Paleolimnological studies of Laguna Chica of San Pedro (VIII Region): Diatoms, hydrocarbons and fatty acid records
(Sociedad de Biología de Chile, 2000)
Spatiotemporal structuring factors in the Chironomidae larvae (Insecta: Diptera) assemblages of an ultraoligotrophic lake from northern Patagonia Andean range: implications for paleolimnological interpretations
(Springer, 2020-01)
Chironomid larvae assemblages and their seasonal variations were analyzed in several substrate types from Lake Moreno Oeste (Northern Patagonia) in order to understand the spatiotemporal patterns controlling its community. ...
Bromine as indicator of source of lacustrine sedimentary organic matter in paleolimnological studies
(Academic Press Inc Elsevier Science, 2019-07)
Bromine (Br) to organic matter (OM) concentration ratio is studied in lake sediment sequences to provide information on environmental changes modifying OM production. The sequences studied were extracted from shallow lakes ...
South American lake paleo-records across the Pampean Region
(PAGES, 2009-10)
Although paleolimnological studies in the Argentinean and Uruguayan Pampas are relatively incipient, they have already provided critical information on the regional response of aquatic systems to climate variability. ...
Factors that control the spatial and temporal distributions of phosphorus, nitrogen, and carbon in the sediments of a tropical reservoir
(2018-01-01)
The impacts of anthropic activities have had profound effects on the nitrogen (N) and phosphorus (P) cycles in many aquatic ecosystems. We investigated the spatial and temporal distributions of carbon (C), N, and P in the ...
Holocene stratigraphic evolution of saline lakes in Nhecolandia, southern Pantanal wetlands (Brazil)
(Cambridge Univ Press, 2017-11-01)
Nhecolandia is a fossil lobe of the Taquari River megafan and a prominent geomorphic subunit of the Pantanal wetlands because of the presence of >10,000 small lakes. We investigated the stratigraphic records of three saline ...
Geochemistry of the Upper Paraná River floodplain: study of the Garças Pond and Patos Pond
(2015-08-25)
The aim of this study was to investigate the temporal evolution of the supply of chemical elements to the Upper Paraná River floodplain and identify trends in the geochemistry of its drainage basin. The primary factor that ...
Paleolimnological evidence of environmental changes in seven subtropical reservoirs based on metals, nutrients, and sedimentation rates
(2021-11-01)
Paleolimnological research can shed light on a broad range of environmental concerns; however, such studies are scarce in reservoirs. To address this lack of knowledge, a paleolimnological investigation was conducted to ...
