Multiple steroid and thyroid hormones detected in baleen from eight whale species

Creator:: Lysiak, Nadine S., Moore, Michael J., Hunt, Kathleen E., Robbins, Jooke, Seton, Rosemary E., Buck, C. Loren, and Torres, Leigh G.
Abstract:: Recent studies have demonstrated that some hormones are present in baleen powder from bowhead (Balaena mysticetus) and North Atlantic right (Eubalaena glacialis) whales. To test the potential generalizability of this technique for studies of stress and reproduction in large whales, we sought to determine whether all major classes of steroid...

History of Entomopathogenic Nematology

Creator:: Poinar, George O., Jr. and Grewal, P. S.
Abstract:: The history of entomopathogenic nematology is briefly reviewed. Topic selections include early descriptions of members of Steinernema and Heterorhabditis, how only morphology was originally used to distinguish between the species; descriptions of the symbiotic bacteria and elucidating their role in the nematode- insect complex, including antibiotic properties, phase variants, and...

Plethodontid Salamander Distributions in Managed Forest Headwaters in Western Oregon, USA

Creator:: Olson, Deanna H. and Kluber, Matthew R.
Abstract:: We examined terrestrial amphibians in managed headwater forest stands in western Oregon from 1998 to 2009. We assessed: (1) temporal and spatial patterns of species capture rates, and movement patterns with distance from streams and forest management treatments of alternative riparian buffer widths and upland thinning; (2) species survival and...

The Influence of fire on the Radiocarbon Signature and Character of Soil Organic Matter in the Siskiyou National Forest, Oregon, USA

Creator:: Heckman, Katherine, Campbell, John, Powers, Heath, Law, Beverly, and Swanston, Chris
Abstract:: Forest fires contribute a significant amount of CO₂ to the atmosphere each year, and CO₂ emissions from fires are likely to increase under projected conditions of global climate change. In addition to volatilizing aboveground biomass and litter layers, forest fires have a profound effect on belowground carbon (C) pools and...

A Hybrid DNA Extraction Method for the Qualitative and Quantitative Assessment of Bacterial Communities from Poultry Production Samples

Creator:: Rothrock, Michael J., Jr., Hiett, Kelli L., Gamble, John, Caudill, Andrew C., Cicconi-Hogan, Kellie M., and Caporaso, J. Gregory
Abstract:: The efficacy of DNA extraction protocols can be highly dependent upon both the type of sample being investigated and the types of downstream analyses performed. Considering that the use of new bacterial community analysis techniques (e.g., microbiomics, metagenomics) is becoming more prevalent in the agricultural and environmental sciences and many...

Swimbladder morphology and specific gravity of myctophids off Oregon

Creator:: Butler, John L. and Pearcy, William G.
Abstract:: Three general types of swimbladders were found in the eight species of myctophids studied: gas-filled, fat-invested, and atrophied or reduced. Small specimens of all species had thin-walled, gas-filled swimbladders. Large specimens of Stenobrachius leucopsarus had fat-invested swim-bladders and large Diaphus theta had either gas-filled or atrophied swimbladders, as found by...

How Good Science and Stories Can Go Hand-In-Hand

Abstract:: What do you say when you have only a minute to explain to a municipal official why keeping track of the number of bird species found in a park may help make decisions about park management? Talk of significant differences among treatments or testing theory will likely meet with glazed...

Menthol-induced bleaching rapidly and effectively provides experimental aposymbiotic sea anemones (Aiptasia sp.) for symbiosis investigations

Creator:: Matthews, Jennifer L., Sproles, Ashley E., Oakley, Clinton A., Grossman, Arthur R., Weis, Virginia M., and Davy, Simon K.
Abstract:: Experimental manipulation of the symbiosis between cnidarians and photosynthetic dinoflagellates (Symbiodinium spp.) is crucial to advancing the understanding of the cellular mechanisms involved in host-symbiont interactions, and overall coral reef ecology. The anemone Aiptasia sp. is a model for cnidarian-dinoflagellate symbiosis, and notably it can be rendered aposymbiotic (i.e. dinoflagellate-free)...
