Urbanization shifts long‐term phenology and severity of phytoplankton blooms in an urban lake through different pathways

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(17), P. 4983 - 4999

Published: June 23, 2023

Abstract Climate change can induce phytoplankton blooms (PBs) in eutrophic lakes worldwide, and these severely threaten lake ecosystems human health. However, it is unclear how urbanization its interaction with climate impact PBs, which has implications for the management of lakes. Here, we used multi‐source remote sensing data integrated Virtual‐Baseline Floating macroAlgae Height (VB‐FAH) index OTSU threshold automatic segmentation algorithm to extract area PBs Lake Dianchi, China, been subjected frequent rapid vicinity. We further explored long‐term (2000–2021) trends phenological severity metrics quantified contributions from urbanization, change, also nutrient levels trends. When comparing 2011–2021 2000–2010, found significantly advanced initiation (28.6 days) noticeably longer duration (51.9 but an insignificant trend time disappearance. The enhancement algal use efficiency, likely induced by increased water temperature reduced concentrations, presumably contributed earlier while there was a negative correlation between spring wind speed PBs. Fortunately, that both frequency severe (covering more than 19.8 km 2 ) demonstrated downward trends, could be attributed and/or levels. Moreover, enhanced land surface caused altered thermodynamic characteristics lake, which, turn, possibly increase local temperature, suggesting differently regulate phenology Our findings have significant understanding impacts on PB dynamics improving practices promote sustainable urban development under global change.

Why does the Water in a Natural Pool from Transparent Turn into Pumpkin Soup Color?

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: April 29, 2025

Lakes, reservoirs, and ponds are crucial inland water bodies that provide essential resources deliver significant ecological, social, cultural services. As a key indicator of quality, identifying the causes color changes is paramount importance. The periodic reddish-brown "pumpkin soup" phenomenon observed in Clean Pool (CP) Heilong (HP) southwestern China has raised concerns about quality ecosystem health. We used analytical approaches including, nutrient elements, heavy metal concentrations, dissolved substances, algal community composition, δD-δ¹⁸O isotope models to investigate ecological geochemical mechanisms underlying this phenomenon. results indicate that, despite Bacillariophyta dominating HP, they not deciding factor changes. Instead, Fe(OH)₃ colloidal particles, which originate from groundwater-surface interactions influenced by redox environment fluctuations, identified as causing discoloration. Hydrological analysis reveals atmospheric precipitation groundwater dynamics significantly affect formation transport particles. distinct physical biological characteristics Clear Turbid Pools further accentuate landscape contrast between two column. This study challenges conventional assumption blooms sole cause anomalies, emphasizing critical role hydrogeochemical processes karst landscapes. Simultaneously, findings new insights into evolution regulation special habitats regions offer theoretical framework for managing similar bodies. Additionally, underscores importance integrating hydrological, geochemical, perspectives address complex environmental phenomena extreme terrain condition.
