Estimating population size and observation bias for spring Chinook Salmon

Conservation Science and Practice, 2019
The primary conservation prioritization tool for spring Chinook Salmon (Oncorhynchus tshawytscha), population viability analysis, is often conducted with biased spawner abundance data with no associated statistical uncertainty or error.

Percent change in spawner abundance resulting from each of the diagnostic scenarios of habitat change.

, 2021
Colors represent the percent change in spawner abundance in each Ecological Region and scenario relative to the abundance of the Ecological Region in the current condition. Ecological Regions in gray have no spawners.

Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Still more spawner-recruitment curves: the hockey stick and its generalizations

, 2000
Estimation of maximum reproductive rate using spawner-recruitment models involves extrapolating survival for very low spawner abundance. Existing spawner-recruitment curves often lead to biologically unreasonable extrapolations or are unable to model ...

Change in spawner abundance by Ecological Region for each population and restoration scenario for late-century.

, 2022
Change in spawner abundance represents a change from the late-century No action scenario. Gray regions are outside of the spawning and rearing distributions for a given population.

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

Advanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Life-history habitat suitability modelling of a potential invasive alien species, smallmouth bass (Micropterus dolomieu), in South Korea

Ecological Indicators, 2023
The aim of this study was to predict the distribution of a potential invasive alien species, smallmouth bass (Micropterus dolomieu), in South Korea using a life-history-based habitat suitability model.

Adult spawners: A critical period for subarctic Chinook salmon in a changing climate

Global Change Biology, 2023
AbstractConcurrent, distribution‐wide abundance declines of some Pacific salmon species, including Chinook salmon (Oncorhynchus tshawytscha), highlights the need to understand how vulnerability at different life stages to climate stressors affects population dynamics and fisheries sustainability.

Spawner-recruit relationships and fish stock carrying capacity in aquatic ecosystems

, 2003
Few marine ecologists have addressed important questions about the relative productivity and carrying capacity of different ecosystems required to support fish populations. Whereas many researchers have investigated interannual variability in recruitment

Beyond Probiotics: Postbiotics for Healthy Aquaculture

Advanced Science, EarlyView.
This critical review assesses limitations of probiotics and proposes postbiotics, preparations of inanimate microorganisms and their metabolites, as a more stable, controlled, and biosafe formulation. Postbiotics offer significant advantages during industrial aquafeed production and storage. However, their practical implementation is currently hindered
