Assessing the Effects of Contemporary Forest Harvest on Headwater Stream Food Webs in the Oregon Coast Range

Creator:

Mowlds, Emilee A.

Abstract:

Food webs are fundamental in ecology, as they offer a way to better understand the interrelatedness, connectivity, and complexity within a given ecosystem. The use of network analysis to model food webs can provide insights about the importance of physical templates on the organization of biological systems in streams using...

Seasonal Movement of Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) in Headwater Streams in Oregon

Creator:

Linkem, Christina N.

Abstract:

Headwater streams in the Oregon Coastal Range are subject to drastic fluctuations in flow and temperature because of the changing seasonality of a Mediterranean climate. In response to these changes, stream fishes exhibit a variety of movement patterns. Coastal Cutthroat Trout (Oncorhynchus clarkii clarkii) have evolved an assortment of life...

Factors influencing population density of stream-living Redband Trout in southeast Oregon, USA

Creator:

Thorson, Justin M.

Abstract:

Fisheries managers often use models of population density to evaluate the status of stream-living fishes, but many of these models have low predictive performance for abundance and density. These models could incorporate several factors that can limit population density, particularly the effect of body size, envisioned by the theory of...

Changes in Otolith Shape in Juvenile Chinook Salmon in Different Hatchery Rearing Conditions

Creator:

Ehrke, Melissa A.

Abstract:

The decline of the Chinook Salmon has been a mystery of recent years due to their decline. It has been speculated that wild origin salmon have more vigor and survivability than hatchery reared fish. This is thought to be due to rearing conditions, possibly affecting sensory organ development. The sensory...

Water intake structures as movement barriers for larval coastal giant salamanders (Dicamptodon tenebrosus)

Creator:

Eaton, Jordan E.

Abstract:

Dams, culverts, and water intake structures can impact the movement of aquatic and semi-aquatic species within streams and rivers. Datagaps exist regarding the impact of water intake structures on larval coastal giant salamanders (Dicamptodon tenebrosus) as these obstructions may produce a barrier to up and downstream movement. The Rock Creek...
