title: Coexistence of endemic peacock basses (Cichla) in a Neotropical reservoir (Cichlidae: Cichliformes)

description: Abstract Peacock basses (genus Cichla) are predatory fish widely distributed across the Amazon, where two or more species normally coexist in a same drainage. The mechanisms that allow coexistence remain poorly understood, although these species share a number of functional traits and behavioral aspects. To advance on this question, the present study compared population and functional traits of Cichla kelberi and C. piquiti, based on data collected between 2010 and 2020 in the upper section of the Lajeado Reservoir, Tocantins River. Both species were captured in all sampling sites, frequently in a same sample, but C. piquiti was far more frequent and abundant. The species used the same habitats, and co-occurred more often than expected by chance. Species had a similar diet (small-sized fish), reproductive effort, fecundity and fat accumulation, but C. piquiti showed larger body sizes, shoaling behavior, a longer reproductive period, and morphology associated with greater swimming potential. Overall, results revealed that these species coexist in the impoundment, with significant overlap in the use of habitats and food resources. Differences in other functional traits may favor their coexistence, possibly involving niche partitioning, which seem to explain the dominance of C. piquiti in the impoundment.

title: Post-fire effects on bryophytes in High-Altitude Fields

description: ABSTRACT High-Altitude Fields are ecosystems with high bryophyte abundances and diversities. One of the principal threats to these ecosystems are wildfires, which mainly affect terricolous species. Chronosequence studies can aid in understanding post-fire effects on bryophytes. We studied terricolous assemblages of bryophytes in the High-Altitude Fields of Itatiaia National Park (INP) by establishing three 20x1 m transects in five areas: three areas of a post-fire chronosequence (treatments 2017, 2007, and 2001) and two control areas. We analyzed the species richness, floristic composition, life-forms, and floristic similarities of those transects, identifying 27 species of mosses (18 genera; 11 families) and 26 species of liverworts (20 genera; 16 families). Ditrichaceae was the principal moss family and Cephaloziellaceae the principal liverwort family. The life-forms encountered were turf (43 %), weft (38 %), thalloid (10 %), and mat (9 %). Turf predominated among mosses (85 %), and weft among liverworts (62 %). Species richness and floristic compositions varied among the post-fire gradients. The grouping dendrogram and ordination diagram evidenced greater similarity among transects within the same area. However, there was no evident gradient of floristic composition along the post-fire gradient, and further studies will be needed to quantify environmental gradients and their influences on bryophyte composition.

title: Study on the state of the art of critical success factors and project management performance

description: abstract: This article has carried out a state-of-the-art survey of the main international publications related to Critical Success Factors (CSFs) and project management performance from 2009 to 2019. The publications were extracted from the databases of the platforms Engineering Village, Web of Science and Scopus. In total, 77 works published in major international journals were selected for the bibliographic review. It was noted that the approaches that stood out in these articles are related to evaluation system, maturity analysis, types of strategies, use of management tools, and project governance process. The research has also identified 19 CSFs most cited in these publications and grouped them into categories. The results showed that a CSF related to human resources – team commitment – was the most cited in the publications. It is expected that the results of this work can contribute to the understanding, expansion and continuous enhancement of research in the field of project management. By producing a database of scientific works and presenting an overview of the needs and challenges that have to be overcome, it should also contribute to providing researchers with a theoretical background for further development in the field.

title: Evaluation of in vitro experimental model for analysis of bioceramic sealers

description: Abstract This study aimed to evaluate physicochemical properties of three ready-to-use calcium silicate-based endodontic sealers: Endosequence BC Sealer, Bio C Sealer, and Sealer Plus BC. Radiopacity was evaluated using specimens of 10 mm in diameter and 1 mm in height, along with an aluminum step wedge. For the flow test, 0.5 mL of each sealer was deposited between glass plates and the mean of the measurement of two diameters was considered the cement flow value. For pH and calcium release, root canals of 30 prototypes of upper incisor acrylic resin teeth were filled with sealer and gutta percha point and then immersed in containers with 13 mL of ultrapure water. Both pH and release of calcium ions (atomic absorption spectrophotometer) were measured at 3, 24, 72, and 168 h. Acrylic resin teeth were scanned by Micro-CT 1174 at the time of pH and calcium ion readings for volumetric change analysis. The data were analyzed by ANOVA, Tukey’s, Kruskal-Wallis, and Dunn’s tests. Endosequence BC Sealer presented the lowest, and Bio C Sealer the highest volumetric change after 72 h and 168 h (p &lt; 0.05). Endosequence BC Sealer presented higher radiopacity (p &lt; 0.05). All materials showed alkalinization capacity. All of them presented calcium ion release, with a higher value for Sealer Plus BC. All materials presented alkalinization, calcium release capacity, radiopacity, and flow above the minimum values required by the ISO standard. The highest volumetric loss was experienced by Bio C Sealer and the lowest one by Endosequence BC Sealer.

title: Rhetorics of climate action from the South: analysis of the discourses of COP25 decision makers

description: Abstract The Conferences of the Parties function as transnational platforms to plan and implement mechanisms for climate action. The objective of this article is to analyze the discourses of the Global South in the context of COP 25, to unveil the environmental rhetoric of decision makers. For this, thematic content analysis was carried out on 60 statements of the high segment of COP25. It was possible to identify three rhetorics about climate action: urgent; ethical; cooperative, and two rhetorics about the climate regime from the South: the historical responsibility of the North and vulnerability as a condition that hinders climate action from the South. It is concluded that within the parties' discourses, a hegemonic rhetoric of climate inaction prevails, one which is focused on decision makers, is unable to implicate other actors, and reproduces the current logic of the climate regime.

title: Synthesis of Eugenol-Fluorinated Triazole Derivatives and Evaluation of Their Fungicidal Activity

description: Eugenol (C10H12O2, 4-allyl-2-methoxyphenol) is a phenolic natural product that has several biological activities and possibilities of applications. It is herein described the synthesis of eugenol-fluorinated triazole derivatives and evaluation of their fungicidal activity. The reaction of eugenol with epichlorohydrin resulted in the preparation of (±)-2-((4-allyl-2-methoxyphenoxy)methyl)oxirane (1) in 88% yield. The azidolysis of 1 with sodium azide gave the azido-alcohol (±)-1-(4-allyl-2-methoxyphenoxy)-3-azidopropan-2-ol (2) in 94% yield. The CuAAc reaction between compound 2 and different terminal alkynes afforded a series of eleven derivatives (3a 3k) within 48-80% yield. All the synthesized compounds were characterized by infrared (IR) and nuclear magnetic resonance (1H and 13C) spectroscopies and high-resolution mass spectrometry. The in vitro inhibitory activity of the compounds on the mycelial growth of a strain of Colletotrichum sp., that causes anthracnose disease on papaya fruits, was evaluated. The best result was observed for compound 1-(4-allyl-2-methoxyphenoxy)-3-(4-(2-fluorophenyl)-1H-1,2,3-triazol-1-yl)propan-2-ol (3d) that showed a mean growth-inhibition zone of 5.10 mm in a well-diffusion assay, and may serve as a template for additional structural modifications, aiming for more potent fungicidal activity.

title: Dataset of ApkDiffer

description: We evaluate ApkDiffer on 50 Andorid app from F-Droid, we randomly select 50 apps from the F-Droid repository. For each app, we download the source code of three released app versions (i.e., Vα, Vβ, Vγ), with constant version gap between them (i.e., Vβ=Vα+1, Vγ=Vα+5). With these app versions in hand, we construct two benchmark datasets for method alignment: Dataset∆1 contains true method mappings between Vα and Vβ of all 50 apps. Dataset∆5 contains true method mappings between Vα and Vγ of all 50 apps. Dataset∆1 contains true method mappings between Vα and Vβ of all 50 apps,Dataset∆5 contains true method mappings between Vα and Vγ of all 50 apps. The folder of each app contains three different versions of apk files, three mapping.txt files for restoring information before obfuscation, and two gt files containing true method mapping.

title: Uncertainties and risks in delimiting species of Cambeva (Siluriformes: Trichomycteridae) with single-locus methods and geographically restricted data

description: Abstract Cambeva contains species with complex taxonomy or poorly delimitated in terms of morphology and geopraphic distribution. We conducted an extensive review of Cambeva populations from coastal drainages of Southern to Southeastern Brazil to evaluate species geographic limits with an integrative analysis including morphological and molecular data (COI). We test if two single-locus methods, Bayesian Poisson Tree Processes (bPTP) and Generalized Mixed Yule Coalescent (GMYC), are efficient to delimit species boundaries in Cambeva by the comparison with the diagnosable morphological units. Using GMYC, we also evaluated the combination of tree and molecular clock priors to reconstruct the input phylogeny and assessed how well the implemented model fitted our empirical data. Eleven species were identified using a morphological diagnosability criterion: Cambeva balios, C. barbosae, C. botuvera, C. cubataonis, C. davisi, C. guaraquessaba, C. iheringi, C. tupinamba, and C. zonata and two treated as undescribed species. In contrast with previous knowledge, many of them have wider distribution and high intraspecific variation. Species delimitation based on single-locus demonstrated incongruences between the methods and strongly differed from the morphological delimitation. These disagreements and the violation of the GMYC model suggest that a single-locus data is insufficient to delimit Cambeva species and the failure may be attributable to events of mitochondrial introgression and incomplete lineage sorting.
