Efficacy of injectable tulathromycin for reduction of vertical transmission of Renibacterium salmoninarum in Spring Chinook Salmon Oncorhynchus tshawytscha
Diane Elliott
2018, Report
Bacterial kidney disease (BKD) caused by Renibacterium salmoninarum (Rs) occurs nearly worldwide where wild or cultured salmonid fishes are present. Control of BKD is confounded by its two modes of transmission, horizontal (fish-to-fish) and vertical (from female parent to progeny via the eggs). A highly successful BKD control strategy employed...
Developing a global earthquake risk model
Vitor Silva, Helen Crowley, Kishor S. Jaiswal, Ana Beatriz Acevedo, Massimiliano Pittore, Murray Journey
2018, Conference Paper, Proceedings of 16th European Conference on Earthquake Engineering
The understanding of earthquake risk is the first step towards the development and implementation of disaster risk reduction measures. However, in many countries, especially the countries of the developing world, earthquake risk models either do not exist or are publicly inaccessible. The Global Earthquake Model (GEM) Foundation and its partners have been supporting...
Basin-scale model for predicting marsh edge erosion
Navid H. Jafari, Qin J. Chen, Brady Couvillion, Cody L. Johnson, Thomas Everett
2018, Conference Paper, Coastal Engineering Proceedings
Recent attempts to relate marsh edge retreat rate to wave power have met varying levels of success. Schwimmer (2001) correlated wave power to marsh boundary retreat rates over a five-year period along sites within Rehoboth Bay, Delaware, USA. Marani et al. (2011) derived a linear relationship between volumetric retreat rate...

Streams do work: Measuring the work of low-order streams on the landscape using point clouds
Ethan J. Shavers, Larry V. Stanislawski
2018, Conference Paper, International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences - ISPRS Archives
The mutable nature of low-order streams makes regular updating of surface water maps necessary for accurate representation. Low-order streams make up roughly half the streams in the conterminous United States by length, and small inaccuracies in stream head location can result in significant error in stream reach, order, and density....
