The hydrographic basin of southeastern Espírito Santo comprises the systems of Rio Novo, Rio Benevente and small river basins of the Guarapari. The present study is part of a series of studies on the fish fauna of river basins in Espírito Santo State. Fourty-five geo-referrerenced points in rivers and rivulets of the region were evaluated, 13 in the Rio Novo basin, 23 in the Rio Benevente basin and nine in small river basins in the municipalities of Anchieta, Guarapari, and Vila Velha. The environment and fish fauna were documented at every point, reporting a total of 110 species (54 marine), belonging to 46 families and 17 orders, most of which are Perciformes (42 species). With the exception of marine species, most of the fishes belong to the orders Characiformes and Siluriformes, with 16 species each. The Atlantic forest along the rivers of southeastern Espírito Santo region is composed of ombrophylous forest, pluvial submontane forest and pioneer formations (swamps, coastal sand dunes, and mangroves). The wetlands and coastal lake environments in the area are submitted to intense disturbances, and in this sense, the conservation units are extremely important for their preservation. The regional endemism of freshwater fishes is commented on, as well as the presence of potentially new species in the study area.

The hydrographic basins of northern Espírito Santo comprises the systems of Itaúnas and São Mateus rivers. The present work is part of a series of studies on the fish fauna along Espírito Santo’s river basins. Forty-nine geo-referred points in rivers and rivulets of the area were evaluated, 20 in the Itaúnas basin and 28 in São Mateus basin. The environment and the taxonomic composition of the fish fauna were documented at every point, reporting a total of 83 species, including 47 freshwater species and 36 marine, belonging to 35 families and 11 orders. Among the freshwater fish species, the Siluriformes predominated, with 20 species, followed by the Characiformes, with 17 species. The Atlantic forest of northern Espírito Santo, known as “floresta de tabuleiros”, was originally composed of ombrophylous forest as well as swamps, coastal sand dunes, and mangroves. With the suppression of native forests, the region has suffered from desertification, and environmental conditions are similar to the northeastern semiarid region, where the run-off waters are dispersed or intermittent. The loss of environmental quality along river valleys is associated with the need to reestablish riverine aquatic conditions. Exotic species and risks of introductions need further studies in these areas. Rare or endangered species whose distributional range has diminished in response to environmental changes may function as biological indicators. Potentially new species are identified, and regional endemism and distribution patterns for freshwater fishes are discussed.

Studies on bat richness and diversity in coastal sand dunes (‘restinga’) are still scarce. Therefore, the objectives of the present study were to estimate bat richness in the restinga of Praia das Neves (state of Espírito Santo, southeastern Brazil) and to analyze species abundance. Ten sampling nights were carried out in May and July 2008, resulting in a sampling effort of 21,847.5 h.m2. We captured 125 individuals from 17 bat species. In this study, Tonatia saurophila was recorded for the first time not only in the state of Espírito Santo but also in the restinga ecosystem. The most abundant species was Artibeus lituratus with 32% of all captures. Surveys in coastal restingas are urgently needed in order to obtain more information about the bats living in this environment.

Abstract Sixty-two fecal samples of capybara (Hydrochoerus hydrochaeris) living in eight conservation units (CUs) across the state of Espírito Santo, southeastern Brazil, were assessed for the presence of eggs of liver flukes via sedimentation. Fasciola hepatica eggs were found in 37.1% (23/62) of the samples. Positive samples were found in six CUs (75%), three CUs located in the southern region of the state and three others in the metropolitan region of the capital city of Vitória. Identification of Fasciola hepatica eggs collected from capybara fecal samples were based on morphology, and confirmed using molecular methods. Our results suggest that capybaras may serve as a wild reservoir host for F. hepatica, possibly contributing to the epidemiology and geographic range expansion of this zoonotic parasite across its vast range of distribution in South America.

O tucano-de-bico-verde, (Ramphastos dicolorus) é uma espécie endêmica na Mata Atlântica e por isso se faz presente em diversas regiões brasileiras como: Espírito Santo, Minas Gerais e Goiás, mas sua presença se estende até o Rio Grande do Sul, Paraguai e nordeste da Argentina. É bom lembrar que nas regiões Sudeste e Sul do Brasil são encontrados em altitudes de 100 a 2.000 metros. O tamanho dos fragmentos florestais, afeta o tucano-de-bico-verde, tendo em vista que são raramente encontrados em locais menores do que 90 hectares. Este estudo de caso objetiva a compreensão e estudo mais precisos das estruturas ósseas de um tucano de bico verde (Ramphastos dicolorus), através da realização de um guia auxiliar de estudos anatômicos para médicos veterinários e biólogos, obtido através da Técnica de Osteologia, Osteotécnica e Osteomontagem.

Após um século de intensas produções agropecuárias, baseadas na monocultura do café, pecuária bovina extensiva e intenso ciclo madeireiro, as florestas do município de São Roque do Canaã se restringiram a pequenos fragmentos isolados, rodeados por ambientes não florestados. Mediante tal constatação, objetivou-se realizar o levantamento da cobertura florestal e caracterizar os fragmentos florestais localizados em São Roque do Canaã/ES utilizando métricas de ecologia de paisagem com uso de Sistema de Informação Geográfica (SIG), atrelado a uma análise ambiental desses fragmentos. Tais objetivos foram alcançados através da quantidade e frequência de classe de tamanhos dos fragmentos, Índice de Diversidade de Patton (DI), Índice de circularidade (C) e o Índice Perimetral (IP). Com base nos resultados, concluímos que o município possui 17,6% de sua área coberta por florestas, sendo que deste total, 67,7% possui área inferior a 3 ha e 91,8% possuem área inferior a 15 ha.  Por meio do mapeamento dos fragmentos florestais, verificamos que os fragmentos tendem para formatos irregulares com bordas dentadas, correspondendo a 49% do total. Cerca de 76% dos fragmentos tendem para formatos alongados e isolados, o que contribui para a perda de biodiversidade. Conclui-se que a vegetação florestal remanescente encontra-se fragmentada e a maioria dos fragmentos florestais observados apresentam tamanho considerado insatisfatório para manter a estabilidade e a autossustentabilidade ambiental. Evaluation of the Size and Shape of Forest Fragments Using Landscape Metrics for the Municipality of São Roque do Canaã, Northwest of Espírito Santo State A B S T R A C TAfter a century of intense coffee monoculture-based agricultural production, extensive cattle ranching and intense timber cycle, the forest cover of São Roque do Canaã (ES) were reduced to small, isolated fragments surrounded by non-forested environments. From this observation, this paper aims carrying out a survey of the forest cover and characterize the forest fragments located in São Roque do Canaã by metrics of landscape ecology approach, using the Geographic Information System (GIS) linked to the environmental analysis of the fragments. Main data was obtained by calculating the quantity and frequency of the size class of the fragments, Patton's Diversity Index (DI), Circularity Index (C) and the Perimeter Index (IP). We concluded that the municipality has 17.6% of its area covered by forests, of which 91.8% is 15 ha or smaller, and 67.7% is lesser than 3 ha. The fragments tend to irregular shapes with jagged edges, with a tendency to elongated shapes, characteristics that foster the deleterious consequences of the edge effect. In conclusion, the remaining forest vegetation is highly fragmented, mainly composed by very small and isolated fragments, which is considered unsatisfactory to maintain stability and environmental self-sustainability. Actions to recover vegetation, such as the implementation of ecological corridors, the creation of conservation units and agroforestry production systems are recommended ways to increase the percentage of forests in São Roque do Canaã.Keywords: Fragmentation, landscape ecology, edge effect, biodiversity, deforestation.

The South Espírito Santo river basins include the Rio Itapemirim basin, the small river basins in Marataízes and a portion of the Rio Itabapoana basin, in Southeast Brazil. Nighty-two geo-referenced sites were sampled: 23 in Itabapoana, 66 in Itapemirim and three in Marataízes. A species list has been prepared, giving habitat details. Seventy-nine species, in 31 families and 11 orders were, reported, 17 species being from marine or brackish-water/estuarine habitats. The great majority of freshwater species belong to the Siluriformes (29 species), followed by the Characiformes (19). Torrential rivers, protected by the Caparaó mountains, display the lowest richness, with only a few species recorded from the highest valleys. On the other hand, in lowland river valleys along the Serra das Torres, an exceptional diversity of stream fishes was observed. Because of the only known population of Trichogenes claviger, a relictual species of Trichomycteridae, in the river Caxixe, this area is highly strategic in planning conservation of the Icthyofauna of the Itapemirim basin. Some species from southern Espírito Santo were described based on material collected on the historic Thayer Expedition, which crossed the region in 1865. Likewise, Oligosarcus acutirostris, Astyanax microschemos and Trichogenes claviger were also described based on fishes from southern Espírito Santo. A high endemism of freshwater species was observed between southern Espírito Santo rivers and lower Paraíba do Sul, suggesting a common history among these rivers.

The occurrence of the species of the genus Brycon (Characiformes: Bryconidae) in Espírito Santo State is herein reviewed. Brycon opalinus, a species formerly known only from the upper rio Paraíba do Sul and upper rio Doce basins, is recorded for the first time in the rio Itapemirim, an independent coastal basin in southern Espírito Santo State, Brazil. With the records of B. opalinus, four Brycon species are now known from Espírito Santo State: B. insignis in the rio Itabapoana basin, on the boundary between Rio de Janeiro and Espírito Santo, B. opalinus in the rio Itapemirim basin, B. dulcis in the rio Doce basin, and B. ferox in the rio Barra Seca, rio Itaúnas and the rio São Mateus basins. Additionally worth highlighting is that several fisherman and local inhabitants report the occurrence Brycon vermelha in the rio Cotaxé, a tributary of the rio São Mateus in Espírito Santo and Minas Gerais states, although there are no preserved specimens of B. vermelha from river basins other than the rio Mucuri, in Minas Gerais state.

New Occurrences

One of the greatest obstacles to biodiversity conservation is the lack of information to prioritize efforts on practical actions. This lack of information comes mainly from absence of inventories in many areas where few groups have reasonably complete databases. The distribution of the dragonfly fauna of Brazil is little known - only 29% of the Brazilian territory presents data about the richness of Odonata. In this contribution, a database of Odonata species of Santa Teresa Municipality was built, Espírito Santo State, Brazil. The database has 627 specimens registered, 77 species distributed in eight families and thirty-eight genera, forty of these species are common, one endemic of the State of Espírito Santo, and nineteen endemic of Brazil. In relation to the measure of conservation, four species are present in the category Insufficient Data (DD), one present in the Nearly Endangered (NT) category, three species in the Vulnerable category (VU) and one in the category In Danger (EN). Twenty-five species are considered new occurrences for the city. These results suggest that the fauna of the studied region deserves attention and points to the interest in implanting future conservation units in the region of Santa Teresa municipality.

The concept of an explosion in freshwater ecosystems as a result of the release of accumulated energy, accompanied by the destruction of the steady climax successions of hydrocenoses is presented. The typification of local explosions as well as methods for assessing their risk during the development of river basins are shown. The change in atmospheric circulation, impaired phases of the hydrological regime of rivers, increasing the average temperature of the planet, including in Polesie to 0,6 ºC, deforestation leads to concentration and release of huge amounts of unmanaged terrestrial energy, which manifests itself in the form of disasters and emergencies. Hydroecological explosion is formed as a result of multifactorial external influence (natural and anthropogenic) on the water body in a certain period of time. Moreover, its level at wastewater discharge depends on the mass of recycled impurities and behaved processing capacity of the reservoir, and the mass of dumped on biocides and the possibility of the water flow to their dilution and to the utilization of non-toxic concentrations. In all these cases the preservation of "centers of life" in the tributaries of the first order – local fish reproduction areas contributed to ecosystem recovery, and the entire ecosystem has evolved from equilibrium to non-equilibrium with further restructuring after the explosion and environmental transition to a new trophic level. It means that hydroecological explosion can be researched as the logical course of development of living matter in abiotic environmental conditions, ending abruptly with the formation of new species composition cenoses and new bio-productivity. The buffer capacity of the water environment is reduced due to re-development and anthropic transformation of geobiocenoses of river basins, which leads to a weakening of life resistance. This applies particularly to the southern industrial regions of Ukraine, located in the arid zone that is even more relevant in the context of increased average temperature due to the greenhouse effect, as well as to Polesie (Western, Central and Chernihiv), had been exposed to large-scale drainage of 60-80th years, which contributed to the degradation of peatlands and fitostroma. Imposing the western trace of emissions from the Chernobyl accident to these areas had created the conditions of prolonged hydroecological explosion in an intense process of aging water bodies, especially lakes, change in species composition of fish fauna and the occurrence of neoplasms at the organismal level. Under these conditions, for the existence of man and the environment the vitaukta should be strengthened, i.e. buffer resistance and capacitance the aquatic environment, bioefficiency on the one hand and balanced using the energy deposited - on the other. This will restore the functioning of ecosystems "channel-floodplain", "riverbed-lake", reducing the energy load on the aquatic environment. Hydroecological explosions of natural origin can not be considered a pathology – it is a jump process of natural selection of species of biota. Another thing, if they are of anthropogenic origin and if the magnitude of such an impact is on the power of geological factors. Hydroecological explosions can be regarded as a manifestation of environmental wars that consciously or unconsciously, human society is waging against themselves and their kind in the river basins, so prevention of entropy increase in the aquatic environment and the prevention of hydroecological explosions is a matter of human survival. While the man - is not the final link in the development of living matter, it can develop without him, as matter is eternal, and the forms of its existence are different.
