Two experiments were conducted in a greenhouse in a completely randomized design with three replications. The first experiment corresponded to applications of desiccation with treatments: glyphosate (1,080 g ha-1); glyphosate + 2,4-D (1,080 + 670 g ha-1); glyphosate + carfentrazone-ethtyl (1,080 + 20 g ha-1); glyphosate + flumioxazin (1,080 + 25 g ha-1); glyphosate + saflufenacil (1,080 + 35 g ha-1); glyphosate + chlorimuron-ethyl (1,080 + 12.5 g ha-1); diuron + paraquat (300 + 600 g ha-1); and the control without application. In the second experiment, the treatments corresponded to doses of 0, 90, 180, 360, 720, 1,440, 2,880 and 5,760 g ha-1 of glyphosate for applications in post-emergence in soybean RR. The applications took place when the castor bean plant had four to six true leaves. The evaluations done ...

Para tanto, realizamos pesquisa documental e bibliográfica e nos apoiamos em autores que pesquisam a temática. No período delimitado são apresentados dois importantes documentos para o atendimento à criança e ao adolescente no Brasil, quais sejam: o Código de Menores de 1927 e o Código de Menores de 1979, legislações em que nos focamos neste artigo. Pudemos apreender, por meio dos estudos realizados, que o atendimento, as práticas e as concepções de repressão e segregação, relativas à infância e à adolescência pobres, de modo geral, foram ocasionadas em decorrência da própria constituição da sociedade de classes. Esta constituição que demanda, principalmente às classes subalternas, um comportamento condizente com a organ...

Studies on altitudinal gradients have drawn the attention of ecologists; however, the disturbance history and geomorphologic variations in each environment should be considered. The Brazilian savanna steppe is characterized by the diversity of physiognomies, but the state of conservation of existing vegetation fragments compromising the structure of communities. The objective of this study was to test the hypothesis that the number of species of the shrub-tree component of these dry forests increases along an elevational gradient. A total of 75 sampling units were established along three altitudinal levels: 400, 500 and 600 m a.s.l. Species richness pattern was evaluated using the randomization test in the ESTIMATES 8.2 program, with the construction of cumulative curves and non-parametric estimates. Comparison between the cumulative curves, their respective confidence intervals and non-parametric estimates showed an increment of richness along the elevational gradient. Considering the composition and abundance of species, besides human activities in such environments, we can infer that the greater anthropic pressure in lower altitude ranges and the microhabitats at the higher elevations act synergistically in the determination of richness pattern in dry tropical forests.

Information was obtained through the use of semi-structured interviews with 50 people who use zootherapeutic products. A total of 25 animal species used for medicinal purposes were identified (18 vertebrates and seven invertebrates) distributed among five taxonomic categories; the groups with the largest numbers of citations were: mammals (8 citations), insects (7), and reptiles (5). The most cited animal species were: Tubinambis merianae “teju” lizards (44 citations); Apis mellifera Italian honeybees (318 citations); Gallus gallus chickens (31 citations); Ovis aries sheep (31 citations); Crotalus durissus rattlesnakes (14 citations); Boa constrictor (12 citations); and Bos taurus cattle (12 citations). A significant number of illnesses and conditions treated with animal-based medicines were cited,...

The essential components of these networks are nodes and connectors. Decomposition, topology, and properties calculated for analyzing the strategies of crown airspace acquisition in any environment. The networks represented in a two-dimensional space follow the general laws of network theory, but with specific meanings for the crown architecture. Thus, a dataset generated and included information about five individuals from fifteen tree species growing under the natural conditions of the Cerrado vegetation. We presented the types and the total number of nodes. Initial node (IN) was the node that starts the network, regular node (RN) was the vast majority of nodes with three connectors. Emission node (EN) showed four connectors, and the final node (FN) was the last in leafy axes. There are data about the distances between the initial and final nodes (IN-IF), and i...

Gagnon & G.P.Lewis (Leguminosae - Caesalpinoideae) growing under natural conditions in Caatinga vegetation area. The data are useful in plant ecophysiology, plant functional ecology by researchers investigating the woody crown traits. We obtained the data directly from a skeletonized representation of the woody crown in a two-dimensional space by hand drawing. Subsequently, the nodes counted, and their proportions (decomposition), the distances between the different types of nodes (topology), and the values of network properties (the combination of decomposition and topology) were obtained.

The present study aimed to identify plants species used in rituals of prayers and blessers evaluating the importance value (IVs) of them. Thus, there was 22 free interviews, by means of the application of questionnaires, the prayers/blessers (local experts), with the purpose also to study the knowledge and the perception of these relative local experts to the use of plants in its rituals of cure, common practical in communities that inhabit in cities of the state of the Paraiba. One searched to still understand the origin of knowledge of the prayers. The gotten preliminary results evidence that the prayers make use of plants in its practical of pray and blesses, giving them powers to remove “badly looked at” or “quebrantos”, several pains, “stickleback fallen”, among others evils. The informants had cited 15 species from 12 botanical families, with prominence fo...
