J. W. Park, C. H. Moon, A. Harmache, A. R. Wargo, M. K. Purcell, M. Bremont, Gael Kurath
2011, Journal of Fish Diseases (34) 115-129
Previously, we demonstrated that a representative M genogroup type strain of infectious haematopoietic necrosis virus (IHNV) from rainbow trout grows well in rainbow trout‐derived RTG‐2 cells, but a U genogroup type strain from sockeye salmon has restricted growth, associated with reduced genome replication and mRNA transcription. Here, we analysed further...

Dustin A. Wood, Amy G. Vandergast, A. Lemos Espinal, Robert N. Fisher, A.T. Holycross
2011, Molecular Ecology (20) 3856-3878
Glacial–interglacial cycles of the Pleistocene are hypothesized as one of the foremost contributors to biological diversification. This is especially true for cold‐adapted montane species, where range shifts have had a pronounced effect on population‐level divergence. Gartersnakes of the Thamnophis rufipunctatus species complex are restricted to cold headwater streams in the highlands of...

Constraints on the long‐period moment‐dip tradeoff for the Tohoku earthquake
Victor C. Tsai, Gavin P. Hayes, Zacharie Duputel
2011, Geophysical Research Letters (38)
Since the work of Kanamori and Given (1981), it has been recognized that shallow, pure dip‐slip earthquakes excite long‐period surface waves such that it is difficult to independently constrain the moment (M0) and the dip (δ) of the source mechanism, with only the product M0 sin(2δ) being well constrained. Because of this,...
