- ... Crepis tectorum L., narrow leaf hawksbeard, first was collected in Alaska in 1974 and by 2004 was a common weed in agricultural fields. Introduction and establishment of a new plant species in a region represents a potential new resource for herbivores, as well as a new competitor for plant species already present. Objectives of this study were to determine the preference for C. tectorum, relative ...

- ... Understanding the population dynamics of a montane/alpine grasshopper species with a disjunct distribution may help to clarify the evolutionary mechanisms of the genus Melanoplus during the Pleistocene era. A total of 215 individuals of one such species, Melanoplus alpinus Scudder, was collected from 43 meadows (5 individuals per meadow) in 10 drainages of four mountain ranges in Wyoming and Monta ...
