-(Diversity and structure of the lower strata in two successional stages in a subtropical forest, Southern Brazil). Currently, in Paraná State, forest remnants in advanced successional stages account for less than 1% of its original area. This study compared the understory community across different successional stages of the Araucaria Forest in southern Brazil. Forest remnants, one in intermediate and another in advanced stage of natural regeneration were selected, and a total of 38 plots of 5 × 5 m were sampled. Individuals reaching at least 2 m high or having circumference up to 15 cm at height 1.3 m above the soil surface were measured and identified. In the forest at an intermediate stage, 68 species were recorded being mostly light-dependent, with Nectandra megapotamica as the most important species. On the other hand, at an advanced stage, less species were found (52 species) but most individuals were shade-tolerant, with Rudgea jasminoides as the most important species. These differences are most probably caused because of the canopy density of each fragment. As the comparison with other studies is impaired due to different plot sizes and inclusion criteria, we suggest the standardization to improve knowledge and support biodiversity conservation of the southern tropical forest of Brazil. Keywords: Ecology, growth forms, phytosociological survey, Paraná State RESUMO -(Riqueza, composição e estrutura da comunidade arbustivo-regenerante em diferentes estágios sucessionais de uma Floresta Subtropical do Brasil). Atualmente, os remanescentes em estágio avançado de sucessão no Estado do Paraná somam menos de 1% de sua área original. Este trabalho comparou a composição e estrutura da comunidade de sub-bosque em diferentes estágios sucessionais de Floresta Ombrófila Mista. Foram selecionados dois remanescentes florestais, um em estágio médio e outro em estágio avançado de regeneração natural, onde foram amostradas 38 parcelas de 5 × 5 m. Foram mensurados indivíduos com altura superior a 2 m e perímetro a 1,30 m de altura do solo ≤ 15 cm. Na área em estágio médio foram registradas 68 espécies, representadas por espécies secundárias com exigência de luz, destacando-se Nectandra megapotamica com os maiores valores de importância. Para área em estágio avançado foram registradas 52 espécies representadas por indivíduos tardios tolerantes à sombra, com destaque para Rudgea jasminoides. Como a comparação com outros estudos é prejudicada pelos diferentes tamanhos de parcelas e/ou os critérios de inclusão, sugerimos que uma padronização é necessária para melhorar o conhecimento e apoiar a conservação da biodiversidade das florestas tropicais da região Sul do Brasil.

“…Inga edulis occurs in diverse phytogeographical domains in Brazil, including the Amazon, Caatinga, Cerrado, and Atlantic Forest (Possette and Rodrigues, 2010;Souza et al, 2011;Garcia and Fernandes, 2015). Despite its wide occurrence and its potential for use in agroforestry systems and in recovery of degraded or altered areas, there are no bacterial strains recommended for these leguminous plants.…”

Inga edulis Mart. is a leguminous tree adapted to acidic and low-fertility soils that establishes symbioses with nitrogen (N)-fixing bacteria. The identification of effective bacteria in biological N fixation may bolster the use of I. edulis in degraded or modified areas and agroforestry systems. Therefore, the aims of this study were evaluation of the symbiotic effectiveness of eight strains of the Bradyrhizobium genus native to Roraima in Inga edulis plants, and in vitro evaluation of the ability of the eight strains of Bradyrhizobium to develop plant growth-promoting characteristics. Determination of symbiotic effectiveness was carried out via three experiments: the first in a greenhouse in pots with a sterile substrate; the second in a greenhouse in pots containing non-sterile soil; and the third in a nursery in bags with a non-sterile substrate. Twelve treatments were evaluated: inoculation with eight strains of Bradyrhizobium ingae (ERR 490, ERR 492, ERR 493, ERR 494 T , ERR 496, ERR 497, ERR 498, and ERR 569); inoculation with two strains indicated for Inga marginata, BR 6609 and BR 6610 (positive controls); no inoculation but with mineral N; and neither inoculation nor mineral N. All of the experiments were conducted in a completely randomized design with four replicates. The first experiment was conducted for 60 days, and the other experiments were conducted for 100 days. For all of the experiments, the number of nodules, nodule dry matter, root dry matter, shoot dry matter, number of leaflets, plant height, stem diameter, total N in the shoots, root/shoot dry matter ratio, Dickson's quality index, relative effectiveness, and the Pearson correlation between the variables under study were evaluated. The strains were also evaluated by their ability to solubilize calcium and aluminum phosphates and to produce indolic compounds. The results showed that B. ingae strains were effective in biological N fixation, especially the ERR 493, ERR 498, and ERR 569 strains. These strains increased the production of shoot dry matter and total N and exhibited relative effectiveness higher than 100 % in all of the experiments. The B. ingae strains were also able to solubilize calcium and aluminum phosphates, despite their synthesis of indolic compounds. Thus, the strains of B. ingae can be used for inoculation in the production of I. edulis seedlings.
