Phylogeography of the widely distributed John Dory (Zeus faber, Actinopterygii: Zeiformes) reaffirms the prevalence of at least two deeply divergent clades

open access: yesJournal of Fish Biology, EarlyView.
Abstract The John Dory Zeus faber is a commercially exploited demersal fish species with a known distribution ranging from the Northeast Atlantic to parts of the Indian and Pacific oceans. A previous genetic survey using cytochrome c oxidase subunit I (COI) DNA barcodes suggested the presence of two geographically segregated taxonomic units within Z ...

Classification of European Illex coindetii and Loligo forbesii Squid Stocks by Trace Element Analysis of Statoliths

open access: yesFisheries Management and Ecology, Volume 33, Issue 2, Page 181-200, April 2026.
ABSTRACT We investigated whether statolith microchemistry analysis could classify ommastrephid and loliginid squid species into fishery stocks. Statolith nucleus (early life stage) and edge (life stage at time before catch) of Illex coindetii (Verany, 1839) and Loligo forbesii (Steenstrup, 1856) from various areas of the North East Atlantic Ocean and ...

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Global Long‐Term Trends in Ionospheric TEC From GNSS Observations With Local‐Time Dependence

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Long‐term ionospheric changes are expected as a consequence of thermospheric cooling driven by increasing greenhouse gas concentrations. We analyze global ionospheric total electron content (TEC) derived from GNSS observations for 2000–2024 using the high‐resolution ISEE data set.
