Capitellids of the genus Scyphoproctus are most readily identified by distinctive pygidial region, generally consisting a number segments fused with pygidium, forming weakly or well-developed anal plaque. To date, there 17 valid species, however, only one species has been previously recorded in Brazil. The aim this study was to investigate diversity occurring along Northeast and Southeast coasts sublittoral areas Three new have found samples collected variety habitats depths, paivai sp....
The genus Leiocapitella was described as having a wide variation on the number of thoracic chaetigers (13-17); however, this added to diagnosis based undescribed species. A shortening in range is proposed until re-examination these species and formal description be made. Currently, there are five valid single has been previously recorded Brazil. aim study investigate diversity occurring Southeast new found samples collected subtidal areas, sensibilis sp. nov., it compared other genus....
The sibling species of Capitella capitata are globally known for their tolerance to disturbed habitats and the C. complex is often used as an ecological indicator. A recent re-description proposed that capitata, originally described in Greenland restricted Artic Subarctic regions. Given relevance, we conducted a morphological molecular analyses based on mtDNA sequences investigate diversity distribution along Brazilian coast. Our data were congruent revealed existence four new distinct from...
Abstract Increasing habitat modification and species loss demand consistent efforts to describe understand biodiversity patterns. The BIOTA/FAPESP Program was created in this context it has been a successful initiative promote studies on conservation Brazil. BIOTA/Araçá is an interdisciplinary project that provided detailed evaluation of the Araçá Bay, coastal seascape located North coast state São Paulo, Southeast bay encompasses multiple habitats, such as beaches, mangroves, rocky shores,...
The iAtlantic Project has established an international collaborative strategy to improve mapping and characterization of deep open ocean ecosystems in understudied regions the Atlantic evaluate their health. In December 2022, first expedition South set off map explore seafloor Santos Basin slope (200-1,000 m depths) collaboration with Petrobras ‘Santos - Regional Characterization Project.’ 17-day ‘iAtlantic_BR10-Petrobras’ cruise was conducted on board research vessel NPqHOc Vital de...
Nano-size structures, nanotubes/multi-layer graphene (CNT/MLG), were dispersed into epoxy system by a combination of sonication and high shear mixing. To avoid CNT/MLG agglomeration, non-covalent functionalization performed using surfactants, CO890 - Polyoxyethylene (40) nonylphenyl ether SDBS sodium dodecyl benzene sulfonate. Raman spectroscopy Fourier transformed Infra-red analysis indicated that CO890-MLG SDBS-CNT have strong chemical interactions. Atomic force microscopy revealed...
Abstract: Polychaetes are common in coastal and estuarine environments worldwide constitute one of the most complex groups marine invertebrates. The morpho-physiology female reproductive system (FRS) can be understood by using histological tools to describe cycle gametogenesis paths and, among other purposes, aiming identify differentiate polychaete species. However, this histology-based approach is rarely combined with molecular tools, which known accurately delimitate In same way,...
The Amapá margin, part of the Brazilian Equatorial Margin (BEM), is a key region that plays strategic role in global climate balance between North and South Atlantic Ocean as it strictly tied to equatorial heat conveyance fresh/salt water equilibrium with Amazon River. We performed new scientific expedition on continental shelf (ACS, northern platform) collecting sediment using instrumental observation at an unstudied site. show here preliminary outcomes following applied methodologies for...
Mechanical properties of carbon/epoxy composites modified by the addition nanofillers has been investigated. Many studies have reported carbon based nanostructures, i.e. nanotubes (CNT) and graphene, as in different composite materials, with an increase on its mechanical properties. Nevertheless, individual nanostructures tendency to agglomerate when energy provided dispersion process, such sonication, high shear mixing, etc., is removed. The use surfactants seems be a promising route...
The Brazilian Continental Margin hosts several deep seafloor landscapes. However, this margin is still poorly studied and monitored, compared to coastal continental shelf areas, historically limited areas of particular economic interest. Some studies financed by the oil gas company have been conducted off Southeast (SE) Brazil (Esprito Santo Campos Basins) as part environmental licensing process for resource exploration. Similar results showed that annelid polychaetes dominated on upper...
