Climate warming may drive invasions by exotic plants, thereby raising concerns over the risks of invasive plants. However, little is known about how climate warming influences the growth and competitive ability of exotic plants from their home and introduced ranges. We conducted a common garden experiment with an invasive plant Centaurea maculosa and a native plant Poa pratensis, in which a mix...

INTRODUCTION  Atherosclerosis is a systemic pathological process involving the whole arterial bed. Valvular calcifications are associated with cardiovascular risk factors. Significant carotid stenosis accounts for approximately 20% of cerebrovascular ischemic episodes.  OBJECTIVES  The aim of the study was to assess the relationship between mitral and aortic annular calcifications, increased ...

Small-mammal seed predation is an important force structuring native-plant communities that may also influence exotic-plant invasions. In the intermountain West, deer mice (Peromyscus maniculatus) are prominent predators of native-plant seeds, but they avoid consuming seeds of certain widespread invasives like spotted knapweed (Centaurea maculosa). These mice also consume the biological-control...
