Unravelling large-scale patterns and drivers of biodiversity in dry rivers.

More than half of the world's rivers dry up periodically, but our understanding of the biological communities in dry riverbeds remains limited. Specifically, the roles of dispersal, environmental filtering and biotic interactions in driving biodiversity in dry rivers are poorly understood. Here, we conduct a large-scale coordinated survey of patterns and drivers of biodiversity in dry riverbeds.

The roles of age, gender, and migration in shaping adolescent student satisfaction within Chilean schools.

This study has a quantitative cross-sectional design that aims to investigate the relationships between gender, age, status (migrant or Chilean-born), educational satisfaction, and overall life satisfaction among adolescent students in 7th and 8th grades of the Chilean educational system. The sample includes 406 students from four municipal public educational centers located in the Santiago district of the Metropolitan Region of Chile, with at least 20% migrant enrollment. The data were analyzed using quantitative methods using the R language, with descriptive analysis, cross-tabulation analysis, and independence tests.

Host interactions of novel species belonging to multiple families infecting bacterial host, WH2.

Bacteroides, the prominent bacteria in the human gut, play a crucial role in degrading complex polysaccharides. Their abundance is influenced by phages belonging to the order. Despite identifying over 600 genomes computationally, only few have been successfully isolated.
