Biotic and abiotic processes at continent-ocean interfaces cycle a disproportionate mass of carbon and nutrients relative to their global surface area, and microbial activity is a principal determinant of organic and inorganic matter flux in these transition zones. Most studies using modern high-throughput ‘omics techniques to link microorganisms with costal...
Easter Island and Sala y Gomez are part of the Sala y Gomez
Ridge, a broad band of high topography and scattered seamounts
extending ESE from the East Pacific Rise. It has been proposed that
the Sala y Gomez Ridge results from the movement of the Nazca Plate
over a...
The natural gas industry has become essential in many areas in the United States. Currently there is over 37.5 million miles of natural gas distribution lines. A large majority of these lines are polyethylene pipes. With such a large percentage of polyethylene lines in use gas companies are continually looking...
This report presents tables of suspended-sediment data collected from 1956 to 1967 at 10 sites in the Umpqua River basin. Computations based on these data indicate that average annual suspended-sediment yields at these sites range from 137 to 822 tons per square mile.
Because available data for the Umpqua River...
A timber sale is the culmination of many years
of forest management. For many woodland
owners, it is the most significant opportunity
for return on their forestry investments. It also
may be a significant departure from their normal
sphere of operations. Owners may be accustomed
to planting, managing weeds, thinning...
This research explores differences in environmental worldviews and connections to the land globally and more specifically in a case study of NGOs working in the Ecuadorian Cloud Forest. The aims of this project are to investigate different environmental worldviews expressed between western NGOs and non western local NGOs and to...
This report describes how energy is used in at the Hatfield Marine Science Center, and includes recommendations on cost effective steps that could be taken to reduce energy and waste costs. The contents are based on a recent visit to the facilities in Newport, Oregon.
Low reproductive success has been typical of high elevation populations of the Hawaiian goose (Branta sandvicensis) or nēnē. Researchers identified predation and inadequate nutrition as limiting factors. Reproductive success remained low in most years despite on-going predator control programs. I used a supplemental feeding program over two breeding seasons in...
An abundant fruiting of a black morel was encountered in temperate northwestern New South Wales (NSW), Australia, during a mycological survey in Sep 2010. The site was west of the Great Dividing Range in a young, dry sclerophyll forest dominated by Eucalyptus and Callitris north of Coonabarabran in an area...
The critically endangered Maui's dolphin (Cephalorhynchus hectori maui) and the endangered Hector's dolphin (C. h. hectori) are endemic to the coastal waters of New Zealand, where their primary threat is fisheries-related mortality. The Maui's dolphin is among the most critically endangered cetaceans in the world, with its remnant population primarily...
