ABSTRACT Hybrid bioclastic/siliciclastic coquinas are sedimentary accumulations typical of coastal‐ and shallow‐water settings, where wave breaking, longshore drift and wave shoaling drive sediment transport and control the final accumulations. These processes resulted in thick packages of sediments, as identified in the Lower Cretaceous depositional ...

Modulation of swimming in the gastropod Melibe leonina by nitric oxide [PDF]
Nitric oxide (NO) is a gaseous intercellular messenger produced by the enzyme nitric oxide synthase. It has been implicated as a neuromodulator in several groups of animals, including gastropods, crustaceans and mammals.

Experimentação antropofágica em "Brasiliana" [PDF]
O artigo busca pensar a coluna Brasiliana, da primeira fase da Revista de Antropofagia, como um experimento antropofágico. A coluna, além de ser uma seção fixa da Revista, é uma das partes que melhor incorporam os valores antropofágicos nesse primeiro momento da publicação: utiliza-se da montagem, procedimento artístico caro às vanguardas, para, de ...

Botanical collections remain limited in the mountainous areas of the Brazilian Atlantic Rainforest, which compromises biogeographic knowledge of endangered and locally endemic species and many others that have not yet been described. These gaps hinder the accuracy of biodiversity indicators, limit the discovery and description of new species, restrict ...

Bioluminescent signals spatially amplified by wavelength-specific diffusion through the shell of a marine snail [PDF]
Some living organisms produce visible light (bioluminescence) for intra- or interspecific visual communication. Here, we describe a remarkable bioluminescent adaptation in the marine snail Hinea brasiliana.
