title: Influence of environmental variables on the diatom communities of oligotrophic reservoirs for public water supply (Guarulhos, Southeast Brazil)

description: Abstract Aim: Our study aimed at analyzing the diatom community structure of the plankton, periphyton, and surface sediments, and their relationship with the environmental variables of two reservoirs, Tanque Grande and Cabuçu, located in the city of Guarulhos, Metropolitan Region of São Paulo. Methods Three sampling stations were stablished in each reservoir. Samples of water and periphyton were collected during the dry (August 2013) and the rainy periods (January 2014), while the sediment was sampled only during the dry period. Water abiotic limnological variables were determined and quantitative and qualitative analyses were performed after the oxidation of diatom samples. Results Both reservoirs presented low values of electrical conductivity, pH and nutrients. The diatom community was represented by 30 taxa distributed in 20 genera. The diatom diversity was higher in the plankton, with three exclusive species. All taxa collected from the surface sediments also occurred in the plankton. The periphyton was represented by six taxa that were exclusive to this habitat. Conclusion Our results indicated that the environmental variables were responsible for the limnological changes in the two reservoirs. In the studied reservoirs, the species composition of diatoms differed slightly between the plankton and the surface sediments, while we found a different community in the periphyton, with the presence of exclusive species. The two climatic periods showed differences in the abundance of species, but no considerable differences in the species composition between the two reservoirs were observed.

title: Is thermal stability a factor that influences environmental heterogeneity and phytoplankton distribution in tropical lakes?

description: Abstract Aim To evaluate the effects of environmental heterogeneity promoted by thermal stratification on the distribution of limnologic variables and phytoplankton functional groups (FGs) in two natural lakes. Methods Monthly measurements were performed over a five-year period in the vertical profile of a warm monomitic shallow lake (Lago Carioca) and in a deep and meromictic (Lake Dom Helvécio). Results The vertical zonation generated by the high thermal stability during the stratification period promoted an increase in the spatial heterogeneity and, consequently, in the richness of functional groups of the two lakes. In the epilimnion, the dominance of small chlorophytes and desmids (NA, A and X1, ≤20μm) and larger dinophyceans (Lo, ≥20μm) were associated with high turbulence and light availability and soluble phosphorus limitation. In the metalimnion, the presence of filamentous cyanobacteria (R) and colonial chlorophyceans (F) of larger size (≥20µm) were associated with stable habitats with high concentrations of N-NH4 and P-PO4-3 and light limiting conditions. Comparatively, Lake Dom Helvécio presented a higher richness of FGs in the meta-hipolimnetic layers (SN, P) as well as a higher number of species per functional group. Seasonal changes in the climatic conditions (e.g. the decrease in air temperature with the consequent heat loss) caused the break of the water column stability, which promoted the redistribution of the dissolved nutrient forms and the increase of light limitation in the two lakes during the mixing period. Therefore, there was a drastic reduction in the richness and population biomass of FGs (≤80%). Conclusions Thermal stability and atelomixis were the main driving forces of vertical heterogeneity during the stratification, favoring the coexistence of FGs and, consequently, their increase in richness and biomass.

title: Periphytic algal community in lentic environments of the Upper Paraná River floodplain: seasonal and spatial variation

description: Abstract Aim: This study aimed to evaluate the influence of seasonal variation in the hydrological regime and of limnological variables on species richness of periphytic algae in lakes of the Upper Paraná River floodplain. Methods The study area is located in the last undammed stretch of the Paraná River in this floodplain, in which three lakes were sampled quarterly (May, August and November 2014, and February and May 2015) for one year. The periphytic material was obtained from petioles of the aquatic macrophyte Eichhornia azurea (Sw.) Kunth. Results We registered 149 taxa of periphytic algae, distributed in 9 classes. Algal richness changed as a function of the seasonal dynamics of the Paraná River’s hydrological regime. Water level fluctuations directly influenced periphytic algae species. During periods of high water level, species richness increased. Limnological variables showed a close relationship with the hydrological regime, and the dissolved nutrients and turbidity were the abiotic factors that most influenced the algal community. The following species were present in all lakes: Fragilaria capucina Desmazières, Gomphonema gracile Ehrenberg and Navicula cryptotenella Lange-Bertalot (Bacillariophyceae) and two species of the genus Oedogonium (Oedogoniophyceae). Conclusions The hydrological regime of the Paraná River played an important role in structuring communities of periphytic algae. Seasonal variation in hydrological regime and in limnological variables together influenced the species richness of these organisms in these floodplain lakes.

title: Teaching of Expressive Repertoire to Children Who Are Users of Cochlear Implants: a Literature Review

description: ABSTRACT: The aims of this research were (a) to verify the quantity of scientific productions that described procedures of teaching of expressive repertoire, according to Skinner's verbal categories (1957), to children with cochlear implants; (b) to characterize their methods, considering participants, stimuli, materials and experimental design used; (c) to identify manipulated independent variable and dependent measured variable. The methodology followed the PRISMA model for literature reviews and meta-analyzes; the search was done in the Web of Science with the descriptors and bullet points: "Cochlear Implant", [and] "Children" [and] "Language", [and] "Teaching". We found 39 papers and, after applying the exclusion criteria, we obtained 12 papers for analysis. Among them, eight papers described methodologies of expressive repertoire teaching. The data pointed out that a concentration of international publications between the years 2012 and 2015. The intraverbal operant has been the major target of the interventions found, followed by tact and textual ones. More than 50% of the studies made use of single-subject experimental designs, corroborating with the indications about the importance of this type of design for research in health and education. National publications were not found, although there is a strong line of research in the country. In order to avoid this situation, it is necessary to insert intentionally the research that is known to the set of researches found through systematic reviews. Synthesizing publications that present teaching methodologies to this population may favor Special Education professionals in the elaboration of their interventions and curricula.

title: Changes in the structure of the phytoplankton community in a Nile tilapia fishpond

description: Abstract Aim Our objectives were to recognize species that can serve as biological descriptors and evaluate the changes in the phytoplankton community throughout the grow-out period of the Nile tilapia (Oreochromis niloticus Linnaeus 1758) related to management practices and to limnological variables. Methods Samples from the inflow water and the fishpond were collected for the analysis of limnological variables and the structure of the phytoplankton community. Results In the fishpond, we registered a 1.5 times increase in nitrogen and total suspended solids and a 2 times increase in phosphorous compared to the inflow water. During the grow-out period (113 days), 134 taxa belonging to 10 taxonomic classes were registered. Chlorophyceae (60 taxa) and Cyanobacteria (26 taxa) showed the greatest diversity and abundance of species. The largest biovolumes were recorded in the fishpond. Nanoplanktonic species were the most abundant and represented 35% of the descriptor species in the phytoplankton community of the fishpond. Conclusions The instability of the system associated with the control of the hydraulic retention time as a consequence of management practices, favored the presence of species with small cellular dimensions. The decrease in air and water temperature registered at the end of the grow-out period probably favored the increase and persistence of diatoms. Graphical abstract Spatial variation of the main phytoplanktonic taxa in the fishpond.

title: Responses of the phytoplankton functional structure to the spatial and temporal heterogeneity in a large subtropical shallow lake

description: Abstract Aim Studies on biological communities that take into account only the species composition and abundances (or biomass) and their relative contributions, most of the time, do not reflect their ecological functions, especially considering the wide spatial and temporal variation of large shallow lakes. This paper aimed at evaluating the influence of environmental spatial and temporal heterogeneity on the functional structure of phytoplankton in a subtropical large shallow lake. Methods Seasonal samplings were carried out in 2010 and 2011, in 19 sampling sites distributed along the entire length (90 km) and width (3-10 km) of Lake Mangueira, a large (820 km2 ) and shallow lake (zmean = 2.6 m), comprising the littoral and pelagic zones of the north, central and southern regions. Abiotic variables and phytoplankton functional traits (volume, maximum linear dimension, life forms) and functional groups were analyzed as measures of functional structure. Results The results showed that there was no spatial organization of phytoplankton functional traits during the study. Colonial non-flagellated organisms, organisms with cellular volume between 103 and 104 μm3 and greater than 104 μm3, and with maximum linear dimension between 21 and 50 μm prevailed in all zones and regions. Phytoplankton functional groups and traits responded to resource variation, especially increasing their variety and contribution during spring and summer periods. Conclusions The functional structure of the phytoplankton community in Lake Mangueira, here accessed by functional traits and RFGs, was more conditioned by its environmental temporal variability rather than by the spatial variation, indicating that the resources and life conditions seasonal variation strongly influence the phytoplankton in this ecosystem.

title: The history of UEG’s Journal of Administration: progress and challenges

description: Abstract Scientific journals are important channels adopted by researchers to disseminate the results of their studies. In the area of Administration, this communication becomes important insofar as it disseminates knowledge in the field of management of public and private organizations, the applicability of which may result in society’s development. This article describes the history of the UEG Journal of Administration (RAUEG) in its eight years of existence, based on the analysis of the general data of the publications, to show the advances and challenges faced. The 20 editions published in the period 2010-2017 totaled 132 articles by researchers linked to several Brazilian research and higher education institutions, with most publications in the areas of economics (18%), marketing (17%) and management (13%). Even with the advances made since its creation, there is a need to overcome the barriers that prevent the journal from reaching the level of quality achieved by the major Brazilian journals in the area.

title: Acute Kidney Injury Epidemiology in pediatrics

description: Abstract We performed a search in the MEDLINE database using the MeSH term: "Acute Kidney Injury", selecting the subtopic "Epidemiology", and applying age and year of publication filters. We also searched for the terms: "acute renal failure" and "epidemiology" "acute tubular necrosis" and "epidemiology" in the title and summary fields with the same filters. In a second search, we searched in the LILACS database, with the terms: "acute renal injury", or "acute renal failure" or "acute kidney injury" and the age filter. All abstracts were evaluated by the authors and the articles considered most relevant, were examined in their entirety. Acute Kidney Injury (AKI) -related mortality ranged from 3-63% in the studies included in this review. AKI etiology has marked regional differences, with sepsis being the main cause in developed countries. In developing countries, primary renal diseases and hypovolemia are still a common cause of AKI.
