Present and future climatic trends are expected to markedly alter water fluxes stores in the hydrologic cycle.In addition, demand continues grow due increased human use a growing population.Sustainably managing resources requires thorough understanding of storage flow natural, agricultural, urban ecosystems.Measurements stable isotopes (hydrogen oxygen) cycle (atmosphere, soils, plants, surface water, groundwater) can provide information on transport pathways, sourcing, dynamics, ages, pools...
Abstract The cells in tree sapwood form a network of interconnected conduits which enables the transport water and nutrients from roots to canopy. Sapwood depth must be assessed when use is estimated sap flow velocities. However, current approaches assess are either not applicable universally, or require expensive instruments, application chemicals laborious field efforts. Here, we present new method, estimates by thermal imaging increment cores. Using low-cost camera for mobile devices,...
<p>Leaf and canopy temperature have long been recognized as an important indicators of plant water status. Recently, unmanned aerial vehicles (UAVs) became arguably the superior platform to acquire leaf temperatures due their low cost high spatiotemporal resolution flexibility compared satellite platforms. However, when interested in absolute individual leaves, thermal cameras is often not sufficient UAV overflight height needs be adjusted. This causes heterogeneous forests...
