Fishes are conspicuous and threatened components of reef ecosystems. Understanding the role of the variables that shape their assemblages is important to buffer species, fishery stocks, and habitats from anthropogenic threats. So, the influence of depth and topographic complexity on trophic guilds and body size of reef fishes was assessed by underwater visual censuses (UVCs) conducted in biogenic reefs, rocky reefs, and rhodolith beds interspersed with algae, invertebrates, and sand. The study area lies in the southern continental shelf of Espírito Santo state, Brazil, a region that has lacked thorough UVC surveys of biogenic reefs and rhodolith habitats. A total of 105 species belonging to 42 fish families were registered. Among the eight trophic guilds registered, mobile invertebrate feeders and herbivores were the most representative in terms of density and biomass. Biogenic and rocky reefs showed higher biomass, density and richness than rhodolith habitats due to greater topographic complexity, which promotes more food resources and shelter. The five habitats hosted distinct fish assemblages (guilds and taxonomic diversity) probably because of the varying ability of resources they provide. Nevertheless, all habitats were dominated by species of low trophic level. Large fish, especially macrocarnivores, were mostly found in the deepest zones. This pattern is associated with ecological preferences but could also be strengthened by overfishing on shallower sites, decreasing the abundance of top predators and influencing their depth distribution. Our results provide a baseline for future studies, presenting subsidies for the management of human activities and the conservation of marine ecosystems in southeastern Brazil.

We describe and illustrate Phyllanthus capixaba, a new species hitherto found in the state of Espírito Santo, Brazil. This new species is assigned to P. section Phyllanthus subsect. Phyllanthus and differs from their nearest species P. longipedicellatus by a set of characters such as aspect of branch distribution on the stem, number of pairs of secondary veins per leaf, appearance of tertiary veins and leaf margin, type of stigma, and surface aspect of pollen grains. We present distribution maps, informal conservation status, and phenological data for the new species, an identification key for the Brazilian species of P. subsect. Phyllanthus, and discuss its systematic position in the Phyllanthus section. [ABSTRACT FROM AUTHOR]

Oropouche fever is an infectious disease caused by an arbovirus called Orthobunyavirus oropoucheensis (OROV). It was first isolated in Brazil in 1955 and has since been reported in various states in Brazil, including an increase of 448.86% in positive cases in 2024 compared to 2023. The primary vector for OROV is Culicoides paraenses, although other mosquito species can also transmit the virus. The clinical manifestations of Oropouche fever are similar to other arboviruses, but there is no specific treatment or vaccine available. The disease has emerged in Espírito Santo, a coastal state in Brazil, with several positive cases identified. Prevention measures include environmental management and individual protection.

The "Funga Capixaba" have been overlooked for a very long time, leading to a gap in the local mycological knowledge. In order to create a preliminary and updated list of Ascomycetes and lichen-forming fungi from Espírito Santo state, Brazil we reviewed all specimens deposited in the VIES Herbarium and key references of former mycological studies. In our list, we report a total of 528 species belonging to 173 genera and 65 families. 422 are new records for Espírito Santo state, six species, Mazaediothecium uniseptatum, Cratiria chloraceus, Lecanora glaucoidea, Pyrenula montocensis, and P. oleosa, are new records both for the neotropics and Brazil, and Lobariella pseudocrenulata is also new to Brazil. We have increased the number of accepted macrofungi species names from 85 to 528, which makes the Espírito Santo state the 10th highest in terms of known fungal diversity among Brazilian states. An updated and preliminary list of macroscopic Ascomycota including lichen-forming fungi from Espírito Santo, comments, and a brief overview about the local mycology are provided.

Four new species of Mandevilla from inselbergs in Espírito Santo, Brazil are described, including illustrations, and maps. Mandevilla declinata resembles M. crassinoda but differs by leaf blades acuminate to long acuminate and longer corolla. Mandevilla fornograndensis is distinguished from morphologically similar species by its yellow corolla. Mandevilla mysteriosa is morphologically similar to M. lucida but differs by its longer petioles, leaf blade characters, shorter corolla tube, and smaller anthers; Mandevilla obovata resembles M. hatschbachii, but it is separated by its puberulent leaves, longer sepals, and white corolla. An informal evaluation of the conservation status according to IUCN guidelines is proposed for each species: M. declinata (VU: D2), M. fornograndensis (VU: D2), M. mysteriosa (VU: D2), and M. obovata (VU: B1ab(i,ii,iii)+2ab(i,ii,iii)). A key to the species of Mandevilla in Espírito Santo is included. Quatro novas espécies de Mandevilla são descritas dos inselbergs do estado do Espírito Santo, Brasil, incluindo ilustrações e mapas.

Background and aims – Parianella is a relatively recently described genus of the subtribe Parianinae (Poaceae, Bambusoideae, Olyreae) that includes two species, and it is supposedly endemic to the Bahian Coastal Forests in the central region of Atlantic Forest, Brazil. Herein, we describe and illustrate a new species of the genus, comparing it with the other species of Parianella. We also provide an updated distribution map of the genus and the conservation status of the new taxon. Material and methods – This study was based on the analysis of herbarium specimens and a literature review. The conservation assessment is based on field observations and spatial analyses, following IUCN guidelines and criteria. Key results – During a review of the Poaceae collection of the MBML Herbarium, two Parianinae specimens with interesting features were found. A detailed morphological analysis revealed that these specimens belong to a new species of Parianella. The new taxon was collected in two localities in the southern portion of the Brazilian state of Espírito Santo, one in the municipality of Santa Leopoldina and the other in the Duas Bocas Biological Reserve, municipality of Cariacica. Both localities are situated in the Krenák-Waitaká Forests, one of the three subregions of the central Atlantic Forest region, and an area of great floristic diversity, including bamboo species. Conclusion – Parianella capixaba represents the southernmost distribution of the genus known to date. With the description of this new species, the total number of bamboos in Espírito Santo state rises to 52 species in 18 genera. [ABSTRACT FROM AUTHOR]

Salicaceae (Malpighiales) has a pantropical distribution, with 58 genera and ca. 1,200 species, and the Neotropical region is its center of diversity. In Brazil, 20 genera and 104 species can be found, of which 35 species are endemic. Holding almost half of Salicaceae diversity of the Atlantic Forest domain, Espírito Santo state has registered 23 species and four genera. Facing a large number of unidentified vouchers from the north of the state and challenging diagnostic characters for specific delimitation, this work aims to provide a taxonomic survey of Salicaceae of the Rio Preto National Forest. To do so, monthly field expeditions were carried out from January/2018 to March/2020. Salicaceae of Rio Preto National Forest is represented by four genera and nine species, where the genus Xylosma (X. glaberrima) and the species Banara serrata are new records to Espírito Santo state. Casearia is the richest genus with six species. Characters such as thorns, stipules, leaf punctations, type of venation and leaf margin, position and morphology of the leaf glands, position and morphology (sessile or pedunculate) of the inflorescences, number of floral whorls and position of the disc lobes are the most important characters for specific recognition.

The Paulo César Vinha State Park (PEPCV), an important conservation unit in the state of Espírito Santo, has one of the richest angiosperm communities of any restinga area in Brazil, making it a priority area for biodiversity conservation. In this study, we perform an inventory of the PEPCV flora through an exploratory collection over the park area and compilation of data from botanical collections available in virtual herbaria. A total of 634 species were listed, distributed into 367 genera and 111 families of angiosperms, representing 43.75% of the species documented in the restingas of Espírito Santo. The richest families were Fabaceae (54 spp.), Cyperaceae (40 spp.), Orchidaceae (40 spp.), Myrtaceae (36 spp.), and Poaceae (30 spp.). Six species were recorded for the first time in the park, ten are endemic to the Espírito Santo, and about 10% of the species are threatened with extinction. We provide data on the habit, species distribution in phytophysiognomies, and endangered species. Finally, we discussed the importance of broad knowledge about the park's plants, exposing points to conserve specific areas with high antopic rate, and plans to preserve the biodiversity of this ecosystem.

This study represents the first overview of the epidemiological dynamics of SARSCoV-2 in Espirito Santo (ES) State, Brazil, filling in knowledge on this topic, observing data collected in the State, and aiming at understanding the epidemiological dynamics of the virus in ES, as well as its possible routes of transmission and dissemination. Our results highlight that, so far, nine lineages have been identified with ES State. The B.1.1.33 lineage was the first with the highest occurrence in ES, remaining predominant until September 2020. The second predominant lineage was Gamma, representing 45% of the samples. The Delta lineage appears on the State scene, proving to be the next dominant lineage. This research allowed us to understand how the lineages advanced and were distributed in the State, which is important for future work, also making it possible to guide sanitary control measures. Data analyses were made through the GISAID database for ES State showed that the pandemic in the State has been evolving dynamically with lineage replacements over the months since the first notification.

We describe two new species of Heteropterys (Malpighiaceae) endemic to the Atlantic Forest of Espírito Santo State, Brazil. Heteropterys eucalyptifolia and H. follianum belong to the Aptychia informal group, due to their petioles with a pair of glands at the base, sessile pedicels, petals exposed in the enlarging bud, and strongly heteromorphic filaments. Morphological descriptions, illustrations, a distribution map and information on the conservation status of the species are provided. [ABSTRACT FROM AUTHOR]

A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5–9.7 mm long, flower buds 3.5–4 mm in diameter, and by the calyx lobes that are 2–3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain. [ABSTRACT FROM AUTHOR]

A checklist of the amphibians of Santa Teresa municipality, in southeastern Brazil is presented based on fieldwork, examination of specimens in collections, and a literature review. This new amphibian list of Santa Teresa includes 108 species, of which 106 (~98%) belong to Anura and two (~2%) to Gymnophiona. Hylidae was the most represented family with 47 species (43%). Compared to the previous amphibian lists for Santa Teresa, 14 species were added, 17 previously reported species were removed, and 13 species were re-identified based on recent taxonomic rearrangements. Of the 14 species added, 11 (79%) were first recorded during our fieldwork and specimen examination. It is also the first list of caecilians for Santa Teresa. This list suggests that Santa Teresa has 0.16 species per km2 (i.e., 108 species/683 km2), one of the highest densities of amphibian species in the world at a regional scale. This richness represents 78% of the 136 anurans from Espírito Santo state and 10% of the 1,080 amphibians from Brazil. We highlight the need for long-term monitoring to understand population trends and develop effective conservation plans to safeguard this remarkable amphibian richness. [ABSTRACT FROM AUTHOR]

A new species of Characidium from southeastern Brazil is described based on morphological and molecular evidence from specimens collected between the rio Jucuruçu and rio Doce basins. The new species belongs to a group of species within Characidium with an unscaled area in the isthmus and is distinguished from these species, except C. alipioi, C. fasciatum, C. hasemani, and C. kamakan, by the greater distance (greater than 10% SL) and presence of 5-7 scales between the anus and the anal fin, and presence of 14 series of scales around the caudal peduncle. The species is distinguished from C. alipioi by having 4 series of scales above the lateral line (vs. 5 series) and greater distance between the anus and the anal fin; from C. fasciatum and C. kamakan, by the smaller body depth at the dorsal-fin origin, at the anal-fin origin, and at the caudal peduncle; from C. hasemani, by the short distances between the tip of the snout and the pelvic fin, the tip of the snout and the anal fin, and the tip of the snout and the tip of anal fin. The new species forms a presumably monophyletic group with C. alipioi and C. kamakan. [ABSTRACT FROM AUTHOR]

The article discusses about the time-space variations of the benthic communities found in 3 rocky shoes in the Esipirito Santo state, Brazil. Sampling of the benthic was held per 3 months from August 2006 to May 2007 through intersection points. Results for the study showed that the Chthamalus bisinuatus and Brachidontes were the most common taxa while the invasive benthic Isognomon bicolor were seen at small densities within the rocky shores. Results added that the coverage of the wave exposure and shore slope affected the variability of the benthic species.

Two new species of shallow water Tornidae are found in Espírito Santo state, Brazil, formally described herein. They belong to a complex group of tiny gastropods, in such the taxonomy is very confused. Cyclostremiscus mohicanus sp. n. is characterized by three well-developed spiral, equidistant carinas, working as base of three series of tall, aligned periostracal rods. Episcinia itanhuna sp. n. has as single sculpture a series of pustules in periphery, but the periostracum bears three series of peripheral fringes with irregular rods. The new species are compared with the allies, showing a close relation with Caribbean fauna, but possessing worthy differences. These similarities have raised misidentifications.

The article describes Markea atlantica, an endemic species of the Brazilian Atlantic Rain Forest. It is characterized by its hemiepiphytic habit with stems climbing by adventitious roots, few flowers, bell-shaped yellow-greenish corollas with purple stripes in the inner surface. The article also informs that M. atlantica is restricted to the coastal Atlantic forests of Brazil and speculates that such as disjunction reflected past connections between Amazonian and Brazilian Atlantic forests.

The article describes and illustrates Miconia ruschiana, a new species of Miconia (Melastomataceae) from the Atlantic Forest of Brazil. It informs that M. ruschiana can be recognized by the terete branches, shortly plinerved leaves, panicles with glomerulate ending branches, large flowers and ovaries that are densely covered by trichomes at the apex. The article also mentions that the new species is known from the mountains of Espírito Santo in eastern Brazil.

Merianthera is a genus endemic to rocky outcrops in eastern Brazil, with seven species, four of which are new and described here (M. bullata, M. eburnea, M. parvi/olia, M. verrucosa). The genus can be recognized by its caducous leaves, inferior ovaries and dry, rupturing fruits, as well as by the stamens with complex dorsal appendages. Merianthera is monophy-letic, and sister to a clade consisting of Dolichoura, Behuria and Huberia (all from tribe Merianieae); together these four genera are sister to Cambessedesia, but not closely related to other genera in tribe Merianieae, such as Meriania and Graffenrieda. Within the genus, there are two distinct clades, the first with two species with thite to pink petals and leaves abaxially covered with a dense indûment, both growing on sandstone and endemic to Minas Gérais (M eburnea, M. sipolisii). The other clade comprises the remaining five species, all with glabrous or glabrescent leaves and purple petals, growing on granitic/gneissic outcrops and endemic to Espirito Santo (M bullata, M. burlemarxii, M. parvifolia) or occurring in this state and also Minas Gérais (M verrucosa) or in both plus Bahia (M. pulchra).

The article presents a study on the composition of the amphibian fauna at Vitória in Espirito Santo, Brazil. Researchers examined specific literature and collections for the inventory which comprised 34 amphibian species in two orders, such as Anura and Gymnophiona, besides field expeditions. They also recorded Lithobates catesbeianus, an alien invasive species, from within the area. The richness of amphibians is believed to be related with the existence of adhesive pads in hylid toes. The study showed that most of the species are habitat generalists which are not imperiled with extinction.

We collected 330 serum samples from 55 dairy farms in the Basin of Caparaó, State of Espírito Santo, elaluated by microscopic agglutination (MAT) for eight serovars, found a frequency of 12.42% (41) of reactor animals for at least a serovar tested. Serovar hardjobovis presented himself as the most frequent among reactive sera with 41 (12.42%) samples, followed by Bolivia with 32 Hardjo sample (9.69%), sample Hardjo Lagoa 30 (9.09%) Hardjo Norma with 21 (6.36%), Hardjo WHO 20 (6.06%) and Wolffi with 8 (2.42%), with no positive reaction against serovars Pomona and Hebdomadis. Among the 41 samples reagents, 100% of them were reactive to serovar hardjobovis followed by serovar hardjobovis Bolivia with 32 samples (78.04%), sample Hardjobovis Lagoa 30 (73.17%), Hardjoprajitno Norma sample with 21 (51.21%), WHO Hardjoprajitno sample with 20 (48.78%) and serovar Wolfi with 8 (19.51%), with no front seropositivity to serovars Pomona and Hebdomadis. The results showed that the serovar Hardjobovis probably is the causative agent of most problems related to infection by bacterium of the genus Leptospira spp in this region. [ABSTRACT FROM AUTHOR]

The article focuses on the study of Asplenium truncorum, a newly-discovered fern that grows from the Brazilian Atlantic Rain Forest. The study reveals that the species can only be found in moist forests of coastal Brazil, specifically in the States of Bahia and Espirito Santo. The species was named truncorum because of its preference to live in tree fern trunks. Moreover, the species is described to be with erect rhizome, non-conform apical pinnae and membranaceous to chartaceous leaf texture.

Since 2010, a new rickettsiosis caused by Rickettsia parkeri, a species included in the spotted fever group (SFG) and transmitted by the tick Amblyomma ovale, has been described in Brazil. Considering that A. ovale does occur in the Espírito Santo state (ES), the present study aimed at preliminarily describing the epidemiology of R. parkeri in the Atlantic forest of this state. Between June 2016 and September 2018, 33 villages from nine municipalities of the ES were included in a study for the molecular detection and isolation of SFG rickettsiae from adult Amblyomma ticks collected on dogs with free access to the forest. Serologic screenings against SFG rickettsiae in these animals and their owners (humans) were performed through immunofluorescence assay (IFA) using antigens of Rickettsia rickettsii and R. parkeri. Additionally, local health secretariats were informed on clinical manifestations of R. parkeri infection and told to communicate any suspected case. A total of 280 adult ticks were collected and taxonomically classified as A. ovale (n = 152), Amblyomma aureolatum (n = 127) and Amblyomma sculptum (n = 1). Overall, Rickettsia DNA was detected in 12/266 ticks. The sequencing of PCR products revealed that 0.7% (1/144) and 0.8% (1/121) of the analyzed A. ovale and A. aureolatum ticks were infected by R. parkeri strain Atlantic rainforest, respectively, and 8.3% (10/121) of the A. aureolatum ticks infected by Rickettsia bellii. Among the above PCR-positive ticks, only one isolate from one A. aureolatum tick was successfully established in the laboratory. DNA extracted from the third passage of this isolate was designated as strain M9A and molecularly characterized using primers targeting the Rickettsia gltA gene, whose sequence matched 100% the corresponding sequences of R. bellii. Seroprevalence against SFG rickettsiae in sampled dogs (n = 83) was 41% or 57%, depending on the rickettsial antigen (R. rickettsii strain Taiaçu or R. parkeri strain Atlantic rainforest, respectively). A total of 37 (45%) canine sera showed titers to R. parkeri at least fourfold higher than to R. rickettsii antigen. Among humans, 10% (4/41) of the samples reacted to at least one rickettsial antigen, with the highest endpoint titer varying from 64 to 128 for R. rickettsii and R. parkeri; no human serum showed ≥4-fold difference between the highest endpoint titers. Finally, during the study period, suspicions on cases of R. parkeri-rickettsiosis were not informed by the health secretariats. Our results confirm the presence and exposure to R. parkeri strain Atlantic rainforest, associated with two anthropophilic tick species (A. ovale and A. aureolatum) parasitizing domestic dogs with unrestrained access to forest areas. Consequently, the occurrence of R. parkeri infection in humans inhabiting the Atlantic forests of ES should not be discarded., (Copyright © 2019 Elsevier GmbH. All rights reserved.)

Abstract: This study provides population genetic data for individuals of Vitoria, Espirito Santo, Brazil, a location not yet characterized for STR frequencies used for genetic identification studies. Allelic frequencies and other population data analysis are reported for the 15 autosomal-STR loci included in the PowerPlex®16 kit (CSF1PO, D13S317, D16S539, D18S51, D21S11, D3S1358, D5S818, D7S820, D8S1179, FGA, Penta D, Penta E, TPOX, TH01 and vWA). Allele and haplotype frequencies, gene diversity and discrimination capacity were also estimated for the PowerPlex® Y System (DYS19, DYS385, DYS389I/II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438 and DYS439). Blood samples were obtained from 226 unrelated volunteers (135 males and 91 females) residents in the city of Vitoria, representing a typical sample of the mixed ethnicity present in the Espirito Santo State, Brazil. Within the tested population, the total number of individuals typed for specific markers is: 226 for D13S317, D21S11, D3S1358, D7S820, D8S1179 and FGA; 225 for D16S539 and D5S818; 224 for D18S51; 223 for CSF1PO; 222 for Penta D and vWA; 220 for Penta E; 207 for TPOX and 142 for TH01. Y-STR haplotypes were analyzed for 102 unrelated males, being 71 of them present in the 135 autosomal-STR sample, and 31 new males tested only for Y-STR markers. All autosomal markers were in Hardy–Weinberg Equilibrium. Y-STR analysis identified 101 haplotypes, being 100 of them unique. [Copyright &y& Elsevier]
