Often characterized as "sentinels of lake aquatic ecosystems", different life-form vegetation covering dynamics reflects both short- and long-term climate fluctuations human activities. Previous assessments often lack comprehensive spatiotemporal coverage dynamics, prompting a deeper understanding variations underlying drivers such change. This article first presents dataset semi-decadal-scale trends in 616 China's lakes (>10 km2) from 1986 to 2020, after validating machine learning method random forest (RF) by field investigations literature reviews. The total area nationwide was varied 10,345.40 km2 17,329.31 (a 67.51 % increase) since 1986, with growth rate 169.85 km2/yr. As the is mainly concentrated Tibetan Plateau Lake Zone (TPL) (55.99 %) Eastern Plain (EPL) (25.86 %), followed other regions. It identified changes experienced three periods: moderate (1986–1999), slight losses (2000–2010), marked recovery (2011–2020). Specifically, TPL most remarkable expansion, primarily contrbution submerged (SAV). found that smaller plain are more conducive vegetation, shown increase percentage (PAV) decrease size. But showed 2010 larger advantageous recovery, attributing climate-induced expansion. Furthermore, intricately shapes also exhibited relative advantages Geographic climatic factors played pivotal role, altitude notably influencing temperature precipitation, thus exerting considerable impact on growth. study have estimated semi-decade dynamic characteristics across China concluded ushered vigorous period around 2010, offering compelling evidence for increasing greening trend ecosystems.

Aquatic environments, including marine and freshwater ecosystems, are vital for ecological balance biodiversity. The rising global demand aquaculture products necessitates increased production, with intensified practices posing significant environmental risks. This review explores the pathways through which chemical pollutants, heavy metals, pharmaceuticals, stressors induce teratogenic effects in aquatic species. highlights impact of pesticide include triazine herbicides, organophosphate organochlorine insecticides, carbamates on life, emphasizing their interference endocrine systems developmental processes. Heavy metals like mercury, lead, cadmium, arsenic, chromium noted persistence bioaccumulative properties, disrupting cellular hormonal functions. Pharmaceuticals, NSAIDs, antibiotics, chemotherapeutic agents, exert by physiological pathways. Environmental includes temperature fluctuations, salinity variations, pH changes, oxygen level imbalances exacerbate pollutants. importance comprehensive management understanding these complex interactions is essential formulating efficient strategies to safeguard effective measures protect ecosystems
