Biodiversity,large trees,and environmental conditions such as climate and soil have important effects on forest carbon ***,recent studies in temperate forests suggest that the relative importance of these factors depends on tree mycorrhizal associations,whereby large-tree effects may be driven by ectomycorrhizal(EM)trees,diversity effects may be driven by arbuscular mycorrhizal(AM)trees,and environment effects may depend on differential climate and soil preferences of AM and EM *** test this hypothesis,we used forest-inventory data consisting of over 80,000 trees from 631 temperate-forest plots(30 m×30 m)across Northeast China to examine how biodiversity(species diversity and ecological uniqueness),large trees(top 1%of tree diameters),and environmental factors(climate and soil nutrients)differently regulate aboveground carbon stocks of AM trees,EM trees,and AM and EM trees combined(*** aboveground carbon stock).We found that large trees had a positive effect on both AM and EM tree carbon ***,biodiversity and environmental factors had opposite effects on AM *** tree carbon ***,the two components of biodiversity had positive effects on AM tree carbon stocks,but negative effects on EM tree carbon *** heterogeneity(mean annual temperature and soil nutrients)also exhibited contrasting effects on AM and EM tree carbon ***,for the total carbon stock,the positive large-tree effect far surpasses the diversity and environment *** is mainly because when integrating AM and EM tree carbon stock into total carbon stock,the opposite diversity-effect(also environment-effect)on AM *** tree carbon stock counteracts each other while the consistent positive large-tree effect on AM and EM tree carbon stock is *** summary,this study emphasized a mycorrhizal viewpoint to better understand the determinants of overarching aboveground carbon profile across regional forests.

Validation and reproducibility of the Heidelberg Edge Perimeter in the detection of glaucomatous visual field defects

International Journal of Ophthalmology(English edition) 2019年第4期12卷 577-581页

作者： Qi N.Cui Priyanka Gogt jonathan M.Lam Safa Siraj Lisa A.Hark jonathan S.myers L.Jay Katz Michael Waisbourd Glaucoma Research Center Wills Eye Hospital Scheie Eye Center University of Pennsylvania Department of Ophthalmology Tel Aviv Sourasky Medical Center affiliated to the Sackler Faculty of Medicine Tel Aviv University

AIM: To validate the ability of the Heidelberg Edge Perimeter(HEP) in detecting glaucomatous visual field(VF) defects compared to the Octopus Visual Field(OVF) Analyzer and to determine the test-retest repeatability of both ***: This prospective, cross-sectional study was conducted at Wills Eye Hospital, Philadelphia, PA. Glaucoma subjects and unaffected controls underwent VF testing using HEP standard automated perimetry(SAP) Ⅲ 30-2 Adaptive Staircase Thresholding Algorithm(ASTA) FAST protocol and OVF G-TOP white-on-white strategy. Testing order was randomized. Pearson's correlation coefficient was calculated for both mean deviation(MD) and pattern standard deviation/square root of loss of variance(PSD/s LV). Receiver operating characteristic(ROC) curves were used to determine the diagnostic abilities of both modalities. Glaucoma subjects returned for repeat testing and intraclass correlation coefficients(ICCs) were calculated to assess test-retest repeatability. RESULTS: Seventy-nine subjects with glaucoma and 36 unaffected controls were enrolled. HEP and OVF were significantly correlated for both MD(r=-0.84; P<0.01) and PSD/s LV(r=0.79; P<0.01). Areas under the ROC curves(AUCs) were also comparable between HEP and OVF for both MD(0.74 and 0.79, respectively; P=0.26) and PSD/sL V(0.74 and 0.82; P=0.08). ICC was high for both HEP (0.96 for MD, 0.95 for PSD/s LV) and OVF(0.82 and 0.88, respectively). Mean test duration(min) was significantly shorter for OVF(2.63) compared to HEP(5.15; P<0.01). CONCLUSION: HEP and OVF show strong correlation for both MD and PSD/s LV, and have similar validity for detecting glaucoma. The test-retest repeatability is high for both HEP and OVF, however the average testing duration of HEP is significantly longer than that of OVF.
