Abstract DNA barcoding helps to identify species, especially when identification is based on parts of organisms or life stages such as seeds, pollen, wood, roots or juveniles. However, the implementation of this approach strongly depends on the existence of complete reference libraries of DNA sequences. If such a library is incomplete, DNA-based identification will be inefficient. Here, we assess if DNA barcoding can already be implemented in species-rich tropical regions. We focus on the tree flora of São Paulo state, Brazil, which contains more than 2000 tree species. Using new DNA sequence data and carefully assembled GenBank accessions, we assembled 12,113 sequences from ten different regions. The ITS, rbcL, psbA-trnH, matK and trnL regions were better...

O número de variedades de tangerinas utilizadas economicamente é muito restrito, apesar da importância comercial deste grupo de citros. O Banco Ativo de Germoplasma de Citros do Centro de Citricultura Sylvio Moreira/IAC possui em torno de 383 acessos de tangerineiras e híbridos, os quais têm sido estudados sob o ponto de vista botânico, genético e agronômico. Este trabalho visa descrever por meio de 38 caracteres morfológicos, os frutos das tangerineiras Satsuma Unshiu Wase, Clementina, Mel, Portuguesa, Natsu Mikan, Dancy, Cascalho, Campeona, Mexerica-do-Pará e Mexerica-do-Rio. Foram coletados 30 frutos maduros de cada acesso, sendo 10 frutos por planta, num total de 3 plantas por acesso. As tangerineiras, enxertadas sobre tangerineira Cleópatra e...

Structure, diversity, and spatial patterns in a permanent plot of a high Restinga forest in Southeastern Brazil
Provedor de dados: 39
Autores: Lima,Renato Augusto Ferreira de; Oliveira,Alexandre Adalardo de; Martini,Adriana Maria Zanforlin; Sampaio,Daniela; Souza,Vinícius Castro; Rodrigues,Ricardo Ribeiro.
We assessed the structure, diversity and distribution of tree species in a 10.24-ha permanent plot of high Restinga forest (HRF) in southeastern Brazil. We sampled 15,040 individuals belonging to 45 families, 87 genera and 116 species (density= 1,468 trees ha-1, and basal area= 28.0 m² ha-1). Mean richness was lower than other types of tropical forests and other HRFs that have been less intensively sampled, which is probably due to the younger age and hydromorphy of the soils in the study site. Tree density, basal area, species composition, and diversity all varied considerably depending on the size class considered. The studied plot had a density similar to other tropical forests but with a smaller basal area (fewer individuals &gt; 60 cm in diameter),...

Ethnobotany of rural people from the boundaries of Carlos Botelho State Park, São Paulo State, Brazil
Provedor de dados: 39
Autores: Hanazaki,Natalia; Souza,Vinícius Castro; Rodrigues,Ricardo Ribeiro.
In this article we describe and analyze the use of plant resources in a region nearby a conservation area. Data were collected through semi-structured interviews, in which we asked the interviewees to free list the plants known. Species cited were identified through collection of botanical samples, and field observations. Fifty-eight inhabitants were interviewed; banana farming, cattle ranching, and extracting palm hearts are their main economic activities. A total of 248 ethnospecies were mentioned, including over 200 botanical species. Plants were grouped into four habitats (A = well-preserved forest; B = disturbed forest in old successional stages; C = recently disturbed environments; D = cultivated areas and home gardens). Highest diversity is known...

Considerações sobre a delimitação de Mecardonia procumbens (Mill.) Small. (Scrophulariaceae)
Provedor de dados: 39
Autores: Souza,Vinícius Castro.
No presente trabalho foram reconhecidas cinco variedades para Mecardonia procumbens (Mill.) Small (Scrophulariaceae), sendo que novas combinações são propostas. Além disso, três espécies anteriormente referidas para o Brasil foram incluídas na sinonímia destas variedades, o que faz com que no Brasil passe a ser considerada a existência de apenas quatro espécies de Mecardonia: M. pubescens Rossow, M. serpylloides (Cham. &amp;amp; Schltdl.) Pennell, M. grandiflora (Benth.) Pennell e M. procumbens (Mill.) Small. Neste trabalho são fornecidas chave de identificação para as variedades e lista com as sinonímias das mesmas.

Ecologic salience and agreement on the identification of tree species from Brazilian Atlantic Forest
Provedor de dados: 49
Autores: Hanazaki,Natalia; Mazzeo,Rogério; Duarte,Alexandre Romariz; Souza,Vinícius Castro; Rodrigues,Ricardo Ribeiro.
This study aims to investigate the consensus among informants in the naming of tree species from a high diversity environment, the Brazilian Atlantic Forest (Sete Barras, SP), through a methodological procedure based on standardized stimuli. Seven selected local experts on tree species used for timber and handicrafts were asked to walk individually across the same area of 1.72 ha and identify and name all the known trees of more than 4 cm DBH (diameter at breast height) using common names. All trees were botanically identified, and their DBH and height were measured. The ecologic salience of tree species, expressed in terms of abundance, average height and DBH, was tested in relation to the informants' knowledge and species naming. The guided walks...
