Article Abstract
Biodiversity and functional traits are increasingly recognized as pivotal factors in regulating ecosystem functioning and stability. However, the patterns and processes of multidimensional biodiversity and functional traits along environmental gradients remain insufficiently understood. In this study, we examined taxonomic, phylogenetic, and functional diversity across multiple trophic levels in 38 alpine grassland sites along a precipitation gradient on the Qinghai-Tibet Plateau. Our findings reveal asynchronous responses of taxonomic, phylogenetic, and functional diversity metrics, as well as functional traits across trophic levels, to variations in precipitation. Soil microbial diversity and functional traits exhibited stronger responses to precipitation changes compared to plant communities, with a tighter coupling observed between microbial diversity and microbial functional traits. Climate and soil properties jointly regulated diversity and functional trait metrics, with the climate exerting greater influence on functional traits and soil properties playing a dominant role in shaping diversity patterns. This study highlights the distinct responses of biodiversity and functional trait attributes to environmental shifts, emphasizing the importance of integrating multidimensional and multitrophic perspectives to advance our understanding of community assembly processes.

Gut health and physiological aspects of broiler chicken fed zeolite as a dietary supplement: its effect on growth, cecal microbiota and digesta viscosity, digestive enzymes, carcass traits, blood constituents and antioxidant parameters.

This study investigated the impact of dietary zeolite supplementation on growth, cecal microbiota and digesta viscosity, digestive enzymes, carcass traits, blood constituents, and antioxidant parameters of broilers. A completely randomized design was used with 240 one-day-old broiler chicks randomly assigned to three dietary treatments (0%, 1.5%, and 3% zeolite as a feed additive) with four replicates of 20 chicks each.

Background: Plant roots release root exudates to attract microbes that form root communities, which in turn promote plant health and growth. Root community assembly arises from millions of interactions between microbes and the plant, leading to robust and stable microbial networks. To manage the complexity of natural root microbiomes for research purposes, scientists have developed reductionist approaches using synthetic microbial inocula (SynComs).

Background: Rare genetic variation provided by whole genome sequence datasets has been relatively less explored for its contributions to human traits. Meta-analysis of sequencing data offers advantages by integrating larger sample sizes from diverse cohorts, thereby increasing the likelihood of discovering novel insights into complex traits. Furthermore, emerging methods in genome-wide rare variant association testing further improve power and interpretability.

Background: Adequate sleep is crucial for children's health, especially for children with ADHD and concurrent sleep problems. There is a need for more studies focusing on sleep problems in children with ADHD as these problems may exacerbate ADHD symptoms and vice versa, impacting negatively on everyday life. The aim of this study was to investigate the differences in health-related factors between children with ADHD without clinically relevant sleep problems and those with clinically relevant sleep problems after a sleep intervention.
