Este trabalho trata do levantamento florístico-taxonômico da família Boraginaceae em um trecho de Caatinga da Estação Ecológica Raso da Catarina, Bahia, Brasil. Foram encontrados sete espécies e três gêneros de Boraginaceae: Cordia (C. globosa (Jacq.) Kunth, C. leucocephala Moric. e C. rufescens A.DC.), Heliotropium (H. angiospermum Murray e Heliotropium elongatum (Lehm.) I.M. Johnst.) e Tournefortia (T. rubicunda Salzm. ex A.DC. e T. salzmannii DC.). São apresentadas chaves para identificação de gêneros e espécies, além de descrições, ilustrações, comentários, dados de distribuição e hábitat.

This research assessed the relationship between students' perceptions and socioeconomic factors in urban and rural communities surrounding Atlantic rainforest protection areas in Pernambuco, Brazil. We tested whether the utilitarian concept of forests has a determining role in the student community's perception of protected areas. The study was conducted in eight schools in communities surrounding three protected areas, through questionnaires for 410 middle and High school students. The majority of students highlighted the utilitarian importance of forests, but approximately 60% of students did not answer the question regarding the importance of protected areas, displaying a disconnection between perceptions of forests and of protected areas. The students' environmental perception index was significantly different between rural and urban zones, but in both zones, on average, protected areas had a positive utilitarian importance, exclusively related to the protection of nature. Negative aspects of the students' perceptions of protected areas were related to social problems such as lack of law enforcement and land expropriation. Schooling and residence setting had a small (6.7%) but significant influence on student perception. Our results indicate that environmental managers in protected areas need to promote meaningful interaction with student communities from rural and urban settings, to increase the efficiency of these areas and to conserve biological diversity.

The use of agricultural pesticides is increasingly associated with public health problems and negative impacts on the environment, in addition to the lack of protective actions developed by Brazilian environmental agencies. Our objective in this study was to analyze the relationships in the process that lead to the perception of risk of damage to human health by the use of pesticides in the riverine farming communities of the São Francisco Valley, in Brazilian northeast. We carried out a qualitative literature review, using the Constructivist Grounded Theory applied to the review of published scienti c articles. The elements in the perceptive process found were: 1) the environment; 2) conditioning factors; 3) the perception of the human body; 4) the memory; 5) socio-cognitive processing; 6) automatic response; 7) the decision process and 8) the behavior. Each of those elements and its relationships guide where the causes of an inadequate perception to resolve them.

Indigenous people have an intrinsic relationship with the flora used in healing systems. However, data about plants used to treat intestinal parasitosis, which are one of the main morbidity and mortality causes among indigenous peoples, remain scarce. Thus, the aim of the current study is to survey antiparasitic plants used by the Kantaruré-Batida community and to investigate whether their ethno-medico-botanical knowledge is spread. Therefore, it adopted interviews and free lists. Thirty-one (31) indigenous individuals were interviewed and they mentioned 21 plant species. Most respondents (91%) acquired the traditional knowledge through hereditary transmission and spread it (77%) in the same way. Only 35% of the respondents adopt medicinal plants as the first cure resource, besides associating the decrease of such use to their proximity to health care services. Thus, it is worth taking actions to help preserving the local knowledge and biodiversity in order to avoid the loss of indigenous therapeutic treatments.
