Planejamento do Turismo a partir da Perspectiva Actor-Centered Power no Parque Estadual da Ilha Grande, Rio de Janeiro, Brasil

Usualmente, o planejamento do turismo no Brasil segue a perspectiva normativa em sua execução. Este estudo propõe integrar a perspectiva actor-centered power ao planejamento a fim de elucidar quais são os atores sociais mais poderosos e quais são seus interesses no desenvolvimento turístico. Tal perspectiva é possível por meio da identificação desses atores e de sua relação com a coerção, a informação dominante e incentivos e desincentivos, categorias derivadas das abordagens de poder desenvolvidas por Krott. Para cumprir o objetivo proposto, realizou-se entrevistas mediante a técnica bola de neve. A hipótese de pesquisa é que o planejamento do turismo no Parque Estadual da Ilha Grande (Rio de Janeiro, Brasil) é direcionado pelos interesses dos atores sociais mais poderosos. Os resultados confirmam tal hipótese e demostram que há grande conflito de interesses entre ONGs, governo e administração da Unidade de Conservação.Usually, tourism planning in Brazil follows the normative perspective in its implementation. This study proposes to integrate the actor-centered power perspective with planning in order to elucidate which are the most powerful social actors and what are their interests in tourism development. Such perspective is enabled through the identification of these actors and their relation with coercion, dominant information, and incentives and disincentives, categories derived from the approaches to power developed by Krott. In order to achieve the objective, interviews were conducted by employing the snowball technique. The research hypothesis is that tourism planning in the Ilha Grande State Park (Rio de Janeiro, Brazil) is directed by the interests of the most powerful social actors. The results confirm such hypothesis and show that there is great conflict of interests between NGOs, Government, and the administration of the Conservation Unit.Por lo general, el planeamiento del turismo en Brasil sigue la perspectiva normativa en su aplicación. Este estudio propone la integración de la perspectiva actor-centered power (Krott et al., 2014) a la planificación para dilucidar cuales son los actores sociales más poderosos y cuáles son sus intereses en el desarrollo del turismo. Tal perspectiva es posible a través de la identificación de estos actores y de su relación con la coacción, la información dominante y los incentivos y desincentivos, categorías derivadas de los enfoques del poder desarrollados por Krott (2005). Para cumplir con el objetivo propuesto, se llevó a cabo entrevistas realizadas por medio de la técnica bola de nieve. La hipótesis de la investigación es que la ordenación del turismo en el Parque Estatal de Ilha Grande (Río de Janeiro, Brasil) es dirigida por los intereses de los actores sociales más poderosos. Los resultados confirman esta hipótesis y demuestran que hay un gran conflicto de intereses entre las ONGs, gobierno y administración de la Unidad de Conservación

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora

Characterisation of microbial attack on archaeological bone

As part of an EU funded project to investigate the factors influencing bone preservation in the archaeological record, more than 250 bones from 41 archaeological sites in five countries spanning four climatic regions were studied for diagenetic alteration. Sites were selected to cover a range of environmental conditions and archaeological contexts. Microscopic and physical (mercury intrusion porosimetry) analyses of these bones revealed that the majority (68%) had suffered microbial attack. Furthermore, significant differences were found between animal and human bone in both the state of preservation and the type of microbial attack present. These differences in preservation might result from differences in early taphonomy of the bones. © 2003 Elsevier Science Ltd. All rights reserved
