- ItemConexões entre a pluma do rio amazonas, o carbono orgânico particulado e os padrões biogeográficos bentônicos na margem equatorial do Brasil(Universidade Federal do Espírito Santo, 2025-07-14) Pereira, Araiene Peres; Gaurisas, Daniela Yepes; https://orcid.org/0000-0003-0415-0834; http://lattes.cnpq.br/5871499512209882; Bernardino, Angelo Fraga; https://orcid.org/0000-0002-1838-4597; http://lattes.cnpq.br/7955326454008127; https://orcid.org/0009-0004-1524-6078; http://lattes.cnpq.br/8886724222446948; Mazzuco, Ana Carolina de Azevedo; https://orcid.org/0000-0002-8971-4119; http://lattes.cnpq.br/4991428802686665; Ciotti, Áurea Maria; https://orcid.org/0000-0001-7163-8819; http://lattes.cnpq.br/9709038244305541The Amazon and Guiana continental shelves comprise one of the most dynamic marine systems on the planet, shaped by the interaction between the river discharge of the Amazon and Orinoco Rivers and the regional ocean circulation. This complex hydrodynamics regulates the spatial distribution of particulate organic carbon (POC), a key element in the biogeochemical cycles of the Atlantic Ocean and in the structure of pelagic and benthic communities. Despite its importance, there are still gaps in knowledge about how the Amazon River plume influences the spatiotemporal dynamics of POC along the continental shelf, especially as it disperses toward northern Brazil. Therefore, we investigated this relationship by integrating Amazon River discharge data (Óbidos station), POC estimates derived from MODIS-Aqua imagery (2003–2023), and benthic invertebrate occurrence records from the OBIS database. The analysis revealed a clear pattern of hydrological seasonality, with fluctuations influenced by climatic events such as the El Niño–Southern Oscillation (ENSO), which directly affected COP availability in the region. The highest COP concentrations were observed north of the mouth of the Amazon, driven by the continuous transport of the Amazon plume by the North Brazil Current. In contrast, the Guiana Shelf showed lower concentrations, likely due to the retroflection of the plume toward the open ocean. This COP dynamic appears to be directly reflected in the composition of benthic communities. A total of 4,541 invertebrate occurrences were recorded, distributed across 12 phyla, with Arthropoda, Cnidaria, Echinodermata, and Mollusca predominating. The Mouth of the Amazon stood out for its high taxonomic richness, possibly favored by the high deposition of organic matter and the region's intense hydrodynamics. The dissimilarity observed between the Boca and Norte communities, as well as the similarity between Guiana and the Orinoco, suggest that the combination of river flow and marine circulation patterns strongly influences faunal organization. Species such as Xiphopenaeus kroyeri and Penaeus subtilis were representative of COP-rich environments, while corals and echinoderms were more frequent in areas with lower particulate matter input. These results indicate that COP distribution acts as one of the main ecological determinants of regional benthic structure. Finally, we highlight the impact of extreme climate events, such as the 2015–2017 El Niño, which reduced Amazon flow and COP concentrations by approximately 15%, highlighting the high sensitivity of this coastal system to global climate change.

In Vitória Bay, these ecosystems face increasing pressures from mean sea level rise and urban expansion, which limits the landward migration of mangroves. This study was based on the hypothesis that mangroves located at lower elevations, due to their greater exposure to potential erosive processes and frequent inundation, would exhibit lower carbon stocks, as such processes could have removed part of the previously accumulated carbon and compromised their retention capacity. This study aimed to quantify total ecosystem carbon stocks in mangrove forests and to compare these stocks with coastal vulnerability indices in the metropolitan region of Vitória, southeastern Brazil. Total carbon stocks were quantified for six mangrove sites, including aboveground vegetation and soils down to 3 m depth. A guided classification of Vitória Bay was conducted to assess vulnerability based on spatial interpolation maps and the Coastal Sensitivity Index (CSI) developed by Machado and Albino (2024), which considers parameters such as overall vulnerability, elevation, geology/geomorphology, sedimentary features, and proximity to the coastline and river mouths.To compare with the CSI, in situ data on flood frequency and duration, water column depth, and elevation of the mangrove fringe (using RTK GPS) were collected at the six sampled sites. Our results showed that total carbon stocks in the six mangrove forests ranged from 717 to 1481 Mg C ha⁻¹, with an average of 1028 Mg C ha⁻¹, with over 90% of the carbon stored in the soils. The CSI indicated the sampled areas had high overall vulnerability, with site A classified as very high vulnerability, particularly due to its geology/geomorphology and sedimentary characteristics. In situ data classified site A as highly vulnerable, as it showed the lowest average elevation (-1.28 m), indicating greater exposure to flooding. Contrary to the initial hypothesis that mangroves in lower areas would have lower carbon storage capacity due to potential erosion, the lower areas of the Bay of Vitória showed the highest carbon stocks. This suggests that, even under greater physical vulnerability to these pressures, these mangroves continue to play a significant role in carbon retention, possibly due to soil accretion driven by aboveground plant material associated with root systems. This study indicates that, in the protected estuarine mangroves of Vitória Bay, carbon stocks are not primarily associated with vulnerability to coastal erosion related to wave action, highlighting the importance of integrating local hydrodynamic characteristics and terrain topography into conservation strategies and adaptive management in the context of climate change.
- ItemRevisão taxonômica dos grupos de espécies conicus e secretus de Dissomphalus Ashmead (Hymenoptera, Bethylidae) da região neotropical(Universidade Federal do Espírito Santo, 2025-11-27) Amorim, Manuela Silva de; Brito, Chirlei Dias de; https://orcid.org/0000-0002-1081-744X; http://lattes.cnpq.br/8780654501265281 ; Azevedo, Celso Oliveira; https://orcid.org/0000-0002-2423-9388; http://lattes.cnpq.br/5868655333545172; https://orcid.org/0009-0003-8483-7712; http://lattes.cnpq.br/7808615366797575 ; Oliveira, Francisco Limeira de; https://orcid.org/0000-0002-4980-5454; http://lattes.cnpq.br/4934381159083196; Silveira, Orlando Tobias; https://orcid.org/0000-0002-5899-199X; http://lattes.cnpq.br/9654506257169791The present study provides an in-depth taxonomic revision of the conicus and secretus species-groups of Dissomphalus Ashmead (Hymenoptera, Bethylidae) from the Neotropical Region. Dissomphalus is the most speciose genus within Bethylidae, with cosmopolitan distribution, and accounts for 317 species in the Neotropics, over 50% of the recognized species from the world. The groups are used to facilitate alpha-taxonomic studies of the Pan-American species, however, the conicus and secretus species-groups have a history of overlapping characteristics that hinders accurate delimitation, for this reason we analysed 3.855 specimens. As a result we created 13 new species-groups, in addition to the ones revised, each with its own diagnosis. We found 115 species, of which 67 are new to science, 49 of them allocated in the species-groups proposed and 18 incertae sedis. We also revised 45 known species, of which four were previously allocated in other species-groups. We provide an updated taxonomic key for all the species of each group, as well as diagnosis for the known species, description and illustration for all the new species. Our results showed that there were many patterns of external morphology, tergal process and genitalia hidden in the revised groups, leading to association of species never done before and the identification of D. puteolus Evans and D. nanellus Evans after 56 years of its publication. Our findings also provides a clear understanding of the morphology of the tubercles of the species-groups analysed and the importance of understudied taxonomic characters, also correlating species-groups with geographical distribution. Thus a robust framework of species-groups revisions in Dissomphalus is provided, paving the way for future molecular, biogeographical, phylogenetic and morphology based studies.
- ItemPaisagens antropizadas ocupam áreas climaticamente adequadas para a diversidade de pequenos mamíferos na Mata Atlântica(Universidade Federal do Espírito Santo, 2025-08-20) Beraldino, Valéria Dallapícula; Rodrigues, Ana Carolina Loss ; https://orcid.org/0000-0002-8298-8555; http://lattes.cnpq.br/8415444657040950; https://orcid.org/; http://lattes.cnpq.br/0963640768050260; Paresque, Roberta; https://orcid.org/0000-0001-8177-4144; http://lattes.cnpq.br/5411026526760218; Santos, Gabriel Silva dos; https://orcid.org/0000-0001-7991-8807; http://lattes.cnpq.br/1714610835853424A Mata Atlântica abriga uma rica biodiversidade de espécies, incluindo os pequenos mamíferos, das ordens Didelphimorphia e Rodentia, os quais são bons bioindicadores para estudos de impactos antrópicos no habitat. Pressões antrópicas, como o desmatamento e estabelecimento de diferentes matrizes a partir da conversão de áreas florestais em paisagens antropizadas como agropecuária, silvicultura e urbanização, têm causado alterações significativas que impactam diretamente a diversidade desse e de outros grupos. Nesse contexto, o presente estudo avaliou o quanto as diferentes classes de uso e cobertura do solo ocupam áreas climaticamente adequadas para diferentes níveis de diversidade (alta, média e baixa) para pequenos mamíferos no bioma. Para isso, geramos um mapa de riqueza taxonômica potencial, a partir de modelos de distribuição de espécies baseados em variáveis bioclimáticas (temperatura e precipitação), que pressupõe que o habitat potencial para cada espécie corresponde às condições ambientais onde sua ocorrência é mais provável. Esse mapa foi combinado a dados espaciais de uso e cobertura do solo, e aplicamos modelos lineares generalizados para identificar a influência dessas classes sobre a diversidade nessas áreas. Os resultados indicam que áreas de alta diversidade apresentam mais de 50% de seu habitat potencial preservado, entretanto, a conversão do habitat em áreas antropizadas, que hoje ocupa mais de 20% das áreas é preocupante. Áreas de diversidade média apresentam redução do habitat potencial (~40%) e grande proporção de área ocupada por uso antrópico (~40%), enquanto em áreas de baixa diversidade, a ocupação antrópica ocupa cerca de 48% da área, restando cerca de 32% de habitat potencial. Esses resultados reforçam a importância da preservação e restauração de remanescentes florestais para a conservação da biodiversidade, oferecendo subsídios para a definição e implementação de áreas prioritárias para proteção e restauração. Além de evidenciarem a necessidade de fortalecimento e cumprimento das legislações ambientais voltadas à proteção da biodiversidade na Mata Atlântica, especialmente diante das tentativas recentes de enfraquecimento de leis ambientais e do aumento do desmatamento no bioma nos últimos anos.
