A list of liverworts from Alagoas State was compiled and is presented here. The list is based on catalogues and previous papers as well as the results of an unpublished survey carried out at the Murici Ecological Station (EsEc), an important protected area of the Brazilian Northeast (9º11'05" - 9º16'48"S; 35º45'20" - 35º55'12"W). One-hundred and sixteen liverworts have been recorded for the state of Alagoas, of which 106 occur at EsEc Murici. Seventy-eight are new occurrences for Alagoas, and seven of these are also new occurrences for northeastern Brazil. Data on geographic distribution in Brazil and worldwide is given here, in addition to ecological and taxonomic comments on the species that are new occurrences for the Northeast region.

This study provides the first record of the exotic invasive bivalve Isognomon bicolor for the State of Paraíba, Northeastern Brazil. It has been found to occur in at least twelve coastal reefs along the coast. We also present its first record for the State of Alagoas and new record localities for the States of Rio Grande do Norte and Pernambuco, including its occurrence in hypersaline estuaries. From these records the distribution range of I. bicolor has been expanded to the littoral region of Northeast Brazil, where this invasive species seems well established.

We present the first record of Aegolius harrisii (Cassin, 1849) from the state of Maranhão, extending the known distribution of the species 283 km to the west in the Brazilian Northeast. This record also represents the northernmost locality of the species within the Cerrado phytogeographic domain, which coincides with the ecotone between the Cerrado, Caatinga, and Amazon domains. Given the considerable gaps in the data on the occurrence of this owl in the Brazilian Northeast, we would recommend more surveys in specific areas with similar phytophysiognomies.

A gestão eficiente dos recursos hídricos no Nordeste brasileiro torna-se fundamental diante do regime hidrológico dos rios intermitentes, dos quais muitos são extremamente críticos. Todavia estes dependem de um regime pluviométrico irregular, tanto em escala de tempo mensal quanto anual. Objetivou-se determinar a variabilidade espaço-temporal da precipitação pluviométrica total anual, averiguando-se, também, as regiões com padrões de precipitação semelhantes por técnicas de análise multivariada (clusters e componentes principais) no Nordeste do Brasil. Foram analisados dados de precipitação pluviométrica total anual, entre os anos de 1995 e 2016, de 37 diferentes estações meteorológicas do INMET, estas situadas nos limites territoriais dos nove estados do Nordeste brasileiro. A análise de clusters verificou a formação de quatro grupos distintos, com padrões semelhantes de precipitação nas regiões dentro dos grupos, conforme também observado na análise de componentes principais. A padronização e/ou variabilidade espaço-temporal da precipitação pluviométrica dos municípios analisados mostrou-se está intimamente associada as condições das estações do ano e anomalias climatológicas, aos fatores de uso e ocupação do solo, condições de altitude e relevo, tais quais favorecem na formação e estabilidade de chuvas menores ou maiores no Nordeste brasileiro. A análise multivariada de cluster e componentes principal identificaram padrões e semelhanças pluviométricas de grupos, nos diferentes estados do Nordeste do Brasil entre os anos de 1995 e 2016. Exploratory Inference of Spatial-Temporal Data of Rainfall in the Brazilian Northeast ABSTRACTThe efficient management of water resources in the Northeast of Brazil is essential in view of the hydrological regime of intermittent rivers, of which many are extremely critical, as they depend on an irregular rainfall regime, both on a monthly and annual time scale. The objective of this study was to determine the spatial and temporal variability of the annual total rainfall, also investigating the regions with similar rainfall patterns by multivariate analysis techniques (clusters and principal components) in Brazilian Northeast. Data from total annual rainfall between the years 1995 and 2016, of 37 different INMET weather stations were analyzed, located within the territorial limit of the nine states of Brazilian Northeast. Cluster analysis verified the formation of four distinct groups, with similar precipitation patterns in the regions within the groups as also observed in the principal component analysis. The pattern and/or spatial-temporal variability of rainfall in the municipalities analyzed was shown to be intimately associated with the conditions of the year and climatic anomalies stations, and the factors of land use and occupation, altitude and relief conditions, such as favoring the formation and stability of minor or major rain in the Brazilian Northeast. Multivariate cluster and principal component analysis identified rainfall patterns and similarities of groups, in the different states of Northeastern Brazil between the years 1995 and 2016.Keywords: multivariate analysis, climate change, semiarid, regional climate patterns.

There are currently 760 reptile species known in Brazil, from which about 70 are amphisbaenians with 25 species recorded in the Brazilian northeast (Vanzolini 2002; Gomes & Maciel 2012; Costa & Bérnils, 2014; Roberto et al., 2014). Leposternon polystegum Duméril, is a widespread species distributed in the Amazon, Atlantic Forest, Cerrado, and Caatinga biomes (Porto et al., 2000; Ribeiro et al., 2011). The diet is composed mainly by ants, termites, and coleopteran larvae (Barros-Filho & Valverde, 1996; Gomes et al., 2009).

In recent years, wind power in Brazil has emerged as an alternative to diversify the country′s energy mix and minimize the emission of pollutants derived from fossil fuels. The state of Rio Grande do Norte, in the Brazilian Northeast, has considerable potential for the generation of wind energy due to the occurrence of strong winds in many areas along the coast and in the interior of the state, in places with higher altitudes. However, wind energy, despite being considered clean and renewable, can cause environmental impacts in those places. Thus, the present study analyzed the perception of environmental impacts caused by the installation of wind farms in the agricultural areas of Northeast Brazil. The study was carried out in the municipality of Serra do Mel, in the western region of the state of Rio Grande do Norte, based on a survey of local farmers. The study concluded that farmers live without major problems and without apparent conflicts with wind farms but have little knowledge about the environmental impacts. In the perception of most farmers, there are few negative environmental impacts, and those that exist are barely noticed or still do not cause damage to most farmers in the region.

Melanoides tuberculata (Müller, 1774) was recorded during field surveys of the malacofauna of Território Vale do Guaribas in Piauí state, northeastern Brazil. Individuals were observed every month (June 2017–September 2018) in both lotic and lentic habitats. Considering that M. tuberculata has high reproductive and adaptative capacities besides being an intermediate host of digenetic trematodes, this invasive species is expected to be a threat to native biodiversity. Furthermore, it may become a serious environmental problem considering the multiple uses of the water bodies where it lives.

A presente pesquisa tem por objetivo descrever e contabilizar os casos oficiais reconhecidos pelo sistema integrado de informações sobre desastres e pelo Atlas Brasileiro de desastres naturais referente a ocorrências de eventos de movimento de massa e de erosão ocorridos na região Nordeste do Brasil, bem como analisar os principais métodos utilizados para avaliação destes fenômenos (técnicas de campo, laboratório e geoprocessamento). Conforme a análise dos dados, foi verificado que os estados de Pernambuco e da Bahia apresentaram o maior número de ocorrências destes processos na região Nordeste, estando esse fato relacionado as condições físicas-naturais e as formas de uso da terra. Em termos metodológicos, é predominante no nordeste brasileiro a utilização de metodologias analíticas com a finalidade de identificação de áreas de risco de deslizamentos, considerando-se os condicionantes naturais e antrópicos.Palavras–chave: Dinâmicas Superficiais, movimentos de massa, processos erosivos, Nordeste do Brasil.Abstract The present research aims to describe and account for official cases recognized by the integrated system of information on disasters and the Brazilian atlas of natural disasters related to events of mass movement and erosion occurred in the Northeast region of Brazil, as well as to analyze the main methods used for the evaluation of these phenomena (field techniques, laboratory and geoprocessing). According to the analysis of the data, it was verified that the states of Pernambuco and Bahia present the largest number of mass movement and erosion occurrences in the Northeast, being this fact related to the physical-natural conditions and the forms of surface occupation. In methodological terms, it is verified that in the Brazilian Northeast the analytical methodology is widely used in order to identify areas of risk of landslides, taking into account the natural and anthropogenic conditions.Keywords: Surface dynamics, mass movements, erosion processes, northeastern Brazil.

Abstract A new species of Trichostrongyloidea (Nematoda: Heligmonellidae), Hassalstrongylus lauroi n. sp., is described from specimens collected from the small intestine of the rodent Hylaeamys seuanezi in the Atlantic Forest of northeastern Brazil (Igrapiúna, state of Bahia). The genus Hassalstrongylus includes 17 species, which parasitize rodents occurring in the Neotropical and Nearctic regions. It differs from the genus Stilestrongylus through its smaller number of ridges in the synlophe and through the size of the genital cone. The main taxonomic characteristics of this new species are the subsymmetrical caudal bursa of type 2-2-1, ray 8 branching out at the base of the dorsal trunk, right lobe smaller than the left, and rays 4 and 5 of robust nature. In addition, the ornamental ray 5 and the robustness of ray 4 on the male caudal bursa, along with the modification of the ridges of the posterior end of the female, allow us to consider the specimens found to be a new species.
