Freshwater mussels in western North America are threatened by water diversions, climate change, loss of required host fish, and other factors, and have experienced marked decline in the past several decades. All four of the primary lineages (potentially species) of freshwater mussels in the western U.S. and Canada are widespread and have somewhat generalist host fish requirements. Of these lineages, perhaps the most poorly understood and of greatest conservation concern is Gonidea angulata (Rocky Mountain ridged mussel). Gonidea is a monotypic genus occurring only in the western continental U.S. and southern Canada. Here we describe the patterns of genetic variation …

Cenozoic Extensional Processes And Tectonics In The Northern Rocky Mountains, Susanne U. Janecke

Extension has shaped the crust of the Northern Rocky Mountains for more than a billion years. Rifting produced the Belt basin shortly after 1.5 Ga and initiated the Paleozoic passive margin. Mesozoic to early Cenozoic convergence pro-duced the Cordilleran fold-and-thrust belt, the uplifts of the Rocky Mountain foreland (Laramide) and an unusually broad Challis arc in the northern Rocky Mountains. The struc-tural grain of the contractional belts, basement features, and the rheology of the Idaho batho-lith influenced the locus, kinematics and ge-ometry of the >55 m.y. of extension that fol-lowed. Sparse data suggest that extension may have begun in the …
