Mean weights, lengths, and condition factors of three isozyme
phenotypes of lactate dehydrogenase (LDH) enzyme differed significantly
for experimentally reared winter steelhead trout (Salmo
gairdneri) fry. Time of emergence from the gravel was unrelated
to LDH phenotype. Relative mortality of the phenotypes between

of plant species and utilization by cattle, sheep and deer as related
to plant communities and timber management practices and 2) evaluate
the interaction of range use between cattle and deer and between sheep
and deer as affected by site...
Gravity, magnetic and seismic data indicate that the oceanic
crust is 9.7 km thick west of the Continental Borderland. The top
of the mantle is about 12 km deep under the Borderland, and deepens
to 27 km beneath the Peninsular Ranges of Baja California. The
mantle is about 20 km...
