Resumo: | The objective of this study was to understand the ecology and biometric modeling of the tree ferns of the species Alsophila setosa, Cyathea corcovadensis, Cyathea phalerata and Dicksonia sellowiana. The interaction of soil attributes with the presence of arborescent ferns, their phenology, phytosociology, ecological indexes, spatial distribution and dynamics, adjustment of hypsometry equations, volumetry and tapering functions and the quantification of the biomass stock were evaluated in the Irati National Forest (PR), in two areas: Area 1 (native forest) and Area 2 (Araucária plantation). A matrix of soil attributes with a vegetational matrix was used for the analysis of canonical correspondence. In phenology (vegetative and reproductive), 10 individuals from A. setosa, C. phalerata, D. sellowiana, and nine individuals from C. corcovadensis were selected, with monthly monitoring in the period 2016-2019. The increase in total height was measured annually. Synchrony rates and correlations between phenological variables and environmental variables were evaluated. In phytosociology, DBH and height were measured in tree ferns, as well as other qualitative variables to calculate density, dominance, frequency and importance value, in addition to the ecological indexes (Shannon-Wiener, Pielou, Jaccard and Sorensen). To analyze the spatial distribution, the Morisita, Payandeh and Hazen indices were used. In the 2014-2017 dynamics studies, growth, ingrowth and mortality were assessed at the species level for diameter, crosssectional area and total height. In biometric modeling (hypsometry, volumetry and tapering functions), rigorous cubing data from 35 individuals from A. setosa and 35 from D. sellowiana were used, followed by extrapolation to the population. In biomass, 30 individuals of A. setosa, 30 of D. sellowiana and 30 individuals for the genus Cyathea were selected. The tree ferns were separated into two components, these being the caudex and frond (pinna and rachis), which after obtaining the green weight in the field, were taken to the greenhouse with forced ventilation at 70 ° C until they reached constant weight. The soil attributes showed greater discriminating power for the number of individuals of C. corcovadensis (higher percentages of saturation by aluminum and cation exchange capacity) and basal area of D. sellowiana (lower percentages of silt, magnesium, aluminum, potassium and phosphor). Regarding phenology, for A. setosa the croziers were produced between October and November and for their reproductive phase there was little synchrony for the immature sporangia and there was no synchrony for the closed sporangia and releasing spores. C. corcovadensis produced croziers between October and November, for its reproductive phase there was little synchrony. C. phalerata produced croziers from September to November, its reproductive phase was highly synchronized. For D. sellowiana, the croziers were produced from September to December, and in the reproductive phase there was no synchrony. About phytosociology, in Area 1 A. setosa presented 1539 ind.ha-1 , basal area of 14.3 m².ha- ¹ and the largest IVI, D. sellowiana had 82 ind.ha- ¹ and 5.41 m².ha - ¹ basal area, C. corcovadensis had 1 ind.ha- ¹ and basal area of 0.04 m².ha- ¹, C. phalerata had 19 ind.ha- ¹ and 0.35 m².ha- ¹. In Area 2 A. setosa had 601 ind.ha- ¹, with basal area of 5.23 m².ha- ¹ and second largest IVI, D. sellowiana had 14 ind.ha- ¹ and 0.39 m².ha- ¹, C. corcovadensis had 4 ind.ha- ¹ and 0.08 m².ha- ¹, C. phalerata had 2 ind.ha- ¹ and 0.02 m².ha- ¹ of basal area. Regarding ecological indexes, Area 1 has greater diversity. The spatial distribution of the species was aggregated. Regarding the dynamics, the percentage of ingrowth and mortality that was most expressive was Cyathea spp, with the highest ingrowth. In biometric modeling, for A. setosa the volume estimated by the Schumacher-Hall model was 60.015 m³.ha-1 for Area 1, and 38.510 m³.ha-1 for Area 2. For D. sellowiana, the model of Henricksen was the most adequate to estimate the total height, and the straight line model to estimate the commercial height, with the total volume estimated by the Stoate model, being 17.971 m³.ha-1 for Area 1 and 1.306 m³.ha-1 , and the commercial volume also estimated by the Stoate model, at 14.498 m³.ha-1 for Area 1 and 1.039 m³.ha-1 for Area 2. For the tapering functions of D. sellowiana, a 5th degree polynomial demonstrated better performance. In biomass A. setosa had a total biomass of 8,113 t.ha-1 for Area 1, in Area 2 it presented 2,684 t.ha-1 . Cyathea spp showed a total biomass of 0.177 t.ha-1 for Area 1, in Area 2 it had 0.0305 t.ha-1 . Dicksonia sellowiana had a total biomass of 1,495 t.ha-1 for Area 1 and in Area 2 it had 0.149 t.ha-1. |

Avaliou-se a interação dos atributos do solo com a presença das samambaias arborescentes, sua fenologia, a fitossociologia, índices ecológicos, distribuição espacial e a dinâmica, ajuste de equações de hipsometria, volumetria e funções de afilamento e a quantificação do estoque de biomassa na Floresta Nacional de Irati (PR), em duas áreas: Área 1 (floresta nativa) e Área 2 (plantio de Araucárias). Utilizou-se uma matriz de atributos do solo com uma matriz vegetacional para a análise de correspondência canônica. Na fenologia (vegetativa e reprodutiva) foram selecionados 10 indivíduos de A. setosa, C. phalerata, D. sellowiana, e nove indivíduos de C. corcovadensis, com acompanhamento mensal no período de 2016- 2019. O incremento em altura total foi aferido anualmente. Foram avaliadas as taxas de sincronia e das correlações das variáveis fenológicas com variáveis ambientais. Na fitossociologia, nas samambaias arborescentes foram mensurados o DAP e altura, além de outras variáveis qualitativas para calcular densidade, dominância, frequência e valor de importância, além de calculados os índices ecológicos (Shannon-Wiener, Pielou, Jaccard e Sorensen). Para analisar a distribuição espacial foram utilizados os índices Morisita, Payandeh e Hazen. Nos estudos da dinâmica de 2014-2017, avaliaram-se o crescimento, ingresso e mortalidade em nível de espécie para diâmetro, área transversal e altura total. Na modelagem biométrica (hipsometria, volumetria e funções de afilamento), utilizou-se dados de cubagem rigorosa de 35 indivíduos de A. setosa e 35 de D. sellowiana, seguida da extrapolação para a população. Na biomassa, foram selecionados 30 indivíduos de A. setosa, 30 de D. sellowiana e 30 indivíduos para o gênero Cyathea. As samambaias arborescentes foram separadas em dois componentes, sendo estes cáudice e fronde (pina e raque), que após obtido o peso verde em campo, foram levadas a estufa com ventilação forçada a 70° C até atingirem peso constante. Os atributos do solo demostraram maior poder discriminante para o número de indivíduos de C. corcovadensis (maiores porcentagens de saturação por alumínio e capacidade de troca de cátions) e área basal de D. sellowiana (menores porcentagens de silte, magnésio, alumínio, potássio e fósforo). Sobre a fenologia, para A. setosa os báculos foram produzidos entre outubro e novembro e para sua fase reprodutiva houve pouca sincronia para os esporângios imaturos e não houve sincronia para os esporângios fechados e liberando esporos. C. corcovadensis produziu báculos entre outubro e novembro, para sua fase reprodutiva houve pouca sincronia. C. phalerata produziu báculos de setembro a novembro, sua fase reprodutiva teve alta sincronia. Para D. sellowiana os báculos foram produzidos de setembro a dezembro, sendo que na fase reprodutiva não houve sincronia. Sobre a fitossociologia, na Área 1 A. setosa apresentou 1539 ind.ha-1 , área basal de 14,3 m².ha- ¹ e maior IVI, D. sellowiana teve 82 ind.ha- ¹ e 5,41 m².ha- ¹ de área basal, C. corcovadensis teve 1 ind.ha- ¹ e área basal de 0,04 m².ha- ¹, C. phalerata teve 19 ind.ha- ¹ e 0,35 m².ha- ¹. Na Área 2 A. setosa teve 601 ind.ha- ¹, área basal de 5,23 m².ha- ¹ e segundo maior IVI, D. sellowiana teve 14 ind.ha- ¹ e 0,39 m².ha- ¹, C. corcovadensis teve 4 ind.ha- ¹ e 0,08 m².ha- ¹, C. phalerata teve 2 ind.ha- ¹ e 0,02 m².ha- ¹ de área basal. Sobre os índices ecológicos, a Área 1 possui maior diversidade. A distribuição espacial das espécies foi agregada. Sobre a dinâmica, o percentual de ingressos e mortalidade mais expressivo foi Cyathea spp, sobressaindo os ingressos. Na modelagem biométrica, para A. setosa o volume estimado pelo modelo de Schumacher-Hall foi de 60,015 m³.ha-1 para a Área 1, e 38,510 m³.ha-1 para a Área 2. Para D. sellowiana, o modelo de Henricksen foi o mais adequado para estimar a altura total, e o modelo da linha reta para estimar a altura comercial, sendo o volume total estimado pelo modelo de Stoate, de 17,971 m³.ha-1 para Área 1 e 1,306 m³.ha-1 , e o volume comercial também estimado pelo modelo de Stoate, em 14,498 m³.ha-1 para a Área 1 e 1,039 m³.ha-1 para a Área 2. Para as funções de afilamento de D. sellowiana, polinômio de 5° grau demonstrou melhor desempenho. Na biomassa A. setosa teve biomassa total de 8,113 t.ha-1 para a Área 1, na Área 2 apresentou 2,684 t.ha-1 . Cyathea spp apresentou biomassa total de 0,177 t.ha-1 para a Área 1, na Área 2 teve 0,0305 t.ha-1 . Dicksonia sellowiana teve biomassa total de 1,495 t.ha-1 para a Área 1 e na Área 2 teve 0,149 t.ha-1.Submitted by Fabiano Jucá (fjuca@unicentro.br) on 2021-02-17T13:40:05Z No. of bitstreams: 1 Jocasta Lerner.pdf: 1872164 bytes, checksum: a2ab6888b8222220f39302247ed0d631 (MD5)Made available in DSpace on 2021-02-17T13:40:05Z (GMT).

description |
The objective of this study was to understand the ecology and biometric modeling of the tree ferns of the species Alsophila setosa, Cyathea corcovadensis, Cyathea phalerata and Dicksonia sellowiana. The interaction of soil attributes with the presence of arborescent ferns, their phenology, phytosociology, ecological indexes, spatial distribution and dynamics, adjustment of hypsometry equations, volumetry and tapering functions and the quantification of the biomass stock were evaluated in the Irati National Forest (PR), in two areas: Area 1 (native forest) and Area 2 (Araucária plantation). A matrix of soil attributes with a vegetational matrix was used for the analysis of canonical correspondence. In phenology (vegetative and reproductive), 10 individuals from A. setosa, C. phalerata, D. sellowiana, and nine individuals from C. corcovadensis were selected, with monthly monitoring in the period 2016-2019. The increase in total height was measured annually. Synchrony rates and correlations between phenological variables and environmental variables were evaluated. In phytosociology, DBH and height were measured in tree ferns, as well as other qualitative variables to calculate density, dominance, frequency and importance value, in addition to the ecological indexes (Shannon-Wiener, Pielou, Jaccard and Sorensen). To analyze the spatial distribution, the Morisita, Payandeh and Hazen indices were used. In the 2014-2017 dynamics studies, growth, ingrowth and mortality were assessed at the species level for diameter, crosssectional area and total height. In biometric modeling (hypsometry, volumetry and tapering functions), rigorous cubing data from 35 individuals from A. setosa and 35 from D. sellowiana were used, followed by extrapolation to the population. In biomass, 30 individuals of A. setosa, 30 of D. sellowiana and 30 individuals for the genus Cyathea were selected. The tree ferns were separated into two components, these being the caudex and frond (pinna and rachis), which after obtaining the green weight in the field, were taken to the greenhouse with forced ventilation at 70 ° C until they reached constant weight. The soil attributes showed greater discriminating power for the number of individuals of C. corcovadensis (higher percentages of saturation by aluminum and cation exchange capacity) and basal area of D. sellowiana (lower percentages of silt, magnesium, aluminum, potassium and phosphor). Regarding phenology, for A. setosa the croziers were produced between October and November and for their reproductive phase there was little synchrony for the immature sporangia and there was no synchrony for the closed sporangia and releasing spores. C. corcovadensis produced croziers between October and November, for its reproductive phase there was little synchrony. C. phalerata produced croziers from September to November, its reproductive phase was highly synchronized. For D. sellowiana, the croziers were produced from September to December, and in the reproductive phase there was no synchrony. About phytosociology, in Area 1 A. setosa presented 1539 ind.ha-1 , basal area of 14.3 m².ha- ¹ and the largest IVI, D. sellowiana had 82 ind.ha- ¹ and 5.41 m².ha - ¹ basal area, C. corcovadensis had 1 ind.ha- ¹ and basal area of 0.04 m².ha- ¹, C. phalerata had 19 ind.ha- ¹ and 0.35 m².ha- ¹. In Area 2 A. setosa had 601 ind.ha- ¹, with basal area of 5.23 m².ha- ¹ and second largest IVI, D. sellowiana had 14 ind.ha- ¹ and 0.39 m².ha- ¹, C. corcovadensis had 4 ind.ha- ¹ and 0.08 m².ha- ¹, C. phalerata had 2 ind.ha- ¹ and 0.02 m².ha- ¹ of basal area. Regarding ecological indexes, Area 1 has greater diversity. The spatial distribution of the species was aggregated. Regarding the dynamics, the percentage of ingrowth and mortality that was most expressive was Cyathea spp, with the highest ingrowth. In biometric modeling, for A. setosa the volume estimated by the Schumacher-Hall model was 60.015 m³.ha-1 for Area 1, and 38.510 m³.ha-1 for Area 2. For D. sellowiana, the model of Henricksen was the most adequate to estimate the total height, and the straight line model to estimate the commercial height, with the total volume estimated by the Stoate model, being 17.971 m³.ha-1 for Area 1 and 1.306 m³.ha-1 , and the commercial volume also estimated by the Stoate model, at 14.498 m³.ha-1 for Area 1 and 1.039 m³.ha-1 for Area 2. For the tapering functions of D. sellowiana, a 5th degree polynomial demonstrated better performance. In biomass A. setosa had a total biomass of 8,113 t.ha-1 for Area 1, in Area 2 it presented 2,684 t.ha-1 . Cyathea spp showed a total biomass of 0.177 t.ha-1 for Area 1, in Area 2 it had 0.0305 t.ha-1 . Dicksonia sellowiana had a total biomass of 1,495 t.ha-1 for Area 1 and in Area 2 it had 0.149 t.ha-1. |
