Abstract One group of Ateles chamek (Humboldt 1812) was observed during 12 days in the Vila Bela da Santíssima Trindade municipality, in the state of Mato Grosso. During that time fecal samples (n=10) were collected and molecular sequencing was used to confirm species identification. The results suggest that the particular pattern of facial hair color observed in this group may be used for differentiation from other sub-populations; however, a deeper study is required for confirmation of these results. This record represents the most southwestern observation of this species, and increases the geographic distribution of A. chamek for about 16 km into the southern Brazilian Amazon. Taking into consideration the threatened status of this species of monkey, and that this region is under constant intensive deforestation, it is important to highlight that ecological studies and conservation activities require urgent development.

Abstract Accurate identification of predator species is a critical requirement to investigate their diet using faecal samples. We used non-invasive sampling and two methods of predator identification to investigate the diets of sympatric carnivores in a highly deforested region of the Brazilian Amazon. Of 108 scats, 81 could be identified at the species level using DNA sequencing and/or trichology. The former performed better than the latter (81.5% vs. 54.3% of the identified samples), and results were quite congruent (89.7% concordance in the 29 samples that could be assessed with both approaches). Nine species were identified, out of which four (crab-eating fox, ocelot, puma and jaguar) presented a sufficient number of samples to allow dietary analyses. The crab-eating fox was the most generalist (BA=0.92); ocelots focused on small- to medium-sized prey; pumas fed mostly on medium-sized items; and jaguars mostly targeted large-sized prey. A considerable overlap was observed between ocelots and pumas in all estimations (O=0.47–0.83). The presence of jaguars in the same region could be driving pumas to select medium- and small-sized prey. The results of this study highlight the importance of reliable predator identification and the need for in-depth ecological studies in areas where carnivore species are sympatric.

Abstract: We report range extensions for three species of Amazonian erethizontids, Coendou bicolor, C. ichillus, and C. nycthemera. We record C. ichillus for the first time in Brazil, from Rio Japurá, state of Amazonas. We record C. bicolor for the first time in the state of Amazonas, which represents a range extension of approximately 905 km. We also extend the occurrence of C. nycthemera 620 km to the south into Mato Grosso state. All records are based on museum specimens, highlighting the importance of scientific collections as biodiversity databases and emphasizing the lack of research on Amazonian porcupines.

O artigo apresenta a metodologia criada e experimentada para o planejamento participativo de produtos turísticos em terras indígenas e os principais resultados de sua aplicação. O turismo foi identificado pelos indígenas como uma atividade econômica alternativa ao desmatamento durante o desenvolvimento dos Planos de Gestão Territorial na Terra Indígena Sete de Setembro (RO/MT) do Povo Paiter-Suruí e na Terra Indígena Nove de Janeiro (AM) do Povo Parintintin. Com o objetivo de propor princípios e procedimentos para visitação turística ordenada, o processo de planejamento participativo buscou garantir que, além de ser uma alternativa economicamente viável, o turismo seja também um instrumento de resgate e valorização cultural, que respeita a diversidade, mitos, cosmovisão e modo de vida atual indígena. A metodologia utilizada para o desenvolvimento dos produtos turísticos envolveu uma série de atividades como oficinas de turismo, intercâmbio, inventários, planejamento de roteiros, propostas de infraestrutura e estudos de mercado específicos para cada uma das etnias. Como resultado obteve-se propostas de operações turísticas viáveis e adequadas ao mercado, mas que também atendem às expectativas e possibilidades dos indígenas. Estas experiências também resultaram em uma metodologia de desenvolvimento de produtos turísticos estruturada na relação entre o saber científico e tradicional, portanto em uma dinâmica participativa, que poderá contribuir para a regulamentação da atividade turística em Terras Indígenas, adequando-se à Política Nacional de Gestão Ambiental e Territorial Indígena. Participative development of tourism products in indigenous lands located in the brazilian Amazon ABSTRACT The article presents the methodology created and experimented for participative planning applied in the development of tourism products in indigenous lands and the principal results obtained. During the development process of the Territorial Management Plans for the Sete de Setembro Indigenous Land, belonging to Paiter-Suruí People (States of Roraima and Mato Grosso) and for the Nove de Janeiro Indigenous Land, belonging to Parintintin People (Amazonas State), tourism was identified by the indigenous peoples themselves as being a viable alternative economic activity to deforestation. With the aim of proposing standards and procedures for organized guided tours, this project sought to guarantee that, in addition to representing a viable economic alternative, tourism should also function as a means of valuing and reviving traditional indigenous culture, in a way that respects the diversity, mythology, worldview and the way of life of tribal peoples today. The methodology of development of tourism products involved a series of activities, such as tourism workshops, interchange, register, planning tourist routes, proposals related to infrastructure and market studies specifically designed for each ethnic group. The results of this work are proposes of viable tourism operations, those also fulfils the expectations and possibilities of the Indigenous peoples themselves. These experiences resulted in a methodology of developing tourism products based on a relationship between scientific and traditional knowledge, consequently using a participative approach, which may be useful when regulating tourism activities in Tribal Lands, in accordance with Brazil’s National Policy for the Territorial and Environmental Management of Indigenous Lands. KEYWORDS: Tourism in Indigenous Lands; Participative Planning; Sustainability; Tourism Goods; Brazilian Amazon.

We present new distribution records for Topaza pella (Linnaeus, 1758) in the southern reaches of the Amazon Basin in Brazil. The two new localities presented for the species elucidate its range in southern Pará and northern Mato Grosso states, and in consideration of recent records elsewhere south of the Amazon River, suggest that the species is widely distributed across suitable habitat throughout the Brazilian Amazon.

ABSTRACT A new species of Sarcofahrtiopsis Hall, 1933, S. terezinhae sp. nov., is described based on male specimens collected in traps baited with rotting crabs in a mangrove forest in the state of Pará, eastern Brazilian Amazon. This species differs from congeneric species in having vesica with a row of toe-like projections. We provide a key to the species of the genus.

Objective. This study was performed to assess neurosurgery patients’ preference for surgeon’s attire and appearance in the hospital. Methods. A total of 100 patients were investigated using a questionnaire comprising 13 questions. We first asked patients about neurosurgeon’s appearance including accessories, hair color, mustache, and beard. Then, based on their preferences, they were asked to rank a series of photographs which illustrated a variety of neurosurgeon attires worn by a doctor. Results. Professional attire with white coat was the most ideal for patients compared to any other attire (preference scale 5.28 ± 1.24), and there was a significant preference gap between wearing a white coat and not wearing a white coat (p <0.01). Patients expressed a preference for neurosurgeon’s shoes (30%) but the majority of the respondents answered that it does not matter which shoes their neurosurgeon wears (43%). Furthermore, the patients did not have any preferences regarding accessories, dyeing, and mustache or beard (58%, 67%, and 51%, respectively), and they did not have negative view towards doctor wearing accessories (71.7%) and growing mustache or beard (71.6%). Conclusion. The patients in this study preferred professional attire along with a white coat compared to any other form of outfit. This result is similar to those of many other studies conducted in other departments or other countries. However, patients did not have a strong negative view on accessories, dyeing, and facial hair. With regard to medical training, patients did not show a preference for their neurosurgeon’s educational background.
