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 …

Plant root water uptake (RWU) has been documented for the past five decades from water
stable isotopic analysis. By comparing the (hydrogen or oxygen) stable isotopic …

Although the above and belowground sizes and shapes of plants strongly influence plant
competition, community structure, and plant–environment interactions, plant sizes and …

Dryland ecosystems may be especially vulnerable to expected 21st century increases in
temperature and aridity because they are tightly controlled by moisture availability. However …

Arid environments are characterized by limited and variable rainfall that supplies resources
in pulses. Resource pulsing is a special form of environmental variation, and the general …

Abstract The 'two-layer'and 'pulse-reserve'hypotheses were developed 30 years ago and
continue to serve as the standard for many experiments and modeling studies that examine …

Understanding the influence of vegetation on water storage and flux in the upper soil is
crucial in assessing the consequences of climate and land use change. We sampled the …

Aims To identify approaches to improve our understanding of, and predictive capability for,
mixed tree–grass systems. Elucidation of the interactions, dynamics and determinants, and …

Although water is the most abundant molecule on the Earth's surface, the availability of
water is the factor that most strongly restricts terrestrial plant production on a global scale …

Recent studies suggest that savanna trees in semi-arid areas can increase understorey
plant production. We hypothesized that one of the mechanisms that explains the facilitation …
