marine-derived nutrients algal production salmon nursery lakes Alaska during the past 300 years
2014/4/22
We measured historical changes in sedimentary δ15N and fossil pigments in four lakes with anadromous semelparous salmon and two reference lakes to quantify the degree to which the flux of marine-deriv...

Spatial variability stable isotopes fossil pigments surface sediments Alaskan coastal lakes Constraints on quantitative estimates past salmon abundance
2014/5/4
We quantified spatial patterns of stable isotopes of N and C (δ15N, δ13C) and fossil pigment concentrations in the uppermost 10 mm of sediment (,10 yr) from 74 profundal locations and three spawning-s...
Responses in dissolved nutrients and epilithon abundance to spawning salmon in Southeast Alaska streams
dissolved nutrients epilithon abundance spawning salmon Southeast Alaska streams
2014/5/8
Spawning Pacific salmon (Oncorhynchus spp.) historically transported massive quantities of marine-derived nutrients (MDN) into nutrient-poor streams of the Pacific Northwest. In southeast Alaska, we m...
