Mark H. Sorel, Andrew R. Murdoch, Richard W. Zabel, Jeffrey C. Jorgensen, Cory M. Kamphaus, Sarah J. Converse
2023, Ecosphere (14)
Differences in the life history pathways (LHPs) of juvenile animals are often associated with differences in demographic rates in later life stages. For migratory animals, different LHPs often result in animals from the same population occupying distinct habitats subjected to different environmental drivers. Understanding how demographic rates differ among animals...

On the scale-dependence of fault surface roughness
Nicholas M. Beeler
2023, JGR Solid Earth (128)
Defining roughness as the ratio of height to length, the standard approach to characterize amplitudes of single fault, joint and fracture surfaces is to measure average height as a function of profile length. Empirically, this roughness depends strongly on scale. The ratio is approximately 0.01 at a few mm but...
