Obtaining accurate estimates of animal abundance is made difficult by the fact that most
animal species are detected imperfectly. Early attempts at building likelihood models that
account for unknown detection probability impose a simplifying assumption unrealistic for
many populations, however: no births, deaths, migration or emigration can occur in the...

Silicic volcanism in the central Oregon Cascade range has decreased in both the size and frequency of eruptions from its initiation at ~40 Ma to present. The reasons for this reduction in silicic volcanism are poorly constrained. Studies of the petrogenesis of these magmas have the potential for addressing this...
The purpose of this report is to characterize the December 2007 storm and long-term storm variability along the Oregon and Washington coast, present the results of a rapid assessment of randomly selected OWEB restoration projects (restoration activities including large wood placement, fish passage, and riparian planting), and based on the...
Eight Tertiary sedimentary and volcanic units crop out in the thesis area. From oldest to youngest they are the: Sager Creek formation (informal); Pittsburg Bluff Formation; Northrup Creek formation (informal); Smuggler Cove formation (informal); Wickiup Mountain and Cannon Beach members (both informal) of the Astoria Formation; the Grande Ronde Basalt,...
Four cross sections are balanced and retrodeformed to 250±50 ka and
975±75 ka to yield crustal shortening amounts and rates for the western
Transverse Ranges of California. The cross sections compare the shortening
that occurs along a transfer zone in which displacement is transferred eastward
from a surface reverse fault...
Deposition of the Middle Devonian part of the Denay Limestone
and Bay State Dolomite in the northern Antelope Range and Fish
Creek Range, respectively, took place on and in front of a carbonate
platform with a lime sand shoal at the shelf edge. In the Givetian part
of the Denay...
This thesis is an effort to formalize and document some of the changes occuring in the Warwar Valley of Gongola State, Nigeria, West Africa. The documentation will comprise a photographic study over time accompanied by an ethnographic narrative. Information gathered from photographic images, field notes and the anthropological record will...

Paleozoic dolomites, limestones, and detrital clastic rocks
were mapped in the Bellevue Peak 15 minute quadrangle in the
southern Mahogany Hills, Nevada. Sedimentary rock units in this
area represent shallow-shelf eastern assemblage deposits.
Shallow-shelf carbonates characterized deposition from at
least Ordovician through Late Devonian time, when clastics derived
from the...
