title: Colonization-related functional traits of plants in a 50-hectare plot of secondary tropical forest

description: ABSTRACT The growth-survival trade-off hypothesis states that functional traits of stem, wood, leaves and fruits govern acquisitive and conservative strategies of plant species that grow/survive differently in forests. We aimed to determine whether heterogeneity during the colonization of a secondary Atlantic Forest fragment causes differences in colonization-related traits and determines taxonomic composition of subplots. A total of 5,078 subplots were censused with leaf and fruit traits and height measurements being determined for each tree of each species, and with averaged-abundance-weighted values calculated for each subplot. A dendrogram was generated from the taxonomic composition of subplots using Sorensen similarity and UPGMA clustering. A total of 74,335 trees of 178 species were recorded. Clustering revealed five main groups of subplots that were tested against each other and found to differ in terms of average leaf width, leaf-width/petiole-width, wood density, mean height, height mode, fruit width and fruit length. Greater leaf averages in subplots were associated with greater fruit averages, and with higher wood densities and greater heights among groups of subplots, revealing that heterogeneity during colonization directed the communities of the 50-ha plot. The averaged values of functional traits detected subplots associated with conditions favorable to colonization, thereby reinforcing the growth-survival trade-off hypothesis.

title: Sustainable production of bioactive alkaloids in Psychotria L. of southern Brazil: propagation and elicitation strategies

description: ABSTRACT Psychotria is the largest genus in Rubiaceae. South American species of the genus are promising sources of natural products, mostly due to bioactive monoterpene indole alkaloids they accumulate. These alkaloids can have analgesic, antimutagenic, and antioxidant activities in different experimental models, among other pharmacological properties of interest. Propagation of genotypes with relevant pharmaceutical interest is important for obtaining natural products in a sustainable and standardized fashion. Besides the clonal propagation of elite individuals, the alkaloid content of Psychotria spp. can also be increased by applying moderate stressors or stress-signaling molecules. This review explores advances in research on methods for plant propagation and elicitation techniques for obtaining bioactive alkaloids from Psychotria spp. of the South Region of Brazil.

title: PREVALENCE OF POPEYE DEFORMITY AFTER LONG HEAD BICEPS TENOTOMY AND TENODESIS

description: ABSTRACT Objective: To evaluate whether body mass index (BMI) 30 can be used as a cut-off point in decisions about whether or not to perform long head biceps (LHB) tenodesis, leading to a low rate of esthetic complaints, and to compare two tenodesis techniques. Methods: Ninety-six patients underwent shoulder arthroscopy where tenotomy was performed separately in patients with a BMI ≥30 and was followed by tenodesis when BMI &lt;30. The patients were assessed on the basis of their personal perception of the deformity and by 3 independent observers. Results: The patient's perception of esthetic deformity in the arm was 15.6%. In the tenotomy group (12.5%) and in the tenodesis group (17.9%) - (p = 0.476). Patients with rocambole-like tenodesis perceived the deformity in 13.2% of cases, while patients with anchor tenodesis noticed the deformity 27.8% (p = 0.263) of the time. There was no statistical difference in the perception of deformity among the independent examiners. Conclusion: BMI 30 can be used as a cut-off point in decisions about whether or not to perform LHB tenodesis, leading to low rates of esthetic complaint by patients (12.5%). The rocambole-like tenodesis technique appears to be more able to avoid esthetic deformity of the arm after the LHB tenotomy according to the patients' observations.

title: Analysis of grid of points influence on daylight metrics

description: Abstract The luminous performance of buildings can be evaluated using several tools, most of them based on illuminance. Although progress has been made in daylight metrics in recent decades, mainly due to developments in computer systems technology, they do not usually address how grids are defined. This paper analyses the influence of the grid influence on the performance of the following metrics: average illuminance (Em), uniformity (U), daylight autonomy (DA), continuous daylight autonomy (cDA), spatial daylight autonomy (sDA), useful daylight illuminance (UDI) and annual solar exposure (ASE). Daylight simulations were done using TropLux, in a 6x6 m2 room without shading device. Exploratory and statistical analyses were performed using the ANOVA method, Tukey tests and a correlation matrix. The results indicate that the grid of points influences on the precision of the studied metrics. For Em, U, DA, cDA, sDA and UDI, the results stabilised starting from a 6x6 grid with a 1,00m distance between points. For ASE, a grid with 11x11 points, or a 0.54 m distance between points was required. This study suggests that a different analysis of skylight and direct sunlight, taking into account grid size, may optimise computer performance maintaining accuracy.

title: Catalogue of the vascular epiphytic flora of Uruguay

description: ABSTRACT We provide an updated list of the vascular epiphytic flora occurring in native environments of Uruguay based on literature review, herbarium specimens, and fieldwork throughout the country. The catalogue provides standardized information for each species, including accepted name, synonyms used within Uruguay, epiphytic category, distribution within the country, habitat, conservation status, observations, and a voucher citation. The effort documented 73 species for the epiphytic flora of Uruguay (3 % of the flora), distributed among 29 genera and 12 families. Bromeliaceae was the richest family (17), followed by Polypodiaceae (16) and Orchidaceae (12). Tillandsia stood out as the most speciose genus with 15 species. Characteristic holoepiphytes was the most diverse ecological category. More than half of the epiphytic species documented for Uruguay (53 %) reach their southernmost geographic distribution in the country, whereas only two mostly epipetric species of Tillandsia - T. arequitae and T. uruguayensis - are endemic to the country. Almost half of the epiphytic species found are presently under categories of threat of extinction, with 60 % of them occurring in national protected areas. Both the richest epiphytic families and the predominance of characteristic holoepiphytes coincide with findings from floristic and ecological studies previously carried out in humid subtropical regions.

title: Enhanced removal of emerging micropollutants by applying microaeration to an anaerobic reactor

description: ABSTRACT The present paper aimed to evaluate the impact of microaeration on both the removal performance of some emerging micropollutants (pharmaceuticals, hormones, and bisphenol A) and the microbial community structure of an anaerobic reactor treating synthetic wastewater. Under anaerobic conditions, the removal efficiencies of the micropollutants were very low (&lt; 10%). However, the microaeration (1.0 mL air·min-1 at 27 °C and 1 atm, equivalent to a QAIR/QINF ratio of 0.1) expressively improved the removal efficiencies of all compounds (&gt; 50%). Therefore, supplementing anaerobic reactors with low amounts of oxygen seems to be an interesting strategy to enhance the removal of the micropollutants tested. However, further studies should be carried out with other compounds in order to evaluate the wide applicability of microaeration to different classes of micropollutants in lab- and full-scale treatment systems. Concerning the microbiota structure, both bacterial and archaeal communities were not compromised by the different operational conditions and preserved their functional organization with high richness during the whole experiment.

title: Effectiveness of a low-dose Norgestomet ear implant in short-term protocols to induce estrus in ewes during the non-breeding season in Brazil.

description: ABSTRACT The objective of this study was to evaluate the reproductive performance of ewes subjected to a short-term protocol for estrus induction using 1 mg of Norgestomet during the non-breeding season in Brazil. A total of 84 ewes were randomly divided into two equal groups (n = 42 per group). Controlled Internal Drug Release (CIDR) containing 330 mg progesterone was inserted into the vagina in the first 42 ewes, and for the other 42 ewes in the second group, 1 mg of Norgestomet was placed subcutaneously in the convex surface of the ear. Implants and devices were removed in both groups on day 6. Following the removal of implants and devices, 10 mg of PGF2α and 300 IU of eCG were injected in all the ewes. After 48 h of application, three fertile rams were added to the herd. Ewes and rams were kept together for four days. Rams were removed on day 12, and after 42 days, pregnancy was diagnosed by ultrasound scanning. Short-term protocols using either an intravaginal device or ear implant were similarly effective to estrus induction (95.23 vs. 92.85%), and all ewes from both groups had estrus manifestation within 72 h after implant removal (72±9 h). In addition, no significant difference in pregnancy rate was observed between ewes treated with the intravaginal device and ear implant protocols (52.38 vs. 57.14%). These results suggest that 1 mg of Norgestomet is a good alternative for short-term protocols for estrus induction/synchronization during the non-breeding season in ewes. It is possible to replace the progesterone-releasing intravaginal device by the ear implant and obtain the same reproductive effectiveness in ewes.

title: Species boundary and extensive hybridization and introgression in Petunia

description: ABSTRACT Studying the role of hybridization in the speciation of plants is one of the most thrilling areas of evolutionary biology. Hybridization in natural populations can act in opposition to divergence, contribute to adaptation through introgression or foster the emergence of new lineages via hybrid speciation. Species of the plant genus Petunia grow in open areas in southern South America. Some natural interspecific hybrid events have been described for the genus, such as between the endemic P. exserta and the widespread P. axillaris. Both species occur in sympatry in Serra do Sudeste (Brazil), where they occur in diverse habitats and exhibit floral divergence, which has been related to the attraction of different primary pollinators. The present study evaluates the maintenance of the species boundaries front of hybridization and introgression. Direct and indirect methods of estimating gene exchange employed genotyping 720 reproductive plants and 611 progenies of both species with eight microsatellite loci. Gene exchange was found to be frequent and bidirectional between the species, indicating that introgression changes their genetic constitution in areas of sympatry. Limits of the studied species are being maintained because of the high level of inbreeding and backcrosses that are habitat-dependent.

title: QUALITY OF LIFE IN PATIENTS WHO HAVE UNDERGONE REVERSE SHOULDER ARTHROPLASTY

description: ABSTRACT Objective: To evaluate the health-related quality of life (HRQoL) of patients who have undergone reverse shoulder arthroplasty (RSA) for rotator cuff arthropathy (RCA). Methods: A retrospective study with 35 patients who underwent RSA from August 2007 to July 2015. We collected clinical data and applied the 36-item Short Form Health Survey (SF-36). Results: Of the 35 patients, 29 (82.9%) were female, and mean age was 75.71 years, ranging from 50 to 89 years. The dominant side was frequently affected (68.6%), and most of the cases were Hamada type 3 (57.1%). The Mackenzie approach was used in 30 patients (85.7%). Physical and mental HRQoL was not associated with severity of RCA before RSA. Lower scores for Physical Functioning, Role Physical, Bodily Pain, and Physical Component Summary (PCS) were associated with other orthopedic comorbidities. Vitality, Role Emotional, Mental Health, and Mental Component Summary (MCS) were significantly higher in patients without depression. Orthopedic comorbidity and depression predicted lower PCS and longer follow-up time predicted better PCS scores. Depression was also a predictor of the MCS. Conclusion: Patients who had undergone RSA for RCA had good HRQoL. Longer follow-up time was associated with better HRQoL. Good results were maintained over the follow-up period. Level of evidence II, retrospective study.

title: Genetic diversity in Calibrachoa pygmaea (Solanaceae): A hawkmoth-pollinated nightshade from the Pampas

description: ABSTRACT Calibrachoa pygmaea is a unique species of Calibrachoa, especially concerning its flower morphology and the environment where it occurs. The species is self-incompatible and is narrowly distributed in wet and flooded fields of the Pampas region. We characterize the genetic diversity of the species based on traditional plastid markers and newly developed nuclear microsatellites to identify drivers that guide its evolution. Our results identified markers that are informative and useful for studying the population structure of C. pygmaea, as well as that of other species of Calibrachoa. Both marker sets were congruent in developing conclusions regarding the evolutionary scenario of C. pygmaea, and revealed that the genetic variability and population structure of the species could be explained by common allele fixation or shared ancestral polymorphism, while its diversification can be attributed mainly to the species’ dispersal ability and certain ecological features.

title: Ornamental fishing in the region of Barcelos, Amazonas: socioeconomic description and scenario of activity in the view of “piabeiros”

description: Abstract The Negro river basin is considered the largest area of extractive of ornamental fish in Brazil. This area has fundamental importance for the populations from the Amazon. The present study aimed to describe socioeconomic profile of ornamental fishermen known as “piabeiros” in the Municipality of Barcelos, as well as the ornamental fishery, fisheries area, target species, environments, fishing techniques, equipment, capture techniques and main difficulties faced by the current activity. This study was carried out in municipality of Barcelos, through semi - structured interviews, with artisanal ornamental fishermen (N= 89). The main families of ornamental fish caught and traded were: Characidae, Lebiasinidae, Gasteropelecidae, Cichilidae, Anostomidae, Loricaridae, Potamotrygonidae and Gymnotidae. The main catchment areas were igarapés, lakes, flooded fields, beaches, river banks and igapó forest. Rapiché was the most used equipment in the fisheries both by the fishermen of the urban areas (43.81%) and rural (41.89%). Most of the fishermen are associated with the colony of fishermen of Barcelos (Z33). The data showed that the dynamics of ornamental fishing have changed in a short time and directly affected fishermen, in addition to the low age renewal with the participation of younger fishermen, threatening the transmission of ecological knowledge to future generations. As a result, the increase of the problems related to the productive chain and absence of public power to the activity, since ornamental fishing has already been treated as one of the main economic activities more important for the local communities and for the State of Amazonas.
