Climate, physical landscapes, and biota interact to generate heterogeneous hydrologic
conditions in space and over time, which are reflected in spatial patterns of species …

Despite the fundamental significance of water to plants and the persisting question of how
competing species coexist, this is the first review of hydrological niches. We define …

Water Relations of Plants and Soils, successor to the seminal 1983 book by Paul Kramer,
covers the entire field of water relations using current concepts and consistent terminology …

▪ Abstract The use of stable isotope techniques in plant ecological research has grown
steadily during the past two decades. This trend will continue as investigators realize that …

Stable isotope studies of hydrogen and oxygen stable isotope ratios of water within plants
are providing new information on water sources, competitive interactions and water use …

In the arid and semiarid regions of North America, discrete precipitation pulses are important
triggers for biological activity. The timing and magnitude of these pulses may differentially …

Ecologists have long been intrigued by the ways co-occurring species divide limiting
resources. Such resource partitioning, or niche differentiation, may promote species diversity …

The persistence of vegetation under climate change will depend on a plant's capacity to
exploit water resources. We analyzed water source dynamics in piñon pine and juniper trees …

A natural abundance hydrogen stable isotope technique was used to study seasonal
changes in source water utilization and water movement in the xylem of dimorphic root …

Summary 1 We introduce a hydraulic soil‐plant model with water uptake from two soil layers;
one a pulse‐dominated shallow soil layer, the other a deeper soil layer with continuous, but …
