Tropical freshwater environments, like rivers, are important reservoirs of microbial life. This study employed metagenomic sequencing to survey prokaryotic microbiota in the Solimões, Purus, and Urucu Rivers of the Amazon Basin in Brazil. We report a rich and diverse microbial community.

Viruses are the most abundant biological entities on Earth, and they play a critical role in the environment and biosphere where they regulate microbial populations and contribute to nutrient cycling. Environmental viruses have been the most studied in the ocean, but viral investigations have now spread to other environments. Here, viral communities were characterized in four cave pools in Carlsbad Caverns National Park to test the hypotheses that (i) viral abundance is ten-fold higher than prokaryotic cell abundance in cavern pools, (ii) cavern pools contain novel viral sequences, and (iii) viral communities in pools from developed portions of the cave are distinct from those of pools in undeveloped parts of the same cave.

The gut microbiota, which includes prokaryotes, archaea, and eukaryotes like yeasts, some protozoa, and fungi, significantly impact fish by affecting digestion, metabolism, and the immune system. In this research, we combine various tasks carried out by various bacteria in the gut of fish. This study also examines the gut microbiome composition of marine and freshwater fish, identifying important bacterial species linked to different biological functions.

Background: Different species of sea cucumbers in various regions have diverse preferred habitats and feeding habits. However, detailed research on the correlation between food selection and habitat preference of sea cucumbers, as well as their adaptive adjustments to specific habitat types, is still lacking.
Methods: A field study was carried out to explore the relationship between food selection and habitat preference, as well as the adaptation process, of the tropical sea cucumber Stichopus chloronotus, which has specific food preferences.

Background: Inter-cropping is a reasonable planting pattern between different plants. Inter-cropping of with is a relatively mature planting pattern in China, which has been applied to improve soil ecological environment and reduce the occurrence of pests and diseases in China. However, there is currently limited knowledge on the response of soil microbial communities to this practice.
