The influence of canopy type and seasons on adult aquatic insect emergence and riparian spiders in the Oregon Coast Range

Creator:

Premdas, Sharmila

Abstract:

The objective of my study was to examine differences in riparian tree and shrub composition associated with adult aquatic emergence and implications for terrestrial spiders in these sites. Seasonal abundance and biomass of adult emergent aquatic insects, riparian arthropod abundances and spider densities were compared between conifer- and hardwood-dominated sites...

Seasonal influences on food availability and diet of coastal cutthroat trout in relation to riparian vegetation

Creator:

Romero, Nicolas

Abstract:

Current riparian management objectives in the Pacific Northwest promote both retention of existing conifers and conversion of hardwood-dominated areas to conifers. Although understanding of relationships between riparian vegetation and salmonid prey availability is growing, temporal variation in these relationships is poorly understood. Seasonal fluxes in availability of aquatic and terrestrial...

Seasonal dynamics of a riparian food web in the Oregon Coast Range mountains

Creator:

Robillard, Amanda Lynn

Abstract:

Riparian areas are eco-tones where aquatically- and terrestrially-derived insect biomass is exchanged between habitats, presenting consumers with new sources of energy, and resulting in a reciprocal subsidy. The relative contribution of energy exchange and the resulting impacts on vertebrate riparian consumers, such as fish or birds, remains poorly understood. We...
