Natural regeneration under reforestation of Araucaria angustifolia and Pinus sp...
Carvalho, Joema; Velazco, Santiago José Elías; Pereira, Tiaro Katu; Galvão, FranklinThis study aimed to assess the natural regeneration in stands of Araucaria angustifolia (PA) and Pinus sp. (PP) without management in Campinhos State Park, in the Municipality of Tunas do Paraná, Parana State, Brazil. Eighteen plots of 10 m2 were installed, 7 plots for PA and 11 for PP. All trees higher than 1.5 m were sampled and their circumference were measured at 1.30 m above ground level. In PA stand there...
Climate seasonality limits leaf carbon assimilation and wood productivity in tr...
Wagner, Fabien H.; Hérault, Bruno; Bonal, Damien; Stahl, Clment; Anderson, Liana O.; Baker, Timothy R.; Sebastian Becker, Gabriel; Beeckman, HansMade available in DSpace on 2018-12-11T17:02:44Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-04-28; The seasonal climate drivers of the carbon cycle in tropical forests remain poorly known, although these forests account for more carbon assimilation and storage than any other terrestrial ecosystem. Based on a unique combination of seasonal pan-tropical data sets from 89 experimental sites (68 include ...
Grupos florísticos e espécies discriminantes em povoamento de Araucaria angusti...
Rode, Rafael; Figueiredo Filho, Afonso; Machado, Sebastião do Amaral; Galvão, FranklinEste estudo teve como objetivos a determinação de grupos florísticos, a discriminação e avaliação de espécies importantes na composição florística em duas áreas de pesquisa localizadas na Floresta Nacional de Irati, Estado do Paraná. Uma área com 10 ha foi instalada em um povoamento de Araucária implantado há 60 anos (área A), onde espécies arbóreas se estabeleceram, enquanto que outra de 25 ha foi instalada em...
Influence of anthropic impacts on remnants of Ombrophilous Mixed Forest in Sant...
Liebsch, Dieter; Maçaneiro, João Paulo de; Marcon, Amanda Koche; Galvão, FranklinSelective cutting and pastures are common activities in the Ombrophilous Mixed Forest, which is part of the Atlantic Rain Forest Biome. Our goal was to relate floristic composition and structure unit with its past use. Adult and juvenile wood species of twelve forest fragments were evaluated in Santa Catarina State. Fragments with less anthropic impacts showed greater richness and diameter range, and lower dens...
Floristic composition and distribution of soil seed bank in Subtropical Ombroph...
Silva-Weber, Ariadne Josiane Castoldi; Nogueira, Antonio Carlos; Carpanezzi, Antonio Aparecido; Galvão, Franklin; Weber, Saulo HenriqueIn this research it was evaluated the potential of the soil seed bank in a remaining of Subtropical Ombrophilous Alluvial Forest (Araucaria Forest), by quali-quantitative analysis of seed germination. Additionally it was tested the occurrence of seasonal variation of the soil seed bank. The forest remaining located in Araucaria county, Parana State, Brazil, and it is influenced by Barigui river, affluent of Igu...
Auto-ecology of Guadua aff. paraguayana (Poaceae)
Galvão, Franklin; Augustin, Cátia Regina; Curcio, Gustavo Ribas; Domanowski, Bruno Polli; Kozera, Carina; Sawczuk, Alison Tadeu; Bonnet, AnneteBamboos are agents of natural remediation, but its outbreak in an already established landscape mayhave an intense repercussion, completely changing the flora of the area. A study to determine the effects of the presence of Guadua aff. paraguayana Döll (Poaceae) found in the last remnants of the riparian forest in the areas of permanent preservation of the Wildlife Refuge of Rio Tibagi - a conservation unit in...
Dynamics of treefall gaps in a harvested forest in Misiones, Northern Argentine
Bulfe, Nardia Maria Luján; Galvão, Franklin; Figueiredo Filho, Afonso; Donagh, Patricio MacThis work evaluates the diameter growth of trees species of artificial gaps per ecological groups in a harvested forest considering two systems of harvest. The study was carried out in the Reserva de Biósfera Yabotí, in Misiones, Argentina. Fifteen permanent plots were established, each one with 4 hectares with effective area of measurement of one hectare. The three treatments were: conventional logging, reduce...
Horizontal structure of arboreal community under an Araucaria angustifolia stan...
Rode, Rafael; Figueiredo Filho, Afonso; Galvão, Franklin; Machado, Sebastião do AmaralThe horizontal structure of the arboreal community under an Araucaria angustifolia stand with 60 years and a Mixed Ombrophyllous Forest in National Forest of Irati, Parana State - Brazil, were compared. In both areas were established permanent plots of 1 ha (100 m x 100 m): 10 plots (10 ha) in the A. angustifolia stand and 25 plots (25 ha) in the natural forest. All of the individuals with dbh above 10 centimet...
Environmental restoration with forest trees in the Southern State of Parana gra...
Sousa, Letícia Penno de; Angelo, Alessandro Camargo; Curcio, Gustavo Ribas; Bonnet, Annete; Galvão, FranklinHuman development activities as water reservoir construction have great impact on the vegetation, thus changing its floristic, as well as its structure and ecology functions. Parana Pine Forest alongside with grasslands have been highly modified and in particular to the last one, there are few works related to its restoration. In the border of Irai water reservoir (Metropolitan Region of Curitiba, PR), where oc...
Floodplain restoration on Itajaí-Açu river, Santa Catarina State, Brazil: survi...
Pozzobon, Maurício; Curcio, Gustavo Ribas; Uhlmann, Alexandre; Galvão, Franklin; Zimmer, EduardoThe variation of soil attributes along with peculiarities of riverine ecosystem process, determines strong influence on the vegetation distribution in these environments. The restoration strategies of riverine vegetation need to observe these peculiarities and, in this case, choosing of appropriate species is a key element to initiate the process of establishment of a functional community. The present study ai...
