- Initial growth performance of valuable timber species in southern Brazil: Araucaria Angustifolia, Balfourodendron Riedelianum, and Parapiptadenia rígidaPublication . Topanotti, Larissa Regina; Gerber, Dionatan; Stolarski, Oiliam Carlos; Trentin, Bruna Elisa; Pertille, Carla Talita; Schorr, Luís Paulo Baldissera; Gorenstein, Maurício Romero; Nicoletti, Marcos Felipe; Bechara, Fernando CampanhãThe initial growth of three Brazilian native timber species in the city of Dois Vizinhos-PR, Brazil, was described - Araucaria angustifolia, Balfourodendron riedelianum, and Parapiptadenia rigida, using four non-linear mathematical models (Gompertz, Logistic, Logistic 4P, and Chapman-Richards). In the fi rst 4 years after planting, information about collar diameter (mm), total height (m), crown height (m), and crown diameter (m) was obtained twice a year for 12 individuals per species. Crown area (m²) and crown volume (m³) were estimated. The growth in these four variables (collar diameter, total height, crown area, and crown volume) was projected using the models, and their fi tting was assessed based on the values of the Akaike Information Criterion, the Bayesian Information Criterion, the standard error of estimate, and the coeffi cient of determination. The models generated excellent statistics for all parameters in all variables, with better statistics for collar diameter (coeffi cient of determination higher than 0.65 and standard error lower than 30%) and total height (coeffi cients of determination higher than 0.72 and standard error lower than 37%). Considering the three species, Parapiptadenia rigida
- Performance of Guazuma ulmifolia Lam. in subtropical forest restorationPublication . Gerber, Dionatan; Topanotti, Larissa Regina; Gorenstein, Maurício Romero; Vieira, Frederico Márcio Corrêa; Stolarski, Oiliam Carlos; Nicoletti, Marcos Felipe; Bechara, Fernando CampanhãWe evaluated the initial development of Guazuma ulmifolia Lam. in a reforestation experiment in the southwestern region of Parana State, Southern Brazil. In a 70 native tree species plantation (3x2 m spacing) data were collected biannually, up to 48 months, from 72 individuals of Guazuma ulmifolia. The species performance was evaluated regarding its survival (96%), root collar diameter (6.79 cm), total height (12.84 m), crown projection area (14.36 m2) and crown volume (49.86 m3). The species growth at the age of 48 months, associated to its high survival and sprouting rates, tells of excellent behavior in the region, and it could be highly recommended as a shading species for fast canopy fulfillment in forest restoration projects, especially in regions with frost occurrence.
- Vegetation and seed bank of an open-scrub bush restinga formation in the southeastern coast of BrazilPublication . Bechara, Fernando Campanhã; Salvador, Lívia Zocatelli; Ventura, Raquel Almeida; Topanotti, Larissa Regina; Gerber, Dionatan; Cruz, Izaclaudia Santana da; Simonelli, MarceloRestingas are coastal plain ecosystems located along Eastern Brazil, corresponding to about 5 000 km. The restinga vegetation is associated with the Atlantic rainforest biome and comprises four distinct main formation zones: coastal grasslands, shrublands, open-forests and marsh zones. Especially due to coastal urbanization, this is a threatened ecosystem that, through its different shrub formations, exhibits a unique mosaic as a result of the vegetation distribution in nuclei of different covering, physiognomy and floristic composition. Objective: We aimed to characterize the above and belowground composition of a conserved, non-flooded, open-scrub, nuclei (patches of bushes) formation of restinga in Linhares, ES, southeastern Brazil. Methods: The vegetation survey was conducted using the line intercept method. Diameter and height of the first six nuclei were measured in five transects separated by 50 m, totaling 30 nuclei up to 350 m away from the shore line. The phytosociology and Shannon Index of the aboveground vegetation community were calculated. In the same 30 nuclei, leaf litter and topsoil layer (15 x 15 x 10 cm) samples were collected to survey the viable seed bank, which was later placed in a greenhouse for germination and seedling identification. The Sørensen Similarity index (SSi) was used to compare the floristic composition between the leaf litter and topsoil layer seed banks. Nuclei volume and number of species were calculated as well. Results: In the aboveground vegetation, 54 plant species belonging to 32 families were identified, totaling 1 098 individuals. The nuclei showed a diversity (H’) of 3.08 nats, and an average diameter of 11.5 m (s = 9.1), area of 526.4 m2 (s = 1 081.7), and height of 2.9 m (s = 1.1). Davilla flexuosa, followed by Smilax rufescens, presented the highest IVI (Importance Value Index). A total of 1 839 seedlings from 32 species and 19 families were identified in the seed bank. Enydra sessilis (Asteraceae) had the highest seed density (544), while the family with highest species richness was Cyperaceae. A low similarity between the vegetation surveyed and the seed bank composition was found (only 5 species in common, SSi = 0.10). Conclusions: The results indicate that a post-disturbance early community, established from the seed bank, would have a substantially different species composition, but with other potential species to restore vegetation over the long-term succession.
