A thermal analysis has been applied to characterization of food and food products. Taking into account the problems of desertification and agricultural practices able to provide income to the population at the semi-arid region of Northeastern Brazil, this work presents the results of the chemical, thermal and kinetic characterization by thermogravimetry and differential scanning calorimetry of the seed derivatives of favelone (cnidoscolus quercifolius), aiming at the application of these materials as an alternative of food source for animals and for the human population at this brazilian region.

The Caatinga biome is located in the semi-arid region of northeastern Brazil and covers about 37 % of Piauí state. The main objective of the present study was a characterization of the Caatinga flora of the farm of Morro do Baixio, in state of Piauí, Brazil (06°51’13” S; 41°28’15” W, at 400 to 540 m above sea level) in view of the fact that very few such surveys were conducted in the state. The flora of the farm was surveyed monthly, during a year, to gather herbs, epiphytes, parasites, sub shrubs, shrubs and trees. We encountered 136 species belonging to 46 families, including a new species of Bauhinia. The richest families were Caesalpiniaceae (15 spp.), Fabaceae (11 spp.), Bignoniaceae and Mimosaceae (both with nine spp.). We observed a higher frequency of typical species from sedimentary Caatinga. However, local conditions favor the appearance of species that occur in Carrasco and Cerrado.

This study aimed to evaluate the infection rates of snakes by pentastomids in the semi-arid region of Brazil. Fifteen snakes (four Micrurus ibiboboca (Merrem, 1820) and eleven Philodryas nattereri Steindachner, 1870) were collected between January and April of 2005, in the municipality of Crato (07° 14' S and 39° 24' W), State of Ceará, Brazil. Laboratorial analysis of the respiratory tracts of the sampled snakes indicated differences in host infection rates: four individuals of P. nattereri (36.4%) were infected by Cephalobaena tetrapoda Heymons, 1922 (mean infection intensity 1.5 ± 0.28, 1-2) and three specimens (27.3%) by Raillietiella furcocerca (Diesing, 1863) (2.3 ± 1.32, 1-5). Only one individual of M. ibiboboca (25%) was infected by a non-identified species of Raillietiella sp. These are the first data on pentastomid infection in snakes in Northeastern Brazil and both snake species comprise new host records for the pentastomids. The results also indicate that the generalist parasites C. tetrapoda and R. furcocerca share their definitive hosts.

The development of the mangrove in Ceará state, northeastern Brazil, is limited by local environmental and climatic factors, associated with the variables that determine the region’s semi-arid climatic conditions. The same conditions also contribute to the installation of artisanal saltworks in estuarine environments. The artisanal production of salt peaked in the 20th century, but with the decline of this activity, the salt evaporation ponds were abandoned, and have been incorporated back into the natural marine-estuarine environment and colonized by mangrove forests. In the early 2000s, however, the expansion of shrimp farming operations impacted this same environment. The present study was based on a spatiotemporal analysis of the natural regeneration of the mangrove vegetation in abandoned salt pond areas in the Brazilian semi-arid region between 1968 and 2009. The integrated analysis of mangrove ecosystem dynamics and the legislation that regulates the licensing of these economic activities identified a number of technical problems in the formulation and execution of the COEMA resolution 02/2002, which permits the installation of shrimp farms in areas dominated by the mangrove. The findings of the present study reinforce the need for a careful reformulation of the Ceará state environmental legislation, in order to guarantee the maximum possible conservation of the coastal zone.
