Benth. ex Walp. The study was developed in the Laboratory of Analysis of Forest Seeds and in the Forest Nursery of the Forest Science Department of the Federal Rural University of Pernambuco. For the biometry 100 seeds were used. The length, width and thickness were measured using a pachymeter, where the measurements were expressed in millimeters. The development of seedlings and seedlings was observed daily, describing all the characteristics of external morphology, such as radicle, hypocotyl, cotyledons, epicotyl, germination type, among other important information. The seeds of Parkia pendula had an average length of 10.15 mm; width and average thickness of 5.45 and 3.20 mm, respectively; the germination is of the epidermal type fanerocotiledonar. Morphological characters proved to be reliable for the recognition of seeds and seedlings in their natural habitat.

The area is located in Engenho e Destilaria Dourado in Moreno, Pernambuco, Brazil. Fifteen plots of 10 x 25 m for the adult component (CBH ≥ 15 cm) and 15subplots of 1 x 25 m for the regeneration (CBH 1 m) were located. The sampled individuals were classified into family, genus and specie, and the species classified for the succecional group (pioneers, early secondary and late secondary) and the dispersion syndrome (anemocorous, autochorous and zoochorous). Four hundred and forty-four adult individuals and 407 regenerants, belonging to 31 families, 47 genera and76 species, were sampled. The families with the highest species richness were Melastomataceae and Myrtaceae. This fragment is in early succession, since 82% of the species are pioneers or early secondary. The dispersion predominant was the zoochorous. The knowledge of the species presents in these areas, as well as the succession stage and the dispersion syndrome, is of utmost importance in the development of conservation and restoration intervention of these areas in the Atlantic Forest.

Consequently, many ecosystems were destroyed, including riparian forests. The number of studies of riparian restoration has increased but comparative studies on the belowground effects of common reforestation strategies are rare. Here, we compared soil microbial properties among four different land use types: native rainforest, sugar cane plantation, single species reforestation, and mixed species reforestation, each replicated at two spatially independent sites. Soil samples were taken in 2013 and 2014, that is 2 and 3 years after reforestation, respectively. In both years, land use types had a significant effect on basal respiration, microbial biomass, and specific respiration (whereas specific respiration was marginally affected in 2014). In 2013, basal respiration in sugar cane plantations was significantly lower (−65%) when compared to native forests. In 2014, basal respiration (+60%) and soil microbial biomass (+90%) were significantly higher in mixed species reforestation compared to sugar cane, whereas single species reforestation had comparable values as in sugar cane plantations. Our results indicate that soil microbial biomass and activity respond rapidly to land use change when mixed species reforestation is used. Thus, using mixed species reforestation may enhance the provisioning of ecosystem services already in the short term.

O presente trabalho teve como objetivo avaliar a chuva de sementes e o estabelecimento de plântulas de espécies arbóreas em Floresta Atlântica, localizada na região Nordeste do Brasil. Para amostragem da chuva de sementes foram alocados 60 coletores (área de 0,196 m²), ficando equidistantes, aproximadamente, de 50 m. As coletas foram realizadas com intervalo de 30 dias por um período de 12 meses. Para avaliar o estabelecimento de plântulas foram alocadas subparcelas ao lado dos coletores, totalizando 60 subparcelas de 0,25 m² cada. Os indivíduos arbóreos identificados pelos diásporos coletados na chuva de sementes e pelas plântulas estabelecidas no fragmento foram contados e classificados quanto à síndrome de dispersão e grupo sucessional. A chuva de sementes foi representada por 60 morfoespécies e 20 famílias botânicas. O grupo ecológico e a síndrome de dispersão predominante foram de espécies secundárias iniciais e zoocórica, respectivamente. Em relação às plântulas estabelecidas foram contadas 122 plântulas, sendo Tapirira guianensis L. com maior número de plântulas. A chuva de sementes apresenta potencial para manutenção da dinâmica florestal por apresentar alta riqueza de espécies que compõe a atual vegetação, sendo composta, predominantemente, por espécies que produzem frutos abundantes com dispersão zoocórica que servem de alimento para fauna. Enquanto poucas sementes germinam para formar o banco de plântulas, a maioria está contribuindo para formação do banco de sementes. Palavras-chave: dispersão; mecanismo de regeneração; conservação.

The fruits were collected from the matrices trees in the Jardim Botânico do Recife (JBR), Pernambuco. From 10 pathogen-free A. heterophyllus matrices, 50 fruits (multiple fruits, which in the research were considered as single fruit) and 500 seeds were collected, being measured length, width and thickness, using a tape measure (for fruits) and digital caliper (precision 0.001 mm) for the seeds, as well as weighing on a precision scale. The seeds were classified by size: Small (≤ 2.5 cm), medium (2.6 to 3 cm) and large (≥ 3.1 cm). The germination test was conducted in a greenhouse of the JBR, with a 50% shading screen. The Original Research Article container used was a 50 x 25 x 5 cm polypropylene tray with holes at the bottom to provide drainage. The obtained results allow inferring that the seed size did not influence the vigor on heterophyllus germination in a greenhouse. The variation found in fruit size and number of seeds per fruit, as well as field observations regarding fruit and seed morphology, pulp flavor and consistency, allows us to infer that there is a possibility of several vari in the studied site.

DC. sob diferentes níveis de sombreamento. Este trabalho teve como objetivo avaliar o desenvolvimento de mudas de Aspidosperma discolor A. DC., de duas procedências, submetidas a pleno sol e diferentes níveis de sombreamento, em um viveiro florestal, além de identificar seu grupo ecológico efetivo. Folículos amarelo-esverdeados fechados e pré-maduros foram coletados de dez matrizes selecionadas aleatoriamente em duas populações naturais de fragmentos de Floresta Ombrófila Densa de várzea, ambas em Pernambuco, Brasil. As mudas dessas sementes foram desenvolvidas em diferentes níveis de sombreamento. Após o desenvolvimento das mudas, foram avaliadas as seguintes variáveis: número de folhas, área foliar e biomassa seca. A espécie apresentou plasticidade fenotípica favorável à sua aclimatação em ambientes com condições de sombreamento moderado a intermediário, característica evidenciada em pequenas clareiras; à densa, típica de vegetação com dossel fechado. Para a produção de mudas da espécie em viveiro florestal, destaca-se um nível de sombreamento de 50%, pois favorece maior crescimento e biomassa das partes aérea e radicular. Além disso, apresenta um comportamento ecológico peculiar de táxons ciófilos facultativos ou de estágios intermediários de sucessão. Palavras-chave: mudas florestais; ecologia florestal; biomassa vegetal; fisiologia vegetal; Floresta Ombrófila Densa Abstract This study aimed to evaluate the development of Aspidosperma discolor A. DC. seedlings two different origins subjected to full sunlight or different shading levels in a forest nursery, in addition to identifying its effective ecological group. Closed and premature greenish-yellow colored follicles were collected from 10 randomly selected mother trees in two natural populations of lowland Dense Ombrophilous Forest fragments, both in Pernambuco, Brazil. The seedlings of these seeds were developed under different shading levels. After the seedlings were developed, the following variables were evaluated: number of leaves, leaf area and dry biomass. The species showed favorable phenotypic plasticity for its acclimatization in environments with moderate to intermediate shading conditions, a characteristic evidenced in small gaps; as well as for dense conditions, typical of vegetation with a closed canopy. A shading level of 50% stood out to produce A. discolor seedlings in a forest nursery, as it favors greater growth and biomass of the shoot and root parts. In addition, it presents peculiar ecological behavior of facultative sciophilous taxa or intermediate succession stages.

DC, species of Apocynaceae family, occurring in lowland Atlantic Forest in the State of Pernambuco. To perform the analysis, reproductive units were collected in two fragments of Atlantic Forest in the cities of Recife and Camaragibe respectively. In the evaluation it was determined length, width, thickness, weight, fresh weight and number of seeds and fruits per kilogram; while the seed diameter, thickness, weight of fresh mass and percentage predation by insects were obtained. It was found that the average length and thickness of fruits and diameter of seeds coming Camaragibe were significantly higher, by Mann-Whitney test at 5% probability. The averages of the widths of the fruits, the seeds of thicknesses, the weights of fresh weight of the fruits and seeds and number of seeds per fruit and per kilogram showed no statistical differences between t...

The leaves of three trees of each species were sampled and the concentration of micronutrients was determined, estimating their content and efficiency of biological utilization. The efficiency of biological utilization followed the decreasing order: Mn > Cu > Zn > Fe. Jatropha mollissima and Spondias tuberosa were less efficient in the use of Fe and Senegalia paniculata and Croton blanchetianus, in the use of Zn. However, Piptadenia stipulacea and Mimosa ophthalmocentra were very efficient in using Fe and Mn. The nutritional efficiency of the species can serve as a criterion for choice of species in forest restoration programs.

This research aimed to identify the current situation, in terms of species composition and diversity, of two riparian forests under restoration based on a reference ecosystem, the Brazilian Atlantic Forest. Twenty permanent plots (250 m²) were located in areas under restoration process (AR1 and AR2) and in a forest fragment of the region which served as a reference ecosystem (ER). We sampled, identified and classified all tree individuals with CBH ≥ 15.0 cm in each plot. Aiming to understand species richness and diversity, besides the traditional indexes (Shannon and Simpson), we also estimated the effective numbers of Hill’s diversity (qD = 0, 1 and 2) considering rarefaction (P ≤ 0.05); and to detect floristic similarities among the study areas we performed a Principal Coordinate Analysis (PCoA). We found d...

Foram instaladas 15 parcelas de 10 x 25 m, totalizando uma área amostral de 3.750 m 2. As parcelas foram distribuídas na área de forma sistemática, em linhas paralelas à borda sul do fragmento. A primeira linha foi instalada a 10 m da borda, as demais distando 50 m entre linhas, e em todas as linhas as parcelas foram alocadas a cada 25 m uma da outra. Encontraram-se 401 indivíduos pertencentes a 53 espécies botânicas, o que representa uma densidade estimada de 1.069 ind. ha-1. O índice de diversidade de Shannon-Wiener foi de 3,2 nats ind-1. O padrão de distribuição espacial das espécies nas 15 parcelas apresentou 6 espécies com padrão agregado, 15 espécies com tendência ao agrupamento e 32 apresentaram distribuição uniforme na área. A área de borda apresentou maior densidade e diversidade de espécies arbóreas que o interior do fragmento, porém a maior porcentagem do Valor de Importância (VI) foi representada por poucas espécies. Após 100 m para o interior do fragmento, o efeito de borda tende a minimizar seus impactos na estrutura da vegetação arbórea.
