“…The vertical distribution of the tree stratum presented five height class centers varying from 2.0 to 20 m, with a mean of 8.29 m in height. The high number of individuals in the second lowest height class center ( Figure 4A) is an important indicator of the forest renewal capacity due to the establishment of these individuals in smaller classes (Pinheiro & Monteiro, 2009).…”

The objective of this work was to evaluate the arboreal component of a Dense Ombrophilous Lowland Forest fragment through evaluations of richness, structure and diversity. For the sampling of this component, we implanted 40 sample units of 10 × 25 m. We measured all arboreal individuals who presented circumference at breast height ≥ 15 cm, 1.30 m from the ground level. The tree stratum presented 1324 individuals, 100 species, 64 genera and 38 families. The Fabaceae family had the highest wealth and Anacardiaceae was the most abundant. The Shannon index and Pielou equability were 3.60 nats.ind.-1 and 0.78, respectively, suggesting the existence of relevant ecological dominance in the community. The results of this work emphasize the ecological importance of this remnant for maintaining the local flora and fauna, also emphasizing the importance of preserving Atlantic Ombrophilous Forests, particularly in the Zona da Mata of Pernambuco.

“…The climax species category was not included in successional classes because many typical understory plants occur in both stages, more mature and other succession phases, according to Gandolfi et al (1995). The inclusion of species in ecological groups followed descriptions of Batalha and Mantovani (2001), Paula et al (2004), Pinheiro and Monteiro (2009) and field observations. Scientific nomenclature and family classification follow the Reflora (2014).…”

We investigated the efficiency of different kinds of perches in attracting seed disperser-birds and increasing the seed rain in a degraded area located in the northeast region of São Paulo State. We installed seed traps under natural perches (NPs, living trees); simple artificial perches (SAPs) of 3m tall and a crossbar; elaborate artificial perches (EAPs) of 7m tall and three crossbars, and in a control area. Results showed the number of bird-dispersed seeds deposited was proportional to the number of structures for perching. The NPs also have provided other resources for birds such as food and shelter. Comparing visitation between artificial perches, there was greater use of EAPs also for having more perching structures and for being taller, providing better airspace visibility for predatory birds and tyrant-flycatchers, important seed dispersers. Thus, natural and artificial perches with similar characteristics to the EAPs are the most recommended as a base or complementary method for the restoration of degraded areas near to propagules source, also contributing to the maintenance of local fauna.Keywords: birds, seed dispersal, frugivory, perches, forest restoration.Uso de poleiros e dispersão de sementes por aves em um pasto abandonado no Parque Estadual de Porto Ferreira, sudeste do Brasil ResumoInvestigamos a eficiência de diferentes modelos de poleiros na atração de aves dispersoras e no incremento da chuva de sementes em uma área degradada localizada na região nordeste do Estado de São Paulo. Instalamos coletores de sementes sob poleiros naturais (PNs, árvores vivas); poleiros artificiais simples (PASs), com 3m de altura e um ponto de pouso; poleiros artificiais elaborados (PAEs), com 7m de altura e três pontos de pouso e coletores em área aberta (testemunha). Verificamos que o número de sementes ornitocóricas depositadas nos coletores aumentou proporcionalmente à quantidade de estruturas de pouso dos poleiros. Os PNs também disponibilizaram outros recursos para a avifauna, como alimento e abrigo. Comparando-se a visitação entre os poleiros artificiais, houve maior utilização dos PAEs que, além de apresentarem mais pontos de pouso, são mais altos, fornecendo melhor visibilidade do espaço aéreo para aves predadoras e que apanham insetos em vôo, como os tiranídeos, importantes dispersores de sementes. Neste sentido, poleiros naturais e artificiais com características similares aos PAEs são os mais recomendados como método base ou complementar na restauração de áreas degradadas próximas a fontes de propágulos, contribuindo também para a manutenção da fauna local.Palavras-chave: aves, dispersão de sementes, frugivoria, poleiros, restauração florestal.

“…The vegetation of Bauru Botanic Garden (322 ha) comprised 'cerradão' and cerrado sensu stricto, which are forestand savanna-type physiognomies, respectively, typical of Cerrado areas; semideciduous and gallery forests are also part of the landscape (Pinheiro and Monteiro 2009). The garden is at 630 m of altitude, and the soil is a red latossol, under the influence of a seasonal climate with a dry winter (May-September) and wet summer (October-April).…”

Non-destructive model to estimate the leaf area of multiple Vochysiaceae species

et al. 2015

View full text Add to dashboard Cite

Leaf area (LA) is commonly used to evaluate plant traits such as leaf development and plant growth, which depend on sunlight interception. However, methods for obtaining LA are destructive and require many leaf samples that might not be available. The use of linear equations to estimate LA without destructive procedures has been successfully used in crops and weeds studied in the field and in potted-plant experiments. In the Brazilian savanna (Cerrado), many studies still depend on destructive leaf sampling because equations would be specific for each species. We developed a non-destructive model to estimate LA of five Vochysiaceae species from the cerrado, as this family exclusively comprised Al-accumulating species. In this study, LA versus leaf length (L) and leaf width (W) was regressed, and the best-fitted model (LA = -2.133 ? 0.719 LW, R 2 = 0.99) was validated to estimate LA in Qualea cordata Spreng., Qualea grandiflora Mart., Salvertia convallariodora A. St.-Hil., Vochysia cinnamomea Pohl., and Vochysia tucanorum Mart. with precise accuracy. This model may help scientists with distinct interests in plants from this family.
