Soil viruses, ubiquitous and abundant biological entities that are integral to microbial communities, exert pivotal impacts on ecosystem functionality, particularly within carbon (C) nitrogen (N) cycles, through intricate interactions with bacteria, archaea, fungi, other taxa. While their contributions soil dynamics increasingly elucidated, the specific roles of viruses in karst forest remain largely underexplored. Karst ecosystems (covering 15% global terrestrial surface) characterized by unique geological formations, thin patchy layers, high pH Ca2+, rapid hydrological dynamics, collectively fostering environmental conditions may shape viral ecology modulate C N cycling. This perspective synthesizes existing knowledge functions distinctive characteristics soil, proposing potential mechanisms which could influence cycling such fragile ecosystems. regulate cycles both directly indirectly via hosts, mainly including shaping community structure, mediating horizontal gene transfer metabolism, increasing availability alleviating nutrient limitations, promoting sequestration, mitigating climate change. work aims bridge biogeochemical providing insights into sustainable stewardship resilience. We delineate critical gaps propose future perspectives, advocating for targeted metagenomic long-term experimental studies diversity, virus–host-environment interactions, temporal dynamics. Specifically, we advocate following research priorities advance our understanding studies: (I) abundance, activity: characterizing activity forests using metagenomics complementary molecular approaches; (II) virus–host interactions: investigating between key taxa involved cycling; (III) impacts: quantifying lysis fluxes soil; (IV) modeling cycles: developing integrative models incorporate virus-mediated processes frameworks at different spatial scales. Such efforts essential validate hypothesized underlying mechanisms, offering a foundation nature-based solutions facilitate support ecological restoration vulnerable regions amid

Viruses, traditionally recognized as pathogenic agents, are increasingly acknowledged for their indispensable roles in sustaining biodiversity and fostering ecosystem stability. This review examines the multifaceted contributions of viruses, exploring influence on nutrient cycling, genetic diversification, regulation microbial populations. By mediating interactions, facilitating horizontal gene transfer, driving co-evolutionary processes, viruses shape intricate tapestry life across diverse ecosystems. The primary aim this study is to synthesize contemporary findings virology highlight universal ecological importance viruses. Drawing upon research conducted marine, terrestrial, extreme habitats, delineates mechanisms through which mediate balance. Utilizing meta-analyses global virome datasets, coupled with advanced metagenomics bioinformatics methodologies, investigation unveils nuanced interplay between viral activity functionality. results illuminate significant role regulating population dynamics, promoting evolutionary innovation, maintaining reservoirs critical resilience. enriches our understanding biogeochemical cycles biodiversity, establishing integral components Furthermore, it contributes a paradigm shift virology, advocating broader perspective that transcends traditional view mere pathogens. practical implications profound, providing insights conservation biology climate resilience strategies. reimagining keystones health, work underscores necessity integrating ecology into holistic environmental frameworks, advancing scientific knowledge sustainability.
