title: Tree species used by fishermen for building handmade rafts, Environmental Protection Area of Costa Itacaré-Serra Grande, Bahia, Brazil

description: The "jangadeiros" are populations of artisanal fishermen of coastlines living in the northeastern Brazilian coast. Currently, it appears that only in some regions such as the southern coast of Bahia, the living culture of fishing with handmade rafts still persists. The present study aimed to survey tree species used for building handmade rafts in southern Bahia, investigating the possible sources of this knowledge kept by artisanal fishermen. The survey was conducted in the district of Serra Grande, Uruçuca, Bahia, between April and May 2013, through 13 semi-structured interviews. The results were analyzed qualitatively. A total of 13 species were cited. The most cited species are Apeiba tibourbou (Malvaceae) and Albizia polycephala (Fabaceae). The continuity of knowledge of artisanal fishing has been compromised due to the difficulty in extracting the raw material. A new component was introduced in traditional rafts, the engine, between four and seven years ago. The results of this study demonstrate the importance of the relationship of the community and the environment in which they live and the species used in the making of rafts, keeping alive a culture that disappeared in other regions. However, urgent actions are needed so that the culture does not disappear due to changes in habits and legal and logistical difficulties in obtaining raw materials.

title: Tree species of Papilionoideae (Leguminosae) in northwest of São Paulo state, Brazil

description: In this study, we collected woody plants of Papilionoideae, Leguminosae, in the northwest region of São Paulo state, southeastern Brazil. The study area has one of the most fragmented vegetation within the context of the region, and it is still poorly known about the flora. Nineteen species were recorded in eleven genera and three tribes. The most representative tribes were Sophoreae, with the genus Bowdichia, Leptolobium, Myroxylon, Sweetia and Ormosia; tribe Dalbergieae, with Andira, Centrolobium, Machaerium and Platypodium, and tribe Dipterygeae represented by Dipteryx and Pterodon. Machaerium presented the highest number of species, with eight, followed by Leptolobium, with two species. The other genera were represented by one species each. The species distribution data showed that the regional flora consists of species with wide distribution in the Cerrado, in central Brazil, and species that occur primarily in the Atlantic forest in eastern Brazil. Keys, descriptions and illustrations of the taxa found are displayed.

title: Floral traits as potential indicators of pollination vs. theft

description: Abstract Floral visitation does not necessarily mean pollination, as several animals utilize floral resources without transferring pollen. Since pollinators and thieves can affect the reproduction, morphology and diversification of flowering plants, we here investigated if attributes of flowers and flowering of plant species collected in the central Brazilian vereda would predict the pollination (pollen seeking) or theft (pollen/nectar theft) during the visits. It was hypothesized that non specialized flowers would have a higher incidence of thievery, where as specialization, for example, the presence of large and medium flowers with long corolla, making it difficult to access nectar, would lead to increased pollination. As a result, four attributes were mainly associated with illegitimate visits, and in order of importance, they are size (small), quantity of flowers per plant (large), flowering time (&lt; 10 months) and floral type (inconspicuous). The richest and most abundant visitor groups, including bees, flies and wasps, acted mainly as potential pollinators, while cockroaches, butterflies, beetles, ants and hemipterans acted as thieves. However, further studies are required to confirm that this pattern is repeated in other larger and more diverse communities, thus confirming the possible preference for floral thieves.

title: Functional diversity of reproductive traits increases across succession in the Atlantic forest

description: Abstract Niche and neutral processes shape community assembly with a possible shift of niche and neutral importance in communities undergoing temporal changes during succession. Functional diversity helps to discriminate assembly processes since trait distribution is dependent on those processes. We evaluated the changes in reproductive traits related to pollination and seed dispersal in a successional gradient in an Atlantic Forest area, Southern Brazil. We surveyed forests undergoing regeneration varying in age from 2 to 80 years after pasture abandonment. We expected an increase in functional diversity of reproductive traits and a greater role of limiting similarity across succession. Abiotic and mixed pollination systems, dioecious sexual system, biotic dispersed, many-seeded and small-seeded species decreased as the forest got older. Conversely, bee-pollinated, bell-shaped, small and androgynous flowers increased across forest succession as well biotic dispersed and large-seeded species. Functional richness and functional dispersion were higher in older forests. Changes in functional diversity were positively related to species richness, indicating that species enrichment in older forests added new sets of reproductive traits. These changes in trait distribution and functional diversity across succession in the Atlantic Forest suggest an increased role of biotic interactions and limiting similarity process structuring plant assemblages of second-growth tropical forests.

title: Are the wing's cells alive? Study case in Vriesea trichomes

description: Abstract The presence of peltate foliar trichomes is one of the main anatomical characteristic of Bromeliaceae. These complex structures are adapted to compensate water and nutrient absorption in species that have reduced or substrate and light-reflection independent roots. They have enabled species' survival in diverse and extreme environments contributing to the wide distribution of this family. In the present work, we analyzed the peltate trichomes' characteristics in three taxa of Vriesea (Tillandsioideae): Vriesea platynema var. platynema, V. platynema var. variegata and V. tijucana. Leaves in different developmental stages were analyzed with histochemical tests and Transmission Electron Microscopy. Main results include the presence of cytoplasmic content in the wing peripheral cells, as well as in mature leaves. This is the first register of the presence of such feature in this family, which brings the possibility of discussing how water can be absorbed by these cells.

title: Vascular epiphytes on Pseudobombax (Malvaceae) in rocky outcrops (inselbergs) in Brazilian Atlantic Rainforest: basis for conservation of a threatened ecosystem

description: Abstract This study evaluated the richness of vascular epiphytes on Pseudobombax sp. nov. in three inselbergs in the Atlantic Forest Domain in state of Espírito Santo and evaluated the floristic similarity between the areas. We sampled 111 phorophytes in three regions in the southern of Espírito Santo state and identified 151 species, 77 genera and 21 families of vascular epiphytes, of which the families Orchidaceae and Bromeliaceae showed the highest richness. Non-parametric estimators (Chao 2, Jackknife 1) indicate that 90 and 95% of species richness of epiphytes was recorded. The most diversified ecological category was the characteristic holoepiphytes. The ratio of the number of epiphytes and number of phorophytes sampled in a montane inselberg, in this study, was greater than the richness of vascular epiphytes found in the rocky outcrops of quartzite, and, in general, different types of Atlantic Domain forests, but smaller in richness for some Dense Ombrophilous Forests of southern Brazil. The three inselberg areas had distinct floras. The high richness, the endemism found, and the number of endangered species of epiphytes demonstrate the important role of Pseudobombax sp. nov., because of its architecture and size, in the maintenance of biodiversity on the inselbergs in southeastern Brazil.

title: Differences between root and stem wood in seedlings and sprouts of Sessea brasiliensis (Solanaceae)

description: Abstract Young Sessea brasiliensis trees derived from seeds and sprouts after coppicing were analyzed for differences in axial variation of anatomical features. It was hypothesized that 1) quantitative variation in anatomical features in the axial direction would indicate adjustments in water conductivity and mechanical strength along tree height and 2) significant quantitative differences in anatomical features would be observed between trees originating from seed compared to those derived from sprouts after coppicing. Results showed that wood originating from sprouts after coppicing developed differently from wood originating from seeds. Specifically, for seed provenance samples, narrower vessels were observed in the transition zone, whereas for sprouting provenance, narrower vessels were seen in roots and trunk base. Also, when comparing axial variation between seeds and sprouts, vessel diameter was smaller in plants of seed origin in the transition zone, whereas fiber diameter was smaller in trunk top and branch in plants of seed and sprouting provenances, respectively. Higher rays were observed in branch and trunk top when comparing different axial position in both origins. Thus, the first hypothesis is confirmed by significant axial variation in vessels, fibers and rays, and the second hypothesis is confirmed by the significant differences observed between trees of seed and sprout origins.
