The gut microbiota is crucial for host health and can be impacted by various environmental disruptions, yet the effects of multiple pesticide exposures on farmland organisms' microbiomes remain largely unexplored. We assessed changes in a wild apex predator exposed to pesticides agricultural landscapes. Pesticides, including acetochlor quinoxyfen, which are supposed banned, were significantly positively correlated with certain key bacteria from Actinobacteria, Alphaproteobacteria Gammaproteobacteria classes. Our results light up potential collateral effect bacterial assemblages through unknown mechanisms. These could result dysbiosis promotion pathogens and/or selection that might allow organism detoxify organism. Although formal metagenomic analyses would required soon, these microbial shifts underline broader ecological consequences exposure, emphasising need integrated biodiversity conservation ecosystem management protect public health.

All species host a rich community of microbes. This microbiome is dynamic, and displays seasonal, daily, even hourly changes, but also needs to be resilient fulfill important roles for the host. In evolutionary ecology, focus dynamism has been on how it can facilitate adaptation novel environments. However, an hitherto largely overlooked issue that keep its in check, which costly leads trade-offs with investing other fitness-related traits. Investigating these natural vertebrate systems by collecting longitudinal data will lead deeper insight into mechanisms shape host-microbiome interactions.

Abstract The convergence of microbiome science with the One Health principle heralds a transformative era in biology, prioritizing collective well‐being humans, animals, and environment. This review delves into intricate dance between microbiomes their hosts, revealing profound impact on health, nutrient cycles, climate change. Championing unified approach to health issues across diverse kingdoms life, emerges as holistic strategy, underscored by proposed universal balance theory, “Balance Dynamic Factors.” theory spotlights equilibrium within microbial human‐animal‐environment interactions, offering revolutionary pathway global social well‐being. It paves way for disease prevention, equity, sustainability, all which are purviews balanced ecological system. We navigate challenges opportunities this integrative approach, culminating call action incorporation policies, precision medicine, legislation, eco‐health projects, education, thereby setting stage harmonious coexistence our planet.

The gut microbiota-immune-brain axis is a feedback network which influences diverse physiological processes and plays pivotal role in overall health wellbeing. Although research humans laboratory mice has shed light into the associations mechanisms governing this communication network, evidence of such interactions wild, especially young animals, lacking.
