The relation among basal area, light and functional characteristics variation is still an unexplored issue, especially in rainforests with different disturbance regimes. The following hypotheses were tested: 1) basal area of arboreal plants and light availability is a good predictor of the functional characteristics, once it is believed that in forest environments with a lower basal area and much light, functional characteristics values linked to the fast light resources utilization are found in leaves, stem and roots; 2) environments where there is greater light availability, the standard deviation values of the leaf characteristics will be greater. The functional characteristics values were not influenced by the geographic distance (spatial autocorrelation) neither by the species phylogeny. The prediction that in the areas with the lower basal area, values of characteristics associated with the rapid use of the light resource were confirmed for five characteristics: dry leaf matter (LMDC), stem (SDMC) and root (RDMC), the density of wood stem (WDC) and root (WDR). Significant investment was not found in structural carbon (greater dry matter values of leaf and wood) in environments with the greater basal area. It is considered that in urban fragments the disturbances are frequent, it is possible to suppose that plants with lower values of LDMC, DWC, DWR, SDMC, and RDMC have also "established" in the two areas with a greater basal area. It is concluded that in fragments in urban rainforest studied, perturbations may change the succession path due to population dynamics, especially in the area with more abundant light availability and lesser basal area (A4<AB). the study suggests that this greater light input in the A4<AB environment, due to the greater perturbations, would lead plants with the strategy of using a slow resource, favoring those with fast use of the resource, and as a result, there would be less variability of the leaf characteristics in A4<AB. The basal area and light intensity are not good predictors of variations of functional characteristics in the urban fragments studied.

The functional characteristics of plants can be used to understand the changes of vegetation under different environmental pressures, since during the process of succession, the species deal with variations of luminosity, an important resource for the regeneration and growth of plants in humid tropical forests. From the perspective that along the succession there is variation of light availability and that leaf characteristics such as specific leaf area, chlorophyll content and leaf dry matter content are more plastic in groups linked to the rapid acquisition of the resource at the beginning of the succession, it was tested the hypothesis that at the beginning of the succession, where there is greater availability of light, leaf characteristics would be more plastic for the acquisitive group. It was initially found that the geographic distances did not influence the values ​​of the variability indices of the groups, which allows to infer that the distance between the areas does not interfere in the variability of the leaf characteristics. To answer the hypothesis that at the beginning of the succession, in which there is greater light availability, the leaf characteristics would be more plastic for the purchasing group than for the conservative ones, a simple linear regression analysis (ARLS) was performed in the indices of variability for the groups (acquisitive and conservative) and abiotic factor (light) in each area of ​​occurrence. However, the hypothesis that at the beginning of the succession, where there is greater light availability, the characteristics of the leaf would be more plastic for the species was rejected for the species acquisitive, since all indices were reduced for the purchasing group. It is important to take into account that the variation of leaf characteristics as a function of the light availability in an urban tropical fragment is different from what occurs in the classic succession commonly reported, pointing out that possible disturbances caused by the surroundings are the main agents of the functional structure of the community.

The scarcity of information on the socioeconomic of non-wood forest products in Maceio acts as an obstacle to forest conservation and also to the development of market. In this way, the aim of this work was to evaluate the non-wood forest products (NWFPs) market in the municipality of Maceió, AL. The study was carried out in NWFP stores in the city of Maceió, AL, Brazil, between September and October 2018. Data were collected through a semi-structured questionnaire containing 9 closed questions and 11 open questions, totaling 20 questions, which were analyzed in a descriptive way and statistics. Among the interviews, there was a predominance of the female gender in the market (78%). In which, the most cited species were cinnamon (Cinnamomum verum) with 88.89%; aroeira (Schinus terebinthifolius) with 66.67%; followed by barbatimao (Stryphnodendron barbatimam Mart.) cited 66.67%. The boldo (Peumus boldus) was cited 55.56%; followed by rosemary (Rosmarinus officinalis), clove (Syzygium aromaticum) and laurel (Laurus nobilis), which presented 44.44% of the citations. It can be seen that 65% of products fall under the category of medicinal use, 15% in the category of food use and 10% are used as cosmetics. Among the most used parts, it was observed that the majority of the products are leaves (36.9%) and barks (32.6%). When questioned about the origin of their products, 77.7% of those interviewed said they bought them for resale. The other 22.3% claimed that in addition to buying them, they also collect them. This trade has proven very effective, due to its great potential for social inclusion and economic incentive in the municipality.

Adenanthera pavonina L. (Piriquiti) is a pioneer Brazilian forest species belonging to the botanical family Fabaceae of characteristics that make it of important economic interest both for its high timber potential, as for ecology and uses as Ornamental plant. Some factors may be limiting to the germination of plant seeds, especially forest, conditions of salt stress can be one of the factors. The present study aimed to show the germination behavior of A. Pavonina when placed under conditions of saline stress, in different levels of NaCl salt, to point to future studies other possibilities of use for the species. The maximum limiting saline concentration found was 2.0% of sodium chloride, below this concentration does not hear statistical difference in the percentage of germination, however, the increase in the saline concentration up to the maximum limit, negatively affected the Germination velocity, levels above 2.0% were not observed germination. RESUMOAdenanthera pavonina L. (Piriquiti) é uma espécie florestal brasileira pioneira, pertencente à família botânica Fabaceae, de características que o tornam de importante interesse econômico, tanto pelo seu alto potencial madeireiro, quanto pela ecologia e usos como planta ornamental. Alguns fatores podem estar limitando a germinação de sementes de plantas, principalmente florestas, condições de estresse salino podem ser um dos fatores. O presente estudo teve como objetivo mostrar o comportamento germinativo de A. Pavonina quando submetido a condições de estresse salino, em diferentes níveis de sal NaCl, para apontar para estudos futuros outras possibilidades de uso para a espécie. A concentração salina limitante máxima encontrada foi de 2,0% de cloreto de sódio, abaixo dessa concentração não ouve diferença estatística na porcentagem de germinação, no entanto, o aumento da concentração salina até o limite máximo afetou negativamente a velocidade de germinação, níveis acima de 2,0 % não foram observadas germinação.Palavras-chave: cloreto de sódio, reflorestamento, espécies arbóreas.
