Why is there so little biodiversity in desert biomes?

What are the issues of having low biodiversity in hot deserts?

Human exploitation of fragile ecosystems can lead to the droughts and arid conditions characteristic of desertification. Effects include land degradation, soil erosion and sterility, and a loss of biodiversity, with huge economic costs for nations where deserts are growing.
