  1. Viability and invasive potential of hybrids between yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria dalmatica)

    Although outcomes of hybridization are highly variable, it is now considered to play an important role in evolution, speciation, and invasion. Hybridization has recently been confirmed between populations of yellow (or common) toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria dalmatica) in the Rocky Mountain region of the United States. The presence of hybrid...

  2. Chapter 2: Effects of fire on nonnative invasive plants and invasibility of wildland ecosystems

    Considerable experimental and theoretical work has been done on general concepts regarding nonnative species and disturbance, but experimental research on the effects of fire on nonnative invasive species is sparse. We begin this chapter by connecting fundamental concepts from the literature of invasion ecology to fire. Then we examine fire behavior characteristics,...

  3. Source habitats for terrestrial vertebrates of focus in the interior Columbia basin: broadscale trends and management implications (Volumes 1-3)

    We defined habitat requirements (source habitats) and assessed trends in these habitats for 91 species of terrestrial vertebrates on 58 million ha (145 million acres) of public and private lands within the interior Columbia basin (hereafter referred to as the basin). We also summarized knowledge about species-road relations for each species and mapped source habitats...
