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 ...

This study was conducted in two areas of the Caatinga with altitudinal gradients (in a mountain range), in the microregion of the Cariri Oriental Paraibano. It had the goal of characterizing the stages of ecological succession of the plant communities based on the classification of species into ecological groups and comparatively analyzed the phytosociological structure of the two areas, which are influenced by different levels of anthropization. The tree-shrub flora (with diameter ≥ 3 cm and height ≥ 1 m) of the Serra Inácio Pereira was represented by 1043 individuals, 17 families and 42 species and in Serra do Monte by 1264 individuals, 13 families and 29 species. The Shannon diversity index was 2.790 and 2.313 nats.individual-1 , respectively. Area I (Serra Inácio Pereira) had a higher diversity of families and species compared to Area II (Serra do Monte); the latter being more influenced by the process of anthropization. In Area I, the species of greatest ecological importance were Myracrodruon urundeuva Allem. and Sapium sp. In Area II, Caesalpinia pyramidalis Tul., Aspidosperma pyrifolium Mart. and Croton sonderianus Muell. Arg. were the species with the highest importance values (IV). Area I appeared to be in an intermediate stage of succession, where the pioneer species were dominant over the early secondary species, along with late secondary species with high IV. In Area II, 70% of the individuals were pioneer species, characterizing the vegetation as being in the process of regeneration. Area I had heterogeneous vegetation, exhibiting a healthy state of conservation. However, Area II appeared to be homogeneous, demonstrating that the level of disturbance accounted for the differences between the two areas in floristic composition, structural formation and, as a consequence, stage of ecological succession.

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.

Such fact suggests that conservation strategies for snakes should consider the interactions and perceptions of the local population towards these animals. The aim of this study was to investigate students' perception of snakes and if attitudes and knowledge may differ according to gender and local residence (urban or rural). Methods: Data was collected in the second half of 2012 and consisted of questionnaires applied to 108 students in the Basic Education School in the municipality of Sumé, located in the semiarid region of Northeastern Brazil. Results: The male respondents recognized more species than female did. Part of the students affirmed to have a fear of snakes, especially women. Nearly half of respondents (49%) showed negative behaviour towards these animals, reflecting the influence of potential risk and myths associated with snakes, and supported by a limited knowledge about these animals and their ecological and utilitarian role. We find that the rural students recognized significantly more species than the urban students. Conclusions: Our results point to the need for educational interventions in order to increase knowledge about the positive aspects associated with snakes, seeking to minimize the influence of myths and beliefs that contribute to a strong aversion to snakes by the locals. Conservation strategies should therefore engage students but also teachers, who are key individuals in the process.

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...
