“…2) have yielded results consistent with those we obtained for the FSM, the index we obtained for the INP was lower than those reported in all of the studies we reviewed. The same pattern was observed for the evenness index for the INP, which was lower in the present study than in other studies, whereas the evenness index for the FSM was consistent with those of the same studies (Ivanauskas et al 1999;Bianchini et al 2003;Jurinitz & Jarenkov 2003;Silva et al 2004;Costa-Filho et al 2006;Prado-Júnior et al 2011). Connell (1978) proposed that higher species diversity is maintained under intermediate levels of disturbance.…”

Structure and floristic diversity of remnant semideciduous forest under varying levels of disturbance

2014

The perturbation of Neotropical forests generates large disturbances in biological communities. The species that suffer least from the resulting habitat fragmentation are the pioneers, because they possess greater ability to inhabit disturbed environments. Therefore, it is expected that species diversity will be greater in areas subjected to intermediate disturbance, such as the opening of gaps, because a large number of pioneer species will develop and coexist with species of more advanced successional stages. This study aimed to compare two forest remnants that differed in size and disturbance intensity, in order to determine the effects of disturbances on species diversity and the size ratios of individual trees. This was accomplished with comparative analyses of diversity, richness and diameter ratios obtained for 10 plots at two semideciduous forest sites. We recorded a total of 85 species, of which 70 were in the private nature reserve Fazenda Santa Maria, 58 were in Iguaçu National Park, and 43 were at both sites. Diversity was greater in the more disturbed remaining forest, because this area showed higher species richness, which is in accordance with some premises of the intermediate disturbance theory. There was also an increase in the number of pioneer individuals, and the less disturbed area showed individuals with larger diameters, which is likely attribu table to the removal of large individuals from the more disturbed area during the anthropogenic process of forest modification.

“…Also in the upper region of the diagram, C. americana, L. nitidus and M. stipitatum were associated with high humidity in SSF Submontana regions, which were also observed by Scipioni et al (2013) in an Alluvial Submontana FED. Costa et al (2006) found high densities of B. densiflora in a Fluvic Neossol, corroborating the distribution of this species in the Park.…”

“…Del Quiqui et al (2007) also found in a plateau of SSF Submontana, in the north of Paraná, H. balansae and A. polyneuron. Costa et al (2006), in turn, cited A. polyneuron and B. riedelianum under the same environmental conditions. M. frondosus also appears in the upper portion of the diagram, slightly to the right due to the higher occurrence in the intermediate altitude regions (450 to 650 m).…”

Effect of Environmental Variables in the Distribution of Tree Species in the Iguaçu National Park

et al. 2018

The knowledge of the environmental variable seffect on the distribution of tree species is of great importance, since it contributes to a greater efficiency on the management of forests and on the conservation of degraded areas. In order to identify these effects on native species from the western region of Paraná, 21 plots of 2,000 m2 were installed in the Iguaçu National Park. The plots were distributed along the altitude gradient, between 150 and 750 m, and in different positions of the drainage ramps, from the river banks to the plateau regions. After the data processing carried out by Canonical Correspondence Analysis, it was identified species that are distributed in the vegetation according to the variations of altitude, humidity, fertility, saturation by aluminum and soil clay content. Some species presented tolerance to the environmental variations, a typical characteristic of species of wide geographic occurrence.

“…O elevado valor de importância apresentado por Calophyllum brasiliense se deveu à presença de indivíduos de grande porte, resultando em altos valores de dominância. Há estudos em que a espécie foi uma das de maior valor de importância em ambientes de restinga não inundável (Guedes et al, 2006) ou em áreas ripárias de Floresta Estacional Semidecidual (Toniato et al, 1998;Costa Filho et al, 2006;OliveiraFilho et al, 1994) ou mesmo em caxetais (Galvão et al, 2002), em razão, justamente, da sua dominância.…”

O estudo foi realizado em um fragmento de Floresta Estacional Semidecidual (Misiones, Argentina), com o objetivo de analisar as variáveis fitossociológicas das espécies arbóreas, por meio da estratificação da área de acordo com a geomorfologia. Inicialmente, baseando-se na declividade e por meio de fotointerpretação, a área foi compartimentalizada em: planície, encostas com declividade média, encostas com declividade alta e topo. Dentro de cada compartimento, foram alocados três conglomerados compostos de quatro subunidades de 100 m2, totalizando 48 subunidades, nas quais foram incluídas todas as árvores com circunferência à altura do peito ≥ 10 cm, sendo também medidas a profundidade do solo e a declividade. Foram amostradas 72 espécies, 59 gêneros e 31 famílias. Foi possível detectar variações das espécies e dos valores de importância, obtidos de acordo o gradiente topográfico. Na Análise de Correspondência Canônica, os valores de cobertura das espécies mostraram ter uma correlação significativa com os parâmetros profundidade de solo e declividade.
