Hanabanilla Reservoir, south-central Cuba, is used for electric power generation, potable water supply and tourism. We examined stratigraphic shifts in algal assemblages that accumulated in the reservoir sediments from the time of construction in 1960 through 2012, and inferred the environmental drivers of such biological changes. Historical fluctuations in algal assemblages were driven by scouring of the reservoir bottom, changing water level, and input of organic matter and nitrogen to the wat...

The Alianca Formation, within the Brazilian Reconcavo–Tucano–Jatoba Rift System, is a succession of Late Jurassic sedimentary rocks that record the maximum flooding surface of shallow Capianga Lake in the Afro-Brazilian Depression, Gondwana. Several aulacogens and drift-marginal Mesozoic basins of eastern Brazil and western Africa recorded the great extensional event that occurred during the early stage of Gondwana break-up. Lithologic, petrographic, micropaleontological and geochemical analyses...

We evaluated the feasibility of using testate amoebae to infer the quantitative paleohydrology of ombrotrophic mires during their early stages (fen and fen-bog transition) of development. Two transfer functions, one derived from ombrotrophic and the other from minerotrophic mires, were applied to a peat core from an ombrotrophic mire in a taiga region of west Siberia. An ombrotrophic transfer function was applied to the bog stage of mire development. In contrast, ombrotrophic and minerotrophic t...

The Murray River is Australia’s economically most important river system. As a result of its economic importance, land use change and river regulation have resulted in ecological degradation of the river and associated river wetlands (known throughout Australia as “billabongs”). Palaeolimnology can provide otherwise unobtainable information about the relative impacts of stressors and identify “refuges” from such impacts. We examine an approximately 1800 year history of water quality and vegetati...

The grain size of lake sediments has been widely used to reconstruct environmental processes. However, the various components of lake sediments are influenced by different factors, and therefore the environmental significance of grain-size variations may be complex. For example, in situ authigenic biological siliceous components cannot be used to indicate variations in hydrodynamic conditions. Here we present a case study of the effects of diatoms on the grain size of the sediments of Lake Kanas...

Despite a relatively large number of paleoenvironmental and archaeological studies in the Southern Urals, Russia, Holocene moisture dynamics in the region remain a subject of debate. Electrical conductivity (EC) of lake waters in the Southern Urals is climate-dependent and associated with effective moisture. I developed a transfer function using a 72-lake regional diatom dataset and inferred past EC using diatoms in sediment cores from three lakes. The diatom-inferred EC inferences were compared...

Salto Grande is a large South American reservoir on the border between Uruguay and Argentina that was impounded in 1979 and experiences recurrent, massive cyanobacteria blooms. A water-monitoring program was initiated 20 years after the dam was built, hence the causes and onset of cyanobacteria blooms remain poorly known. We collected two sediment cores from the old river channel in the reservoir (z = 17 m) and used physical, chemical and biological variables in the sediments, along with existin...
