The genus Hemidactylus Oken, 1817 has cosmopolite distribution, with three species occurring in Brazil, two of them native, H. brasilianus and H. agrius, and one exotic, H. mabouia. Considering the studies about ecology of lizards conducted in the Ecological Station of the Seridó, from 2001 to 2011, this study aimed (1) to re-evaluate the occurrence of the species of Hemidactylus in this ESEC; (2) to analyze ecological and biological aspects of the H. agrius population; and (3) to investigate the current and potential distribution of the native species of the genus in northeastern Brazil, analyzing the suitability of ESEC to this taxon. For the first two objectives, a sampling area consisting of five transects of 200 x 20 m, was inspected in alternating daily shifts for three consecutive days, from August 2012 to August 2013. For the latter objective, occurrence points of H. agrius and H. brasilianus from literature and from the database of Herpetological Collections of the UFRN and the UNICAMP were consulted to build predictive maps via the Maximum Entropy algorithm (MaxEnt). In ESEC Seridó, 62 H. agrius individuals were collected (25 females, 18 males and 19 juveniles), and two neonates were obtained from a communal nest incubated in the laboratory. No record was made for the other two species of the genus. Hemidactylus agrius demonstrated to be a nocturnal species specialized in habitats with rocky outcrops; but this species is generalist regarding microhabitat use. In the population studied, females had an average body length greater than males, and showed higher frequencies of caudal autotomy. Regarding diet, H. agrius is a moderately generalist species that consumes arthropods, especially insect larvae, Isoptera and Araneae; and vertebrates, with a case of cannibalism registered in the population. With respect to seasonal differences, only the number of food items ingested differed between seasons. The diet was similar between sexes, but ontogenetic differences were recorded for the total volume and maximum length of the food items. Significant relationships were found between lizard body/head size measurements and the maximum length of prey consumed. Cases of polydactyly and tail bifurcation were recorded in the population, with frequencies of 1.6% and 3.1%, respectively. In relation xv to the occurrence points of the native species, 27 were identified, 14 for H. agrius and 13 for H. brasilianus. The first species presented restricted distribution, while the second showed a wide distribution. In both models generated, the ESEC Seridó area showed medium to high suitability. The results of this study confirm the absence of H. brasilianus and H. mabouia this ESEC, and reveal H. agrius as a dietary opportunist and cannibal species. Further, the results confirm the distribution patterns shown by native species of Hemidactylus, and point ESEC Seridó as an area of probable occurrence for the species of the genus, the establishing of H. brasilianus and H. mabouia are probably limited by biotic factors, a fact yet little understood

The Caatinga and Atlantic Forest exhibit great species richness, which can attend requirements for various uses. Considering the current level of degradation of vegetation in Rio Grande do Norte, and the increasing use of exotic species, it is urgent to perform actions for the conservation of these biomes. From this perspective, using native plant species in the urban forestry becomes an instrument for the conservation and enhancement of local biodiversity. In this context, the general objective of this study is to gather and provide information about the ornamental native tree species in the state in order to promote and disseminate their use in urban areas. Specific aims of this work are: (1) evaluate and verify the demand and maintenance costs of native and exotic urban forestry, comparatively, with data obtained in the state (Cap. 1); (2) Provide a ornamental native tree species list in the state, including species already widespread use and suggesting new elements with ornamental potential (Cap. 2); and (3) produce a guide of native tree species as a means of disseminating the results obtained in a way accessible to the society. Analysis of maintenance of urban trees was performed at the UFRN's Central Campus, and the ornamental native tree species survey was carried out through literature survey combined with expeditions to forest fragments in the state. As a result, it was obvious that the maintenance of native vegetation resulted in lower costs and least demand for services highlighting the visible advantage in using a afforestation with regionalized floristic composition. The survey of ornamental native tree species led to the selection of 95 species belonging to 30 families, 17 species (17.35%) occurring exclusively in the Caatinga, 27 species (25.55%) in the Atlantic Forest and more than half (55.10%) occurring in both biomes, which provides a good selection available for the composition of urban forestry, both for cities located in the area of Atlantic Forest (81 spp.) or for those located in the Caatinga (71 spp.). From these results, a guide for the recognition and cultivation of native ornamental trees was prepared, consisting in the initial step in the enhancement of existing floristic potential value with the aim to assist in the development of a regionalized perspective of urban environmental management in the state

The Brazilian Northeast has been a constant subject for journalists of one of the world's leading media companies - The New York Times - between 1933 and 1945. This time, the US government implemented a new foreign policy for Latin America - known as the Good Neighbor Policy. It preached, various points including more respect and attention to the countries south of U.S. borders. Because of her geostrategic importance, Brazil was one of the countries that received the most attention of the bureaucracy and American press. This study investigates the multiple Northeast representations formulated in The New York Times' pages when the Americans were spotlight is on the region. It delineates similarities and differences between the NYT, the press and the governments of the United States and Brazil from the ways of conceiving this particular part of Brazil. Through the analysis of texts, photographs and maps, it is dedicated to establish connections between spaces, press and politics of the 1930s and 1940s. These decades there were relevant changes in the political landscape of both countries that permeated the news, reports and articles of NYT. Circumstances such as the 1935 armed uprisings - known as Communist Conspiracy - the installation and operation of the New State, and especially the Brazilian and US participation in World War II and the bilateral negotiations on the installation of US bases in Brazil were cardinal for the various Northeast images that circulated in the publication. The region was repeatedly subject of correspondent of the New York newspaper in Brazil, Frank M. Garcia, but also present on matters of professionals responsible for various sections: review of books, publishing, tourism, foreign affairs, etc. Along the investigated period, the visions of the region made in the articles published in the newspaper that suffered major metamorphoses. Starting with Northeast of the drought, famine and death recurrent in Brazilian literature to the most dangerous point for hemispheric defense, passing through representations of the American West lawless nineteenth century and the Latin America marked by the dominance of exotic nature and stagnation, a space to be transformed by the US technical knowledge.
