Melanin and antipredatory defenses in Daphnia dadayana under UVR exposure Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2020-04-20 Laura Wolinski, Beatriz Modenutti, Esteban Balseiro
Ultraviolet radiation (UVR) exposure has potentially hazardous effects on aquatic life, even more in the southern hemisphere, which is close to ozone layer depletion. Aquatic animals living in shallow water cannot escape from UVR effects swimming down, so they have to generate other traits to confront it (i.e., enzymes or pigments). Daphnia is a worldwide freshwater genus that inhabits ponds and lakes

Streamside mobile mesocosms (MOBICOS): A new modular research infrastructure for hydro‐ecological process studies across catchment‐scale gradients Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2020-01-20 Patrick Fink, Helge Norf, Christine Anlanger, Mario Brauns, Norbert Kamjunke, Ute Risse‐Buhl, Mechthild Schmitt‐Jansen, Markus Weitere, Dietrich Borchardt
A key research aim for lotic ecosystems is the identification of natural and anthropogenic pressures that impact ecosystem status and functions. As a consequence of these perturbations, many lotic ecosystems are exposed to complex combinations of nonchemical and chemical stressors. These stressors comprise temperature fluctuations, flow alterations, elevated solute loads or xenobiotics, and all these

Changes in summer diatom composition and water quality in urban lakes within a metropolitan area in central China Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2020-01-20 Jia Liang, Chunling Huang, Mark A. Stevenson, Qianglong Qiao, Linghan Zeng, Xu Chen
Urbanization is altering water quality and biotic communities of lake ecosystems worldwide, especially in developing regions. In this study, the diatom community structure and water quality of the epilimnion were analyzed in 38 lakes (40 sampling sites) in Wuhan City (central China) to assess the impacts of urbanization on lake ecosystems. Diatom communities displayed clear variation along the urban‐to‐rural

The key role of increased fine sediment loading in shaping macroinvertebrate communities along a multiple stressor gradient in a Eurasian steppe river (Kharaa River, Mongolia) Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-12-17 Michael Schäffer, Claudia Hellmann, Saulyegul Avlyush, Dietrich Borchardt
Aquatic communities across the Eurasian steppe face increasing anthropogenic pressures due to rapid population growth, catchment‐wide land‐use changes, and climate change. The particular type, intensity, overlay, and legacy of impacts along longitudinal gradients of Eurasian river networks provide a unique setting to investigate ecological responses in identifiable multiple stressor environments. We

Response of stream fungi on decomposing leaves to experimental drying Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-12-13 Dev K. Niyogi, Chia‐Yi Hu, Brett P. Vessell
Climate change may lead to increased droughts in the future, which in turn may lead to increased periods of stream drying. We conducted an experiment to test the effects of drying on fungal communities and microbial activity on decaying leaves from a stream. Our experimental setup included immersion of maple leaf cores for 2 weeks in a small stream to allow for the colonization of microbes. Leaves

Climatically induced temperature instability of groundwater-dependent habitats will suppress cold adapted Clitellata species Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-11-08 Jana Schenková, Vendula Polášková, Martina Bílková, Jindřiška Bojková, Vít Syrovátka, Marek Polášek, Michal Horsák
Groundwater dependent ecosystems are recognized as biodiversity hotspots, being,apart many negative human impacts, highly threatened also by ongoing climate warming. Clitellata (Annelida) are dominant invertebrates of permanent fauna in spring habitats, representing a heterogeneous group including both specialized cold stenothermic and ubiquitous eurythermic species. Therefore, they seem to be a good

Neutral effects of turbidity across a gradient of vegetation density on the predation of juvenile mandarin fish (Siniperca chuatsi ) Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-10-16 Wei Li, Tanglin Zhang, Brendan J. Hicks, Chaowen Zhang, Zhongjie Li, Jiashou Liu
Mandarin fish Siniperca chuatsi is a widespread piscivorous species in lakes of the Yangtze River basin. However, their wild population has drastically declined, and survival and growth rates of stocked populations are low. Anthropogenic activities have reduced submersed vegetation and increased turbidity in lakes containing S. chuatsi, thus, we hypothesize that reduced submersed vegetation and increased

Urbanisation reduces litter breakdown rates and affects benthic invertebrate structure in Pampean streams Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-09-23 Marina Tagliaferro, Adonis Giorgi, Ana Torremorell, Ricardo Albariño
The Pampean region has become one of the most urbanised areas in South America with more than 91% of the Argentinean population. This region is ideal for human settlements that have historically chosen riverine grassland areas to settle. Consequently, urban streams are increasingly subjected to pressures affecting their functioning. The aim of this study was to assess urbanisation effects on two proxies

Conversion of tropical forests to agriculture alters the accrual, stoichiometry, nutrient limitation, and taxonomic composition of stream periphyton Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-09-18 Flavia Tromboni, Christine Lourenço‐Amorim, Vinicius Neres‐Lima, Steven A. Thomas, Monalisa Silva‐Araújo, Rafael Feijó‐Lima, Eduardo F. Silva‐Júnior, Thomas Heatherly, Timothy P. Moulton, Eugenia Zandonà
The conversion of forests to agriculture in tropical areas profoundly changes adjacent streams by modifying hydrological conditions, altering light regimes, and increasing nutrient concentrations. In this study, we used an integrative approach to examine how transformations of intact forests affected the physical, chemical, and biological properties of periphyton, in three Brazilian Atlantic rainforest

Silent invasion: Sinanodonta woodiana successfully reproduces and possibly endangers native mussels in the north of its invasive range in Europe Int. Rev. Hydrobiol. (IF 1.9) Pub Date : 2019-09-03 Maria Urbańska, Małgorzata Kirschenstein, Krystian Obolewski, Małgorzata Ożgo
The explosive global spread of Sinadonta woodiana, a large‐bodied unionid mussel of East Asian origin, potentially affects the functioning of freshwater habitats and threatens native mussels. Molecular data indicate that its invasion in Europe started with a single colonization event, followed by in situ adaptation. This study traces one of the possible routes of such adaptation. It documents a population
