1Why Lake Taihu continues to be plagued with cyanobacterial blooms through 10 years(2007–2017) efforts显示文摘With the expansion of urban, industry, and agriculture after World War II, eutrophication firstly emerged as a major water quality threat in small water bodies [1]. As the increasing magnitudes and scales of nutrient pollution and habitat alteration, many of the world's large lakes exhibit symptoms of eutrophication, e.g., toxic cyanobacterial blooms, deoxygenation, and habitat loss.Boqiang Qin Hans W.Paerl Justin D.Brookes Jianguo Liu Erik Jeppesen Guangwei Zhu Yunlin Zhang Hai Xu Kun Shi Jianming Deng 2019Science Bulletin2019,64,6:50
2Response of community composition and biomass of submerged macrophytes to variation in underwater light, wind and trophic status in a large eutrophic shallow lake显示文摘Light climate is of key importance for the growth, community composition of submerged macrophytes in lakes and, they, in turn, are affected by lake depth and the degree of eutrophication. To test the relationships between submerged macrophyte presence and the ratio of Secchi disk depth(SDD) to water depth, i.e. SDD/depth, nutrients and wind, we conducted an extensive sampling campaign in a macrophyte-dominated area of the eastern region( n = 36) in 2016 in Lake Taihu, China, and combined the data gathered with results from extensive physico-chemical monitoring data from the entire lake. We confirmed that SDD/Depth is the primary factor controlling the community composition of macrophytes and showed that plant abundance increased with increasing SDD/Depth ratio( p < 0.01), but that only SDD/Depth > 0.4 ensured growth of submerged macrophytes. Total phosphorus and total nitrogen also influenced the growth and community composition of macrophytes( p < 0.01), while Chl a was an indirectly affecting factor by reducing underwater light penetration. Wave height significantly influenced plant abundance( p < 0.01), whereas it had little effect on the biomass( p > 0.05). The key to restore the macrophyte beds in the lake is to reduce the nutrient loading. A decrease of the water level may contribute as well in the shallow bays but will not bring plants back in the main part of the lake. As the tolerance of shade and nutrients varied among the species studied, this should be taken into account in the restoration of lakes by addition of plants.Baili Dong Yongqiang Zhou Erik Jeppesen Kun Shi Boqiang Qin 2021Journal of Environmental Sciences2021,33,5:10
3杂食性鱼类对浅水水体底栖-浮游生境耦合作用的影响:微综述显示文摘浅水水体存在着强烈的底栖-浮游生境耦合作用,耦合的结果决定着水生态系统关键特征.在缺少大型水生植物的浅水系统中,底栖藻类和浮游藻类对光照和营养盐的竞争是底栖-浮游生境耦合最为重要的生态过程之一,但该过程受到杂食性鱼类的影响.本文以浅水水体的底栖-浮游生境耦合作用为切入点,综述了杂食性鱼类对浅水水体底栖-浮游生境耦合作用的影响过程及机理.一般而言,杂食性鱼类有利于提高水层营养盐浓度,促进浮游藻类生长,降低水体透明度,不利于底栖藻类竞争,从而加速水体富营养化.但不同种类的杂食性鱼类(如底栖杂食性鱼类、偏植物性饵料的杂食性鱼类、偏动物性饵料的杂食性鱼类以及小型杂食性鱼类)因食性差异,对底栖-浮游生境耦合的影响机理不同,产生的生态环境效应各异;即便同一种杂食性鱼类也可因发育阶段不同对底栖-浮游生境耦合产生不同的影响.在人类活动、全球变暖以及富营养化等多重因子胁迫下杂食性鱼类在鱼类群落结构中的比例上升,因此,杂食性鱼类对水生态环境产生的影响深远、复杂,值得持续关注.梅雪英 Vladimir Razlutskij Lars G.Rudstam Erik Jeppesen 唐雅丽 张修峰 刘正文 2021湖泊科学2021,33,3:8
4Salinization Increase due to Climate Change Will Have Substantial Negative Effects on Inland Waters: A Call for Multifaceted Research at the Local and Global Scale显示文摘Globally,temperature and precipitation patterns are predicted to change markedly as a result of climate change.Particularly,the regions with a cold or hot semi-arid climate and the Mediterranean climate zone are expected to be strongly affected.1,2 A 25%–30%decrease in precipitation and increased evaporation are expected by the end of the 21st century in the Mediterranean region,to be accompanied by an even stronger reduction in runoff of up to 30%–40%,1,2 and this will lead to increasing salinization of lakes in these areas.Erik Jeppesen Meryem Beklioglu Korhan Ozkan Zuhal Akyurek 2020The Innovation2020,1,2:6

6Importance and vulnerability of lakes and reservoirs supporting drinking water in China显示文摘Drinking water is closely related to human health,disease and mortality,and contaminated drinking water causes 485,000 deaths from diarrhea each year worldwide.China has been facing increasingly severe water scarcity due to both water shortages and poor water quality.Ensuring safe and clean drinking water is a great challenge and top priority,especially for China with 1.4 billion people.In China,more than 4000 centralized drinking water sources including rivers,lakes and reservoirs,and groundwater have been established to serve urban residents.However,there is little knowledge on the percentage,serving population and water quality of three centralized drinking water source types.We collected nationwide centralized drinking water sources data and serving population data covering 395 prefecture-level and county-level cities and water quality data in the two most populous provinces(Guangdong and Shandong)to examine their contribution and importance.Geographically,the drinking water source types can be classified into three clear regions exhibiting apparent differences in the respective contributions of rivers,lakes and reservoirs,and groundwater.We further found that overall,lakes and reservoirs account for 40.6%of the centralized drinking water sources vs.river(30.8%)and groundwater(28.6%)in China.Lakes and reservoirs are particularly important in the densely populated eastern region,where they are used as drinking water sources by 51.0%of the population(318 million).Moreover,the contribution to the drinking water supply from lakes and reservoirs is increasing due to their better water quality and many cross-regional water transfer projects.These results will be useful for the government to improve and optimize the establishment of centralized drinking water sources,which provide safe and clean drinking water in China to safeguard people's lives and health and realize sustainable development goals.Yunlin Zhang Jianming Deng Boqiang Qin Guangwei Zhu Yinjun Zhang Erik Jeppesen Yindong Tong 2023Fundamental Research2023,3,2:3
7From unusual suspect to serial killer: Cyanotoxins boosted by climate change may jeopardize megafauna显示文摘The recent mass mortality event of more than 330 African elephants in Botswana has been attributed to biotoxins produced by cyanobacteria;however,scientific evidence for this is lacking.Here,by synthesizing multiple sources of data,we show that,during the past decades,the widespread hypertrophic waters in Southern Africa have entailed an extremely high risk and frequent exposure of cyanotoxins to the wildlife within this area,which functions as a hotspot of mammal species richness.The hot and dry climatic extremes have most likely acted as the primary trigger of the recent and perhaps also of prehistoric mass mortality events.As such climate extremes are projected to become more frequent in Southern Africa in the near future,there is a risk that similar tragedies may take place,rendering African megafauna species,especially those that are already endangered,in risk of extinction.Moreover,cyanotoxin poisoning amplified by climate change may have unexpected cascading effects on human societies.Seen within this perspective,the tragic mass death of the world's largest terrestrial mammal species serves as an alarming early warning signal of future environmental catastrophes in Southern Africa.We suggest that systematic,quantitative cyanotoxin risk assessments are made and precautionary actions to mitigate the risks are taken without hesitation to ensure the health and sustainability of the megafauna and human societies within the region.Haijun Wang Chi Xu Ying Liu Erik Jeppesen Jens-Christian Svenning Jianguo Wu Wenxia Zhang Tianjun Zhou Puze Wang Shingirai Nangombe Jinge Ma Hongtao Duan Jingyun Fang Ping Xie 2021The Innovation2021,2,2:3
