A new dark-dotted species of Hypostomus Lacépède (Siluriformes: Loricariidae) from rio Paraguaçu, Bahia State, Brazil Neotropical Ichthyology
Zanata,Angela M.; Sardeiro,Byanca; Zawadzki,Cláudio H..
A new species of Hypostomus Lacépède is described from the rio Paraguaçu basin, Bahia State, Brazil. The new species is distinguished from its congeners by having black and conspicuous dots on a pale background, which are similar in size on the head, trunk, and fins, along with ventral surface of head and abdomen naked or the latter plated exclusively on its anterior portion, absence of ridges on head and trunk, and caudal-fin lobes relatively similar in length. The new species further differs from the sympatric H. chrysostiktos by having seven branched dorsal-fin rays instead of 10-11 and represents the eleventh siluriform species endemic to the rio Paraguaçu basin.

Acritarchs of the Ediacaran Frecheirinha Formation, Ubajara Group, Northeastern Brazil Anais da ABC (AABC)
Chiglino,Leticia; Gaucher,Claudio; Sial,Alcides N.; Ferreira,Valderez P..
We report for the first time the occurrence of organic-walled microfossils in Ediacaran limestones and marls of the Frecheirinha Formation, Ubajara Group, and the first Precambrian acritarchs so far reported for northeastern Brazil. The assemblage of the Frecheirinha Formation represents a low-diversity microflora comprising Leiosphaeridia, Lophosphaeridium and subordinated Bavlinella (=Sphaerocongregus). Their thermal alteration index (TAI) between 4+ and 5, suggests metamorphic temperatures exceeding 200-250°C. Higher temperatures are probably related to intruding granitic plutons (Meruoca, Mucambo). Reported δ13C values of carbonates of -3.5 ‰ VPDB (Vienna-Peedee Belemnite) at the base, passing up section into a positive plateau of up to +3.7 ‰, and...

Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective Acta Botanica
Silva,Joan Bruno; Germano,Shirley Rangel.
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the state. Therefore, this work aimed to inventory bryophytes on two outcrops in the municipality of Puxinanã, in Paraíba, addressing some of the ecological aspects of survival in xerophytic environments. Samples were collected once every two weeks from February 2010 to May 2011. The usual techniques of bryophyte sampling and herbarium preservation were employed. We recorded 21 bryophyte species (six...

Butterflies (Lepidoptera: Papilionoidea) of an urban park in northeastern Brazil Biota Neotropica
Melo,Douglas H. A.; Duarte,Marcelo; Mielke,Olaf H. H.; Robbins,Robert K.; Freitas,André V. L..
Abstract Despite being one of the groups most well studied in Brazil, the butterfly fauna of northeastern Brazil, especially north of the mouth of São Francisco River, is poorly known. The aim of this study was to inventory the butterfly fauna in a remnant of Atlantic Forest in the state of Pernambuco as a contribution to understanding the distribution of these insects. The study was carried out in a 384.7 hectares fragment of Parque Estadual Dois Irmãos, in the metropolitan region of Recife. The butterflies were sampled monthly with insect nets from August 2011 to July 2012 and from January to August 2016. Additional records were obtained from two entomological collections and from two previous visits to the area in July 2003 and August 2006. A total of...

C- and Sr-isotope stratigraphy of the São Caetano complex, Northeastern Brazil: a contribution to the study of the Meso-Neoproterozoic seawater geochemistry Anais da ABC (AABC)
Silva,Juan C.; Sial,Alcides N.; Ferreira,Valderez P.; Pimentel,Márcio M..
C-isotope and 87Sr/86Sr values for five carbonate successions from the São Caetano Complex, northeastern Brazil, were used to constrain their depositional age and to determine large variations in the C- and Sr-isotopic composition of seawater under the framework of global tectonic events. Three C-isotope stages were identified from base to top in a composed chemostratigraphic section: (1) stage in which delta13C values vary from +2 to +3.7‰ PDB and average 3‰ PDB, (2) stage with delta13C values displaying stronger oscillations (from -2‰ to +‰ PDB), and (3) stage with an isotopic plateau with values around +3.7‰ PDB. Constant 87Sr/86Sr values (~ 0.70600) characterize C-isotope stage 1, whereas slightly fluctuating values (from 0.70600 to 0.70700)...

Effects of tourist visitation and supplementary feeding on fish assemblage composition on a tropical reef in the Southwestern Atlantic Neotropical Ichthyology
Ilarri,Martina Di Iulio; Souza,Allan Tainá de; Medeiros,Paulo Roberto de; Grempel,Renato Grotta; Rosa,Ierecê Maria de Lucena.
The effects of tourist visitation and food provisioning on fish assemblages were assessed by visual censuses (stationary technique) carried out in a tropical reef in Northeastern Brazil. Comparisons of species abundance, richness, equitability, and trophic structure in the presence (PT) and absence (AT) of tourists suggest that tourist visitation and supplementary food influenced the structure of the fish assemblage, as follows: (a) diversity, equitability and species richness were significantly higher on the AT period, while the abundance of a particular species was significantly higher during PT; (b) trophic structure differed between the AT and PT periods, omnivores being more abundant during the latter period, while mobile invertivores, piscivores,...

Esfingídeos (Lepidoptera, Sphingidae) no Tabuleiro Paraibano, nordeste do Brasil: abundância, riqueza e relação com plantas esfingófilas Zoologia
Darrault,Reisla Oliveira; Schlindwein,Clemens.
Hawkmoths (Sphingidae) are among the major pollinators in tropical communities. Here the first survey of sphingids and related plants in Northeastern Brazil is presented. The sphingids were surveyed from March 1999 through April 2000 at the Reserva Biológica Guaribas, Mamanguape, Paraíba State. On black and mix light traps, 136 hawkmoths from 24 species were captured. Individuais of Erinnyis ello (Linnaeus, 1758), Isognathus menechus (Boisduval, 1875) and Xylophanes tersa (Linnaeus, 1771) represented 58% of the samples. One half of the recorded species show wide distribution in the Neotropics. Three species were registered for more than six months. Most of the species were found only in the dry or wet season. Pollen from 34 plant species were recorded by...

First record of Lonchophylla bokermanni (Chiroptera, Phyllostomidae) for the Caatinga biome Mastozool. neotrop.
Cláudio,Vinícius C; Silveira,Gustavo C; Farias,Solange G; Maas,Andrea S; Oliveira,Marcione B; Lapenta,Marina J; Alvarez,Martín R; Dias,Daniela; Moratelli,Ricardo.
Lonchophylla bokermanni is known from three localities in the southern portion of the Serra do Espinhaço, all located in the Cerrado of Minas Gerais. Based on recent material from two localities in the Caatinga of Bahia, northeastern Brazil, we report the species occurrence in the northern portion of Serra do Espinhaço. These new records extend the species distribution by more than 840 km and represent the first records of L. bokermanni in the Caatinga biome. The localities we report here are under severe anthropic pres­sure, and this distribution extension should not inhibit conservation efforts for the species.

Floristic surveys of aquatic macrophytes in reservoirs in the Agreste zone of Pernambuco State, Brazil Rev. Bras. Bot.
Xavier,Leonardo Rafael Chaves Coelho; Araújo,Talita Oliveira; Nascimento,Paula Regina Fortunato; Pereira,Sonia Maria Barreto.
We surveyed the aquatic macrophytes in reservoirs in Camocim de São Félix in the Agreste zone of Pernambuco State, Brazil. Plants were collected on a bimonthly schedule from November/2008 to May/2009 in four reservoirs, and 33 taxa distributed among 23 families were encountered. The family Cyperaceae had the greatest number of species, followed by Lemnaceae. The predominant biologic form was emergent (33.3%) reflecting the extensive shorelines around the reservoirs analyzed.

Habitat Structural Effect on Squamata Fauna of the Restinga Ecosystem in Northeastern Brazil Anais da ABC (AABC)
DIAS,EDUARDO J.R.; ROCHA,CARLOS F.D..
In this work, we surveyed data on richness and composition of squamatan reptiles and habitat structural effect in nine areas of restinga ecosystem in the State of Bahia, northeastern Brazil. The “restinga” ecosystems are coastal sand dune habitats on the coast of Brazil. Our main hypothesis is that the Squamata fauna composition along these restinga areas would be modulated by habitat structural. After 90 days of field sampling we recorded approximately 5% of reptile species known in Brazil. The composition of Squamata assemblages varied mainly based on the presence or absence of lizards of the genera Ameivula and Tropidurus. Our data showed that habitat structure consistently affected the composition of local Squamata fauna, especially lizards.

Rodrigues,Maria N.; Queiroz,Dulciene M. M.; Rodrigues,Rodrigo T.; Rocha,Andreia M.C.; Braga Neto,Manuel B.; Braga,Lucia L.B.C..
We investigated the prevalence and the risk factors for infection with Helicobacter pylori in a randomly-selected population of adults from a low-income community in Northeastern Brazil. Helicobacter pylori infection was determined by ELISA. Risk factors were assessed using a structured interview. Two hundred and four individuals were included in the study, including 49 males and 155 females, ranging from 18 to 80 years old. Overall, 165 of 204 participants (80%) were H. pylori positive, without significant gender differences (p= 0.49). The infection rate was of 84.7% in subjects 18 to 30 years of age, increasing to 92% in subjects 46-60 years old. Above 60 years old, the prevalence decreased slightly. As a whole, the prevalence of infection did not...

Ichthyofauna of Seridó/Borborema: a semi-arid region of Brazil Biota Neotropica
Silva,Márcio Joaquim da; Ramos,Telton Pedro Anselmo; Diniz,Virginia Dantas; Ramos,Robson Tamar da Costa; Medeiros,Elvio Sergio Figueredo.
The Seridó/Borborema region is located between the States Paraíba and Rio Grande do Norte and a priority area for conservation of the Caatinga. This region is under the hydrological influence of the middle portion of Piranhas-Açu River basin. Previous systematic inventories of the ichthyofauna of this Caatinga’s area are not significant. The Caatinga fish fauna is threatened due the advancement of historic anthropogenic activities, mainly agricultural. Furthermore, another relevant aspect is the recent governmental decision of transferring water from São Francisco River to other Northern river basins, which includes the Piranhas-Açu basin. This study performed a systematic survey of the Seridó/Borborema’s ichthyofauna. The sites were sampled during the...

Ichthyofauna of the Parnaíba river Basin, Northeastern Brazil Biota Neotropica
Ramos,Telton Pedro Anselmo; Ramos,Robson Tamar da Costa; Ramos,Stéfane Almeida Q.A..
The Parnaíba River is the largest hydrographic basin with its limits entirely within the northeastern region of Brazil. It is one of the few perennial rivers in the Brazilian Northeastern Region, running predominantly in the area of Caatinga on the eastern portion (with intermittent drainages associated to this type of environment), and partly extending into the Cerrado region on the western portion. The objective of this study was to describe the diversity of freshwater fishes of the Parnaíba River basin by conducting a comprehensive ichthyofauna inventory of the basin. The sampling design of this study was based on the placement of (1) Fixed Sites for seasonal collection (dry and wet season, two years) in the three portions of the main course of the...
