Using Catch Data to Estimate Changes in Global Commercial Abalone Abundance
Fisheries Management and Ecology, EarlyView.ABSTRACT Changes in global wild capture production of abalone are explored to infer potential changes in biological stocks. The study found that 77% (or 10 out of the 13) of the countries that reportedly caught abalone in the wild have experienced declines in catches between 1980 and 2023, and on aggregate catch declined by almost 83% between 1980 and ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression
Journal of Systematics and Evolution, EarlyView.Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...
