Brazil has a fundamental role in amphibian conservation, harboring the highest amphibian species richness in the world and a large number of endemics. Here, we present an overview of the Brazilian Amphibian Conservation Action Plan (BACAP), which is still being developed by Brazilian herpetologists. Basic research - particularly species inventories, taxonomic revisions and the collection of field data - are urgently needed to guide amphibian conservation in the country. Documentation and monitoring of amphibian richness has improved, at least at regional scales. Lists of threatened species are regularly updated, efforts to standardize field work protocols are being attempted and captive breeding is being considered as a research and educational tool. We also present a short history of the BACAP, identify some of the challenges tied to its implementation, and review a few but important recent achievements. © ISSCA 2012. Source

From 2005 to 2009, 147 ticks found on 32 wild animals from or referred to two zoobotanical parks (Parque Zoobotânico Arruda Câmara and Parque Estadual Dois Irmãos) located in northeastern Brazil were identified. Ticks found on two veterinarians working in one of the parks (i. e., Parque Estadual Dois Irmãos), after return from forested areas within the park's territory, were also identified. The following tick-host associations were recorded: Amblyomma fuscum Neumann on Boa constrictor L.; Amblyomma longirostre Koch on Ramphastos vitellinus ariel Vigors and Coendou prehensilis (L.); Amblyommavarium Koch on Bradypus variegates Schinz; Amblyomma rotundatum Koch on Chelonoidis carbonaria (Spix), Chelonoidis denticulata (L.), Micrurus ibiboboca (Merrem), Python molurus bivittatus Kuhl, Iguana iguana (L.) and B. variegatus; Amblyomma nodosum Neumann on Myrmecophaga tridactyla L. and Tamandua tetradactyla (L.); and Rhipicephalus sanguineus (Latreille) on Nasua nasua (L.). The ticks found on the veterinarians were identified as nine Amblyomma larvae. The presence of Am. nodosum in Pernambuco and Am. rotundatum and Am. varium in Paraíba is recorded for the first time and the occurrence of Am. longirostre in Pernambuco is confirmed. Ramphastos vitellinus ariel is a new host record for Am. longirostre whereas M. ibiboboca and B. variegatus are new host records for Am. rotundatum. Finally, the human parasitism by Amblyomma ticks is reported for the first time in Pernambuco, highlighting the potential of tick-borne pathogen transmission in this state. © Springer Science+Business Media B.V. 2009.

In this study was used two strains of marine-derived fungi (Penicillium citrinum CBMA1186 and Trichoderma sp. CBMAI 932) and two strains of terrestrial fungi (Aspergillus sp. FPZSP 146 and Aspergillus sp. FPZSP 152) to biotransformation bis-α,β-unsaturated ketones 1-. 2 to their corresponding 1,5-diphenylpentan-3-one (1a), (E)-1,5-diphenylpent-1-en-3-one (1b), 1,5-diphenylpentan-3-ol (1c), (E)-1,5-diphenylpent-1-en-3-ol (1d), 1,5-bis(4-methoxyphenyl)pentan-3-one (2a), (E)-1,5-bis(4-methoxyphenyl)pent-1-en-3-one (2b) and 1,5-bis(4-methoxyphenyl)pentan-3-ol (2c). The products were obtained in up to 84% conversion employing cultural broth and whole mycelia of mentioned fungi. © 2015 Elsevier Ltd. Source

Composting operations are a rich source for prospection of biomass degradation enzymes. We have analyzed the microbiomes of two composting samples collected in a facility inside the São Paulo Zoo Park, in Brazil. All organic waste produced in the park is processed in this facility, at a rate of four tons/day. Total DNA was extracted and sequenced with Roche/454 technology, generating about 3 million reads per sample. To our knowledge this work is the first report of a composting whole-microbial community using high-throughput sequencing and analysis. The phylogenetic profiles of the two microbiomes analyzed are quite different, with a clear dominance of members of the Lactobacillus genus in one of them. We found a general agreement of the distribution of functional categories in the Zoo compost metagenomes compared with seven selected public metagenomes of biomass deconstruction environments, indicating the potential for different bacterial communities to provide alternative mechanisms for the same functional purposes. Our results indicate that biomass degradation in this composting process, including deconstruction of recalcitrant lignocellulose, is fully performed by bacterial enzymes, most likely by members of the Clostridiales and Actinomycetales orders. © 2013 Martins et al.

This study presents the electrocardiogram findings from 97 captive tufted capuchin monkeys (Cebus apella) at the São Paulo Zoo (São Paulo, Brazil) while under ketamine anesthesia. The results did not differ greatly from data of domestic carnivores or other studied primate species. The most common rhythm recorded was normal sinus rhythm, followed by normal sinus rhythm with wandering pacemaker. Electrical axis varied from 0°to-150°but was most commonly between +60and +90°. QRS complexes were predominantly positive in leads DI, DII, DIII, and AVF. These findings allow for the recognition of abnormal rhythms in these primate species and can contribute to future investigations into the cardiovascular diseases routinely diagnosed in primates and humans. © 2012 American Association of Zoo Veterinarians.
