Rooting patterns for terrestrial biomes are analyzed and distributions for various plant functional groups are compared and the merits and possible shortcomings of the analysis are discussed in the context of root biomass and root functioning.
Global biodiversity scenarios for the year 2100.
This study identified a ranking of the importance of drivers of change, aranking of the biomes with respect to expected changes, and the major sources of uncertainties in projections of future biodiversity change.

Deep root habits are quite common in woody and herbaceous species across most of the terrestrial biomes, far deeper than the traditional view has held up to now, and has important implications for a better understanding of ecosystem function and its application in developing ecosystem models.
Consequences of changing biodiversity
The large ecological and societal consequences of changing biodiversity should be minimized to preserve options for future solutions to global environmental problems.
Convergence across biomes to a common rain-use efficiency
It is shown that RUE decreases across biomes as mean annual precipitation increases, and during the driest years at each site, there is convergence to a common maximum RUE (RUEmax) that is typical of arid ecosystems.
Primary Production of the Central Grassland Region of the United States
Aboveground net primary production of grasslands is strongly influenced by the amount and distribution of annual precipitation. Analysis of data collected at 9500 sites throughout the central United…
A Generalized Model of the Effects of Grazing by Large Herbivores on Grassland Community Structure
It is suggested that feedback mechanisms between plants and grazing animals are well developed in grasslands with long evolutionary histories of grazing, and switching capabilities in semiarid and subhumid grassland situations are manifest in the rapid switching capabilities of plant species and modes of competition.

In this article we review the main characteristics of the Patagonian climate, the spatial and temporal patterns of the most important climatic variables, and the influence of climate on ecosystem…
Hierarchy of responses to resource pulses in arid and semi-arid ecosystems
The idea that there exists a hierarchy of soil moisture pulse events with a corresponding hierarchy of ecological responses is developed, such that small pulses only trigger a small number of relatively minor ecological events, and larger pulses trigger a more inclusive set and some larger ecological events.
Large Herbivore Foraging and Ecological HierarchiesLandscape ecology can enhance traditional foraging theory

Compared with the prey consumed by predatory animals, the food of large herbivores is much more likely to be widely dispersed over the landscape, rather than concentrated in discrete patches, and the animals confront a series of interrelated foraging problems, each on a different tempo.
