The leaf functional traits of angiosperms and gymnosperms in mountain ecosystems significantly influence phyllosphere fungal diversity. These traits are critical for understanding fungal stress resistance and elevational adaptation, which aids in predicting plant responses to climate change.

基于GIS的干热河谷植被恢复分区研究——以攀枝花城市视野区为例
以攀枝花视野区为例,研究了基于GIS的干热河谷区植被恢复适宜性评价及分区方法.在干热河谷植被恢复适宜性评价及分区中,主要考虑对植被类型及植物生长影响较大的海拔高度、坡向、坡度、岩土类型、土层厚度等因素,并采用专家评分法给各影响因子权重和适宜性评价赋值.经过GIS的数据处理、空间分析、模型建立及运算,得到植被恢复适应性评价图,再经过分类、合并,将攀枝花市视野区划分为适宜区、较适宜区、较不适宜区、不适宜区、极不适宜区,得到植被恢复分区图.

通过对山西右玉贾家窑阳坡退耕还林约20年后的4种植被恢复模式(自然恢复草地、油松林、柠条灌丛和油松—柠条林)土壤水分、理化性质、径流量和侵蚀量的测定,探讨了不同植被恢复模式的水土保持效应。结果表明:(1)4种植被恢复模式0—100 cm土层土壤平均含水量无显著差异,油松林和自然恢复草地的土壤容重高于油松—柠条林和柠条灌丛,土壤总孔隙度的变化趋势与容重相反;(2)4种植被恢复模式0—20 cm土层土壤粒度组成、pH、有机质、铵态氮和速效磷无显著差异,硝态氮和速效钾差异明显 ...

Threats posed by land use to water quality in South Africa's strategic water source areas
Abstract Understanding the negative impacts of land use/land cover (LULC) on water quality is key to developing effective integrated catchment management strategies. However, in line with the Integrated Water Resources Management (IWRM) philosophy, this necessitates the generation and application of useful scientific knowledge, which stakeholders and ...

Island restoration to rebuild seabird populations and amplify coral reef functioning
Abstract Mobile organisms like seabirds can provide important nutrient flows between ecosystems, but this connectivity has been interrupted by the degradation of island ecosystems. Island restoration (via invasive species eradications and the restoration of native vegetation) can reestablish seabird populations and their nutrient transfers between ...
