Abstract Widespread declines in Atlantic and Pacific salmon ( Salmo salar Oncorhynchus spp.) have tracked recent climate changes, but managers still lack quantitative projections of the viability any individual population response to future change. To address this gap, we assembled a vast database survival other data for eight wild populations threatened Chinook O. tshawytscha ). For each population, evaluated impacts at all life stages modeled trajectories forced by global model...
Segmental renal artery branches within the sinus were prospectively evaluated with color Doppler imaging and pulsed-Doppler spectral analysis in 56 patients before angiography. Waveforms for tardus parvus abnormalities of prolonged acceleration time, diminished index, loss normal early systolic compliance peak/reflective-wave complex (ESP). Findings obtained these parameters compared subsequent findings on angiograms to ascertain their efficacy detection hemodynamically significant (greater...
The relationships among behavior, environment, and migration success in anadromous fishes are poorly understood. We monitored behavior at eight Columbia Snake river dams for 18 286 adult Chinook salmon (Oncorhynchus tshawytscha) steelhead (sea-run Oncorhynchus mykiss) over 7 years using radiotelemetry. When statistically controlling variation flow, temperature, fisheries take, other environmental variables, we observed that unsuccessful individuals — those not to reach spawning areas had...
Climate change is likely to the relationships between commonly used climate indices and underlying patterns of variability, but this complexity rarely considered in studies using indices. Here, we show that physical ecological conditions mapping onto Pacific Decadal Oscillation (PDO) index North Gyre (NPGO) have changed over multidecadal timescales. These changes apparently began around a 1988/1989 shift was marked by abrupt northeast warming, declining temporal variance Aleutian Low (a...
Many marine mammal predators, particularly pinnipeds, have increased in abundance recent decades, generating new challenges for balancing human uses with recovery goals via ecosystem-based management. We used a spatio-temporal bioenergetics model of the Northeast Pacific Ocean to quantify how predation by three species pinnipeds and killer whales (Orcinus orca) on Chinook salmon (Oncorhynchus tshawytscha) has changed since 1970s along west coast North America, compare these estimates...
Abstract Climate change has been associated with both latitudinal and elevational shifts in species’ ranges. The extent, however, to which climate driven recent range alongside other putative drivers remains uncertain. Here, we use the changing distributions of 378 European breeding bird species over 30 years explore dynamics, considering effects climate, land cover, environmental variables, traits on probability local colonisation extinction. On average, shifted their ranges by 2.4 km/year....
Most modeling and statistical approaches encourage simplicity, yet ecological processes are often complex, as they influenced by numerous dynamic environmental biological factors. Pacific salmon abundance has been highly variable over the last few decades most forecasting models have proven inadequate, primarily because of a lack understanding affecting variability in survival. Better methods data for predicting returning adults therefore required to effectively manage species. We combined...
Fisheries oceanography is the study of ecological relationships between fishes and dynamics their marine environments aims to characterize physical, chemical, biological factors that affect recruitment abundance harvested species.A recent push within fisheries management community toward ecosystem-based management.Here, we show how physical data can be used generate indicators ocean conditions in an ecosystem context, these relate salmonids, sablefish, sardines, rockfish California Current.
The California Current System (CCS) has experienced large fluctuations in environmental conditions recent years that have dramatically affected the biological community. Here we synthesize remotely sensed, hydrographic, and survey data from throughout CCS 2019–2020 to evaluate how changes community dynamics at multiple trophic levels. A marine heatwave formed north Pacific 2019 reached second greatest area ever recorded by end of summer 2020. However, high atmospheric pressure early 2020...
2022 marked the third consecutive La Niña and extended longest stretch of negative Oceanic Niño Index since 1998-2001. While physical biological conditions in winter spring largely adhered to prior conditions, summer fall were very different. Similar past events, coastal upwelling was either average or above average, temperature below salinity generally average. In fall, however, slightly close chlorophyll a Again, as during biomass northern/southern copepods above/below off Oregon winter,...

Accurate estimates of escapement by adult anadromous salmonids are difficult, especially in large, multistock river systems. We used radiotelemetry and a fishery reward program to calculate escapement, harvest, unaccounted for loss rates 10 498 chinook salmon (Oncorhynchus tshawytscha) 5324 steelhead mykiss) during six return years the Columbia River basin. Mean annual escapements spawning sites, hatcheries, or upper bounds monitored hydrosystem were 73.4% (springsummer salmon), 61.3% (fall...
Chemotherapeutic drugs are widely used for the treatment of cancer; however, use these is often associated with patient toxicity and poor tumor delivery. Micellar drug carriers offer a promising approach formulating achieving improved delivery hydrophobic chemotherapeutic drugs; conventional micelles do not have long-term stability in complex biological environments such as plasma. To address this problem, novel triblock copolymer has been developed to encapsulate several different into...
Abstract It is generally accepted that climate change will stress coldwater species such as Pacific salmon. However, it unclear what aspect of altered thermal regimes (e.g., warmer winters, springs, summers, or increased variability) have the greatest effect, and role spatial properties river networks play. Thermally diverse habitats may afford protection from by providing opportunities for aquatic organisms to find use with optimal conditions growth. We hypothesized climate‐altered growth...
Ocean fisheries often target and catch aggregations comprising multiple populations or groups of a given species. Chinook salmon (Oncorhynchus tshawytscha) originating from rivers throughout the west coast North America support mixed-stock ocean other ecosystem components, notably as prey for marine mammals. We construct first coastwide state-space model fall tagged fish released California to British Columbia between 1977 1990 estimate seasonal distribution along America. incorporate...
Early summer growth for juvenile coho salmon (Oncorhynchus kisutch) has been assessed in the Northern California Current (NCC) since 2000. Mean insulin-like factor 1 (IGF1) levels (an indicator of growth) differed significantly over succeeding decadal intervals (2000–2009 vs. 2011–2022) with IGF1 2010 being consistently higher than found before 2010. Across time series, were correlated a prey index derived from plankton samples collected upper water column during surveys. There are no...
Thermal layering in reservoirs upstream from hydroelectric dams can create temperature gradients fishways used by migrating adults. In the Snake River, Washington, federally-protected adult salmonids (Oncorhynchus spp.) often encounter relatively cool water dam tailraces and lower ladder sections warmer portions of ladders. Using radiotelemetry, we examined relationships between fish passage behavior difference top bottom ladders (∆T) at four over years. Some spring Chinook salmon (O....
Abstract We used microsatellite DNA data and genetic stock identification methods to delineate the temporal spatial distributions of juvenile Chinook Salmon Oncorhynchus tshawytscha occupying coastal habitats extending from central Oregon northern Washington. Juveniles were collected in trawl surveys conducted during spring, summer, autumn over 15 years. Distributions (mean latitude distance shore) differed between yearling subyearling life history types stocks; many these differences...
In late 2020, models predicted that a strong La Niña would take place for the first time since 2013, and we assessed whether physical biological indicators in 2021 were similar to past Niñas California Current Ecosystem (CCE). The Pacific Decadal Oscillation Oceanic Niño Index indeed remained negative throughout 2021; North Gyre Index, however, strongly negative. seventh largest marine heatwave on record was unexpectedly present from April end of Niñas, this mass warm water mostly seaward...

6013 Background: Interrupting the epidermal growth factor receptor (EGFR) signaling pathway has shown promise in a variety of cancers and preclinical data demonstrated possible synergy with platinums taxanes. Treatment options for recurrent/metastatic HNSCC are limited. A study cisplatin docetaxel showed response rate 40% 9.6 month median survival. Erlotinib, an EGFR tyrosine kinase inhibitor, had 4.3% as single agent HNSCC. Because efficacy, we proposed to combination cisplatin, erlotinib...
Migrating animals rely on a variety of cues to guide them, but the relative importance those signals may vary with size, life stage, or location. During their initial ocean migration, yearling Chinook salmon (Oncorhynchus tshawytcha) from Columbia River have stock-specific spatial distributions that shift through time. We used two-process mixture model examine how distribution migrants three stocks varies as function geospatial (e.g., latitude and distance shore) environmental chlorophyll...
