A cross sectional study of anemia and iron deficiency as risk factors for arsenic-induced skin lesions in Bangladeshi women

Creator:: Kile, Molly L., Faraj, Joycelyn M., Ronnenberg, Alayne G., Quamruzzaman, Quazi, Rahman, Mahmudar, Mostofa, Golam, Afroz, Sakila, and Christiani, David C.
Abstract:: Background: In the Ganges Delta, chronic arsenic poisoning is a health concern affecting millions of people who rely on groundwater as their potable water source. The prevalence of anemia is also high in this region, particularly among women. Moreover, arsenic is known to affect heme synthesis and erythrocytes and the...

Mapping the Global Emergence of Batrachochytrium dendrobatidis, the Amphibian Chytrid Fungus

Creator:: Olson, Deanna H., Aanensen, David M., Ronnenberg, Kathryn L., Powell, Christopher I., Walker, Susan F., Bielby, Jon, Garner, Trenton W. J., Weaver, George, The Bd Mapping Group, and Fisher, Matthew C.
Abstract:: The rapid worldwide emergence of the amphibian pathogen Batrachochytrium dendrobatidis (Bd) is having a profound negative impact on biodiversity. However, global research efforts are fragmented and an overarching synthesis of global infection data is lacking. Here, we provide results from a community tool for the compilation of worldwide Bd presence...

Instream cover and shade mediate avian predation on trout in semi-natural streams

Creator:: Penaluna, Brooke E., Dunham, Jason B., and Noakes, David L. G.
Abstract:: Piscivory by birds can be significant, particularly on fish in small streams and during seasonal low flow when available cover from predators can be limited. Yet, how varying amounts of cover may change the extent of predation mortality from avian predators on fish is not clear. We evaluated size-selective survival...

Riverscape Patterns among Years of Juvenile Coho Salmon in Midcoastal Oregon: Implications for Conservation

Creator:: Flitcroft, R., Burnett, K., Snyder, J., Reeves, G., and Ganio, L.
Abstract:: Patterns of salmon distribution throughout a riverscape may be expected to change over time in response to environmental conditions and population sizes. Changing patterns of use, including identification of consistently occupied locations, are informative for conservation and recovery planning. We explored interannual patterns of distribution by juvenile Coho Salmon Oncorhynchus...

Managing small-acreage horse farms in central and eastern Oregon

Creator:: Oregon State University. Extension Service, Stephenson, Garry Owen, Hannaway, D., Bohle, Mylen G., Brewer, Linda J., Hammond, Ellen, Parsons, Cory, Schreder, Pete, and Fery, Melissa
Abstract:: Some good goals for a well-managed, small-acreage horse farm are: • A productive pasture with plenty of grass and few weeds • Less dust during the dry season and less mud during the wet season • Healthy horses free of problems associated with dust, manure, mud, and toxic plants •...

Managing small-acreage horse farms : for green pastures, clean water, and healthy horses

Creator:: Oregon State University. Extension Service, Stephenson, Garry Owen, and Hannaway, D.
Abstract:: The goals for a well-managed small-acreage horse farm are: A productive pasture with plenty of grass and few weeds Almost no mud during the rainy season All nutrients (manure and stall waste) generated by the horses recycled to feed the pasture or removed from the farm and recycled Healthy horses...

Detection of the emerging amphibian pathogens Batrachochytrium dendrobatidis and ranavirus in Russia

Creator:: Reshetnikov, Andrey N., Chestnut, Tara, Brunner, Jesse L., Charles, Kaylene, Nebergall, Emily E., and Olson, Deanna H.
Abstract:: In a population of the European common toad Bufo bufo from a rural pond in the region of Lake Glubokoe Regional Reserve in Moscow province, Russia, unexplained mass mortality events involving larvae and metamorphs have been observed over a monitoring period of >20 yr. We tested toads from this and...

BlausteinAndrewZoologyHostSpeciesComposition.pdf

Creator:: Han, Barbara A., Kerby, Jacob L., Searle, Catherine L., Storfer, Andrew, and Blaustein, Andrew R.
Abstract:: Wildlife epidemiological outcomes can depend strongly on the composition of an ecological community, particularly when multiple host species are affected by the same pathogen. However, the relationship between host species richness and disease risk can vary with community context and with the degree of spillover transmission that occurs among co-occurring...

Heterogeneous Occupancy and Density Estimates of the Pathogenic Fungus Batrachochytrium dendrobatidis in Waters of North America

Creator:: Chestnut, Tara, Anderson, Chauncey, Popa, Radu, Blaustein, Andrew R., Voytek, Mary, Olson, Deanna H., and Kirshtein, Julie
Abstract:: Biodiversity losses are occurring worldwide due to a combination of stressors. For example, by one estimate, 40% of amphibian species are vulnerable to extinction, and disease is one threat to amphibian populations. The emerging infectious disease chytridiomycosis, caused by the aquatic fungus Batrachochytrium dendrobatidis (Bd), is a contributor to amphibian...

Near-Term Effects of Repeated-Thinning with Riparian Buffers on Headwater Stream Vertebrates and Habitats in Oregon, USA

Creator:: Olson, Deanna H. and Burton, Julia I.
Abstract:: We examined the effects of a second-thinning harvest with alternative riparian buffer management approaches on headwater stream habitats and associated vertebrates in western Oregon, USA. Our analyses showed that stream reaches were generally distinguished primarily by average width and depth, along with the percentage of the dry reach length, and...
