Uma Abordagem para Detecção Automática de Planos em Modelos Digitais de Afloramentos Baseada em PCA
(Universidade do Vale do Rio dos Sinos, 2014-09-19)
The use of LIDAR (Light Detection and Ranging) systems for gathering spatial data has been extensively used in geological studies. This type of digital remote sensing delivers high resolution and accuracy, resulting in 3D ...
SyntheticSeis: a synthetic seismic software
(Universidade do Vale do Rio dos Sinos, 2021-02-18)
Synthetic seismic models derived from outcrop studies are useful for comparing with actual seismic data sets. This article presents the software we developed (SyntheticSeis) in terms of its architecture and validation ...

Crystalline rock outcrops in the Atlantic Forest of northeastern Brazil: Vascular flora, biological spectrum, and invasive species
(2013-06-01)
We studied the vegetation of two crystalline rock outcrops in the Atlantic Forest of northeastern Brazil. We recorded typically rupicolous species, which are rare or classified as extremely endangered, such as Aechmea ...

From micro- to macroevolution: insights from a Neotropical bromeliad with high population genetic structure adapted to rock outcrops
(Nature Publishing Group, 2020-07-17)
Geographic isolation and reduced population sizes can lead to local extinction, low efficacy of selection and decreased speciation. However, population differentiation is an essential step of biological diversification. ...
Imageamento digital de paleocavernas colapsadas com georadar
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Geodinâmica e GeofísicaGeodinâmica; Geofísica, 2012-04-27)
In this study, the methodological procedures involved in digital imaging of collapsed
paleocaves in tufa using GPR are presented. These carbonate deposits occur in the Quixeré
region, Ceará State (NE Brazil), on the western ...
Interações planta-polinizador em vegetação de altitude na mata atlântica
(2016-01-01)
Tropical high-altitude vegetation is unique due to susceptibility to severe weather conditions in relation to lower formations, and by the peculiarity of its flora with many relictual components. Studies on plant-pollinator ...
Composição florística de angiospermas no carste do Alto São Francisco, Minas Gerais, Brasil
(2013-01-01)
The occurence of carbonatic rocks defines a typical type of relief, called karst, that, by its geomorphology and hydrology, usually differs from the surrounding landscape. In the upper São Francisco river basin, some ...
