| 1 | Experimental evidence for root competition effects on community evenness in one of two phytometer species显示文摘Aims Plant-plant interactions,being positive or negative,are rec-ognized to be key factors in structuring plant communities.However,it is thought that root competition may be less impor-tant than shoot competition due to greater size symmetry below-ground.Because direct experimental tests on the importance of root competition are scarce,we aim at elucidating whether root competition may have direct or indirect effects on commu-nity structure.Indirect effects may occur by altering the overall size asymmetry of competition through root-shoot competitive interactions.Methods We used a phytometer approach to examine the effects of root,shoot and total competition intensity and importance on evenness of experimental plant communities.Thereby two different phytom-eter species,Festuca brevipila and Dianthus carthusianorum,were grown in small communities of six grassland species over three levels of light and water availability,interacting with neighbouring shoots,roots,both or not at all.Important Findings We found variation in community evenness to be best explained if root and shoot(but not total)competition were considered.However,the effects were species specific:in Dianthus communities increasing root competition increased plant community evenness,while in Festuca communities shoot competition was the driving force of this evenness response.Competition intensities were influenced by environmental conditions in Dianthus,but not in Festuca phytometer plants.While we found no evidence for root-shoot interactions for neither phytom-eter species root competition in Dianthus communities led to increased allocation to shoots,thereby increasing the potential ability to perform in size-asymmetric competition for light.Our experiment demonstrates the potential role of root competition in structuring plant communities. | Lina Weiss Linda Schalow Florian Jeltsch Katja Geissler | 2019 | Journal of Plant Ecology2019，12，2： | 1 |

| 4 | An analysis of the Sao Silvestre race between 2007-2021:An increase in participation but a decrease in performance显示文摘This study aimed to investigate the trends of finishers in the Sao Silvestre race in Brazil,taking into account sex,age,and performance levels.A total of 31775 runners(women,n=13847;men,n=17928),aged(45.2±16.8)years,finishers in the Sao Silvestre race between 2007 and 2021,were considered in the present analysis.Data(event year,date of birth,sex,and race times)were downloaded from the official race website.The man-Whitney U test,Spearman correlation,and robust regression model were computed.Participation increased over time for both sexes.Regarding age groups,“31-40 years”(women)and“>60 years”(men)were those with the highest number of finishers.We found a decrease in performance across the years(β=2.45;p<0.005),as well as significant differences in race times for both sexes(U=42.844;p<0.001),with men presenting better performances than women.Over time,it was observed an increase in the performance gap between the sexes,but in general,the performance decreased(β=1.76;p<0.001).Stakeholders should consider improving the strategies to improve women and young people's participation in running events. | Mabliny Thuany Douglas Vieira Elias Villiger Thayse Natacha Gomes Katja Weiss Pantelis T.Nikolaidis Caio Victor Sousa Volker Scheer Beat Knechtle | 2023 | Sports Medicine and Health Science2023，5，4： | 0 |
| 5 | The burden of prolonged sedentary behavior imposed by uberization显示文摘Mobility applications are rapidly growing in cities worldwide due to their convenience and low cost.Mobility applications drivers experience vast flexibility in work hours,often work longer than in fixed-hours jobs,and can constantly transport passengers in their vehicles for up to 12 h;after this,they must go offline for eight consecutive hours before driving again.Nonetheless,drivers have found an easy way around this limitation by switching to other apps and continuing driving.This burden of prolonged work can increase sedentary behavior among mobility applications drivers.Sedentary behavior is any waking activity in which the individual expends 1.5 metabolic equivalents(METs)or less while sitting or reclining.This behavior can increase the risk of detrimental effects on health.In this opinion article,we aim to discuss the possible effects of the burden of prolonged work on the sedentary behavior of mobility applications drivers and propose possible strategies to face this concerning situation. | Thalles Guilarducci Costa Vinnycius Nunes de Oliveira Douglas Assis Teles Santos Ricardo Borges Viana Marilia Santos Andrade Rodrigo Luiz Vancini Katja Weiss Beat Knechtle Claudio Andre Barbosa de Lira | 2023 | Sports Medicine and Health Science2023，5，2： | 0 |
