| Six polychaete species belonging to the genera Namalycastis Hartman, 1959, Ceratocephale Malmgren, 1867, Laeonereis Hartman, 1945, and Rullierinereis Pettibone, 1970 were recorded as part of a systematic survey of the family Nereididae in estuaries, exposed sandy beaches, shelly soft bottoms, atolls and coral reefs of the Brazilian northeastern coast. Two new species, Rullierinereis auxiliadorae, from Ceará coast and Ceratocephale rocaensis, from Atol das Rocas, are described. |

| In this paper, we provide some available information about the occurrence and some taxonomic aspects of 19 species from the Superfamily Oplophoroidea in the southwestern Atlantic (Brazilian waters), with the update to 22 species of Oplophoroidea occurring in Brazilian waters. Samples were collected during two sets of surveys. The first was performed in 2009 and 2011 in the Potiguar Basin in northeast of Brazil (03–05°S; 38–35°W; between the States of Ceará and Rio Grande do Norte) under the framework of the project “Avaliação da biota bentônica e planctônica da Bacia Potiguar e Ceará (Bpot)”, with samples collected from bottom trawls in the continental slope at depth ranging from 150–2068 m. Second, under the in the framework of the ABRACOS (Acoustic along... |

| 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. |

| 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,... |

| 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. |

| We describe a new species of Oxyepoecus Santschi, 1926, Oxyepoecus regularis sp. nov., based on workers and a gyne collected in "Caatinga Arbórea" (Arboreal Shrubland) in Milagres and "Mata Seca" (Dry Forest) in Boa Vista do Tupim, both in the state of Bahia, Brazil. The gyne of Oxyepoecus browni Albuquerque & Brandão, 2004, collected in the same leaf litter ant survey, is also described. In addition, we present new records for Oxyepoecus species in Northeastern Brazil. |

| ABSTRACT The Serra do Urubu mountain range is considered a key biodiversity area. It is situated in the Pernambuco Endemism Center, one of the most threatened regions of the Brazilian Atlantic Forest. However, despite the high importance of this area little research on its herpetofauna has been performed. The present study presents an inventory of the herpetofauna of the region, through bibliographic review, searches in museum collections and field expeditions to the RPPNs Frei Caneca and Pedra D’Antas, in the municipalities of Jaqueira and Lagoa dos Gatos. The conservation status of the amphibians of the region is discussed. Five expeditions, between 2012 and 2013 were made. The methods employed were visual transect surveys, acoustic census and pitfall... |

| Abstract: The objective of this work was to model the spatial dependence and to map the rainfall erosivity index (EI30) in the semiarid region of Brazil. Registers of monthly erosivity from 210 rainfall stations were used, with daily time series equal to or greater than 15 years. Based on the values of the EI30, a spatial dependence model was made by adjusting the semivariogram. From the semivariogram models, erosivity isoline maps were generated with a kriging interpolator. According to the historical data series, the maximum monthly average value of the EI30 was observed in March, and the annual value ranged from 1,439 to 5,864 MJ mm ha-1 per year, classified as low and moderate, respectively. The highest EI30 values were obtained in the northern and... |

| Geographical variation in biophysical conditions may strongly influence the life history characteristics of widely distributed species, such as the Brazilian sharpnose shark, Rhizoprionodon lalandii (Müller & Henle, 1839). Here, we use original and secondary data of reproductive traits of R. lalandii to identify population differences among northern/northeastern and southern Atlantic waters of South America. In the southeast region, birth occurs between December and March, and the young become frequent along the coast between April and September. Mating occurs mainly between March and June, when females with bite marks are common. Females in early pregnancy occur between March and September. The reproductive cycle of R. lalandii in the... |

| ABSTRACT The semiarid region of northeastern Brazil has more than 53 million inhabitants who depend, directly or indirectly, on the resources that the region offers. Among these resources, the soil is highlighted as one of the most important. Due to the importance attributed to the knowledge on the pedological and morphological characteristics of the soils of the Brazilian northeastern semiarid region, the aim of this study was to identify and characterize the different soil classes on the Lavoura Seca Experimental Farm, in the municipality of Quixadá, Ceará, Brazil, through the traditional method of soil mapping. The selected site is located in the municipality of Quixadá, Ceará, with a total extension of approximately 190 hectares. A regular grid of 200... |
