Root phosphatase activity is a competitive trait affiliated with the conservation gradient in root economic space

Background:The diversity of resource acquisition strategies of plant roots determines the species coexistence patterns to a certain extent.However,few root physiological traits have been investigated,such as root phosphatase activity(PA)that affects plant phosphorus(P)uptake.Methods:Root PA and classical root functional traits were investigated for 21 coexisting species in a deciduous broad-leaved forest in warm temperate-subtropical transition zone,China.We analyzed the root order variation of absorptive fine root PA,clarified the attribution of root PA in root economic space(RES)and the different P acquisition strategies of co-occurring species based on the multidimensional RES theory,and determined the dominant factors affecting interspecific variation in root PA.Results:There was no distinct pattern of PA variation with root order in the first three root orders of absorptive fine roots,and root PA was constrained by phylogeny.Root PA is a competitive trait affiliated with the conservation gradient in RES.The tight linkages among root PA,mycorrhizal colonization,diameter,specific root length,and nitrogen concentration suggested trade-offs among P acquisition strategies of co-occurring species,i.e.species with long and fine roots acquire inorganic P by actively exploring the soil and secreting phosphatase to mineralize and hydrolyze organic P,while species with short and thick roots obtain P mainly by investing C in mycorrhizal partners.Conclusions:Collectively,our study provides an insight into the forest species coexistence in climatic transition zones,i.e.species coexistence mechanisms based on diverse phosphorus acquisition strategies.

Stock prices and economic activity nexus in OECD countries:new evidence from an asymmetric panel Granger causality test in the frequency domain

This study investigates the stock price–economic activity nexus in 12 member countries of the Organization for Economic Cooperation and Development(OECD)by employing monthly data over the period 1981:1–2018:3.For this purpose,the study uses Granger causality in the frequency domain in the panel setting by decomposing the symmetric and asymmetric fluctuations.This methodology determines whether the predictive power of interested variables is concentrated on quickly,moderately,or slowly fluctuating components.Our findings show that the stock prices have predictive power for future long-term economic activity in the panel setting.However,economic activity has more reliable information for stock prices for negative components.Additionally,empirical findings for asymmetric shocks are not fully consistent with those of symmetric ones.Besides,the country-specific results provide different causal linkages across members and frequencies.These findings may provide valuable information for policymakers to design proper and effective policies in OECD countries regarding the stock market and economic activity nexus.

Participation of Women in the Economic Activity in Cameroon

The aim of this paper is to put forward the explanatory factors of the participation of women in the economic activity in the Cameroonian context characterized by an important and persistent gender gap in terms of participation in the economic activity （more men than women）. The authors carried out, on the basis of data resulting from the DHS-MICS 2011, an analysis using the binomial logistic model. It comes out from this analysis that the significant explanatory variables are the age （which plays at the same time the role of variable of control）, the religion, the ethnic group, the size of the household, the relationship with the head of household, the educational level （of the woman and the husband/partner）, the occupational status of the husband/partner, the household＇s standard of living, and the marital status. According to the results obtained, it would be important to set up policies intended to reinforce the professionalization of the young woman and to fight against the sexist sociocultural norms and practices advocating the ＂sexual division＂ of labor.

Incidence of Stroke among Swedish-Born and Migrant Women<br/>—The Role of Socio-Economic Status, Smoking, and Physical Activity

Introduction: The incidence of stroke has decreased in Sweden as well as in most developed countries, but a high number of migrants have arrived in Sweden, during the last decades, which may have influenced the incidence. Aim: The aim of this study was to examine the incidence of stroke in women, born outside as well as in Sweden. Furthermore, the aim was to examine how socio-economic factors, smoking, and physical activity could modify the risk for stroke. Method: Data from the “Malm&ouml;Diet and Cancer Study” was used for the analysis. In total, 16,857 women were included (14,849 of them born in and 2,008 born outside Sweden), aged 45 - 73 years with a mean age of 57.4 years. Result. A significantly increased relative risk (RR) was found for the incidence of stroke for current smokers in both Swedish-born and migrant women. In Swedish-born women the RR was 1.98 (CI: 1.66 - 2.36) and for migrant women the RR was 1.83(CI: 1.13 - 2.96). The adjusted relative risk for the incidence of stroke in Swedish-born women performing moderate/high physical activity was RR 0.71 (CI: 0.61 - 0.84) and for migrant women it was RR 0.77 (CI: 0.49 - 1.20). The relative risk in relation to low socio-economic circumstances (SES) was significant only for Swedish-born women (RR 0.85 [CI: 0.73 - 0.99]). Among currently smoking Swedish-born women with a low SES the RR was 1.27 (CI: 1.03 - 1.57) in comparison with smoking migrant women, whose RR was 1.68 (CI: 0.92 - 3.09). Conclusion: No differences were found indicating that migrant women in this population had a higher risk as compared to Swedish-born women. However, migrant smoking women were more vulnerable to stroke compared to Swedish-born women. Physical activity was effective in reducing the risk of stroke among the total population and especially in the Swedish-born women. To increase physical activity in middle-aged women, in both migrant and Swedish-born women, is a highly recommended public health strategy.
