Summary: The study evaluated the effect of moonlight intensity on the feeding and growth of the freshwater opossum shrimp. It found that when not limited by moonlight, the shrimp had higher feeding and growth rates. These findings highlight the importance of predator avoidance for the fitness and metabolic efficiency of the freshwater opossum shrimp.

Summary: This study investigated the inter-sample variance of microplastic concentrations in two urban rivers in Japan and found that the variance was proportional to the mean. A statistical model suggested that microplastics in rivers disperse randomly. A method was established to predict the precision of numerical concentrations based on net sampling repetitions. The findings can help design future field campaigns.

Summary: The study found that microplastics in the Lijiang River are dominated by large-sized flakes and fibers, present in both freshwater and wild fishes. The most abundant polymer types in freshwater were polypropylene-polyethylene copolymer and polyethylene, while polyethylene terephthalate dominated in wild fishes.

Summary: This study investigated the phylogenetic relationships of shrimp genera Ephyrina, Meningodora, and Notostomus. It found that Ephyrina and Notostomus are monophyletic, while Meningodora gains support mainly in morphological trees rather than molecular trees. The evolutionary traits of these genera exhibit differences, with synapomorphies linked to specific adaptations in each clade.

Summary: This study investigated the lipid content of freshwater mysid shrimp populations in 19 lakes in southern Ontario and found variation in lipid content among different lakes. Additionally, the study found that lacustrine characteristics such as Secchi depth can be used as indicators for predicting mysid lipid content.

Summary: This study analyzed the bacterial and eukaryotic microbiota in shrimp aquaculture ponds. The results showed that the bacterial communities in the water were distributed uniformly and relatively stable, while the eukaryotic plankton in the water changed dynamically. The bacterial compositions in the digestive tracts of shrimp differed between ponds and locations.

Summary: High concentrations of microplastic pollution were found in the surface waters of the Vava'u archipelago in Tonga, mainly in the form of small bits of white film. Research efforts on microplastic pollution in the Pacific are lacking compared to other regions.

Summary: In recent years, the capabilities of optical tools and in situ imaging devices have greatly expanded and are revolutionizing the field of plankton research. However, there is still limited research comparing these tools with traditional net-based methods, especially in open-ocean systems.

Summary: Microplastics (MPs) have become the most common type of litter contaminating aquatic environments worldwide, with the potential to harm aquatic organisms and enter the food web. However, the lack of standardized sampling methods and data reporting units makes it difficult to compare studies. This review analyzes the methodologies and characteristics of the commonly used Manta nets for sampling MPs in surface waters and proposes recommendations for improving and standardizing sampling protocols.

Summary: The balance between plankton photosynthesis and community respiration is crucial for the biological carbon pump, but the mechanisms regulating community respiration are still not well understood. This study analyzed data from the Atlantic Ocean and found that depth-weighted rates provided a better understanding of latitudinal patterns and relationships. The study also discovered a significant relationship between community respiration and chlorophyll a concentration, which has potential for predicting community respiration. Additionally, the study found that food web functioning is not solely determined by phytoplankton size structure, indicating the existence of alternative ecosystem states.

Summary: Karankadu mangrove in Southeast coast of India is known for its unique species diversity and richness, providing livelihood to nearby coastal communities. The study assessed seasonal fluctuations of various Physico-chemical factors and recorded the species diversity of zooplankton, phytoplankton, and fish in the mangrove.

Summary: Hologram is an effective method to record the living status of plankton, but the traditional reconstruction method is computationally expensive and noisy. In this paper, we propose an efficient reconstruction network for plankton holograms, which can quickly generate high-quality visual images. Experimental results show that our network is 100 times faster than the traditional numerical method.

Summary: This study reveals the genetic and morphological differences between populations of the cosmopolitan mesopelagic shrimp Systellaspis debilis. While genetic structures remain cohesive across oceans, significant morphological diversification calls for further genomic research to understand the basis of these variations and potential local adaptations.

Summary: This report describes a case of actinomycosis resembling lumpy jaw disease in a gray four-eyed opossum caused by a novel species of Schaalia. The Schaalia infection in the opossum provides new insights into exotic animal bacterial diseases. More knowledge about Schaalia spp. and their pathogenicity will be beneficial for choosing appropriate therapy regimens and improving treatment outcomes in exotic and endangered species.
