In this paper we describe how different ecological niche modelling techniques were successively used to generate better potential distribution models for the species and guide field work. At each step, new records were found until the species' real distribution was approximated based on a model ensemble created with five different algorithms. The estimated distribution is concentrated on a single area of 84 km 2 where the species is considered endangered.

Using a pantropical tree inventory database from closed canopy forests, consisting of 657,630 trees belonging to 11,371 species, we use a fitted value of Fisher's alpha and an approximate pantropical stem total to estimate the minimum number of tropical forest tree species to fall between ∼40,000 and ∼53,000, i.e., at the high end of previous estimates. Contrary to common assumption, the Indo-Pacific region was found to be as species-rich as the Neotropics, with both regions having a minimum of ∼19,000-25,000 tree species. Continental Africa is relatively depauperate with a minimum of ∼4,500-6,000 tree species. Very few species are shared among the African, American, and the Indo-Pacific regions. We…

Genets were monitored in 100 5 × 5 m plots and 100 2 × 2 m subplots, in a 1-ha area of swamp forest in São Paulo state, southeastern Brazil. Ramets pass through four ontogenetic stages (bifid-leafed juveniles, pinnatifid-leafed stemless immatures, stemmed nonreproductive virgins, and reproducers). Leaf size, leaf number, and leaf production rate increased during ontogeny, but diameter growth rate was higher among immatures. Stem length, number of nodes, and leaf rachis length were positively correlated across ontogenetic stages, but crown height was smaller than stem length in adult palms because of frequent leaning. Leaf number and sexual fecundity increased with ramet size, but declined in larger, senescent ramets. Clonal fecundity preceded sexual fecundity, and sexual and clonal fecundit...

Passiflora mucronata Lam. é uma das espécies nativas que integram o Banco de Germoplasma de Maracujazeiros do Instituto Agronômico (IAC), que estão sendo caracterizadas para fins ornamentais, em condições de campo, objetivando sua utilização comercial. Foram avaliados desenvolvimento vegetativo, época de florescimento, período de antese, compatibilidade, viabilidade polínica, produção de frutos, comportamento germinativo e longevidade das sementes. As flores de P. mucronata são brancas, fosforescentes e têm antese noturna, atraindo mariposas e morcegos. A viabilidade polínica permaneceu elevada (75,8%), desde a antese (18h00min h) até a manhã seguinte. A espécie mostrou-se autoincompatível. A polinização cruzada resultou em frutos ovoides, com 14,82g de peso médio, 4,59cm de diâmetro longitudinal por 2,73cm de diâmetro equatorial. A casca do fruto é delgada, amarelo-canária quando totalmente maduro. A polpa apresentou pouca suculência, sem aroma característico, mas sabor agradável. As sementes são achatadas, de coloração marrom-enegrecida, com dormência quando recém-colhidas, o que pode ser superado efetivamente com armazenamento em câmara fria e seca mais choque térmico, associados. A longevidade das sementes foi de cerca de um ano. Os acessos avaliados de P. mucronata evidenciaram se tratar de uma planta de vigor vegetativo intermediário, tolerante ao frio, com intenso florescimento, que se estende por um longo período do ano. Em função destas vantagens adicionais, pode ser utilizada como planta ornamental, uma alternativa dentro do grupo das trepadeiras indicadas para cercas vivas ou caramanchões.

A floristic and structural survey of woody vegetation was carried out in a physiognomic gradient of riparian forest of Cerrado vegetation, Campinas - SP. We sampled 25 plots, distributed along five transects, located perpendicularly to a stream. We found 971 individuals (65 standing dead trees) distributed among 35 families and 80 species. We recorded one single individual of exotic species (Citrus limon – rangpur) and a large number of individuals of endangered species (Luetzelburgia guaissara, Myroxylon peruiferum and Trichilia hirta) indicating that the Santa Elisa study area retains much of the original characteristics of its native vegetation. The small number of exclusive Cerrado species in the study area indicates that riverine environments represent a very different condition in relation to that of the Cerrado. Except for swampy areas, which are more homogeneous and floristically similar to each other due to adaptations to greater environmental constraints, the riverine forest physiognomies showed greater internal floristic heterogeneity, even considering only those located in Cerrado areas. This emphasizes the importance of studying riverine forests flora for each particular region, especially when restoration or management actions are needed. At the Santa Elisa riverine-cerrado transition fragment, riparian species were found throughout gradient up to the limit of the study area showing that a distance of at least 50 m far from the stream should be preserved in order to keep the riparian environment.

However, in 1932, Otto Degener suggested that the yellow passion fruit had its origin in Australia through breeding, calling it P. edulis forma flavicarpa, and that it could be distinguished by the color of the fruit, the deeper shade of purple of the corona, and the presence of glands on the sepals. These distinctions do not support themselves, for the glands are common to the species (although they may be absent), and the corona has a wide range of colors, regardless of the color of the fruit. A more critical ingredient is the fact that the external coloration of the fruit is a character of complex inheritance and is not dominant, thus displaying a number of intermediate colors, making it difficult to identify the extreme colors. For the correct scientific naming of agricultural plants, the International Code of Botanical Nomenclature must be used in conjunction with the International Code of Nomenclature for Cultivated Plants, with the selections with significant agronomic characteristics recognized and named cultivars. In accordance with the international convention promoted by the UPOV, of which Brazil is a signatory, several colors (light yellow, yellow, orange yellow, pink red, red, red purple, green purple, purple, and dark purple) can be recognized in order to adequately characterize passion fruit cultivars within the species P. edulis. At taxonomic level, Passiflora edulis Sims must be used for any plant and color of sour passion fruits, in combination with a cultivar name for the selected materials.

Vinte e sete fragmentos de vegetação nativa foram estudados. Foi realizada a caracterização morfológica, classificação e coleta do solo para análises, bem como o levantamento florístico-fitossociológico do estrato arbóreo. A análise de correspondência canônica identificou as variáveis mais bem correlacionadas com a distribuição das espécies e identificou 15 variáveis que explicaram 31% da variância nos dois primeiros eixos. A classificação dos solos discriminou as fitofisionomias estudadas, Argissolos associados às matas e Latossolos aos cerrados, indício de que baixa fertilidade, baixa retenção de água e drenagem acentuada do solo favorecem o estabelecimento de cerrado. Parâmetro "n" da curva de retenção de água, densidade, H+Al, Ca, Al, K e Mg trocáveis, macroporos e matéria orgânica do solo foram os atributos dos solos mais efetivos nessa diferenciação fitofisionômica. A barreira química imposta pelo excesso de Al e deficiência de Ca no horizonte B e a baixa retenção de água nos solos sob cerrado favorecem as espécies Luehea grandiflora, Persea willdenovii, Xylopia aromatica e Erythroxylum daphnites, abundantes e exclusivamente encontradas nos fragmentos de cerrado.

A series of mistakes occurred in relation to the correct citation of the species. The aim of the present paper was to evaluate the problems and identify the scientific correct form of Passiflora alata nomenclature. The species must be cited as Passiflora alata Curtis and was published originally in 1788, in the Botanical Magazine.

The situation is not different for Brazilian herbaria, currently sharing more than two million easily accessible records on the Web. Properly dealing with this reality is a crucial task when using this kind of data for ecological niche modelling (ENM), so that errors and uncertainties do not generate misleading results in conservation. Here we investigate some of the issues that can be found in herbarium specimen data, describing a set of automatic procedures that can be used for a prior selection of records for ENM. In total, 11531 records for 135 species of Passifloraceae that natively occur in Brazil were analyzed considering different spatial resolutions, ranging from 30 arc-seconds to 10 arc-minutes. After applying the procedures, the proportion of spatially unique records was 9.3% for the highest resolution considering all species, with an average number of 8 records selected per species. These numbers increased to 17% and 16, respectively, for all other resolutions. This scenario highlights the importance of using data quality filters and further developing ENM presence-only methods that can work with a low number of records per species. Automatic procedures still cannot discard expert review, but they can greatly facilitate it by drawing attention to a much smaller number of records potentially useful for ENM. Most of the data quality procedures described here can also be applied to other taxonomic groups, regions and specimen data sources.
