The Russian treeline is a dynamic ecotone typified by steep gradients in summer temperature and regionally variable gradients in albedo and heat flux. The location of the treeline is largely controlled by summer temperatures and growing season length. Temperatures have responded strongly to twentieth-century global warming and will display a magnified response to future warming. Dendroecologica...

Many factors can influence the structures and distributions of plant communities. Plant diversity swamp forests reflect responses to water stress conditions. We evaluated floristic diversity, structure, composition regenerating shrub-tree species six in veredas ecosystems (northern Minas Gerais, Brazil), similarities between them. All individuals ? 1 cm diameter at ground level < 3 breast heigh...

We analyzed the tree-rings ?18O of Abies spectabilis (fir) growing at subalpine treeline ecotone in Magguchatti valley. The valley is located Indian summer monsoon (ISM) dominated region western Himalaya and also receives snow precipitation derived by westerly disturbances (WDs) during winter months. 60 year developed (1960–2019 CE) tree-ring chronology revealed a strong positive correlation wi...

Climate change is affecting every aspect of human activities, especially the agriculture. In China, extreme drought events caused by climate change have posed a great threat to food safety. In this work we aimed to study the drought risk of maize in the farming–pastoral ecotone in Northern China based on physical vulnerability assessment. The physical vulnerability curve was constructed from th...

Soil properties are well known to affect vegetation, but the role of soil heterogeneity in the patterning of vegetation dynamics is poorly documented. We asked whether the location of an ecotone separating grass-dominated and sparsely vegetated areas reflected only historical variation in degradation or was related to variation in inherent soil properties. We then asked whether changes in the c...

Background: Diabetes mellitus has several complications. The Late diagnosis of diabetes in people leads to the spread of complications. Therefore, this study has been done to determine the possibility of predicting diabetes type 2 by using data mining techniques. Methods: This is a descriptive-analytic study that was conducted as a cross-sectional study. The study population included people re...

The echolocation calls of the noctule bat Nyctalus noctula (Schreber, 1774) were recorded at night, from June to August 1991, using a QMC S200 bat detector, in 5 habitats (river, forest-meadow ecotone, village, coniferous forest, deciduous forest) of the Białowieża Primeval Forest (eastern Poland). Two main kinds of signals were identified: search calls and feeding buzzes. Acoustic activity was...
