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.

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.

Collembola have significant influences on soil microorganisms and fertility but information on these ecologically important arthropods is lacking, especially in agricultural and tropical environments. This research was conducted to identify Collembola species present in the soil of papaya orchards in Espírito Santo, Brazil, and to compare the effect of conventional and integrated production on Collembola in this Neotropical environment. Soil samples (4.8 cm diameter, 10 cm deep) were collected in February, May, August and November 2003, from papaya orchards managed with conventional production (including pesticide application based on little or no pest monitoring or consideration of environmental impact) and integrated production (including selective pesticide application only when necessary based on regular pest monitoring) in one experimental site with three treatments (conventional; integrated with drip irrigation; integrated with microsprinkler irrigation) and four commercial orchards (two with conventional and two with integrated production). Berlese-Tullgren funnels were used to extract Collembola from the soil samples. Averaged over the sampling dates, collembolan densities of the orchards ranged from 14023 to 56001 Collembola per m². In the experimental site, the species Willemia brevispina, Folsomina cf. onychiurina, Folsomides cf. centralis, Folsomides parvulus, Cyphoderus cf. similis, and Neelus cf. minimus were more abundant with integrated versus conventional production. However, this difference was not apparent in commercial orchards sampled. Results indicate that relatively high populations and diverse communities of Collembola occur in the soil of papaya orchards in Espírito Santo but no collembolan species were found to be consistent biological indicators of conventional or integrated production. The species Acherontiella colotlipana, Willemia brevispina, Brachystomella agrosa, Friesea sublimis, Pseudostachia sp.1, Mesaphorura amazonica, Arlea sp.1, Salina sp.1, and Sphaeridia cf. pumilis are new records for the state of Espírito Santo, and Acherontiella colotlipana and Friesea sublimes, are new records for Brazil.

AbstractVitória Bay is located in the south-central part of the State of Espírito Santo (SES). Multiproxy analyses were performed on samples from a 490-cm-long sediment core collected at the coordinates 40°18′23′′W and 20°14′48′′S. The objective of this study was to identify and integrate the multiproxy data to determine the environmental dynamics during the Holocene. The material was subsampled every 10 m and submitted to standard methodological processing. The sediment core was dated to two depths: the oldest age was between 9396 and 9520 cal yr BP at a 480-cm depth, and the youngest age was from 7423 to 7511 cal yr BP at a 304-cm depth. The integrated analysis revealed evidence of three major environmental changes in Vitória Bay. The first phase had a fluvial influence (depth of 490–480 cm; 9396–9520 cal yr BP). This was followed by a transitional period (depth of 480–290 cm; 7423–7511 cal yr BP) with a salt influence due to the Last Marine Transgression (LMT). Later, the environmental stability was similar to that of today (290 cm to the core top). This was a reflection of the Last Marine Regression (LMR) in the Holocene.

Verbenaceae is represented in Brazil by 15 genera and ca. 290 species, with most of its richness in the Cerrado and Atlantic Forest domains. The state of Espírito Santo has an area of 46,184.1 km2, wholly embedded in the Atlantic Forest. Nonetheless, due to the intense environmental degradation in the state, only 10.5% of its original vegetation remains. The present study is part of the “Flora do estado do Espírito Santo” project and aims to provide a taxonomic treatment to Verbenaceae in the state, as well as to analyze its distribution patterns, together with preliminary conservation assessments for each species. It is based on morphological analysis of herbaria collections, field expeditions, and literature compilation. Distribution maps were made for each species, while the preliminary conservation assessments followed the criteria proposed by the IUCN. Verbenaceae is represented in the state of Espírito Santo by 31 species arranged in 11 genera: Aloysia (2 spp.), Bouchea (1 sp.). Casselia (1 sp.), Citharexylum (1 sp.), Glandularia (1 sp.), Lantana (10 spp.), Lippia (4 spp.), Petrea (1 sp.), Priva (2 spp.), Stachytarpheta (6 spp.) and Verbena (2 spp.). Eight species occurring in Espírito Santo are threatened with extinction. Three new records are verified, including species of the genus Lantana. The dense rainforest, which covers most of the state’s territory, presents the most significant number of species (20 spp.), followed by pioneer vegetations (12 spp.), seasonal semideciduous forests (11 spp.), inselbergs (8 spp.), and ecological refuges (2 spp.). The main richness centers for Verbenaceae in the state of Espírito Santo are the municipalities of Linhares, Santa Teresa, Vitória, Vila Velha, and Guarapari in this order. In contrast, the family is noticeably little represented in the northern region of the state, as well as near its borders, where the forest remnants are highly fragmented and scattered. The current results contribute to the taxonomic and biogeographic knowledge of Verbenaceae, to the creation of conservation strategies for threatened species in the State of sspírito Santo, and reinforce the need of fieldwork in several areas of the state.

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.

Taxonomic composition and spatio-temporal abundance of the ichthyofauna in Presidio River, Sinaloa, Mexico. The Rio Presidio in the southern Sinaloa, Mexico belongs to Nearctic-Neotropical zoogeographical transition zone, where its fish fauna could manifest changes in the abundance and distribution of the species during rainy and dry periods. The main objective of this study was to describe the taxonomic composition and spatial and temporal abundance of the fish fauna from the lower and middle Rio Presidio, by means of bimonthly samplings from April 2008 to February 2009. Forty fish species (39 native and 1 exotic) belonging to 32 genera and 19 families were registered. Two families (Gerreidae and Poeciliidae) contained the highest numbers of species (five and four, respectively). Six species (Lile stolifera, Oreochromis aureus, Awaous banana, Anchoa analis, Gobiomorus maculatus and Atherinella crystallina) in this order of importance contributed with almost 49 % of the total fish abundance. Species richness and salinity showed a direct relationship and an inverse relationship with the altitude. Based on the coefficient of similarity of species among sites two fish assemblages were identified. The first assemblage formed by species from marine derivation (peripheral) occurring in the lower part of the river, and the second assemblage by secondary freshwater species in the middle part. The higher fish species similarity observed in August and September was under the influence of the highest flows of the rainy period. Twenty-seven 27 species showed affinity to the Tropical Eastern Pacific Region, six species to the Neotropical region and two to the Nearctic region (Dorosoma smithi and Ictalurus cf. pricei ); one species has an Amphiatlantic distribution (Mugil curema), another is circumtropical (Mugil cephalus), two species have Amphiamerican distribution (A. monticola and G. cinereus), and one is exotic (O. aureus).

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.

Distribution Patterns

Stream development can generate environmental changes that impact fish communities. In temperate streams, the distribution of fish species is associated with environmental gradients. To analyze the relevant factors, large-scale exploration is required. Thus, to evaluate the distribution patterns of fish in Korea, sampling was conducted on a national scale at 720 sites over a 6-week period in 2009. A total of 124 fish species in 27 families were identified; Zacco platypus and Zacco koreanus of the Cyprinidae were the dominant and subdominant species, respectively. Of the species found, 46 (37.1%) were endemic and 4 (3.2%) exotic; of the latter, Micropterus salmoides and Lepomis macrochirus were widely distributed. Upon canonical correspondence analysis (CCA), both altitude and biological oxygen demand (BOD) were highly correlated with CCA axes 1 and 2, respectively. This explained 62.5% of the species–environment relationship. Altitude and stream order were longitudinally related to species distribution. The numbers of both total and endemic species gradually increased as streams grew in size to the fourth–fifth-order, and decreased in sixth-order, streams. Overall, fish communities were stable throughout the entire watershed, whereas some species showed site-specific occurrence patterns due to the paleogeomorphological characteristics of Korean peninsula. However, various anthropogenic activities may negatively affect fish communities. Therefore, both short- and long-term sustainable management strategies are required to conserve native fish fauna.
