Preventing Infectious Hematopoietic Necrosis In Salmonid Fish Along The Columbia River Basin, Whitney L. Wright
Preventing Infectious Hematopoietic Necrosis In Salmonid Fish Along The Columbia River Basin, Whitney L. Wright
OHSU-PSU School of Public Health Annual Conference
Infectious hematopoietic necrosis virus (IHNV) is a member of the Rhabdoviridae family and causes infectious hematopoietic necrosis (IHN) disease in many salmonid species during the juvenile or “fry” stage of life. IHNV is endemic to Western North America and occurs in the Columbia River Basin, where Steelhead and Chinook salmon are the most abundant IHNV-vulnerable species. IHNV can cause an epidemic in wild or farmed stocks, killing 90-95 percent of the fish it infects. Transmission is currently understood to occur by direct exposure through the gills, and the virus is shed typically from asymptomatic or clinically ill carrier adults at …
A Four Year Study Of The Effects Of Substrate Depth On The Survival Of Different Plant Species In Portland, Or, Arjun Viray
A Four Year Study Of The Effects Of Substrate Depth On The Survival Of Different Plant Species In Portland, Or, Arjun Viray
Student Research Symposium
The changes in green roof plant species composition was observed after a four year time period. Twelve plots were planted in either native or non-native species at two different substrate depths according to a 2 by 2 factorial design. The list of original species from installation was used to identify which species survived over time in their respective plots. After four years, 9 out of 12 native species and 13 out of 14 species survived. The high survival of 26 original species must be compared to the colonization of 68 new species. With minimal maintenance, new species colonized plots. Extensive …
Effect Of Spatial Influence On Endophyte Diversity Within Alnus Rubra, Sebastian L. Singleton
Effect Of Spatial Influence On Endophyte Diversity Within Alnus Rubra, Sebastian L. Singleton
Student Research Symposium
Red alders (Alnus rubra) of the Pacific Northwest are characterized as actinorhizal dicotyledons; plants that possess that ability to form symbiotic relationships with endophytic organisms, which result in nitrogen-fixing nodules. In Alders of the order Fagales, such a symbiotic relationship with Frankia bacteria allows these plants to play crucial environmental roles as pioneer species able to colonize and enrich nutrient-deficient soils. This ability has a major impact on ecological succession by enabling other species to establish. Although inoculation with frankia bacteria is known to increase symbiotic nitrogen fixation capabilities of actinorhizal plants, whether they could confer the same benefit to …
