A study of the vocal behavior of the American robin

Creator:: Benson, Jane Rae
Abstract:: To gain a better foothold on the communication system of the avifauna, calls and songs of the American Robin (Turdus migratorius) were recorded and analyzed using the sound spectrograph. Ten different calls were recognized as follows: three alarm calls, an excitement call, challenge call, contact call, two flight calls and...

The combined effects of vegetation control and seedling size class on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedling productivity on a site in Oregon

Creator:: Lefebvre, Robert F.
Abstract:: Controlling competing vegetation with the application of herbicides and increased seedling size at planting has been shown to increase seedling survival and growth. These two important reforestation tools have often been studied independently of each other, limiting comparisons that can be made between them. This study utilized a factorial treatment...

Steller sea lions (Eumetopias jubatus) of Oregon and Northern California: seasonal haulout abundance patterns, movements of marked juveniles, and effects of hot-iron branding on apparent survival of pups at Rogue Reef

Creator:: Scordino, Jonathan
Abstract:: The Steller Sea Lion Research Initiative was passed in 2001 to provide funding to help scientists determine causes and solutions for the population crash of Steller sea lions (Eumetopias jubatus). In response to need to understand population dynamics of Steller sea lions, NOAA Fisheries has spearheaded a large-scale, range-wide research...

Robin : an experimental protocol for asynchronous serial lines

Creator:: Chum, Hon Pan
Abstract:: Computer networking research has been going on for almost twenty years; however, most of the protocols concern high and low speed synchronous transmission. All synchronous communication needs special transmission lines. The TCP/IP (Transmission Control Protocol/Internet Protocol) protocols, Ethernet, X.25, X windows system are very successful protocols. Less work has been...

Irrigation and plant density effects on head rot and yield of broccoli

Creator:: Ludy, Robin L.
Abstract:: Effects of amount of applied water and frequency of irrigation on head rot and yield of three broccoli cultivars were evaluated in 1987 and 1988. Two irrigation frequencies were established with a line-source sprinkler system for 5.5 weeks during heading. The low-frequency experiment was watered once per week and the...

Within and between plant dispersal and distributions of adult females and immatures of Neoseiulus californicus and N. fallacis (Acari: Phytoseiidae) in bean and apple plant systems

Creator:: Pratt, Paul D. (Paul David), 1970-
Abstract:: Intra- and interplant movement and dispersal of the predator mites Neoseiulus californicus (McGregor) and Neoseiulus fallacis (Garman) were studied on both lima bean (Phaseolus lunatus L.) and apple (Malus pumila Miller) branch plant systems that were seeded with excess numbers of the spider mite Tetranychus urticae Koch. Individuals of either...

Enhanced efficiency nitrogen fertilizers for nitrogen management in the Columbia Basin, Oregon

Creator:: Holcomb, Jess Charles
Abstract:: Ammonia (NH₃) volatilization can result in a substantial amount of surface applied nitrogen (N) being lost into the atmosphere, making it an environmental pollutant as well as reducing plant-available N. However, N can also be easily lost from the soil through leaching, and nitrous oxide (NO₂). Enhanced efficiency N fertilizers...

Adaptation of molecular filtration for recovery of fish viruses from water

Creator:: Watanabe, Robin Aiko
Abstract:: The effectiveness of tangential flow filtration (TFF) for recovery of infectious hematopoietic necrosis virus (IHNV) and infectious pancreatic necrosis virus (IPNV) from large volumes of water was evaluated. In laboratory studies, virus recovery from IHNV-seeded water following concentration by TFF was approximately 13%. However, addition of 0.1 and 1% FBS...
