Abstract Lakes and reservoirs worldwide are increasingly experiencing depletion of dissolved oxygen (anoxia) in their bottom waters (the hypolimnion) because climate change eutrophication, which is altering the dynamics many freshwater ecological communities. Hypolimnetic anoxia may substantially alter daily migration distribution zooplankton, dominant grazers phytoplankton aquatic food webs. In waterbodies with oxic hypolimnia, zooplankton exhibit diel vertical ( DVM ), they migrate to dark...

Lake Reserv Manage. 35:277–291. In seasonally stratified lakes reservoirs, fluctuating hypolimnetic oxygen conditions the watershed can influence retention of metals their exchange between sediments water column. particular, (Fe) (Mn) cycling at sediment–water interface be dynamic response to variability within...
Cyanobacterial blooms are increasing in waterbodies worldwide because of anthropogenic forcing. Most occur at the water's surface, but some cyanobacterial taxa, such as Planktothrix, able to modify their buoyancy access more favorable growing conditions deeper waters. Here, we used situ fluorometry examine vertical distribution and biomass Planktothrix a seasonally anoxic reservoir for 3 consecutive summers. We also collected depth profiles photosynthetically active radiation, temperature,...
Physical and chemical gradients across ecosystems, such as stream-to-lake continua within human-made reservoirs, provide valuable opportunities to examine how organisms respond changing environments. We quantified the rate of dinoflagellate recruitment a small reservoir test hypothesis that are controlled by different factors along continuum. predicted would be tightly coupled with physics in riverine zone closely related water chemistry lacustrine zone. For dominant genus reservoir,...
