title: Breaking the misconception of a dry and lifeless semiarid region: the diversity and distribution of aquatic flora in wetlands of the Brazilian Northeast

description: ABSTRACT The semiarid region of northeastern Brazil possesses a set of wetlands characterized by hydrographic basins with deficient drainage networks, a few large and permanent lotic systems and several permanent and temporary lagoons. Aquatic plants are widely distributed in these wetlands and the present study aims to determine if those of Ceará state have similar species compositions and differences in species richness. We hypothesized that lentic ecosystems would have more species and different growth forms of aquatic angiosperms than lotic ecosystems. A total of 1619 records of aquatic angiosperms in 43 wetland areas were analysed. The most representative families were Cyperaceae, Poaceae, Fabaceae, Alismataceae, Malvaceae, Nymphaeaceae and Pontederiaceae. Most of the species are helophytes and bottom-rooted emergent hydrophytes. Permanent lentic ecosystems had the highest number of exclusive species (27.85 %), followed by temporary lentic ecosystems (20.54 %). Contrary to our hypothesis, the different aquatic ecosystems were found to possess distinct species compositions and different proportions of growth forms, and all wetland types contributed to the macrophyte richness of the study area, although they differ in species richness. Therefore, conservation plans for the native aquatic macrophyte biota should include all wetland ecosystems in the semiarid state of Ceará.

title: Enzymatic efficiency of the decomposing microbiota: what does really matter for aquatic macrophytes invasions?

description: ABSTRACT Biological invasions have negative impacts on different ecosystem-level functions, such as nutrient cycling. In aquatic environments, exotic litter can change the activity of the decomposer microbiota. We tested whether litter quality, litter decay, and enzyme activity differed between nativeEgeria densaand exoticHydrilla verticillata. The invasive plant presented higher lignin and lower cellulose content than the native plant. Both species showed rapid fibre decay in the first five days.E. densahad higher cellulose and hemicellulose decay thanH. verticillatta. Although the species did not exhibit differences in enzyme activity over time,E. densahad a higher enzymatic efficiency thanH. verticillata. This differential enzymatic performance can cause changes in the mineralisation processes of the invaded environments. The lower decomposition rates for invasive litter, associated with differences in litter quality, could increase the amount of particulate organic material in invaded environments.

title: In vitro germination of Abricó-de-Macaco (Couroupita guianensis aubl.)zygotic embryos in different culture media and light spectra

description: ABSTRACT: Couroupita guianensis Aubl. is an Amazonian forest species with important medicinal and ornamental value. This study evaluated the effect of different culture media and light spectra on the in vitro germination and development of the zygotic embryos of C. guianensis. The culture media, MS and WPM, were evaluated without the addition of plant growth regulators and were associated with four LED light spectra: white (CW), 70% red + 30% blue (R2B), 100% red (R), and 100% blue (B). One hundred percent of the seeds successfully underwent in vitro germination, and the culture media did not interfere with embryo development. In addition to this, the different light spectra induced in vitro morphogenesis and R2B treatment significantly promoted the production of secondary roots. This effect may aid in the rooting and acclimatization of seedlings of this species.

title: Macrophyte functional composition is stable across a strong environmental gradient of a Neotropical floodplain

description: ABSTRACT Ecological communities are compared by the similarity or distinctness of their species. Taking into account community composition at a determined site, one could expect a similar reasoning to explain differences in both taxonomic and functional composition due to environmental gradients. We aim to evaluate spatial variation in functional composition of aquatic macrophyte assemblages in a Neotropical floodplain. The studied floodplain is characterized by encompassing different ecoregions considering both differences in environmental features and macrophyte taxonomic composition. Therefore, we hypothesized that macrophyte functional composition would differ among ecoregions but instead found limited differences in functional composition. There was only a little evidence that some life forms are more or less observed in certain ecoregions. Thus, the considerable environmental heterogeneity found at the ecoregion scale is reflected only in taxonomic, and not in functional composition. This result can be explained by different species having high functional redundancy: different functional traits could be recorded in all ecoregions. Therefore, we suggest that the functioning of the entire ecosystem is probably insured by species functional redundancy in this Neotropical floodplain. Nonetheless, we cannot rule out the fact that trait choice could affect interpretations, and so trait selection should be better explored, particularly for aquatic macrophytes.

title: Genetic structure and diversity in Neochen jubata (Aves: Anatidae) from the Araguaia River, GO, Brazil

description: Abstract: The Orinoco Goose (Neochen jubata) is a few-known and endemic Anatidae to South America, inhabiting sandy beaches along medium and large rivers, with a well-developed riparian forest and in swamp savannas and large freshwater baths. Recent data indicate the presence of longitudinal migratory behavior, and despite them, there are no records on the genetic profile of this species. The Araguaia River region, in the municipality of Luiz Alves, Goiás, receives an undetermined number of ducks seasonally, and there is little information about the individuals who visit this place, constituting the ideal scenario for a study able to offer a genetic overview perspective of this species and to understand the relationship between these individuals better. For this, we genetically characterized 61 individuals sampled in three distinct years of collection using microsatellite molecular markers and mitochondrial DNA. Genetic diversity analyses revealed low levels of heterozygosity for all sampled groups. However, they are within the equilibrium proposed by Hardy-Weinberg (HWE), as inbreeding or drift are not acting in these groups. The parentage analysis supports it, showing a high number of unrelated individuals over the years. AMOVA showed a significant difference among groups. These results may reflect the structure of this migratory species in that region, with the paired differentiation test of individuals from 2013 and 2014 being more similar to each other than those from other years, indicating a possible genetic structure diagnosed by the years of capture. However, there is a high allelic sharing among the three sampled groups, suggesting that these individuals are a population that connects over time and that they have a philopatric relationship with the location. The results found in this study constitute an initial milestone for the genetic knowledge of the mallard duck that should be raised in many other genetic studies.

title: Effect of 20-OH ecdysone and methyl farnesoate on histomorphology of the Y-organ during late intermoult and postmoult stages in the freshwater crab Travancoriana schirnerae Bott, 1969 (Crustacea: Gecarcinucidae)

description: Abstract This study investigated the effects of 20-OH ecdysone (20E) and methyl farnesoate (MF) administration on histomorphology of the Y-organ (YO) during late intermoult (C3 and C4) and early postmoult stages in the edible freshwater crab Travancoriana schirnerae Bott, 1969, widely distributed in the wetlands of Wayanad, Kerala, India. Histomorphological analyses of the 20E and MF administered crabs revealed that both 20E and MF were effective in inducing significant changes in YO during the late intermoult (P &lt; 0.001) and early postmoult (P &lt; 0.05) stages, as evidenced from a significant rise in the YO index (YO index = wet weight of YO/body weight of crab × 100), size of the gland and lobules, height of the lobular epithelium, cellular hypertrophy, presence of secretory vesicles and abundance of hemocytes. The results also indicated that the effects were more pronounced during the late intermoult stages than the postmoult stage and in the 20E administered crabs than the MF administered individuals. The percent increments in YO index, length and width of the gland and lobules and thickness of the lobular epithelium in 20E and MF injected crabs during the late intermoult stages were 25.95, 20.04, 27.22, 52.15, 67.24, 114.50 % and 16.19, 9.09, 14.45, 21.87, 23.97, 65.25 %, respectively while those of early postmoult were 13.63, 24.04, 25.73, 23.86, 26.13, 38.01 % and 9.09, 15.27, 19.85, 14.95, 19.65, 26.54 %, respectively. In conclusion, 20E and MF administration provide an excellent option for stimulation of YO, thereby inducing ecdysis and growth during the inactive stages (intermoult and postmoult) of the moult cycle.

title: Readiness for interprofessional education in undergraduate courses based on active learning methods

description: Abstract: Introduction: Interprofessional Education (IPE) helps develop collaborative skills, enhance patient safety and improve the quality of health care. Readiness for shared learning is directly related to IPE. Objective: To analyze Readiness for IPE among students, according to the cycles and courses. Method: This cross-sectional, descriptive study adopted a quantitative approach and used the Readiness for Interprofessional Learning Scale (RIPLS) via an electronic form. Mann-Whitney and chi-square tests were used to analyze the continuous and categorical variables, respectively. Analyses to ascertain differences between scores for the factors (1) Teamwork and Collaboration (TEC), (2) Professional Identity (IP), (3) Patient-Centered Health Care (ACP), and the overall RIPLS score, used the Kruskal-Wallis test to compare courses and cycles. Result: A response rate of 32.6% was attained from a sample of 506 students from the Nursing, Pharmacy, Physiotherapy, Speech Therapy, Medicine, Nutrition, Dentistry and Occupational Therapy courses of a Brazilian public university. The scores for factors 1, 2 and 3, and the overall RIPLS score did not differ between genders. Pharmacy students reported a lower Readiness for factor 3 (ACP) compared to students in Nursing, Physiotherapy, Medicine, Dentistry and Occupational Therapy (p=0.007). Speech therapy and Nutrition reported lower scores for the same factor compared to Dentistry and Occupational Therapy (p=0.007). Pharmacy students (p=0.004) and medicine students (p=0.016) were less likely to obtain a higher score in factor 1(TEC), while Occupational Therapy students were more likely to report greater Readiness in the same factor (p=0.024). In factor 2 (IP), fifth grade students were less likely to have positive attitudes (p=0.046). It was observed that Occupational Therapy students showed a more favorable attitude towards IPE expressed both in factor 3 (p=0.034) and in the overall score (p=0.027), while students in the Pharmacy course were less likely to report better readiness in factor 3 (p=0.003) and in the overall score (p=0.003). Conclusion: Considering the relevance of IPE in the process of redirecting health care training to build comprehensive care and ensure alignment with the Unified Health System, this study aims to reflect on the differences in readiness for IPE between undergraduate courses in health area.
