Quantifying Salmon-Derived Nutrient Loads from the Mortality of Hatchery-Origin Juvenile Chinook Salmon in the Snake River Basin

Creator:: Warren, Dana R. and McClure, Michelle M.
Abstract:: Hatchery supplementation of anadromous salmon is extensive across the Pacific Northwest region with millions of juvenile salmon stocked annually. The influence of hatchery-origin fish as prey items in recipient ecosystems has been explored, but influences of these fish on broader stream nutrient dynamics has not been well-studied. Salmon-derived nutrients (SDN)...

Importance of environmental factors for the richness and distribution of benthic macroinvertebrates in tropical headwater streams

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leando G., and Callisto, Marcos
Abstract:: An understanding of the interactions among local environmental factors (e.g., physical habitat and water quality) and aquatic assemblages is essential to conserve biodiversity in tropical and subtropical headwater streams. We evaluated the relative importance of multiple physical and chemical habitat variables that influence the richness of Ephemeroptera, Plecoptera, and Trichoptera...

Is the diet of a typical shredder related to the physical habitat of headwater streams in the Brazilian Cerrado?

Creator:: Ferreira, Wander R., Ligeiro, Raphael, Macedo, Diego R., Hughes, Robert M., Kaufmann, Philip R., Oliveira, Leandro G., and Callisto, Marcos
Abstract:: Macroinvertebrates are important for processing leaf detritus in temperate streams, but studies about their role in tropical streams often present conflicting results. Via digestive tract analyses, we assessed the diets of Phylloicus sp. larvae (Trichoptera: Calamoceratidae), collected from streams of two southeastern Brazil river basins (Araguari, Sao Francisco). We classified...

Non-wadeable river bioassessment: spatial variation of benthic diatom assemblages in Pacific Northwest rivers, USA

Creator:: Pan, Yangdong, Hughes, Robert M., Herlihy, Alan T., and Kaufmann, Philip R.
Abstract:: Current bioassessment efforts are focused on small wadeable streams, at least partly because assessing ecological conditions in non-wadeable large rivers poses many additional challenges. In this study, we sampled 20 sites in each of seven large rivers in the Pacific Northwest, USA, to characterize variation of benthic diatom assemblages among...

Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co-occurring songbirds

Creator:: Hardt, Braelei M., Ardia, Daniel R., Bashaw, Meredith J., and Rivers, James W.
Abstract:: 1. Rearing environments can shape offspring phenotype across taxa, yet little is known about how brood size influences hypothalamic-pituitary axis functioning, whether its expression trades off with growth, and the degree to which these -relationships vary between species. 2. We evaluated how brood size influenced nestling physiological (glucocorticoids) and somatic...

Identification of Burrowing Shrimp Food Sources Along an Estuarine Gradient Using Fatty Acid Analysis and Stable Isotope Ratios

Creator:: Bosley, Katelyn M., Copeman, Louise A., Dumbauld, Brett R., and Bosley, Keith L.
Abstract:: Two species of burrowing shrimp occur in high densities in US West Coast estuaries, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species of shrimp are considered ecosystem engineers as they bioturbate and irrigate extensive galleries within the sediment. While their burrows comprise a dominant...

Defining quantitative stream disturbance gradients and the additive role of habitat variation to explain macroinvertebrate taxa richness

Creator:: Ligeiro, Raphael, Hughes, Robert M., Kaufmann, Philip R., Macedo, Diego R., Firmiano, Kele R., Ferreira, Wander R., Oliveira, Deborah, Melo, Adriano S., and Callisto, Marcos
Abstract:: Most studies dealing with the use of ecological indicators and other applied ecological research rely on some definition or concept of what constitutes least-, intermediate- and most-disturbed condition. Currently, most rigorous methodologies designed to define those conditions are suited to large spatial extents (nations, ecoregions) and many sites (hundreds to...

Associations between forest fragmentation patterns and genetic structure in Pfrimer’s Parakeet (Pyrrhura pfrimeri), an endangered endemic to central Brazil’s dry forests

Creator:: Miller, M. P., Bianchi, C. A., Mullins, T. D., and Haig, S. M.
Abstract:: When habitat becomes fragmented, populations of species may become increasingly isolated. In the absence of habitat corridors, genetic structure may develop and populations risk reductions in genetic diversity from increased genetic drift and inbreeding. Deforestation of the Cerrado biome of Brazil, particularly of the dry forests within the Paran River...
