A Demographic Study of Joshua Tree’s Response to Climate Change.

Global climate change is predicted to affect the distribution of many organisms through both regional extinctions and range expansions. We examined the population ecology of Joshua trees (Yucca brevifolia) in and around the Pahranagat range in Nevada. Using empirical demographic data and simulations of demographic and range changes under various environmental conditions, we evaluated evidence that Joshua Trees are expanding their range in a northern direction in response to climate change. Although empirical data suggest an excess of seedlings along the northern edge of the range, simulations suggest that this pattern is not necessarily indicative of population expansion. Additional data and analytical approaches may be needed to determine the effects of climate change on Joshua Trees.
