A Comparison of Digestive Strategies for With Different Diet Compositions: Digestive Enzyme Activities, Gut Microbiota, and Metabolites.

Animal gut microbiota play important roles in host immunity, nutrient metabolism, and energy acquisition. The gut microbiota and its metabolic products interact with the host in many different ways, influencing gut homoeostasis and health. is an endemic species which displays special frugivorous behavior, and it has been observed consuming grapes.

Anthropogenic noise and habitat structure shaping dominant frequency of bird sounds along urban gradients.

The shifts of bird song frequencies in urbanized areas provide a unique system to understand avian acoustic responses to urbanization. Using passive acoustic monitoring and automatic bird sound recognition technology, we explored the frequency variations of six common urban bird species and their associations with habitat structures. Our results demonstrated that bird song frequencies in urban areas were significantly higher than those in peri-urban and rural areas.
