Two new species of Cnemidophorus (Squamata: Teiidae) from the Caatinga, Northwest Brazil

Two syntopic species of Cnemidophorus are described from the Caatingas of the Parque Nacional da Serra das Confusoes (PNSC), located in the Southwestern region of the state of Piaui in Brazil. Both species are assigned to the ocellifer group, differing from all other members of the group by their distinct color pattern and lepidosis. Besides these differences, both new species share a number of particular features with other members of the group. One of them, C. venetacaudus, shares with C. abaetensis and C. littoralis the presence of spurs in the heels of males, six supraciliar scales, a high number of femoral pores (from 21-45), a row of enlarged scales in the dorsal region of the arm, 8-10 rows of ventral scales, and a bright bluish-green tail, while the other species, C. confusionibus, shares with C. ocellifer, C. mumbuca, and C. jalapensis a low number of femoral pores, enlarged scales in the temporal region (posterior to third subocular), 5 supraciliar scales, and 6-8 rows of ventral scales. Based on these comparisons, we suggest that the ocellifer group is more complex than previously admitted, being composed by at least two morphologically recognizable species subgroups.

A new species of Vriesea Lindl. (Bromeliaceae, Tillandsioideae) from Serra da Canastra, Minas Gerais State, Brazil

A new species of Vriesea Lindl. belonging to section Xiphion (E. Morren) E. Morren ex Mez. - V. sanfranciscana Versieux & Wand.- is described and illustrated. The species is only known to occur in the Serra da Canastra National Park, located in the southwestern Minas Gerais, Brazil, and is morphologically related to V. atropurpurea Silveira from serra do Cipo, Espinhaco range.

A new species of Dendrophryniscus (Amphibia, Anura, Bufonidae) from the Atlantic Rainforest of southern Bahia, Brazil

A new species of the tree toad genus Dendrophryniscus is described from a rainforest habitat at Parque Nacional de Serra das Lontras, municipality of Arataca, southern Bahia, Brazil. Dendrophryniscus oreites sp. nov. is related to the Atlantic forest brevipollicatus group by hand morphology, skin texture, ventral coloration and bromelicolous habits. The new species differs from related species by having a larger size, warty skin, inner finger reduced with presence of a dark nuptial pad in males, and a yellowish coloration with discrete dorsal pattern. This discovery highlights the importance of southern Bahia in terms of conservation, and for our understanding of the evolution of the frog diversity within the Atlantic Rainforest.

Loxosceles chapadensis (Araneae: Sicariidae): a new recluse spider species of the gaucho group from Brazil

A new species of the medically important recluse spider genus Loxosceles Heinecken & Lowe 1832 is described from the State of Bahia, Brazil. The species occurs between rocks and crevices, as well as in and around man-made structures. The new species belongs to the gaucho group, as evidenced by the spermathecal shape and color pattern. The presence of a long male palpal tibia is unusual in the gaucho group; thus, the inclusion of the new species in this group is discussed.

Systematic revision and cladistic analysis of the Brazilian subfamily Sodreaninae (Opiliones: Gonyleptidae)

Sodreaninae is reviewed and all ten species are combined under its type genus, Sodreana Mello-Leitao, 1922, according to a cladistic analysis of morphological characters, which revealed a pectinate pattern of clades. The subfamily is endemic to the Brazilian Atlantic rainforest from Santa Catarina state to Rio de Janeiro state. Sodreana is herein considered a senior synonym of Stygnobates Mello-Leitao, 1927, Zortalia Mello-Leitao, 1936, Gertia B. Soares & H. Soares, 1946 and Annampheres H. Soares, 1979. The following new combinations are proposed: Sodreana barbiellinii (Mello-Leitao, 1927), Sodreana hatschbachi (B. Soares & H. Soares, 1946), Sodreana inscripta (Mello-Leitao, 1939), Sodreana leprevosti (B. Soares & H. Soares, 1947b), Sodreana bicalcarata (Mello-Leitao, 1936). Sodreana granulata (Mello-Leitao, 1937) is revalidated from the synonymy of Sodreana sodreana Mello-Leitao, 1922. Three new species are described: Sodreana glaucoi from Ilhabela and Boraceia, Sao Paulo state; S. curupira from Parque Nacional da Serra dos Orgaos, Rio de Janeiro state, and S. caipora from Ubatuba, Sao Paulo state. Sodreaninae species are restricted to forested areas and most occur in the southern part of the coastal Atlantic rainforest, one species occurs in interior Atlantic rainforest. The biogeographical analysis (Brooks Parsimony Analysis) resulted in a single and fully resolved most parsimonious tree with three main: components: northern (Bahia and Serra do Espinhaco), southern (Santa Catarina, Parana, Serra do Mar of Sao Paulo), and central (Espirito Santo, Serra da Bocaina, southern state of Rio de Janeiro, Serra dos Orgaos, Serra da Mantiqueira, Serra do Mar of Sao Paulo).

Governando os comuns ou para os comuns?: gestão de áreas protegidas e os arranjos institucionais da política ambiental no Estado de São Paulo

Desde o século XIX, quando foi instituído o primeiro parque nacional, a gestão de áreas protegidas foi evoluindo e se aprimorando, sendo um importante mecanismo para a conservação da biodiversidade e uma das ações de maior intervenção estatal. Neste sentido, esta dissertação apresenta uma análise dos arranjos institucionais da política ambiental que impactam o uso comum dos recursos naturais por populações residentes do Parque Estadual da Serra do Mar. Para esta discussão, são analisados: o embate teórico entre ambientalismo e socioambientalismo; a problemática do uso de acesso comum, associada a necessidade, ou não, de intervenção governamental; os programas e ações do Governo do Estado de São Paulo para a consolidação das unidades de conservação de proteção integral; e as variáveis que compõe os arranjos institucionais da política ambiental dos casos avaliados, na Cota 400 e Água Fria, no município de Cubatão. Face aos arranjos institucionais da política ambiental para gestão de áreas protegidas, esta dissertação busca compreender qual a melhor situação para a conservação dos recursos naturais, com estudos aplicados a luz do modelo proposto por Elinor Ostrom. A análise dos casos permitiu verificar uma performance institucional frágil da comunidade para o uso sustentável dos recursos de acesso comum.

A descoberta do meio ambiente: Itatiaia e a política brasileira de parques nacionais

O presente trabalho tem por objetivo compreender como se deu a política de criação de parques nacionais no Brasil. Para tanto, faremos à luz da história uma retrospectiva das atividades econômicas que mais culminaram em prejuízos ambientais no Brasil assim como um sucinto levantamento dos instrumentos estabelecidos, cada um à sua época, enquanto responsáveis pela redução ou mesmo pela retratação destes danos. Dentre estes instrumentos citamos os parques nacionais, uma das várias qualidades de unidades de conservação estabelecidas enquanto metodologia responsável por diminuir o avanço exploratório sobre um bioma específico. Concluiremos essa dissertação com uma análise dos motivos que justificaram a inserção do primeiro parque nacional brasileiro na região Serra da Mantiqueira. O Parque Nacional do Itatiaia, criado durante o primeiro governo do Presidente Vargas e estrategicamente localizado entre as maiores cidades do país apresentava-se ao mesmo tempo como um espaço de preservação ambiental e de deleite de veranistas, servindo à salvaguarda biota e ao lazer. Foi modelo para as outras seis dezenas de parques nacionais que fazem parte de nossas unidades de conservação e continua chamando a atenção pela beleza cênica e pela diversidade ambiental que protege.

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.

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

Diversidade de Seirini (Collembola, Arthropleona, Entomobryidae), em áreas úmidas da caatinga

The family Entomobryidae is one of the most diverse families of Collembola in Northeast Brazil. Data on its diversity may be considered undervalued due to low collection efforts in the region. In this study, five areas in the Northeast region were sampled, to evaluate the species richness of this family. The study was done in the Serra da Jibóia, Santa Terezinha municipality, Bahia; Serra das Confusões, Caracol municipality, Piauí; Chapada do Araripe, Crato municipality, Ceará; Mata do Pau-Ferro, Areia municipality, Paraíba and Parque Nacional de Ubajara, Ubajara municipality, Ceará, all considered humid areas of Caatinga. Collections were made using pitfall traps and entomological aspirators. All the collected material was screened, mounted on slides, identified and, finally, the descriptions of some of the new species encountered were made. A total of 48 Entomobryidae species belonging to nine genera were recorded and 27 of these were new to science, representing a percentage of 56.25% of the total. A new record for Brazil was identified and several new records were made to the States. Seira was the genus with wider distribution and it was the only one found in all areas and the most representative with the highest number of recorded species (26). This result was expected, because individuals of the genus Seira have a good adaptability to semi-arid environments, a fact that has already been proven in previous research. Seven new species of Seira were described. A dichotomous key to genera and species of Seirini from Brazil was drafted. This work demonstrates the great potential of Entomobryidae and Seirini in the Northeast, despite having been held in very restricted areas, obtained important results for the knowledge of fauna of the group

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
