Global trends and regime state shifts of lacustrine aquatic vegetation

The Innovation, Год журнала: 2025, Номер 6(3), С. 100784 - 100784

Aquatic vegetation (AV) is vital for maintaining the health of lake ecosystems, with submerged aquatic (SAV) and floating/emergent (FEAV) representing clear shaded states, respectively. However, global SAV FEAV dynamics are poorly understood due to data scarcity. To address this gap, we developed an innovative AV mapping algorithm workflow using satellite imagery (1.4 million Landsat images) from 1989 2021 created a database across 5,587 shallow lakes. Our findings suggest that covers 108,186 km2 on average globally, accounting 28.9% (FEAV, 15.8%; SAV, 13.1%) total area. Over two decades, observed notable transition: decreased by 30.4%, while increased 15.6%, leading substantial net loss AV. This trend indicates shift conditions, increasingly progressing toward turbid states dominated phytoplankton. We found human-induced eutrophication was primary driver change until early 2010s, after which warming rising temperatures became dominant drivers. These trends serve as warning sign deteriorating worldwide. With future climate intensified eutrophication, these ongoing pose significant risk disrupting ecosystems.

Water Level Fluctuation Rather than Eutrophication Induced the Extinction of Submerged Plants in Guizhou’s Caohai Lake: Implications for Lake Management

Water, Год журнала: 2024, Номер 16(5), С. 772 - 772

The intensifying global decline in submerged aquatic lake plants is commonly attributed to eutrophication, while other drivers such as water levels are seldom considered. This study focused on the sudden extinction of Caohai Lake, Guizhou, and employed long-term data a whole-lake level manipulation experiment explore impacts nutrients changes plants. results indicated that over past 40 years, total nitrogen ammonia did not change significantly, phosphorus showed significant decreasing trend. In recent however, rose. biomass continuously increased until large-scale occurred 2021; chlorophyll also significantly increased. It speculated was caused by fluctuations rather than eutrophication. After restoration natural hydrological regime low winter spring high summer autumn, gradually recovered, with increasing 922.6 g/m2 2023. structural equation modeling depth bottom light availability were main for However, protection management, more attention often paid controlling nutrients, influencing factors neglected. These findings confirm importance shallow lakes, suggesting focus management vegetation restoration.
