Population structure of coastal cutthroat trout (Oncorhynchus clarki clarki) in the Muck Creek Basin, Washington

Zimmerman, Christian E. 23 October 1995 (has links)
The relationship of coastal cutthroat trout (Oncorhynchus clarki clarki) populations in the Muck Creek basin, a 238 km�� southern Puget Sound stream basin in western Washington, was examined using starch gel electrophoresis and meristic analysis. Coastal cutthroat trout were collected from six sites throughout the basin including tributaries, portions of the mainstem, and a lake. Four sites contained only resident trout, the lower mainstem contained resident and anadromous trout, and the lake contained only mature anadromous trout based on size and appearance. Patterns of allelic and meristic variation suggest a significant structuring and separation of coastal cutthroat trout populations in the basin. The lake population was distinguished from the other populations by significant differences in allele frequencies and meristic characters. The other sites grouped more closely together with significant variation among and between sites meristically and at several loci. / Graduation date: 1996

Spatial and temporal variation in size and shape of sediment particles in the Tobacco Creek Watershed

Liu, Cenwei Jr 21 January 2015 (has links)
Particle size and shape are important characteristics of the sediment which affects the adsorption of sediment-associate contaminants and nutrients onto the surface of sediment. This thesis characterized the spatial and temporal variation in size and shape of sediment particles in the Tobacco Creek Watershed. A strong correlation between the particle size of suspended sediment and stream discharge was observed. Spatial and temporal variation in size of suspended and channel bed sediment showed that particle size was significantly coarser at the upper reaches and following the rainfall events, but finer at the lower reaches and following the snowmelt events. Image analysis of coarser particles showed that rock fragments are not becoming rounded in short distances, but they reduced in size. The coarser materials from bedrock outcrops can be sources of fine-sized particle during transport. These findings have important implications for understanding suspended sediment dynamics transport in the study watershed.
