Discs and discord: The paleontological record of Ediacaran discoidal structures in the south American continent
(Pergamon-Elsevier Science Ltd, 2019-01)
Discoidal sedimentary structures are commonly described in Proterozoic strata, and even more common in Ediacaran to lower Cambrian sedimentary successions. Many abiotic processes are able to produce such circular or discoidal ...
Caracterização de Estruturas Sedimentares Biogênicas do Estuário de Itaguaré, Bertioga, SP
(Universidade Estadual Paulista (Unesp), 2021-07-16)
Biogenic sedimentary structures are the result of the substrate bioturbation process by infauna specimens. Neoichnology focuses on the study of in situ structures in modern environments, and therefore makes it possible to ...
Influência de um vale na plataforma continental sobre as comunidades de recifes biogênicos no litoral do Rio Grande do Norte
(BrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM ECOLOGIA, 2019-02-22)
Natural communities are structured by physical and biological factors that drive
the local dynamics of species coexistence. On reef habitats, conditions such as currents,
waves, temperature, depth and nutrient availability ...
Albumin-mediated deposition of bone-like apatite onto nano-sized surfaces: Effect of surface reactivity and interfacial hydration
(Academic Press Inc Elsevier Science, 2017-05)
The bioactivity of an implant is displayed on its ability to induce heterogeneous nucleation of biogenic apatite onto its surface upon immersion in body fluids; forming, through this layer, a stable bond with the host ...
Enhancement of Peroxidase Stability Against Oxidative Self-Inactivation by Co-immobilization with a Redox-Active Protein in Mesoporous Silicon and Silica Microparticles
(2016)
Abstract
The study of the stability enhancement of a peroxidase immobilized onto mesoporous silicon/silica microparticles is presented. Peroxidases tend to get inactivated in the presence of hydrogen peroxide, ...
An integrate analysis of an Hauterivian coral biostrome from the Agrio Formation, Neuquén Basin, west-central Argentina
(Elsevier, 2013-02)
A coral biostrome from the lower Hauterivian of the Neuquén Basin, west-central Argentina, was examined in detail. Taxonomic analysis established it as a monospecific assemblage of the scleractinian colonial coral Stereocaenia ...
Byssal attachment etchings: a new bioerosion trace on recent oysters
(Taylor & Francis, 2013-11-18)
Byssate bivalves can be attached to hard substrates by byssal threads. Dissolution of the substrate to which they are attached may leave superficial bioerosion traces. This study reports the scars produced by byssus of ...
Substrate-controlled ichnofacies along a marine sequence boundary: The Intra-Valanginian Discontinuity in central Neuquén Basin (Argentina)
(Elsevier Science, 2012-11)
The Intra-Valanginian Discontinuity in the Neuquén Basin (Argentina) marks a dramatic sea-level fall within Lower Cretaceous strata, and can be mapped for tens of kilometers both along depositional strike and dip. In the ...
