Estuarine Habitat and Juvenile Salmon: Current and Historical Linkages in the Lower Columbia River and Estuary
Abstract
Our studies in the lower 100-km of the Columbia River estuary quantified historical habitat changes and provided new information about contemporary abundance patterns, life histories, and habitat associations of Chinook salmon. The conceptual framework for this research defined salmon performance in the estuary as the product of three factors: habitat opportunity, habitat capacity, and the structure/life histories of source populations. Our 2002-2008 survey results provided empirical data to support this framework by quantifying Chinook salmon performance in terms of temporal abundance, life history and stock-group diversity, foraging success, and growth, as well as by quantifying the relationships between stock groups and one or more of these factors. In Part I, we detail our reconstruction of historical habitat opportunities and changes in the estuary as influenced by the tide, river flows, and temperature. In Part II, we depict contemporary habitat opportunities based on present-day patterns of salmon distribution and abundance and upon various physical factors that influence fish access to shallow-water rearing areas. In Part III, we compare the capacity of different wetland and nearshore habitats in supporting juvenile Chinook salmon as indicated by variations in prey availability, salmon diet, and rates of consumption. Finally, in Part IV, we examine the effects of upriver population structure and life histories on estuary rearing behavior and performance, including the…

The most important prey in LCRE subyearling Chinook diets have been adult dipterans (mostly Chironomidae) and amphipods (Americorophium salmonis and the more saline-tolerant A. spinicorne).

These wetland losses have strongly affected habitat availability for migrating and temporarily resident juvenile salmonids.
“These wetland losses have strongly affected habitat availability for migrating and temporarily resident juvenile salmonids (Bottom et al. 2011;Johnson et al. 2015), but SWHA has also been altered by changing hydrology and tides.”

“For nonsalmonids, we measured and released a representative sample of up to 30 individuals of each species, and the remaining nonsalmonids were counted and released (summary in Roegner et al. 2008).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
