Summary: Species at their range limits are highly vulnerable to climate change, particularly in the transition zone between temperate and tropical ecosystems. Increasing water temperatures have significant impacts on seagrass ecosystems, including longer stressful seasons, more frequent extreme temperature events, and declining biomass and meadow area. The replacement of temperate species by tropical species is not immediate, indicating the importance of factors such as water clarity, life history, and meadow stability.

Summary: Jellyfish blooms have become a worldwide marine environmental issue, with Aurelia aurita being one of the dominant species in the Bohai and Yellow Seas of China. A complex population-dynamic model was developed to study the population dynamics of A. aurita, showing that temperature is a key factor controlling growth and biomass of the jellyfish in the BYSs.

Summary: The upside-down jellyfish Cassiopea sp. plays a significant role in water column mixing within its shallow natural habitat; it continuously pumps water vertically to create a significant contribution to mixing, resulting in turnover of the water column every 15 minutes at median population density. Additionally, the release of nutrient-rich benthic porewater further emphasizes Cassiopea sp.'s role as an ecosystem engineer in mangrove habitats.

Summary: Understanding the links between species and their environment is crucial for species management. In this study, the authors analyzed capture data of the 'Irukandji' jellyfish to explore patterns of its annual occurrence and abundance in the nearshore waters of the Cairns coast. The results showed that long-term trends, such as rainfall and wind direction, could partially explain the variations in the presence and abundance of the jellyfish.

Summary: The study demonstrates the superiority of the environmental DNA (eDNA) method for estimating aquatic species biomass, but highlights the challenges in clarifying the relationship between eDNA concentration and biomass due to complex water flow and habitat conditions. The research reveals the significant influence of water pH and temperature on eDNA concentration, and suggests considering these environmental factors when estimating biomass using eDNA. The experiment provides valuable insights for accurately estimating aquatic biomass using the eDNA method.

Summary: In recent years, there has been significant progress in the study of planktonic fungi in the marine water column, revealing their diversity and abundance. These fungi are sensitive to environmental gradients and play important roles in biogeochemical cycling and food web dynamics through their saprotrophic and parasitic attributes. However, their function in the open-ocean water column is still poorly understood.

Summary: The uniqueness of soft materials such as hydrogels creates great potential for new soft robots and actuators. Researchers have developed a bioinspired hydrogel jellyfish that is acoustically transparent and exhibits flexible motion, laying the foundation for the construction of next-generation mechanically flexible and acoustically transparent robots.

Summary: In this study, microbiomes cultivated on sorghum were used to assess their performance in deconstructing plant cell walls. Network reconstructions and functional analysis revealed the importance of cellulose-degrading Actinobacteria in differentiating the performance of these microbiomes.

Summary: The recent harmful irregular jellyfish blooms are difficult to explain with macro hydrographic condition changes. To understand the dynamic of jellyfish populations, our focus shifted to the polyp stage and local benthic ecosystems. We monitored the population dynamics of Aurelia coerulea polyps in Jiaozhou Bay and observed their adaptive mechanism in the benthic microhabitat. Our study suggests the importance of considering the local benthic ecosystem and implementing ecosystem-based management strategies to predict and manage problematic jellyfish blooms.

Summary: We propose a model based on active Brownian particles to understand the structure formation of swimming jellyfish. The model addresses the phenomena of counter-current swimming, avoidance of turbulent flow regions, and foraging, incorporating corresponding mechanisms observed in jellyfish swarms reported in the literature. The model's characteristics are tested in three different flow environments.

Summary: This study provides the first report on the distribution of jellyfish abundance, richness, and diversity in the Nuevo Gulf, Argentine Patagonia. The study found that the most abundant species was Eucheilota ventricularis, followed by other Leptothecata species. Abundance and diversity were higher in spring than in summer, influenced by seasonality and environmental variables. The study emphasizes the importance of intensifying sampling throughout the year to increase knowledge about jellyfish distribution patterns in northern Patagonian gulfs.

Summary: Ongoing environmental changes in the Arctic are impacting freshwater ecosystems and their inhabitants, including macroinvertebrates in thaw ponds. Understanding the factors influencing macroinvertebrate abundance is crucial for predicting the effects of ecosystem changes on fish and bird species. In this study, the researchers collected macroinvertebrates from 33 thaw ponds in northern Alaska to examine the spatial and seasonal patterns in abundance. The findings suggest that water temperature and pond type play important roles in determining macroinvertebrate abundance, which could have implications for higher-level predators.
