| 英文摘要 | Submerged macrophytes like Vallisneria spinulosa S. Z. Yan play vital roles in aquatic ecosystems by stabilizing sediments, improving water quality, and providing habitat for organisms. However, their populations are declining globally due to environmental stressors like light limitation and bioturbation. This study examined how shading and bioturbation by Procambarus clarkii (Girard, 1852) and Carassius carassius (Linnaeus, 1758) influence V. spinulosa growth and reproduction. Severe shading (50% and 75%) significantly reduced plant height, ramet production, and tuber formation, while mild shading (25%) had limited negative effects by slightly mitigated biomass loss, suggesting that moderate light reduction hardly constrains plant performance. P. clarkii intensified shading stress by mechanically damaging plant structures, causing substantial biomass and reproductive losses, particularly under low-light conditions. In contrast, C. carassius had minimal effects on plant growth and did not significantly interact with shading. While neither shading nor bioturbation strongly affected flowering phenology, P. clarkii tended to induce earlier flowering. These findings highlight the vulnerability of submerged macrophytes to combined light limitation and bioturbation, with invasive P. clarkii amplifying the negative effects of shading. Effective management strategies-including maintaining adequate light availability and controlling P. clarkii populations-are essential for conserving V. spinulosa and other submerged macrophytes under increasing anthropogenic pressures. |
