Erosion rates and landscape evolution of the lowlands of the Upper Paraguay river basin (Brazil) from cosmogenic Be-10
(Elsevier B.V., 2015-04-01)
The importance of Earth's low sloping areas in regard to global erosion and sediment fluxes has been widely and vigorously debated. It is a crucial area of research to elucidate geologically meaningful rates of ...
Dissecting maize diversity in lowland South America: Genetic structure and geographic distribution models
(BioMed Central, 2016-08)
Background: Maize landraces from South America have traditionally been assigned to two main categories: Andean and Tropical Lowland germplasm. However, the genetic structure and affiliations of the lowland gene pools have ...
Structural and functional responses of the oligochaete and aeolosomatid assemblage in lowland streams: a one-way-pollution-modelled ecosystem
(Institute of Ecosystems Study, 2015-04)
We investigated the responses of the assemblage of Oligochaeta and Aeolosomatidae to organic pollution; comparing taxonomic richness, diversity, abundance, and diet of the individuals inhabiting two lowland streams with ...
Effects of dredging on benthic diatom assemblages in a lowland stream
(Elsevier, 2009-12)
The objective of this study was to assess the effects of dredging on the structure and composition of diatom assemblages from a lowland stream and to investigate whether the response of diatom assemblages to the dredging ...
From the Atlantic coast to the lowland forests: stable isotope analysis of the diet of forager‐horticulturists in southern Brazil
(John Wiley & Sons Ltd, 2021-11)
In this study, we analyze the diet of forager–horticulturalist societies of southeast South America through different isotopic markers (δ13Ccollagen, δ13Capatite, and δ15N). The economy of these populations was based on ...
Assessing Future Habitat Availability For Coastal Lowland Anurans In The Brazilian Atlantic Rainforest
(Taylor and Francis Ltd., 2016)
Use of next-generation molecular tools in archaeological neotropical deer sample analysis
(Elsevier B.V., 2016-12-01)
Taxonomic identity and genetic variation of three bone samples from a late Holocene earth mound in the eastern Uruguayan lowlands were analyzed. Samples were initially identified by morphology as being from pampas deer ...
