In northern New Mexico, complex interactions among climate, land use, and the associated reduction of surface fire in forest and savanna communities facilitated the expansion of pinon-juniper woodlands. Because increasing tree cover can outcompete he

An overstory thinning and slash mulch treatment designed to improve ecohydrologic condition of degraded transitional (pinon–juniper) woodland sites was evaluated at four sites over a cumulative 16-year period beginning in 1994. Study sites were loc

Apparent changes in the local occurrence and regional extent of southwestern U.S. pinon–juniper woodlands since Euro-American settlement (i.e. historic expansion) are widely reported. These changes are commonly attributed to rapid onset of intensiv

Pinon–juniper is a major vegetation type in western North America. Effective management of these ecosystems has been hindered by inadequate understanding of 1) the variability in ecosystem structure and ecological processes that exists among the di

SUMMARY 1. Wildfires are often followed by severe, sediment-laden floods in burned catchments. In this study, we documented resistance and resilience of stream insect communities to repeated postfire flash floods in a ‘burned stream’. We employed

The piñon (Pinus edulis Engelm.)-juniper [Juniperus monosperma (Engelm.) Sarg.] woodlands of Bandelier National Monument are experiencing accelerated erosion. Earlier studies suggest that causes of these rapidly eroding woodlands are related to an u

Growth of triazine-resistant and -susceptible biotypes of Solanum nigrum was studied over a range of temperatures to test whether resistant biotypes show reduced performance under high temperatures. Each biotype was represented by parental lines and

Abies (fir) is widely considered to consist of two species in the eastern United States, A. balsamea (L.) Mill, and A. fraseri (Pursh.) Poir., distinguished by relative cone bract to subtending cone scale lengths and number of leaf hypodermal cells.
