The concept of species redundancy in ecosystem processes is troublesome because it
appears to contradict the traditional emphasis in ecology on species singularity. When …

Namaqualand is a winter-rainfall desert of some 50 000 km 2, located in north-western
South Africa. For a desert ecosystem, the region is characterized by a unique selective …

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 …

Abstract Changes in plant species richness and community composition were investigated
across a fence separating heavily grazed communal and lightly grazed commercial farming …

Altitudinal distribution of life-forms of vascular plants was studied in E Ladakh (W Himalayas,
NW India) along one of the world's most prominent altitudinal gradients, ranging from 4180 …

The Succulent Karoo Biome covers an interrupted belt of unequal depth spanning the
coastal regions near Lüderitz (Namibia), Namaqualand (on and west of the Escarpment), the …

We investigated the effects of winter and summer drought on plants of the Colorado Plateau
in western North America. This winter-cold, summer-hot desert region receives both winter …

This study explored the impacts of sustained heavy grazing in six vegetation types across an
altitudinal and rainfall gradient in the Kamiesberg mountain range in Namaqualand. The …

Three-quarters of a century ago diamond mining was added to livestock grazing and cereal
cropping as a serious cause of landscape degradation in the north-western semi-arid region …

Using new tools (boosted regression trees) in predictive biogeography, with extensive
spatial 23 distribution data for> 19 000 species, we developed predictive models for South …
