Scaling local species-habitat relations to the larger landscape with a hierarchical spatial count model
W.E. Thogmartin, M. G. Knutson
2007, Landscape Ecology (22) 61-75
Much of what is known about avian species-habitat relations has been derived from studies of birds at local scales. It is entirely unclear whether the relations observed at these scales translate to the larger landscape in a predictable linear fashion. We derived habitat models and mapped predicted abundances for three...

Eo-Ulrichian to Neo-Ulrichian views: The renaissance of "layer-cake stratigraphy"
Carlton E. Brett, P.I. McLaughlin, G.C. Baird
2007, Conference Paper, Stratigraphy
Classical notions of "layer-cake stratigraphy" have been denigrated as representing an antiquated "Neptunian" view of the geologic record with the American paleontologist-stratigrapher E.O. Ulrich vilified as its quintessential advocate. Some of the extreme "layer-cake" interpretations of E.O. Ulrich are demonstrably incorrect, especially where applied in marginal marine and terrestrial settings....
