Many studies have looked at human settlements around individual volcanoes for
volcanic risk analyses, but few have done a comparative study to identify possible global
patterns. With the use of Landsat ETM+ data, this study identifies and compares urban
proximity to the Decade Volcanoes to identify volcanic settlement patterns. These...
Fishery dependent data--length distributions, sex ratios, maturity schedules, and species composition of landed catches--are necessary for stock assessments. These data are currently collected by state port biologists using a sampling design that randomly selects samples from a small percentage of a very large target population. Sampling programs may need to...
Nearest-neighbor resampling is a common procedure used by cartographers to
reproject raster data sets. This type of resampling is useful because it retains the data
from the original raster data set. However, during nearest-neighbor resampling some of
the original data will be lost as it is reprojected, while other data...
Bangladesh lies almost entirely on the delta of three major rivers: the Padma (the
Ganges), the Jamuna (the Brahmaputra), and the Meghna. A considerable portion of
Bangladesh has been repeatedly devastated by floods associated with cyclonic storm
surges along its coastal islands and riverine flooding along the rivers traversing the...
Establishment of marine protected areas (MPAs) has been documented to effectively manage marine resource's diversity and enhance fisheries productivity. However, there must be a critical consideration of how these sites are selected and the actual description of the site itself. Its effectiveness is greatly dependent on understanding these habitats and...
Details the development of the OSU 360 virtual tour system (www.oregonstate.edu/osu360) from May 2008 to May 2009. OSU 360 is a collaboration between the Department of Geosciences, University Housing and Dining Services, Central Web Services, Web Communications, and Admissions/Enrollment. This article details the project development from determining goals, distinguishing locations,...
Understanding the movement behavior and foraging strategies of individuals across multiple spatial and temporal scales is essential not only for understanding the biological requirements of individuals but also for linking individual strategies to population level effects. Glacial fjords scattered throughout south-central and southeastern Alaska host some of the largest seasonal...
Montane meadows in the western Cascades of Oregon occupy approximately 5% of the landscape, but contribute greatly to the region's biodiversity. Western Cascades meadows are dynamic parts of the landscape and have contracted by over 50% in the past two hundred years in the HJ Andrews Experimental Forest (hereafter Andrews...
This study compared effects of human and natural wildfire disturbance on age class distribution and associated ecosystem properties of forests in a 15,670 km2 area of the western Cascades of Oregon. The study site is characterized by three forest use types: low elevation, intensively harvested private industrial lands; mid elevation...
Incidental bycatch in commercial fisheries has been identified as a threat to black-footed albatrosses (Phoebastria nigripes) and Laysan albatrosses (P. immutabilis). Effective long-term conservation of these albatrosses necessitates a thorough understanding of their marine distribution, which marine habitats are selected during foraging, and where they are most likely to interact...
