This review surveys the basic theories, observational methods, satellite algorithms, and land
surface models for terrestrial evapotranspiration, E (or λE, ie, latent heat flux), including a …

Arid and semi-arid environments correspond to one-third of the Earth's terrestrial surface. In
these environments, precipitation is an essential and limiting element for vegetation growth …

Published eddy covariance measurements of carbon dioxide (CO2) exchange between
vegetation and the atmosphere from a global network are distilled, synthesised and …

The net ecosystem CO2 exchange (NEE) between a Mojave Desert ecosystem and the
atmosphere was measured over the course of 2 years at the Mojave Global Change Facility …

This synthesis reviews current knowledge of pinyon and juniper ecosystems, in both
persistent and newly expanded woodlands, for managers, researchers, and the interested …

Net ecosystem productivity (NEP) was measured on shortgrass steppe (SGS) vegetation at
the USDA C entral P lains E xperimental R ange in northeastern C olorado from 2001 to …

Rainfall pulses can significantly drive the evolution of the structure and function of desert
ecosystems, and understanding the mechanisms that underlie the response of desert plants …

Biological activity in arid grasslands is strongly dependent on moisture. We examined gas
exchange of biological soil crusts (biocrusts), the underlying soil biotic community, and the …

This study investigates the causes for, and distribution of, unimodal versus bimodal
seasonal cycle of vegetation greenness in the Southwest United States using extensive site …

Spatial and temporal patterns of soil water are major determinants of net primary production
and plant functional composition in arid and semiarid ecosystems which cover …
