12母亲糖尿病、体重指数对子代出生体重及早产的影响显示文摘母亲妊娠前患Ⅰ型糖尿病、妊娠期糖尿病和肥胖增加了子代大于胎龄儿(LGA)和早产的风险,但胰岛素治疗的糖尿病、非胰岛素治疗的Ⅱ型糖尿病以及糖尿病与孕前体重指数(BMI)的联合效应对子代LGA和早产的影响尚不明确。本研究基于芬兰全国出生登记系统信息,调查了2004年1月1日至2014年12月31日期间所有活产儿信息,母亲胰岛素治疗信息从药品报销登记系统中获取、Ⅱ型糖尿病和妊娠期糖尿病诊断信息从保健登记系统中获取。Kong L Nilsson IAK Gissler M 陈然(编译) 2020中华预防医学杂志2020,54,6:0
13Patterns of grassland invasions by trees: insights from demographic and genetic spatial analyses显示文摘Aims Woody invasions into grasslands have increased globally due to changing land use,climate and introduced woody species,but spatial processes generating and sustaining these invasions are not well understood.To gain insight into the patterns of spread of tree populations within grasslands,and to propose a full spatial analytical toolbox for studying native and non-native woody spe-cies spread when long-term data are not available,we tested if 50 years of grassland invasion in Western Carpathians by Norway spruce(Picea abies Karst.)proceeded by one of the two tradi-tionally competing hypotheses of species spread:(i)by frontier expansion,or(ii)by advanced groups established ahead of the population frontier.We also tested whether the pattern of invasion changed over time.Methods We analyzed the spatial demographic and genetic patterns of a Norway spruce population invading a Western Carpathian grass-land using ripley’s L(t)and genetic kinship coefficients(Fij).We mapped and genotyped spruce trees across the invasion front(from the invasion leading edge to fully colonized grassland near the source population)using three demographic classes(adults,juve-niles and seedlings)to approximate the temporal aspects of the invasion.We studied how the spatial patterns of invasion by indi-vidual demographic classes and their genetic kinship varied among adjacent plots established at different distances from the source population(ranging from 0 to 160 m,in 40-m distance increments).Important Findings Juveniles were positively genetically related to adults on fine scales(<4 m),suggesting that adults within the grassland acted as a seed source and accelerated early invasion.However,adults did not act as nucleation centers for the formation of advanced juvenile groups.Instead,geneti-cally unrelated juveniles formed groups independently of adults.These groups were small and separate at the leading edge but they increased in size and graded into a continuous zone near the source population.Thus,juvenile recruitment occurred as a frontier expansion near the source population and as advanced groups controlled by environmental variation at the leading edge.unlike juveniles,seedlings were clustered on all scales across the invasion front and formed groups around adult crowns at the invasion leading edge.The bulk of seedling establishment occurred at intermediate distances from the source population,indepen-dently from the adults,suggesting that the invasion front continued to expand as a frontier,gradually coalescing with the advanced groups at the leading edge.Thus,the grassland invasion was driven by a gradual frontier expansion of the original population during the first 50 years,with advanced groups enhancing but not driving the invasion process.Frontier expansion appeared more important as a mechanism of woody species spread early in the invasion process in this study,while advanced groups may play a larger role over longer temporal scales.Martin Dovčiak Richard Hrivnák Karol Ujházy Dušan Gömöry 2015Journal of Plant Ecology2015,8,5:0
