Serosurvey for antibodies against Brucella abortus and Leptospira interrogans in pampas deer from Brazil

A survey for antibodies against Brucella abortus, and Leptospira interrogans was conducted on 17 pampas deer (Ozotocerus bezoarticus) from Pantanal Matogrossense (State of Mato Grosso do Sul, Brazil) and on 24 pampas deer from Parque Nacional de Emas (State of Goias, Brazil). Antibodies against B. abortus were detected by plate ag glutination, rose Bengal, and complement fixation tests, antibodies against Leptospira interrogans were detected by the microscopic agglutination test. All sera were negative for B. abortus antibodies and all deer sera from Parque Nacional de Emas were negative for L. interrogans antibodies. Four (24%) of 17 sera from Pantanal Matogrossense were positive for L. interrogans serovar (n = 2) hardjo, wolffi (n = 1) and mini (n = 1). While these diseases do not appear to be of major importance to the health status of Pampas deer, it appears that deer are reservoir for leptospirosis in one of the study areas.

A luta do Bispo Dom José de Medeiros Delgado por educação escolar para todos (Caicó-RN, 1941-1951)

The socioeducational program of actions developed by Dom José de Medeiros Delgado, first Bishop of Diocese of Caicó city in Rio Grande do Norte, from 1941 to 1951, is analyzed by the present work in a historical perspective, based upon the school culture refecence.Through this reference point, the general and peculiar school culture proper of catholic schools founded by Dom Delgado was learned.The schools are: the Ginásio Diocesano Seridoense (1942), the Escola Doméstica Popular Darci Vargas (1943, the Prevocacional School of Caicó (1944) and the Santo Cura d ars Seminar (1946). The socioeducational actions of Dom Delgado Bishop affected seven other towns surrounding Caicó. Places where catholic schools were founded and named after Escola do Pobre . In fight for schools for all social segments of city and rural natures, Dom Delgado founded four rural schools in the surroundings of Serra Negra, São João do Sabugi, Jardim do Seridó e Lagoa Nova. It is also part of his beneficial work the creation of rural cooperatives for the parents of the students from such schools

Desenvolvimento dos filhotes de atobas-de-pés-vermelhos (Sula sula) no aquipélego de Fernando de Noronha/PE

Parental care s costs increase with the time spent due to incapacity of parents give assistance to increasing offspring food s requirement. This parental care deficits is crucial to offspring s emancipation that involve abilities development to they survive independently. In this work we observe 16 Red-footed boobies chick (Sula sula) on different stages of development, at area of Parque Nacional Marinho of Fernando de Noronha s archipelago, from August to October of 2005. Our data show the parents presence decrease during chick development and an activity frequency modification, in move and fly, which suggest the emancipation s chick development. We observe also the action of Kleptoparasits and the influence with offspring parental care. Our data show consistency with the literature. However, we consider that studies carried through during the peak of the reproductive station can support the hypothesis of that the conflicts, together with the initial period of development of the flight, can be representative in terms of mortality of chicks for the studied species

Fungos gasteroides (Basidiomycota, Agaricomycetes) de três áreas de semiárido no Estado do Ceará, Brasil

Gasteroid fungi include several distinct lineages of basidiomycetes that were grouped by presenting some striking features in common like angiocarpic development and passive release of basidiospores. For a long period these fungi were accomodate in Gasteromycetes class. However, biochemistry and molecular studies showed the polyphyly of this group and curriently this class lies devoid of taxonomic value. These organisms influence the ecology of the various biomes, however, are poorly studied and knowledge of their diversity in neotropical ecosystems remains insufficient, despite studies that have been developed in recent years. The Brazilian semiarid region has many areas with an unexplored mycobiota. Ceará State has many areas of extreme biological importance and for this study three protected areas were chosen: Área de Proteção Ambiental da Serra da Ibiapaba, Parque Nacional de Ubajara and Área de Proteção Ambiental de Baturité. Therefore, the aim of this study was to inventory gasteroid fungi ocorring in these three areas in the semiarid region of Ceará. The expeditions, herborization and analysis of specimes were based in traditional methodology used to identify gasteroid fungi. Were identified 16 species belong to 5 families: Agaricaceae, Clathraceae, Geastraceae, Nidulariceae and Phallaceae. Morganella nuda Alfredo & Baseia is recorded for the second time in the world, Blumenavia angolensis (Welw. & Curr) Dring and Mutinus elegans (Mont.) E. Fisch. corresponds to a first record in the Brazilian Northeastern. Except for Abrachium floriforme (Baseia & Calonge) Baseia & T.S. Cabral and Geastrum lloydianum Rick, all remaining species are new records for Ceará, increasing the list of gasteroid fungi in the region of 3 for 17 species. Identified species were deposited in the collection of the Herbarium of Universidade Federal do Rio Grande do Norte. Although these areas have proved conducive to the study of gasteroid fungi, more efforts are still needed to increase knowledge of these fungi in the region

Interações socioculturais com a fauna silvestre em uma unidade de conservação na Amazônia: relações de gênero e geração

Este artigo descreve as interações socioculturalmente estabelecidas entre os moradores do rio Unini, Parque Nacional do Jaú, Amazônia central, com o conjunto da fauna silvestre local. Analisa a diversidade dessas interações e a reprodução das mesmas quando influenciadas por fatores de gênero e geração. Os procedimentos metodológicos adotados foram observação participativa e oficinas de grupos focais. Nessas oficinas, foram produzidas free-listings de animais silvestres relacionados a um determinado habitat. O grau de similaridade e dissimilaridade entre as listas foi analisado utilizando-se o Índice de Jaccard, ilustrado em dendrogramas. de maneira geral, as associações mentais entre elementos da fauna, habitat da floresta e nichos ecológicos que expressam as interações socioculturais dos indivíduos com os animais silvestres são bastante similares entre os membros da comunidade. No entanto, os efeitos de geração e de gênero são perceptíveis. A reprodução dessas interações perpassa pela questão do habitus, que estrutura o processo de socialização das interações culturais com a fauna local.

Redescription and reevaluation of the generic status of Leptodactylus dantasi (Amphibia, Anura, Leptodactylidae) and description of its unusual advertisement call

Leptodactylus dantasi Bokermann is redescribed from adult specimens collected in Parque Nacional da Serra do Divisor, State of Acre, Brazil, near the border between the Brazilian state of Acre and Peru. We propose the inclusion of this species in the genus Hydrolaetare. A new diagnostic character observed for the genus is the presence of fringes of fingers, and fringes and webbing of toes, finely serrate; the serrate edge of the fringe and webbing can be keratinized in males, females, and subadults. Hydrolaetare dantasi (Bokermann) is characterized by robust body and limbs, a broad and depressed head, slightly shorter than wide, and long, pointed and basally webbed toes. Hydrolaetare dantasi differs from the only other species in this genus, Hydrolaetare schmidti (Cochran and Goin), mainly by having toes webbed basally (fully webbed in H. schmidti). The advertisement call of H. dantasi is composed of two components; an initial note produced by the impact of the vocal sac against the ground and a second note corresponding to a long whistle of ascending frequency. The initial note is a percussive sound and represents an unusual form of sound emission in anurans; the second note is a vocalization.
