This article provides a quantitative description of flora specimens stored in the Jardim Botânico of Rio de Janeiro Herbarium that belongs to the Federal Conservation Units of Caatinga’s phytogeography domain. The Caatinga represents 11% of Brazilian territory and is, in South America, the largest and most biodiverse semi-arid tropical ecoregion, yet only 5% of its territory is covered by Federal Conservation Units, with few collections of flora samples. Thus, providing a georeferenced inventory of existing collections is essential for purposes of species distribution, environmental management and conservation. The aim of this data paper is to gauge, by means of geographic coordinates correction and retrieval of the flora specimens present in the RB Herbarium, the amount of specimen gatherings performed in the Federal Conservation Units belonging to the Caatinga domain. Currently, the RB data is publicly available online at several biodiversity portals, such as our institutional database JABOT, the Reflora Virtual Herbarium, the SiBBr and the GBIF portal (Lanna et al. 2019). However, a description of the dataset that belongs to the Federal Conservation Units of Caatinga’s phytogeography domain as a whole is not yet available in the literature.

Management And Conservation

This paper aims to analyze the environmental management and conservation dilemma in the SNUC categories, especially the Environmental Protection Area (APA), with emphasis on the Atlantic Forest and the Cerrado. Much of the area designated for Conservation Units (UCs) in the country has been decreed as APA, a category widely criticized by the literature for involving highly urbanized areas whose use for tourism, farming, and mining hinder the management and conservation. It is essential, in this context, to establish partnerships with owners, reevaluate the proliferation of APAs, promote forest connectivity and prioritize critical Environmental Education in participatory management to resolve conflicts and stimulate conservation of natural resources.

Pokémon Go

Pokémon Go is the most popular location-based game worldwide. As a location-based game, Pokémon Go’s gameplay is connected to networked urban mobility. However, urban mobility differs significantly around the world. Large metropoles in South America and Africa, for example, experience ingrained social, cultural, and economic inequalities. With this in mind, we interviewed Pokémon Go players in two Global South cities, Rio de Janeiro (Brazil) and Nairobi (Kenya), to understand how players navigate urban spaces not only based on gameplay but with broader concerns for safety. Our findings reveal that players negotiate their urban mobilities based on perceptions of risk and safety, choosing how to move around and avoiding areas known for violence and theft. These findings are relevant for understanding the social and political aspects of networked urban spaces as well as for investigating games as venues through which we can understand ordinary life, racial, gender, and socioeconomic inequalities.

The Impact

Abstract Climatic and environmental changes, as well as human action, have been cited as potential causes for the extinction of megafauna in South America at the end of the Pleistocene. Among megamammals lineages with Holarctic origin, only horses and proboscideans went extinct in South America during this period. This study aims to understand how the spatial extent of habitats suitable for Equus neogeus and Notiomastodon platensis changed between the last glacial maximum (LGM) and the middle Holocene in order to determine the impact that climatic and environmental changes had on these taxa. We used species distribution modeling to estimate their potential extent on the continent and found that both species occupied arid and semiarid open lands during the LGM, mainly in the Pampean region of Argentina, southern and northeastern Brazil, and parts of the Andes. However, when climate conditions changed from dry and cold during the LGM to humid and warm during the middle Holocene, the areas suitable for these taxa were reduced dramatically. These results support the hypothesis that climatic changes were a driving cause of extinction of these megamammals in South America, although we cannot rule out the impact of human actions or other potential causes for their extinction.

Scinax hayii was described in 1909 from the municipality of Petrópolis, State of Rio de Janeiro, Brazil. Morphological variation and advertisement calls have been previously reported for other populations across the species distribution (Lutz 1973; Heyer et al. 1990; Cardoso & Andrade 1991; Pombal et al. 1995; Magrini et al. 2011; Abrunhosa et al. 2014). However, no information on calls are available from specimens recorded at the type locality, preventing the correct characterization of the species (Magrini et al. 2011). Here we describe the advertisement call and a second call type of S. hayii from Petrópolis, as a contribution towards a better understanding of the taxonomy of this species.

The integration or co-application of traditional knowledge and scientific knowledge has been the subject of considerable research and discussion (see Johannes 1981; Johnson 1992; Stevenson 1996; McDonald et al. 1997; Huntington et al. 1999, 2002), with emphasis on various specific topics including environmental management and conservation (see Freeman & Carbyn 1988; Ferguson & Messier 1997; Ford & Martinez 2000; Usher 2000; Albert 2001). In most cases, examples of successful integration compare traditional and scientific observations at similar spatial scales to increase confidence in understanding or to fill gaps that appear from either perspective. We present a different approach to integration, emphasizing complementarity rather than concordance in spatial perspective, using two migratory species as examples.

ABSTRACT: The objective of this study was to evaluate the agronomic efficiency of intercropping combinations of carrot and arugula at different population densities in bicropping in the semi-arid conditions of the Brazilian Northeast. The study was conducted at the "Rafael Fernandes" Experimental Farm of the Universidade Federal Rural do Semi-Árido (UFERSA) during the period September 2011 to February 2012. The experimental design was of randomized complete blocks with treatments arranged in a 4 x 4 factorial scheme with four replications. The combinations were four population densities of carrot (40, 60, 80 and 100% of the recommended population in sole crop - RPSC) with four population densities of arugula (40, 60, 80 and 100% of the RPSC). The recommended population densities for sole crops of carrot and arugula are 500,000 and 1,000,000 plants per hectare, respectively. All treatments were fertilized with hairy woodrose (Merremia aegyptia L.), a spontaneous species of the Caatinga biome. The highest agronomic efficiency of carrot intercropped with arugula in bicropping was achieved in the combination of 40% of RPSC for the carrot and 100% of RPSC for the arugula. The commercial maximum yield (33.74 t ha-1) of carrot roots and the maximum yields of arugula green mass (8.06 and 2.67 t ha-1) in both cultivations were also obtained in the combination of population densities of 40% of RPSC for carrot and 100% of RPSC for arugula.
