Procurou-se utilizar opalas biogênicas, também conhecidas como espículas ou "pó-de-mico", como identificadoras de sedimentos lacustres ou marinhos. Para isso, analisaram-se camadas e horizontes de um Gleissolo Tiomórfico Húmico na região do rio Riacho, Aracruz, ES. Cada amostra de solo foi submetida a tratamentos específicos para o isolamento das espículas; posteriormente, elas foram identificadas em microscópico eletrônico de varredura. Verificou-se a presença de espículas de origem tanto lacustre como marinha e que estas, além de serem úteis na identificação da origem dos sedimentos, podem propiciar, pela sua forma, as condições geoquímicas do ambiente e a distância de transporte dos sedimentos.
This study aimed to identify lacustrine or marine sediments based on biogenic opals (also known as spicules). The layers and horizons of a Humic Gley Thiomorphic soil in the Riacho catchment area, Aracruz, state of Espirito Santo, Brazil, were analyzed. Each soil sample was specifically treated to isolate the spicules, which were then identified by an electronic microscope. It was possible to verify the presence of lacustrine as well as marine spicules. Moreover, the shape of the opals provided information on the conditions of the geochemical environment and transport distance of the sediments. |

Yield losses induced by a complex of begomoviruses are observed across all major tomato-producing areas in Brazil. Tomato severe rugose virus (ToSRV) is the most widespread begomovirus in the country. Conversely, tomato common mosaic virus (ToCmMV) displays a more restricted geographical distribution to areas associated with the Atlantic Rain Forest (ARF) biome, encompassing the States of Espírito Santo?ES, Minas Gerais?MG, and Rio de Janeiro?RJ. Here, we characterized 277 tomato-infecting isolates collected in fields located within the ARF biome from 2006 to 2018. ToSRV displayed the highest prevalence (n?=?157), followed by ToCmMV (n?=?95) and tomato interveinal chlorosis virus (n?=?14). Four other begomoviruses were also detected, but with very low incidences. ToCmMV was the predominant begomovirus in the ARF biome up to 2014?2015 with very low ToSRV incidence. Subsequently, ToSRV became the most prevalent species in ES and RJ, but ToCmMV was still predominating in the ?Zona da Mata? meso-region in MG. Due to the remarkable endemic distribution of ToCmMV, we carried out phylogeographical studies of this virus using information from all 28 available isolates with complete DNA?A sequences. The closest common ancestor of ToCmMV was more likely originated around Coimbra?MG area ? 25 years before the formal report of this viral species. So far, all surveys indicated tomatoes as the only natural hosts of ToCmMV with outbreaks occurring mainly (but not exclusively) in highland areas. ToSRV shows a more widespread incidence across both highland and lowland areas of the ARF biome.
