| 1 | How do altitude and soil properties influence the taxonomic and phylogenetic structure and diversity of Brazilian páramo vegetation?显示文摘Altitude and environmental variables such as edaphic properties are considered determinants of species distribution and community composition in mountain ecosystems.Here,we aimed to outline the effects of distinct mountain peaks,altitude and soil properties on community composition,species density,phylogenetic structure and diversity of angiosperm páramo communities from the Serra do Brigadeiro State Park,Minas Gerais,southeastern Brazil.For that,we identified all angiosperm species found in 300 plots(1 m×1 m)from three mountain peaks,measured soil depth and analyzed soil fertility and texture in each plot.To reduce the number of soil variables and species composition,we computed principal coordinates based on soil properties and principal coordinates based on species-plot matrix for each plot.Furthermore,we computed the standard effect sizes of the mean phylogenetic pairwise distance and the mean nearest phylogenetic taxon distance for each plot to investigate differences in the degree of relatedness among coexisting species.We compared differences in response variables between peaks and modelled them in function of altitude and principle components of soil properties using mixed effect models.Species density and phylogenetic diversity differed between peaks,but,contrary to the previous findings,no relationships between species richness or phylogenetic diversity and altitude or soil properties were found,indicating that further investigations are necessary to understand the altitude-biodiversity relationship in Brazilian páramo vegetation.Community composition differed between peaks and depended on altitude,soil properties and interactions between them,indicating that upward shifting of bioclimatic conditions due to climate changes may alter communities of this ecosystem.Phylogenetic structure differed between peaks and was influenced by altitude and soil properties.As phylogenetic clustering increased with altitude,eventual upward movements of species in Brazilian páramo vegetation due to climate change may alter community composition and the degree of relatedness among coexisting species,increasing the risk of species from higher altitudes to disappear.Therefore,conservation priorities arise for higher landscape portions,where these high altitude species may find refuges. | Markus GASTAUER Jan THIELE Stefan POREMBSKI Andreza Viana NERI | 2020 | Journal of Mountain Science2020,17,5: | 4 |
| 2 | Plant diversity and community structure of Brazilian Páramos显示文摘In Eastern South America, high altitude grasslands represent a mountain system that has a high number of endemic species. However, studies on the ecology of plant communities in these environments remain scarce. We aimed to evaluate the patterns of biodiversity and structure of plant communities from rocky outcrops in high altitude grasslands of three areas at the Caparaó National Park, southeastern Brazil, by sampling 300 randomly distributed plots. Then, we compared the floristic composition, relative abundance, and biological and vegetation spectra among areas. We classified species as endemic and non-endemic and verified the occurrence of endangered species. Species richness was evaluated by rarefaction analysis on the sampling units. The importance value and species abundance distribution(SAD) models were assessed. We also performed an indicator species analysis. We sampled 58 species belonging to 49 genera and 32 families. The number of species decreased with increasing altitude, with significant differences being observed among areas regarding richness, abundance, and cover. Of the total number of species, 10 are endemic to the Caparaó National Park and 17 are listed on the Brazilian Red List of endangered species. The dominant families on all peaks were Asteraceae and Poaceae. The SAD models showed lognormal and geometric distributions, corroborating the fact that 10 species that were common to all three areas were also the most dominant ones in the communities and showed the highest importance values, which ranged between 35% and 60%. Indicator species analysis revealed that 28 species(48.27%) were indicators. Of these, 42.85% had maximum specificity, meaning that they occurred only in one area. Thus, the number of species per life form ratio was similar among areas, yet vegetation spectra differed, especially for hemicryptophytes. The altimetric difference among the areas showed to be a very important driver in the community assembly, influencing the evaluated variables, however, other drivers as soil depth, slope and water could also influence the community structure on a smaller and local spatial scale. | prímula viana campos pedro manuel villa jaquelina alves nunes carlos e.g.r.schaefer stefan porembski andreza viana neri | 2018 | Journal of Mountain Science2018,15,6: | 2 |
| 3 | Fine-scale habitat differentiation shapes the composition, structure and aboveground biomass but not species richness of a tropical Atlantic forest显示文摘Evaluating the influences of fine-scale habitat heterogeneity on the composition,diversity,structure and functioning of forests is critical to understand how tropical forests will respond to climate change and devise forest management strategies that will enhance biodiversity conservation and aboveground biomass stock.Here,we hypothesized that topographic and soil factors determine fine-scale habitat differentiation,which in turn shape community composition,species richness,structure and aboveground biomass at the local scale in tropical forests.To test this hypothesis,we selected two areas(each 100×100 m)with contrasting fine-scale topographic conditions where all trees,palms and lianas with a diameter at breast height ≥ 10 cm were tagged and identified to species.In each selected area,100 subplots of 10×10 m were established.We mainly found that higher topographic variability caused higher habitat differentiation with changes in species composition and community structure,but did not change species richness.Our habitat-scale analyses indicated that,in the less heterogeneous area,the distribution of species was more uniform along a fine-scale topographical gradient with no variation in convexity,which induced changes in structure and aboveground biomass,but not in species richness.The nonsignificant relationship between species richness and aboveground biomass may be attributable to species redundancy or functional dominance.This study suggests that environmental filtering is a fundamental process for shaping community assembly and forest functioning along a local topographical gradient in tropical forests. | Alice Cristina Rodrigues Pedro Manuel Villa Arshad Ali Walnir Ferreira-Junior Andreza Viana Neri | 2020 | Journal of Forestry Research2020,31,5: | 2 |

| 10 | Comprehensive analysis of HFE gene in hereditary hemochromatosis and in diseases associated with acquired iron overload显示文摘BACKGROUND Patients with hepatitis C virus(HCV) and hepatocellular carcinoma(HCC) may or not develop iron overload(IO),which is associated with worst prognosis,because can cause serious damage to organs.HFE gene controls the iron uptake from gut,particularly in patients with hereditary hemochromatosis(HH).AIM To identify associations between HFE coding region in patients exhibiting hereditary hemochromatosis and in diseases associated with acquired IO.METHODS We sequenced exons 2 to 5 and boundary introns of HFE gene,evaluating all polymorphic sites in patients presenting hereditary(hemochromatosis) or acquired iron overload HCV and HCC) and in healthy controls,using Sanger sequencing.We also determined the ensemble of extended haplotype in healthy control individuals,including several major histocompatibility complex loci,using sequence specific probes.Haplotype reconstruction was performed using the Arlequin and Phase softwares,and linkage disequilibrium(LD) between histocompatibility loci and HFE gene was performed using the Haploview software.RESULTS The HFE*003 allele was overrepresented(f = 71%) and HFE*001 allele was underrepresented(f = 14%) in HH patients compared to all groups.A strong linkage disequilibrium was observed among the H63 D-G,IVS2(+4)-C and C282 YG gene variants,particularly in HH;however,the mutation IVS2(+4)T>C was not directly associated with HH susceptibility.The HFE*001/HFE*002 genotype conferred susceptibility to HCC in HCV patients exhibiting IO(P = 0.02,OR =14.14).Although HFE is telomeric to other histocompatibility genes,the H63 DG/IVS2(+4)-C(P ≤ 0.00001/P ≤ 0.0057) combination was in LD with HLA-B*44 allele group in healthy controls.No LD was observed between HFE alleles and other major histocompatibility loci.CONCLUSION A differential HFE association was observed for HH and for diseases associated with acquired IO(HCV,HCC).Since HFE is very distant from other histocompatibility loci,only weak associations were observed with these alleles. | Wagner Narciso de Campos Juliana Doblas Massaro Eduardo Luiz Rachid Can?ado Cláudia Emília Vieira Wiezel Aguinaldo Luiz Sim?es Andreza Correa Teixeira Fernanda Fernandes de Souza Celso Teixeira Mendes-Junior Ana de Lourdes Candolo Martinelli Eduardo Ant?nio Donadi | 2019 | World Journal of Hepatology2019,11,2: | 1 |
| 11 | The influence of soil on vegetation structure and plant diversity in different tropical savannic and forest habitats显示文摘Aims Soil plays an important role in the formation and heterogene-ity of habitats and thus can cause changes in vegetation struc-ture and plant diversity.The differentiation between Cerrado/savanna and forest is well known,but the relationship between soil and habitats from savannic or forest formations still needs to be better understood,particularly in tropical ecotonal areas.We studied the association between attributes of plant com-munities,namely structure and diversity,and physicochemical characteristics of soils in the Caatinga domain at the transition to Cerrado in Brazil.Methods Chemical and physical analyses of soils were performed in samples of 38 plots from savannic formations and 30 plots from forest forma-tions.Vegetation was characterized floristically and structurally in all plots,five habitats being assessed in each plant formation.Soil features and vegetation parameters were highly distinct among the different habitats.Important Findingsin general,forest habitats were more nutrient rich than savannic formation.Furthermore,soil variables showed effects both on vegetation structure and on its species diversity,more pronouncedly in the savannic formations.Habitats were structurally distinct,and diversity differed between savannic and forest communities;however,a higher differentiation occurred when the savannic formation habitats were compared among them.Although plant diversity did not differ among forest formation habitats,soil attributes showed a close relationship with edaphic factors and can contribute for similar vegetation.The soil-vegetation relationship in highly diverse ecotonal landscapes is important from the conservation biology point of view and aid in the execution of proactive plans for the maintenance of biodiversity.Thus,we noticed that diversity and soil behaves distinctly between savannic and forest communities. | Priscyla Maria Silva Rodrigues Carlos Ernesto Gonçalves Reynaud Schaefer Jhonathan de Oliveira Silva Walnir Gomes Ferreira Júnior Rubens Manoel dos Santos Andreza Viana Neri | 2018 | Journal of Plant Ecology2018,11,2: | 1 |
| 12 | Soil and altitude drive diversity and functioning of Brazilian Páramos(campo de altitude)显示文摘Aims the vegetation on Brazilian Páramos consists of assemblages that are driven mainly by the influence of strong environmental filtering.It is very important to understand the effect of environmental varia-tion on taxonomic diversity and on functional diversity.considering the lack of information about the functional diversity in Brazilian Páramos,we analyzed for the first time the effects of altitude and edaphic attributes on functional traits,as well as on taxonomic and functional diversity.We also wanted to answer the questions:Which ecological strategies are favorable in high-altitude grassland?Does soil attributes determine distributions of traits in high-altitude grassland?considering the studied altitudinal gradient is altitude an important variable in the community assembly?Methods the study was conducted on three mountains:Mammoth(1850 m),Elephant(1790 m)and totem(1690 m)in Serra do Brigadeiro State Park,Minas Gerais State,Brazil.those mountains represent the‘Serra das cabeças’,a smaller ridge that is surrounded by the Atlantic Forest,one of the 25 hotspot of biodiversity.the samples were taken using 100 plots of 1 m2 per mountain that were randomly distributed.All plants except mosses were sampled.the taxonomic diversity was evaluated using richness,Shannon diversity,effective number of species and Pielou evenness.For the functional diver-sity,we considered the functional richness,functional evenness and functional divergence.Generalized linear models(GLM/Poisson and quasi-Poisson)were used to evaluate the effect of abiotic variables(altitude,soil depth and soil chemical attributes)on biotic variables(number of species and individuals,life form,dispersal and fruit type)and ordinary least squares regression to evaluate the effect of abiotic variables on the functional and taxonomic diversity.Important Findingsthe soil variables presented a considerable edaphic gradient associated with altitude.the soil in Serra das cabeças plays an important role for the plant diversity:richness and diversity index were positively related with fertility.With regard to the life form,nanophanerophytes tended to increase with altitude and soil depth,while therophytes tended to decrease with altitude.the dispersal type was also associated with the abiotic variables:autochory decreases with altitude,while zoochory increases.Functional richness increases with fertility and the functional evenness with altitude.the studied gradient showed that altitude is working as a filter for functional traits and indices and is,together with soil attributes,an important determinant for the distribution of plants on Brazilian Páramos. | Andreza Viana Neri Gladson Ramon Alves Borges João Augusto Alves Meira-Neto Luiz Fernando Silva Magnago Ian Michael Trotter Carlos Ernesto GRSchaefer Stefan Porembski | 2017 | Journal of Plant Ecology2017,10,5: | 1 |

| 17 | Efects of topographic variability and forest attributes on fne-scale soil fertility in late-secondary succession of Atlantic Forest显示文摘Background:Understanding how soil fertility changes due to topographical conditions and forest attributes is an essential premise for local-scale forest management practices.We evaluated the efects of topographic variables and forest attributes on soil fertility along a local topographical gradient in a Brazilian Atlantic Forest.We hypothesised that soil fertility is positively afected by topographic variability and forest attributes(structure and diversity).We used tree species richness,composition,abundance,and aboveground biomass as forest attributes.We analysed two 1-ha for‑est patches with contrasting topographical conditions.We used diferent linear mixed efects models(LMMs)to test the main efects of diferent forest attributes and topography variables on soil fertility.Results:The results showed that higher topographic variability determines soil fertility along a fne-scale gradient.The frst two axes of the PCA explained 66.8%of the variation in soil data,with the frst axis(PCA_(1))explaining 49.6%of the variation in soil data and positively correlating with fertility-related soil properties.The second axis(PCA_(2))explained 17.2%of the variation in topographical data and positively correlated with convexity(the elevation of a plot minus the average elevation of all immediate neighbour plots)and elevation.Our best models showed that topo‑graphic variables(elevation and convexity)are the main predictors that afect fne-scale soil fertility.Conclusions:Our study demonstrates that the topographic variability,mainly elevation and convexity,determines fne-scale soil fertility in an Atlantic Forest.These results advance our understanding that context-dependent condi‑tions based on topography and soil properties have a high variability at a fne scale,which can infuence variations in forest attributes(i.e.,species distribution,diversity and structure of tree communities).In addition,the information generated in this research may be important for planning forest restoration activities(passive and active)based on the high variability of environmental variables at a fne scale. | Alice Cristina Rodrigues Pedro Manuel Villa Walnir Gomes Ferreira‑Júnior Carlos Ernesto RGSchaefer Andreza Viana Neri | 2021 | Ecological Processes2021,10,1: | 0 |

| 20 | Understanding how environmental heterogeneity and elevation drives the distribution of woody communities across vegetation types within the campo rupestre in South America显示文摘The campo rupestre sensu lato is a vegetation type that occurs in South American mountains,supports a distinctive flora characterized by high rates of endemism,high herbaceous species richness and often-neglected but also species-rich of the arboreal stratum.We aimed to investigate how environmental factors and elevation are associated with the distribution and diversity of woody species in different rupestrian vegetation types across South America.Using a database of 2,049 woody species from 185 sites across four vegetation types within the campo rupestre,we assessed how the vegetation types were grouped according to their floristic composition and number of shared indicator species,as well as by using different beta diversity indices.The most important variables from a set of 27 variables(e.g.altitude,geo-edaphic and climatic)explaining species distribution were identified using redundancy analysis(RDA)and variation partitioning methods.The distribution of vegetation types was related to both environmental and spatial fractions,with a set of 17 variables retained(e.g.rockiness,grass cover and temperature seasonality as the most important variables).There was an association between the floristic composition of each vegetation type and the elevation range.Although the identified vegetation types are floristically related,they are distinguished by exclusive and habitat-specialist woody species.This uniqueness of vegetation types should be considered in terms of complementarity for the conservation of campos rupestres. | Marcelo Leandro BUENO Vanessa Leite REZENDE Luiza Fonseca A.DE PAULA João Augusto Alves MEIRA-NETO JoséRoberto Rodrigues PINTO Andreza Viana NERI Vanessa PONTARA | 2021 | Journal of Mountain Science2021,18,5: | 0 |
