Potentially bioavailable metals in sediment from a tropical polymictic environment-Rio Grande Reservoir, Brazil
(SPRINGER HEIDELBERG, 2008)
Background, aim and scope Although many recent studies have focused on sediment potential toxicity, few of them were performed in tropical shallow aquatic environments. Those places can suffer short-time variations, ...
Nutrient concentrations in the Middle Paraná River: effect of the floodplain lakes
(E Schweizerbartsche Verlags, 2004-05)
Water composition and sediment calcium, iron, aluminium and phosphorus fractions were determined monthly during one year in the Middle Paraná River, a floodplain lake in permanent contact with it and a representative ...
Testate amoebae (Amoebozoa: Arcellinidae) as indicators of dissolved oxygen concentration and water depth in lakes of the Lacandón Forest, Southern Mexico
(Cnr Ist Italiano Idrobiologia, 2019-12-16)
The ecology of aquatic protists such as testate amoebae is poorly known worldwide, but is almost completely unknown in lakes of the northern Neotropics. To address this knowledge gap, we analyzed testate amoebae (Amoebozoa: ...
Two-year temporal response of benthic macrofauna and sediments to hypoxia in a tropical semi-enclosed bay (Cienfuegos, Cuba)

Oxygen isotope ratios ( 18O/ 16O) of hemicellulose-derived sugar biomarkers in plants, soils and sediments as paleoclimate proxy II: Insight from a climate transect study
(Elsevier, 2014-11)
The oxygen isotopic composition of precipitation (d18Oprec) is well known to be a valuable (paleo-)climate proxy. Paleosols and sediments and hemicelluloses therein have the potential to serve as archives recording the ...
The role of temperature and oxygen availability on the distribution of Corbicula largillierti
(Wiley Blackwell Publishing, Inc, 2020-12-17)
The invasiveness of Corbicula largillierti has been underestimated, but this bivalve is currently receiving more attention. The first study of the distribution of this species along one of the major basins of central ...
