Electivities and resource use by an assemblage of lizards endemic to the dunes of the São Francisco River, northeastern Brazil
(Papéis Avulsos de Zoologia, 2005)
This study describes the pattern of resource use by one assemblage of lizards inhabiting a desert-like dune field in the Brazilian Caatinga. We evaluated food and microhabitat availability and phases of lizard activity, ...
Eolian depositional phases during the past 50 ka and inferred climate variability for the Pampean Sand Sea, western Pampas, Argentina
(Elsevier, 2016-03)
The Pampean Sand Sea, which occurs from the Argentinian Pampas to the eastern Andean piedmont, hosts presently stabilized dune fields spanning the late Quaternary. This study integrates previous results and presents new ...
Geomorphological dynamics and human interactions in a semiarid valley in Northwestern Argentina: The Cafayate depression (Salta Province)
(Pergamon-Elsevier Science Ltd, 2021-04)
The aim of this study was to record the changes in the Cafayate region, Northwestern Argentina, over the last 50 years (1969–2019), with a focus on fluvial and dune systems, together with human activity. The multi-temporal ...
Planície fluvial e campo de dunas eólicas do médio rio São Francisco: cronologia de depósitos e sucessão de eventos geológicos no Quaternário do Brasil
(Universidade Estadual Paulista (Unesp), 2021-12-10)
Grandes rios, como o São Francisco, são sistemas dinâmicos cuja evolução depende de forçantes internos e externos, particularmente tectônica, nível do mar e clima. O São Francisco é o maior rio da porção mais oriental da ...
Tidal and longshore sediment transport associated to a coastal structure
(Elsevier, 2005-12)
In order to understand the subtidal marine dynamics relative to the coastal engineering works in the Bahía Blanca Estuary (Argentina), the balance of sediment transport caused by tidal currents was estimated in the Puerto ...
A community of flower-visiting bees (Hymenoptera: Apoidea) in the coastal sand dunes of northeastern Brazil
(Biota Neotropica, 2005)
We analyzed aspects of the community structure of Apoidea of a restricted area of dunes with restinga vegetation in Salvador, Bahia, Brazil. Standardized samples were taken for one year, 3 times a month from 6:00 a.m. to ...
The transgression of an erg - sedimentation and reworking/soft-sediment deformation of aeolian facies: the Cretaceous Troncoso Member, Neuquén Basin, Argentina
(Geological Society, 2005)
The Cretaceous Troncoso Inferior Member of the Huitrín Formation comprises fluvial and aeolian facies that form a drying-upwards succession within the Neuquén Basin. The basal fluvial sandstones were deposited as braided ...
