The conventional water filtration approach for collecting environmental DNA (eDNA) has critical limitations. collection of eDNA via passive samplers (PEDS) been proposed as an alternative to the method. Here, we developed a novel and rapid sampling evaluated extent which this method enhances efficiency. We drove boats along transects across nine large natural lakes deployed PEDS either by briefly submerging them at each location ("angling") or towing in ("trolling"). One liter was also collected processed Fish biodiversity determined metabarcoding analysis extracts. Despite short total submersion time (42-66 min "angling") substantially fewer samples (PEDS: 3-6 samples; filtration: 21-33 per lake), generally detected more fish species lake well sample compared with filtration. Detection probabilities were significantly higher are superior since requires less equipment, labor, time, costs. Our innovative strategy is thus effective could be used biomonitoring systems.

Drought stress has a significant impact on the quality and quantity of lake water. Understanding this is crucial for preventing water security risks pollution recovery. However, there lack systemic understanding how drought affects quantity, they change in multiple dimensions. This manuscript established synthesized methodology with principles to judge applicability three steps application detect level under severe Xingyun Lake, China. Results show that (1) The Lake have synchronous evident response during 2009-2014. rainfall 2008-2015 declined by 22.9% normal, inundated area depth 2012 decreased 10.50% from 2002 1.38m average depth, respectively. index climbed above 1.21 after 2008, fluctuating around 1.42. (2) Under drought, indicators significantly changed terms overall feature, trend, eigenvalue, morphological characteristics. Set2008-2015 are different set2000-2007 not groups set1994-2000. characteristics set2008-2015 differs shown minimum, maximum, median, quartiles, extreme values. (3) Although NH3-N showed no change, deteriorated physical, chemical, biological aspects. TP, IMN, BOD5 more evidently than DO NH3-N. (4) Water grade indicator concentration sharply threatened deeply TP TN. scientifically constructed canbe employed cognition out research. And intervention time various regulating measures degradation recovery based multi-dimensional analysis evolution.

Qionghai Lake is an important freshwater source in the Yunnan–Guizhou Plateau. However, cyanobacterial blooms have been observed recently Lake, but their formation mechanism and control management are not well understood. Herein, phytoplankton, zooplankton, eutrophication, nutrients, biochemical indices were measured from May 2022 to April 2023. The results showed that predominated Anabaena sp. with a density of 1.11 × 107–18.87 107 cells/L. started northwestern area November then expanded entire lake until it peaked subsided February Protozoa dominated zooplankton while having no significant relationship Lake. trophic level index chlorophyll similar spatiotemporal trends density, water quality northwest was worse than other parts. Total nitrogen (TN) total phosphorus (TP) 0.41–0.54 0.021–0.045 mg/L TN TP positively correlated most environmental factor affecting bloom These findings might provide essential information for improving remediation
