As previously reported wood of western juniper, Juniperus occidentalis Hook, was collected from nine locations throughout its range in northern California, south-central and central Oregon. Trees for testing were selected, in part, by their stem form and ability to provide useable test material. Trees of unusual size and form were not, however, selected for test trees, but were bypassed in favo...

The present study describes the reproductive ecology of the prostrate shrub Juniperus sabina and the dwarf shrub Artemisia santolinifolia in dry mountain steppes of southern Mongolia. Whereas stands of the juniper are located at the drought limit of the genus’ distributional range, the genus Artemisia is typical of central Asian drylands. Both species produce large numbers of reproductive organ...

Although the distribution and structure of pinyon-juiper woodlands in the southwestern United States are thought to be the result of historic fluctuations in regional climatic conditions, more recent increases in the areal extent, tree density, soil erosion rates and loss of understory plant diversity are attributed to heavy grazing by domestic livestock and interruption of the natural fire reg...

SNPs from nrDNA and trnC-trnD cp DNA for the Caribbean junipers have provided additional insight into the evolution of this group of smooth leaf margined junipers. Comparing leaf terpenoids, RAPDS and SNPs from nrDNA and trnC-trnD cp DNA show that each data set reveals different facets of the relationships. In general, the data sets support four major groups: Juniperus barbadensis lucayana; J. ...

The expected and already observed increment in frequency of extreme climatic events may result in severe vegetation shifts. However, stabilizing mechanisms promoting community resilience can buffer the lasting impact of extreme events. The present work analyzes the resilience of a Mediterranean mountain ecosystem after an extreme drought in 2005, examining shoot-growth and needle-length resista...
