This dataset presents the macrobenthic species occurrence frequency in four coastal intertidal reefs environment of Paraiba state Brazil. The species were classified in bioindicators groups based in morpho-anatomical, physiological and ecological characteristics. In the dry and wet season in each reef, the sampling units were randomly positioned and photographed inside a circular area with a 10 m radius. Thirty points were plotted over photos to quantify the percentage of species occurrence frequency. Taxons hard to identify by photo were grouped in a unique category. Currently, macrobenthic species are used as bioindicators of the local state of conservation by managing agencies. The population ecology monitoring of macrobenthic species with bioindicator potential is useful to recognize seasonal environmental patterns or local anthropic impactful. The research article on these data [1] will be published in the journal Ocean and Coastal Management for some interpretive insights. Title: Evaluation of the conservation status and monitoring proposal for the coastal reefs of Paraíba, Brazil: bioindication as an environmental management tool.

The urbanization process has led to significant changes in the landscape, shifting the epidemiological profile of the visceral leishmaniasis (VL) in Brazil. Dogs are considered the main urban reservoir of VL, whose infections precede cases in humans. In order to understand the socio-environmental determinants associated with canine visceral leishmaniasis (CVL), we conducted a spatial analysis of CVL cases in northeastern Brazil from 2013 to 2015, georeferencing 3288 domiciled dogs. We used linear mixed models to understand the ecoepidemiological determinants of CVL spatial relative risk (CVL SRR). Our findings indicate heterogeneity in CVL distribution, with 1 km diameter clusters potentially connected within an estimated 4.9 km diameter by the Ripley-K statistic. In our best-fit model, the CVL SRR was positively correlated with the proportion of households with literate heads, with trees, and with open sewage, but negatively correlated with vegetation phenology and mean income of the census sector. Here, we discuss the potential maintenance source of urban CVL clusters on a One Health framework. These findings highlight the complex interplay of socioeconomic and environmental factors in shaping the spatial distribution of CVL.

Southern house wren Troglodytes musculus Naumann, 1823 (Passeriformes: Troglodytidae) is widely distributed in Brazil, occurring on the edges of forests and urban areas, considerable a passeriform usually found in antropized landscape. Birds use vocal signs in diverse activities during the circadian cycle (eg.: in reproduction, territorial defense, alert of predators and competitors, individual recognition, etc), employing vocal signs under energetic balance for development of diary activities. The aim of this study was to evaluate the diary activity period of T. musculus through their vocalizations. The sampling were made during two days in edges of Atlantic Forest fragments in João Pessoa, State of Paraíba, Brazil. Using the method of playback, vocal response of Southern house wren was measured in six periods for each day: H1 (5 h-7 h), H2 (7 h-9 h), H3 (9 h-11 h), H4 (11 h-13 h), H5 (13 h-15 h) and H6 (15 h-17 h). Differences among the periods was tested through of Kruskall-Wallis test, and Mann-Whitney test with Bonferroni’s corrections. In order to separate the periods groups, was applied Cluster test and non-Metric Multidimensional Scaling. Were registered 2,421 vocalizations, which 2,229 in morning (H1 to H3) and 122 (H4 to H6) in the afternoon period. Results indicated there were differences among the diary activities period of T. musculus (p = 0.0008171), with early hours of morning (H1 and H2) did not differ between each other Received February 02, 2018 Accepted April 13, 2018 Released April 30, 2018 Full Text Article 0000-0001-9104-7418 Daniel Silva Lula Leite 0000-0002-0858-3269 Natan Diego Alves de Freitas 134 Leite et al. Braz. J. Biol. Sci., 2018, v. 5, No. 9, p. 133-141. (p = 0.183), however differing from the others. The H3 and H6 periods also not differ between each other (p = 0.784), but differing significantly from H4 and H5, that did not record no one vocalization (p = 1). Cluster analyses support these results, clustering: Group 1 (H1 and H2); Group 2 (H4 and H5) and Group 3 (H3 and H6). The periods with the highest frequencies of vocal sings (Group 1) showed the most favorable conditions to vocalize, be they microclimatic (better sound transmission due lowest wind intensity and air turbulence) or behaviors (females attraction, territorial invasion, etc.). On the other hand, non-recording of vocalizations of Group 2 suggest unfavorable periods to vocalize. In addition, Southern house wren concentrate their energetic reserves foraging in these periods. The intermediary records of Group 3 indicate that the periods H3 and H6 require an expensive energetic cost to vocalize due the lowest success in an effective communication. In that way, this present study suggest there was a pattern in diary activity period in Southern House Wren populations evaluated, with no overlap of activities, complementing the knowledge of the specie biology and behavior.

Sapajus flaviusou macaco-prego-galego foiredescoberta em 2006 e se encontra em Perigo de Extinção. Os parques zoológicos atuam na educação ambiental, conservação, manutenção e reprodução desses animais em cativeiro. Contudo, quais são os efeitos da presença humana sobre os macacos-pregos-gealegos em cativeiro? Este trabalho objetivou descrever e analisar as interações sociais das classes sexo-etárias de um grupo ex situ de S. flavius, de acordo com a presença e ausência de visitantes em um contexto de oferta alimentar no Parque Zoobotânico Arruda Câmara na Paraíba. Para isso, foram adaptados métodos desenvolvidos com populações de macaco-prego-galego in situ. Os comportamentos mais frequentes obtidos foram Vocalização(36,28%), Monopolização(14,46%), Estereotipia(13,16%) e Agonismo Antrópico(11,3%). O comportamento de Esfregar a Barbelanão ocorreu durante a coleta de dados, podendo indicar um possível aspecto cultural sobre tal interação e/ou alteração causada pelo cativeiro e pelas perturbações humanas.Na presença de visitantes as interações “Agonistas” (p < 0.01) eo “Repouso” (p < 0.05) diminuíram de modo significativo. Enquanto que o “Agonismo Antrópico” (p < 0.01) aumentou significativamente com a presença dos visitantes. Portanto, os macacos-pregos-galegos cativos sofreram alterações das interações sociais pelo estresse do cativeiro e também por perturbações causadaspela presença humana.
