Resumo: | The present work was carried out in a semideciduous montane forest area of the Natural Reserve of the Natural Patrimony (RPPN) Pedra D'anta - PE, with the objective of evaluating structural alterations in the vegetation, in a local fragment scale, and if these are explained by topographic variation (top, slope and valley), by altitude and soil characteristics. A total of 50 continuous plots of 20x10 m, distributed under the top conditions, were placed and evaluated for all individuals with breast height diameter (DAP) ≥ 5. Measurements were collected / collected in each sample unit as follows: altitude, biomass of Litter cover, canopy cover and composite soil samples. The total density recorded for the fragment was 1,653 ind.ha-1 and a total basal area of 25.33 m².ha-1. The topographic and topographic conditions differed significantly for the number of individuals, height and diameter, with the two largest results in the slope diameter. A canopy cover did not differ between conditions. Of the soil variables only the aluminum and magnesium contents were influenced by the altitude variations. A litter biomass ranged from 3.38 t / ha (valley) to 4.45 t / ha (slope). As multiple linear regression analyzes indicated that among the structural aspects of the vegetation a distribution of the number of individuals varied as a function of altitude, pH and calcium; A diameter in relation to litter biomass and an altitude; And the height and cover variations with the analyzed abiotic variables. In view of the results, it is concluded that in fragment scale or altitude increase, associated with topography, it exerts a positive effect in density, negative in relation to the diameter and indifferent to a height of the plants and canopy cover; In addition to being a predictor of changes in soil characteristics. |

Foram plotadas 50 parcelas contínuas de 20x10 m, distribuídas nas condições de topo, encosta e vale e incluídos todos os indivíduos com diâmetro a altura do peito (DAP) ≥ 5. Foram mensuradas/coletadas em cada unidade amostral as seguintes variáveis ambientais: altitude, biomassa de serrapilheira, cobertura do dossel e amostras compostas de solo. A densidade total registrada para o fragmento foi de 1.653 ind.ha-1 e a área basal total de 25,33 m².ha-1. As condições topográficas de topo e encosta diferiram significativamente para o número de indivíduos, altura e diâmetro, sendo os dois primeiros maiores no topo e o diâmetro na encosta. A cobertura do dossel não diferiu entre condições. Das variáveis do solo apenas os teores de alumínio e magnésio foram influenciados pelas variações de altitude presentes no fragmento. A biomassa de serrapilheira variou de 3,38 t/ha (vale) a 4,45 t/ha (encosta). As análises de regressão linear múltipla indicaram que entre os parâmetros estruturais da vegetação a distribuição do número de indivíduos variou em função da altitude, do pH e do cálcio; a de diâmetro em relação a biomassa de serrapilheira e a altitude; e as variações de altura e cobertura do dossel não tiveram relação com as variáveis abióticas analisadas. Diante dos resultados, conclui-se que em escala de fragmento o aumento de altitude, associado à topografia, exerce um efeito positivo na densidade, negativo em relação ao diâmetro e indiferente para a altura das plantas e cobertura do dossel; além de ser preditora de alterações nas características do solo.Submitted by Mario BC (mario@bc.ufrpe.br) on 2018-06-07T15:50:54Z No. of bitstreams: 1 Renato Magnum Tavares Costa.pdf: 1701983 bytes, checksum: d2360d24c932b61314c2cabdc153fa53 (MD5)Made available in DSpace on 2018-06-07T15:50:54Z (GMT).

The present work was carried out in a semideciduous montane forest area of the Natural Reserve of the Natural Patrimony (RPPN) Pedra D'anta - PE, with the objective of evaluating structural alterations in the vegetation, in a local fragment scale, and if these are explained by topographic variation (top, slope and valley), by altitude and soil characteristics. A total of 50 continuous plots of 20x10 m, distributed under the top conditions, were placed and evaluated for all individuals with breast height diameter (DAP) ≥ 5. Measurements were collected / collected in each sample unit as follows: altitude, biomass of Litter cover, canopy cover and composite soil samples. The total density recorded for the fragment was 1,653 ind.ha-1 and a total basal area of 25.33 m².ha-1. The topographic and topographic conditions differed significantly for the number of individuals, height and diameter, with the two largest results in the slope diameter. A canopy cover did not differ between conditions. Of the soil variables only the aluminum and magnesium contents were influenced by the altitude variations. A litter biomass ranged from 3.38 t / ha (valley) to 4.45 t / ha (slope). As multiple linear regression analyzes indicated that among the structural aspects of the vegetation a distribution of the number of individuals varied as a function of altitude, pH and calcium; A diameter in relation to litter biomass and an altitude; And the height and cover variations with the analyzed abiotic variables. In view of the results, it is concluded that in fragment scale or altitude increase, associated with topography, it exerts a positive effect in density, negative in relation to the diameter and indifferent to a height of the plants and canopy cover; In addition to being a predictor of changes in soil characteristics. |
