The status and life history traits of endemic, native and introduced species in Lake Lanao, Philippines

Creator:: Ismail, Gladys B.
Abstract:: The endemic cyprinids of Lake Lanao, Philippines have been described as a species flock and are thought to be an example of explosive evolution. However, based on historical surveys, 16 of the 18 cyprinid species endemic to Lake Lanao are now believed to be extinct. Furthermore, non-native species have been...

The relationships between fluctuations in oceanographic conditions, forage fishes, predatory fishes, predator food habits, and juvenile salmonid marine survival off the Columbia River

Creator:: Emmett, Robert L.
Abstract:: Salmonid run sizes are strongly affected by their early marine stage. Fully understanding the life history of salmonids means understanding how they interact with their marine environment and with other fishes. Changes in the biological and physical environment off the Columbia River region affects the distribution and abundance of predatory...

The China Connection : A Glimpse of Collaborative Research Between China and Oregon State University

Creator:: Kenny, Kimberly
Abstract:: China’s global influence in the realm of science and technology (S&T) has increased dramatically in recent times. China and the United States are now each other’s main partner in scientific collaboration. As a major research university, OSU is one of the institutions with a large stake in this international collaboration....

Survival and behavior of juvenile steelhead trout (Oncorhynchus mykiss) in two small estuaries in Oregon

Creator:: Romer, Jeremy D.
Abstract:: A number of steelhead (Oncorhynchus mykiss) populations are at risk throughout Oregon, including five populations that are federally listed as threatened or endangered. However, little is known about behavior and survival of these fish as they transition from freshwater to seawater. We investigated whether estuarine survival varies on a temporal...

Stock Synthesis Assessments of Spatially Structured Fish Populations with an Environmental Driver on Recruitment Distribution : A Simulation Study and Discussion

Creator:: Denson, LaTreese S.
Abstract:: Stock assessments use statistical models and empirical data to re-create the population dynamics of a stock in order to provide estimates of biomass and fishing mortality rates to inform fisheries management. Fish stocks are not uniformly distributed across spatial regions, but stock assessments typically ignore stock spatial structure, for the...

Sensitivity of the stock synthesis assessment model : a simulation approach

Creator:: Yin, Yanshui
Abstract:: Stock assessments for many U.S. Pacific coast groundfish stocks are developed using the catch-at-age method known as Stock Synthesis. In this work a simulation package was developed and used to evaluate the sensitivity of the Stock Synthesis program. More specifically, the evaluation focused on the impacts of input data errors...

Selection for Persistence in Red Clover through Improved Tolerance to Northern Anthracnose [NA; Kabatiella caulivora (Kirch.) Karak.] and Drought

Creator:: Sahin, Muhammet
Abstract:: Twenty-three red clover cultivars and accessions were grown in Boyd, KY, and Philomath, OR to evaluate their tolerance of northern anthracnose [NA; Kabatiella caulivora (Kirch.) Karak.] and drought, dry matter (DM) production, and their agro-morphological characteristics. The key research questions of this study were the influence of NA on yield...

Qualitative analysis of sardine and anchovy oscillations and implications for the management of sardine and anchovy fisheries in Oman

Creator:: Al-Jufaili, Saud M.
Abstract:: Sardines and anchovies are small pelagic fishes that support important commercial fisheries around the world. This project reviews the inverse cyclic behavior in the abundance of these two stocks, which is a striking feature in many regions. In addition, the project used qualitative loop analysis techniques to analyze the feasible...

Oceanographic effects on the dynamics of food habits and growth condition of some groundfish species of the Pacific Northwest

Creator:: Lee, Yong Woo
Abstract:: Marine fish are subject to direct and indirect oceanographic variations operating at short and long time scales. In this study feeding habits and long-term growth condition of several groundfish species of the Pacific Northwest are examined to understand the relationship between variations in the fish's biological and life history components...

Modeling the energetics of Steller sea lions (Eumetopias jubatus) along the Oregon Coast

Creator:: Malavear, Maria Yolanda Garcia
Abstract:: A dynamic bioenergetic model for Steller sea lions (Eumetopias jubatus) was built using the STELLA simulation modeling system. The model is intended as an aid for the exploration of ecological questions regarding growth and survival of immature Steller sea lions (ages 1-3) living along the Oregon coast under different nutritional...
