mparing valley width in a neighboring catchment with large deep-seated landslides. In this terrain, anomalously wide valleys tend to occur upstream of ancient large landslides. According to habitat potential models for coho salmon, broad valley segments associated with deep-seated landsliding result in a larger proportion of the channel network with the capacity to provide productive habitat. Because landslides in this area are structurally controlled, our findings suggest a strong link between geologic properties and aquatic habitat realized by geomorphic processes.


Environmental tolerance and range offset of Treptichnus pedum: Implications for the recognition of the Ediacaran-Cambrian boundary Luis A. Buatois et al., Dept. of Geological Sciences, University of Saskatchewan, 114 Science Place, Saskatoon SK S7N 5E2, Canada. Posted online 7 Feb. 2013; http://dx.doi.org/10.1130/G33938.1.

New research by an international team of scientists led by the University of Saskatchewan has revealed novel information about the most important transition in the history of life: the Ediacaran-Cambrian boundary. The Ediacaran-Cambrian boundary (about 541 million years ago) represents a major divide in the history of the biosphere. Ediacaran biotas were dominated by soft-bodied organisms that are now considered for the most part to be unrelated to modern metazoans. On the other hand, the Cambrian witnessed the rapid development of almost all modern groups of animals, including the rise of skeletal faunas, a major evolutionary event known as the Cambrian explosion. Field work undertaken by this research team in South Africa has shown that the fossil burrow used to place the position of this boundary (a zigzag burrow known as Treptichnus pedum) is found in sediments that were laid down in a wide range of shallow-marine settings, and is present not only in deposits that formed offshore in se
