“…Devido a sua diversidade climática , edáfi ca e geomorfológica (AB 'SABER, 1995), a Caatinga é composta por um mosaico de formações savânicas, além de fl orestas deciduais e úmidas (QUEIROZ, 2006;RODAL, 2008). Apesar de sua boa representatividade entre os biomas brasileiros, pouco se conhece sobre a sua fl ora, além disso, muitos trabalhos que visam ao levantamento de espécies na Caatinga encontram-se concentrados em determinadas regiões, principalmente ao norte do bioma (QUEIROZ, 2006;.…”

RESUMO:Devido à heterogeneidade fi tofi sionômica da vegetação na região Norte Mineira, a estrutura e riqueza de seus remanescentes são consideravelmente variáveis, e, embora pouco conhecida, trata-se de uma região amplamente explorada economicamente. Objetivou-se, com este estudo, caracterizar a estrutura e fl orística de uma área de caatinga arbórea, localizada em Juvenília, Minas Gerais. Foram alocadas 20 parcelas de 20 × 20 m (400 m 2 ) totalizando 0,8 há. Nelas foram mensurados todos os indivíduos com CAP (circunferência à altura do peito) ≥ 10 cm. Para complementar a listagem fl orística do componente arbustivoarbóreo, foram realizadas quatro visitas para coleta de material botânico entre janeiro e dezembro de 2003. A composição fl orística foi representada por 64 espécies arbóreas, destas, 47 foram amostradas no levantamento fi tossociológico. A diversidade da área foi de H' = 2,90 e J' = 0,76, com dominância das espécies Anadenanthera colubrina, Poincianella pluviosa e Myracrodruon urundeuva que apresentaram os maiores valores de Dominância: 26,3, 13,1 e 20,3%; Densidade: 11,2, 16,6 e 10,1%; Frequência: 6,2, 6,5 e 5,5% e Valor de Importância: 14,6, 12,1 e 12,0%, respectivamente. A distribuição diamétrica da comunidade tendeu à normalidade, com menor quantidade de indivíduos nas classes diamétricas menores e maiores. A comunidade estudada mostra padrões estruturais e fl orísticos semelhantes a outros remanescentes de fl orestas deciduais em bom estado de conservação, dentro e fora do bioma Caatinga, embora tenha sido evidenciada a presença de interferências antrópicas na área.Palavras-chave: Distribuição diamétrica, diversidade, dominância ecológica. STRUCTURE AND FLORISTICS OF A REMNANT OF ARBOREOUS CAATINGA IN JUVENÍLIA, NORTHERN MINAS GERAIS, BRAZIL ABSTRACT: Due to the phytophysiognomic heterogeneity of the northern Minas Gerais region, the structure and richness of local vegetation remnants vary considerably, and regardless of the fact that the region is yet little known, it has been widely explored economically. The objective of this study is to characterize the structure and fl oristics of a fragment of Arboreous

“…Within its natural range (NE, SE and W Brazil, N Argentina, Paraguay, Bolivia and C-S Peru), Ceiba speciosa is a very common tree typical of mature (but not final) dynamic stages of drought-tolerant semi-deciduous forest (Kennard, 2002;Oliveira-Filho & al., 2006) and the socalled cerrado, a tree savanna-like community (Ruggiero & al., 2002;Rodal & al., 2008), but it can thrive also along wet river valleys (Bianchini & al., 2000;Gibbs & Semir, 2003). This subtropical tree is perfectly adapted to stand a relatively dry season, which lasts from May to August.…”

The abiotic and biotic characteristics of the first sites where floss silk tree behaves as a casual alien plant in the Mediterranean Europe are described. The species was probably first planted in botanical gardens of southern France few decades before mid XIX century. It was introduced in Palermo in 1896, a city which appears to match very well its climatic requirements. According to the available information on its biology and ecology in both its original and secondary range, the floss silk tree should not become an invasive alien plant in the Mediterranean. Nevertheless, several gaps need to be filled in order to increase our understanding of future trends of Ceiba speciosa in southern Europe, in particular, the eventual role of pollinators and seed dispersers outside the species' natural range.

“…Brazil is a continental country with six different biomes, Amazon, Atlantic Forest, Cerrado, Caatinga, Pantanal and Pampa [1], of which 3 are represented in the State of Bahia (Atlantic Forest, Caatinga, Cerrado) [2,3]. Traditional knowledge of medicinal plants used by indigenous populations of rural areas of Bahia has not received enough attention so far, although in northeastern Brazil there are ethnobotanical studies recently published [4][5][6][7][8].…”

The present study evaluated ethno medicinal knowledge of people in the rural community of São Sebastião, Vitória da Conquista, Bahia, Brazil. Using semi-structured interviews, 84 randomly chosen individuals informed about the use of traditional medicinal plants in their community, thereby identifying their therapeutic potential, which were categorized according to the ICD-10 (International Statistical Classification of Diseases and Related Health Problems). The collected data were analyzed with using the Informant consensus factor (ICF), the Relative importance (RI) and the scores were calculated by using Fidelity level (FL). Forty-six species traditionally used in treatment of ailments were categorized as diseases: digestive system, respiratory problems, general symptoms/signs, nervous system and circulatory system. Lippia alba, Cymbopogon citratus and Foeniculum vulgare had a RI >1, indicating important value to the community. Highest values of FL were: Spondias purpurea, Bauhinia forficata, Punica granatum, Matricaria chamomilla, Stryphnodendron adstringens, Foeniculum vulgare, Mentha piperita, Amburana cearensis and Dysphania ambrosioides. S. purpurea, to treat hypertension, and Amburana cearensis (indigestion) deserve in depth pharmacological and toxicological studies so that they might be included in the National Program of Medicinal Plants and Phytotherapics of the Brazilian Sistema Único de Saúde and safely prescribed by regional health teams, lowering costs for local health system.
