Research problems linked to this topic
- Ground observations are critical in the validation of soil water content (SWC) estimates from both satellites and land surface models. Portable SWC sensors provide useful information to determine the amount of SWC in the topsoil layer for various applications; however, these probes are not accurate.
- Determination the regional land surface parameters and components of surface radiation balance over heterogeneous landscape is very important and not an easy problem.
- Detecting and measuring changes in the physical and chemical properties of lakes can give us measures of climate changes, and their potential effects, across year, decades, and millennia.
- Vegetation diversity and health is multidimensional and only partially understood due to its complexity.
- The predicted changes to the climate in temperate zones are prone to alter physiological processes of both carbon sequestration and carbon release of terrestrial ecosystems.
- Aeolian dust plays an important role in climate and ocean processes.
- Evidence from experimental grasslands indicated that plant biodiversity modifies the water cycle, but it is unclear if this is also true for established land-use systems.
- Leaf Area Index (LAI) is an important index that reflects the growth status of forest vegetation and land surface processes.
- Radio frequency signals, while propagating through atmosphere, are subject to different propagation mechanisms and conditions.
- Land use change influences the hydrological as well as landscape processes such as runoff and sediment yields.
- The productivity and sustainability of planted forest ecosystems are dependent on the provision of soil nutrients and nutrient cycling.
- Vegetation indices derived from satellite image data have become one o f the primary information sources for monitoring vegetation conditions and mapping land cover change.
- Fire is an important tool in the conservation and restoration of tallgrass prairie ecosystems.
- Moderate grazing intensity is considered the basic requirement to enhance ecosystem function in grasslands.
- the Arctic, sea-ice plays a central role in the functioning of marine food webs and its rapid shrinking has large effects on the biota.
- Soil microbes are an essential component of most terrestrial ecosystems; as decomposers they are responsible for regulating nutrient dynamics, and they also serve as a highly labile nutrient pool.
- Little is known about the combined impacts of global environmental changes and ecological disturbances on ecosystem functioning, even though such combined impacts might play critical roles in shaping ecosystem processes that can in turn feed back to climate change, such as soil emissions of greenhouse gases.
- Nitrogen (N) enrichment can have large effects on mangroves' capacity to provide critical ecosystem services by affecting fundamental functions such as N cycling and primary productivity.
- Based upon species distribution models (SDMs), many studies have predicted that climate change will cause regional extinctions of tree species within the next 50-100 years.
- Litter plays a central role in the nutrient budgets of forests by supplying inflow to nutrient turnover through decomposition.
- Changes in atmospheric temperature and lowering in water-table (WT) are expected to affect peatland nutrient dynamics.
- A proper understanding of variability of soil chemical properties over an area is important for identifying the soil nutrients related production constraints.
