The Expression of Leptin, Estrogen Receptors, and Vitellogenin mRNAs in Migrating Female Chum Salmon, Oncorhynchus keta: The Effects of Hypo-osmotic Environmental Changes
Chum Salmon Estrogen Receptors Leptin Maturation Salinity Change Vitellogenin
2016/5/16
Leptin plays an important role in energy homeostasis and reproductive function in fish, especially in reproduction. Migrating fish, such as salmonoids, are affected by external environmental factors, ...
Regularity "in Large" for the 3D Salmon's Planetary Geostrophic Model of Ocean Dynamics
planetary geostrophic model global regularity ocean dynamics model global circulation
2011/2/28
It is well known, by now, that the three-dimensional non-viscous planetary geostrophic model,
with vertical hydrostatic balance and horizontal Rayleigh friction, coupled to the heat diffusion and tra...
Toward a salmon conjecture
salmon conjecture
2010/12/15
By using a result from the numerical algebraic geometry package Bertini we show that (with extremely high probability) a set of degree 6 and degree 9 polynomials cut out the secant variety 4(P2 × P2 ...
Variability in stream discharge and temperature：a preliminary assessment of the implications for juvenile and spawning Atlantic salmon
Critical Displacement Velocity Atlantic salmon
2009/5/18
This study focuses on understanding the temporal variability in hydrological and thermal conditions in a small mountain stream and its potential implication for two life stages of Atlantic salmon (Sal...
Implications of climate change on flow regime affecting Atlantic salmon
UKCIP02 climate change Atlantic salmon flow regime hydiaulic characteristics RRV analysis
2009/5/8
The UKCIP02 climate change scenarios (2070–2100) suggest that the UK climate will become warmer (an overall increase of 2.5–3°C), with temperature increases being greater in the summer and autumn than...
Water quality limits for Atlantic salmon (Salmo salar L.) exposed to short term reductions in pH and increased aluminum simulating episodes
acid neutralizing capacity pH Atlantic salmon
2009/4/29
Acidification has caused the loss or reduction of numerous Atlantic salmon (Salmo salar L.) populations on both sides of the North Atlantic. Acid deposition peaked in the 1980's and resulted in both c...
Ecological, landscape, and climatic regulation of sediment geochemistry in North American sockeye salmon nursery lakes: Insights for paleoecological salmon investigations
sediment geochemistry Ecological landscape climatic
2014/4/17
We used multiple linear regressions across a Northeast Pacific region 56-lake set to examine the influence of
sockeye salmon spawner densities and limnological, climatic, and watershed characteristic...
The influence of riparian woodland on the spatial and temporal variability of stream water temperatures in an upland salmon stream
temperature forest hydrology Cairngorm
2009/3/5
The spatio-temporal variability of stream water temperatures was investigated at six locations on the Girnock Burn (30km2 catchment), Cairngorms, Scotland over three hydrological years between 1998 an...
Salmon influences on dissolved organic matter in a coastal temperate brownwater stream: An application of fluorescence spectroscopy
Salmon dissolved organic matter temperate brownwater stream:fluorescence spectroscopy
2014/4/22
We examined how spawning Pacific salmon (genus Oncorhynchus) affect streamwater concentrations of inorganic nitrogen and phosphorus and dissolved organic matter in Peterson Creek, a stream in southeas...
Variable effects of marine-derived nutrients on algal production in salmon nursery lakes of Alaska during the past 300 years
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...
Long-term changes in legacy trace organic contaminants and mercury in Lake Ontario salmon in relation to source controls, trophodynamics, and climatic variability
legacy trace organic contaminants mercury
2014/5/5
We used long-term (20+ yr) datasets to determine how the sum of 209 polychlorinated biphenyl congeners
([SPCB]), dodecachloropentacyclodecane ([mirex]), para-para dichlorodiphenyltrichloroethane ([ p...
The influence of nitrogen limitation on d15N and carbon : nitrogen ratios in sediments from sockeye salmon nursery lakes in British Columbia, Canada
nitrogen limitation on d15N and carbon nitrogen ratios in sediments sockeye salmon nursery lakes British Columbia Canada
2014/5/5
Carbon (C) and nitrogen (N) elemental and nitrogen isotopic ratios were determined for bulk organic matter in surface sediments of 11 sockeye salmon (Onchorynchus nerka) nursery lakes in British Colum...
Spatial variability of stable isotopes and fossil pigments in surface sediments of Alaskan coastal lakes: Constraints on quantitative estimates of past salmon abundance
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...

Salmon-derived mercury nutrients Lake Ontario spawning stream
2014/5/19
We tested the hypothesis that concentrations of mercury species (Hg) and nutrients (NH4+, NO3-, P, and dissolved organic carbon) in abiotic and biotic components would be altered by the decomposition ...
