival, every day has been full of surprises. There are now better opportunities to understand the dynamics of fish populations, especially as climate change threatens their habitats. It is crucial to have young, team-oriented individuals who can pursue these new opportunities.

Summary: Social insects provide valuable models for studying the relationship between brain size and behavioral variability. In the jatai stingless bee, division of labor is determined by both age and body size differences among workers. The brain size differences between jatai soldiers correspond to their specialized defense tasks, illustrating functional neuroplasticity.

Summary: Wildfires have a significant impact on the composition and structure of animal communities, particularly those associated with vegetation and soil, such as bees and ants. This study found that both ant and bee communities showed increased taxonomic richness after fire, but the functional composition of the communities changed. The effects of fire on ants varied depending on the time since the fire.

Summary: With the development of globalization, distributed manufacturing has become a main mode of manufacturing. This paper addresses a distributed heterogeneous no-wait flowshop scheduling problem (DHNWFSP) and proposes a discrete artificial bee colony algorithm (DABC) to effectively solve it, considering the heterogeneity between factories in distributed flow-shop scheduling for the first time. The proposed DABC achieves the highest-quality solutions in comparison with state-of-art algorithms, as shown by numerical experiments for small and large-scale problems.

Summary: This research investigates the potential impact of hydrogels on honey bees and proposes modifications to reduce the risk. The study confirms the presence of fipronil in aerosol form and identifies the maximum distance at which the aerosols fall to the ground under specific wind conditions. It is found that even bee hives upwind and several hundreds of meters away from the baited area can be contaminated by the aerosols. However, there is no significant mortality observed in bee hives due to either free-falling bait or relocation of bee hives beyond the treatment area.

Summary: The biology of burrowing crayfishes is not well understood due to their underground habitat. We conducted a 24-hour video recording survey on the Little Brown Mudbug and discovered that they exhibit sit-and-wait predatory behavior and consume both animals and plants. This study provides new insights into the foraging behavior and trophic role of burrowing crayfishes.

Summary: Despite advances in genomic data, a solid framework for genome-based species delineation is still lacking. This is particularly critical for phylogeographically structured organisms, where allopatric populations show similar divergence patterns as species. In this study, we assessed the species limits and phylogeography of Zodarion alacre, a spider species widely distributed across the Iberian Peninsula. Using genome-wide data, we identified four distinct lineages with no admixture and validated these results with additional evidence. Despite ecological differentiation, the lineages showed no clear morphological differentiation, indicating incomplete speciation. Phylogenomic networks revealed substantial gene flow between lineages, and phylogeographic methods highlighted isolation by distance and range expansion. Our findings shed light on the diversification of Zodarion and emphasize the importance of considering gene flow evidence in species boundaries.

Summary: This paper introduces three multi-objective electric vehicle routing problems that consider different charging strategies and electric vehicle charger types while optimizing five conflicting objectives. A new hierarchical approach consisting of Hybrid Ant Colony Optimization (HACO) and Artificial Bee Colony Algorithm (ABCA) is developed to solve these problems. The proposed approach is examined on test-based instances and achieves the best new results in most cases.

Summary: The study revealed that variation in species richness and composition across tropical mountains is closely associated with elevational gradients, which are more influenced by climatic changes than latitudinal gradients. Despite having narrow elevational ranges, the biogeographical effects of tropical mountains continue to drive high diversity.

Summary: Species have different preferences for substrate and illumination in their habitat. E. nostras prefers shade and medium sand grains, while M. formicarius chooses illuminated areas and the same sand size. During interactions, E. nostras prioritizes abiotic factors, while M. formicarius avoids interactions and builds pits in less suitable conditions. These findings have implications for their natural habitat and life traits.

Summary: The study found that ant communities vary among sites on Barro Colorado Island in Panama, but aboveground ant community composition does not change between seasons. Variation in ant composition between sites does not predict seed removal patterns. Ants that remove seeds do not differ morphologically from the broader ant community.

Summary: Social insects, such as stingless bees, employ various defensive behaviors at night to protect the nest and each other, including nightly nest closing and night guarding. The study observed significant differences in behavior among colonies, with more guards seen at the entrances of open nests. Preliminary evidence suggests that a kairomone released by kleptoparasites may influence nest closing behavior.

Summary: The study found that in eusocial stingless bees, soldiers have higher visual neural investment when performing visually demanding defense tasks, but this difference disappears as tasks change. Neural investment is otherwise similar across different task groups. Despite having larger task repertoires, soldiers have relatively smaller brain sizes compared to other workers.

Summary: The study found that the relationship between the spokesperson and the science story influences how people perceive and react to online science media. When a scientist presents their own research, they are perceived as more trustworthy and competent compared to a third-party presenter or no-spokesperson stimuli. This personal connection also humanizes the research in the eyes of the viewers.

Summary: Plants often rely on passive or active agents to find suitable microhabitats for seed germination. Ants frequently move Zanthoxylum ekmanii seeds, but the effectiveness of ant-mediated seed removal depends on the species involved, the distance moved, and the deposition site. Ectatomma ruidum ants can move seeds to suitable deposition sites, but the seeds may experience damage from the ants.

Summary: This study investigates the mechanisms by which harvester ants cope with desiccating environmental conditions. The results show that larger-bodied ants have a higher desiccation resistance, and the abundance of cuticular hydrocarbon profiles is positively related to desiccation resistance. These findings contribute to understanding the physiological mechanisms of desiccation resistance in insects.

Summary: Associating morphological features with ecological traits is crucial for understanding the relationship between organisms and their environmental roles. However, functional trait data without natural history information provide an incomplete understanding of an organism's ecological role. In this study, we found that body size, relative eye position, and scape length were informative for predicting diet/trophic position in ant communities, albeit with relatively weak predictive values.
