A review of preferential flow and transport through root channels
Abstract Preferential flow can contribute up to 80%–90% of the flow and transport in the vadose zone. The root channels are the most prevalent form of preferential pathways. They create an evolving network of preferential pathways and are biogeochemical hotspots due to preferential transport of nutrients and other organics, colonization of bacteria ...

Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

The alpine wetlands on the eastern Qinghai-Tibet Plateau (EQTP) serve as a critical global ecological barrier. Under the dual pressures of climate change and human activities, these wetland systems face environmental challenges such as retrogressive ...

Abstract In alpine permafrost basins, dry‐season runoff largely depends on subpermafrost groundwater (BPG, deep groundwater), yet cryohydrogeological conditions are complicated by time‐varying hydrothermal regimes. Combined with the storage and regulation effects of permafrost on runoff, hydrograph‐based estimates of the fractional contribution of BPG ...

Abstract Competition for forage between wild ungulates and grazing livestock poses a critical challenge for sustaining grassland ecosystems and pastoral livelihoods. Protected areas (PAs) may mitigate competition, but quantitative multi‐species assessments that simultaneously integrate habitat overlap, forage availability, and conservation ...

Abstract Arctic soils store large amounts of soil organic carbon (SOC), yet landscape‐scale variability remains poorly constrained, especially in complex mountainous regions that can be found across the Arctic. Understanding climate change impacts on Arctic carbon dynamics requires in‐depth knowledge of SOC controls, given multiple drivers and ...

Mapping Groundwater‐Dependent Ecosystems for Contiguous China With Selected Hydroclimatic Windows
Abstract Groundwater‐dependent ecosystems (GDEs) provide critical ecosystem services in arid and semiarid regions and help sustain ecosystems during droughts in humid areas. Accurate mapping of GDEs is essential for improving water resource management and ecosystem conservation.
