The Laramide Ranges of the western United States were generated by compressional tectonics in the late Cretaceous and early Tertiary (e.g., Dickinson et al., ; Bird, ; Erslev, ).These crystalline-cored ranges are bounded by vast basins filled with syn- and post-tectonic sediments that partially buried this region tens of millions of years :// We determined spatial, temporal, trait, phylogenetic, and collector biases in c. 5 million herbarium records, representing three of the most complete digitized floras of the world: Australia (AU), South Africa (SA), and New England, USA (NE).

However, with the exception of the western United States, most of these estimates are derived from short-lived trees whose lifetimes may not adequately reflect the complete range of slope processes which can include erosion, deposition, impacts of extreme events VALMORE, C.

Introduction [2] The growing rate of anthropogenically‐derived N deposition worldwide [Galloway, ] has focused attention on the ability of terrestrial ecosystems to withstand or adapt to this nutrient tem responses are variable, ranging from enhanced net primary productivity [Vitousek and Howarth, ] to, at the other extreme, N saturation with associated declines in   In California, it occurs in the San Francisco Bay area, southern Coast, and Peninsular ranges, where it is locally abundant.

It occupies about 65 acres (26 ha) in the Marin Headlands, Marin County, where it was introduced in the s for landscaping and slope stabilization. It now forms a dense cover, with 1 mature shrub per m². Aridity has been a major feature of the Earth's surface for approximately billion years 1, and drylands (here, we use arid, desert and dryland as interchangeable terms) account for the largest.
