中国锹甲科昆虫分布格局及肠道菌群研究进展

Reviews on the Distribution Patterns and Gut Bacterial Community Research of Stag beetles in China

  • 摘要: 锹甲科(Lucanidae)昆虫是鞘翅目金龟总科的一个重要类群,以其独特形态特征和生物多样性而闻名,同时也是评估森林生态系统健康状况的重要指示生物。然而,随着全球气候变化的加剧,锹甲科昆虫的生存和分布面临着新的挑战。综述了在中国分布的锹甲的分类特征、分布格局及其肠道菌群等方面的研究进展,综合分析认为,锹甲科昆虫的分布格局可能与其对森林生态系统严格栖息选择密切相关。此外,肠道微生物群落的结构和多样性对宿主的生命活动具有重要影响,而温度升高可能进一步改变肠道菌群的组成和功能。基于此,进一步提出未来需要加强气候变化对锹甲科昆虫分布影响的长期监测,深入研究其肠道微生物群落结构与生态适宜性之间的关系,以及物种多样性形成机制等。这些研究对于揭示锹甲的生物多样性和物种保护具有重要意义。

     

    Abstract: The Stag beetles is an important group within the Coleoptera:Lucanidae, known for their unique morphology and biodiversity. It also serves as a crucial bioindicator for assessing the health of forest ecosystems. However, with the intensification of global climate change, the survival and distribution of Stag beetles are facing new challenges. This paper reviews the research progress on the taxonomy characteristics, distribution patterns, and gut bacterial community of Stag beetles. It is generally believed that the distribution pattern of the Stag beetles may be related to their strict habitat preferences for forest ecosystems. Additionally, the structure and diversity of gut bacterial communities play a significant role in the life activities of their, hosts, while rising temperatures may further alter the composition and function of these gut bacterial communities. Based on these findings, it is proposed that future research should focus on strengthening long-term monitoring of the impacts of climate change on the distribution of Stag beetles, in-depth investigation into the relationship between the structure of their gut bacterial communities and ecological suitability, as well as the mechanisms underlying species diversity formation.These studies are of great significance for understanding the biodiversity of Stag beetles and informing species conservation efforts in China.
