knotweeds (Fallopia japonica, F. sachalinensis and
F. x bohemica) have invaded the western USA and
Canada, as well as other regions of the world. The
distribution of these taxa in western North America,
and their mode of invasion, is relatively unresolved.

Mountain environments are currently among the ecosystems least invaded by non-native
species; however, mountains are increasingly under threat of non-native plant invasion.
The slow pace of exotic plant invasions in mountain ecosystems is likely due to a combination
of low anthropogenic disturbances, low propagule supply, and extreme/steep environmental
gradients. The...
Direct behavioral observations of multiple free-ranging animals over long periods of time and large geographic areas is
prohibitively difficult. However, recent improvements in technology, such as Global Positioning System (GPS) collars
equipped with motion-sensitive activity monitors, create the potential to remotely monitor animal behavior.
Accelerometer-equipped activity monitors quantify animal motion...
