Introduction Understanding how abundance, productivity and distribution of individual species may respond to climate change is a critical first step towards anticipating alterations in marine ecosystem structure function, as well developing strategies adapt the full range potential changes. Methods This study applies NOAA (National Oceanic Atmospheric Administration) Fisheries Climate Vulnerability Assessment method 64 federally-managed California Current Large Marine Ecosystem assess their...
From fishers to farmers, people across the planet who rely directly upon natural resources for their livelihoods and well-being face extensive impacts from climate change. However, local- regional-scale associated risks can vary geographically, implications development of adaptation pathways that will be most effective specific communities are underexplored. To improve this understanding at relevant local scales, we developed a coupled social-ecological approach assess risk posed fishing...

While algal community composition has been examined as a qualitative indicator of postmortem submersion interval (PMSI), there have no quantitative studies on using growth rates PMSI estimators. The present study was undertaken to examine pig decomposition in streams and develop more approach estimate PMSI. Pigs ceramic tiles were completely submerged regularly sampled for periphyton growth. Five stages identified the carcasses according physical characteristics. Algal rates, measured...
The alternating translucent and opaque banding pattern in canary rockfish (Sebastes pinniger) otoliths, aged using a break-and-burn methodology, are annual markings. To validate age assignment, we compared measured radiocarbon levels otolith cores with reference chronology developed from known Pacific halibut (Hippoglossus stenolepis). An average 2- to 3-year phase shift was detected between the that likely result of differences regional oceanography or underageing bias. assumption ageing...

Identifying juvenile habitats is critical for understanding a species' ecology and focusing spatial fishery management by defining references like essential fish habitat (EFH). Here, we used vector autoregressive spatio-temporal models (VAST) to delineate temporal patterns in density 13 commercially important species of groundfishes off the US west coast. In particular, identified hotspots with high density. Three qualitative distribution abundance emerged. First, Dover sole Microstomus...
Generating biomass-at-age indices for fisheries stock assessments with acoustic data collected by uncrewed surface vessels (USVs) has been hampered the need to resolve backscatter contemporaneous biological (e.g., age) composition data. To address this limitation, Pacific hake ( Merluccius productus ; “hake”) were gathered from a USV survey (in 2019) and acoustic-trawl (ATS; 2019 eight previous years), fishery-dependent non-target (i.e., not specifically targeting hake) fishery-independent...
Abstract The bomb radiocarbon chronometer has become a standard tool for assessing the accuracy of otolith‐based fish age estimates. Use depends upon increase in 14 C that occurred due to atmospheric testing nuclear weapons middle 20th century. In previous analyses, variety ad hoc methods have been used compare test chronologies with reference chronologies. This paper proposes deterministic coupled‐functions model describes and standardizes facilitates comparisons within across species. this...
